Liu's "Meteor Bullet" is almost a large single-tube firework. The rear end is equipped with launching medicine, but the warhead part is different. The fireworks need to be colorful. Of course, the "Meteor Bullet" is not for viewing. It is used to kill enemy soldiers, so the warhead part is filled with gunpowder and iron nails, lead balls and porcelain pieces.

Because the power of the explosion is very limited, the guerrillas used the mines and grenades of the country during the War of Resistance Against Japan. Unfortunately, these mines could hurt people within two or three meters, and only the unlucky Japanese traitors would die on these gates. Ma Fen is certainly aware of the limitations of the gates. Well, there is no way, that is, increase the charge amount. The mines are fine, and it is nothing to be stupid, but the grenades cannot be made into "stupid bullets" that are stupid, black and thick. Is it just going to smash a few meters away? Well, unless it is used to defend the city.

There are two main types of killing and damage caused by explosions, one is broken killing and the other is shock wave killing. Of course, don’t consider shock wave killing. Shock wave killing is the killing effect that only explosives can produce. As for **, it is good to be able to form broken killing.

During the Northern Song Dynasty, there were early bombs based on the explosion and fragmentation of the ** explosion, which were called "Pi Li Cannon", which contained gravel and porcelain pieces. After the explosion, fragments flew away and injured people with kinetic energy.

Unfortunately, the power of the explosion is limited, which makes the debris not very kinetic energy, resulting in limited killing.

However, as a high-IQ person who knows science, Liu Wenbing thought of a solution. What method did he think of? That is the "rocket" that boosts two-stages! Isn't it just that the speed is not high enough? There are already successful cases in later generations! If a satellite wants to achieve the first cosmic speed and the second cosmic speed, the tricks are divided into rockets and multi-stage rockets. If one level is not enough, then two levels. If two levels are not enough, then three levels, and in the end, the speed will always be increased.

Liu Wenbing then created a strange second-stage propulsion "rocket". After igniting, the first-stage "rocket" rocket was started, completing an acceleration process, then ignite the second stage, and accelerate again. When the second stage is accelerated, it explodes again. Due to a considerable initial speed. After the explosion, it will accelerate again, and the speed of the debris that explode forward greatly increases. At this time, the kinetic energy is very impressive. Even if it cannot compete with the high-explosive bomb, compared with the static explosion of ** bombs, there is no problem at all.

After Ma Fen tried the weird "rocket" created by Liu Wenbing, although he found it funny, it was undeniable that it was really effective. The problem is that the thing is very unreliable, and the second level often cannot be fired.

The reliability of the third-stage ignition is really poor. Under Ma Fen's prompt, the improved version designed by Liu Wenbing removed the second level and simplified it to the launch level and blasting level. The blasting level borrowed the design of directional infantry thunder. Liu Wenbing designed a solid baffle in the partitions of the launch level and blasting level, so that killing fragments such as iron nails can only explode forward during explosion. With this simplification, the length was greatly shortened, but the power of the explosion was not less than that of the previous second-level "rockets". Well, it is completely comparable.

After some trial explosion, Ma Fen felt that the effect was OK. Of course, the thing Liu Wenbing created was still very limited to the lethality of the armor. The second disadvantage is that the range is limited. The key is that if you shoot far, you can only be considered a static bomb, which is greatly reduced in power. The third disadvantage is that the launch trajectory has no accuracy, and you can only rely on the hope of killing.

Overall, it is better than a simple ** bomb, and the effectiveness of gunpowder is at least two or three times higher.

However, in this way, it would be a bit unreliable to call it "rocket", but this is not difficult for Liu Wenbing. Liu Wenbing named the thing he invented "Meteor Bomb". Liu Wenbing felt it was very vivid. Connecting the launcher and a set of things, it simply called "Meteor Chasing the Moon".

The transmitter is made of bamboo tubes. The bamboo tube is brushed with tung oil, then twisted a circle of twine outside the tube, and then brushed with a layer of tung oil. It looks very strong, but in fact it is also very strong. After testing it many times, it feels okay.

However, the density of the launch today was too high, and the four launchers were almost constantly firing for a moment. As a result, two launchers immediately burned, and the launchers in Tang Kai and Fang Yishan's hands also began to emit smoke, because there were several "meteor bombs" in front of them that could not light the fire. There was a cooling interval, which allowed these two launchers to continue to fire.

Even though the "Meteor Bull" on the mountain was half thin, the barbarians at the foot of the mountain continued to remain stunned. The "Meteor Bull" may not be any threat to the protective armored soldiers, but it is really effective in dealing with these top-body barbarian soldiers. Iron and lead balls were swept over one by one, and the middle one was covered in blood. Even if the barbarian soldiers who were very nervous and fearless, they also felt afraid.

Liu Wenbing was very proud and thought that he would change the launcher to iron next time, so that would be foolproof.

At this moment, a few "swooshing" sounds, several arrows broke through the air, and an arrow was nailed to the elephant's leg. The elephant was in pain and walked forward a few steps. Liu Wenbing suddenly felt that he had lost his protection.

Liu Wenbing subconsciously moved with the elephant. At this time, the guide suddenly pointed to the rear and exclaimed:

"Barbarian soldiers, behind, behind, the barbarian soldiers came from behind."

Liu Wenbing looked up and saw, Oh my god, several barbarian soldiers emerged from the grass, and they were also topless. However, the spears in the hands of these barbarian soldiers were all equipped with iron spearheads, as if they were elite soldiers! Damn! They actually came to do sneak attacks.

At this time, the two elephant drivers didn't know where to go, and more barbarian soldiers appeared in the grass.

But at this time another launcher was burned, and only one was still barely firing a "meteor bomb", but the firepower weakened, and the other was increasing. The barbarians at the foot of the mountain immediately rushed upwards screaming.

Liu Wenbing thought to himself, it's over.

A barbarian rushed up, but he didn't notice that a barbed wire was blocked behind him. He rushed too fast. He immediately hung it on the barbarian wire, pulled off a piece of flesh, and blood was poured out. However, the barbarian soldier was quick and as if he was like a monkey. As soon as he pressed the trunk of the tree, he turned over and rushed to Liu Wenbing.

Liu Wenbing was shocked and scared, and shouted hysterically:

"Damn dead monkey, kill you, kill you!"

He raised his knife and pounced on it.

At this time, there was no way to retreat, and Liu Wenbing had to fight to the death.

The barbarian soldier slashed his spear. Liu Wenbing wanted to avoid it, but unfortunately he was one step slower and stabbed his spear directly into his right chest.

"It's over, are you just dead like that!"

Liu Wenbing closed his eyes in despair, feeling the violent impact almost knocking him out, but his right hand subconsciously swung the knife and felt something slashed.

Not dead yet!

When I opened my eyes, I found a barbarian soldier falling down in front of me, twitching on the ground, and the knife in my hand was dripping with blood.

I killed someone!

While Liu Wenbing was stunned, two barbarian soldiers surrounded him and slashed his spear.

Fortunately, Bai Er fired a crossbow arrow in time. Pup puff puff puff puff puff puff, and saw two crossbow arrows nailed to each of the two barbarian soldiers' faces and chests, and they turned over and fell down.

Ma Fen shouted:

"Liu Wenbing, kill me! I'm afraid of a ball."

Liu Wenbing suddenly realized that he was wearing iron breastplate and that ordinary iron spear could not hurt him. When he thought of this section, his courage suddenly became much stronger. At this time, he ignored the injury to his left arm and just slashed at the barbarian soldiers who came out.

The crossbow in Bai Er's hand was one of two cylindrical crossbows. The cylinder was filled with thirty crossbows. Facing a group of barbarian soldiers surrounding them from behind, Bai Er's hand was linked, and more than twenty crossbow arrows were shot out continuously, and seven or eight barbarian soldiers who were sneaking into the ground.

Liu Wenbing raised his knife and waved it, slashed on a spear that was pricking, rushed forward, and pushed the knife forward with one knife into the lower abdomen of a barbarian. He immediately splattered blood, splashing his hands full of blood.

"Call, shoot these damn monkeys to death!"

Bai Er quickly changed into a cylinder filled with crossbow arrows and pressed it onto the mechanism. Pupu Pupu Pupu again fired again. Thirty crossbow arrows shot out, and another group of barbarian soldiers fell into a pool of blood.

It turns out that this crossbow is really amazing! It’s just like the submachine guns in later generations. Liu Wenbing thought to himself, this is more fucking good than our “meteor bullet”!

Bai Er grinned:

"I said, this magic crossbow is more useful and enjoyable!"

Bai Er was proud to himself. In the blink of an eye, he changed another quiver, and then pressed it on and shot it again.

When he ejaculated at the fourth stitch, he suddenly got stuck, and Ren Baier didn't respond at all no matter how he broke it.

A barbarian soldier took the opportunity to rush to Bai Er and stabbed him with his spear. Bai Er flashed anxiously and was stabbed in his thigh. Bai Er was furious, pulled out a dagger, and stabbed it into the chest of the opposite barbarian soldier with a knife.

At this time, Liu Wenbing lost Bai Er's firepower support and immediately fell into the siege of the barbarians. However, Liu Wenbing didn't know where the courage came from. While resisting, he also reminded:

"Bai Er, change to another quiver."

Bai Er's quiver was probably crushed or something. The crossbow arrow was stuck and couldn't be shot out. Maybe another one could do it.

Bai Erde reminded him, and he changed into a quiver in a hurry. He could shoot arrows again. This time he saved Liu Wenbing again. Liu Wenbing was stabbed several times by a spear. Fortunately, these barbarian soldiers were a little slandered and took the chest and lower abdomen to greet him. As a result, Liu Wenbing leaned against his chest and resisted. Although his chest was overturned, he still did not fall down.

Now the barbarians and Ma Fen and others in front were also close at hand. At this time, the Zhuge crossbow and the cylinder crossbow began to show their power. At a distance of more than ten meters, the continuous firepower of the crossbow was unstoppable, and they shot and killed more than a dozen barbarian soldiers in one go.

However, the Zhuge crossbow's arrow loading process is too complicated. After firing one in a row, it can only be thrown aside. Only another cylinder crossbow can quickly change the crossbow arrow quiver. In this way, Ma Fen had to bite the bullet and fight with few against the crowd, and began melee combat.

After a hand-to-hand combat, five special training soldiers were killed one after another. Ma Fen and everyone else were injured. When they were about to be buried in this small mountain bag, they finally waited for reinforcements brought by Wang Feng.
