Heavy snow covered the mountains, and the people stopped in a flat place. It's a valley mouth, and it's quite open when you look inside. Moreover, this valley is not small, and the high mountains behind it are at least ten miles away.

The institute removed parts from the crabs and leeks and began assembling the cannons. The old man walked up to Jiang Xingchen and asked in a low voice, "Boy, it's time to tell us, what is this thing?"

"Cannon!" Jiang Xingchen said succinctly.

"Cannon, what is that, is it more powerful than a ballista?" Zhao Danqing also ran over and approached him to ask.

"Isn't this nonsense!" Before Jiang Xingchen could speak, the old man counted Zhao Danqing down: "If you don't have a ballista, why study this thing!"

As he spoke, the old man turned his head and said to Jiang Xingchen: "Boy, I didn't say you! Look at the name you gave it, the cannon! It's just home! It's not majestic at all, since it's more powerful than a ballista, you should ...... it."

The corners of Jiang Xingchen's mouth twitched, and he knew that he couldn't pay attention to this old thing, and when he talked about it, it was endless, like Tang Seng.

"I don't have time to think of a name...... Jiang Xingchen originally wanted to interrupt the old man, and then dodged. But as soon as he spoke, the old man hurriedly said: "I have you if you don't have time, leave the name to me to think!"

"Then you guys think slowly!" Jiang Xingchen was really speechless, no longer paying attention to these two goods, waved his hand, and turned around and walked back.

This time the old man didn't come over to bother him, he stood in place with a frown, and began to meditate. Zhao Danqing also stopped, like the old man, he lowered his head and thought about his name.

Jiang Xingchen walked back about fifty meters and beckoned Mo Hongxian and the second brother to come over. Said: Dig a pit here, it's bigger. Let all of us go down. "Although there is basically no problem with the cannon, it is also important to pay attention to safety. What if it blows up. The terrain here is flat, unlike the slopes behind the territory, where there are rocks everywhere to hide. So it was necessary to dig a trench and hide.

"Okay!" Mo Hongxian responded, beckoned to the members of the Bauhinia group, and dug up with a pickaxe and shovel.

Although everyone's cultivation is not low, the north is freezing and now is the coldest time. The soil is frozen like an iron lump, and it doesn't dig up quickly.

After about half a month, one is five meters long and one meter wide. A large pit one and a half meters deep was dug up. The cannon on the other side was also assembled.

Jiang Xingchen first asked the crab to come over and unloaded the cannonballs in the bag on his body into the pit.

"Brother, this bomb is different from the previous one!" the second brother asked in surprise when he saw the shell. The bomb used to be like a small watermelon, but now it is almost the same as Jiang Xingchen's cannonball.

"This is called a cannonball, it's not a bomb! And the process of making zuò is very different from a bomb!" Jiang Xingchen explained, ran to the cannon, loaded the cannonball, and then ran back with a long rope.

"Hide in the pit! It's about to begin!" Jiang Xingchen greeted loudly.

Catwoman. Mo Hongxian, the second brother, and a group of people jumped into the pit one after another, and no one had any doubts. In the past few days, they have all seen Jiang Xingchen's real yàn. We all know that the danger is too great.

The old man and Zhao Danqing also put aside the name matter for the time being, and ran over, they all wanted to see how powerful this thing was!

Inside the tunnel. Everyone didn't speak, and even the chattering old man shut up. Lie on the edge of the pit and look ahead.

Jiang Xingchen took a deep breath and counted, "One." Two, three!

As the last two words came out, Jiang Xingchen pulled the rope hard, and his head quickly lowered. The old man, Zhao Danqing, and the others did the same, bending down quickly and hiding in the tunnel.

"Bang!" There was a loud bang, and after a second, everyone looked up immediately when they felt fine, and saw that there was silence in front of them.

"Boy, what's the matter, there's no movement?" asked the old man in amazement.

Zhao Danqing, Mo Hongxian, the second brother, and the little cat woman all turned their heads to look at Jiang Xingchen.

But at this moment, a roar suddenly came from the distance, followed by echoes, as if rolling thunder sounded in the sky.

"Ringing?" the old man blinked and asked in surprise, "Where did this Nima go?"

"Look, old man!" the little catwoman jumped up and pointed to the mountain peaks in the distance.

In fact, there was no need for the little cat woman to prompt everyone, everyone had already seen it, and they saw the snow on the distant hillside rolling downward, and then the rumbling roar came into their ears.

Although the mountain is at least ten miles away, such a large movement can be seen clearly with the naked eye.

"Snow... Avalanche!" Zhao Danqing swallowed his saliva and muttered, "Did this cannon hit so far?"

The old man is stupid, the previous ballista could hit thousands of meters, that is, two miles, which is already amazing. The year before last, there was a big war, and the eight kingdoms couldn't find the north! But now, a cannon is actually ten miles away, if this kind of weapon is put on the battlefield, then how can it be played, if you don't see anyone, you will be bombarded, it is simply cheating.

"Boy, the avalanche over there, can't you really hit it with cannon?" the old man asked, with a range of more than ten miles, he really couldn't believe it. How is it possible to hit so far.

Mo Hongxian also swallowed saliva and said: "It shouldn't be! If you really fight so far, it will be too easy to kill anyone in the future, and you can solve it with one shot more than ten miles away!"

The second brother listened to it from the sidelines, and couldn't help but shudder, this was really scary.

Jiang Xingchen ignored them, but lowered his head and whispered to himself: "From the launch of the cannonball to the change of the snowy mountain, it takes about four seconds! That is to say, the speed of the cannonball reaches more than a kilometer per second... In this way, the explosive power of the Yuan Stone should be stronger than that of gunpowder, this is the first time it has been developed, and there should be room for significant improvement in the future, so that the number of Yuan Shi can be reduced, and the current propulsion force can still be maintained......"

When Jiang Xingchen whispered, several researchers were not idle, and those who had pen and paper in their hands wrote down Jiang Xingchen's words and used them as the direction of their future research.

"Boy, what do you say? Are you talking about the avalanche on the hillside over there, you really hit it with cannon?" The old man saw that Jiang Xingchen didn't move, so he slapped him angrily.

Jiang Xingchen came back to his senses at this time, looked at the people with doubts on their faces and said with a smile: "What do you say, if it weren't for this cannon, you would think that the avalanche would happen casually!"

"I'll it! The power of this cannon is too great!" Zhao Danqing couldn't help shouting.

The old man frowned and asked, "Boy, once this weapon is available, the emperor will ...... there."

"Hehe!" Jiang Xingchen smiled and said, "My territory is independent, and the intellectual property rights are clearly written! If the emperor wants it, I will sell it to him! We are still very happy to cooperate now!"

The old man groaned for a moment and said in a low voice: "You just have to know it yourself!"

"Don't worry! I have the bottom in my heart!" Jiang Xingchen smiled and turned out of the tunnel. Then along the flat ground back, the tests of the cannon continued......

From morning to evening, all the 100 shells brought were empty, and the cannons withstood the test without exploding. This also marks the official successful development of the cannon!

After a day's practice, Jiang Xingchen also roughly figured out the range of the cannon, which was about seven kilometers.

At the end of the day, the most tired ones are the Bauhinia mercenary group and the little cat woman. The former not only needs to open roads, but also need to dig tunnels. Catwoman keeps running back and forth, looking for where the cannonballs will land.

After returning that night, Jiang Xingchen cooked by himself and took out the liquor brewed for the third time to treat everyone.

The third brew of sorghum wine is passed on by tourists, but no one has ever drunk it, and after it is brewed, it is put in the cellar to precipitate, and this is the first time it has been taken out.

The little cat woman drank the wine, her eyes narrowed with joy, and she felt that no matter how tired she was during the day, it was worth it.

The old man drank only one drink, and then took away the two altars on the table and hid one altar. As a result, there was a lot of fighting.

At the end of the dinner, Jiang Xingchen drew a map and sent it to the Cursed Land, asking him to install a gun emplacement for the five newly built seven-story treasure ships.

Then he went to the research institute and called the researchers and craftsmen who had studied the cannon with him, and asked them to bind the various parts of the cannon and the size specifications of the shells into a book.

Now that time is pressing, he doesn't know if a bomb has been developed overseas. Even if the opponent didn't steal the manganese steel, the use of a normal-range launcher would still be a threat to the royal fleet.

Therefore, Jiang Xingchen was going to take these people to the Cursed Land and give birth directly there, so that he could save a lot of time.

As for the materials needed, I can only make the ribs hard, and I have to make a few more trips to be responsible for transportation!

That night, Jiang Xingchen, who returned to the lord's mansion, told Mei'er that he was leaving for a while. Due to the urgency of the matter, of course Mei'er will not stop him, but just tell him to pay attention to safety.

Early the next morning, Jiang Xingchen was about to go to the research institute. The old man and Zhao Danqing ran over.

"Boy, I came up with the name of that weapon yesterday, it's called Heavenly Thunder, how about it, majestic!" The old man pinched his waist and laughed, with a sway on his face.

"......" Jiang Xingchen was speechless, and after holding it all night, he held back such a ghost name!

Zhao Danqing grabbed it in one step and said loudly: "Brother, don't listen to this old thing, what the hell is the thunder booming in the sky! Listen to me, the avalanche cannon is much more powerful than his!"

"Poof!" Jiang Xingchen almost didn't spray, you are even more unreliable, avalanche cannon, why don't you call it a urine collapse cannon.

"Zhao boy, you can't find it, are you! Why is my name not good! Tianlei is much stronger than your avalanche, okay!" the old man grabbed Zhao Danqing's neck and said viciously.

Zhao Danqing did not show weakness, and said loudly: "It's not good-sounding, it's still cheesy! It's recognized that you can't give a name, and you named my slow loris Xiao Chenchen at the beginning!"

"Oops!" The old man's eyebrows were raised, what do you mean by mentioning this, isn't this letting the little soul take revenge on me.

"Okay!" Jiang Xingchen stopped the two of them and said loudly: "You guys are fighting for each other, do you have a result?" As he spoke, he threw a citrine coin to the two of them, turned his head and walked out. (To be continued......)
