For some reason, Qin Ya was silent for the rest of the time, except for a big kill in the internal laboratory, but she seemed to have great trust in Lin Cheng, and she could even understand some of Lin Cheng's simple instructions, which was why she rushed forward so honestly.

"I really don't know what this Qin Ya is thinking in her head, so many of us have been communicating with her for five months without any gain, but I didn't expect you, a guy who hasn't been here for half a day, to take her in so inexplicably......"

Probably because he was at the forefront, Meng Yi was a little bottomless in his heart, and he didn't care about Lin Cheng's cold attitude, so he opened his mouth and complained to him again.

Hearing Meng Yi's complaint, Lin Cheng didn't plan to deal with her, but after thinking about it, this woman will still be useful to him in the future, and if the relationship is better, it will also facilitate the smooth progress of his future tasks, so he replied angrily: "Instead of complaining about this and complaining about that, why don't you reflect on what you did wrong?" Also, this girl belongs to me from now on, and you'd better stop hitting her with any ideas, understand? ”

"Why?!"

Hearing this, Meng Yi, who was walking in the front, suddenly stopped, turned back to him with an angry face and said, "Qin Ya is obviously the success of our experimental group A for nearly a month, why do you say that you want to leave?" ”

Seeing Meng Yi's angry look, Lin Cheng couldn't help but sneer, "I can easily take you out of this cage, or I can beat you into the abyss again!" ”

"You...... Hum! ”

Hearing Lin Cheng's naked threat, Meng Yi, who didn't know how to refute this barbaric theory at all, suddenly felt bored in his heart, and could only snort lightly, too lazy to talk nonsense with this unreasonable guy again, turned his head and continued to crawl forward.

After a while, with the turn of the ventilation duct in front of her, the passage that could crawl finally came to an end, seeing that there was no way ahead, Meng Yi picked up the flashlight that Lin Cheng gave her before and shone it upward, and then asked Lin Cheng helplessly: "What should I do next?" It's easy to go down this straight up and down passage, but if you want to go up......"

Before she could finish speaking, Lin Cheng directly stretched out his right hand and patted it lightly on the iron sheet on the side, and then heard a burst of frost condensation coming from the ventilation channel above Meng Yi's head!

Looking at the ice crystal handrail that appeared in front of him out of thin air, Meng Yi, who had already been a little numb to Lin Cheng's various strange methods, was only stunned for a moment, and then grabbed the handrail and slowly climbed up.

After Meng Yi climbed up a few meters, Lin Cheng stopped Qin Ya who wanted to follow, patted his shoulder and motioned for her to climb on his back, and after she honestly lay on her back, Lin Cheng took out the rope before again and tied the two firmly together, and then grabbed the handrail, followed by Meng Yi and quickly climbed up.

"Whew...... Whew......"

In the long and oppressive ventilation duct, Meng Yi's increasingly heavy wheezing sound came from above from time to time, and Lin Cheng followed behind her with Qin Ya on his back, slapping her ass hard every time Meng Yi was exhausted and wanted to stop to rest, forcing her to climb up hard.

"I finally understand why you insist on being the queen......"

Feeling that she was already numb by Lin Cheng's buttocks, Meng Yi, who was sweating profusely, looked extremely embarrassed at this time, plus Lin Cheng kept forcing her to climb up like a life-urging ghost below, and finally couldn't help muttering to Lin Cheng.

"Do you think freedom is so easy to get?"

Hearing Meng Yi's complaint, Lin Cheng slapped her ass hard again, and then replied after Meng Yi reluctantly moved up.

Hearing this, Meng Yi used his strength to eat milk and climbed a few meters more, and after feeling that his strength was running out, he asked him very tiredly: "Can ...... But can you tell me how far we are from freedom? ”

"It's not far away, and it's almost there if you work harder."

After roughly calculating the distance in his mind, he felt that he was already very close to the exit, Lin Cheng replied casually, and was thinking that if he really couldn't do it, he would directly hold Meng Yi's ass and push her up, but suddenly heard a familiar dog barking from not far above his head!

"This idiot has a keen sense of smell."

Hearing this dog barking, Lin Cheng couldn't help but chuckle, and at the same time, he finally had a chance to breathe a sigh in his heart, although he didn't encounter any great danger in this underground research institute, but compared to the battle just now where the strength of the two sides was very different, the information in Meng Yi's mouth made him feel even more shocking!

If he hadn't been lucky enough to enter this underground research institute, he might not have known that the test subjects at this stage had been studied to such a terrifying level, let alone that these so-called high-level leaders of the headquarters not only used a large number of living people to conduct human experiments, but even used people with abilities that belonged to the backbone of the last days to conduct all kinds of inhumane experiments!

Lin Cheng thought he had seen enough of human experiments, but when he arrived here, he found that what he had encountered before was completely pediatrics, and it is no exaggeration to say that the researchers of this underground research institute were about to play with human experiments under the strong pressure of the headquarters!

"Yes...... Am I hallucinating? Have you ever heard a dog barking? ”

The barking of Coke also attracted Meng Yi's attention, but she didn't know the existence of Coke, and she naturally couldn't believe it when she heard the barking of the dog at this time, after all, at this stage, even people can't eat, who has surplus food to raise dogs?

"You're not hallucinating, it's my buddy who greets us."

Hearing the cry of Coke, Lin Cheng's mood became more and more relaxed at this time, and after hearing Meng Yi's inquiry, he replied casually, and then he didn't plan to rub it here anymore, so he pushed Meng Yi's ass hard, and directly supported her to go up quickly!

"You...... You let go! I can climb on my own! ”

Feeling the touch from his buttocks, Meng Yi didn't have time to figure out what was going on with the partner in Lin Cheng's mouth at this time, and shouted to Lin Cheng with a look of shame!

"You're too slow, I don't want to continue grinding here with you, so just bear with it!"

didn't care about Meng Yi's attitude, Lin Cheng pushed Meng Yi hard, and at the same time his feet quickly kicked up on the handrail, but after a moment's effort, with a light above his head, Lin Cheng finally kicked hard, and rushed out of this ventilation pipe that made him full of harvest with Meng Yi and Qin Ya!

"Ouch, my brother Cheng, your old man can be regarded as coming out! I can't help but want to go in and find you any longer! ”

As soon as he jumped out of the vent, before Lin Cheng could stand firmly, he heard Lin Yongjian's shout full of surprise coming from below!
