Puyang River, Shaoxing Prefecture, one of the three major rivers in the southeast, is the river of the ancient Yue Xi Shi Huansha sinking fish, the perennial water surface width is more than 100 meters, and the water flow is turbulent.

In the west of Huiji Mountain, next to a ferry on the bank of the Puyang River, there was an abandoned shipbuilding workshop, and I don't know when a new workshop was built. The fence runs from the river to the workshop, and there are signs on it that read, "Military Stronghold, No Idlers" and "No Fireworks". In addition, the officials with guns and knives are eyeing each other, and idlers from near and far subconsciously avoid it.

The officials are all transferred from the county government of Huiji, and the board of directors of the county is personally selected. In this regard, the board of directors has a lot of support.

Several huge waterwheels waded through the water, driven by the boiling river water, and the crankshaft drove the mills on the bank, and the black gunpowder was crushed back and forth. Tian Yi stood aside, spraying rice soup from time to time, and constantly pinching his hands to figure out the hardness.

After a while, the rolled gunpowder is poured into a bamboo sieve, continuously squeezed into small pieces by hand, and then rounded by rolling, which is granulated gunpowder.

75% fire nitrate, 10% sulfur powder, 15% charcoal powder.

This is the recipe that Zhao Hong told him about explosive gunpowder.

A little more fire nitre, a little less sulphur powder and charcoal powder.

This is what Zhao Hong told him about the recipe for artillery propellants.

Zhao Hong opened his mouth, but he broke his leg. Fire, sulfur, and charcoal, he had to do it himself. In the past two months, he tried again and again, and he felt annoyed to death, but suddenly found that he was enjoying it.

Fundamentally, he is a bold and careful person, but also a person who wants to do things.

It's a lot more fun than selling meat!

"Dad, bring the box!"

Tian Yi said to his father.

The development of gunpowder is more secret than iron smelting, and one person is too busy to do it, so he can only take the blessings to make up for it.

When his father Tian Shouxin brought the ruler-long iron box and laid the fuse in the rectangular iron box, Tian Yi carefully packed the gunpowder, the fuse stretched out of the box, and then covered the iron lid.

"Let's go! Go for it! ”

Tian Yi picked up the iron box and walked out of the workshop.

"Will this work? You're a pig killer! ”

Tian's father looked incredulous.

"What's wrong with killing the pig, you didn't force it?"

Tian Yi said dissatisfiedly, his eyes lit up.

"This time, I, the pig killer, will be named in Ancheng!"

Speaking of which, gunpowder was not Zhao Hong's idea, he just did it.

"Blow you!"

Tian Shouxin shook his head and followed closely.

However, if it weren't for his straightforward nature and his lack of wanting his son to serve in the army, his son would not be a meat seller.

"Cover your ears!"

Tian Yi shouted at the guards.

"Peng!"

The explosion was earth-shattering, the earth and rocks were flying, the earth wall was blown up, and the guards of the iron mill lowered their hands, their ears were buzzing, and everyone was dumbfounded.

It's the first time I've seen explosive gunpowder that is so ferocious.

Tian Yi got up from behind the stone where he was hiding, and walked over to look at the rubble and iron fragments all over the ground.

"Oh my God! What a murderous weapon! If this is made into earth-shattering thunder, there is no need to worry about defending the city! ”

Tian Shouxin picked up a piece of broken iron, his face turned pale, and his heart was pounding.

The power of this gunpowder is much stronger than that of the army!

"Good!"

Tian Yi was pondering whether the gunpowder could still be improved, Zhao Hong clapped his hands, smiled with a smile on his face, and walked over with Xu Sheng and a few guards.

"Your Highness!"

Tian's father and son stepped forward to salute together.

"Tian Yi, listening to the voice, I think it's almost!"

Zhao Hong looked at the iron and stone fragments all over the ground and nodded slightly.

It may not be as good as the explosives of later generations, but it should be higher than this era.

"Your Highness, whether it's the formula of gunpowder or granularization, I think we can try it again and improve it again."

Tian Yi told the truth. Listening to the sound, he felt as if the explosion was not so transparent.

"Okay, try slowly, don't rush."

Zhao Hong nodded.

Science and technology, the foundation of industry, can succeed casually.

"How's the cannon casting?"

Zhao Hong asked subconsciously.

"Your Highness, it may take a while. Now that the ironmaking has just stabilized, I'm looking at how to cast the cannon with the craftsmen and make the mold first. ”

Tian Yi pondered and said.

The assault guns that I used to make were all small tubes, and they were all easy to say. The current artillery is seven or eight hundred pounds, and it is not so easy to require the chamber to be straight and slippery.

"Don't rush, take your time. That earth-shattering thunder is simpler, take the time to take a look, and make it first. ”

"Your Highness, the Heaven-Shaking Thunder is simpler, and it should be possible to make it first. Before the Qingming Festival, I tried the gunpowder first. By April or May, it should be possible to make the earth-shattering thunder. ”

Tian Yi said with a sigh of relief.

Zhao Hong nodded. When the time comes, Shi Miyuan will see that if there are hundreds of earth-shattering thunderbolts smashed over, thousands of troops will not pay attention to them.

"Qingming Festival? Then you better go back and come back after the holidays. ”

Zhao Hong was stunned and shook his head again and again.

The Qingming Festival of the Song Dynasty is a big festival, and the same as the Yuan Xi Festival, the official has to put a seven-day holiday, planting willows, sacrifices, walking green, dragon boat racing, etc., which is very lively.

Tie others here for the big holidays, and don't have three times the salary, how can you bear it?

"We'll see. Your Highness, you should go back to Lin'an City to do your own business! Here are me and Li Tang. You can rest assured. ”

Tian Yi instead urged Zhao Hong.

"Okay, okay, you get busy first. I'll go to the ironshop to have a look, and then I'll go back to Lin'ancheng. ”

Arida Yi stared, Zhao Hong really had nothing to worry about.

"This Zhao Hong seems to have changed as a person!"

Tian Shouxin watched Zhao Hong and the others beat their horses away, shook his head, and looked incredible.

"Awesome! Is it blinding you...... Eye! ”

Tian Yi said in a letter, and the word "dog" almost blurted out.

"If he really has the ability, he will become the prince as soon as possible. If he becomes a Great Song official, I will go to the front of the palace to serve him! ”

Tian Shouxin didn't know whether it was true or not, and sighed leisurely.

"Definitely! Dad, you, the head of the forbidden army, are decided! ”

Tian Yi smiled, with indescribable calmness in his eyes.

At the foot of the mountain, on the official road, Li Tang came by horse, and several carriages behind him were loaded with dozens of bags of fluorite powder, which he had just received from the Ministry of Industry.

The people from the Ministry of Industry did not trouble him, but were polite and responsive, which surprised him a little.

I don't know what kind of medicine these Shi Miyuan's echo worms sell in the gourd.

In front of the iron workshop, Li Tang tied his horse, and looked at a few high-headed horses tied to the gate, and couldn't help but be stunned.

"Big head, who is that? Why did you still enter the yard? ”

Iron smelting is an important weapon of the country, and Zhao Hong has confessed to keep it secret. Are these uninvited guests officials of the imperial court?

"Second brother, it's the master and servant of the shopkeeper Yan, and I've been here for a while."

Hu Datou said with a smile, secretly envious in his heart.

It's still His Royal Highness who is powerful, so that the beauties rush to deliver things to the door.

"You are bold! How did you let her in? You don't know, it's a military ...... Heavy land? ”

Hu Datou was furious and glared at Hu Datou.

If this iron-smelting technology leaks out, Zhao Hong must be the finger of Qianfu, and he, the leader of the guards, can't eat and walk around.

"Second brother, the shopkeeper of Nayan and His Royal Highness Qingqing and mine, a good pair. I'll just ......"

Hu Datou was submissive, and he also felt a little reckless.

"Nonsense! How can she be worthy of His Highness! I don't care about you! ”

Li Tang brushed his face away from Hu Datou, walked a few steps and stopped.

"Go quickly, go to Tian Dalang! Tell him that if Yan Chun comes, let him not show Yan Chun anything! What to see, go quickly! ”

Li Tang told him sharply, Hu Datou woke up like a dream, and quickly led the horse out of the gate of the iron mill and left.

"This stupid ......"

Li Tang quickly stepped into the ironshop, strode forward, and just saw Yan Chun with his servants open, looking around the iron-smelting furnace, it seemed that he was about to enter the ironworkshop.

And Zhang Hong, who was guarding the gate of the iron workshop, looked at Yan Chun and the others with a smile, nodded and bowed, and seemed to have no intention of stopping him.

Li Tang took a few steps forward and blocked in front of Yan Chun and the others, he glared at Zhang Hong, who was confused, and turned his head with a black face.

"Shopkeeper Yan, what are you going to do?"

From beginning to end, he felt that this Yan Chun was eccentric, arrogant and rude, and he was not a good match for Zhao Hong.

Yan Chun was about to enter the iron workshop, but was stopped by Li Tang, and couldn't help but raise his eyebrows.

"Get out of the way! Where is Zhao Hong? My master is here for him! ”

Zhang Kai observed his words, and immediately stepped forward and scolded Li Tang.

A small guard, who dares to be rude to his master, is simply looking for death.

The craftsmen in the iron workshop, including Zheng Hao, all looked at all this in amazement.

"I'm sorry, this is a place where weapons are heavy, and idle people are not allowed to enter! His Highness has gone to other places, not here! ”

Li Tang replied with a dark face, there was no room for bargaining.

"Bold! You dog minion, I'm here to find Zhao Hong. Get out of here! ”

Miscellaneous people, etc.?

Yan Chun's fire suddenly came out.

When, what cats and dogs, dare to blow their beards and stare at her.

"Shopkeeper Yan, your mouth is cleaner! Don't let people look down on you! ”

Li Tang said with a dark face, and Zhang Hong on the side unconsciously stood up straight.

Looking at Li Tang's posture, it seems that he is not dealing with Yan Chun.

Why is that?

The horse he rode was still given by Yan Chun!

"You dog-like pickles! Look for death! ”

He stretched out his hand and drew the knife from his waist.

"Want to play with your life? You try! ”

Zhang Hong snorted, immediately pulled out his knife, and blocked in front of Li Tang.

He knows who he is. When playing with his life, he doesn't back down.

"That's it! Put all the knives away! ”

Yan Chun retreated and stepped forward.

"Li Tang, get out of the way! I'll go in and find Zhao Hong by myself! ”

"I'm sorry, Shopkeeper Yan, Your Highness is not here. I repeat, this is the Ordnance Division, don't enter the idlers. Otherwise, don't blame me for turning my face! ”

Li Tang was unmoved, stretched out his arm, blocking Yan Chun's way.

Zhang Hong looked at Zhang Kai coldly, with a posture of being singled out at any time.

"Shopkeeper, let me kill him!"

Zhang Kai was furious, and he was about to draw his knife and step forward, but was stopped by Yan Chun.

"Forget it! Get back! ”

Yan Chun's face sank like water, she turned around and walked away.

"Shopkeeper Yan, I'm sorry. Slow down and don't send! ”

Li Tang bowed behind him.

"Second brother, what are you doing here? The shopkeeper Yan is good, you also have to look at His Highness's face. ”

"You idiot!"

Li Tang kicked Zhang Hong angrily.

"Remember, no one can enter the ironworks without my permission, let alone look east and west! This is what His Highness has confessed, do you remember? ”

Don't say it's Yan Chun, even if it's Shi Miyuan and Hu Yu, without Zhao Hong's permission, they don't want to enter.

"Zheng Yuanwai, you remember! The ironshop is now a forbidden place, and not everyone can enter! ”

Li Tang solemnly advised, and Zheng Hao hurriedly nodded yes.

The ironshop has become a forbidden place, and I am afraid that it will soon be no longer my own.

"Dad, come over here. I think it's better to use sand molds to cast cannons! ”

Zheng Hao's son Zheng Tu, who was tall and fat, like a mountain, pulled Zheng Hao in.

This Zheng father and son are both experts in iron smelting.

Li Tang nodded secretly, his eyes swept to the official road, Zhao Hong, Xu Sheng and others came over, and Hu Datou was also listed.

"Li Tang, well done!"

Zhao Hong said softly, obviously already knowing about Yan Chun's visit.

"Everybody's worked hard. On the Qingming Festival, you take turns on duty to avoid people peeping. Each person will be given 20 yuan for the holidays, which can be regarded as my heart. ”

Yan Chun came here to look for him, he shouldn't have come to see him on purpose.

He is self-aware, and he also thinks that he is not so charismatic.

Why does a beautiful girl have to go into the messy and hot iron workshop? Why are you so interested in iron smelting?

Zhao Hong shook his head, his heart full of confusion and confusion.
