When Alina and Murong Lianxue returned to the laboratory again, the small room was dusty, and there was light in the pit on the ground, which had obviously been opened by Chu Tiancheng, and the light came from the lower floor. Murong Lianxue had already prepared, wearing a dust mask, turned on the dust sprayer on her back to spray the flying dust, and jumped into the hole first.

"That's it!"

After solving the flying dust, Murong Lianxue threw the mask and sprayer. Alina jumped down in response, ignoring the broken walls all over the floor, the second floor was much cleaner than the first, the air was not humid, there was no stagnant moss or anything on the ground, and there was no squeak of rats.

"What about others?"

Alina asked Murong Lianxue.

"I didn't see it when I came down. ”

Murong Lianxue shook her head and said.

At this time, Ji Wuying's voice came from the communicator: "Alina, Chu Tiancheng is now in Area D, if you don't hurry up and drag him down, at his current speed, in less than a minute, he can see the escalator leading to the third floor...... Don't reply to me, I've only temporarily opened the communication between the two of you, you talk, he can hear. ”

Alina glanced at Murong Lianxue, and then pressed the communicator in her ear and said, "Tiancheng, where are you?

Zone D.

Chu Tiancheng heard Alina's voice coming from the communicator, and hesitated whether to respond, at this moment, his psychology still felt that Alina was hiding something from him, and he hated this feeling. After a moment's thought, he took off the communicator, pinched it into powder, and continued his search. When he first came down, he could feel that the breath was still underground, so he thought that there must be a passage to the lower level nearby, and there was no need to open the way with his fists. Both the circuit and the light tube here are still available, and it is much easier to search.

Sure enough, soon he saw the escalator leading to the lower floor, and the other end of the escalator was connected to the upper escalator, and sure enough, there was a passage down the upper floor, but they didn't find it.

But for this reason, his suspicion of Alina is even deeper, after all, no matter how the dark organization is out of control, it will not get out of control to such a point, Alina really doesn't even know how many layers this laboratory has?

With complicated emotions, Chu Tiancheng prepared to go to the lower floor, that is, the negative third floor. At this time, Alina and Murong Lianxue chased after her: "Tiancheng, I finally found you...... Huh, there's a lower level here?"

Chu Tiancheng stopped and turned to look at Alina. Alina walked up to him with a worried face, saying something of concern and helping him clean the dust off his body.

Looking at Alina, Chu Tiancheng felt very uncomfortable, yesterday, he was still worried about Alina, he really felt that Alina was a trustworthy person, but today, Alina's actions made him very puzzled. Did you believe the wrong person, or did you think too much?

"Are you hiding something from me?"

Chu Tiancheng finally couldn't help it and asked Alina bluntly.

"Huh?"

Alina didn't seem to expect Chu Tiancheng to really ask this question, and was stunned for a moment. A trace of consternation also flashed on Murong Lianxue's face next to her, and it was fleeting, and the atmosphere suddenly became quite awkward.

"How so, what can I hide from you?"

Alina reacted quickly, barely hesitated, and said with a smile.

"Really?"

"Of course it's true!"

Chu Tiancheng looked at Alina's eyes, feeling a little confused. Some people say that by looking at the other party's eyes, you can know if the other party is lying, but he didn't see anything suspicious in Alina's eyes, but the suspicion in his heart was deeper. Without further questioning, he stepped onto the escalator first.

The third floor is about the same as the second floor, and the rooms passing by are empty and clean. Chu Tiancheng searched for that mysterious aura and came to a small room that was almost the same as the second floor, but this was still not the origin of the breath.

"Not here?"

Murong Lianxue saw Chu Tiancheng staring at the floor in the center of the room and confirmed.

"It felt closer, and the breath was a little stronger. ”

Chu Tiancheng did not answer directly.

"And the lower floors?"

Alina asked.

"I think so. ”

Chu Tiancheng's tone was very affirmative.

"So let's look and see if there's a staircase leading to the lower floor?"

Alina suggested.

"I don't think it's that much trouble!"

The two looked at Chu Tiancheng puzzled.

"I think you've got enough, right?"

Chu Tiancheng looked at Murong Lianxue with a smile.

"That's ...... Look how many layers are down there......"

The fourth, fifth, and second and third floors were all about the same, cleaned up until the sixth floor, and the rooms were about the same size as the previous ones, but the things in the rooms were still big, at least most of them.

It looked like an office, with the exception of the one with the door, each of the other three walls occupied by a large bookshelf filled with folders and information books, as well as some bone ornaments. Judging from the titles of those source books, most of them are related to biochemistry.

On the left side of the door is a desk, which is also full of folders and books, and there are many bone playthings on it. It seems that the owner of the room has a soft spot for bone products, if not one of them, then certainly one of them.

There is also a conspicuous display case next to the desk, which is simple in structure, but it is not ordinary at first glance, and this can be concluded by the fact that the lock of the display cabinet is a biochemical combination lock.

At this point, the cabinet is empty, unless the display case contains colorless gas, otherwise the contents have been taken. However, judging from the delicate little claw in the center of the display case, it should not be a colorless gas, but a thing about half the size of a fist.

After Chu Tiancheng glanced at the room, his gaze stayed on the delicate little claw in the display case. He walked straight to the display case, paused in front of it, and carefully examined the little claw.

Murong Lianxue came to Chu Tiancheng's side, looked at the small claw in the display case, and sighed lightly: "It seems that the things have been taken away." ”

Chu Tiancheng ignored Murong Lianxue, but put his hand on Zhan Wei. Murong Lianxue said it well, the thing should have been taken away, but that mysterious aura came from this display case.

When his hand touched the wall of the cabinet, he could clearly feel the mysterious aura flowing through the wall, then to his hand, and finally through his hand and into his body.

The moment that mysterious breath flowed into Chu Tiancheng's body, Chu Tiancheng actually felt a long-lost sense of comfort, he closed his eyes, raised his head slightly, as if he had walked into nature, and took a deep breath. He simply pressed his hands on the wall of the cabinet, absorbing the remaining breath on the wall of the cabinet.

Murong Lianxue, who was next to her, was a little stunned when she saw Chu Tiancheng holding it like this. He took two small steps back and looked at Alina, and although he didn't speak, the look on his face already expressed his doubts.

Alina was relatively calm, just waved her hand slightly to Murong Lianxue, signaling the other party not to act rashly. The two of them just looked at Chu Tiancheng and reveled in front of an empty display case, and the painting style was quite weird.

"Bang!"

With a muffled sound, the display case suddenly cracked open and shattered to the ground.
