?“ Master, it's earth-shattering when the cannon is tested later, so it's better not to stay here. ,//" Wu Dong turned to Master Li and said.

"Why is that?" Master Li was stunned.

"I'm afraid it will affect our children." Wu Dong said with a smile.

When the cannon was fired, the sound was too loud, and if a pregnant fu like Master Li stayed here, her body would definitely be affected, and it would definitely not be good for the child, so Wu Dong must let her go.

Hearing Wu Dong say this, Master Li was taken aback. She waited so long for her to finally have a child, and for her, the child was more important than her own life. At that moment, she hurriedly left here in a car and headed in the direction of Incheon City.

After Li Shishi walked away, Wu Dong ordered to start testing the artillery.

Dozens of people carried the huge bronze cannon to the open space south of the quartermaster camp, and then stood here, waiting for Wu Dong's final order.

"Let's get started!" Wu Dong said lightly.

Although the expression on his face was normal, his heart was unusually expectant! Artillery is the dividing line between cold weapons and hot weapons, and the emergence of hot weapons will completely change the situation of war. If Liangshan can have the world's earliest artillery in this era, the combat effectiveness will also be greatly improved, and it will also be of great benefit to shorten the gap with the nomads.

Ling Zhen and several craftsmen were there to check the artillery's energy and then put the fire yào into it, and finally put a cannonball in. This cannonball was a mén iron bullet, which was different from the earliest stone bullets used in history, and it was also different from the lead bullets used later.

Ling Zhen held a torch in his hand and lit the fuse tremblingly.

A moment later, a flash of fire suddenly appeared from the artillery, followed by an earth-shattering loud bang, and for a moment, the heavens and the earth were shaken, and several soldiers fell to the ground at once. As for Ling Zhen and the others, they naturally fell to the ground.

And Wu Dong, whose martial arts are extremely strong, is still standing there at the moment. He looked into the distance, only to see a cloud of smoke rising in the distance, it seems, this artillery was successfully tested?

"Grand Duke, we seem to have succeeded?" Ling Zhen got up from the ground, ran to Wu Dong, and shouted excitedly.

It's a pity that Wu Dong's ears can barely hear at this time, and he only sees Ling Zhen's mouth open non-stop, and it took a long time for him to recover, and the people around him recovered from the shock brought by the cannon.

"Good boy, is this artillery? It's like thunder is ringing! The soldiers around him were talking.

"If this thing is put on the battlefield, the sound alone can scare countless horses!" Other soldiers said so.

"Let's go and see how shè Cheng is and how powerful it is." Wu Dong hurriedly said.

He rode his horse forward, and the rest of the soldiers and craftsmen hurried forward after him. Everyone was curious about the outcome, and they wanted to see how powerful the cannon really was.

Soon, Wu Dong came to the crater, and he couldn't help but be overjoyed when he saw that the range of this gun was more than 700 meters! This cannon is unusually primitive, and the shè is much worse than the artillery of later generations, but it is much stronger than the current trebuchet! Nowadays, the distance of trebuchets is generally about 200 meters, and the distance of the trebuchet improved by Yangsan can reach up to 300 meters. In later generations, when the Méng ancients fought in all directions, they studied the return cannon, and the shè distance was only 400 meters. And this primitive artillery, which had just been developed, compared these trebuchets to all of them.

"Governor, that's great!" After Ling Zhen ran to Wu Dong, he measured it carefully, and then shouted at Wu Dong.

"Well, pretty good! It's just that shè cheng is not enough, the barrel is too heavy, and the other is a solid bullet, and the power is very average! Wu Dong said.

"Huh? Governor, isn't this kind of power enough? Ling Zhen couldn't believe it.

"A real cannon can cover tens of miles, and a single cannon can kill hundreds or thousands of people...... However, I am afraid that I will not see such a cannon in my lifetime. In the last sentence, Wu Dong sighed.

"Grand Duke, are there any other bombs besides solid bullets?" Ling Zhen didn't believe what Wu Dong said at all, if there was really such a weapon, it would definitely be used by the gods in the sky, and it would be impossible for mortals to develop it, he was very interested in the "solid bullet" that Wu Dong said, and wanted to know why Wu Dong was dissatisfied with the "solid bullet".

"In addition to solid shells, there are also open huā shells, that is, shells filled with fire yào, and then filled with countless steel balls and the like. Let the shell explode the moment it touches the ground, and use the blasting power of the explosion to bounce something like a steel ball out and inflict heavy damage on the enemy. It can also be filled with fire purely, but the general fire is only afraid that it will not work. Wu Dong said while meeting the relevant memories in his heart.

Many of the shells in later generations were directly filled with fire, and a large piece of fire was exploded, but unfortunately the fire shell technology in this era was very backward, and if it was purely filled with fire, it was not much lethal at all, so it was necessary to make open shells according to what Wu Dong said.

Ling Zhen was very curious about what Wu Dong said, he was a person who was concentrating on technology, and he didn't care much about his status and so on, so he squatted down next to the crater at the moment, scratching around on the ground, studying what Wu Dong said. Occasionally, he would raise his head and study with Wu Dong, but Wu Dong didn't care. In the end, Wu Dong also squatted down and studied with him.

In fact, the principle of artillery is not very complicated, and primitive artillery like this has almost no technical content, mainly the production of cannon barrels, if you can make cannon barrels, you can send out projectiles. Historically, in the Southern Song Dynasty, there were rockets that used giant bamboo as a tube, and the principle of this rocket was the same as that of primitive artillery.

The two of them squatted down to study, and those fire craftsmen also squatted down, listening carefully to the conversation between the two, and they all benefited a lot.

"Governor, how do you know so much?" Seeing that it was almost dark, the two of them stopped, and Ling Zhen asked excitedly and movingly.

"These things...... I was born with that! You should study the artillery well, strive to make the weight of the artillery lighter, make the artillery travel farther, and be sure to study the huā shell! If you can reduce the weight of the artillery to half of what it is now, make the shè distance of the artillery reach two miles, and at the same time develop the huā shell, I will reward each of you with a thousand taels of silver! Wu Dong thought for a moment and said.

"Huh? So much! "The craftsmen around were stunned in disbelief.

1,000 taels of silver, which is an unimaginable amount of money in this era! Now the value of silver is still very high, to the Qing Dynasty, silver greatly depreciated, the Qing people in the Confucian history written, Fan Jin in the Si school as a teacher, only 2 taels of silver a year, this is enough for a family of three, not to mention 1000 taels of silver?

On the border between the Khitan Kingdom and the Great Song Dynasty, a few people are coming to the south at this moment.

"Master Park, we have finally come to Da Song!" There was a man looking at the city in front of him, and his face was full of tears.

"Yes! Finally came to the Great Song Dynasty! However, we did not contact the Jin Kingdom, only the Great Song Dynasty, and I am afraid that we will not be able to drive away those invaders! The man in the lead said gloomily with a stubble on his face.

"Anyway, I've finally come to a safe place!" There is humanity.

"Master Park, where are we going now? Do you go directly to Bianliang, the capital of the Great Song Dynasty? "It's humane again.

"Yes, go to Bianliang, meet the emperor of the Great Song Dynasty, explain to him the situation in Goryeo, and beg for his help!" Park is humane.
