West of Tokyo, on the side of the barracks.

When Zhao Huan hurriedly led people over, he saw a person lying on the ground, his flesh and blood were blurred, motionless, and Ling Zhen was watching with a few people with a pale face.

People died.

Next to the corpse was an iron pipe that had burst a large hole.

With Zhao Huan's knowledge, he immediately understood what was going on.

"Your Highness......"

Ling Zhen came to Zhao Huan dejectedly.

Zhao Huan comforted: "Although the bore was blown up and a brother was killed or wounded, it at least proves how powerful your improved gunpowder is." ”

Zhao Huan pointed to the corpse on the ground: "Ten times more sympathetic to his family, if his family has any difficulties in the future, just tell the imperial court, or find Song Gongming!" He didn't die in vain, and Da Song won't be sorry for him! ”

"Understood!"

Ling Zhen and the others listened to Zhao Huan's words, and their faces were much better.

It's not that I don't care about the tenfold pension, people are already dead, and even if they are a hundredfold pension, they can't survive.

What they care about is Zhao Huan's attitude, and the sentence "Da Song won't be sorry for him" made everyone present excited.

Sometimes the recognition of the superior is even greater than the effect of real money.

Ling Zhen waved his hand and asked people to carry the body down, buy a coffin to put it up first, and then take the body away when their family members arrived; When Zhao Huan heard this, he gestured to Yu Baosi, who took out fifty taels of silver and handed it to Ling Zhen's men to buy a coffin.

This coffin was bought by Zhao Huan.

Zhao Huan picked up the iron pipe on the ground, looked at the hole that was blown open by gunpowder, and said:

"It's not gunpowder, it's iron! The iron pipe made of iron liquid inversion is too brittle to withstand this kind of strong gunpowder, so let's use copper pipe for the time being, and thicken it at the same time! ”

"Your Highness, please look over there!"

Ling Zhen nodded, pointing into the distance.

It was something the size of a hut, covered with a big red cloth.

"That's a bronze cannon cast according to His Highness, weighing five thousand catties! If all copper is used, it will cost too much, and in the future, it may not even be able to guarantee the minting of copper coins in the imperial court. ”

The size of the hut turned out to be a bronze cannon!

Zhao Huan shuddered for a while.

No wonder the cannons of the Ming and Qing dynasties were generally used to defend the city, and the 5,000-pound copper pimple was indeed inconvenient to transport, and it was more convenient to put it at the head of the city.

Thinking of this, Zhao Huan suddenly had an idea about defending the city in his mind: With such a copper cannon, coupled with the fierce fire oil tank, it is not easy to defend a city or a checkpoint?

Once this idea is bred and deeply rooted in his mind, in the future, when he fights against Liaojin, he will inevitably encounter offensive and defensive battles.

However, he still hoped that the bronze cannon would be smaller, and as long as it could be transported by horse-drawn carts, it could be used to siege the city.

He pointed to the huge bronze cannon and asked, "If the amount of gunpowder is reduced, will this cannon be smaller?" ”

Ling Zhen shook his head: "If the amount of gunpowder is insufficient, the iron pellet will not be able to fly that far, and it will lack strength." In fact, at the beginning of the founding of the Great Song Dynasty, there were already copper cannons of the same size as His Highness said during the Taizu period, which used the previous gunpowder, but the amount was very sufficient, but the cannonballs were not far away, so they were only used as cannons. ”

"But this bronze cannon we cast is different, we just cast it last night, we have tested it a few times, with a sufficient amount of new gunpowder can shoot a huge cannonball five hundred zhang away, no matter how strong the city gate is, it only needs one shot!"

Five hundred zhang away, it has been more than 3 miles.

With such a long range, no matter how powerful a trebuchet can throw such a far, it is indeed unprecedented.

"If you change to a smaller cannonball, will you be able to use a smaller cannon?"

"That's true!" Ling Zhen said, "If it's small enough, it's a firecracker, but the distance and power are very limited, and it's not very useful." ”

Zhao Huan looked at the exploded firecracker, and suddenly another thought flashed in his mind, and he hurriedly asked: "The cannonballs you are using now are all solid, and if they are small, their power is naturally limited; But if the shell is made hollow, filled with explosives, and only a small mouth is left to plug the oil rope for ignition, so that the shell is shot out not to kill people but to blow people up, can it be realized? ”

Zhao Huan remembered that the cannonballs that could explode first appeared in the Ming Dynasty, called sub-mother cannons, and I don't know if they can be studied in this era.

Sure enough, Ling Zhen's eyes lit up when he heard it, and then he frowned and thought hard.

This difficulty is not ordinary, and there are many places to overcome, such as the amount of gunpowder, the thickness of the shell, the length of the oil rope, and the time of ignition.

"Even we can just study this bomb and throw it with a conventional trebuchet, which is more feasible! If you hide this bomb and make it into a trap, it is also very powerful, and it will be very advantageous to use it as an ambush! Zhao Huan reminded again.

That's a landmine. What is lacking in this era is brains and insight, as long as there is a direction, it will not take long to gain with the strength of Ling Zhen, a skilled craftsman in the Great Song Dynasty.

"Although this matter is urgent, I also know that I can't rush it! You are studying the cannonballs here, and I will ask Tanglong to send someone to study the iron pipes, and you both will do it at the same time, so it will be faster! Thank you! It's important to stay safe in the future, you and everyone under you are precious! ”

Zhao Huan saw that Ling Zhen was still deep in thought, and quietly left with someone.

The development of firearms has been another setback.

Of course, the original guys are not useless. A hundred cannons are fired at once, and no matter how powerful the master is, he can't stop it; Unfortunately, the power is too small, and the shells are inconvenient to fill, as long as the opponent has enough numbers, it can only fight one round and bring hundreds of casualties to the opponent, which is of little use for a major battle.

Must continue to study, Zhao Huan considered increasing the personnel and expenses on Ling Zhen's side to improve the progress.

If he couldn't research out the new guns and artillery, Zhao Huan would not be much sure about destroying Xia, Liao, Jin, and Meng.

It seems that this time the conquest of Wang Qing can not be counted on.

Zhao Huan looked up at the weeping willows on both sides of the road, and there was already a little green on the willow branches.

The time has come to go on the expedition.

……

Whoosh –

As soon as Zhao Huan entered the harem martial arts arena, a sword light flew over, followed by a powerful and heroic girl.

Wow –

Zhao Huan also pulled out his sword with a smile and performed the Qingfeng Sword Technique.

It seems that his talent in martial arts is not bad, after a hair cutting and marrow washing, a rebirth, with the support of the Immortal Sutra Xuan-level Ninefold, it is only a month and a half of hard practice, and his Qingfeng swordsmanship is no longer what it used to be.

Qingfeng swordsmanship is different from Chen Liqing's swordsmanship, its biggest feature is that it does not see the sword light, and it is like a breeze blowing on the face, and the opponent has reached the key point unconsciously, which is a typical "pretending to be a pig and eating a tiger" style exercise.

Zhao Huan's biggest flaw at present is that he will not hide his murderous aura, he is easily alerted by his opponent, and he cannot bring out the true essence of Qingfeng swordsmanship.

Therefore, among all the people, only Liu Huiniang practiced the Qingfeng swordsmanship the best, and she was the only one who entered the realm faster than Zhao Huan, compared to Shi Jin.

Only Chen Liqing is the worst, this female tyrannosaurus has practiced for two or three months without making any progress, so she has to give up, and now she is raiding Zhao Huan, using her own swordsmanship.

After a dozen moves......

Chen Liqing put away her sword and laughed coquettishly.

"You've lost! But this time you actually dodged my sneak attack, and also avoided my next fifteen moves in a row, so that I defeated you on the seventeenth move, although it is not as good as Hui'er, but the progress is still great, keep up the good work! ”

Zhao Huan returned the sword into the sheath and said with a smile: "Hui'er can take your urgent move?" ”

"Twenty-nine moves! This Qingfeng sword technique is simply tailor-made for Hui'er, although I finally defeated him, but there were several times when I almost touched her way, there was always a feeling that she wanted to greet me, but when I woke up, I found that the tip of her sword was almost on my clothes. ”

"That just shows that she has no killing intent towards you in her heart, so she will show her flaws; If you really want to kill someone, Hui'er will have no flaws when she uses the Qingfeng Sword Technique! This is indeed better than us! ”

Zhao Huan stepped forward to tire up Chen Liqing's somewhat wrinkled clothes affectionately, and brushed the sideburns in front of her eyes behind her ears.

"But if I use a halberd, whether you use a sword or a gun, I can hold at least thirty moves!"

Compared with the Qingfeng Sword Technique, the Overlord Halberd Method is much more powerful and rigid, which is more suitable for Zhao Huan's cultivation and more suitable for going to the battlefield.

What's more, the Overlord Halberd Method is the ultimate exercise, which is not only easy to get started, but also can be advanced and broken through, endless, enough for lifelong cultivation.

"Hmmm! The talent of the officials is still very good! ”

Chen Liqing praised unabashedly.

Zhao Huan pointed inside: "How are the female guards under your subordinates cultivated?" ”

"Most of them can only pick me up for three or five moves, and some of them can already pick me up for five or six moves, which is also very good, after all, it's only been a month and a half, not everyone is as talented as Prince Song, isn't it?"

"I can only pick you up three or five times?"

Zhao Huan was slightly disappointed.

"Hey! Don't underestimate them, and don't underestimate me, okay? Few of the soldiers defending the city can catch me with more than two moves! ”

Zhao Huan was overjoyed: "So powerful? ”

"Of course!"

Chen Liqing said bluntly, her little face full of pride.

There is indeed a capital of pride!

It's only been a month and a half, and a group of palace maids can be trained into qualified guards whose average strength exceeds that of the forbidden army sergeants, which has a lot to do with Liu Huiniang's strict requirements, and Chen Liqing's own strength and dedication to teaching.

"Qing'er, do you want to go into battle to kill the enemy?" Zhao Huan looked at her and smiled.

Chen Liqing's eyes lit up, and she said hurriedly: "It's decided?" When to go? You must take us there, official, this palace is suffocating! ”

"That's nature! In this way, you secretly ask everyone to get ready, don't make a noise, and let's set off quietly in three days! ”

"Good!" Chen Liqing said happily, "I'll let everyone get ready!" ”

Zhao Huan hurriedly said: "It's not everyone, you have to leave some guards Lian'er and Xuan'er, they often go to the inner city and the outer city to inspect, and they can't be without close protection." ”
