At that time, all the righteous armies, whether they were marshals, managers, or grass-headed kings from all walks of life, all wanted to worship 'Zhao Lin'er', the emperor of the Great Song Dynasty.

And he, Liu Futong, is the prime minister of the Great Song Dynasty, one person is above 10,000 people.

Only in this way can the rebel armies gather their strength and overthrow the tyrant together.

"Don't worry, Generalissimo, I'll send someone to Bozhou to find it!" Mr. Kwan said.

"This matter is not too anxious, send more people to find it quietly, don't be too loud, it's not good to let others know." Liu Futong said cautiously.

Han Shantong's prestige among the Red Turban Army White Lotus Sect was extremely high, and his son Han Lin'er naturally had considerable value.

In addition to Liu Futong, many other people are also looking for Han Lin'er.

Everyone wants to use Han Lin'er as a big signboard to command the rebels from all walks of life.

Liu Futong naturally didn't want to be snatched away by others.

"Don't worry, Generalissimo, I will definitely look for it quietly." Mr. Guan said seriously.

Liu Futong thought for a moment, and then continued.

"Mr. Guan, I think Zhu Yuanzhang is there, it's best for you to take a trip for me, saving others to spoil such a good thing."

Looking at the rebels from all walks of life, it can be said that there is no one else who can have surplus food to support them except Zhu Yuanzhang.

Liu Futong naturally attaches great importance to it.

"No problem, then I'll go there myself and see this Zhu Yuanzhang!" Mr. Guan happily agreed.

Zhu Yuanzhang's rapid rise has already filled Guan Duo's heart with curiosity.

This monk of Longxing Temple conquered Haozhou as soon as he raised his troops, and then he was defeated in Shayuan, then he broke through Dingyuan, and then he went south to remove the state.

It's all a tough battle!

I really don't know how Zhu Yuanzhang quickly defeated the enemy.

Guan Duo had long wanted to see it for himself.

After receiving Liu Futong's order, Guan Duo led a team of elite soldiers to embark on a journey south to the state the next day.

Guan Duo and his entourage first went to Haozhou, first met Guo Zixing, the marshal of Haozhou, and others, and then went south to Dingyuan to find Zhu Yuanzhang.

As soon as they arrived in Haozhou City, Guo Zixing, Sun Deya and others warmly welcomed Guan Duo and others.

At the banquet, Guan Duo keenly noticed that Guo Zixing, Sun Deya and others had deep contradictions.

As Zhu Yuanzhang's father-in-law, Guan Duo immediately had a plan in his heart.

If Zhu Yuanzhang doesn't listen to orders in the future, Guan Duo will have another plan in his heart.

After leaving Haozhou, Guan Duo and his party came to Dingyuan.

As soon as they entered Dingyuan City, Guan Duo and the others found that Dingyuan City was very different.

At present, the Red Turban Army is uneven, but the military discipline is the same, and it is a little sloppy.

Every rebel army who occupies the city is eager to drink wine and eat meat every day, and live happily every day.

However, the rebel army in Dingyuan City is very different.

Not only were there no drunken and gambling soldiers on the streets, but not even idle soldiers were missing.

Guan Duo couldn't help but be impressed by the military discipline of the Dingyuan Righteous Army.

When he saw Li Shanchang, who was staying in Dingyuan, after some comparison, Guan Duo actually felt ashamed of himself.

Guan Duo called himself a wise general in the Red Turban Army, unlike those vulgar generals.

However, after talking to Li Shanchang, Guan Duo immediately found that his little knowledge was simply not worth mentioning in front of Li Shanchang.

In just two days in Dingyuan City, Guan Duo was very shocked in his heart.

He couldn't help but secretly think: "This Zhu Yuanzhang is definitely not simple!" I actually know how to restrain the people and win the hearts of the people, how many times have I persuaded the generalissimo to restrain the military law to win the hearts of the people, but it has not had much effect, this Zhu Yuanzhang's mind is not small! ”

"Not only this Zhu Yuanzhang, but also his younger brother Zhu Han, will not be a simple character, Li Shanchang's character, two out of three sentences refer to this Zhu Han, and he must be a powerful person."

During the two days of Dingyuan's rest, Guan Duo heard many rumors about Zhu Han.

From the well-known victory of the Red Turban Army to break through Haozhou and Dingyuan, to the saying that the miracle medicine in Dingyuan City broke the plague, and finally there were rumors that the assassination of Cheng Aru Gray in the Tartars of Except for the state, it seems that Zhu Han and others sneaked into the city to do it.

After hearing these rumors, Guan Duo's impression of Zhu Han couldn't help but become a little confused.

"Damn, this Zhu Han, is he a monster, he can be literate and martial, understand medicine soup needles, and be a fucking assassin, I have to see if he has three heads and six arms?"

Under the escort sent by Li Shanchang, Guan Duo and his party soon arrived at the city of Jiezhou.

As soon as they entered the boundary of the prefecture, Guan Duo and the others were overjoyed.

In addition to the prefecture's proximity to the south of the Yangtze River, the local water and soil already have the atmosphere of the south of the Yangtze River, which is very different from the drought-stricken Yingzhou area.

Many farmers in the farmland in Yingzhou are busy harvesting, and those golden rice grains are greatly envious of Guan Duo and others.

If they have this food, the Red Turban Army in Yingzhou will not only survive the winter, but may also take the opportunity to launch a wave of offensive and seize some territory.

When they entered the city of Jiezhou, Guan Duo and the others were shocked by the prosperity in the city.

Guan Duo and they can't remember how long it has been since they have seen such a bustling and lively street scene.

"It seems that there is no problem with asking for food."

Guan Duo immediately had confidence in his heart.

Since Zhu Yuanzhang occupies such a good territory in Except Prefecture, and takes out some grain to honor the generalissimo, it is not as simple as joking.

Who knows, when he saw Zhu Yuanzhang, Guan Duo's wishful thinking almost failed.

Guan Duo is Liu Futong's messenger, and Zhu Yuanzhang and Zhu Han naturally attach great importance to it.

After they received Li Shanchang's urgent letter, they immediately guessed the purpose of Guan Duo's visit.

It is nothing more than grain and grass or gold and silver.

Whether it was grain and grass or gold and silver, Zhu Han persuaded the elder brother not to agree.

They don't have enough to use themselves now, so how can they have extra to support Liu Futong.

However, if you don't give it at all, it's a bit too much.

After all, the main force of Liu Futong's Red Turban Army was at the forefront of resisting the counterattack of Meng Yuan's army, and without them in front of them, Zhu Yuanzhang and they would really not have developed so smoothly.

Therefore, when the two brothers saw Guan Duo, they were very polite and respectful in their attitude.

As soon as Guan Duo saw Zhu Yuanzhang and Zhu Han, he immediately judged in his heart.

"These two brothers are not ordinary people, they are quite heroic as the ancients said!"

Since he is a heroic figure, Guan Duo is naturally careful to deal with it.

After some politeness, Guan Duo first clarified the intention.

He adheres to the principle of bad news first, then good news.

first said the request of Liu Futong, the generalissimo of the Yingzhou Red Turban Army.

"Now the army is about to attack the Central Plains, and strive to recover Kaifeng within half a year, everything is ready, only the east wind is owed, and the marshal needs to support 200,000 stones of grain and grass!" Guan Duo said.

As soon as they heard this number, even if Zhu Yuanzhang and Zhu Han had already prepared in their hearts, they were shocked.

"What, two hundred thousand stones?"

Zhu Yuanzhang almost jumped up and scolded his mother.

200,000 stones, almost enough to make 100,000 troops eat and drink for two months!

The 70,000 army under Zhu Yuanzhang does not have so much food, where is the surplus grain to support Liu Futong in Yingzhou?

"Hehe, 200,000 stone grains and grass, if it is in Yingzhou or Haozhou and other places, it is indeed a lot, but for the state, it should not be much, right?" Guan Duo said with a smile.

Zhu Han immediately frowned, and immediately said: "Mr. Guan, you should also see that there is no new grain here in addition to the state, and the original grain and grass savings are far from enough for our army, if we support the generalissimo's grain and grass, we will not shirk, one or two thousand stones can always be squeezed out with gritted teeth, but if it is two hundred thousand, even if our army does not eat or drink, it will not be able to take it out." ”

The elder brother Zhu Yuanzhang nodded beside him and said next.

"Mr. Guan, we don't talk darkly, we really don't have food, if it's gold and silver treasures, we can give some, and if it is converted, we can also buy 100,000 grains."

Listening to the words of Zhu Yuanzhang and Zhu Han, Mr. Guan's nose was almost crooked in anger.

In addition to the rice fields all over the state city, he could see it clearly, how could he not even take out 200,000 stone of grain.

As for the gold and silver treasures, it made Guan Duo even more unhappy.

He has already decided that Zhu Yuanzhang and his brothers are pretending to be stupid with themselves, who doesn't know that the Central Plains is in turmoil, where no one has sold grain, even if there are mountains of gold and silver, they can't buy much grain.

"Marshal Zhu, we are all brothers of the righteous army, we are like brothers and sisters, talking about money is to see the outside, now the generalissimo only needs food, besides, this food is not borrowed in vain!" Guan Duo changed his words and replaced the original grain for nothing with borrowed food.

Although everyone knows that if this grain is lent out, it will definitely not be returned.

"Oh, what else is there to say?" Zhu Han said with some curiosity.

For Liu Futong and Guan Duo, the leaders of the Red Turban Army, Zhu Han, as a traverser, still has a great attitude of recognition.

If he could help them, on the premise of not harming his own interests, Zhu Han would still be very willing.

"It's not a secret, the generalissimo is very happy to know that Marshal Zhu will go down to the state again, and he specially ordered me to come to the state and make Marshal Zhu the king of the sun!" Guan Duo said loudly.

"What, the King of the Sun?"

When Zhu Yuanzhang heard this, he was stunned, and then he was happy.

This is a king!

From ancient times to the present day, it has been a great honor.

Zhu Yuanzhang thought, if he can be crowned the king, it is too good, within a radius of hundreds of miles, there are many marshals and generals of the righteous army from all walks of life, but none of them are crowned kings, if he seals the king of Yang, then the command will be justified, as for the matter of 200,000 stone grain and grass, in fact, if you try to squeeze it, it is not impossible to take it.

Just as Zhu Yuanzhang was thinking, he suddenly felt that his feet hurt.

The strength was so great that Zhu Yuanzhang's painful face twitched, and he stood up with a snap.

"No way!"

Zhu Yuanzhang reacted quickly, and immediately took the opportunity to shout.

With a kick just now, Zhu Han made some mistakes in judgment, and now he hurriedly said.

"That's right, Mr. Guan, this is not a request, we will not agree!"

When Guan Duo heard this, he was immediately surprised.

He continued to ask in disbelief.

"Marshal Zhu, this is the king, the king of the sun!"

Zhu Han preemptively said: "Mr. Guan, just because we are the king of the sun, we can't accept it, our brother is to kill the Tartar for the heavens, not to enjoy the blessings of the king, this king of the sun, my brother will never agree!" ”

The elder brother Zhu Yuanzhang also nodded immediately, "That's right, except for the King of Yang, we won't be able to be it, this marshal is very good." ”

Seeing that he had touched a nose of ash, Guan Duo had no tricks, and in the end he had no choice but to go back to the post house to rest first, ready to think about countermeasures and then come again.

After Guan Duo left, Zhu Yuanzhang immediately pulled Zhu Han and asked.

"Brother, that's the king of the sun, the king! Why not? ”

Zhu Han smiled slightly, "Brother, don't you know that this Yang Removal King has a price?" ”

"200,000 stone grain and grass, in fact, is not a lot, it's not that we can't get it." Zhu Yuanzhang said.

"Brother, it is precisely because of these 200,000 stones of grain and grass that this Yang Removal King can't even ask for it!" Zhu Han said.

Zhu Yuanzhang was immediately puzzled, and hurriedly asked: "What does this mean, tell us about it!" ”

Zhu Han then said: "Let's not talk about the 200,000 stone grains and grass, just talk about the title of the King of the Sun, it is a big pit!" ”

"What a big pit!?"

"Now Meng Yuan has begun to organize various regiments to train troops to fight back against the rebels, the real bloody battle has just begun, so many rebels, Meng Yuan is worried that he doesn't know where to start first, and in the end he must be the first to fight the loudest name, if anyone dares to be the king, it will definitely not be able to run."

"The rafters that come out are rotten first!" Zhu Yuanzhang immediately understood.

"That's right, that's the truth, brother, our strategy in the future, but we must keep three sentences in mind!" Zhu Han said very seriously.

"What three sentences?" Zhu Yuanzhang immediately asked.

"Build a high wall, accumulate grain, and slowly become king!" Zhu Han said with a serious face.

In one sentence, it is that the anti-yuan situation will become more and more difficult in the future.

Tyranny is a behemoth, although the ending is death, but the various counterattack methods before death are quite powerful.

Whoever suffers the main damage will definitely have to pay a heavy price.

"Build a high wall, accumulate grain, and slowly become king?"

The more my brother Zhu Yuanzhang pondered these three sentences, the more he felt that it made sense.

Finally, he slapped his thigh and said with great emotion.

"These three sentences are so right, let's take care of ourselves first is the most important thing, what is the king of Yang, isn't it just a bullshit name!"

"Haha, brother, what you said is so right, when we are strong, how can we still need Liu Futong to seal the king of Yang, whatever king you want, you can be the king, wouldn't it be more beautiful!" Zhu Han said with a smile.

"It makes sense, when it comes to our hearts, then I'll send someone to send Guan Duo back, and save him from making noise again!" Marshal Zhu said.

Regarding this method, Zhu Han said again.

"However, we are all rebels, and if we don't help them at all, it will be unreasonable to be reasonable."

"Brother, how are you going to help?" Zhu Yuanzhang asked.

"Since Liu Futong is short of food, then we will help him get some food soon." Zhu Han said.

Hearing this, Zhu Yuanzhang was immediately confused.

"Didn't you just say that you want to accumulate grain, and you won't get out of the 200,000 stone grain?" Brother Zhu Yuanzhang asked.

"Brother, I'm talking about helping Liu Futong raise grain and grass, but I didn't say that I was pumping grain here in Jiezhou." Zhu Han said with a smile.

"And what do you mean by that?"

"Although there is a shortage of food in Henan, but the Yuan army occupies the fortress, but it has already scavenged enough grain and grass, if the righteous army can quickly break through a few cities, so that the Yuan army has no time to burn the grain and grass warehouse, then a lot of grain can be captured." Zhu Han said.

"That's right, how do you do that?" Zhu Yuanzhang hurriedly asked.

The Red Turban Army fought in the Central Plains of Henan, except for the battles in the city, all of them relied on brute force to attack, in addition to the casualties were more serious, and often gave the Yuan army in the city enough time to burn the grain and grass treasury before the fall of the city.

"Support Liu Futong with a batch of new gunpowder, and then send someone to teach them to attack and blast!" Zhu Han said.

Who knows, as soon as these words came out, Zhu Yuanzhang's reaction was greater than hearing about 200,000 stone grains!

The elder brother Zhu Yuanzhang stood up and waved his hand vigorously.

"That's not going to work!"

"Brother, this is our ability to press the bottom of the box, how can we teach it to others?"

It is precisely because of the acupoint attack and blasting method that Zhu Yuanzhang led the righteous army to break through Haozhou and Dingyuan in only three days.

In the Central Plains of Henan, the soil quality there is more suitable for digging tunnels, and it is more suitable for cave attack and blasting than here in Huaixi.

"Brother, there has never been any invincible tactics, our acupoint attack and blasting is a trick that eats all over the world, if it is found out by the Tartars in the future, and then used for a surprise attack, it will definitely not work so well, it is better to teach Liu Futong them as soon as possible, let them make a bigger noise, the more they make trouble, the greater the loss of Meng Yuan, and the safer we are." Zhu Han said.

The power of cave attack blasting is indeed huge, but if the defenders intercept it with a tunnel earlier, the effect of surprise victory will be greatly reduced.

Rather than holding this tactic in your hands until it is outdated, it is better to let Liu Futong come to the Mengyuan court as soon as possible.

Under Zhu Han's persuasion, the elder brother Zhu Yuanzhang finally agreed.

As for who to send to be the master of this cave attack and blasting, it is naturally Zhou Dexing, Hu Yiba's identity as a tomb robber is too bad, and it is easy to be despised if he goes.

When Zhou Dexing knew this order, he immediately became excited.

"Marshal, don't you like this!"

"This is our top secret, how can we teach it to others?"

"If I resist the military order, I won't listen!"

In the face of Zhou Dexing's stubbornness, Zhu Yuanzhang couldn't cry or laugh.

Zhou Dexing, who has the title of Demolition Maniac, has long been ready to guard top secrets for the rest of his life.

It's good now, the Zhu Han brothers actually asked him to teach Liu Futong?

It's worse than killing him.

However, under Zhu Han's persuasion, Zhou Dexing finally changed his mind.

"Brother Zhou, let's fight the state, and we haven't had the opportunity to attack and blast for a long time, aren't you afraid that your skills will be wasted?"

"Let's take this opportunity to conquer a few more Tartar cities, kill more Tartars, and practice more skills."

"When the time comes, you will teach Liu Futong their old craft, and then you will have a better way through actual combat, isn't it better?"

In the face of Zhu Han's clever tongue, Zhou Dexing was naturally irresistible.

After all, this acupoint attack and blasting method was handed over to him by Zhu Han, and Zhou Dexing would not admit death too much.

When he saw Guan Duo again the next day, Zhu Yuanzhang told Guan Duo about this matter.

"What, Marshal Zhu wants to give me the method of breaking through the city wall quickly?" Guan Duo was surprised when he heard this.

In these years, even if he is a carpenter and has some ability, he is hiding and tucking it, and he can't wait to pass on the male to the female, and no male to bring it into the coffin.

Zhu Yuanzhang was good, and he actually wanted to call out the exclusive stunt, which couldn't help but surprise Guan Duo.

"Yes, if the generalissimo can have this method, he will definitely be able to occupy a few more cities and seize a large amount of grain and grass, otherwise we won't be able to get grain and grass, and we won't be able to help much, but it's a pity in my heart!" Zhu Yuanzhang said.

Seeing this, Guan Duo secretly said in his heart: Count your Zhu Yuanzhang still have a little conscience of being a righteous army, and there are several poisonous plans that I thought of last night, that is, I don't need to use it on you for the time being.

"In that case, let's go and see it, okay?" Guan Duo said immediately.

Zhu Yuanzhang glanced at Zhu Han next to him.

I saw Zhu Han smile slightly, nodded and said.

"Brother, Mr. Guan, I have ordered someone to get ready, you can go and see it at any time!"

"Haha, okay, go, go!" Guan Duo was already a little impatient.

An hour later.

On school grounds other than state towns.

Rumble!

With a roar, a thick cloud of dust shot straight into the sky.

By the time the dust fell, a huge gap had been broken in a section of the city wall.

"Mr. Guan, how is it?" Zhu Han asked with a smile.

Guan Duo did not give any answer.

He was already stunned by what he saw.

Even if the acupuncture blast just now is just a demonstration, whether it is in terms of distance or power, it cannot be compared with actual combat.

However, just like this, Guan Duo has already felt the destructive power of devastating.

With this acupoint attack and blasting method, it is no wonder that Zhu Yuanzhang can conquer Haozhou in three days and break Dingyuan in four days!

As soon as the tunnels were dug and the gunpowder was released, a section of the wall collapsed completely.

With such terrifying power, where is there a city that can re-enter the hundreds of thousands of troops of the Red Turban Army!

As long as there is no city wall to block it, Liu Futong's Red Turban Army does not want to seize any city, then take which city.

There is no need to worry about the lack of food and grass at all, it is enough to quickly attack a city and then snatch the grain and grass inside.

Unless the Mengyuan army saw the Red Turban soldiers approaching the city, they immediately burned the grain and grass warehouse.

Otherwise, as long as the Red Turban Army was given two or three days, once the cave attack and blasted the city wall, it would be too late for the dog Tartars to burn the grain and grass warehouse.

"Mr. Guan, Mr. Guan?"

"Mr. Guan?"

Zhu Yuanzhang and Zhu Han screamed several times before finally bringing Guan Duo back to his senses.

"Ah, oh, Guan is rude, rude!"

Guan Duo immediately apologized very politely, and then he asked in disbelief.

"Marshal Zhu, do you really want to give me this cave attack and blasting method?"

Zhu Yuanzhang nodded, "That's right, we have already demonstrated it just now, so naturally we want to teach it to Mr." ”

When Guan Duo heard this, he was immediately moved, his eyes were flushed with red light, and he secretly hated himself in his heart, he was still thinking about what bullshit and stumbling last night, he was so sorry for the loyal and courageous Zhu Yuanzhang brothers!

The ancients once said that it is better to teach a man to fish than to teach him to fish.

With this cave attack and blasting method, it is much more important than 200,000 stone grain.

200,000 stone of grain can always be eaten, and with this cave attack and blasting method, you can get as much grain and grass as you want.

Guan Duo immediately hurriedly asked: "Marshal Zhu, how to choose where to dig the tunnel, how to consolidate the tunnel, how to standardize the direction, how to bury gunpowder, how to lay the lead......

Guan Duo asked a lot of questions.

As soon as Zhu Han saw it, he knew that this Mr. Guan was really concerned, and every question was asked on the key point.

These professional problems are really a bit embarrassing for my brother Zhu Yuanzhang.

Zhu Han stood up and said, "Mr. Guan, these things can be learned in actual combat after you go back." ”

When Guan Duo heard this, he was immediately pleasantly surprised.

"What do you mean by the deputy marshal, do you still want to send me someone to teach me by hand?"

Zhu Han nodded, pointed to Zhou Dexing next to him and said.

"This is our old brother Zhou Dexing, if you want to say that this cave is attacked and blasted, Brother Zhou said second, no one dares to say first!"

When Guan Duo heard this, he immediately looked at Zhou Dexing like a baby.

He grabbed Zhou Dexing's arm, as if he was afraid that he would run away.

"Brother Zhou, I am eating and sleeping with you today, but I can't let you run away!"

Zhou Dexing enjoyed such an attitude of importance, anyway, Zhu Han had already told him, and he would teach Zhou Dexing better and more powerful siege methods in the future, and his current task was to follow Guan Duo to Liu Futong's army and help Liu Futong create an engineering team, which was specially used to plague the Mengyuan court in the north.

Historically, Liu Futong circled around Henan for several years before he finally broke through some important cities.

Important cities such as Bianliang were not breached until five or six years after the uprising.

Zhu Han just wanted to help Liu Futong and make the momentum of the Northern Red Turban Army as loud as possible.

The more powerful the Red Turbans were, the safer they were in the state.

As the demolition maniac Zhou Dexing followed Guan Duo and his party to Yingzhou, Zhu Han and his brother Zhu Yuanzhang also firmly established the route of 'building a high wall and accumulating grain to slowly become king' in Zhuzhou.

As the saying goes, warriors are the best city walls, and the first step is to train soldiers and horses.

The elder brother Zhu Yuanzhang led Xu Da and others to train the main force according to the old way.

And Zhu Han took Lu Zhongheng, Hu Yiba, Chen Baodao and others to train more than 3,000 new troops.

said that it was a training for the new army, but Zhu Han didn't go to the school every day recently, but soaked in the newly established workshop all day long.

In the last few check-in rewards, Zhu Han has obtained some of the most critical technical books, which can be used to solve the manufacturing difficulties of muskets and artillery.

He now stares at the armory workshop every day, just to be able to make qualified muskets and cannons one day earlier.

After many days of cyclic testing, the Except State Workshop finally made a qualified guncopper.

This specialized bronze made it possible to create the most powerful breech gun.

Because of the high price of copper and the scarcity of raw materials, in order to cast copper cannons, Zhu Han purchased almost all the bronze artifacts in the city except Zhouzhou, and finally barely scraped together enough raw materials to cast ten cannons.

After some comparison, Zhu Han made the final allocation plan for casting artillery.

As soon as he arrived at the armory, he immediately found the craftsman in the workshop.

"Lieutenant Marshal, what are your orders?" An honest and honest middle-aged craftsman asked as he walked through the door.

Zhu Han's current position is still the secretary of the Marshal's Mansion, but everyone likes to call him the deputy marshal, and after several attempts to change it to no avail, he let it go.

"Zheng Kelu, this is the cannon casting square I made, and you can make it according to this." Zhu Han took out a stack of drawings and handed them to the middle-aged craftsman.

The craftsman of the weapons workshop in front of him, that is, the chief craftsman, was originally a craftsman household of the Mengyuan Imperial Court in Zhuzhou, specializing in casting things such as Buddha bells.

According to the principle, if you can cast a large bronze bell, you will master the technology of casting bronze artillery.

Therefore, Zhu Han did not hesitate to promote this craftsman named Zheng Qiwu.

and also gave him an auspicious new name, Zheng Kelu.

With a generous salary of three taels of silver and three hundred catties of rice per month, Zheng Kelu and other craftsmen worked hard.

"Two ten-pound guns, three eight-pound guns, five three-pound guns, gun carriage ......"

Zheng Kelu can read simple words, which is also an important reason why he can work as a craftsman.

"How's it going, is there a problem?" Zhu Han asked beside him.

The blueprints for these breech-pound guns were taken from the twelve-pounder, nine-pounder, and three-pounder guns that had been fought in actual combat in later generations.

The so-called pounds or catties are calculated by the weight of the solid bullet fired, the higher the weight, the greater the power of the gun, and the higher the cost is naturally required.

"Adult, villain thinks there is no problem, you can open the furnace and cast at any time!" Zheng Kelu said with great confidence.

Now in the arsenal, the iron mold for casting the copper cannon has already been prepared, and it only needs to melt the copper water and then cast it, which is far less than half of the time compared to the original clay mold casting cannon.

Zhu Han has repeatedly come up with all kinds of whimsical methods, which has already made Zheng Kelu and others as fairy-like characters.

What's more, the salaries and rations given to them by the rebels were very rich, far better than being slave craftsmen under the Mongols, so they naturally worked hard with all their hearts.

In just three days, a total of ten guns were cast.

All that remains is to polish the inner wall of the gun so that it is smooth and unobstructed.

Craftsmen such as Zheng Kelu originally used small manpower machines to polish the inner walls.

After Zhu Han saw it, he decisively ordered the transfer of tens of thousands of catties of pig iron to build a simple boring machine that uses hydraulic power, which immediately greatly improved the efficiency.

In just half a month, all ten artillery pieces were produced.

However, compared to artillery, the manufacture of muskets was difficult.

Muskets must be made of steel, and it is much more difficult to create a good barrel.

Zhu Han provided many improvements, and the scrap rate of the musket was still as high as six or seven percent.

This results in a huge amount of money and poor results.

When all ten cannons had been cast, less than five hundred muskets were made, which cost more money.
