Lu Yichen notified his father Lu Xinyi and elder brother Lu Yixuan to go back home together to discuss the next response method.

After the expert group arrived at the location, they all put on masks and rubber gloves just in case before entering the village where the outbreak occurred.

Samples were collected from various places and urgently sent to the nearest laboratory for testing. Experts were divided into two teams, each going to the patient's home to understand and examine the condition.

Most patients suffered from dry and sore throats, nausea, vomiting, and diarrhea. Some of the more serious cases started with blistering on their bodies, which then ruptured and festered. In the most serious cases, the festering areas had begun to fester. After discussion by the expert group, the possibility of infectious diseases was ruled out, which made everyone feel relieved.

The expert group was gathering together to discuss the cause of the disease. Someone came over to bring some boiled water. Because Luo Qiao had a sensitive sense of smell, she smelled a slight medicinal smell in the water and intuitively felt that there was something wrong with the water.

He quickly shouted, "Don't drink it yet, there's something wrong with this water."

Everyone was startled and quickly put down the water in their hands.

Professor Guo, who was familiar with Luo Qiao, asked, "Luo Qiao, tell me, what did you find?"

Luo Qiao raised her head and looked at Professor Guo: "Previously, the local staff said that they had tested the water source and there was no problem, but I am sure that this water has a problem. There is a faint smell of medicine in it."

Professor Guo quickly asked the comrade who was delivering water: "Which well did you get this water from?"

Everyone stood up and followed to the well, drew some water from the well, and then took a portion of the boiled water and arranged for someone to send it for testing quickly.

Luo Qiao asked someone to bring an extra portion of the well water that had just been drawn up, and told the person who sent it for testing to ask the laboratory to boil one portion of the well water before testing it again.

Professor Guo looked at Luo Qiao and asked, "You think the water itself is fine, but boiling it before drinking it is problematic?"

Luo Qiao shook her head, then nodded: "I think it's possible that the villagers' illness originated from this well. The boiled water has a faint smell of realgar, but I don't know if it's the real cause."

Professor Guo asked people to draw water from other wells in the village, put labels on them, and sent people to deliver them to the laboratory, which gave the results overnight.

After investigation, we found out that several large snakes were found here some time ago. The villagers were afraid of scaring the children, so they used a lot of realgar. They also lit a fire by the well, trying to smoke out the snakes in the cracks of the rocks.

Realgar is also poisonous. When exposed to heat, it can be oxidized into the highly toxic ingredient arsenic trioxide, also known as arsenic. Poisoning can cause dry and sore mouth and throat, nausea, vomiting, and diarrhea. In severe cases, people can die from heart failure or respiratory failure. Long-term contact can also cause skin allergies, and the appearance of papules and herpes.

The problem has been found, and the next step is treatment. However, there is no need for the expert group to stay here all the time. The doctors from the local hospital have come to take over. Since the cause has been found and infectious diseases have been ruled out, the people around are not as panicked as before.

After handing over everything the next afternoon, they prepared to evacuate. When they came here, it was because of the emergency situation, so they mobilized military aircraft, but there was no special plane to go back.

We arranged to take a bus to the city first, and then take a train back to Beijing. Luo Qiao got on the bus with her things. Professor Guo and several professors who knew Luo Qiao began to tease her, "You have prepared so many things. Are you planning to fight a protracted war?"

Luo Qiao cheated by using her bag to take out a lot of dried fruits and snacks for everyone: "My family was worried about me, so they packed a lot of food for me, but in the end, they didn't use it. If you don't mind, come and try some."

Everyone laughed: "No problem, no problem."

Luo Qiao distributed some to everyone one by one.

After eating the dried fruit, Professor Guo said: "This tastes really good. Not only you young people, but also an old man likes it."

Someone agreed: "It's delicious, it's really delicious. I was afraid of motion sickness just now, but after eating this, I feel much better now."

There is no wrong version in the 1619 book forum!

The road here is really unfriendly. It is so bumpy that it feels like riding a horse on the grassland. Just as everyone was talking about what happened, the car stopped.

Today's update is over, I wish you all a happy Dragon Boat Festival in advance! Two more chapters will be updated tomorrow, thank you for your support!
