There is a bug in the space? That's called buff!

Everyone was stunned, and the old man asked, "What do you mean, girl?"

"Let me ask you, where does the water you drink come from?" Tang Yiran asked seriously.

The old man wondered what the water had to do with the plague, but he still patiently replied, "The water comes from the Yudai River. We are upstream, and Xiaozhai Village is downstream."

"Then did you boil the water before drinking it?" Tang Yiran asked again.

"Of course you have to boil tea when you drink it, but why don't you need to boil water when you drink it? The water of Yudai River is clear and sweet, so it tastes good even without boiling it." The old man replied.

Tang Yiran shook his head and said, "Wrong! Absolutely wrong! No wonder the plague spreads so quickly!"

The old man was confused at first, but after a little thought, he suddenly understood: "Could it be...could it be that the girl means that this plague is related to water?"

Tang Yiran said solemnly: "Yes! There is a virus in this water. The plague was caused by drinking water without boiling it! The fact that you don't show symptoms is just temporary."

The old man glared at him and said, "Bullshit! I've never heard of that! I've never heard of drinking water being particular! We are all healthy! Didn't we drink the water from the river?"

Tang Yiran was about to speak again, but the old man took out a stick and said to him, "Go away! I won't bother with you because you're a girl! You're just fooling around here!"

Seeing that these people were unmoved, Tang Yiran had no choice but to shake his head and continue walking towards the center of the epidemic area, thinking: Give up the desire to help others and respect the fate of others! Thinking of this, the guilt was not so strong.

Tang Yiran walked past the small village on the outskirts of the city and climbed over a small hill. A boundary marker appeared in front of him with a few big characters on it: Guangming Village.

Tang Yiran walked further in and vaguely saw several low houses next to each other. There were no walls here, and the doors were wide open. People's expressions were desperate and numb, and the light in their eyes seemed to have been exhausted. Everyone was lifeless. Although the god of death had not yet arrived, they seemed to have signed a contract with the god of death. Although they were still moving, they had already lost hope.

Suddenly, a little girl who looked about five or six years old and was covered in dirt excitedly rushed to Tang Yiran. Only her big eyes were clean and clear, and her eyes were full of hope and pleading.

"God?! Are you a God? Lord God, please save my mother! She is very ill and is dying! My mother is all I have! Without my mother, I will have nothing!"

After saying that, she began to kowtow to Tang Yiran while crying.

Tang Yiran immediately felt sorry for the poor girl. She squatted down, helped the girl up and said gently, "Little girl, although I am not a god, I am a doctor. Is your mother sick? Take me to see her quickly, maybe I can save her!"

The little girl immediately stopped crying and smiled, stood up and was about to leave.

"Wait a minute!" Tang Yiran called out to the little girl.

The little girl turned her head and looked at Tang Yiran in confusion, but still stopped obediently. Tang Yiran took out hand sanitizer from the medicine box through the space to help the little girl disinfect her hands, then put a mask on her and disinfected her whole body.

The little girl was quite curious about the mask, so she reached out to take it off.

Tang Yiran didn't say anything, but waved at her. The little girl immediately understood and blinked her big eyes to indicate that she understood.

On the way, Tang Yiran learned that the little girl's name was Yin Shuang'er, and she was a villager of Xiaozhai Village. When the refugees were burning, killing and looting, her mother, despite her illness, took her and other villagers to escape from the clutches of the refugees.

After finally arriving at Guangming Village, Yin Shuang'er's mother's condition worsened. Yin Shuang'er had planned to find other villagers, but they shook their heads. Yes! Besides, they couldn't save themselves, how could they save Yin Shuang'er's mother?

"They couldn't save mother, luckily you, sister, showed up!" Yin Shuang'er said with a happy smile.

Yin Shuang'er's father died in the battlefield while serving in the army in his early years, leaving her and her mother alone in the family. Yin Shuang'er speaks clearly and logically, and Tang Yiran judged through communication with her that the plague should be cholera, and he had some clues.

After walking along a winding path, we finally arrived at where Shuang'er lived. A low and dilapidated thatched cottage appeared in front of us.

"We're here, sister! My mother is inside!" Yin Shuang'er pointed at the thatched cottage.

The tattered wooden door was closed at this time. With a "creak", Tang Yiran pushed the door open and went in. "Cough cough!" Tang Yiran was choked by the dust blowing in his face as soon as he entered the door.

Dark and shabby, this was Tang Yiran's first reaction. It took him a while to adjust his eyes before he could see the furnishings in the house. The furniture in the house was very simple, with a table, two stools, and a bed, and because it had not been cleaned for a long time, a lot of dust had accumulated on the furniture. At this time, Yin Shuang'er's mother was lying weakly on the bed.

"Mom! Mom! I found a female doctor! You can be saved!" Yin Shuang'er said happily as soon as she entered the door.

Yin Shuang'er's mother was so weak at this time that she didn't even have the strength to speak. She just made a weak sound from her throat with difficulty. At this moment, Yin Shuang'er's mother suddenly climbed up with great effort.

Yin Shuang'er saw that something was not right and immediately brought the basin to the bedside. Before she reached the bedside, Yin Shuang'er's mother vomited with a "wow" sound, and the vomit splattered everywhere.

Tang Yiran hurriedly pulled Yin Shuang'er away and went forward to check. The vomit was watery. Looking at Yin Shuang'er's mother, her skin was dry, her eye sockets were sunken, and her cheeks were sunken. She had already shown symptoms of severe dehydration. This condition definitely would not develop into this in a day or two.

"I really don't know how much faith she had to be able to bring Shuang'er here despite being severely dehydrated! This is really a miracle!" Tang Yiran admired Yin Shuang'er's mother very much, and she sighed to herself.

Tang Yiran took out a plastic bag from the space, cleaned all the vomit into the plastic bag, dug a hole and buried it in the soil, and then disinfected the place.

After Tang Yiran mixed the infusion equipment with sodium chloride solution, potassium chloride solution and ciprofloxacin, he began to give fluids to Yin Shuang'er's mother on the spot. Yin Shuang'er's big eyes were full of curiosity. She didn't understand how her sister could put such a big thing into her medicine box. Moreover, she had never seen this thing before. It was really strange!

Seeing that Tang Yiran was working very hard, Yin Shuang'er brought a bowl of water to him. Tang Yiran was really thirsty, so he took the water and prepared to drink it, but the bowl was cold!

Tang Yiran put down the water and asked, "Where does this water come from?"

"The Yudai River next to it! Everyone in our village drinks the water from this river, it's so sweet!" Yin Shuang'er replied, blinking her big eyes.

"This water has not been boiled?" Tang Yiran asked.

"No, I don't boil it! I only boil water for tea, this is just the right way to drink plain water!" Yin Shuang'er answered in a baby voice.

Tang Yiran finally understood why cholera spread so quickly! As long as the water upstream was polluted, everyone in this place would be unable to escape cholera!

Tang Yiran said to Yin Shuang'er seriously: "Shuang'er, remember! You have to boil water before drinking it in the future, otherwise you can't escape this disease! Do you understand?"

Yin Shuang'er heard this and said, "I understand, sister! I'll boil some water for you to drink again!"

Tang Yiran waved her hand and said, "Forget it! It's still early for the infusion. Sister, go out and look around to see if anyone needs help!"

Tang Yiran took out two bottles of mineral water from the medicine box and said, "If you are really thirsty, drink this first! But remember! Your mother can't drink it!"

Yin Shuang'er held the two bottles of crystal clear mineral water as if they were treasures. She had never seen such beautiful bottles before, so she was reluctant to drink them. She thought: This sister must be a god! Otherwise, how could she have so many strange things?

After giving Yin Shuang'er's mother an infusion, because the infusion time was long, Tang Yiran explained the details and disinfected herself again. After walking out of the hut, Tang Yiran felt less depressed. She opened another bottle of mineral water, opened her protective suit and drank some. Then she tidied up her protective suit and decided to go somewhere else to see other people.

It was almost dusk, but the weather was still hot! Tang Yiran walked along the path for a while, and saw a figure carrying a box in a hurry.
