Jichang County, Gangning City, Donghu Province, a remote mountain village.

There is a family at the east end of the village, three blue brick houses, and on the outer wall of the gate there are two large characters written in red paint, "clinic".

This morning, just after dawn, the door of the house opened, and a young man with a one-year-old child in his arms hurried out the door, looking at the empty road, the man stopped, stared into the distance, and was silent for a long time. After a long time, the man let out a heavy sigh, he carefully put away a letter in his hand, and muttered to himself with a depressed expression: Go, you are still gone after all, you can rest assured, although my son is not my biological son, I will definitely raise him as my biological son, and when my son grows up, I will tell him the truth and let him choose for himself.

The man's smile was bitter, but the child in his arms didn't know anything, he put his thumb in his mouth, he was eating deliciously, and his big smart eyes were looking around, perhaps searching for his mother.

Twenty years later......

The weather in June is like a hot sun, and the scorching and dazzling sun shines on the body, making people dizzy. Jin Cheng walked to the shade of the tree, sat on the ground, panted heavily, reached out and took off the straw hat on his head, fanned it a few times, and said to himself: This ghost God, I want to heat Lao Tzu to death! It was only half an hour of climbing the mountain, and I was soaked with sweat, and water could be wrung out of my crotch.

I took out the water cup in my backpack, poured a few sips of mountain spring water, and wiped the sweat on my face with a towel, feeling a little refreshed. Suddenly a cool breeze blew, Jin Cheng hurriedly lifted the T-shirt and let the wind blow on his thin chest. Recite.

But the good times didn't last long, and the cool breeze blew slowly for two minutes before stopping, and the air became hot and dry again.

Jin Cheng looked up at the top of the mountain, then looked back at the bottom of the mountain, and said in his heart: I have finally climbed more than half of the distance, and I rushed to the top of the mountain with all my strength, there must be wind on the top of the mountain, and I will have a good rest when the time comes.

Listen to the villagers, there is a cave on the back of this mountain, the villagers call it "fairy cave", legend has it that in ancient times, there were gods who fell on their feet, Jin Cheng is coming to the "fairy cave" today.

The wind on the top of the mountain was very strong, but there was not a single tree on the top of the mountain, and the sun was even hotter, Jin Cheng could only sigh to himself that he was unlucky, and chose such a hot weather to climb the mountain, if he fell on the mountain due to heat stroke, no one would know.

Speeding up the pace, coupled with the descent again, Jin Yu quickly reached the entrance of the cave halfway up the mountain.

The height of the entrance to the cave is about two meters, and the width is narrow, and one person has to lean slightly sideways. Jin Yu walked down the simple steps, saying that the steps were actually hollowing grooves in the stone. As soon as he walked a few steps, Jin Yu felt that the sweat on his body was dry, but it was a little cold, which showed that the humidity in this cave was not ordinary.

Walked down about thirty meters, came to the bottom of the cave, the light in the cave was not good, Jin Cheng turned on the flashlight, observed the surroundings, this is a typical cave structure, the area is the size of a basketball court, the top of the cave hangs with strange stalactites, from time to time there is water dripping from the top of the cave on the body, cold and cold.

After walking around the cave, Jin Cheng felt interested, there was really nothing to see here, compared to the majestic and majestic Taiji Cave he had visited, he felt that this place could only be regarded as a pit, he was "pitted" by the female accountant of the village, and he was fooled to come here to suffer.

Thinking of this, Jin Cheng hated it so much that he secretly swore that he would settle accounts with Na Nizi when he went back.

Just when Jin Cheng was about to go out, a small hole in the ground caught his attention, he suddenly wanted to get into it to see, this kind of idea lingered once it was generated, after a struggle of ideas, Jin Cheng didn't care about the dirt on the ground, lying on the ground and crawling into the hole.

Fortunately, Jin Cheng's body was thin and weak, and he could barely pass through the guò hole, after entering, the space inside was a little more spacious, and he climbed about two meters into it was a right-angle turn to the right, he finally turned the corner, Jin Cheng felt that his left hand seemed to be pierced by something, he raised his left hand, and saw that a small hole was cut in the palm of his hand, and blood flowed out.

He shone his flashlight at the ground, and found that it was a metal object peeking out of the ground with a sharp corner, and there were still blood stains on it, presumably it had cut his hand.

The wound on his hand was not deep, and the bleeding quickly stopped. Jin Cheng was curious about what was going on underground, so he took out the knife he carried with him and dug along both sides of the metal block, and soon a metal block slightly smaller than the palm of his hand was dug out.

The metal block is a cube, less than two centimeters thick, the whole body is dark green, the surface texture is very complex, and a kind of simple and cangsang breath comes to the face. Jin Cheng took it in his hand and looked at it several times, but he didn't recognize what metal it was, but he found a strange phenomenon, the blood stains on the metal block were slowly fading away, until it disappeared completely, and suddenly the metal block bloomed with a dazzling light, and Jin Cheng, who bore the brunt of it, directly lost consciousness.

I don't know how long it took, Jin Cheng woke up slowly, his first feeling was a headache, as if a lot of things had been stuffed into his head, and then he fainted again.

When he woke up again, Jin Cheng felt that his head was no longer so painful, and there was a slight swelling pain, he felt it carefully, and found that a lot of information had been added to his head out of thin air.

After half a ring, Jin Cheng finally figured out what was going on, his mouth opened wide in surprise, his eyes widened, and he shook his head, and poked the wound on his left hand with his fingers, which was very painful. Convinced that it wasn't a dream, his expression changed from shock to ecstasy, and then he burst out laughing.

Forgetting that he was still in the cave, when he looked up, his head hit the stone wall, and the pain made him bared his teeth and cracked his mouth, but he was still happy.

It turned out that the piece of metal was left by a person named Lin Bien, who was a cultivator, who gave up the opportunity to be reincarnated before the limit of his lifespan, and sealed the very painful way of stripping the soul mind that he had learned in his life in this soul stone, and left it to someone who was destined to do so, just to perfect and carry forward his original cultivation exercises.

This set of cultivation exercises is called "Immortal Doctor Speed", when he first saw this name, Jin Cheng was slandered, can the Immortal Doctor be fast? He thought of the crash courses in society that only make money and ignore quality.

However, after learning the latter information, he couldn't help but be overjoyed, this Lin Bien is really a genius, he actually created an original cultivation method, and found another shortcut to use the power of merit to assist spiritual power cultivation, so as to achieve twice the result with half the effort.

Since more than 700 years ago, the last group of Jindan stage cultivators withdrew from the earth, the group of cultivators has gradually faded out of the world's sight, and five hundred years ago, the ancient martial arts sect dominated Huaxia, and no cultivators have appeared since then.

Lin Bien studied under Baicaomen, which is a relatively rare sect of doctors in the cultivation world, and its status in the cultivation world is not low. When the predecessors of Baicaomen left, they took away all the few elixirs planted in the sect, and without the elixir, they could not refine the elixir, without the assistance of the elixir, Lin Bien felt that he could not break through to the Dan period, in his later years, he was committed to research and innovation, and finally let him study the practice of "Immortal Doctor Quick", but he had no time to accumulate the massive merits needed, so the cultivation always stayed in the late stage of foundation building, and finally died five hundred years ago.

In today's earth, where spiritual energy is scarce and the treasures of heaven and earth are gone, it is almost impossible to cultivate the truth, even if a person with outstanding talent spends his life and energy, he can only reach the sixth level of qi refining at most, and he can't even cast the most basic five element spells, and his strength can only be equivalent to that of a martial artist in the late stage of dark energy.

And above the dark energy, there are a large number of masters of transforming strength, even congenital powerhouses, children in big families, it is normal to reach the transformation period at the age of forty or fifty, which is also the reason for the decline of Daozhì Xiuzhen and the rise of ancient martial arts.

Jin Cheng got this soul stone, which was equivalent to getting Lin Bien's inheritance, and a trace of Lin Bien's soul left in the world dissipated, and he didn't leave a word before leaving.

After Jin Cheng slowly exited the cave, he kowtowed three times to the entrance of the cave, which could be regarded as a tribute to Master Cheap and thanked him for keeping the inheritance. After saluting, he walked towards the exit, and when he came to the outside of the cave, he looked at his watch, it was already six o'clock, the sun was about to set, and he estimated that it would be completely dark in an hour at most, and he had to hurry back, he did not dare to wander alone in the mountains in the dark night, but there were wild beasts on this mountain.

Gangtou village clinic is located next to the village department, is the village in four years ago to fund the construction of three bungalows, Jin Cheng came here a week to take over the work of the old village doctor, this is where he will work and live in the future, he will be the innermost half of the house as accommodation, the rest are used as medical rooms, the problem of eating by the village party secretary is specially approved in the village canteen to solve, as long as a small amount of food can be paid, enjoy the same treatment as village cadres.

Secretary Liu's care made Jin Cheng very moved, to be honest, if the village does not solve the problem of eating, he can only eat instant noodles every day, he has grown so big, he has not cooked a meal.

It's just that he came back too late today, the gate of the village has been closed early, and the canteen Lao Wang doesn't know where to go, maybe it's in the east of the village, Widow Zhang's house is ploughing, maybe it's not...... This is not what Jin Cheng cares about, he only cares about what to eat at night, and on the way back, his stomach has been protesting.

When Lao Wang came back, he didn't know when it would be, so Jin Cheng had to go to the small shop in the village to buy something to fill his stomach.

The small shop in the village is only about 100 meters away from the village, Jin Cheng first plugged in the electric kettle to boil water, and when he came back from buying instant noodles, the water boiled, and immediately soaked the noodles, without delaying time at all.

Just as he was taking his first bite of noodles, he heard someone knocking on the door outside, "Doctor Jin, Doctor Jin, open the door." ”

Listening to the anxious voice, Jin Cheng knew that there was an urgent matter coming to the door, so he quickly ran to the door and opened the door of the health room.

"Doctor Jin, come on, my old Yao fell and broke his head, and he bleed a lot." A middle-aged woman with a delicate appearance and a look of about forty years old stood at the door, with an anxious look on her face, and when she saw Jin Cheng open the door, she immediately told him the reason for the incident, and took Jin Cheng's arm and asked him to follow her.

"Eldest sister, you wait, I'll take something, I can't go with you empty-handed!" Jin Cheng broke free of the middle-aged woman's hand and walked towards the counter.

"Oh, yes, yes, I'm in a daze." The middle-aged woman pulled the hair in front of her forehead and said reproachfully.

Jin Cheng's movements were very quick, and he took a debridement bag and followed the middle-aged woman out. The two trotted all the way to the middle-aged woman's home five minutes later.

A middle-aged man was lying motionless on his back on a cool bed, and a teenage boy pressed the top of his head with a towel, and there were blood stains on the ground and on the cool bed, and the towel was also stained red.

Jin Cheng chuckled in his heart, this can't be death! He hurriedly stepped forward and felt his pulse, fortunately the pulse was normal, and he was relieved to see that his breathing was steady.

After opening the debridement bag, skillfully putting on gloves, and preparing the stitches for stitching, Jin Cheng asked the little boy to take the towel away.

The little boy looked at his mother hesitantly, and when he saw that his mother nodded, he slowly took the towel away.

Jin Cheng had done a lot of minor surgeries such as debridement and suturing during his internship, and he took a look at the wound, which was about three or four centimeters long, and the wound was still oozing blood. It is not difficult to deal with such a head injury, first clean the hair around the wound, then disinfect, stitch three stitches, and soon Jin Cheng called it a day.

The middle-aged man who was injured from beginning to end didn't say a word, just snorted a few times when he was stitching it up.

Although Jin Cheng felt strange, he didn't say anything, packed up his things and left.

"Doctor Jin, thank you, I'll take the miner's lamp to send you back, it's dark on the way." The middle-aged woman said gratefully.

"Okay then." Jin Cheng did not refuse, his days in Gangtou were still short, he didn't know much about this family, and he was also very curious about this man's situation, and he didn't bring a flashlight, so he really couldn't see the road.

On the way, without waiting for Jin Cheng to speak, the middle-aged woman made the situation at home clear to him like pouring beans into a bamboo tube.

The middle-aged woman's name is Li Laifang, and the injured man is her husband Yao Luquan, 41 years old this year, two years ago, Yao Luquan suddenly fell ill while working on a construction site in the county seat, and was sent to the county hospital to be diagnosed with cerebrovascular accident, which is commonly known as stroke.

Although the treatment was timely and his life was saved, he still left the sequelae of Yan zhòng. After two years of treatment, his condition has improved, and now he can walk slowly and speak some simple words, but his ability to take care of himself is very poor.

"Aunt Li, does Uncle Yao have a history of high blood pressure?" Jin Cheng, who had been listening quietly, suddenly asked.

"Yes, my family has high blood pressure for several years, and the doctor told him to take medicine to control his blood pressure, but he never listened, he was very stubborn and didn't take medicine, and said that his body was very good, what kind of medicine to take! Unexpectedly, I had a stroke later, and the doctor also said that it was caused by high blood pressure. He can't regret it, but what's the use? A few months ago, I took him to the city hospital for a follow-up, and the doctor said that his recovery was not good, and he insisted on passive exercise, combined with traditional Chinese medicine and acupuncture to treat him. Later, I found a TCM expert and treated my family with acupuncture for a month, but the effect was not good, so I had to give up again. The most important thing is that the family cannot afford it, so in order to treat him, we not only spent all our savings, but also borrowed a lot of money from relatives and friends, and in this way, he refused to be treated anymore and insisted on going home. Li Laifang looked blankly at the dark front, Jin Cheng could feel her confusion and helplessness, but he couldn't do anything, and he couldn't even say words to comfort her.

Returning to the village clinic, Jin Cheng's mood became heavy, thinking that Yao Luquan was in the prime of life and lost his ability to work, and a family collapsed, which is a typical poverty caused by illness, although it is caused by his own negligence, but it is also worthy of sympathy.

Jin Cheng really wanted to help this family, after he ate the instant noodles without knowing the taste, he hurriedly went to the back yard to take a cold shower with tap water, and kneaded his clothes in the basin casually a few times before drying.

Jin Cheng thought that if he wanted to solve the world's medical problem of sequelae of stroke, maybe he could find a way from "Immortal Doctor Express", after all, the methods of the immortal family cannot be deduced by common sense, which is worth looking forward to.
