Nana opened the space armor and jumped into the door that was open on the ground, and after a while, she shouted a few times to the top, indicating that the bottom was safe, so Liu Qian led the team members one by one to go down to the secret door.

It's dark down there, but the players are well prepared and bring all sorts of powerful lighting equipment to illuminate the underneath, and it's a large underground space with some very old factory equipment stacked with some very old factory equipment, and it is impossible to tell what it is used for.

After looking around, Liu Qian couldn't find any other place to go down, except for a large cement pool by the wall, which contained some black dirty water.

Liu Qian asked Nana to sniff the black water, and found that the water was not toxic, but it had accumulated for a long time, so it was stinky and black, and it was very turbid, and it was almost impossible to see inside, even if you shine it with a flashlight, you can't see anything clearly.

If there's a place to continue looking for a way to the secret lab, it's from this pool.

"Which of you will follow Nana down into the water?" Liu Qian asked the people around him.

Although he has the ability to breathe underwater, he wants to let these people know that they don't just follow him to experience, and when they encounter possible danger, they must take the responsibility of being cannon fodder.

After a while, no one answered, after all, the pool of water looked a little scary, and who knew if there would be any monsters underneath the water? And if there is really any underground waterway, you will lose your way and find no way back. Shall you not drown in the water?

"I'll go." Jiang Jinyuan saw that no one answered. His face turned a little pale and replied to Liu Qian. Liu Qian took good care of him along the way, which made him feel that it was not good to always take advantage of him.

"Okay, this time he goes down, next time it's your turn, and I'll arrange and assign it randomly when the time comes." Liu Qian said to the others, and then let Nana jump into the water, Jiang Jinyuan hesitated for a moment, then took off his coat and jumped into the dirty water with Nana.

A man and a dog soon disappeared in the muddy sewage. After about ten minutes, there was some noise on the surface of the water, and then Nana swam back to the surface, although it had an all-metal body structure, the space armor could produce some kind of special buoyancy underwater, allowing it to swim freely in the water.

Soon after Nana returned to the water, Jiang Jinyuan also swam back from it, the water temperature was very low, and after he swam back, he quickly dried his body with the towel he brought and put on the coat he had just taken off.

"Is there a problem under the water? Are there any dangers? Liu Qian asked Jiang Jinyuan.

"There is no danger underneath the water, and there is only a short section of standing water. Soon swam over, and on the opposite side was an empty house. But it is possible to go deeper and deeper. Jiang Jinyuan reported to Liu Qian what he had discovered.

Jiang Jinyuan was very happy after completing this investigation, and took the initiative to undertake a mission, but he did not encounter any danger, which can be regarded as a return to Liu Qian, and at the same time, he does not have to bear the dangers behind.

"Alright, let's all go over." Liu Qian said to everyone.

"Master Liu, how do you bring the clothes over?" A player had a hesitant expression, on such a cold day, it is the same thing whether the water is dirty or not, the water temperature is too low, and once the jacket or something gets wet, you can only take it off.

Liu Qian glanced at the player and did not answer his question, but simply took off his clothes neatly and threw them aside, and then jumped into the puddle. When other players saw this, they had no choice but to take off their clothes and jump into the puddle together, at this time, maybe there will be some benefits to follow-up, otherwise they can only wait outside, and this trip will be in vain.

Liu Qian led the way in front, and the others held their breath and swam behind, passing through a passage that was not very long underwater, and soon surfaced on the other surface. The situation here is indeed as Jiang Jinyuan said, it is an empty room, there is nothing in it, but it is connected to a passage leading to the inside.

After coming out of the water, it was very cold, everyone kept shivering, Liu Qian observed it, and assigned a team member to follow Nana to explore the passage ahead, and soon the team member walked back happily and told everyone a good news, there is a room at the end of the passage, and it is a dressing room, there are many wardrobes on the wall, and after opening, you can find a lot of standard warm clothes, and some diving suits and the like.

Since there was no danger, everyone went into the locker room in front of them, dried their bodies, and put on those standard warm clothes, so that they no longer felt so cold.

"I wonder why the entrance to this laboratory is so hidden and complicated? But it is conceivable that the more hidden and complex the entrance, the more incredible the secrets may be hidden inside. Qiu Tao sighed there after changing his clothes.

"Yes! It's so hidden, it's impossible to say that there are no secrets. Other players also echoed Qiu Tao's words.

Liu Qian didn't feel anything about this, the entrance of this laboratory was not hidden at all, it was too far behind the Qingtai Mountain Laboratory and the Undersea Laboratory, at most it could be at the same level as the Lake Island Laboratory.

However, Liu Gan's psychological expectations for this expedition are not very high, as long as he can obtain an ability, a treasure, or a chance to upgrade a level, he will be satisfied. In Liu Qian's feelings, Evil Dragon Bay should be more worth looking forward to than this laboratory.

After leaving the locker room, there was a sound of zombie wails and footsteps in the dark corridor in the distance, and it seemed that the movement of the players had attracted some zombies in the laboratory. These zombies, like the zombies outside, have undergone inexplicable black spot mutations, and they are wearing laboratory white coats and unique costumes.

Liu Qian felt more and more that the appearance of the black spot zombie this time could mean that something big had happened, if the red rain three days before the game was launched was the beginning of the catastrophe, then the large-scale appearance of the black spot zombie this time means that the game is about to enter the second catastrophe period, and maybe the whole trembling world will undergo new changes.

It's just that this kind of change, Liu Qian, who has been staying in the novice village recently, hasn't really felt it exactly, and if you take a walk outside, you will definitely feel it more profoundly.

Players are evolving, zombies are evolving, monsters are not stopping to evolve, and the competition between various species is the speed of evolution. (To be continued.) )
