Zhou Daixu observed the situation, saw that the canyon was already crowded with soldiers, and said solemnly, "King Rui!" Let's shoot! ”

Situ Ran was wearing silver armor, and the flag behind him "popped" with the wind on the side!

The unprecedented sense of solemnity made Situ Ran's heart a little tense, and he solemnly raised his right hand, and shouted loudly with internal force, "Open the cannon!" ”

The gunner held the torch and lit the fuse with his low hand, and the sound of "poof" touched the nerves of everyone present, while the two gunners remained still, as if they were accustomed to such a scene.

Since receiving the drawings given by Xiao Tao, they have stopped all other weapon research except for making explosives, and have continued to experiment repeatedly.

Xiao Tao's drawings are not detailed, but a few people who are used to making weapons have a strong interest in the drawings as soon as they see them.

After two days of sleepless discussions, they were able to deduce the basic principle of the cannon, that is, the combustion of the propellant produces a large amount of gas, which pushes the projectile forward along the barrel with great acceleration. The projectile gains maximum velocity at the moment it leaves the muzzle, and then flies along a certain trajectory towards the target.

The first cannon made, after being fired, was very powerful, but the gas pushed the projectile forward and pushed the cannon back to recoil, so that the gun carriage could not be fixed, and it flew far back, unable to continue the next shot!

Later, they repeated experiments, and finally used the muzzle brake to reduce the recoil energy of the gun, and increased the weight of the base to keep the gun carriage fixed!

And the two gunners have lit gunpowder countless times in the past few days for experiments, and they have become accustomed to it!

After the two loud bangs, as the two black shadows with fire cut through the sky and fell into the middle of the opposing soldiers, the "boom boom" exploded, the people turned over on their backs, and the ground rolled!

Situ Ran covered his ears and opened his eyes wide, and couldn't close his mouth when he opened his mouth for a long time, "My God! It's five thunderstorms in the sky! ”

Wang Renjie and Zhou Daixu didn't expect this cannon to be so powerful!

Obviously, Yin and them didn't expect that the two unexpected bombings almost bombed the momentum he had accumulated!

Yin He didn't see anything in the rear that emitted such power, but this battle was enough to make him chaotic, he didn't know that they actually had such a powerful firearm! Is it true that God doesn't help him?

And over there, Situ Ran danced excitedly like a child, this cannon said that one enemy and one hundred are light! Holding Wang Renjie's arm, he laughed excitedly, "Uncle, uncle, we have won!" It's a win! ”

Wang Renjie smiled helplessly and shook his head, this child appeared in his original form as soon as he was excited!

Zhou Daixu couldn't stop laughing when he saw him like this, he was really young and couldn't hold his breath!

Because the cannon was urgently researched, there were only ten shells.

As soon as a few people discussed, they took advantage of the surprise of hitting the other party, and then sent two consecutive shots to completely suppress the arrogance of the other party. If you can't beat it in the end, use the last cannonball to cheer you on! Moreover, the amount of explosives that Situ Yu provided to them was still very sufficient, and they were enough to match the opponent's men and horses!

Immediately after another burst of bombardment, Yin He's army was a little chaotic, the horses neighed, and the moans in the crowd came and went, and Situ Ran They hadn't sent a single soldier yet, they had already suffered a lot of casualties!
