Jiang Linchuan picked up the heavy medicine box and started walking out.

The elderly doctor followed closely behind, but he was old and had difficulty walking. He was out of breath after only a few steps, and cold sweat beaded on his forehead. "I can't go on, young man, wait for me..."

Jiang Linchuan saw this and became even more anxious. He immediately stopped and said, "Dr. Wang, there's no time! I'll carry you on my back!"

Before the old doctor could react, Jiang Linchuan squatted down, handed him the medicine box, and told him to hold it tightly. Then he carried him on his back and strode towards the forest farm.

The old doctor clung to his back, bouncing back and forth, as if afraid he might fall off at any moment. "Run slowly, don't fall, safety first..."

Jiang Linchuan didn't say anything, but silently increased his speed.

The beam of the flashlight swayed in front of me.

Finally, the outline of the female educated youth dormitory came into view.

Jiang Linchuan saw Xu Xinghe pacing anxiously back and forth at the door from afar. "Li Juan, the doctor is here!"

Upon hearing the voice, Xu Xinghe immediately came to greet her.

Jiang Linchuan put the old doctor down. He was a little out of breath because he had walked too fast and was carrying someone on his back. "How are the female educated youth?"

"The situation hasn't worsened, but he still lacks strength and his consciousness isn't very clear," Xu Xinghe said as she led the old doctor back to the dormitory.

Lin Hong had already dressed the female educated youth in long-sleeved clothes and trousers, and put away anything in the room that was not suitable for outsiders to see.

The old doctor walked into the dormitory, reached out and felt the pulse of a female educated youth, then opened her eyelids to look at her, and even smelled the vomit remaining at the corner of her mouth. His expression gradually became serious.

He stood up. "It's poisoning. The symptoms... are a bit like ingesting rat poison."

"Rat poison?" Lin Hong panicked immediately upon hearing this. "Impossible! There's no rat poison in our dorm. We ate food from the cafeteria today and didn't touch anything else!"

The old doctor frowned. "Think carefully again. Besides the food in the cafeteria, what else did you eat or drink today? Has anyone come into contact with anything unusual? Some people wrap rat poison in vegetable balls to kill rats. Did you accidentally eat something?"

"No, absolutely not! We wouldn't dare touch anything outside the cafeteria!"

“No…” Xu Xinghe suddenly realized something and turned to look at Lin Hong. “Lin Hong, why are they all poisoned but you’re fine? There must be something different about you than them. Think carefully about what you ate and drank today. Was there anything different?”

Lin Hong paused for a moment, then lowered her head and began to think carefully.

After a while, her eyes suddenly lit up, and she quickly said, "That's right! Water! When I got back, I drank the boiled water I made this morning and let it cool. The three of them thought it was too much trouble and just drank the tap water from the water tank! I even tried to persuade them, saying that tap water isn't clean, but they said it was hot and drinking cold water was more comfortable..."

"Water tank!" Xu Xinghe's heart tightened, and she immediately walked towards the water tank in the corner of the dormitory.

She first leaned closer to smell it, but there wasn't a very noticeable smell. Then she scooped up a ladle of water and handed it to the old doctor. "Dr. Wang, can you smell this water? Is there anything wrong with it?"

The old doctor took the water ladle, lowered his head and sniffed it carefully. His expression changed instantly. "That's right! There's a faint smell of rat poison in this water. It's very faint, but it's definitely there. Someone must have put rat poison in the water tank!"

"What?" Lin Hong and Zhao Xiaoyan were both stunned. They never imagined that the water tank they usually used for drinking and cooking had been poisoned.

"This is not the time to be surprised!" The old doctor immediately came to his senses and ordered everyone, "Quick! Get some soapy water! Have them drink it to induce vomiting, to expel the poison from their stomachs and reduce the toxicity! I'll give them acupuncture to stabilize their condition first!"

Xu Xinghe realized what was happening and said, "Xiaoyan, the water here is no longer usable. Let's use the water from our place. Come on, let's go together. Lin Hong, you help look after them. When the soapy water arrives, we'll feed them together!"

The two hurried back to their dormitory.

Zhao Xiaoyan went straight to the water vat in the corner and reached for the ladle. "Li Juan, I'll scoop the water first. You find the soap. Let's get it ready quickly and take it over!"

"Wait!" Xu Xinghe suddenly grabbed her wrist, his voice trembling slightly.

The scene from just now was still vivid in her mind when a terrible thought suddenly popped into her head.

If someone was able to poison Lin Hong's dormitory, could they have also targeted their dormitory?

Zhao Xiaoyan was startled by her being pulled and turned around in confusion, "What's wrong? If you don't hurry, they'll..."

"Don't touch the water yet." Xu Xinghe interrupted her, let go of her hand, picked up the water ladle herself, carefully scooped up half a spoonful of water, and brought it to her nose to smell it carefully.

At first, there wasn't a very noticeable smell, but when she held her breath and tried to distinguish it more carefully, a very faint medicinal smell, similar to the one in the water tank in Lin Hong's dormitory, entered her nasal cavity.

Xu Xinghe's face turned pale instantly, and her hands trembled slightly uncontrollably.

She handed the water ladle to Zhao Xiaoyan, "Xiaoyan, smell this water carefully, does it have a smell?"

Zhao Xiaoyan's heart tightened, and she quickly leaned over to smell it.

At first, she couldn't smell it, but after taking a few deep breaths like Xu Xinghe, her expression suddenly changed. "Yes! There's a medicinal smell! It smells a bit like the rat poison the old doctor mentioned earlier! Could it be... could it be that the water tank in our dormitory has also been poisoned?"

Her voice was filled with fear, and she involuntarily took a step back. "How could this happen? It's one thing that Lin Hong's dorm was poisoned, but how could our dorm be affected too? If only one dorm was affected, we could say it was due to discord between them, but both dorms are like this..."

Zhao Xiaoyan grew increasingly frightened. "Could it be Liu Hu? He was arrested, so his friends came to retaliate against us? And Wang Lili, she hasn't moved back to the female educated youth dormitory yet, could someone have forced her to do it? After all, she helped Liu Hu before..."

“Thinking about this now is useless.” Xu Xinghe forced herself to calm down. She knew that panicking wouldn’t solve anything. “No matter who poisoned them, the most important thing is to get clean water as soon as possible and make soapy water to give them. If we delay any longer, their condition will become more dangerous.”

She took Zhao Xiaoyan's hand. "Come on, let's go fetch water from the well at the village entrance! The well water is flowing, so it'll be fine. You take two buckets, and I'll go get the carrying pole and soap. Let's go and come back quickly!"
