Zhang Xiaoshi's spiritual power swept away, and he found that there was a long downward staircase passage inside the small door, he immediately let the clone enter first, and he followed later, and the small door was destroyed by him. Pen, fun, and www.biquge.info

The downward staircase can only accommodate one person, there are about 100 steps, Zhang Xiaoshi estimated, about 20 meters high, the passage gradually widened and flattened.

"This is the sewer, and it seems that this underground laboratory uses part of the city's sewers." Zhang Xiaoshi had a powerful flashlight in his hand, and after scanning the surroundings, he found something.

It's just that one end of the sewer is closed, and the other end leads into darkness. Zhang Xiaoshi walked forward unhurriedly, infiltrating the surrounding walls with his mental power as he walked, checking the anomalous places.

After about a hundred meters, the other end of the sewer appeared, which was also closed, but now a hole appeared in the wall, and near this end of the wall, there was a smaller fork that led to the depths.

Zhang Xiaoshi's doppelganger had already entered the fork in the road, and after walking dozens of meters away, there were some steps leading to a height of more than three meters, where there was a gray iron door, but now it was twisted and deformed, and it was violently slammed open from the outside.

"It should be that a demon came in through the sewers, and then found the underground laboratory, no wonder there were only a few scientific researchers left in the previous life to live for more than a year, it turned out that it was not only because of food and electricity, but also because of a demon who entered the underground laboratory."

Zhang Xiaoshi found traces of demons from the traces around him, and immediately thought of a lot, and began to be vigilant, he didn't know how many demons had entered, but he believed that there were definitely many more surviving scientific researchers in it than in his previous life.

"How..................

Sure enough, after another mile, there was a roar of demons in my ears, and the dull sound of a strong impact on the iron door, apparently a demon had discovered the survivor and was hitting the closed iron door.

The isolation door of this kind of underground laboratory is generally a very heavy iron door, which either relies on electricity to open, or has a wheel-shaped bolt inside, and if you want to destroy it with violence, even a fourth-order demon can't do it in a short time.

Zhang Xiaoshi immediately rushed over, passed through a few corridors, and after turning a few corners, he found that four or five demons had gathered together, and it was only a third-order great demon, who was destroying an iron gate, and now the iron gate was a little deformed.

If Zhang Xiaoshi doesn't appear, I'm afraid that in half a day, these demons will be able to destroy this iron gate, and if there are scientific researchers hiding inside, then they can only become food for these demons.

These scientific researchers hid underground, although they were very lucky when the demons came and escaped the catastrophe, but they also lost the opportunity to evolve, because when the demons came in, they were at least second-order demons, and without the first-order demons to provide primary evolutionary energy, they were afraid that no one would be able to become awakened.

"Whoosh ............"

Several silver rays of light flashed past several demons, they let out a howl, and then they all fell, and as the silver light flew back to Zhang Xiaoshi, their blood crystals also flew towards Zhang Xiaoshi.

Zhang Xiaoshi walked unhurriedly to the outside of the iron door, there was still a dim light, it is estimated that the people in the laboratory have adjusted the lights everywhere to the darkest degree in order to save power.

"Is there anyone in there? I'm here to save you, the demons outside have all been killed, open the door. Zhang Xiaoshi found that there was a camera above the iron door, and immediately raised his head and said inside.

At this time, in the closed area of the underground laboratory, there were still twenty-eight surviving scientific researchers, but because of the demon invasion, they were also isolated in more than ten laboratories, but because there was still a power supply, everyone was still able to talk and video

Just as they kept learning that there were demons who had destroyed iron gates one after another, killing and eating their companions, many people were desperate, and there were even cases of scientific researchers committing suicide and madness.

They have lost contact with the outside world, and it is not known if the whole world has changed, or if only the underground laboratory has been invaded by demons.

They hoped that it would be the latter, and then the company would eventually discover the anomaly in the underground laboratory, and eventually the country's army would come to rescue them, but as nearly half a year passed, they did not wait for the rescue, nor did they contact the outside world, so they felt that something might be wrong with the outside world.

On this day, when many researchers were usually bored, they suddenly heard a frightened cry for help from Lab 19, it turned out that Lab 29 had been discovered by the green-skinned monster.

They originally thought that the two companions of the 29th would probably be like those companions before, and in half a day at most, they would be broken into the door by those monsters, and then killed and eaten.

In Laboratory No. 29, two young researchers hugged each other in fright, each holding a weapon found in the laboratory, and his heart was full of fear while longing for a miracle.

But just then, they noticed that the picture in the passage outside had changed, a few flashes of light flashed, and the monsters had fallen, and then a young man walked up to the camera and told them that he had killed the demon to save them.

"Click............"

The two young researchers in Laboratory 29 were already scared to death, but they didn't expect such a reversal, they immediately turned the camera, and sure enough, they saw a lot of monsters on the ground, and a lot of blood flowed out of their bodies, and standing next to these monsters was a young man like them.

"Bang Dang ............"

The two young men cried with joy, and then scrambled to open the iron door, because the iron door had been deformed, and after they opened the wheel bolt inside, the iron door was a little stuck, and Zhang Xiaoshi told them to retreat, and then kicked the iron door open.

"Congratulations, you've been rescued." Zhang Xiaoshi looked at the two young men in the laboratory who were looking at him with some trepidation, grinning and said.

"Are you sent by the government to save us? How's it going out there now? How many of you came? A young man asked hesitantly.

"I wasn't sent by the government, I'm here to save you. And I was alone, not anyone else. As for the news outside, I guess you don't want to know, but I have to regret to tell you that it is the end of the world outside, and there are demons everywhere, demons that are more powerful than these demons. ”

Zhang Xiaoshi said as he took out some food and water and handed it to the two of them, and they devoured them quickly, because the food in the underground laboratory was limited and it had been controlled.
