After dinner, Chen Xing returned to the underground and continued to command. But he was busy all day, a little tired, and fell asleep while waiting for feedback.

"Commander, wake up, there's a situation!"

In the middle of the night, he was woken up by a hurried voice to learn that he had encountered a corpse during his exploration, and had lost three soldiers, and that the corpse was crawling towards him. Chen Xing immediately made a decision, ordered a retreat, and notified the mecha team outside to prepare for an artillery bombardment, and as soon as the corpse appeared, it would be blown to pieces.

"Hurry, hurry, hurry!"

After receiving Chen Xing's order, the mecha pilot quickly got up from the tent, opened the hatch, climbed into the cockpit, flipped the switch, and lit the screen. The logisticians ran back and forth, constantly stuffing shells into the magazines behind the mechs.

"Loaded!"

With the order of the captain of the mecha team, all the mechs carrying mortars on their shoulders made a "clucking" sound, which was the friction sound of cannonballs pushing into the chamber.

Immediately afterward, there was silence. The beam of the searchlight was concentrated at the mouth of the tunnel, sweeping in a small area, and everyone held their breath and stared at it.

I don't know how long it took, but the ground suddenly bulged. In the incandescent beam, a pile of eroded pieces of flesh appeared, and countless faces twisted on the pus-stained surface, slowly wriggling.

"Knock knock!" "Knock knock!" "Knock knock!" "Knock knock!"

In the next second, ten mechs opened fire at the same time, and the cannonballs whizzed away, exploding around the corpse. Suddenly, the earth rushed into the sky like a fountain and rained down.

"Hit, fight again!"

Before the smoke cleared, Chen Xing issued the first round of orders. In his previous life, when he was in the Thunder Light Regiment, he had encountered several corpses, and he had seen their tenacious vitality, which could never be solved by a few shells.

This was followed by several rounds of shelling, until the barrel became red and needed to be stopped.

Chen Xing tensed his nerves and didn't dare to relax. Suddenly, a sharp roar sounded in the smoke, and Chen Xing immediately fell to the ground. The sound of breaking the sky fell into the mecha group from far to near.

Turning his head, a mech was emitting a large amount of white smoke, writhing uncontrollably, sparks and arcs bursting from its joints, and a terrible wail came from the cockpit.

"Hands, my hands! Help, ahhh ”

But in the blink of an eye, when the smoke cleared, a huge lump of flesh appeared in the beam of the searchlight again. Although the surface was charred and dripping with pus, it did not appear to have been fatally injured.

Chen Xing quickly scanned it with the black watch.

[Corpse Nightmare (Normal)]

[HP: 707/914]

[Talents: Body Regeneration, Acid Spray]

[Negative trait: Slow to act]

[Virus Likely to Carry: Living Corpse Disease]

Unexpectedly, several rounds of shelling only caused it more than 200 points of damage, which was too difficult to deal with.

Just as he was worried, the white-robed old man standing on the high ground suddenly stretched out his hand and grabbed it, and a spear appeared out of thin air. The body of the spear was as black as ink, cold and heavy, but the tip of the spear seemed to be burned by fire, and it was extremely red.

I saw the old man throw his spear, grab it with his backhand, jump into the air, and throw it.

"Drink!"

A burst of red light shot out, piercing through the corpse in an instant, and then the fire flashed and exploded. The dazzling light is like the rising sun.

The corpse was blown to pieces, and the ground was littered with wriggling pieces of flesh. Chen Xing immediately waved his hand and ordered the launch of an incendiary bomb. The soldiers and mechs quickly swapped out liquefied fuel bombs and threw them at the corpse's shredded flesh.

The flames suddenly rose into the sky, and the smell of burnt meat filled the air.

The old man landed on his feet, his face was flushed, and he took several deep breaths before he recovered, and it seemed that this shot had caused him a lot of damage.

"Third uncle, your Great Day Breaking Demon Spear has improved again." Ye Yang Qingyan said in surprise.

"Congratulations to the third uncle." Ye Yang Bailiu said.

"Hehe~" The third uncle smiled slightly, waved his hand and said, "I'm old, it's not good, it's up to you in the future." ”

Moments later, the flames were extinguished, and Hook led the men to clear the battlefield. It didn't take long for a walnut-sized green crystal to be delivered to Chen Xing.

The tunnel was smashed by a series of shelling

[Intermediate Toxin & Energy Crystals (Nightmare), approx. 26g]

[Market Valuation: 1300~1320 Gold (World Bank)]

Although it is worth a lot of money, almost 50 gold coins per gram, it is still a loss, losing one Art6, three lives, and a large number of incendiary bombs and shells.

After cleaning up the battlefield, Chen Xing sent someone to give the corpse crystal nucleus to Ye Yang Qingyan, and she distributed it uniformly. Next, because most of the tunnel was blown up by shells and needed to be re-dug through, Chen Xing had to return to the water station to rest.

The next morning, just after dawn, he returned to the underground and continued to direct the exploration.

The underground survival site is composed of five parts, namely the living area, the manufacturing area, the power generation area, the planting area and the resource recovery area.

The living and growing areas are on the top floor, the middle floor is the manufacturing area and the resource recovery area, and the bottom floor is the power generation area. Most shelters are sustained by geothermal power. The heat energy is converted into electricity by a steam engine, which is then used for various types of production.

Electric light can provide plants with the energy needed for photosynthesis, electrolysis technology can break down all kinds of garbage, it can be said that electricity is the lifeblood of survival, and power outages mean death.

At noon, the expedition found a high-ranking officer's quarters and harvested a collection of souvenirs, including a saber that symbolized status, medals for war exploits, exquisite pistols, gold bars, clocks, jewelry, and various handicrafts.

Roughly estimated to be able to sell more than 100,000 gold coins, Chen Xing secretly hid two gold guns, a pocket watch and three major bronze medals, and handed over the rest. His private collection accounts for about 5% of the total value, even if the third uncle and Ye Yang Qingyan know about it, they will turn a blind eye, after all, he has also contributed a lot of manpower and material resources.

On the evening of the third day, the expedition finally entered the manufacturing area. The passage is much wider, with pipelines and tracks on the ground, and old rail cars can be seen from time to time.

The people of the Survival Center manufacture and repair all kinds of equipment here, as well as produce weapons and medicines. Some of the Survival Centers are also connected to the pre-cataclysmic subway tunnels, allowing them to trade with other Survival Centers.

However, in the future, due to the long years of underground life, some people have developed lesions. In order not to be infected, most of the survival centers cut off contact.

The rooms in the manufacturing area are very large, and all kinds of large-scale production equipment are installed, but they are not very valuable, and can only be used as scrap metal to make steel.

"Commander, we've found traces of some kind of large creature."

An expedition team discovered several giant holes several meters in diameter, unlike those made by humans. Chen Xing went to the scene to check and found that there were still some traces of high temperature burning around him, and he soon thought of the steam silkworm.

The size of the steam silkworm matches the size of the hole, and where the high-temperature rays pass, it will form a line-like burning mark. By all signs on the surface, the steam silkworm came here, and then dug a hole and left.
