In the end of the world, the small dried fish is left behind!

After killing these butterflies, Tang Yu and Chu Lan began to stare at the changes in this piece of heaven and earth. Gradually, the sky here began to gradually fade from the original rich blue to white, and the range began to expand. Big, finally, from the sky to the earth, certain changes have taken place.

The space around Tang Yu and the others began to distort, and after a few races, this change began to stop.Tang Yu, Chu Lan, Lou Yu and Baozi came out from behind the bushes, watching the changes here in amazement.

The sky is no longer the sky. When I look up, I see a white ceiling. The ceiling here is very high, like a four or five-story building, but the plants on the ground have not changed, and the butterflies on the ground are still there.

It seems that Tang Yu and Chu Lan's judgments are not wrong at all, there are indeed strange things here, and the creators of these strange things are those butterflies.Not only are they poisonous, but they can also create illusions, making people feel like they are there. Most people would not notice it. If the bears and butterflies hadn't appeared, Tang Yu wouldn't have noticed if most of the butterflies had died and exposed the ordinary ceiling. It's these butterflies!

"Let's go, get out of here first, so that nothing will appear later." Chu Lan looked around vigilantly. If there were other animals appearing, it would be troublesome. After all, the movement of the bear and the butterfly was so loud just now. It's better to go first.

"it is good!"

Regardless of physical fatigue, several people quickly shuttled through the woods, but this time they came out of the woods very quickly.After they stepped out of the forest, they looked back at the forest, surrounded by iron walls, and in the middle was a forest. Obviously, this was a man-made forest, or a man-made forest as big as two football fields and four or five stories high. forest.

"It's finally out, have we been walking around in circles before?" Lou Yu couldn't help asking, looking at the criss-crossing paths in the man-made forest.

"Well, if it wasn't for those butterflies, it would still come out no matter how much you go around." Chu Lan replied.

"That's it..." Lou Yu couldn't help shaking, this place is really dangerous, if Tang Yu didn't find out, then wouldn't they have to wander around here and never get out?

"Don't look, come here and help me see how to open this door." Standing in front of a door, Chu Lan turned her head and shouted at Tang Yu who was still thinking and Lou Yu who was looking left and right, and the two came to Chu Lan's side in response .

Lou Yu looked at the lock on it, and after a while suddenly said, "I think I've seen this door before!"

"Have you seen it?" Tang Yu and Chu Lan looked at him suspiciously, especially Tang Yu. Although this kind of door is common in various laboratories, how could Lou Yu have seen this kind of door?

"Yeah. I still remember that when I was very young, my grandfather was very busy and couldn't take care of me, but he was afraid that I would have an accident at home, so he took me to his research institute, and the door there was like this! I remember It's very clear." When Lou Yu mentioned his grandfather, he looked nostalgic.

Tang Yu and Lou Yu didn't speak, but went over to pat him on the shoulder. Lou Yu smiled and continued: "I remember my grandfather looked at me curiously and said that this is an ordinary door in the laboratory, but It's strong and hard to break."

Tang Yu nodded, no wonder, the first time he met Lou Yu, Chu Lan told Lou Yu that his grandfather was a researcher, but he didn't know what kind of experiment his grandfather was engaged in, if it was an *experiment...

"Wait, according to what you said, here...is an underground research institute or something?" Chu Lan asked in surprise.

"That's right, this is indeed an underground research institute, and it's also a secret research institute. I guess it's a good thing that the experiments are gone." Tang Yu replied with a sneer.

"Um, established in secret?" Lou Yu asked.

Tang Yu continued: "Otherwise? This is a no-man's land deep in the mountains, and it is difficult to even transport supplies, and the lizard people we met before. If these are connected, this place is not formal at all. It is probably very Few people will know that there is a research institute here!"

"Lizardman Lizardman, lizard...people...wouldn't be what I thought?" Lou Yu had a look of disbelief.

"Hehe, Lou Yu, you are so smart, just as you think, this is a real person, do you know how he became like this..." Tang Yu said with narrowed eyes.

Both Chu Lan and Lou Yu frowned tightly. They had heard of similar things before, and Chu Lan knew it because they had traveled to many places before and knew a lot of things.As for Lou Yu, he heard about it before the end of the world, or when two researchers in his grandfather's research institute were chatting, he didn't understand it at that time, but now he finally understands.

It's just that I didn't expect that such a thing was true, and they met them. In such a research institute, if the subject of the experiment is a human being, it may be an ordinary person, but it is not ruled out that people who have awakened supernatural powers are used for the experiment. Possibility, the risk is huge, but the risk is often accompanied by benefits, high benefits.

Both of them were silent, and Tang Yu was not talking, let the two of them digest it.Tang Yu walked to the door, looked at the combination lock above, and studied the unlocking method.

After a long time, Tang Yu suddenly said, "Where are you two going to stand until when? I have unlocked the password."

Chu Lan and Lou Yu came to their senses and hurried to Tang Yu's side. Chu Lan asked, "Have you unlocked the password?"

"En." After finishing speaking, he reached out to the door lock and turned the combination lock on the door. After a few clicks, with a "click", the door lock was opened by Tang Yu.

After opening it, Tang Yu took two steps back, Chu Lan stepped forward, was the first to open the door gently.

Several people clenched the weapons in their hands, and the door opened, but there was nothing behind the door, nothing.

After walking in the door, it looks like a typical laboratory style, ultra-modern style. The research institute, which should be very busy, is now empty. Either they have all moved away, or they have all turned into zombies.

A few people walked close to the wall, and when they reached a corner, they stopped and listened carefully, and heard intermittent footsteps, accompanied by the low roar of zombies.

Chu Lan stuck her head out, and a few zombies came from around the corner. These zombies were all wearing white robes. At a glance, they were zombies transformed by the researchers in the research institute. The white robes on their bodies were a bit dirty. , but not much broken.

Chu Lan watched for a long time after turning the corner. There was a door 100 meters behind the zombie. This door was not the same as the door they entered just now, but it was a little far away, and Chu Lan couldn't see it very clearly. These are just a few zombies. Judging by the complexity of these doors, they are probably still on the periphery of the research institute and have not yet entered the core area.

"go!"

Chu Lan took the lead, walked out from behind the corner, and walked towards the zombies that had been hovering near the door.

The appearance of several people naturally attracted the attention of the zombies. The zombies in white robes roared excitedly and walked towards Chu Lan and the others. The zombies who hadn't tasted human flesh for a long time roared, Thirst, but these zombies are just the lowest level of zombies, they are not fast, and they die relatively quickly.

Chu Lan's wind blade shot out, killing the zombies in an instant.

Several people stepped over the corpses of these zombies and walked to the door. Several people studied how to open the door. Violent destruction is naturally impossible. They don't know how many zombies are behind this door. Are there any? They don't even know the living people. If they break open violently, wouldn't the movement tell the people inside and Lost that someone has come in!Come here quickly!

So it's better to do the breaking game honestly!At least it's safe, isn't it!

"This door..." Tang Yu rubbed his chin and looked at the coded lock on the door, feeling a little strange. This kind of door should not be opened with a code, but why is there a coded lock?Tang Yu stretched out his hand, just about to touch the door, but stopped when he was one centimeter away from the door.

Tang Yu just raised his hands and thought for a while, then turned around and walked towards the zombies killed by Chu Lan, squatted beside the zombies for a while, and searched the zombies all over , and then walk back satisfied.

Chu Lan and Lou Yu looked at Tang Yu suspiciously, not knowing what Tang Yu wanted to do, but judging by Tang Yu's expression, there should be a way to open the door.

Tang Yu took out a sign hanging around the zombie's neck, looked at the information on it, um...it's useless.Tang Yu shrugged, and put the sign on a display screen next to the door.

With a sound of "beep", the door slowly opened, Tang Yu nodded, it seems that the combination lock just now is a trap, if people don't look carefully, they will think that there is a place to unlock, so no matter how you change the combination lock It's all wrong, and it will trigger an alarm. Fortunately, I just took a closer look at the clothes of the zombies. The signs everyone is wearing are not decorations.

When the door was halfway open, a hand suddenly stretched out from behind the door.Some flesh and blood remained on the long nails, the arm was dry, and some places were beginning to rot.

Fortunately, several people had been prepared for a long time, and they didn't panic about the sudden loss of claws. Tang Yu stepped forward and stabbed down, and the zombie's arm fell to the ground with a thud, and the zombie behind the door roared loudly.

The door was finally opened. Tang Yu and the others walked in, and the door behind them closed automatically.Tang Yu didn't look back, he stepped forward and killed the zombie whose arm had just been chopped off.

Because the roar of the zombie just now attracted a lot of zombies, their mobility is much better than the few zombies outside just now, at least not so slow, and their clothes are also stained with a lot of blood, it seems There is no shortage of food for these zombies.
