"What the hell is going on?" Jiutian was awe-struck in his heart. But when he was about to look more closely, he found that the green threads had disappeared again.

He suddenly felt that he had a delusion just now, but the next moment, he knew that he didn't know his mistake.

"Ding! Congratulations to the host for triggering the series of quests [Missing Students]. ”

"Task 2: Find the cause of everyone's poisoning and cure it. ”

"Current progress: 0/326.

"Reward: Intermediate Architecture Recipe Fragment*1. ”

Nine days was stunned, and there were also fragments in the formula of the middle structure? No! Everyone who was paralyzed was poisoned? Now he couldn't relax at all in the next nine days, and he knew that he had really encountered a big deal this time, and the poisoning of more than 300 people was simply a big disaster.

He was sure that the green silk thread he had just seen from the student's neck was a sign of poisoning. Since the students were poisoned, he didn't dare to be careless, so he hurriedly picked it up and put it away, turned on the camera, and aimed it at his neck.

Zheng Weiqi, who was standing behind Jiutian, suddenly raised his hand and made a V.

Nine Days: "............"

In the camera, Jiutian didn't notice anything unusual on his neck, and after feeling his body carefully, he didn't feel anything wrong. He guessed that not all of them should have been poisoned, after all, the entire Tongyuan planting base plus the staff or something, it is estimated that there are seven or eight hundred people, and the number of poisoned people is only about one-third.

However, just in case, he still asked Zheng Weiqi if he felt anything wrong with his body.

"Is something wrong?" Zheng Weiqi shook his head, but quickly realized that Jiutian would not casually ask such a thing.

"Not sure. Jiutian originally wanted to say it, but he glanced at the fierce students, and if it was poisoned, it would be too unreliable. And he has no evidence of that now. After all, the poisoning of more than 300 people is too sensational, and it is not something that anyone will believe if you tell the truth. And those green threads he had seen before were now completely gone. It's like it never existed.

But he knew he had to figure it out as soon as possible, and he didn't know when the toxins would burst out.

However, the current priority is to find out what this toxin is, and he has a bold guess, since the system task has been triggered, it means that this toxin must be related to the spirit plant. Having been with the system for so long, he probably knows the rules of the system's release tasks. If it is a chemical toxin, it will definitely not be able to trigger the task of the system.

Earlier, Lan Yuanju and the others were still discussing this matter with great interest. Jiutian's heart moved, he remembered that when he was doing the research yesterday, there was no similar green silk thread on Lan Yuanju's neck. In the afternoon, Wen Zixin and Dong Yongyuan were in Qi Taihe's research project, and there was no such situation.

Does that mean that these toxins appeared, at least last night or this morning?

The more Jiutian thought about it, the more he felt that this was very likely.

"Have you been somewhere together for the past two days?" he asked a few of his students.

Just after being reprimanded by Jiutian, the students looked like they were wandering out of the world, and they came back to their senses when they heard Jiutian's questioning.

Wen Zi said listlessly: "We didn't go anywhere...... By the way, we heard in the morning that a student was missing, so we made an appointment to look for it at the end of the morning course, and we heard that someone saw the student go northwest last night, and we went around in that direction, but we didn't find anything, and then we came back. ”

"Is that all, where did you go with you yesterday afternoon?" asked Jiutian again.

"The others don't know, I was in the hotel yesterday afternoon anyway. Wen Zi said in his heart.

"I went out on a trip, but just walked around the front of the hotel. ”

"I'm in the house too. ”

Several students gossiped.

However, Jiutian's questioning still made the students seem to notice something unusual, and they began to ask what happened to Jiutian.

He felt that if he told the truth and scared the group of teenagers to death, he would find a random street corner and perfunctory it. Of course, it's not that he doesn't care about this group of students, it's just that it seems that the toxin hasn't flare up yet, and there should be plenty of time left for him.

After asking, Jiutian immediately made a decision, took Zheng Weiqi out of the hotel, and walked in the northwest direction.

However, the planting base is very large, and the northwest direction is only a general direction, whether or not he can find some clues, Jiutian himself has no bottom in his heart.

And he found that things were far from being as simple as he thought, and there were more than 300 people poisoned, which means that this mission may be quite dangerous.

"Lao Zheng, you always pay attention to the changes in the surrounding environment, and remind me in time if there is any problem. Jiutian's expression was slightly nervous.

"Good boss. When Zheng Weiqi heard this, his face suddenly became serious, his originally slightly lazy temperament disappeared in an instant, and the whole person was like a sword out of the sheath, with sharp and sensitive eyes scanning the surroundings.

In fact, Jiutian has been unable to understand one thing, how the missing student disappeared. Along the way, he found a lot of surveillance cameras, although it can't be said that there are no dead ends, but an ordinary student, and don't know about this planting base, want to avoid these surveillance cameras is simply a fantasy.

He asked Zheng Weiqi about his doubts.

"Even if you are flying in the sky, it is impossible for the surveillance camera not to see it, unless the student can escape. Zheng Weiqi shook his head, and suddenly showed a cruel smile and said: "I prefer that this student was killed and buried immediately after leaving the hotel, this is a plantation, it is too easy to bury someone." ”

Jiutian also sighed, he actually felt that this student was likely to be more than lucky, from the time he discovered the spread of the toxin, he had already understood that this task was not the same as the previous one.

Missing students, poisoning. These two things are combined, and no matter how you look at it, it is also the beginning of a disaster movie. This made Jiutian feel inexplicably depressed.

The two of them walked northwest along the main road of the planting base, and there were wide planting fields one after another.

After walking for about an hour, Jiutian looked around, the hotel had almost disappeared from sight, at this moment they had penetrated deep into the belly area of the planting base, the surroundings were quiet, only the sound of the wind blowing the leaves, and Jiutian found that there was not even a single bird nearby, let alone people.

After a few more walks, a sweet floral scent filled the air.
