Looking at the combination lock in front of him, Lin Yu could only stare dryly, and Lao Cheng had no choice, helplessly, Lin Yu could only use the death method - wait.

Wait until someone comes out, and then take the opportunity to sneak in, that's the way to die.

There was a lot of waste, and Lin Yu hid behind a large cardboard box and stared at it.

I have to say that sometimes the more unreliable it is, the more reliable it is, it can be reliable once.

After waiting for less than ten minutes, Lin Yu heard the sound of the mechanism activating.

I saw that the barrel suddenly began to move to the right, revealing an entrance to the underground, and at this time, a man in white overalls walked out.

"It's now!"

Seeing that the man was about to close the entrance, Lin Yu quickly rushed over and knocked heavily on his neck, the man obviously didn't react, so he fainted, and it was estimated that he didn't know what was going on.

"Haha, good luck."

Lin Yu smiled, looking at the entrance, Lao Cheng also felt that today was going well, and his originally nervous mood gradually relaxed.

"Go down, but be careful, it should be dangerous down there."

Lao Cheng admonished, Lin Yu did not relax his vigilance, looked at the dark underground passage, took a deep breath, and walked down.

The passage was very long, extending downward, I don't know how many meters it was already underground, when Lin Yu turned a corner, he finally saw a bright light.

"It looks like it's here, I need to be careful not to be discovered."

Lin Yu whispered.

"Well, don't be impulsive, or you'll ......"

Before Lao Cheng's words were finished, he suddenly lost his voice, Lin Yu screamed a few times, but did not answer, and then Lin Yu discovered an embarrassing question.

In this underground, there is no signal......

"Daddy!"

Lin Yu felt very helpless, no wonder the thermal induction mode couldn't find the life underground when he was outside, Lin Yu always thought that there was something underground interfering with the thermal induction, but now it seems that he thought too much, and the reason why he couldn't find it was as simple as that - there was no signal.

To be honest, without Lao Cheng's assistance, Lin Yu became nervous and hesitated to quit, but after thinking about it, he decided to move forward.

"Whatever, if he quits, how will he avenge his parents in the future, on!"

Thinking like this, Lin Yu sped up and cautiously walked over while observing the surrounding environment.

"Oh my God! How the hell was this built? ”

When he really walked out of the passage, Lin Yu was stunned, everything in front of him made Lin Yu suspect that it was on the ground, because it was too big, this was a huge factory, how big Lin Yu didn't know, anyway, he couldn't see the head at a glance, only the houses, all of which were bungalows, and they were probably the workshops of the factory.

Lin Yu didn't understand, how could there be no news from the outside world for such a big project, and what method was used to build such a large underground factory without being discovered.

Maybe it's too late, these workshops are closed, but you can see the large machines inside through the cracks, but you don't know what these machines are used for.

At this moment, Lin Yu vaguely saw that there were still lights in a hut in the distance, and Lin Yu decided to take a look.

Slowly approaching, Lin Yu carefully observed the surroundings, did not see any cameras, breathed a sigh of relief, and came to the hut.

"What's the matter with me?"

A slightly hoarse voice came from inside, and Lin Yu circled around the room, came to the window, and looked inside carefully.

I saw two men in black sitting facing each other, one of them was bloated, fat-headed and big-eared, more than 200 pounds, and the other was a little strange because he was wearing sunglasses.

"Is it cool to wear sunglasses on this big night?"

Lin Yu complained in his heart.

"I just got the news that the military has discovered this place and has sent a unit over."

The fat man said.

"The military? Does the government know about the mutants? Lin Yu thought about it, but felt that this was a good thing, with the intervention of the government, this matter would be much easier, Lin Yu had considered telling the police about it before, but Lin Yu always remembered his father's words before he died, but he didn't understand why his father didn't let him tell the police.

"Oh, I already know, I was planning to evacuate yesterday."

Said the man in sunglasses.

"So that's the case, no wonder there are no people above or underground, they have all been evacuated."

Lin Yu thought to himself, and at this time, the man suddenly sneered, and said, "But I can't let them come for nothing, this time I specially left them a big gift!" ”

"What do you want to do?" , the fat man was stunned.

"What? Hum! I've worked so hard to get to this scale, and now I'm going to give up here, so I won't be so cheap for them! Today, I want to let them know how powerful my purple pupils are! ”

"But it's not an ordinary army this time!"

Purple Pupil snorted and said, "So, it's them, which element is coming?" Potassium? ”

"No, it's helium!"

When she heard the word "helium", Zitong was silent.

Lin Yu outside was confused, what "potassium", what "helium", so that he thought he was reciting the periodic table, no, it seems that the purple pupil also asked, "Which element is it?" Well, that's the periodic table......

After being silent for a long time, the purple pupil actually smiled and said, "Helium?" You really look up to me, it seems, it's going to be real! ”

"You're going to make a move?" The fat man frowned.

"No, I still have a task, and I can't waste time here."

"You mean, B-class?" The fat man said

Purple Pupil sneered and did not speak.

"B-class? What is it? Lin Yu had a little headache, he couldn't understand what these two people said at all, and just when Lin Yu was about to continue listening, he suddenly felt a cold neck, and a stream of liquid flowed down his neck.

Lin Yu stretched out his hand and touched it, and then he was startled, this liquid turned out to be the bright red blood, and the rich taste stimulated Lin Yu.

Lin Yu looked up, and what caught his eyes was a pair of bright red pupils, a hideous face, and blood-stained fangs, which was a vampire bat.

When the bat saw Lin Yu looking at it, he immediately screamed, and the two people in the room heard the cry and immediately realized that there was an intruder.

"Oops, found out!"

Lin Yu gritted his teeth and immediately decided to evacuate, now that the people here have been transferred, and the military troops are coming over soon, there is no point in staying here, and now that it has been discovered again, it is better to withdraw first, and leave it to the military here.

However, the idea is good, but often the reality is so cruel, just as Lin Yu was about to leave, the familiar figure appeared in front of him again.

"Mud Horse!"

Lin Yu couldn't help but burst into foul language at this time, wasn't the figure in front of him the werewolf who had never been discovered?

At this time, Purple Pupil also walked out.

"Do you really mean that Cao Cao Cao arrived, and you helium people are in such a hurry to send them to death?"

"This time, it's really dangerous."

Lin Yu smiled bitterly.

At this time, the purple pupil took off his sunglasses, and then Lin Yu understood why this man's name was purple pupil, his pair of pupils were completely different from human pupils, and when he looked at it, Lin Yu seemed to be stared at by a cold poisonous snake, this is the snake's pupil, but the difference is that it is purple, purple pupils!
