When Team 16 returned to the main base, they saw that they were busier than ever, and it was thought that all the troops already knew that this insect plague was coming.

Lei Ming grabbed a pioneer team leader and asked, "Where are you going?" ”

The captain said: "There are a large number of insect swarms in Canyon No. 3, and we are going there to intercept them. ”

Zhang Heng saw Lei Ming chatting with the captain for a while and came back and asked, "Are they going to destroy the insect swarm?" ”

"Hmm."

"What about us?" Long Wu asked on the side.

"Let's go back and recuperate."

Team 16 soon returned to their barracks under the leadership of Lei Ming, and at this moment there were only a few teams in the camp of the exploration team that had returned, and the rest were either on their way back or had been ordered to go to the area that needed to be garrisoned.

"It's a brutal summer." Jason sighed as he looked up at the various areas displayed on the electronic display.

"You should be glad that if it was winter and came out to harass us, it wouldn't be the case now." Li Yi replied on the side.

"Don't be stupid, bugs are also deadly." Jason sneered, and when he saw Zhang Heng's doubts, he said: "We have been underground, so you may think that this insect seems to be active all the time, but in fact, the underground insect is like this." ”

"The insects on the ground will come out in the summer, after all, the temperature will be higher in the summer, and the area where they come out is also near us in a few big canyons or large mountain ranges."

Zhang Heng suddenly realized that he had been active underground for more than a year, and from time to time he encountered those insect swarms, and thought that the insects on the ground had also been active.

"Isn't that insect afraid of the harsh environment outside, after all, the air pressure is so low." Zhang Heng asked.

"So, the adaptability of these bugs is terrifying, even such a poor environment outside can reproduce so many numbers, if it is replaced by better conditions than now, I think the whole of Mars will be occupied." Jason sighed.

After resting in the camp for two years, Team 16 received the task of going to Cave 1 with Team 3 to garrison it.

Cave 1 is the largest cave that has ever been developed, and it is the largest arsenal and production base for various consumable materials.

Therefore, the importance of Cave No. 1 is self-evident, and Cave No. 1 is located at the mouth of a Grand Canyon, only 50 kilometers away from the Grand Canyon, and it is also the place most severely affected by the insect swarm in the previous insect plagues.

The cave that was originally so unfavorable should have been abandoned a long time ago, but because Cave No. 1 is very rich in mineral resources, and there are even extremely rare light armor materials in it, it has always been heavily guarded.

This time, in addition to the No. 3 and No. 16 teams, the No. 10 and No. 11 teams will also go here, and even the first five squadrons of the ground development team will also go here to garrison.

By the time the two teams arrived at Cave One, it had already fought with the swarm, and the road between the canyon and the cave was littered with insect corpses.

Zhang Heng looked out of the car window, and saw that Cave No. 1 was built with the mountain, and the entire 200-meter-high mountain had been converted into a metal fortress, which was covered with large various cannon ports, and a circle of firepower nets was laid every ten meters outside the mountain, and a full five circles surrounded here.

Towering automatic weapon stations and high-voltage power grids stand in dislocation with each other, and they are airtight.

"You see it's very well guarded, and I've almost missed it before." Lu You said when he saw Zhang Heng looking outside.

"Isn't it, it's going to be lost?" Zhang Heng said.

Lu You smiled: "Don't look at these insects, when the number of insect corpses is piled up to a certain level, if you don't have time to clean it up, it will be over." ”

When Zhang Heng heard this, he also remembered an underground battle, when the insects and corpses were so dense that people couldn't leave, and directly blocked his own people in the passage that had been built, and this passage was almost abolished.

"And not only are the bugs troublesome, but even this gas is also troublesome, if a hurricane passes by here, at least some of these defenses outside will have to be scrapped, and the bugs will fall from the hurricane, and then you can only come out to fight these guys." Li Yi added on the side.

Hearing these veterans discuss these previous wars, Zhang Heng also felt a lot of pressure.

Seeing that the team had come with supplies, the cave defense force opened the entrance and let the group in.

The supplies brought this time were mainly medical treatments, after all, the fighting here will be more severe than in other places.

After unloading the medicines, the transport force will reload the weapons from Cave 1 to be sent elsewhere.

As the transport force was about to leave, the swarm rushed out of the mouth of the canyon again, and at a glance, it was all black and wriggling.

The fortifications outside the mountain soon rang out, and the sizzling of various electric currents and the roar of missile launches shook the rumbling inside.

The barrels of the machine guns on the mountain also began to roar, knocking down most of the insects flying in the air, and the rest were also put down by people when they rushed to the top of the mountain, and some of the larger ones were killed by people in close proximity.

By the time this wave is over, most of it has passed.

After the transport convoy left, Zhang Heng and the others finally had time to rest and began to rest at the rest point.

For a few hours in a row, there would be several battles every time, and many people were tired, and there was no way, in such a situation, no one could rest well.

Other regions have also experienced a lot of fighting, some with heavy losses, and some with relatively large losses.

Not only will the swarms storm the human base, but there will also be battles between the swarms, and after the capture of some unguarded caves, the swarm will immediately start a civil war to seize the dominance of these things.

"According to reports from other regions, a new variant has been discovered in this insect plague." The garrison general of Cave One gathered several important teams and put the information he had just received in the conference room.

The insect that has never been seen in the projection is a bit similar to a large mites, with a huge abdominal cavity, but the limbs are more slender, and the abdominal cavity will not be close to the ground like a mite after standing up, but can bend freely at a certain angle.

The general pointed to a tube at the end of the abdominal cavity and said, "From the tube in this abdominal cavity can spew super corrosive liquid, and several of our cave gates have been missed by the attack of this kind of bug." ”

Everyone's face was gloomy when they heard the news, "Then how to deal with such a bug?" Lei Ming asked.

The general released another overhead picture and drew a few circles on it: "Look at this picture, the front circle is attacking, and the middle circle is like this, the number may be less than the whole swarm, but it is generally well protected, and often we put our forces in such a front and miss the middle group." ”

"What's more troublesome is that if you don't burn it directly, even if you knock down this bug, the body fluids in this abdominal cavity will corrode the ground, and there are a few caves that just happen to be burned to the passage, causing the swarm to rush through the passage and fall."

There was silence in the conference room, and the fall meant that the soldiers inside had little chance of surviving.
