Fortunately, it was still early before the concert began, and Yu Yuan was about to turn around and go back to change his clothes, but he was stopped by a high school student of the same age as him.

At first, the man did not embarrass Yu Yuan, but asked him about the whereabouts of Lin Yun and Lei Jie, but the other party's tone of contempt aroused Yu Yuan's vigilance.

However, when Yu Yuan asked the other party about the purpose of looking for Lin Yun and Lei Jie, the other party did not shy away from it, and directly explained that he was going to trouble the Tianlong High School basketball team, and when he learned that they would also come to the concert, he waited here in advance.

As soon as the two sides disagreed, Yu Yuan started with the man, but unexpectedly, the person's cultivation was far above Yu Yuan, and after a while, Yu Yuan was beaten to a blue nose and swollen face, and he had to miss the concert.

After listening to Yu Yuan's narration, Lei Jie took the lead in anger and said: "Damn, it depends on the owner to beat the dog!" Tell Lao Tzu, what does that guy look like, I'll go to Nanshan High School to settle accounts with him after school! ”

In the face of Lei Jie's extremely inappropriate metaphor, Yu Yuan really wanted to cry without tears, and he didn't know whether to answer his question or not, so he just peeked at Lin Yun on the side.

Lin Yun was silent for a while, not rushing to show his attitude, but reached out and grabbed Yu Yuan's wrist.

Yu Yuan was startled at first, but when he found out that Lin Yun was taking his pulse, he calmed down.

According to Yu Yuan's understanding of his body, although this time is a bit embarrassing, basically he will not die if he does not die, but most of the injuries he suffered are some flesh wounds, as long as he cultivates for a period of time, he can heal on his own.

And when Yu Yuan saw the expression on Lin Yun's face and began to become more and more gloomy, his heart also beat a drum, could it be that with a few simple punches and kicks, he could hurt his muscles and bones?

After about two minutes, Lin Yun let go of Yu Yuan's wrist and said in a solemn tone: "Your injuries are very serious, if you don't deal with them in time, it may cause damage to your body in the future." ”

Considering the presence of Lei Jie and Wang Ye, what Lin Yun said was more vague, in fact, Yu Yuan hurt not only his muscles and bones, but also his dantian qi!

According to the results of Lin Yun's pulse, Yu Yuan's dantian qi sea had a secret injury, which was usually difficult to detect, and it had no effect on his qi circulation.

However, if it is allowed to develop, it will inevitably form a permanent internal injury, and once Yu Yuan excessively urges his breath in the future, it will cause a devastating blow to his dantian qi sea, and his cultivation will be completely useless, and it will be difficult to recover.

When Yu Yuan saw Lin Yun's grim expression, he knew that it must be an injury in his body, which exceeded his expectations.

Just when the bell rang for self-study in the morning, Yu Yuan casually found an excuse to be unwell and asked Lin Yun to accompany him to the school infirmary.

Instead of going to the infirmary, the two of them found a remote corner near the library, where people didn't often come in the morning, just right for them to heal.

When he heard Lin Yun's detailed description of his injuries again, Yu Yuan's face suddenly turned pale, he didn't expect that guy to be so ruthless, this was obviously to cut the grass and eradicate the roots!

Fortunately, Lin Yun found it early, and from now on, it will not be too serious to treat it in time.

In response to Yu Yuan's injury, Lin Yun decided to use his internal breath to protect his dantian qi sea, and then use acupuncture to open up his Guan Yuan, Qi Hai, Shenque, Mingmen and other acupuncture points, and guide the qi and blood that were stuck in it.

The decision has been made, Lin Yun repeatedly instructed Yu Yuan to be distracted, every step he takes, if he has distracting thoughts, or acts recklessly without authorization, interfering with the process of treatment, then not only will his cultivation be wasted, but he may not be able to save his life.

Yu Yuan nodded again and again and said yes, his life is his own, and he also knows that he can't come nonsense, everything is subject to Lin Yun's arrangement.

According to the original plan, Lin Yun and Yu Yuan sat cross-legged face to face, their palms against each other, and a breath was released from Lin Yun's palm, and soon swam into Yu Yuan's body, forming a tight protective layer around his dantian qi sea.

Subsequently, Lin Yun's left hand remained still, and his right hand applied needles, and pricked six needles in a row on Yu Yuan's bare upper body, all of which were within the range of the dantian under the umbilicus in his abdomen and under his back and waist.

I saw Lin Yun follow Yu Yuan's breathing rate, constantly twisting the golden needle in his hand, exhaling the needle, inhaling the golden needle, the angle is large, the force is heavy, the frequency is fast, the time is long, basically based on lifting, it is a typical acupuncture laxative method.

Gradually, the stagnant qi and blood in Yu Yuan's dantian were gradually expelled from the body under the twisting of Lin Yun's needle, and drops of dark black blood seeped out from between the skin and the golden needle, and a fishy smell filled the air.

Originally, all of this was going smoothly, and in about half an hour, Lin Yun would be able to expel the hidden danger of Yu Yuan's dantian qi sea.

But at this time, Lin Yun suddenly found that something was wrong.

In addition to this internal injury in Yu Yuan's body, there was also a trace of residual poison that even Lin Yun hadn't noticed before, lurking in the bruise, hidden extremely cleverly.

If the internal injury is not detected for a long time, the toxicity in the blood will only attack slowly, gradually eating away at Yu Yuan's body at a speed that is not easy to be detected.

But at this moment, Lin Yun used acupuncture to heal his wounds, and while expelling that mass of stagnant qi and blood, it also stimulated its toxicity, causing the residual poison to spread rapidly, covering the entire dantian qi sea in an instant.

Sensing this scene, the cold sweat on Lin Yun's forehead fell, and then looked at Yu Yuan, his face, which was quite peaceful just now, became hideous and terrifying at this time, and a black mist shrouded his face, making it almost impossible to distinguish his facial features.

Lin Yun was shocked, he didn't expect the other party to be so vicious and vicious, and he actually made a double poison to Yu Yuan, for the sake of today's plan, it will no longer work to use the original plan, if you want to save Yu Yuan's life, you can only find another way!

Lin Yun knew in his heart that if he delayed for one more second at this time, the toxicity would spread a little more, and the only way at present was to force it out of Yu Yuan's body before the toxicity exceeded the dantian qi sea!

So Lin Yun immediately made a decision, took out a golden needle from the needle box again, accurately pierced it into Yu Yuan's middle acupoint, and used his own strong breath to open up a middle dantian for him here.

After that, Lin Yun used all his strength to keep twisting the needle up and down, extracting the toxicity in the Qi Sea of Yu Yuan Dantian upward, and introducing the lower dantian at the lower abdomen to the middle dantian at the chest......

Seeing that the toxicity had moved upward, Lin Yun made persistent efforts and used two golden needles to pierce the Yintang acupoint between Yu Yuan's eyebrows and the Baihui acupoint between the two ears on the top of his head.

After that, Lin Yun introduced the toxicity accumulated in the middle dantian into the upper dantian, and then through the cultivation of the human body itself, he exhaled the aura of heaven and earth, forcing them to leave nothing behind, and emitted from the top of his head into the air.

This process seems to be cumbersome, but in fact it is the same as the physiological cycle of the human body, just like in the hot summer, you will see some people with steam coming out of the top of their heads, which belongs to the normal metabolism of human meridians.

The difference is that Lin Yun played a role in adding fuel to the fire.

With Lin Yun's help, Yu Yuan not only cleared the residual poison in his body, but also laid a solid foundation for his future internal strength growth, which Lin Yun had not thought of before.

The healing process was completed, and Lin Yun also left himself in Yu Yuan's body, protecting the internal breath of his dantian qi sea, and slowly absorbed it back.

When Yu Yuan slowly opened his eyes, he felt that his eyes suddenly opened up, his range of vision seemed to be much farther than in the past, and his hearing was more keen, which made him ecstatic, he didn't know what exercises Lin Yun used to enhance his physique.

Lin Yun knew in his heart that this was the benefit of Yu Yuan to open up the upper dantian.

The so-called essence, qi, and spirit are actually contained in the lower, middle, and upper three dantians of the human body.

Before the development of the upper dantian and the middle dantian, most of the martial arts practitioners were intent on guarding the lower dantian, focusing on refining the essence, and the internal strength qi refined could only be gathered in a small space, let alone rising to the stage of refining the qi and returning the spirit.

And Lin Yunren helped Yu Yuan expand the upper and middle dantians, so that his "qi" and "god" have room for concealment, which is like being reborn for his internal cultivation, and the future is limitless.

In fact, this is similar to the situation when Lin Yun first cultivated, except that he has now reached the stage of refining the gods and returning to the void, and there is no longer the division of the dantian qi sea in his body, and there is no need to deliberately cultivate internal strength, and he has almost reached the realm of returning to nature.

Although Yu Yuan still has a long way to go on the road of cultivating internal strength, this small change is enough for him to benefit a lot.

The most direct benefit is that after the upper dantian has been expanded, the space for Yu Yuan to contain "gods" has opened up a lot, and the sensory ability of the body has also been greatly improved.

Seeing that Yu Yuan was like a child, constantly examining his body, Lin Yun just smiled and said nothing, talking too much about the cultivation of internal strength is not good, let him ponder it slowly, it will be more conducive to the steady improvement of cultivation.

Of course, Lin Yun would not tell Yu Yuan that due to his momentary negligence, he almost lost his life, but fortunately, in the end, the desperate experiment was successful, so that he was blessed by misfortune......

After healing Yu Yuan's internal injuries, Lin Yun's thoughts returned to the question just now: "What is the origin of the person who injured you?" ”

Yu Yuan was stunned, obviously reluctant to recall that embarrassing experience, but for the sake of Lin Yun just saving himself, he still did his best to depict the characteristics of that person in detail.

According to Yu Yuan, it was a high school boy about the same age as him.
