Li Yunze was originally unwilling to get firearms.

It is simply that in the era of classical cold weapons, there were muskets and cannons or something, which was too discordant.

But after learning mathematics, physics and chemistry (basic), Yingzheng gradually approached the direction of science and engineering men.

In particular, he was most interested in gunpowder, and if it weren't for secrecy, he would have used it in the Kwantung countries a long time ago.

As the saying goes, 'The king of Chu has a thin waist, and he starves to death in the palace'.

What is good at the top will be very bad at the bottom. Since the king likes this kind of thing, there are naturally people who are willing to study it, so as to please the king.

To Li Yunze's surprise, the disciples of the Mo family actually did this.

After thinking about it for a moment, Li Yunze bluntly asked, "What does the king want?" ”

"Ugh"

Ying Zheng was asked, he had never been exposed to relevant knowledge, so naturally he couldn't imagine what a cannon would look like out of thin air.

He walked around a few times in distress, and finally said, "According to Wu He's meaning, it is best to make two tripods, one large and one small." The big giant tripod is the platform, the small giant tripod is the set, and an iron ball is placed in it."

Li Yunze understood after listening to two sentences, isn't this just a casing.

And Juding or something

"Forget it."

Li Yunze waved his hand: "I'll come." ”

Ying Zheng was overjoyed and saluted, "Then please leave it to the Taifu." ”

"That's right." Before leaving, Ying Zheng said, "The queen mother misses the queen very much, if you have to be free, you will ask the queen to go to the queen mother to give a lecture." ”

'Pulp.'

What else could Li Yunze say, he could only smile and nod his head.

For the big toys named by Ying Zheng, Li Yunze also did it with his heart.

After all, if this thing is not done well, it is very dangerous.

He also knew very well that with Yingzheng's character, if he really wanted to come up with artillery, he would definitely use it on the Kwantung countries first.

So I cast the redcoat cannon first.

The so-called red-coated cannon is actually called the Hongyi cannon.

The so-called Hongyi refers to the Dutch, the red-haired Dutch.

Later, he said that he was red, because the Ming court attached great importance to this big killing weapon, and tied a red ribbon to each cannon.

The prototype was a 12-pound or even 18-pound smoothbore cannon.

For Li Yunze, he has technology and experience, and all he needs to make it is time.

While Li Yunze was busy making red-coated cannons, the nomadic tribes on the northern grasslands suffered an unprecedented terrible blow.

The Qin State sent troops to the Western Regions, severely damaged the Yue tribe, and captured tens of thousands of its troops. Hundreds of thousands of cattle, sheep and horses were seized.

The herdsmen of the Yue Clan, who didn't even have a saddle, were hit by dimensionality reduction with weapons such as wooden sticks, and lamented that they had encountered monsters.

Soon, however, there were like-minded people.

The Donghu tribes located in the east also suffered a heavy blow from the Zhao State during the same period.

Li Mu went out of the fortress to break the Donghu tribes, and forced Lin Hu and other tribes to surrender to the Zhao State.

Nearly 100,000 people were killed.

The remnants of Donghu fled far away and did not dare to approach the Great Wall.

The Huns, who were only a vassal tribe under the command of Donghu, witnessed the decline of Donghu and began to annex small tribes and gradually grew stronger.

Li Yunze didn't listen to what was going on outside the window, and only did his own thing.

After the production of the red-coated cannon was completed and the test firing was successful, he arranged for people to go to Xianyang City to send a letter to Yingzheng.

A few days later, Ying Zheng, who was in high spirits, rushed to the place with a large number of people.

The test firing place is still the previous mountain ridge valley, in other words, in this place in northern Shaanxi, there are too many mountains and valleys like this kind of ditch and valley.

The valley is usually very deep and long, and in many cases there may be only a distance of more than 100 meters between the two mountains, but because of the existence of the valley, it is not uncommon to be unable to reach the opposite side for most of the day.

"Taifu."

Ying Zheng brought a young man to Li Yunze and introduced, "This is Yan Dan, the prince of Yan Kingdom." Some time ago, the sunrise envoy to Daqin. ”

Envoy Daqin or something, this is all good and obedient words to save face, just listen to it, don't care.

Prince Dan actually came here to be a hostage.

After all, Yan Guo was now beaten badly by Zhao State, and he urgently needed Qin State's help, so he had to send heavyweight hostages for help.

Li Yunze looked at the young Prince Dan, who was undoubtedly a very aristocrat who was very in line with the characteristics of this era.

It's just that his eyes are a little heavy, and even the smile on his face looks a little empty.

Regarding the direct mastermind of 'Jing Ke's assassination of Qin', Li Yunze just nodded his head, and didn't care too much about it after saying hello.

There are too many historical celebrities he has seen, and he has long passed the stage of excitement when he sees the person who left his name in the history books.

On the contrary, it is Prince Dan here, who is obviously very interested in Li Yunze, the mysterious Taifu.

not only circled around Li Yunze, but also kept asking Ying Zheng for news about him.

Unlike the King of Qin, who was suppressed by Lü Buwei at this time in history, and the queen mother Zhao Ji found a wild man, so that his personality gradually became cold under the great humiliation and suppression, Yingzheng at this time took the power into his hands early, and the queen Zhao Ji also kept to himself and did not drag him back, and the national strength of Great Qin was thriving and opened up a huge territory through the westward expansion strategy.

At this time, Ying Zheng's mentality and personality are much more sunny, and he has a very good attitude towards Prince Dan who is of the same age, especially the same disease who has been a proton, so that he has a very good attitude towards Prince Dan, and even treats him as a friend.

Even if it was a test firing of the big killer weapon that Taifu said, he was willing to bring it with him.

Regarding Prince Dan's investigation, Yingzheng didn't feel that there was anything to hide, he said everything he could say, and he said a lot what he couldn't say.

As for the white paper, printing, zigzag plough, cocoon and so on, Prince Dan has also seen it with his own eyes after coming to Xianyang City.

Of course, such as the cavalry three-piece suit and black powder, Yingzheng naturally won't say it.

As for this time, it was because Ying Zheng himself didn't know what Li Yunze had come up with, and he thought it was a giant ding, and he didn't have a sense of secrecy from relevant parties at all.

Even if it was just what he said, it had already shocked Prince Dan extremely much.

After learning that these things were actually all from Li Yunze's hands, Prince Dan looked at Li Yunze's gaze and changed uncertainly!

Because of the improvement of the quality of steel, the red-coated cannon cast by Li Yunze is not as heavy as the original, but it also weighs more than 1,000 catties.

He also equipped the redcoat cannon with wheels, wheels with steering shafts, as well as valves, ground hoes, crosshairs, and other improvements.

"What is this?"

Li Yunze, who was busy placing the artillery, heard the sound of inquiry coming from behind him, turned to look over, and said to Prince Dan with a curious face, "This is Dagui, also known as Qin Wang Cannon, and it is a ritual weapon." ”

Hearing this, Prince Dan's doubts were even greater: "Why have I never heard of such a ritual?" ”

"Just listen to it."

Li Yunze waved his hand casually, "Prince Yan, just watch the excitement." ”

Ying Zheng also walked over, walked around the artillery, and said suspiciously, "Taifu, isn't it Juding?" What is the use of such a big iron pillar? ”

"Huh."

smiled casually, Li Yunze still said the same sentence, "Take a look, look at it first, and you'll know later." ”

The preparatory work was quickly completed, and the children of the Mo family stuffed the rationed medicine bag into the bottom, and after pressing it tightly, they held an iron ball weighing more than a pound and stuffed it into the barrel.

Then it was a section of the city wall hundreds of paces away, manipulating the primitive measuring instruments and carefully adjusting the muzzle pointing.

It's really a section of the city wall, built according to the standards of the city wall.

At this time, Ying Zheng finally noticed that something was wrong, and he stepped forward and asked, "Taifu."

"It's fine."

Li Yunze smiled and waved his hand, "It's okay to watch it, anyway, I will use it in the future." As long as the secret of the gunpowder formula is not leaked, there is no way to imitate it. ”

It's not that there is no way, smelling the taste and generally knowing the raw materials, and experimenting again and again, it may not be impossible to experiment.

It's just that by that time, almost all the Kwantung countries have been wiped out by the Qin State.

After sweeping Liuhe, the red-coated cannon temporarily lost its effect.

If you want to use it, you have to wait until the Great Qin Expedition to the west to sweep away the Hellenistic cities left by Alexander in Central Asia.

I can't even say that one day I will be transported to the city of Rome.

Thinking about it for the long term, it's better to arrange the test launch in front of you first.

Under the suspicious gaze of Prince Dan, everyone was taken away and went to the back of the protective wall to stay.

Li Yunze, who was holding a fire sickle, first inserted a guide cable with a thorn at the bottom into the valve, punctured the silk wrapped medicine bag and went deep into it, and then hit the flint to ignite the guide cable.

The guide rope is really not a black technology, there is no cotton to rub out a thin rope with linen, soak it in fire oil and then dry it.

Li Yunze retreated step by step, until the protective wall was here.

This is to avoid the possible risk of exploding, after all, the technology of later generations is so advanced, there is news that the white elephant artillery has killed itself.

Prince Dan's eyes were full of doubts and puzzlement, he really didn't understand what the hell these Ziqin people were doing in front of him.

He didn't believe it or anything, but he really didn't know what it was.

Until a thunderbolt suddenly exploded in my ears!

Prince Dan dared to swear that the loudest sound he had ever heard in his life was the rumbling thunder in the sky when the heavy rain was pouring in the middle of summer.

But now, in the middle of this ravine, he heard with his own ears a thunderclap that was almost close at hand!

At this moment, Prince Dan lay directly on the ground, his legs trembling and almost uncontrollable urine!

Is this Thor descending to earth?

Not only Prince Dan, but also the others around him were not much better.

Even Yingzheng, who had seen the power of black powder to open mountains and gravel before, was also frightened.

He asked Li Yunze with a little horror, "Taifu, this is"

"Huh."

Li Yunze, who looked relaxed, raised his chin slightly, "Qin Wang Cannon, Dagui, ritual also." ”
