After receiving the order, the two soldiers of the Ye Yang family came to the semicircular iron gate, stuffed the plastic explosives evenly into the crack of the door, then inserted the fuse, and handed the remote control to the commander Chen Xing.

Plastic explosives, also known as "C4 explosives", are pre-cataclysmic technologies that are detonated with a strong electric current. Because of its excellent performance, it has the characteristics of waterproof, high temperature resistance, strong scalability, and stable running height, so it has been used until now.

Chen Xing pressed the detonation button, and the fire flashed in front of him, smoke and dust gushed, and the explosion sound was deafening.

"Quack Quack ......"

With the harsh rust grinding sound, the huge iron door slowly fell. The beams of dozens of bright flashlights converged and swept back and forth.

The smoke and dust gradually cleared, revealing the scene inside. It is a small underground plaza with shops, fountains, leisure benches, sculptures, as well as sports facilities such as running tracks, basketball courts, swings, horizontal bars, etc.

"Split into two teams and explore in a carpet style."

This time, Chen Xing did not go into battle in person and stayed in the rear to command. Anyway, Ye Yang's family is wealthy, and it is nothing to lose some soldiers, so there is no need for him to risk his life.

After a while, gunshots and explosions were heard from inside. The team leader reports that he has encountered several slime monsters.

Slime monsters move very slowly, rely mainly on tentacles to attack, and as long as you keep your distance, there is no danger. The biggest threat to the slime monster comes from the Ebola virus it carries, and once the creature is infected, its internal organs will rot within a few days, turning into pus, and the mortality rate is extremely high.

However, the world's medical technology is extremely advanced, and the virus has been overcome, and it is only necessary to drink a can of comprehensive antidote to solve the problem.

The comprehensive antidote is the standard carrier of combat units, which can treat 73,649 viruses and neutralize 16,312 toxins, which is very similar to the "golden balm" on the earth. If it's not expensive, it's definitely a must-have for a home trip.

"Square West Security." "The east of the square is safe." More than ten minutes later, two reports came out of the walkie-talkie one after another.

"Found the west gate, is it open?" "Discover the east side passage, do you want to explore?" Requests followed.

"Come one by one, explore the east passage first." Chen Xing ordered. It's easy to get stuck at both ends when you explore two places at the same time.

A few minutes later, just as Chen Xing was drowsy and about to drink a cup of tea to refresh himself, on the other side of the underground survival center, in the jurisdiction of the Moore family in Raven City, in the darkness where he couldn't see his fingers, a huge mass of "carrion" was slowly wriggling.

Its surface is thick and erosive, like a severely purulent wound, and it is very disgusting. If you look closely, there are faces on it, humans, animals, and other unknown creatures.

Its body is full of bones, like a hell.

If there were mutant biology experts or experienced veterans here at this moment, they would definitely shout: "Corpse! ”

The Necro comes from the lowest level of the Temporal Undercurrent, a scavenging ring in the biological chain, feeding on the corpses of living beings. Unlike omnivorous abyssal termites, they only eat carrion. The way they eat is extremely simple and crude, and each cell of their body has its own digestive system, which directly wraps the corpse into the body, digests and absorbs, leaving a pile of white bones.

They are extremely regenerative and almost immortal, leaving only one cell alive. Moreover, their bodies are filled with acids that can corrode most metals, and the steel plates of the mechs are nothing in front of them, let alone ordinary protective suits.

"Boom!"

Suddenly, a dull explosion sounded in the darkness, and it instinctively contracted, shrinking its massive body several times over. Immediately after, beams of light shone through.

"......Shh

"Oh my God, what's that?" "Yes, it's a corpse!" "Retreat!" "Withdraw!" Within seconds, the voice became flustered.

At the same time, the corpse's body rapidly expanded, like a swollen balloon, and then let out a sharp whistle, spewing out a large amount of steam and shooting out streams of dark green liquid.

The soldier at the front could not retreat, and was hit in the head, and his body immediately smoked like a melting candle, turning into a pool of blood at a speed visible to the naked eye, and died in a very miserable state.

What's even more terrifying is that the corrosion of acid is progressive, starting with hair and skin, eyeballs falling, braincase exposed, muscle ablation, organ ulceration, bone and flesh separation, the whole process is like watching vivisection.

The air was filled with a pungent smell, and the soldiers were terrified and scrambled to retreat.

"Don't panic!"

A cold, silent voice rang out from behind, and a teenager paced out. He wore a black gown, combed his hair neatly, and was meticulous throughout his body.

"Woo woo woo ......"

The second eruption hit, and I saw him with one hand, and a translucent wall of ice appeared in front of him. The acid shot on it and slid down like a waterfall.

"Shoot!"

At the same time as the order was given, the boy stretched out his other hand and pushed it upward, and the ice wall immediately separated up and down, opening a gap.

"The young master is mighty!" "Kill it!" "Avenge your brothers!"

The soldiers, with their morale boosted, stepped forward, stuck their guns out of the gaps, and opened fire on the huge mass of flesh.

At about the same time, in the jurisdiction of the Yang family, a young man with triangular eyes led soldiers into the underground hall, and a fire dragon surged out, burning the living corpses in the path to ashes.

Behind them, stood a group of ragged homeless people. There are old and young, with fearful faces, and they will be pressed up as cannon fodder at any time.

Everywhere was exploring intensely, and Zhang Meng and Luo Shaoqing also joined the expedition.

And in the jurisdiction of the Shiraishi family, twin girls are sitting under the parasol, drinking black tea and eating snacks.

The young women of the gate lord family rarely go to war, and their main task is to marry, and their personal strength is used to ensure that the genes of the offspring are good enough. Just like Yeyang Qingyan and Yeyang Bailiu, they are not allowed to enter the underground.

At half past eight o'clock in the evening, Chen Xing returned to the ground for dinner. At present, it has advanced 300 meters to the research institute, and if all goes well, it will be able to advance to about 1,000 meters tomorrow morning.

The underground shelter is huge, like an underground city, with dense passages like cobwebs and many rooms, hiding all kinds of dangers.

Before he came up, he had ordered the ventilation ducts to be cleaned and repaired. The shelter has been out of operation for many years, and the oxygen gets thinner the further down, and fresh air needs to be brought in from the ground.

"Rest when you're tired, don't push yourself too hard." While eating, Ye Yang Bailiu whispered in Chen Xing's ear.

"It's fine." Chen Xing didn't think so, Ye Yang Bailiu was not angry, and continued to persuade, "The old man always says that the meal must be eaten one bite at a time, and the road must be taken step by step, and nothing can be rushed, but step by step, you know?" ”

"I'm definitely not the only one who has been working all night." Chen Xing said. He had already sent people to observe the perimeter of the other camps, and none of them had stopped.

"Okay, be careful, then." Ye Yang Bailiu said that he couldn't move him, so he had to give up.
