Instructor, can I tag you?

As a person who "shows weakness in front of Qin, he will die", Chen Yu immediately suppressed the pain in his whole body when he heard this question, just raised his eyelids to look at him, and said lightly: "I'm fine."

Qin Ran replied with a sneer and asked Tang Shen with a calm face, "Hey, what's wrong with him?"

Tang Shen was taken aback by his cannibalistic tone, and replied hesitantly, "Well...Major Chen's rejection is honestly a bit special, it doesn't seem like a matter of physiological incompatibility, It seems that his mental power felt some threat from the outside world, so he couldn't help but get restless, and wanted to drag him into a closed state of mental power, I guess..."

Having said that, he stopped the pen in his hand, thoughtfully: "Major Chen, have you ever overdrawn your mental power to save someone else?"

Qin Ran's hand on Chen Yu's shoulder suddenly strengthened, and his eyes narrowed dangerously: "Who did you save?"

Chen Yu was a little uncomfortable being restrained by Qin Ran, and it was hard to struggle, so he could only calmly nod: "Yes."

Tang Shen's eyes lit up, and he suddenly realized: "Hey, I said it! That's right! I know where this stimulant sample came from!"

Chen Yu frowned: "Where?"

Tang Shen touched his chin and explained: "Hey, it was taken from the blood sample of the man you saved! I guess the guy you saved must be a sentinel, so it all makes sense! Guide If you want to use your own mental power to help a sentinel in danger, you must have a high degree of match between the pheromones of the two parties. The lower the degree of match, the lower the chance of successful treatment, and the greater the sacrifice the guide has to make."

The more he talked, the more excited he became, and he even stood up and paced back and forth with the recording paper: "Especially, if this guide has been marked by a sentinel with a higher matching degree before, it will be even worse. The sentinel marked Exclusiveness will make the guide suffer from great resistance from his own mental power when heals other sentries! This is called the matching degree priority principle."

"Of course, if the guide insists on forcibly rescuing other sentries in violation of the principle of matching priority, it will definitely cause great harm to his body and mental strength. Moreover, in the future, if he encounters the pheromone or When it's mental power or something, the guide will still have a severe stress reaction, just like Major Chen. Therefore, this stimulant sample must have come from the sentinel you once rescued, there is no other explanation!"

After finishing speaking, he stretched his waist with great satisfaction, and turned his head to look at Chen Yu and Qin Ran with great pleasure: "Great, my task is finally completed! You guys came here early in the morning, and you will be here later." I still need to catch up on sleep! Now, you two, hurry up and come out with me, I've told you the answer, and I'll take care of the rest."

Chen Yu thanked him, got up and wanted to follow Tang Shen out.

Unexpectedly, Qin Ran reached out and grabbed his wrist directly, and asked in a hoarse voice, "Who is it?"

Chen Yu glanced at him, didn't speak, just stood in a stalemate with him.

Tang Shen turned the doorknob of the laboratory with a "slap", and three heads popped out immediately, furtively looking at this side with great excitement: "Brother Chen, what's the matter, is there any result?"

Chen Yu raised his chin, motioning for Qin Ran to let go.But Qin Ran was not willing to give in at all, he just stared at him, and his hands became tighter and tighter.

Chen Yu and him looked at each other for a few seconds, and finally lost the battle. While feeling angry, he replied patiently, "Gu Heng."

Qin Ran snorted coldly, then raised the corner of his mouth and showed a very unfeeling smile: "It really is him."

Xia Man and the others were at a loss, and they gathered at the door to watch the excitement without bothering to meddle in it: "What, what is it?"

Qin Ran ignored them, just sat on the back of the chair and raised his voice and asked: "...Professor Tang, how to eliminate this stress reaction?"

Tang Shen thought about it for a while: "It's very simple, as long as you perform tagging behaviors with a higher matching sentinel for a long time, such as kissing, doing pornographic exercises on the bed, it's fine! Of course, if you just want to relieve it temporarily, If you are not in a hurry to eradicate it, just simple physical contact is fine."

As soon as the voice fell, there was a loud "bang" in the room.

Qin Ran slammed the door very violently, grabbed Chen Yu's wrist, and led him to press heavily on the door panel.

Through a small door that wasn't too thick, Chen Yu heard Tang Shen curse: "Hey, what's going on with the young people nowadays, my ass is about to be smashed."

Yiwen's tone was complicated and excited: "In broad daylight, is Brother Chen so fierce?"

Xia Man: "???"

Qin Ran lowered his head and leaned closer, the tip of his nose lightly brushed against his cheeks, and his two hot lips were almost close to his.

Chen Yu was pinned down by him, so he asked coldly, "Qin Ran, what do you want to do?"

Qin Ran gave a low laugh and said, "Why, instructor, it doesn't matter if you lost your mental body by excessively using your mental power to save Gu Heng, but now you're out of breath after being pressed by me?"

Chen Yu laughed back angrily, and his voice sounded like he was gnashing his teeth: "My spirit is very good now, so you don't need to worry about it."

As soon as the words fell, Qin Ran's hand on his side stretched up along his waistline, and the overwhelming pheromones fell towards Chen Yu all at once.

Qin Ran's tone was also very cold: "...Nonsense, I can't feel it when I'm so close to you now, do you know how fucking dangerous it is without a spiritual body?"

The pheromone of the high-matching sentinel is absolutely oppressive to the guide. Rao Chen Yu couldn't help but soften a bit at this time. He could only pant and lean against the door panel, patiently talking to him Discussed carefully: "Qin Ran, can you let me go first, I can't do anything like you..."

Chen Yu couldn't help hissing, it turned out that Qin Ran had the audacity to lower his head and bite him on the neck before he finished speaking.

This position is too sensitive, he couldn't help stretching out his hand to support Qin Ran's forearm, because only in this way can he stand firmly.

The key is that after Qin Ran finished biting, he didn't know how to restrain himself at all. Chen Yu could feel his lips moving along his neckline, neither high nor low, as if they were going to slide up in the next second.

The people from the mercenary group behind the door seemed to be really in a hurry when they saw that they hadn't come out for so long.Elsa kicked the door with her high-top boots, and said loudly: "Qin, come out, and my sister will tell you clearly, what happened to Gu Heng has nothing to do with Chen Yu's fucking!

Yiwen: "See no evil, hear no evil, and speak no evil."

Xia Man: "???"

Chen Yu was made into two big heads by these people, upset and irritable, and was about to kill Qin Ran who was still standing on his shoulder and misbehaving, when Qin Ran's movements suddenly stopped.

Chen Yu's hand touching the gun paused.

Qin Ran buried his head deeply on Chen Yu's shoulder, and the hand that was holding Chen Yu's waist also slipped down, lightly touching Chen Yu's hand twice as if a little flattering.

Then his voice muffled from Chen Yu's ear: "...I'm sorry."

Chen Yu lowered his eyes and sneered: "It's hard for you to know I'm sorry."

Qin Ran was silent for a while, and asked, "...do you still feel pain?"

Chen Yu was stunned for a moment before realizing that what he was talking about was a stress response. In an instant, an indescribable feeling surged in his heart, and he swallowed back the sarcasm and sarcasm that came to his lips, and only replied lightly. :"never mind."

Although what Qin Ran, the bastard, did just now was very unreasonable and unreasonable, but his pheromones are still useful.

After finishing speaking, he pushed Qin Ran: "Get up."

Qin Ran gave a lazily "hmm" and raised his head from Chen Yu's shoulder.

At that moment, Chen Yu saw that almost all of his eyes were dyed black, the entire pupil was as dark and deep as an ancient well, and he couldn't see to the bottom at a glance.

In particular, Xiaolong poked his head out from behind him at some point, and black air lingered on the two originally crystal dragon horns.

This scene was so familiar that it awakened a memory somewhere in Chen Yu's heart.

He frowned and said hesitantly, "You just..."

Qin Ran blinked his eyes and blocked his words: "I wanted to kiss you just now, but I didn't make it. I will try harder next time."

At this time, Chen Yu looked at him again, only to find that the blackness in his eyes just now had completely disappeared, and even the tone of his speech had returned to normal, just like Qin Ran who was full of hostility just now. Never existed.

Illusion?Chen Yu thought.

While thinking a little irritably, he held the doorknob before Qin Ran, and wanted to open the door and go out quickly, but at this moment, an inexplicable impulse surged up in his heart, which made him unable to help but speak to Qin Ran: "Actually... for the incident with Gu Heng two years ago, I didn't have to do anything to save him...but he was kind to me, and I couldn't ignore the dangerous situation on the Blue Alpha Planet at that time. "

He paused, and continued: "You may not know that Gu Heng's physique is a bit special, and he can withstand the mental strength of many guides at the same time, so after I rescued him, I helped him regain weight with Yiwen and a few students. Shaping the spiritual world. But... my best bracelet and mental power are too repelling to foreign sentries, almost not long after the treatment started, and I still don't know what is going on with my own rejection reaction , Xiaobai is already asleep..."

Qin Ran, who was following behind him, narrowed his eyes, raised his eyebrows and asked playfully, "I said, instructor, are you explaining to me?"

Chen Yu took a step forward on his own, not intending to answer.

Qin Ran stood there for a while, then suddenly bent his eyes and laughed softly: "Instructor, do you know the relationship between two people that needs to be explained under normal circumstances? If you don't know, then I can tell you quietly... "

He didn't say anything, and the screams of Yiwen rang: "Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!
