Zhang Heng looked at the college student in front of him, the latter was like the inspirational protagonist in the movie who overcame many difficulties, overcame mental illness, and finally regained his life, sweeping away the previous gloomy atmosphere.

He just stood there, talking about how he got out of the trough of his life, how he was ashamed of his parents and friends during this time, and let others worry about him.

Whether it is emotions, movements, or expressions, it can be seen from the reaction of the cashier on the other side that this story of the prodigal son who turned back and did not change money is very marketable no matter when it is put on.

However, there is a process to be taken into account, and mental illness is also a type of disease, and even if a very small number of people can recover on their own, it takes time.

College students live in a simple house on weekdays, rarely leave their bedrooms, others may not know him, but as Zhang Heng, who had just met him yesterday afternoon and the night before yesterday, he knew very well that the former's "condition" did not show any signs of improvement, Zhang Heng still clearly remembered that the college student even took off his pants directly in front of him in order to pretend to be stupid.

And when the sound of the key inserting into the lock hole sounded, the horrified look on the other party's face was by no means disguised.

However, less than a day has passed, and the college student has suddenly recovered, and after a night of disappearance, he has reappeared, and it has appeared directly in everyone's field of vision unusually.

But now is not the time for the showdown, Zhang Heng then pointed to the side of the college student's head, "Where did your hair go there?" ”

"Oh, I accidentally fell and hit the coffee table before, and I had to shave my hair when I stitched up the wound." The college student explained, pulling the rest of his hair open as he spoke, and there was indeed a wound that had been stitched up.

"Yo, does it hurt," the cashier girl said distressed, "I heard that there was a thief in your house, was your injury left when you fought with the thief?" ”

"No, the thief had already run away when we woke up." The college student shook his head and said, "I fell later when I was packing my things." ”

Zhang Heng knew that the college student was lying, because the latter's hair was obviously pulled out by someone, and now it was still in Zhang Heng's schoolbag, in a fresh-keeping bag, and some blood stains and scalp tissue could even be seen at the end, and their family was not at home last night, how could there be anything after waking up.

However, what really made Zhang Heng curious was how the college student changed from the person who cowered and begged for mercy when he saw people to the person who now lied without a red face and a heartbeat, and even after experiencing a copy of the deduction method, he couldn't see any flaws.

It's like a completely different person for college students nowadays.

Thinking of this, Zhang Heng's heart moved, he picked out a cute extra from the freezer on the side, handed it to the cashier, and said to the college student, "I don't have enough change in my mobile wallet, can you help me pay it first?" ”

"No problem." The college student said happily and took out his wallet at the same time, "Everyone is a neighbor of the same yard, and I have caused you a lot of trouble before." ”

Zhang Heng raised his eyebrows and didn't say anything, he was basically sure that the college student in front of him was not just lying, but he was afraid that he had already been replaced, because the other party didn't remember that he had received a dollar from him two days ago when he bought cigarettes, otherwise when he bought ice cream and asked the other party to pay in advance, the college student would not have mentioned it.

Is this what you're going to deal with this dungeon?

It can quietly replace one person with another without attracting the attention of others, and judging from the cashier's reaction, she obviously did not realize that the college student she was familiar with had been dropped.

But in this way, some things can make sense, the college student used to show so much fear of his parents, because he found out that his parents are no longer his parents, and it has nothing to do with the so-called emotional entanglement, which is probably the real reason why he suffers from mental illness.

It's just that no one believes him, after all, if he hadn't seen it with his own eyes, Zhang Heng would have found it hard to believe that such a bizarre thing would happen.

Zhang Heng couldn't even imagine how the college student lived with his fake parents after being released from the mental hospital, and it was a miracle that he didn't really go crazy under such psychological pressure.

But now it seems that his good fortune has ended there.

Just last night, what happened to his parents finally happened to him.

However, Zhang Heng did not attack immediately.

Because now he is also facing the problems that college students have faced, all of the above is just his speculation, he can't prove to others that college students are no longer college students, because in appearance, there is no difference between the two, Zhang Heng doesn't even know what the alien enemies he is facing are, what means they used to replace college students, is it similar to replication and cloning technology, or parasitic like aliens, or some kind of mind control?

And he has to take into account the aftermath of the attack, because although the duration of this copy is much shorter than before, it is also 140 days, which is not the vast West of the United States in the 19th century, and it is difficult to be found after killing a family.

Zhang Heng didn't know how many people there were, and who else was controlled besides the college student's family, so it was not the best choice for him to tear his face directly at this stage, it was wisest to keep a low profile, continue to collect evidence, and investigate.

Of course, Zhang Heng was also vigilant in his heart, although judging from the performance of the fake college student, he didn't seem to know what happened before, but Zhang Heng couldn't be completely sure that in order to survive, the college student would tell his fake parents about the things he had visited.

In the worst-case scenario, he is likely to have already been exposed, so he also needs to be prepared for both.

Zhang Heng took his sorbet from the cashier's hand, thanked the college student, and then turned around and left the convenience store with his schoolbag.

Although Zhang Heng didn't look back, he was sure that the fake college student had been watching him from behind.

This feeling is very bad, and more importantly, after discovering that the college student was quietly dropped, Zhang Heng suddenly realized that in this copy, he may have to rely on himself, because he doesn't know who else can be trusted.

It's been a long time since he's been in a situation where he doesn't know who the enemy is, where he's coming from, and how many there are.

Dangerous, not scary. Ignorance and suspicion are terrible.

Zhang Heng opened the door and looked at his grandfather who was practicing calligraphy at the table, and suddenly felt that the other party looked a little strange.
