Shi Lei was stunned to see this scene, not because of the arrogance of men, but because of the pattern on the wrist seen in the surveillance.

Shi Lei didn't know what the pattern meant before, but he seemed to have seen the picture of black dragon and white tiger intertwined in Li Qing's side, which showed that there must be organization behind the man.

The reason why men are so arrogant in front of surveillance has not been found is that no one pays attention to this side if something doesn't happen on weekdays. In addition, diseases break out a few days after men leave, so naturally no one pays attention to these.

And now after Shi Lei sees this, in the mind then begins to continue to revolve.

"Well, where on earth did he go?"

Shi Lei points to the camera where the man finally disappears and looks at Jinshan.

"This place seems to be near a piece of farmland next to the town. There are Dashan reservoir and other places over there. Who can know where he has gone?"

Reservoir?

When Shi Lei heard about the reservoir, he immediately thought of something. He asked Jinshan to take him to the reservoir. Then he went back to the gas station and saw the man who was rescued by himself.

Li Qing has tried her best to cure him. Seeing Shi Lei coming back, she immediately said with a smile: "don't worry, I've been the king of poison for decades at least. This minor illness is not so serious."

Shi Lei now also knows that this is not an infectious disease, so he said the picture he saw just now, and then said, "I guess it's not an infectious disease, it's someone who is targeting at this town and is specially poisoning this place, so this is the situation."

"I know."

Li Qing took out a big box from his room, which was basically all the herbs collected by Li Qing in recent years. For these poison kings, the proportion of using western medicine to poison was still relatively small.

"Now his condition has basically stabilized, and the toxicity is very strong, but it is much worse than my level, mainly by destroying the balance in the internal organs, which leads to the pathological changes of Qi vessels."

Just when Shi Lei was searching for news everywhere, Li Qing had almost got a clear idea of the pathology of the disease. It just took a certain amount of time to try out a new antidote.

In this case, the most urgent thing is that Shi Lei needs to find the real reason so that the rest of the people in Huashu town will not be infected.

Although Li Qing didn't say anything, Shi Lei went to the reservoir again in the next second.

After feeling the breath of the patient, what Shi Lei wants to do is to check whether the water quality in the reservoir has the same breath as the disease.

In traditional Chinese medicine, a lot of things need feeling to understand. Shi Lei thought that this side of the reservoir was the scene of the first crime, but after nearly half an hour of investigation, he still found nothing.

"Isn't it this way?"

Shi Lei began to doubt his judgment.

At this time, Jinshan came to Shi Lei's side again. Looking at the nervous Shi Lei, he carefully asked, "doctor Shi, what's the matter now?"

"I haven't found it yet. It seems that this is not the truth."

Shi Lei said as he closed his eyes and tried to recall the pictures he saw in the surveillance. For the existence of that man, Shi Lei just wanted to see where he would finally appear.

"Doctor Shi, do you mean that the reason why we get sick is because we are poisoned invisibly? Is it through water or something? "

Jinshan looked at Shi Lei and said.

"Yes, I've confirmed that it's not an infectious disease, so you don't have to worry about it, but there must be some place in your town where it still exists, so you still need to be very careful."

"Dr. Shi, since I talk about this, I have an idea, but I don't know whether it's true or not."

Jinshan said softly.

"Do you have an idea?"

Shi Lei is not familiar with the whole birch town. So far, his only clue is the surveillance video.

"In fact, the drinking water in our whole town is not this reservoir. After all, the terrain here is not very good. We all drink from the water source there."

Said, Jinshan with Shi Lei to the other side of the water plant.

"I didn't notice this before. If you hadn't been looking for it in the reservoir, I didn't think of it. It's completely opposite the town just now. Come with me."

Shi Lei followed Jinshan to the waterworks. Although Huashu town is not very big, it still has its own waterworks company. When Shi Lei arrived here, he saw a familiar figure.

"Why are you here?"

Shi Lei said in surprise.

Li Qing was standing next to the water source, with her back to Shi Lei. After hearing Shi Lei's voice, she turned around and said with a smile, "you are much slower than I thought."

Li Qing seemed to have known for a long time that something was wrong here, and slowly said, "in fact, you should have thought of it long ago. Didn't you feel this familiar breath?"

It was only at this time that Shi Lei gradually found out that in fact, the breath felt by the patient here in the waterworks was so consistent with that of the former patient.

Shi Lei slowly raised his head, looked at Li Qing and said, "you are really much more powerful than I expected."

"The power of yin and Yang is only an auxiliary function after all. You boy, for so many years, you have gone too far."

Li Qing said with a smile.

Jinshan didn't seem to know what the two people around him meant. He looked at them blankly and said, "you are..."

"Nothing. Now that the problem has been found, it's better for your town to contact the people over there at the waterworks to relocate the site, or wait until we have disposed of the poisons in the water source, and then restart the water supply. In these days, if you want to drink water, you can buy some bottled water."

Shi Lei turned to Jinshan and said, "believe me, let those people in the auditorium come out and resume their normal life. This master and I will help you."

Looking at Shi Lei's eyes, Jinshan was very moved to kneel down on the ground. From Shi Lei, he kowtowed a few heads, and then said excitedly: "don't worry, I'll let them come out and finally live a normal life. If it wasn't for you, I really can't imagine what I can do now..."

Shi Lei shook his head, helped him up and said slowly, "go back quickly. They are still waiting for you."

Jinshan gave a sound, and then immediately returned to the auditorium, while the rest of Shi Lei and Li Qing began to look very serious.

"Do you know who did it?"
