It took about three or four minutes for the temperature in the bunker to slowly return to normal.

Feeling that the air around him began to flow again, Wang Wuyun took off his oxygen breathing mask.

Xue Qianyan, Yu returned to the field, and Ma Yang also took off his breathing mask one after another.

Xue Qianyan's face was normal, and she brushed her hair after taking off her mask, while Yu Guitian and Ma Yang were a little pale and sweaty on their foreheads.

People who have not seen the terrifying power of cloud burst bombs or air bombs, the first time they have experienced it personally, they will inevitably be shocked by the power of that weapon, just a few minutes, Wang Wuyun is okay, quite calm, he knows that with the protective power of this bunker, there should be no problem, this should be considered when it is built, but those few minutes are a kind of torment for Yu Guitian and Ma Yang.

"This place, it's really not human, these damn insects, can't you fight on the ground, you have to fight ...... here" Xue Qianyan muttered.

The agitation outside the bunker a few minutes ago had completely disappeared at this time, and there was no sound coming out of the bunker again, as if it was in a desert with no people.

Yu Guitian stretched out his hand to pull the protective steel plate of the pillbox perforation, and as soon as he touched it, he screamed and quickly retracted.

"What's wrong?" asked Wang Wuyun.

"Be careful, the handle of this protective steel plate is hot, and it needs to be cooled with water...... "Yu Guitian reminded.

The water used to cool the barrel of the machine gun in the bunker was poured on the protective steel plate, and the protective steel plate made a sound of water vapor, which almost felt like it was splashed on an electric iron.

When the protection in front of him had just cooled down, Wang Wuyun pulled away the protective steel plate in front of him with a bang.

Smack......

The severed claw of a completely charred, smoking man-eating insect fell in.

Yu Guitian and Ma Yang were startled, and only after seeing what it was that they were relieved.

The severed claw of the man-eating insect was telling the horror of the outside of the bunker just now

A few flares flew into the air again, Wang Wuyun looked outside, the scene of the cave **, like looking at the forest after the fire, as far as the eye could see, everywhere was scorched black, the smoke curled, the rock gap in front of him and the wide gap within the reach of the bunker machine gun fire, there was hardly a complete man-eating insect, and the knife beetle that gave people a huge deterrent before only left a broken shell, like a fossil that had weathered here for thousands of years, standing in a desolate but scorching mess.

Wang Wuyun heard the sound of gasping cold air from Yu Guitian and Ma Yang beside him.

An explosion of this magnitude, the one that was dropped just now, may have more than one air energy bomb, and if someone was outside just now, the probability that that person would survive was almost zero.

"Great, we repelled the attack of those bugs?" Yu Guitian and Ma Yang were happy and high-fived each other in celebration.

"Although the man-eating insects have died a lot, the minefield we have laid out outside has also been leveled by those man-eating insects......" Wang Wuyan's sharp eyes scanned the cave outside the bunker, turned his head, and poured a scoop of cold water on the two, "Immediately clean up the fortress, replenish ammunition, and be ready for the next battle ...... at any time"

"Yes!" Yu Guitian and Ma Yang stood upright, and then immediately began to get busy.

The two quickly cleaned the bullet casings inside the fort, pushed them away on a manual trailer, and then went to collect new ammunition.

All the people inside the fortress were busy.

"Something is wrong...... Xue Qianyan walked over and glanced at the lifeless cave outside.

"Did you find out too?"

"Those bugs won't be so inexplicable to send them to death, this offensive rhythm is a bit wrong!"

"I think that's the same, did you find it, this attack, although there were also knife beetles, but the number of knife beetles, compared with the previous times, in terms of proportion, is significantly smaller, I think the purpose of this wave ......of attacks of these insects is just to clear the obstacles that rush to us, like what are you preparing for" Wang Wuyun said with a frown, his instinct to experience countless dangers told him that the crisis in front of him was not over.

In addition to instinct, as another proof that the current crisis is not over, is that until now, he has not received the hint of the Ten Thousand Tribulation Orb.

If this wave of the Zerg's attack is over, then the Ten Thousand Tribulation Orb will definitely remind him of the robbery points he obtained, just this wave he held on to the bunker, although it is not too dangerous, but there should still be thirty-four robbery points, the Ten Thousand Tribulation Orb did not remind, indicating that the current crisis is not over, which is also another use of the Ten Thousand Tribulation Orb discovered by Wang Wuyun.

Yu Guitian and Ma Yang quickly returned with an ammunition box and replenished some ammunition for the machine guns in the bunker.

Flares kept falling from the sky, illuminating the ground white.

On the surface, everything is fine, and no more zergs appear,

Wang Wuyun waited in the bunker for an hour, there was no movement outside, the nerves of Yu Guitian and Ma Yang had relaxed, and they felt that the Zerg might not come again, but Wang Wuyun's heart was always hanging, and the lingering sense of crisis followed him closely like a shadow, and it was getting closer and closer.

The cold hair on his body also reacted a little.

The murderous aura was not aimed at Wang Wuyun, so Wang Wuyun couldn't tell where the crisis came from, but Wang Wuyun felt that he couldn't continue to stay in the bunker and had to do something.

"I feel a little wrong, I'll go out and have a look!" Wang Wuyan picked up his ammunition box, picked up the dark roar, and said to Xue Qianyan.

"I'll go with you!" Xue Qianyan said without thinking about it.

"No, it's too dangerous, if you don't want to stay here, you can go up there for the time being!" Wang Wuyun said directly without thinking about it.

"What, care about me?" Xue Qianyan glanced at Wang Wuyun with a smile.

"Uh......" Wang Wuyun scratched his head, what he said just now, he didn't think much about it, and after saying it, he realized that he had unconsciously regarded Xue Qianyan as his partner, and began to consider the safety of the other party, "It's disgusting outside now, I guess you won't be too used to it!"

"What is this, isn't it similar to the man-eating insects that I roasted with electricity, don't forget that you still have to rely on me to protect you, let's go......" Xue Qianyan was the first to walk out of the bunker, and Wang Wuyan could only walk out behind her.

This underground fortification group has an entrance and exit to the outside cave and the battlefield, and the exit is convenient for people to clean the battlefield and lay mines, Wang Wuyun and Xue Qianyan have special identities, and they have the right to enter and exit the battlefield freely, after Wang Wuyan explained that he wanted to go outside to investigate, the officer who handled the entrance and exit directly asked his soldiers to open the thick door that was comparable to the door of the bank vault, so that Wang Wuyun and Xue Qianyan walked out of the fortification group and entered the cave.

As soon as they entered the cave, both of them put on night vision devices, and everything in the entire cave was a faint green color in the night vision devices, and they could see very clearly.

For Wang Wuyun, he may be able to see more clearly without a night vision device, but in order to pretend, he still put on the night vision device.

The cavern was littered with the corpses of mutilated man-eating insects, charred, turned to ashes, and some of the limbs remaining, everywhere, and the ground under their feet was still warm.

Wang Wuyun carried a full set of combat equipment on his back, climbed all the way along the rock wall of the cave and the terrain with the trend of the ridge, and spent more than ten minutes climbing directly to a high ground, carefully observing the situation between the cave and the rock gap below.

The fortifications were still shooting light projectiles one after another, everything seemed to be normal, the zerg in the cave seemed to have died down, and there was nothing strange, but Wang Wuyun just felt uneasy.

"There doesn't seem to be anything wrong...... Xue Qianyan said as she glanced at the open area in front of her and frowned slightly.

"We have a saying in Yan Futi, which is called striking grass and startling snakes, and now we can try it......"

"How do you try?"

Wang Wuyun took a burning stick that he was carrying, and pulled it open at once, and the burning stick burned, emitting red light, illuminating the surroundings, which was very conspicuous in the dark.

Wang Wuyun directly threw the incendiary stick at his feet, then took out the dark roar he was carrying, loaded it with a metal burst bomb, and fired three shots directly at the area where the man-eating insects were swarming on the battlefield just now.

The metal exploding bombs fired by the dark roar did not have a target, but flew scattered on the ground and in the rock crevices in an area of more than 1,000 meters to more than 4,000 meters, and exploded violently, and the flames were more than 20 meters high.

After firing three shots and making a huge movement in the cave, Wang Wuyun did not move, but stood with his eyes closed, as if waiting for something.

Just over ten seconds later, Wang Wuyun's eyes opened violently, looked at a place more than 1,000 meters in front of him at three o'clock, turned the muzzle of the gun, and banged it......

Three more metal bursting bullets comparable to artillery shells were fired, all accurately shot at the same place thousands of kilometers away, and the bursting bombs in front had just exploded a large crater more than two meters deep, and the bursting shells in the back were shot directly into the pit, continuing to blow up the big crater even bigger.

After the three bursting projectiles were ejected, the big crater on the ground was almost six or seven meters deep.

Just when Xue Qianyan was still wondering why Wang Wuyan was shooting towards a place.

Rumble......

The mud under the big pit that was blasted out by Wang Wuyan's metal blasting bomb flew up, and the rocks were splashed everywhere, and the ground around the entire pit for dozens of meters suddenly collapsed, revealing a black hole, and then countless insects poured out of the black hole, frantically rushing towards the fortifications and pillboxes thousands of kilometers away.

The insects, which were not very large, each one the size of a basin, looked like a round-tailed horseshoe crab in the sea, sticking to the ground and moving quickly.

"Melt the insect ......," Xue Qianyan exclaimed.
