Around noon, Rosen used a wooden boat found by the river to send more than 500 people to the other side of the Bishui River, and gave each person ten kilograms of magic potatoes.

After sending the last of the people away, Rosen took a boat back to the academy by boat. Looking at the crowd on the other side of the Bishui River, he silently thought in his heart: "The road ahead is bumpy, I wish you good luck." ”

With that, he turned and walked back towards the ruins of the academy.

In the ruins around the stone house, people have already begun to get busy.

With Lawson here, there is no need to worry about safety and food for the time being, but the problem of accommodation must be solved immediately. On this winter night, if there is another freezing rain, it will be really unbearable.

Under the command of Lilith and others, people used wood, fur, leaves and other materials found in the ruins to build simple cabins around the stone houses.

In one morning, more than a dozen small cabins around the stone house had been completed, and although the structure was very simple, it was enough to keep out the cold.

Seeing that everyone was sweating and busy, Lawson didn't bother, waved hello to Lilith from afar, and walked into the stone house hall.

The hall was also crowded with people, about seventy or so, all sick numbers, a small number of whom were wounded, and most of them were suffering from a cold. Some were severe, and they also developed high fevers.

Among these patients, the wounded were fine, and the wounds were basically treated. Those adults who suffer from colds and colds are not a big problem, as long as they have enough rest and enough food and water, they can recover quickly. What worries Rosen the most is the group of orphans.

There were more than 40 orphans, and 35 fell ill at one time. When Rosen found them out in the morning, several of the children were already burned, and their bodies were horribly hot, and they were talking nonsense.

At present, the sick orphans are placed in a corner of the stone house, where they sleep on makeshift wooden planks. The wooden bed is covered with a layer of quilts found from the ruins, and a temporary patchwork of wooden screens is erected around these wooden beds to prevent cold wind from pouring in.

When Rosen arrived, Anne and several young women were busy taking care of the children.

"How's it going?" Rosen walked briskly.

Anne was wiping the whole body of a little boy who was only about four or five years old with a damp cloth, and when she saw that Rosen was back, she raised her hand to wipe the beads of sweat on her forehead, and looked happy: "The situation is not bad." We followed the method you said to cool the whole body of the children with high fever, most of the children's body temperature was controlled, and a few of them have already woken up. ”

"That's good, that's good." Rosen's heart was slightly relieved.

He walked briskly over to the wooden bed and began to examine the children's condition. They are all colds and fevers, but the conditions are mild and severe, and the children's physique is also different.

It was a little girl, six or seven years old, with long, thick burgundy hair, but it was as dry as grass. Her skin was very white, and her facial features were very delicate, and when she looked at it, she looked like a doll, but if you looked closely, she would see that her face was gray and her body was quite thin, not much better than the little Alice that Lawson had seen for the first time. On her, she wore a thick cotton skirt with a very ordinary style and materials, and when Rosen first met her, this cotton skirt was covered with a thick layer of mud.

Earlier, Rosen had asked others about the girl's origins, but no one knew her name. Only a middle-aged woman told him that the little girl might be a 'kitten' from Madame Yas's house.

At first, Rosen didn't understand what he meant, but Vincent quietly told him that Lady Yass was the owner of Jasmine's House, the largest brothel in the west of the city. And the kitten is the kind of beautiful little girl who buys it from traffickers at a high price. These little girls are usually orphans from war-torn areas, and the kittens are carefully raised to become Lady Yass as a means of earning money when they grow up.

The little girl's life experience is unusually tragic.

Lawson walked up to the little girl and felt the temperature on her forehead with the back of his hand, it was still very high, but it had dropped a lot compared to the degree of burning in the morning.

'cough~cough~'

The little girl in her sleep made a hoarse coughing sound, and a 'purring' sound came from her lungs, like a leaky bellows.

Hearing this, the young woman who was taking care of the child sighed and said to Rosen, "Master, she has a rotten lung. Looking at this situation, this disease has been around for a while, and it has become so sick that there is no cure. ”

"Hmm~ How do you see that?" Rosen asked, he turned his head to look at the young woman talking beside him, the other party was about twenty-five or sixteen years old, with an ordinary appearance, a fairly ruddy face, some small freckles on the nose, and looked like a very ordinary woman.

The young woman said with sincere fear: "Master, I know some medical skills, and I have opened a herbal medicine shop before, and I have cured many diseases. You see, this little girl coughed with a strange sound in her chest, and the thick phlegm she spit out was still bloodshot, and her body was so thin that only a skeleton remained. In a situation like this, the lungs must be rotting out, and there is no rule of law at all, so you can only wait for death. ”

"It makes a lot of sense. What is your name? Rosen was intrigued. He couldn't keep himself busy alone, and even if he had Lilith, Anne and others to help, he was greatly understaffed, and he needed more helpers, preferably the kind of person with a skill.

"My name is Beyoncé." The young woman whispered.

"Very well, you will take care of these children here in the future, and you don't have to do anything else. Also, you know how to read, right? Rosen asked again.

"Recognize ...... Cognitive. Beyoncé nodded.

Lawson was very happy and said, "Very good." I'll take the time to teach you some more powerful medical techniques, and I'll give you some medical manuscripts. You have to memorize carefully, study carefully, and don't let me down. ”

"Yes, Master!" Beyoncé was pleasantly surprised.

Rosen turned his head to look at the little girl again and said, "You're right, this little girl does have rotten lungs. For this disease, ordinary herbs are powerless, but with the help of some alchemical medicines, there is still hope for a cure. ”

"Alchemy Elixir?" Beyoncé looked at Rosen with awe.

"Don't ask, look carefully, and listen to me."

As he spoke, Rosen took out penicillin, mixed it with sterile water to a specific concentration, drew in the syringe, and then pulled up the back of the little girl's hand, first injected a trace on the skin, and then used magic to detect that there was no allergic reaction, and after Rosen inserted the needle into the vein vein on the back of his hand, imitating intravenous drip, and pushing the medicine little by little.

As he operated, he explained: "There are countless blood vessels in the human body, and these blood vessels are a net, which connects not only the heart, but also the lungs, liver, intestines, stomach, kidneys, and other organs. When the drug is injected into the bloodstream, the flowing blood carries the drug and enters the diseased organs, killing the disease hidden deep in the organs. ”

Beyoncé watched Rosen's series of actions, at first, she was a little scared in her heart, but she was also a doctor before, her mind was more open than ordinary people, and she saw more, after hearing Rosen's explanation, she combined her previous medical experience, the more she listened, the more she felt reasonable.

The fear in her heart slowly faded and turned into admiration.

In the past, when she was practicing medicine, she was also extremely curious about the human body, and she also had many doubts, but no one could answer these doubts for her. Now that Rosen confessed that he was willing to teach her, she hesitated a little and asked, "Master, why does my heart keep beating?" ”

"In my opinion, this is because the heart has to push the blood up and down the body, and when the heart hears it, the blood flow stops, and the person dies."

"Then why does the blood flow?" Beyoncé immediately asked.

This is a very complex issue, and it is impossible for non-specialists to explain it clearly. Naturally, Rosen couldn't, and he only knew some basic principles. Of course, it is enough to solve the puzzles of a pure novice in the other world.

He thought for a moment and said, "It seems to me that the human body is like a burning furnace, and the flame in the furnace is life. I ask you, what do you need to do to keep the flame alive? ”

Beyoncé thought about it seriously and said, "You need enough firewood. ”

"Well, that's a very important condition, but is there anything else?" Rosen asked.

Beyoncé pondered for a while, and then said: "Well~~~ It is necessary to keep the wind duct of the furnace unobstructed and not block the wind." ”

"That's right. The wind must flow all the time for the flame to remain unquenched. For life, blood is another form of wind, and the bread you eat every day is equivalent to the wood in the stove. Therefore, if you want the fire of life to burn all the time, the wind cannot be stopped, and the firewood must be added all the time. ”

"Ahh Beyoncé screamed, and the whole person froze.

She couldn't help but confirm each other with Rosen's words in the process of practicing medicine, and the more she confirmed, the more she felt that Rosen was correct, and she had a sense of transparency in her whole person.

When she came back to her senses, Beyoncé was already convinced: "Thank you for the advice." ”

Rosen shook his head and smiled: "I just said a popular truth, but real medicine is profound and meticulous, and there can be no ambiguity...... Okay, I'm pretty much medicinal. When I'm not around, you have to pay attention to this little girl and tell me immediately if there is any unusual movement, understand? ”

"Yes, Master." Beyoncé nodded repeatedly.

After treating the 'kitten', Lawson walked over to the next burning and confused little boy and began to check his condition, Beyoncé followed him step by step, looking attentive and not daring to slack off in the slightest.

Just checked and treated one by one, and when Lawson finished treating the last orphan, there was a soft sound of "um~" from the 'kitten', and he woke up. Not only did she wake up, but she also sat up on her own from the wooden bed.

She clasped her hands on her knees, her body curled up in the corner, and a pair of crimson eyes looked at Rosen and them cautiously, and when Rosen looked over, she immediately lowered her head as if frightened, and did not dare to look at anyone.

Such a demeanor is like a stray kitten that has been abandoned.

Anne on the side saw that her heart melted, and she hurriedly walked up, gently covered her with a piece of cotton cloth, and asked softly, "Little one, what do you think?" ”

The little girl's body trembled slightly, and she did not speak.

Lawson also walked over, sat down next to the little girl, patted his chest first, made an inhalation motion, and then asked, "Is it uncomfortable?" ”

The little girl hesitated for a moment, but did so, and when she was done, she nodded and shook her head again.

"What does that mean?" Anne couldn't read it.

Rosen understood, and he asked, "It's uncomfortable, but it's a little more comfortable than before, right?" ”

The little girl nodded slightly.

"It must have taken effect!" Beyoncé was pleasantly surprised.

Rosen was also relieved in his heart, he thought about it, took out a magic potato and handed it over: "Are you hungry?" ”

The little girl nodded slightly, trying to reach for the magic potato, but when her hand reached a little, it retracted like an electric shock, and she didn't dare to take it.

Beyoncé saw the little girl's hand and whispered, "When she has rotten lungs, she will definitely be abandoned by Madame Yas." When she wanders on the streets, she should have been deceived by many people with food. ”

"Oh~ what a poor little thing."

Anne's eyes were red, and she took the magic potato, broke a small piece, and handed it to the little girl's mouth.

This time, the little girl hesitated to open her mouth to eat, and when she was done, her eyes were staring at the magic potato, her eyes full of longing.

Rosen smiled with relief: "She's hungry." Annie, tell her to eat slowly, don't choke. ”

"Don't worry." Anne nodded.

The orphans' treatment was over for the time being, everything was in a state of ruin, and Lawson still had a lot to do, so after a little rest, he prepared to leave the cubicle.

As soon as he walked to the door, Rosen suddenly felt something unusual behind him, and immediately after, he heard Annie's exclamation: "It's so hot!" ”

Rosen was startled and immediately looked back.

He saw that Anne, who was holding the little girl, had jumped to the side, and the small quilt she had covered the little girl before had turned into ashes in less than half a second.

The little girl cowered by the wall, already frightened.
