In the Qilin Mountain Village, Zhuang Lao's house, Zhuang Lao took Zhao Feng's pulse with a solemn face, and after a long time, he shook his head in confusion and let go of Zhao Feng's hand.

"The venom in your body is gone...... People who have been bitten by the Snake King, I have never seen a hundred, there are eighty, no one has survived, and it is even more unheard of for you to dissolve the snake venom by yourself, it is not an ordinary poisonous ...... after all" Zhuang Lao realized that Zhao Feng's blood may have some kind of secret that can dissolve the poison, and if he can obtain his blood, he may be able to completely resolve the threat brought by the Snake King to the villagers in the future.

But the doctor is benevolent and selfless, so naturally he will not act in a small way, and even in order to avoid Zhao Feng from causing unnecessary trouble, he specially instructed Ergouzi not to tell what he saw here today.

"I usually exercise a little, maybe my immunity is a little stronger than ordinary people...... My name is Zhao Feng, thank you Mr. Zhuang for your rescue!" Zhao Feng said and solemnly expressed his gratitude.

Zhuang Lao patiently complained secretly: If you can be immune to the venom of the snake king with a little exercise, what else do you need a doctor to do?

"I just asked someone to carry you back to the village, I don't think you should be a person from the neighborhood, how could you pass by Qilin Mountain? You must know the remoteness of this place, few vehicles approach it all year round, and the people in the village have to walk for a day and a night if they want to enter the city. Zhuang Lao asked as he got up and lowered his cuffs.

"Subject to others, involuntarily. Zhao Feng could only answer like this.

Zhuang Lao nodded, and no longer asked, and was thinking about whether to let the villagers take Zhao Feng into the city, when there was a breathless cough from the inner room.

"It's not good!" Zhuang was startled and hurriedly rushed into the inner room.

"Alas, it's hard for Elder Zhuang and the maid to ......," the young man Ergouzi, who looked loyal and honest on the side, couldn't help but sigh.

"Brother Ergou, is Zhuang always in trouble?" Zhao Feng asked.

"You can call me Ergouzi, that's what everyone in the village calls me, Zhuang Lao's trouble began eleven years ago, the cub is Zhuang Lao's granddaughter, she was born with a serious illness, and she hasn't been able to get out of bed for eleven years, Zhuang Lao has been looking for a way to heal the girl, but ...... Alas, since you're all right, I'll go to the fields to get busy......" Ergouzi shook his head and left.

"Ergouzi, help me carry a basin of water in!"

At this time, Zhuang Lao's voice came from the inner room, Zhao Feng hurriedly replaced Ergouzi, used a wooden basin to receive the hot water originally prepared for him, and then came to the door of the inner room and asked: "Zhuang Lao, Ergouzi is busy, I carried water, can I go in?"

“...... You're carrying hot water, aren't you? Pour it out and get a basin of cold water. ”

Zhao Feng was stunned for a moment, in his impression, the doctor gave the patient a treatment process, if he needed to receive water, almost all of it was hot water, so he subconsciously connected to hot water.

"Okay!"

Zhao Feng replied, and then hurriedly brought hot water into the kitchen.

There is no running water in the village, and the villagers' daily water is collected from a nearby mountain spring and stored in a water tank.

After all, Zhao Feng was also born in the countryside, and Zhuang Lao's house had many similarities with the old house in his hometown, so he naturally found the water tank smoothly.

"Zhuang Lao, I'm in......"

After a reminder, Zhao Feng pressed the wooden basin against the wooden door, and slowly opened it, a strong smell of herbs accompanied by a hot air rushed in, the inner room was dim, although there were two windows in the room, but they were blocked by a heavy black cloth, and Zhuang Lao sat on the edge of the bed, holding a pu fan, looking at the patient on the bed with a solemn face.

"Soak this towel in water, wring it out, and put it on the bedside. Zhuang Lao commanded, and the pu fan in his hand fanned at a certain stable frequency, not in a hurry.

Zhao Feng hurriedly picked up the white towel at the head of the bed, and as soon as he got his hands on it, it was unusually stuffy, but he didn't think much about it, so he quickly soaked it in cold water, rubbed it clean, wrung it out, and folded it.

"Bother you to put a towel on my granddaughter's forehead......"

Zhao Feng listened, held the towel, bent down close to the patient on the bed, as his eyes adapted to the darkness, he finally found the patient's forehead, and after putting the towel away, he noticed that the patient looked like an eight or nine-year-old girl, and his face was very thin, and the eyebrows that were originally slightly frowning were temporarily calmed down after the cold towel was put on the forehead.

Zhao Feng got up, thought for a long time, and asked, "Old Zhuang, I don't know what disease your granddaughter is suffering from?"

"Uremia, diagnosed at birth, is an extremely rare congenital uremia, but it is not the same as ordinary uremia...... The cub's uremia will continue to break out in the environment of light and heat, especially when the sun rises every day, the cub's reaction will be more intense, and she almost ...... several times," Zhuang Lao replied in great pain.

"Why don't you go to the city and be hospitalized? hemodialysis might save her." Zhao Feng listened, his heart was full of unbearable.

"The cub's body is already weak, dialysis hurts her too much, she can't bear it once, all the hospitals have decided that she is not suitable for dialysis, and no hospital dares to accept her, so I can only take her back to the village and use earthwork herbs to relieve her pain every day...... But there is still no clue about the cure...... Can you please help me take care of the cub for a while, and change the towel on her forehead every five minutes, the herbs at home are almost used, I have to go to the nearby mountains to look for them, and I will be back in about two hours. ”

Faced with Zhuang Lao's request, Zhao Feng couldn't refuse.

Just after Zhuang Lao left, Zhao Feng took out his mobile phone, turned it to silent, and set a time of five minutes, he didn't know medical skills, so he could only cautiously follow Zhuang Lao's instructions, accurate time, and change the towel every five minutes.

Half an hour later, Zhao Feng felt that the water had become warm, so he temporarily got up to change the water, and just walked out of the inner room, only to notice that the water in the wooden basin had been pale red, and there was no suppression of the smell of herbs in the inner room, and finally smelled the pungent blood in the water, mixed with a hot and rotten breath.

"The sweat on my forehead alone has such power...... What kind of pain is that kid enduring?" Zhao Feng's heart trembled.

Changed the water and went back to the inner room.

Zhao Feng watched the girl's eyebrows frown up again and again, calming down, as if it was a never-ending cycle of death......

"Alas......"

With a sigh, Zhao Feng had made up his mind.

"Refining snake venom, the second vein and blood vein have been formed, my blood has refined medicinal power, according to the description of the Eight Desolation Martial Veins, this blood medicinal power can turn poison, but to what extent it can be reached, only based on the description of words, it is still unknown. ”

Zhao Feng put his hand in cold water and soaked it for a while, and when his palm was slightly cold, he raised and bit his index finger, and a drop of black blood oozed from the wound, and when the blood vein was formed, the blood in Zhao Feng's body had all turned black.

"It's better to be cautious and try it with a drop of blood first. ”

A drop of cold black blood fell on the girl's bloodless lips and ran along the slit of the lips, and was finally swallowed.

Zhao Feng nervously observed the cub's expression, five minutes passed, there was no sign of frowning, and there was even a slight pursing of the lips, instinctively wanting to ingest the medicinal power that was beneficial to himself.

"Whew, it seems to work...... Since this is the case......" Zhao Feng took out a scalpel from the medicine box on the side, and then half knelt beside the bed, gritted his teeth, cut his left wrist, and controlled the speed of blood overflow, until the wound was handed to the cub's mouth, and then slowly lifted the inhibition.

"Gurgling ......"

From the beginning of passively accepting the medicinal power, the cub later took the initiative to suck black blood, and the stinging sensation in his body that had lasted for eleven years weakened for the first time, and even disappeared completely.

In half an hour, two-thirds of the black blood in Zhao Feng's body was absorbed by the cub, as early as ten minutes ago, he already had a feeling of dizziness, but he still persevered, but fortunately, the sucking sensation gradually disappeared, and the cub stopped ingesting black blood by herself.

Zhao Feng hurriedly suppressed the blood from the wound, but in fact, he was already seriously ischemia, even if he didn't take the initiative to suppress it, there wouldn't be much blood to flow, if it wasn't for the cultivation of skin veins and bloodlines, his physique was different from ordinary people, and he was afraid that he would have passed out long ago.

"I don't know if this can get rid of her uremia, even if it can't, even if it can relieve her pain a little, it's worth ......" Zhao Feng had a sense of accomplishment for the first time, he showed a reluctant smile, stood up with his right hand supporting his knees, the originally gentle dizziness suddenly became stronger, and in an instant, the sky was spinning, his body swayed from side to side, and he could fall to the ground unbalanced at any time!

Zhao Feng held on to the earthen wall, gasping for breath, sweat on his head was like rain, his face was so white that there was no trace of blood, he was even a little reluctant to stand, in order not to have more problems in his body, he could only forcibly speed up the blood flow, as much as possible so that the body would not be in a state of "dry blood" for a long time.

After more than ten minutes, the dizziness subsided, the blood veins operated normally, and new black blood was re-derived to make up for the vacancy in the body, but the recovery speed was not fast, Zhao Feng was still extremely weak, and then there was a strong feeling of hunger and thirst, and his physical condition was simply terrible.

Straightening his waist again, Zhao Feng looked in the direction of the bed, only to find that the girl cub had woken up, and was staring at him with curious eyes at this time.

"Little sister, how do you feel?" Zhao Feng asked with concern.

"Hmm...... It doesn't hurt anymore...... Uncle, who are you? I don't think I've ever seen you...... Where's Grandpa?" the girl didn't speak loudly, but she was able to speak normally and coherently.

"My name is Zhao Feng, and I am a patient of your grandfather. Zhao Feng said with a smile.

"Oh, that's right...... If you are sick, you should take medicine obediently...... Don't be afraid, grandpa's medical skills are good, and he will definitely cure your ......" The girl comforted, listening to her serious and sensible tone, Zhao Feng smiled.

"By the way, my name is Yaya, and grandpa always calls me Ya Cub, but I've grown up......"

At that moment, the door to the inner chamber was pushed open.

Zhuang Lao came back, and as soon as he entered the door, he heard the sound of Yaya communicating with people, and when he stepped forward, he saw that Yaya looked relaxed and had no pain at all, and he was stunned on the spot......
