Six Hundred and Ninety-Three Fire Propulsion

Although Xiao Yuan knew that there were bugs in the underground lake, he did not jump into the lake and was not very impressed by the lake bugs. He did not think of this for a moment, but he soon thought of the layers of insect sloughs on the lake shore.

Such a large cave must have an independent cave ecosystem, but so far, apart from wolf worms, only lake worms have been found in the cave.

Wolfworms are the absolute dominant creature in the cave, and there is no evidence that wolfworms have symbiotic habits. In addition, there is an underground river in the hatchery. All factors combined, it is very likely that the lake worms are wolfworm larvae. At 80%.

Time passed slowly as the two people communicated. After a while, the thirty-minute time limit ended, and there was still no response on the radio.

"The time has come." Ye Han's mood suddenly became much heavier. He raised his head and looked around, his eyes stopping on Xiao Yuan. "Let's get started."

"Yes!" Xiao Yuan answered simply and neatly, waving his arm forward, and two fully armed combat groups immediately rushed into the left fork.

Most of the members of these two combat groups had just followed Ye Han deep into the ground not long ago. Under the leadership of Xue Ju, they would advance along the previous route until the nuclear bomb was sent to the underground cave hall.

The figure of the last warrior left Ye Han's sight, and he shouted out of habit: "Ou..." After shouting one word, he remembered that Ouyang Ping had already set off with Xue Ju, and couldn't help laughing at himself, and turned to look at Xiao Yuan, " You arrange it."

"Yes!" Xiao Yuan grinned, wanting to laugh but not daring to be bold. He waved his hand and pointed at the wall of corpses, "Explosion team, enter!"

The demolition man immediately carried the explosives and ran under the wall of corpses. He knelt down on one knee to place the explosives. It only took a few seconds to install the explosives prepared in advance. The demolition man immediately stepped away and made a concealed gesture to everyone. .

Everyone immediately retreated. The Demoman raised three fingers, waited for a moment and lowered them one after another. The last finger fell down, and he clenched his fingers into a fist and waved lightly.

There was a muffled sound, and the wall of insect corpses blocking the entrance of the cave was destroyed in the explosion. The aftermath also shook the insect swarm behind the wall. The wolves on the ground staggered around, and the wolves on the wall fell down with crackling sounds.

Xiao Yuan waved his arm again: "Assault team!"

The three team members came out of the crowd. The two armored cannons in front were used as shotguns. They did not put the butts on their shoulders, but held them on their waists. There was no need to aim at all. They just fired bang by feeling, knocking out the stunned wolf. The insects were knocked to the ground one by one.

Their two armored guns are different. Apart from the longer barrel, there is not much difference in appearance. The biggest feature is that they do not use magazines to feed ammunition, but use ammunition conveyor belts like Gatling guns!

The conveyor belt is connected to the ammunition box on the back. The ammunition box contains 480 rounds of artillery shells. The firepower is much more sustained than ordinary armored guns. If necessary, it can fire continuously like an assault rifle.

However, the recoil of the armored gun is relatively high, and its weight is relatively low. It is extremely difficult to control the muzzle of the gun when it fires continuously. Therefore, the soldiers who use this weapon prefer single-shot shooting and rarely use continuous fire.

In addition, there is usually only a battery pack behind the armor. When this set of equipment was originally designed, a space for the battery pack was left in the middle of the ammunition box to facilitate soldiers carrying the ammunition box.

However, the designers soon discovered that the thickness of the "backpack" of the ammunition box designed under this idea was the length of the battery pack plus the artillery shell, so it was very heavy. In addition, the weight of the shells in the box is very high. The center of gravity of the armor behind the heavy ammunition boxes on the soldiers' backs is tilted backward. In order to balance the load, they must lean forward.

The designers stayed up late to solve this problem, but the several solutions they came up with were all unsatisfactory, and even slowed down the design of this equipment until they came up with the final solution - integrating the battery pack into the ammunition box , make room for the cannonballs!

The ammunition supply system of the ammunition box itself requires electric drive. After redesigning the integration plan, the design team finally came up with a practical design to control the center of gravity within an acceptable range.

This solution not only solves the problem of ammunition supply for armored guns, but also becomes a design template for other heavy armored weapons. Currently, all weapons and equipment that need to be carried on the back,

They all use integrated batteries to save space.

After killing the stunned wolves, the two team members stepped into the cave and opened fire while advancing, knocking down the attacking wolves one by one.

The wolves, which had no fear at all, rushed forward one after another. Not only did they run wildly on the ground, but some impatient insects also climbed up the stone walls and the roof of the cave, like water gushing overflowing from the pipes.

There were so many wolves that it was difficult to eliminate them with just two armored cannons.

At this time, the riflemen blocking the front would separate to the left and right to make room for their companions to shoot. The soldiers with grenade launchers behind them would smash several high-explosive grenades at them one after another, which could clear at least seven or eight meters of fire. aisle.

The three people work closely together to eliminate the bugs and open up a path.

The others followed them all the way with insect corpses on their feet. After advancing more than a hundred meters, the team arrived at the first cave hall on the road.

At this time, the cave hall was already crowded with dense wolves, and the assault team was a little frightened by the large number of wolves, so they had to huddle at the entrance of the cave to avoid the sharp attack.

The firepower intensity of the firepower team is limited. The space in the narrow hole is limited, and the insects they face are also limited. The firepower team has the advantage.

However, a large number of bugs are huddled together in the cave hall. If anyone dares to step into the cave hall, bugs from all directions will swarm up and launch an all-round three-dimensional attack.

The two infantry gunners once again gave way to the firing range, but in this situation, high-explosive bombs had very limited effect. The soldier immediately quit the high-explosive bombs, replaced them with incendiary bombs, and emptied the drum with a few bang bang bang bangs.

There were several blasts in succession, and the blazing flames burned blazingly.

The vitality of wolves is very strong. A dozen wolves shrouded in incendiary bombs instantly turned into insect-shaped torches and ran around in the cave hall with flames all over their bodies. It took more than ten seconds for them to die. through.

One of them rushed towards the fire team and was shot by two rifle gunners. It exploded into sparks all over the sky.

The area of ​​the cave hall is limited, and the high temperature generated by the six incendiary bombs caused the insects to scurry. The insects in the cave retreated like a tide, leaving only the burning insect corpses in the cave and billowing smoke.

The situation is excellent. As long as the incendiary agent is exhausted, the team can continue to move forward.

However, Ye Han and others discovered that the visibility in the cave dropped rapidly due to the smoke generated by the combustion. The armor's breathing equipment automatically cut off the external air and opened the built-in cylinder to release oxygen.

If it is an army version of armor, the way to deal with it must be to turn on the filtration system.

Ye Han suddenly remembered something and looked towards the cave hall. He saw that a large amount of thick smoke had accumulated on the top of the cave hall. The smoke had already rushed into the large and small caves connected to the cave hall and was spreading in an unknown direction.

Wow haha, everyone says it’s a boy, is it true that the system defaults to a girl?
