Two days before the Double Moon Festival, Mu Huaixi had already made ointments and oils from the herbs he had collected last time, and also made a batch of medicines to treat diarrhea and dysentery.

The climate here is hot and humid, and most of the soldiers who come here are not locals. The first reaction to acclimatization is vomiting and diarrhea. Even the "old people" who have been here for a while may get diarrhea due to wind, eating the wrong things, or drinking water that has been left for a long time.

Mu Huaixi's batch of medicine was indeed a timely relief, but in pursuit of efficiency in medicine production, her method of handling the medicinal materials was a bit rough. This batch of powder medicine for treating diarrhea gave off a strong pungent smell, and was called a magic emetic by Ai Taoyu.

But this medicine is effective once taken. Diarrhea and dysentery can be cured by taking two or three pills. It really makes people love and hate it.

Because of the pharmaceutical production in the past few days, Mu Huaixi had not had a good rest for several days. She was supposed to be on duty that night, but Qin Wenlong and Li Ying came to her together and said that they had agreed to help her keep watch.

Qin Wenlong scratched his head. "I said I could do it on my own, but Li Ying insisted on sharing the night shift with me."

"You also have to be on duty tomorrow," Li Ying said, looking at Mu Huaixi with a smile. "Doctor Mu, we have to leave tomorrow. I saw Doctor Luo tinkering with his bicycle again. I'm afraid it will take him a whole day to ride there. You should get a good rest tonight."

"That's right. If not, I'll join in. Let's divide it among the three of us. The night will pass quickly!" Ai Taoyu also came over. She was hit in the eyelid by a flying insect when she was taking a shower the day before yesterday. Now there is a red and swollen spot on her eyelid, which looks like she was punched.

Li Ying turned her head and looked directly at her red, swollen, drooping eyelids. She suppressed her laughter and patted them, "You'd better get some sleep, so that your other eye doesn't get swollen too."

"Alas," Ai Taoyu also knew what she looked like now. If she were in the city, she would have wrapped herself in gauze or asked for leave to stay at home instead of going to work. But now she was in the mountains and facing a group of rough men, and she was too lazy to clean up.

Mu Huaixi had already applied medicine to her, but her skin was delicate and it would take a while for the medicine to wear off. Seeing that they were all helping him keep watch, he couldn't help but feel warm in his heart. He handed over the prepared medicine bags one by one, "There are all kinds of medicine in them. Take them, just in case."

Li Ying glanced at her and accepted it silently, but Ai Taoyu was nonchalant, "Don't I have you? Do I still need this?"

Mu Huaixi didn't directly mention that their medical station might have to move along with the battlefront. He just smiled and said, "I'm going to be away for several days. I'm worried about you guys!"

The next morning, Mu Huaixi woke up full of energy and found a mule cart parked in front of the bamboo building!

"Where did this come from?" Mu Huaixi was stunned. He walked around the calm mule twice, then looked at the blue cloth and salt bags tied to the cart. Only then did he accept the reality that he had to ride in a mule cart.

Doctor Luo came out pushing a bicycle. Seeing her surprised look, he couldn't help but laugh. "Xiao Xiaowu found the mule cart. I'll ride the bicycle and you can take the car. Xiao Wu is the only one who can drive. The three of us will set off now."

Xiao Wu is a local. He is short and has dark skin. What impresses people most is his bright eyes, like two black pearls.

"I'm riding in a car?" Mu Huaixi looked up in surprise, his eyes flickering between the mule cart and the bicycle. He shook his head and replied, "Let's switch."

Dr. Luo did not object, but he did not give Mu Huaixi the chance to change bikes along the way, so she sat in the car all the way, occasionally getting off and pushing the bike when she encountered a difficult road. After a day and a night, she finally arrived at the destination.

The market was located in an open space, and there was a village nearby where Xiao Wu's relatives lived. They had been told they could stay overnight there, but they arrived a little late and their place had already been rented out by someone else.

Black Pearl Xiao Wu negotiated with the villagers for a long time before they found her a bed, but the other two could only make do with one bowl of rice on the mule cart in the yard.

There are not so many things to pay attention to when you are away from home, but Mu Huaixi still fetched a basin of water and wiped the sweat off her body before going to bed. The person who shared the room with her was the host's little daughter Xiaoya, who was about eleven or twelve years old and was full of curiosity about her.

Xiao Ya also has dark skin like Xiao Wu. She sits on the wooden bed at the head of the house, swinging her feet as she watches her busying around.

Mu Huaixi washed the clothes that were soaked with sweat and hung them on the rack in front of the window. She turned around and saw Xiao Ya looking at her curiously.

"Here," Mu Huaixi took out a candy from his pocket and handed it over. The little girl took it timidly and timidly showed her a few small teeth.

Mu Huaixi gave her a soothing smile and was about to go to sleep on the wooden bed on the other side of the room, but he found an unusual redness and swelling on Xiaoya's calf.

She turned around and squatted down, holding Xiaoya's bamboo-thin calves. Feeling Xiaoya tremble, she quickly raised her head and smiled.

There were no lights here at night, and it was hard to see clearly in the moonlight. Mu Huaixi touched it with his hand and felt some mucus, so he asked her, "Did you go into the water?"

Xiao Ya was peeling the candy wrapper and looked at her confusedly when she heard that.

Mu Huaixi then realized that she didn't understand what she was saying. In fact, she didn't understand the local dialect either. She could only take out alcohol and cotton from the package and gently help Xiao Ya disinfect and apply medicine.

At first the little girl was very resistant, especially when the alcohol touched her body, the pain made her almost jump up, but Mu Huaixi's concerned expression and gentle movements slowly made the little girl relax. The wound was cleaned and medicine was applied.

Perhaps it was the coolness of the medicine, perhaps it was that the wound no longer hurt, or perhaps it was that the candy she gave was too sweet, but the little girl's slightly frown completely relaxed and she gave her a sweet smile.

With Xiao Wu's help, Buhe's salt was sold the next day. If he hadn't been thinking about exchanging it for some herbs at the market, the whole bag of salt would have been bought up by everyone in the village.

Mu Huaixi finally understood why salt was considered hard currency. Salt was also produced here, but the green rock salt produced from rocks tasted bitter and astringent, which was completely different from the white salt they brought.

Therefore, the households that can afford white salt are also those with some savings in the village.

Xiao Wu exchanged a bag of salt for a lot of food, filling up half of a mule cart. He exchanged the cloth for some dried meat, dried vegetables, etc. He also exchanged it for some tobacco that people here usually chew, which is said to be able to refresh the mind and relieve pain.

Mu Huaixi walked forward curiously and smelled it, and found that it was indeed roasted smoke. He also knew that night duty was extremely hard, so he didn't say anything.

With Xiao Wu's help, they exchanged for what they wanted at the market. Mu Huaixi even saw many medicinal herbs that she had only seen on trees. After repeated comparisons and selections, she exchanged for some that could save her life.

The fair went extremely smoothly and successfully, but unexpectedly, they were attacked on the way back.
