The expressions of the others were also a little solemn, but fortunately, Zhao Xian saw the clue in advance, otherwise the consequences would be really unimaginable.

"Cher, can you tell what kind of medicine is adulterated in it?" Liu Keying couldn't help but ask.

But the answer is simple.

"I studied chemistry, I am not a fortune teller, even with the most sophisticated experimental conditions and instruments, I can at most measure other components of adulteration."

Su Xue's words are very clear, according to the current experimental conditions, it is not easy to detect that there is a problem with this water.

The others did not speak, and even Li Fei fell into a short period of contemplation.

"Since you have been passive with your hands and feet, it means that this time you have been poisoned is similar to the last time, and the raw materials must be produced on the island!"

In the end, it was Zhao Xian who took the lead in analyzing and broke the silence on the field.

As soon as Zhao Xian's words came out, Li Fei was instantly awakened.

"Zhang Ting, you ask Ta Zhu, will this island or the surrounding islands produce highly poisonous flowers or plants?"

Zhang Ting nodded, and then translated Li Fei's words to Ta Zhuo.

The latter thought for a moment, then replied.

"Ta Ji said that the environment here is not very bad, so they rarely produce poisonous plants, and the last time I encountered it, it was already one of the most poisonous plants!"

Li Fei nodded, no one could have understood the level of understanding of this small island.

And it is obvious that Zhang Laosan is actually a little knowledgeable about the plants on the island, and even chemistry.

The powder that suddenly spilled last time had already caused them a lot of trouble, and this time they secretly drugged their drinking water?

After listening to Tazhuo's answer, Li Fei probably had an idea in his heart.

"Are there any hallucinogenic plants on this island?" He then continued to ask.

Zhang Ting told the truth, and Ta Zhu frowned silently.

After a long time, he suddenly seemed to remember something, and he opened his mouth with his hands dancing.

"He said that there is indeed a plant that is similar to a medical painkiller that makes people very high, which reduces the feeling of pain."

"But the side effects are very obvious, that is, after taking it, you will feel weak, even faint, and muscle aches after half an hour, and you will have to wait at least five hours to fully recover your basic ability."

Li Fei thought about it for a while, and probably had some thoughts in his heart.

"Captain, why do you do so much research, since you have found that the water is wrong, let's just not drink it." It was obvious that the girls had not yet realized Li Fei's intentions.

But the latter just shook his head slightly.

"Although we have a lot of fresh water resources, but this time he can poison it, and next time it can be the same, now the enemy is dark and I am clear, if he intends to cause harm, we have no choice."

Passive beating has never been Li Fei's style.

"What then? If he tries to dodge, it's hard for us to catch him." Lena couldn't help but speak.

These days, it's not just Li Fei, almost everyone has seen the cunning of Zhang Laosan's guy.

Except for the first day when his traces were discovered, Zhang Laosan barely showed his trace for many days, but the interesting thing is that he avoided the traps they laid well.

It wasn't the most terrifying thing, and they were surprised that this guy was able to find the location of their cistern with such precision to drop the poison.
