However, except for that place, she had indeed checked all the other places, and there was nothing out of the ordinary.

Outside the door, another guard patrolled by.

Ye Jiujiu listened attentively, the guard was just passing by, and he had no intention of entering the door, so he breathed a sigh of relief and looked at Qi Yao, who was still groping: "There will probably be nothing to gain today, let's go first, so as not to arouse suspicion." ”

Qi Yao nodded, it was indeed too long for them to come out.

Ye Jiujiu walked to the door, raised his hand to press the password, this door, whether it is in or out, has a password door with a number installed, Ye Jiujiu raised his hand and pressed the first number, but suddenly paused, no, this number button is different from the one outside the door.

Ye Jiujiu clenched his hand into a fist, withdrew his hand, closed his eyes and carefully recalled the few keys that Chio Kikuchi pressed at that time.

She clearly remembers that the code for entering the door was not the same as the code for exiting.

But what exactly?

Ye Jiujiu only pressed one number, and did not continue, just as she was thinking, there was a sudden "pop" sound in the laboratory.

Ye Jiujiu suddenly opened his eyes and looked at Qi Yao: "Qi Yao, did you hear any sound just now?" ”

Qi Yao shook his head, not knowing why: "I didn't hear it." ”

Ye Jiujiu was silent for a while, she was very confident in her hearing, although the voice just now was extremely subtle, but she could be very sure that there was a very subtle "pop" sound in the laboratory just now.

It's like the sound when you just open the combination lock and enter the door.

Ye Jiujiu gritted his teeth and decided to look for another circle.

Qi Yao saw Ye Jiujiu's movements, hesitated slightly, and then reminded: "If you don't go back, it will arouse suspicion." ”

"Soon, soon, I'll see." If you don't look at it, Ye Jiujiu will definitely not be reconciled.

Ye Jiujiu said and began to grope his way through the walls inch by inch as he had just started when he first entered the door.

Seeing this, Qi Yao knew that he couldn't persuade Ye Jiujiu, so he also joined the team that touched the wall.

After about seven or eight minutes, Qi Yao suddenly spoke: "Here." ”

Ye Jiujiu turned around and walked in the direction of Qi Yao, Qi Yao pointed to the place where he touched, there was a gap.

Every inch of the wall here is complete, Qi Yao has just touched every inch of the wall here, but now, there is a gap in this small piece of wall.

The gap is very small, just like the kind of gap in the wall of the home that has been cracked due to a long period of time, not very big, at least such a gap, Qi Yao can't think of what to do.

Even if you can't do anything, it doesn't change the fact that it came later.

Ye Jiujiu raised his hand, and his fingertips slowly descended along the gap, and at the bottom of the gap, his fingertips suddenly exerted force, and the whole wall was like made of tofu, and the whole thing sank into it.

The human-high wall suddenly sank into it, making Qi Yao and Ye Jiujiu startled, there was no dust, this wall was obviously often moved, it turned out that the mechanism was on the combination lock.

Ye Jiujiu and Qi Yao walked inside, and as soon as they walked in, the human-high wall slowly and automatically went back again, still tightly sealed, and there was no trace to be seen.

"It turns out that the mechanism is really in this lab." Qi Yao was amazed, and suddenly looked at Ye Jiujiu curiously: "How did you know that the organ must be in the laboratory?" ”
