Li Yunze was originally unwilling to use firearms.

It is simply that in the age of classical cold weapons, muskets and cannons appeared, which was too disharmonious.

But after learning mathematics, physics and chemistry (basics and chemistry), Ying Zheng gradually approached the direction of science and engineering men.

Especially, I have the greatest interest in gunpowder. If it weren't for the confidentiality, I would have taken it to the Kanto countries to use it long ago.

As the saying goes, "The King of Chu is so thin that he starved to death in the palace."

If the superiors like something, the subordinates will have a lot of things. Since the king likes this, naturally some people are willing to study it to win the king's favor.

What surprised Li Yunze was that the disciples of the Mo family actually did this.

After thinking for a while, Li Yunze bluntly asked, "What does the king want?"

"Well..."

Ying Zheng was asked, and he had never been exposed to relevant knowledge, so he naturally could not imagine the appearance of a cannon out of thin air.

He wandered around in distress for a few times before finally saying, "According to Wuhe's meaning, it is best to make two tripods one big and one small. The big big tripod is the platform, the small big tripod is the set, and a iron ball is made into it..."

Li Yunze understood after listening to a few words. Isn’t this a casing?

And the giant tripod and other...

"never mind."

Li Yunze waved his hand and said, "I'll do it."

Ying Zheng was overjoyed and bowed, "Then please give me the tutor."

"By the way." Before leaving, Ying Zheng said, "The Queen Mother misses the Grand Tutor very much. If she is free, please ask the Grand Tutor to go to the Queen Mother's place to preach."

‘Slurry... yummy...’

What else could Li Yunze say? He could only smile and nod.

Li Yunze also made the big toy that Ying Zheng called for with great care.

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

He also knew very well that with Ying Zheng's personality, if he really wanted to make artillery, he would definitely use it on the Kanto countries first.

So I cast a red cannon first.

The so-called red-clothed cannon is actually called the Red Barbarian cannon.

The so-called red barbarians refer to the Dutch, the red-haired Dutch.

Later, I talked about the red clothes because the Ming court attached great importance to this killing weapon and tied red ribbons to each cannon.

Its prototype is a smoothbore cannon of twelve or even eighteen pounds.

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

Just as Li Yunze was busy making red cannons, the nomadic tribe on the northern grassland encountered an unprecedented terrible blow.

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

The Yuezhi herders, who didn't even have a saddle, were faced with dimensionality reduction strikes with wooden sticks and other weapons, lamenting that they had encountered monsters.

However, soon, people who were sympathetic and pitiful appeared.

The Donghu tribes located in the east also encountered heavy blows from Zhao State during the same period.

Li Mu went out of the frontier to defeat the Donghu tribes and forced Lin Hu and other tribes to surrender to Zhao State.

Kill and captured nearly 100,000 people.

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

The Huns, who were just a vassal tribe under Donghu, witnessed the decline of Donghu with their own eyes and began to annex small tribes and gradually grew stronger.

Li Yunze turned a blind eye to the things outside the window and was devoted to doing his own things.

After the red cannon was finished and the test shot was successful, people were arranged to go to Xianyang City to deliver letters to Ying Zheng.

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

The test launch place is the mountain ridge valley area before. Speaking of the place in northern Shaanxi, there are too many mountain ridge valleys like this.

The valleys are usually very deep and long. Many times, there may be only a hundred meters away between the two hills. However, because of the existence of the valley, it is impossible to get to the opposite side for most of the day.

"Tao Fu."

Ying Zheng brought a young man to Li Yunze and introduced, "This is Yan Dan, the prince of Yan State. He was sent to Daqin a few days ago."

When you go to the Daqin mission, these are all good words that give people face. Just listen to it and don’t need to worry about it.

Prince Dan actually came here to be a hostage.

After all, Yan State is now being beaten by Zhao State and urgently needs Qin State's life to help, so he has to send heavyweight hostages for help.

Li Yunze looked at the young prince Dan, and was undoubtedly a nobleman who was very consistent with the characteristics of this era.

His eyes were a little heavy, and the smile on his face seemed a little weak.

Regarding the direct planner of "Jing Ke assassination of Qin", Li Yunze just nodded and said hello and didn't care too much.

There are so many historical celebrities he has seen, and it has long passed the stage of being excited to see people who leave their names in history books.

On the contrary, Prince Dan is obviously interested in Li Yunze, the mysterious Taifu.

Not only did he wander around Li Yunze, he also kept asking Ying Zheng for information about him.

Unlike the King of Qin who was suppressed by Lu Buwei at this time in history, whose mother Zhao Ji found a wild man again, and under great humiliation and suppression, Ying Zheng had already taken over the power, and his mother Zhao Ji was also calm and did not drag him down. The Qin Dynasty's national strength was booming and it also opened up a huge territory through the strategy of advancing westward.

At this time, Ying Zheng had a much sunny mentality and personality. He was very happy with Prince Dan, who was similar in age, and especially the same sympathy who had been a proton, which made him very good at Prince Dan, and even treated him as a friend.

Even if it was the killing weapon tested by the Taifu, he was willing to bring it with him.

Ying Zheng didn't think there was anything to hide when Prince Dan's inquiry. He said everything he could say, and he also said a lot of things he couldn't say.

As for white paper, printing, curved plows, carts, etc., Prince Dan also witnessed it with his own eyes after coming to Xianyang City.

Of course, Ying Zheng naturally wouldn't say it out, such as the three-piece cavalry set and black gunpowder.

As for this time, it was because Ying Zheng himself didn't know what Li Yunze had made. He thought it was a giant cauldron and had no sense of confidentiality in related aspects at all.

This chapter is not finished yet, please click on the next page to continue reading the exciting content behind! Even the ones that were just said have already shocked Prince Dan.

After learning that these things were actually all from Li Yunze's hands, Prince Dan's eyes looked at Li Yunze, and his eyes were unstable!

Due to the improvement of the quality of steel, the red cannon cast by Li Yunze is not as heavy as the original one, but it also weighs more than a thousand kilograms.

He also equipped the red cannon with wheels, wheels with steering shafts, as well as valves, ground hoes, sight lines and other improvements.

"What is this?"

Li Yunze, who was busy setting up artillery, heard the inquiry sound coming from behind, turned around and looked over to Prince Dan, who looked curious, and said, "This is the Dagui, also known as the King of Qin Cannon, which is a ritual vessel."

Upon hearing this, Prince Dan’s doubts became even more intense, “Why have I never heard of such a ritual instrument?”

"Just listen to a sound."

Li Yunze waved his hand casually, "Prince Yan just thinks it's just for the fun."

Ying Zheng also came over, wandered around the cannon, and wondered, "Tao Fu, isn't it a giant tripod? What's the use of such a big iron pillar?"

"hehe."

He smiled casually, and Li Yunze still said the same thing, "Look, look first, you'll know later."

The preliminary preparations were completed quickly. The Mo family's children stuffed a regular dose of medicine into the bottom, pressed it tightly, and stuffed it into the cannon barrel with an iron ball weighing more than one pound.

Then he manipulated the original measuring instruments and carefully adjusted the direction of the muzzle, a section of the city wall hundreds of steps away.

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

At this moment, Ying Zheng finally realized something was wrong. He stepped forward and asked "Tao Fu..."

"fine."

Li Yunze smiled and waved his hand, "It doesn't matter if you look at it, it will be used in the future anyway. 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. I know the raw materials when I smell the smell. I try again and again, but it may not be impossible to do it.

However, by that time, almost all the Kanto countries had been destroyed by Qin.

After sweeping across Liuhe, the red-clothed cannon temporarily lost its function.

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

Even, I may even be transported to the city of Rome one day...

I've thought about it far, so I'd better arrange the test shot in front of me first.

Under Prince Dan's confusion gaze, everyone was taken away and stayed behind the protective wall.

Li Yunze, holding a fire sickle, first inserted a guide cable with a thorn at the bottom into the valve, pierced the silk-wrapped medicine bag deep into it, and then fired the flint to cause fire and ignited the guide cable.

The guide rope is really not a black technology. You don’t have cotton, rub a thin rope with linen, soak the tinder oil and then dry it.

Li Yunze retreated step by step until the protective wall.
