If these words are said by the old doctor in his seventies and eighties, it is nothing, but this kid is still so young, and he actually has such knowledge, what a demon!

After listening to Zhang Yu's words, the old men couldn't help but look at Old Man Cai, they never knew that Old Man Cai had injuries on his body.

"Could it be that this time...... Wounded?" Yang Lao suddenly remembered something, he couldn't help asking, many years ago, they were as young as Zhang Yu, spilling blood for the revolutionary cause, that time they went to meet an informant and provide information about the enemy, that knew that they were ambushed by the enemy, and Old Man Cai led the enemy away alone in order to cover them. Yang Lao thought he was dead and regretted it, and later he was arranged to work as a political worker, and he didn't meet again until a few years ago, and Old Man Cai didn't say it, he didn't know that Old Man Cai was injured at all.

"Hehe, then do you have a way to treat it?" After the old man Cai nodded slightly, he turned his head and asked Zhang Yu, his expression did not start with contempt, and became more cautious.

The old man was in an uproar, this sentence showed that Old Man Cai admitted that Zhang Yu was right, Old Man Tian, who scolded Zhang Yu just now, was a little embarrassed, but Wen Ya became excited, she looked at Zhang Yu proudly, so focused.

"Can I take a look at the wound?" Zhang Yu did not answer Old Man Cai's words.

"Yes!" Old man Cai quickly took off his shirt and exposed his arms.

"Hmm!" Seeing the wound on Old Man Cai's arm, Wen Ya covered it and screamed, as if a large piece of meat had been dug away by a knife, revealing a hole where muscles were tangled, hideous and terrifying.

"This ......" The old men looked at the hole in his arm in surprise, and they instantly recognized that it was bitten by the 38 big cover.

"Old guy, why didn't you say it earlier?" said Yang Lao excitedly.

"Did it work? I saw so many doctors, but it didn't work. Old man Cai rolled his eyes and said.

"It must hurt, right?" asked Wen Ya, biting her lip.

"Actually, it's nothing, it's just that it's raining and it's a little ...... in winter," Old Man Cai said with a smile.

"How is it? Can he be treated like this?" Yang Lao turned his head and rubbed his hands and asked Zhang Yu anxiously.

"Yes, what's the way, he's so pitiful!" Zhang Yu didn't speak, he felt that someone had pulled his sleeves, turned his head and found Wen Ya whispering, Zhang Yu smiled and patted the back of her hand, turned around and stared at Old Man Cai's arm.

Yin-Yang Pupil Technique!

Zhang Yu used the pupil technique again, and at this time, Old Man Cai also stared at Zhang Yu, and suddenly he found that Zhang Yu's momentum had changed, especially those bright eyes, which suddenly became deep, like the starry sky in the universe. However, this feeling disappeared in a flash, which made Old Man Cai's expression weird, and he intuitively felt that the kid in front of him was not as simple as it appeared.

Muscle atrophy and nerve cells are hit hard......

Zhang Yu muttered while watching, but these are the microscopic theories of Western medicine, and the most commonly used by him is the macroscopic theory of traditional Chinese medicine......

He suddenly discovered that the purpose of treating ghosts is to repair the soul body, and the life of a doctor repairs the body, and the two are complementary to each other.

It was as if a new door had opened in front of him, and he became excited.

"I can try, no matter how bad it is, it can relieve the pain. Zhang Yu nodded and said, when Zhang Yu said this, Yang Lao breathed a sigh of relief, in his opinion, Zhang Yu said to try, the grasp is a bit big.

"Really?" Old man Cai became excited, this arm usually hurts faintly, and it is even more unbearable in rainy days and winters. It's not bad if it can relieve the pain, after all, it's not a way to endure it, he has never taken painkillers, and if he eats too much, he will die faster.

Old man Cai saw some dead comrades-in-arms, all of whom took a lot of painkillers, and died early.

"Of course it's true. Wen Ya next to her rolled her lovely eyes and said, I dare to question our family Zhang Yu, hum!

"This little girl is very sharp-toothed, the kid is so blessed!" Cai Lao smiled, patted Zhang Yu's shoulder and said. It was subconscious to pat the shoulder, but after patting, Cai Lao was surprised again, his hand strength was known, ordinary soldiers couldn't stand it, he couldn't imagine that the handsome kid in front of him was like no one, he couldn't help but be more interested in Zhang Yu.

"Excuse me, put your arms on your hips. Zhang Yu admonished, Old Man Cai nodded and did so. He watched curiously as Zhang Yu took out a needle belt, and then pulled out a few snake head needles from it, the snake head was lifelike, with different shapes, and it was not ordinary at first glance.

Zhang Yu thought slightly, and the spirit snake needle in his hand kept piercing into the acupuncture points of Old Man Cai's arm, the back branch, and the patio......

Seeing Zhang Yu's skillful technique, several old men were dumbfounded, they have become good doctors after a long illness, these old men have more or less physical problems, plus they are old, seeing a doctor and taking medicine is like a common thing, and acupuncture is not less.

They have seen such a fast speed of acupuncture recognition, even some old acupuncture doctors, they dare not learn Zhang Yu, for fear of piercing the wrong position, resulting in a serious condition. They didn't know that Zhang Yu's physical fitness was more than ten times that of ordinary people, coupled with his super memory, he would have this performance.

When the spirit snake needle pierced into his arm, Zhang Yu used the Heavenly Sacrifice Needle, one of the nine needles of Taiyi, to guide a large amount of yin or yang qi at the moment of piercing, and used the needle to control the frequency of yang or yin qi entering the acupuncture points of the human body.

"Do you feel anything?" asked a few old men next to him anxiously.

"It seems to be a little hot and a little cold......," Old Man Cai said hesitantly, he felt that the silver needles piercing his arm were hot or cold, this contradictory feeling was too strange.

"Is it hot or cold?" asked Elder Yang curiously.

"It's hot, wow, it's hot!" suddenly Old Man Cai shouted, his expression was extremely exaggerated, startling everyone.

"Bear with me!" Zhang Yu said with a serious expression, as if he was an order, Old Man Cai didn't move, he forcibly endured the burning of his arm, and the naked eye could see that the skin and flesh were red.

"Could it be to expel the yin and cold in Old Man Cai's arm?" Yang Lao guessed, Zhang Yu nodded slightly, it is true, according to the flow of yang energy, he can feel that after the yang energy enters the body, it fuses with the yin and cold qi in the cells of his arm, and after the yin and cold qi is expelled, the yin qi in the silver needle will fuse the excess yang qi to achieve balance.

Easier said than done, Zhang Yu must always control the amount and frequency of yin and yang qi to prevent excess.

Due to excessive concentration, dense sweat soon appeared on his forehead, and Wen Ya wiped it for him with a handkerchief in distress.

"Whew, okay, that's all for today, once a day in the future, it's about the same for a week at most. Half an hour later, Zhang Yu breathed a sigh of relief, twisted out all the silver needles, sterilized them, and put them away.

Old man Cai was still flustered at this time, he felt as if his arm was soaked in warm water, it was extremely comfortable, after so many years, he finally breathed a sigh of relief. The cold feeling at the wound was also much less, and he stood up and moved his arms, making various movements.

"How's it going?" the old man asked anxiously.

"It's much better, and my arm doesn't hurt anymore, boy, the craftsmanship is not bad. Old man Cai said with a smile, he was really satisfied with Zhang Yu.

"Hey, don't look at who I'm recommending. Looking at the surprised appearance of a group of old men, Yang Lao said proudly.
