For the next three days, Zhang Heng and Bai Qing alternately monitored the situation in the funeral home, during which Zhang Heng slipped into the cold room again and took a CT re-taken to confirm that the thing in the fourth ventricle was still there.

Its companion didn't seem to be in a hurry to bring it back, making Zhang Heng even wonder if the thing had been hung up, after all, it hadn't changed its position from the CT scan.

In addition, he is almost a frequent visitor to the teacher's office now, and his grandfather rarely cares about his affairs, but when he went home yesterday afternoon, he had to remind him, so Bai Qing asked Zhang Heng to give her the homework, and the next morning, when the two handed over, Bai Qing brought breakfast and homework together.

And this girl is very careful, and she deliberately imitated Zhang Heng's handwriting, and finally let someone pass the test smoothly today, and even the teacher specially opened her mouth to praise two sentences.

Sure enough, everything depends on comparison, Zhang Heng has always handed in his homework on time and has not been praised before, but he didn't write his homework for three days, and then returned to normal, which made the teacher feel flattered.

However, there was no movement on the other side for so long, and Zhang Heng also began to think about whether there was something wrong with his plan.

After all, he tried to avoid the risks as much as possible, but if most of the human society has been replaced by that thing, it seems that now in the classroom, there are more than ten or twenty pairs of eyes that belong to those things, then no matter how careful he is, it is useless, but fortunately, this possibility is very small, otherwise there is no need to be so cautious about those things, and he can directly do it to him.

In addition, Zhang Heng did not give up on the side of the three children who fell into the water. Before, he learned from the mouth of the community security guard that the three children often left the community together, and Zhang Heng wanted to know where they would go.

He was hiding his phone under his desk, flipping through a map of the neighborhood when he suddenly received a message.

It was sent by Bai Qing, and there were only four words on it.

- They've arrived

Zhang Heng could feel the nervousness and apprehension in Bai Qing's heart on the other side of the phone, and he quickly replied.

- Pack the tracker and wait for me.

After that, Zhang Heng turned his head and looked at the clock hanging behind him, now the physics class is only halfway through, and there are still twenty minutes before the end of class, Zhang Heng can't wait so long, so he has to be sorry for the physics teacher on the stage.

Taking advantage of the inattention of his nearby classmates, he pressed the base of his tongue with a pencil, and then decisively began to vomit, vomiting everywhere on the table and floor, and at the same time, the green tendons on his neck burst out, looking very sad.

The physics teacher was shocked when he saw this, and hurriedly walked down from the podium, and said with concern, "What's wrong with you?" ”

"I don't know, I've been uncomfortable drinking a bag of expired yogurt in the morning." Zhang Heng's forehead was covered with sweat.

"Ah, it can't be acute enteritis." The physics teacher said with a solemn expression, "You have to go to the hospital quickly, you wait and I'll see which teacher doesn't have a class." ”

"No need Teacher Zheng, I'll just go over there."

"How can a person like you be reassured." Teacher Zheng shook his head.

"I know a friend who works in the third hospital of the city, and she will take care of me when I get to the hospital, but I am just a little weak, and I still have the strength to take a taxi." Zhang Heng said, "Our head teacher will trouble you to tell me, and I will make up for the leave note later." ”

"Okay, you can go to the hospital quickly." Teacher Zheng said.

Hearing this, Zhang Heng returned to his seat and took his schoolbag, and left the classroom smoothly.

As for the things he spit out, naturally they were cleaned up by nearby classmates, which was also a hidden benefit of the sick number.

Zhang Heng left school and first called a friend in the hospital and asked her to issue a sick note on her behalf.

The latter was a little helpless when he heard this, "Are you going to do something bad again?" Don't keep talking about me, and you haven't told me where the CT scan came from last time. ”

"Help me cover first, and the head teacher should call my grandfather later, you tell him that I am with you, it's no big deal, and I'll go back by myself after the drip, and I'll tell you when the CT problem is over." Zhang Hengdao.

"Okay, let's not take this as an example." The other end of the phone sighed, paused and added, "It looks a bit like a parasite from the film, but I later checked the relevant literature and didn't find the right number of boarding worms, as well as the shape of the fourth ventricle, which is too strange." ”

"Take my word to heart and don't tell anyone about it." Zhang Heng admonished.

After dealing with the matter of asking for leave, he could finally turn his attention back to Bai Qing and send a message to the other side.

- How's going on over there?

As a result, this time Bai Qing did not reply for a long time.

Although the situation was urgent, for the sake of prudence, Zhang Heng still went around the nearby shopping mall, shook off the tail that might follow, simply changed his clothes, and then came out to take a taxi to the funeral home.

In the car, he finally received a message from Bai Qing.

- It is finished.

After that, Zhang Heng's mobile phone really received the trajectory of the car, which was sent by the on-board tracker, and it can be seen from the above that the other party's vehicle is heading towards the east of the city, which is also consistent with Zhang Heng's previous investigation results, he tracked the red fit of the college student's home, and the last place he found was also in the east of the city.

In addition to this, there is another signal, which is emitted by a miniature tracker, which is the same as the trajectory of the car.

It seems that this time Pak Qing not only completed the task, but also exceeded it.

- Wait for me where you are.

Zhang Heng replied.

However, there is still a lot of distance between the school and the funeral home, and it was already forty minutes later when Zhang Heng arrived at the van, and the car on the map was not far from the previous parking lot. Bai Qing was obviously also in a hurry, and sent him several WeChat messages during the period, asking him where he was.

Zhang Heng replied for the last time

- It's already here.

Bai Qing, who received the news, immediately opened the car door, poked his head out, and the two exchanged codes, Zhang Heng sat in the driver's seat, while Bai Qing sat in the passenger seat, and said while wearing a seat belt, "I don't know how they did it, so that there was a little fault on the side of the freezer, they disguised themselves as maintenance personnel to deal with it, and opened the cabinet by the way." ”

"Do you see how they take the contents of their heads?"

"Nope." Bai Qing shook his head, "They were standing right in the way of blocking the camera, but I recorded their looks." As she spoke, she also sent the cut video to Zhang Heng.

Zhang Heng took a look and found that there was a fat man and a thin man in the picture, both of them were just ordinary people in terms of appearance, and a person's legs seemed to be a little wrong, and he was a little lame when he walked.

"How did you put the tracker on them?" Zhang Heng asked.

"I played to my strengths as a woman."

"Huh?"

"What are you thinking, I mean I can ask men for help, it's hard for men to say no in general." "I asked them to carry two wreaths for me, and then I gave them a small jar of fruit candy as a token of appreciation, with the tracker at the bottom of the candy box. ”
