Liu's "meteor bomb" is almost a large single-barrel firework, the rear end is loaded with projectile, but the warhead part is different, the fireworks want to be gorgeous and colorful, "meteor bomb" of course is not taken to see, it is used to kill and injure enemy soldiers, so the warhead part is loaded with gunpowder and iron nails, lead pellets and porcelain pieces.

Because the explosion power of ** is very limited, during the Anti-Japanese War, the guerrillas used ** land mines and soil grenades, unfortunately, these ** can hurt people within two or three meters, only very unlucky devils and traitors will die on these**. Of course, Ma Fen is well aware of this limitation of **. Well, it's not that there is no way, that is, to increase the charge, the mines are okay, the stupid black and thick are nothing, but the grenade can't be made into a stupid and black "stupid bomb", is it just ready to smash a few meters away! Well, unless it's for defending the city.

There are two main types of explosion killing, one is fragmentation killing, and the other is shock wave killing, of course, don't think about shock wave killing, shock wave killing is the killing effect that can only be produced by explosives, as for **, it is good to be able to form fragmentation killing.

During the Northern Song Dynasty, there were early bombs based on the destruction of ** explosive fragments, called "thunderbolts", which were filled with broken stone porcelain pieces and the like.

Unfortunately, the power of the explosion is limited, so that the kinetic energy of the fragments is not high, and the damage is limited.

However, as a highly intelligent person who understands science, Liu Wenbing thought of a way. What can I do? That's a two-stage booster "rocket"! Isn't the degree high enough, there are already successful cases in later generations! If the satellite wants to reach the first cosmic degree and the second cosmic degree, the tricks are divided into bundled rockets and multi-stage rockets, one level is not enough, then two levels, two levels are not enough, then three levels, and finally the degree can always be raised.

Liu Wenbing then came up with a strange two-stage propulsion "rocket", after ignition, the first stage of the "rocket" rocket started, completed a process of addition, and then the second stage was ignited, and then added, and when the second stage was added, it exploded again, because there was a considerable beginning. After the explosion, add it again, and the fragmentation of the forward explosion is greatly increased, and the kinetic energy at this time is very good, even if the enemy is not able to high-explosive bombs, but compared with the static explosion of ** bombs, the lethal kinetic energy is two or three times that is no problem at all.

After Ma Fen tried the strange "rocket" made by Liu Wenbing, although he thought it was funny, it was undeniable that it was really effective. The problem is that it's very unreliable, and the second stage often doesn't ignite.

The reliability of the three-stage ignition is really poor. Under Ma Fen's prompting, the improved version designed by Liu Wenbing removed the second stage and simplified it into the shooting stage and the blasting stage, the blasting class borrowed the design of the directional infantry mine, and Liu Wenbing designed a solid baffle in the compartment of the shooting and blasting stages, so that the killing fragments such as iron nails could only explode forward when exploding. Such a simplification greatly shortened the length, but the explosive power was actually no less than the previous two-stage "rocket", well, it was completely comparable.

After some test explosion, Ma Fen felt that the effect was okay, of course, the lethality of Liu Wenbing's armor was still very limited. The second disadvantage is that the range is limited, and the key is that if it hits far, it can only be regarded as a static bomb, and its power is greatly reduced. The third disadvantage is that the shooting trajectory has no accuracy at all, and we can only hope for face killing.

In general, it is better than a simple ** bomb, and the effectiveness of gunpowder has increased by at least two or three times.

However, in this way, it is a bit unreliable to call it "rocket", but this is difficult for Liu Wenbing, Liu Wenbing named his Ming thing "Meteor Bomb", and Liu Wenbing felt that it was very vivid. Even the upper launcher, a set of household goods, is simply called "meteor chasing the moon".

The shooter is made of bamboo tube, the bamboo tube is brushed with tung oil, and then a circle of twine is twisted outside the tube, and then a layer of tung oil is brushed, which looks very strong, in fact, it is also very strong, and it has been tested many times, and it feels okay.

However, the density of today's shooting is too high, and the four shooters are shooting almost all the time, so that two shooters are immediately scorched, and the shooters in Tang Kai's hands and Fang Yishan's hands also began to smoke, just because there are a few "meteor bombs" in front of them that can't ignite at all, and there is a cooling interval, so that these two shooters can continue to shoot.

Even if the "meteor bullets" on the mountain were half sparse, the barbarians under the mountain continued to remain in a state of confusion. The "Meteor Bullet" may not be a threat to the protected armored soldiers, but it is really effective against these brute soldiers with the upper body. The iron binding and lead pellets swept over one by one, and the flesh and blood of the middle were blurred, even if they were barbarians with big nerves and were not afraid of death, they also had fear.

Liu Wenbing was very proud, and he thought in his heart that next time he must change the shooter to iron, then it would be foolproof.

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

Liu Wenbing subconsciously followed the elephant to move, and at this time, the guide suddenly pointed to the rear and exclaimed:

"Barbarians, back, back, barbarians are coming from behind."

Liu Wenbing looked up, mom, there are several brute soldiers drilled out of the grass, and they are also the upper body**, but the spears in the hands of these brute soldiers are all equipped with iron spearheads, it seems to be elite soldiers! Depend on! They actually came to carry out sneak attacks.

At this time, the two elephant riders did not know where to run, and more brutes appeared in the grass.

At this time, another projectile was scorched, and only one projectile was still barely firing "meteor bullets", but as soon as the firepower was weak, one was lost, and the barbarians under the mountain immediately rushed up with a wild scream.

Liu Wenbing said in his heart, it's over.

A brute rushed up, but he didn't notice that there was also a barbed wire fence behind him, and he pounced too quickly. Immediately hung on the barbed wire barb, ripped off a piece of flesh, and immediately blood poured out. However, this brute soldier was agile, like a spirit monkey, and as soon as he hit the trunk of the tree, he turned over, and rushed to Liu Wenbing.

Liu Wenbing was shocked and frightened, and shouted hysterically in his mouth:

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

He raised his sword and pounced.

At this time, there is no way to retreat, and Liu Wenbing can only fight hard.

The brute raised his spear and stabbed, Liu Wenbing wanted to avoid it sideways, but unfortunately he was a step too slow, and the spearhead pierced directly into his right chest.

"It's over, is it just dead!"

Liu Wenbing closed his eyes in despair, feeling the violent impact almost knocking him unconscious, but his right hand subconsciously waved the knife, feeling that something had been cut.

Aren't you dead yet?

As soon as he opened his eyes, a brute fell in front of him, cowering on the ground and twitching, the knife in his hand dripping with blood.

I killed someone!

Liu Wenbing was stunned, and two barbarians surrounded him and raised their spears to stab.

Fortunately, Bai Er shot a puff of crossbow arrows in time, and puff puff, he saw two crossbow arrows nailed to the face and chest of the two barbarians, and they turned over and fell.

Ma Fen shouted:

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

Liu Wenbing suddenly woke up to the fact that he was wearing an iron cuirass, and ordinary iron spears could not hurt him. As soon as he thought of this section, his courage suddenly increased a lot, and at this time, he didn't care about the injury of his left arm, and rushed to the brute soldiers who came out, just picking up his knife and slashing indiscriminately.

The crossbow in the white second hand is one of the two cylindrical repeaters, the cylinder is loaded with thirty crossbow arrows, facing a group of brute soldiers from behind, Bai Er's hands are linked, more than 20 crossbow arrows are shot out continuously, and seven or eight sneak attack barbarians fall to the ground.

Liu Wenbing raised the knife and the sand and the sand and the swords, and the swords were eaten and the swords were eaten and the swords were blown

"Shoot, shoot these damn monkeys!"

Bai Er quickly changed a cylinder full of crossbow arrows, buckled the mechanism, and puff p

Dare to love this repeater is really a god! It's just a comparison with the submachine guns of later generations, Liu Wenbing said in his heart, this is fucking better than our "meteor bullet"!

Bai Er grinned:

"I said, this crossbow is still easy to use, happy!"

Bai Er was talking to himself proudly, and in the blink of an eye, he changed another quiver, buckled it, and shot it again.

When he shot to the fourth one, he suddenly got stuck, and Ren Baier didn't react no matter how much he played with it.

A brute soldier took the opportunity to rush in front of Bai Er, raised his spear and stabbed him, Bai Er flashed in a hurry, and was stabbed in the thigh. Bai Er was furious, pulled out his dagger, and stabbed the opposite brute in the chest.

Liu Wenbing lost Bai Er's crossbow fire support at this time, and immediately fell into the siege of the barbarians, but Liu Wenbing didn't know where the courage came from, and while resisting, he also reminded:

"Bai Er, change another quiver."

Bai Erfang's quiver should have been squeezed flat or something, the crossbow arrow was stuck and couldn't be shot, and it might work to change one.

Bai Er was reminded, and hurriedly changed a quiver, and sure enough, he could shoot arrows again, this time he saved Liu Wenbing again, Liu Wenbing was stabbed several times by a spear, fortunately, these barbarians were a little bit of a dead reason, and they chose their chests and lower abdomen to greet them, but Liu Wenbing relied on the cuirass to resist, although his chest turned over the river and the sea, he still did not fall after all.

Now the barbarians and horses in front of them are also close at hand, at this time the Zhuge repeater and the cylinder repeater began to might, at a distance of more than ten meters, the continuous firepower of the crossbow was unstoppable, and more than a dozen barbarians were shot at once.

However, the loading process of Zhuge repeater is too cumbersome, and it can only be thrown aside after shooting once, and only another cylinder repeater can quickly replace the crossbow arrow and quiver, so Ma Fen had to bite the head, outnumbered, and began melee hand-to-hand combat.

After a hand-to-hand fight, five special training soldiers were killed one after another, Ma Fen and the rest were all wounded, and when they were about to be buried in this small hill, they finally waited for the reinforcements brought by Wang Feng.
