Huachen country, the branch of Longji Mountain in Qingyue Mountains, there is a large canyon that is hundreds of miles long - Longxi Gorge, the mountains on both sides of the canyon are steep, the ravines are vertical and horizontal, the precipices are towering everywhere, the vultures enter the clouds, the cliffs are strange and rocky, and the vines and grasses are all over; The ambergris stream at the bottom of the valley passes through the valley, the flowing water is turbulent, the roar bursts, the vegetation on both sides of the bank is dense, the trees are towering, the flowers and plants are strange everywhere, lush and green, rare birds and beasts are infested from time to time, the animal and plant resources are very rich, known as the "natural medicine valley".

At this moment, on a cliff, a thin and agile young man in Tsing Yi is picking medicinal herbs, seeing that his body is as light as a swallow, like a spirit ape, with five fingers like a hook, and his feet like nails and rivets, looking at the cliff as flat ground, his body is flashing and moving and constantly climbing and jumping between the cliffs, and from time to time he puts the picked medicinal materials into the back basket behind him, his expression is not like labor, but an expression of intoxication.

The boy's name is Gongsun Yan, and he is a child of the Gongsun family.

The ancestral land of the Gongsun family is in Luming Mountain in the east of Huachen Kingdom, practicing medicine for generations, is a famous medical family in Huachen Kingdom, most of the children of the family are engaged in medicine-related industries, and there are many people who serve as imperial doctors in the palace, but most of them practice medicine or do medicine in the people, and the children of the family are assigned to practice medicine in various parts of Huachen Kingdom once they become adults, and there are many people who serve as military doctors in the army, but they are mainly children of the family sideline.

Gongsun Yan's father, Gongsun Dian, was assigned to practice medicine in the town of Suishui, which is far away from the family's ancestral home, when he was just an adult, and assisted his second brother in running a pharmacy for many years, and three years ago he was conscripted into the army to become a military doctor. Influenced by his family, Gongsun Yan practiced medicine from his father since he was a child, learned various medical skills, read medical classics, and also learned various techniques for distinguishing and collecting medicines, and studied the medicinal properties, pharmacology and preparation methods of various medicinal materials. He was gifted with great intelligence, coupled with extraordinary perseverance and hard work, and at the age of 12, he had the demeanor of a doctor.

"Young master, young master, it's not good, something happened to the master", suddenly, a rapid shout came from the dense forest under the cliff, interrupting Gongsun Yan's action of collecting medicine, he looked down, and saw the servant Zhong Ren running out of the forest in a hurry, waving and shouting to him.

Gongsun Yan hurriedly stopped, his body was smart, he quickly climbed down the cliff, and came to Zhong Ren in the blink of an eye:

"Uncle Zhong, what's wrong with my father?"

"The master was injured and sent back, I don't know what the situation is, Madame asked you to go back quickly." Zhong Ren replied.

Gongsun Yan's heart tightened, and he rushed to his home, and Zhong Ren hurriedly followed.

Zhong Ren is a servant in Gongsun Yan's family, but not a slave, but an injured person who Gongsun Dian treated on the way to practice medicine many years ago. Zhong Ren is loyal and reliable, and has been trusted and respected by the Gongsun family for many years.

The two of them traveled all the way, usually more than two hours away, but today they rushed back to Dishui Town in less than an hour.

The town is surrounded by mountains on the east, west and north, and faces water in the south, so it is named after the river that flows through it. The town is not big, the cross street in the town divides the town into four areas: northeast, southeast, northwest and southwest, the permanent population in the town is only tens of thousands, although it is not a densely populated city, but because it is the only place for the east entrance of Longxi Gorge, it is usually bustling, relying on the unique advantages of "natural medicine valley", the town of Pishui is the famous distribution center of medicinal materials in Huachen country.

After Gongsun Yan's master and servant entered the town, they quickly passed through the town and rushed to their home in the northeast corner of the town.

At this time, in the bedroom of Gongsun Yan's house, Gongsun Dian was laid flat on the bed, his chest was wrapped with bloodstained gauze, his face was blue and gray, his eyes were closed, his breath was weak, and the middle-aged man who was over forty years old was taking his pulse, Gongsun Yan's mother Feng's eyes were red, holding her youngest son Gongsun Sheng in her left hand, and her youngest daughter Gongsun Yao in her right hand Standing anxiously next to her, the two children's faces were covered with tears, staring at their father silently, and the room was very quiet.

"Second brother, how is Xianggong's injury?" Feng asked.

The man waved his hand, did not answer, took out a pair of scissors from the cloth bag he carried with him, and began to gently cut the gauze wrapped around Gongsun Dian's body.

At this moment, Gongsun Yan came to the house sweating profusely, and saw his father lying on the bed with his brows furrowed, and the second uncle Sun Rui was carefully peeling off the gauze from his father's wound, Gongsun Yan walked over gently, and was about to open his mouth to ask, Gongsun Rui raised his head and stopped him with a stern look, he looked at his mother again, and Feng Shi also shook his head slightly to signal him to silence.

Gongsun Dian has a total of four brothers and sisters, the parents are still alive, the eldest brother Gongsun Zheng and the younger sister Gongsun Ying stayed with their ancestral parents, and the second brother Gongsun Rui was assigned by the family to practice medicine in Taishui Town very early, and at the same time ran a pharmacy. Gongsun Rui also had the experience of serving as a military doctor in his early years, and after finishing his military career, he still returned to Dishui Town to practice medicine. Huachen Guo's requirement for military doctors was to serve in the army for three years in peacetime, and it was extended to five years in wartime, which was when Huachen Kingdom was at war with the neighboring Rampant Yuan State, and Gongsun Dian's military years were also extended accordingly.

Gongsun Yan saw that the second uncle was examining his father's injury, so he immediately took the spare medicine box at home from the living room, moved a small table, took out the medicine and medicine in the box one by one, and placed it next to the second uncle, Gongsun Rui glanced at Gongsun Yan with an approving eye, waved his hand again, signaled the three of Feng's mother and son to leave, and then began to sort out Gongsun Dian's wounds, leaving Gongsun Yan to wait beside him.

After a while, Gongsun Dian sweated on his forehead, his breathing became short, Gongsun Yan's eyes were red and nervous staring at his father to stop talking, Gongsun Rui immediately stopped his hand movements when he saw this, his eyes looked at the table, Gongsun Yan hurriedly picked up a porcelain bottle marked with the words "Mixian San" from the table and handed it to the second uncle, Gongsun Rui shook his head slightly and said:

"Your father's body is extremely weak, he can't be anesthetized, and Mixian San is not suitable, so he can only have local anesthesia, and bring bowls and wine."

Gongsun Yan immediately ran to the living room to get the bowl and soju, Gongsun Rui took out a small porcelain bottle from his arms, took out a trace amount of white powder with a horn medicine spoon and added it to the small bowl, and very carefully dissolved and mixed with soju.

"This is extracted from the internal organs of puffer fish in the Pishui River, although it is extremely poisonous! However, the external application after microdilution can play a local anesthetic effect," Gongsun Rui said.

"Ahh Is it a 'drunken three lives' that have no cure? Gongsun Yan was surprised.

"Yes, this medicine should be used with care, an overdose can cause paralysis!"

After speaking, Gongsun Rui picked up the wolf brush, carefully applied the dissolved "Drunk Sansheng" brush to Gongsun Dian's wounded area, waited for a while, and began to gently touch the wound with a small wooden pestle. First carefully remove the blood stained gauze adherent on the surface, as the gauze continued to peel off, the wound gradually appeared, Gongsun Rui's eyebrows were furrowed, this was obviously a palm wound, and the injury was not treated in time, the bandage was extremely rough, and the wound had begun to suppurate and ulcerate.

Gongsun Rui used tools such as a knife, flat-edged knife, scissors, tweezers, etc., to cut open the wound, cut off the dead rotten skin, remove the carrion and blood clots, etc., clean the wound with salt water, and after completing a series of debridement operations, then use the orthopedic technique to reset the injured bone as much as possible, and apply the ancestral "saprophytic muscle ointment" and "continuous tendon bone ointment", and then carefully bandaged it, fixed it with an arc splint, and took out a pill from the medicine gourd he carried, and instructed Gongsun Yan:

"Immediately dissolve it with water and give it to your father, and change the dressing once a day in the future."

"Okay, second uncle, I remember," Gongsun Yan responded, took the pill and immediately handed the towel to Gongsun Rui to sweat, and then took the water and medicine and gave it to Gongsun Dian to do.

Seeing that Gongsun Dian's breathing began to gradually calm down, Gongsun Rui and Gongsun Yan gently exited the bedroom. In the living room, the Feng family and the others were waiting anxiously, and when they saw the two uncles and nephews coming out, they hurriedly got up to greet Gongsun Rui and asked to sit down, and after serving tea, they asked:

"Second brother has worked hard! What about the fairness? ”

Gongsun Rui's face was solemn, and he pondered for a moment and said, "The situation is not good!" First of all, who sent the third child back, what happened? It turned out that Gongsun Rui was out in the morning and rushed over immediately after hearing the news when he came back, and he didn't have time to ask about the details of Gongsun Dian being injured and sent back.

When Feng heard this, his eyes immediately burst into tears, and the two children also wept bitterly when they saw this. Feng Shi choked up and replied:

"Early this morning, Yan'er went to the valley to collect medicine, about an hour after he left, he heard someone calling outside the courtyard, Zhong Ren went out to see, it was the two military masters who sent Xianggong back with pack horses, saying that they were injured on the front line, and left in a hurry after helping us carry Xianggong into the room, and when he left, he also instructed us to find someone to treat Xianggong immediately!"

Gongsun Rui couldn't help frowning after hearing this, and fell into deep thought.
