Two days later, Xia Ruo had just returned from the mecha manufacturing class from Teacher Gu's side, and when he entered the door, he saw Tan Chu sitting in the living room.

"Doctor, why are you here?" She smiled and walked over and sat down.

Xia Xuan, who was entertaining Tan Chu, knew that they had something to say, so he said hello and went upstairs first.

Tan Chu was a little apologetic, "I'm sorry Doctor Xia, I have something to look for you, so I came to the door in person, and I hope I didn't disturb you." ”

Xia Ruo guessed that it might be related to the previous incident, "Haven't you found the source yet?" ”

Tan Chu said with a little helplessness: "I found it, it was the main water source on the life star that was poisoned, but the medical and detoxification experts on our side studied it, but they couldn't get rid of the poison of the water source." ”

"We've also caught a group of people peddling healing potions on Life Star, but they can only unravel the poison of a single patient, and can't solve the origin."

He looked at Xia Ruo seriously and continued: "So I have to trouble you again today!" ”

Since Xia Ruocai had only diagnosed the condition of the three people, they could determine that it was poisoning, and they had also checked that after the three people took the pills she concocted, the symptoms of the three of them disappeared in one day, which was better than the treatment potions sold by the group.

This shows that Xia Ruo may solve the problem of water sources.

"The water source they poisoned is the main water source of that life star, and half of the people need to drink it every day, if the root cause problem is not solved, more and more people will be poisoned, or the water source will be completely wasted."

Tan Chu sighed and said, "The meaning of the expert's investigation here is that if the water source can be saved, the loss can be minimized. ”

Xia Ruo nodded: "Understood!" ”

"I haven't seen the water source, so I'm not sure if I can solve it, so I need to go and see it." She didn't have a packing ticket.

Tan Chu's face was happy, "That's great!" ”

"Do you think you can do it today?" He asked, a little embarrassed.

He really has no choice, he really can't solve the problem after thinking of many ways, so he can only be cheeky to ask Xia Ruo for help, after all, this is related to the health of many people.

Since Xia Ruo wants to help, he naturally won't pretentiously delay or set his own time, "Okay, then let's go over now." ”

"I'm going to arrange for the spaceship and have them come and pick us up." Tan Chu breathed a sigh of relief and took out the terminal arrangement.

He was quick to contact there, and in about ten minutes, the spaceship was over the villa.

Xia Ruo collected some medicinal herbs grown outside the villa and put them into the space, and followed Tan Chu on the spaceship.

At this time, there was a general waiting on the spaceship, and it was still an old acquaintance, Lu Xu.

"Ruoruo, meet again!" Lu Xu smiled and stretched out his hand.

Xia Ruo stretched out his hand and shook him, "Brother Lu is good!" ”

"I'm relieved that Dr. Tan invited you here!" The solemn look on Lu Xu's original face relaxed a lot, "Please, let's arrive at that Life Star in about an hour!" ”

Xia Ruo smiled and walked with them into the hall of the spaceship and sat down.

After sitting down, Xia Ruo looked at the two of them and asked, "Have you found out who poisoned it?" In order to sell therapeutic agents? ”

Lu Xu replied: "It has been found out that the First Star Thieves Group did it behind the scenes, and their purpose is to avenge the two people we arrested in the Semi-Desolate Star before, intercepted two biological mechas, and secondly, to make money." ”

He continued: "The price of the treatment drugs they sell is not low, and so many people are poisoned, many people eat the effective ones and buy them, which is very profitable! ”

"It's not the first time they've done something like this!"
