The use effect of the fireworks that are used for civilian hunting rifles and bullets is not very satisfactory, but it is better because it has sufficient reserves and is finally better than the use of the old black fires.

When it comes to shells, it is even worse. It is too difficult to manufacture conical warheads, so you can only use cast iron solid bullets, iron-shell chain bullets and iron-shell grape bullets that are also speechless. It is important to know that no matter how old flowering bullets are, they cannot save time-detonation. Wu Han is very self-aware. His three-legged cat craftsmanship cannot overcome such cutting-edge technology. It is better to hide his weakness than to show off his ugly head. He was bereavement on the streets when he was young and dropped out of school and went to sea. Wu Han learned his ability to make a living from society. The most regrettable thing is that he did not get the opportunity to go to the legendary Qinghai Hualong Black Workshop and study the manufacturing technology of civil machinery products. There are too many ingredients in the development of local artillery artillery. As a result, he created such a heavy local artillery with advanced level in the 19th century.

To be honest, if an outsider fan wants to create a heavy weapon with a certain technical content, it is no less difficult than teaching an old sow to climb a tree.

Although the earth cannon looks a little ugly and has a lower technical content, the cannon is a cannon after all, and its power is never vague. The cannon and the guns targeting killing are by no means the same level. The cannon is at least a member of the siege weapon family. Whose body is stronger than the city wall? The earth cannon with a low appearance does not look as weak as it looks. According to the information, the cannon fired by twelve centimeters of caliber and fireworks is enough to penetrate three-metre geocompositions with a thickness of more than three meters. It can be imagined that flesh and blood are all unlucky to suffer such powerful blow power. Unless the invader is the legendary mutant lizard Godzilla, or a mythical monster like King Kong, as long as you get a shot, no matter whether it is invulnerable to swords and guns or thick skin, you will definitely have to finish it.

Now that the weapon is in hand, if there is a bobcat beast next time, the smaller one might as well call him on a shotgun, and the larger ones will use solid bullets directly. If one comes, one dies, two dies. The survivors of the Peach Blossom Land do not have to be frowning all day long, because they are unable to resist these evil guests with hair and horns.

Wu Han invited everyone to visit the completed fortress, but unexpectedly he received a lot of sarcasm. After some thought, he decided to let everyone see the true power of this cannon well. Facts are better than words!

The poorly-looking cannon has actually been loaded, and Wu Han came to the tail of the cannon to check the locking device and firing device. Looking at Wu Han's serious and serious look, the audience laughing and laughing became serious. Xu Yunyun, who was closest to Wu Han curiously, leaned over to observe his movements, and said curiously:

"Hey, are you going to try it out?"

After hearing Xu Yunyun's question, Wu Han turned to look at her, but smiled without saying anything, but his hand did not stop. The target of the fire was ready for fire. Last time, the cat was bitten by Wu Han's poor mouse and detonated the ammunition in his backpack, and finally exploded half of the bear-shaped monster with its head. Afterwards, most of the intact fur was peeled off by women as if they were venting anger. Now the bloody corpse was lying horizontally near the entrance of the observation deck. The corpse that was frozen into bloody was just used as the target for the test shot.

Turning the shaking handle with difficulty, Wu Han lowered his muzzle and measured the ballistics through the sight, and was sure to aim at the corpse of the giant beast. Before launching, he stood up and said solemnly:

"Well, everyone should pay attention. Clog your ears and open your mouth. Yes, a little bigger."

Anything will undergo a transformation from quantitative change to qualitative change when it reaches its extreme. If the noise is large enough, it will be noisy. Moreover, in a nearly completely closed environment like a cave, the huge roar generated by the artillery fire continues to echo, and the noise problem will become fatal, and it is not a sensational statement that leads to death in serious cases. Wu Han naturally does not want to see such a tragedy. After confirming that everyone will do it, he also stuffed cotton balls into his ears, and then opened his mouth ridiculously. Then Wu Han carefully reached out and pulled the rope that was hanging down at the tail of the cannon.

"Boom...boom..."

As the fuse was pulled, an orange-red hot storm broke out in front of the black earth cannon muzzle. Then, the shining fire illuminated the surroundings, making people dare not look at them. At the same time, the strong recoil generated by the cannon fire made the rocky ground tremble. Then, a shell slightly larger than a coconut flew out in thunder and was in the middle of the wreckage of the giant beast dozens of meters away. With a strange sound like shattering ice and tearing apart the cloth, this solid iron bullet was like a chopstick piercing the newspaper, easily penetrated the extremely hard-frozen corpse of the giant beast.

After penetrating the corpse, the shells continued to fly to the ice and snow outside the cave, and disappeared in the blink of an eye. God knew where the last shot went.

The rumbling sound lingers, and it has nothing to do with the beauty of the three-day circling beam. It is barely said, it is very similar to the crazy disco that drives the subwoofer to the limit. When the survivors slowly recover from the shocking state of the cannon, everyone suddenly realizes that the remains of the giant beast have been torn apart by the seemingly untechnical shell. This corpse, which has been baptized by many days of cold wind, was so frozen that even the sharp blade could not be damaged, turned into countless debris and flew around the tunnel, constantly hitting the wall of the cave. The tiny bones and ice chips made a crackling sound when they fell, and it lasted for a long time before gradually calming down.

With a pair of beautiful eyes as narrowed as apricot kernels, Zhou Chen looked at Wu Han's revealing face and said:

"This thing seems to be a little more effective than it seems."
