Perhaps stimulated by the medicinal herbs, after running the Five Poisons Heart Sutra again for a short while, a trace of true qi finally formed in the meridians in Tang Lie's body, although this true qi was so weak that it was almost negligible, but this was also a qualitative change for Tang Lie. Welcome to the reading

This trace of true qi did not make Tang Lie's mood change in the slightest, he would not be happy because of the appearance of this trace of true qi, and Tang Lie knew very well that these Xu true qi did not have much effect on him.

The true qi in the body can only be called internal force when it reaches a certain degree of strength, and the internal force is not really as legendary as it is, it can achieve some other peculiar effect in the air."

If there is only internal force and no external power to guide it, then the internal force can only be regarded as a kind of pranayama body's 'qi', which may be able to achieve physical fitness and make life longer than ordinary people, of course, it is impossible to say that the internal force is deep enough to be immortal.

However, as a martial artist, internal strength and external strength are indispensable. The practice of external skills is not based on one's own essence and blood, no matter what, practicing all external skills will consume one's own essence and blood, and the secret weapon techniques and tricks of the Tang Sect are no exception, and the poison skill is a large consumption.

If you don't practice internal strength, then you can only go to external things to replenish, for example, ingest a lot of food or through medicine to replenish the consumed essence blood and vitality, the more intense the cultivation of external strength, the greater the consumption of essence and blood, in the later stage, only relying on external things to replenish the root is not enough, if you don't cultivate internal strength, then in the end it will only be exhausted and die.

Of course, even if the internal force is deep enough, in the later stage, it also needs the replenishment of external substances to make the consumption of essence and blood proportional to the replenishment, after all, the formation of true qi can be very slow, and it also takes a long time to recover after the internal force is exhausted, which is why the ancients would say: Rich and poor, if you have no money, what do you use to buy food and medicinal materials?

Of course, if you only practice internal strength, if you don't practice external strength, you may not be able to live longer than ordinary people, there is a saying called 'void is not replenished', and the essence and vitality contained in true qi and internal force are no less than ginseng and other great supplements.

It's like the body is a sealed container, and the essence blood and vitality are the yèti in the container, if there are too many yèti and there is nowhere to release them, and they are still increasing, it is easy to think about what the consequences will be in the end. This is why it is said that the solitary yin does not grow, and the solitary yang does not grow.

What's more, only internal strength does not practice external skills, it is impossible to engage in high-intensity battles with others, and the physical method will only hurt oneself before hurting others, so if you want to become a master, internal strength and external strength are indispensable.

For the next two days, Tang Lie came to his rented room every day as soon as Chen Jing went to work to boil the medicinal herbs first, then went to the park to exercise, and then came back to soak in the boiled medicinal herbs after his body reached the limit.

As for practicing external skills, Tang Lie is not in a hurry, with the experience of his previous life, Tang Lie will naturally not have too much trouble practicing external skills, and after his body and internal strength reach a certain level, Tang Lie only needs to practice diligently to make himself proficient again.

School is going to start tomorrow, but fortunately, on this day, Tang Lie feels that his body can barely meet the requirements of washing the marrow.

As for the use of washing the marrow, it is to make yourself stronger. Just like when the baby is still in the mother's body, the meridians of the whole body or the body do not contain a trace of impurities, and even the breath is carried out through the umbilical cord for fetal breathing, and so the impurities are filtered by the placenta, and the baby has always maintained the purest state, and the body will grow the most, which is why the child grows tèbié in infancy.

After the birth of the umbilical cord cut, the baby will lose the placenta to all impurities filter, with the continuous growth of age, the impurities contained in the air and food are filtered directly into the body, irregular work and rest time, excessive wine and other bad habits so that the body meridians are slowly blocked, and the impurities in the body are more and more, so that the body will age, and all kinds of diseases will be added.

Washing the marrow is to wash away the impurities accumulated by the body day after day, so that the body can return to the purity of a baby this time, so that the body can absorb the vitality and strengthen it.

After the true qi in the body reaches a certain level, it can automatically purify the impurities ingested into the body, which is the so-called innate realm, even if it reaches the innate realm, it is impossible to live forever, but the lifespan is much longer than that of ordinary people.

Washing the marrow is simple, but it is not so pleasant, it is to forcibly remove the accumulated impurities from the body, and over time, both muscles and bones contain a lot of impurities, and the severe pain contained in these impurities is not something that ordinary people can bear.

The pain of washing the marrow is like cutting off some inferior bones and muscles, but these inferior bones and muscles are found all over the body, so the pain contained in the marrow washing will not be less than that of Ling Chi in the ten tortures of the Manchu Qing Dynasty.

But there has always been a record of this method of washing the marrow in the Tang Sect, of course, it is impossible for everyone in the Tang Sect to wash the marrow, and the ordinary human root method bears this kind of pain, even if Tang Lie washed the marrow in his last life, he almost broke off because he couldn't stand the pain, because once the marrow washing was carried out, he couldn't stop, even if he fainted in pain, he would immediately wake up again, and the only way to relieve this pain was to die or persist until the marrow washing was completed.

Looking at the bowl of medicinal soup used to wash the marrow that he had boiled on the table and the potion in the wooden basin to assist in washing the marrow, Tang Lie couldn't help but sweat on his forehead when he recalled the pain of washing the marrow in his previous life.

Taking a deep breath, Tang Lie tried his best to calm himself down, and then sealed the house with the sound insulation board prepared in advance, leaving only a breathable hole, otherwise he couldn't help but yell when he would wash the marrow, and it was not good to attract the neighbors next door.

After everything was ready, Tang Lie took off his clothes and sat in the wooden basin, holding the bowl of medicinal soup in his hand and hesitated for a while before gritting his teeth and drinking the medicinal soup.

After drinking the medicinal soup, Tang Lie sat upright in the wooden basin, constantly operating the faint trace of true qi in the meridians according to the Five Poisons Heart Sutra, as the medicinal effect was slowly absorbed, half an hour later, Tang Lie felt bursts of sharp pain from the muscles of his body, just like a few knives constantly cutting off pieces of meat on his body, some impurities in the muscles were slowly removed, and a layer of black dirt appeared on Tang Lie's body surface.

This kind of pain is no longer something that ordinary people can bear, ordinary people are estimated to have fainted in pain and then woken up three times, but Tang Lie gritted his teeth and didn't let out a roar, but the beads of sweat the size of beans appeared on his forehead, but Tang Lie's pain at the moment.

Now he can still hold back and not roar, because Tang Lie knows that the pain has just begun, and now it is only the pain of the muscles, and when the effect of the medicine is fully exerted, the pain will be added juliè, and at that time, it is not only the muscles of the whole body that will have this kind of knife-like pain.

As the effect of the medicine was played, the beads of sweat on Tang Lie's forehead became more and more, and the gums were also bitten out by Tang Lie. After a while, Tang Lie's bones were broken inch by inch, and there were bursts of knife-like pain in his internal organs.

Some people may think that this knife-like pain is nothing, if it is only one or two places, it is really nothing, but now Tang Lie's whole body is like a piece of flesh cut by thousands of knives, and the effect of all this pain will add up is only known to those who have experienced it.

Just like Ling Chi in the Ten Tortures of the Manchu Dynasty, the first knife may not be very painful, but it is difficult to say after cutting off a hundred pieces of meat.

At this time, Tang Lie's pain was worse than Ling Chi's, because his pain was not only muscles, but also bones and internal organs, when this kind of pain that penetrated deep into the bone marrow became more and more juliè, Tang Lie, whose willpower was more than ten times that of ordinary people, could also bear it, and a heart-rending roar came out of Tang Lie's mouth.

Fortunately, Tang Lie sealed the house with a soundproof board in advance, otherwise his roar would probably make many people next door think that the wolf was coming. The pain of washing the marrow was not alleviated by Tang Lie's roar, but became more and more juliè, and the bones and internal organs of the whole body seemed to be shredded inch by inch.

Now every second is a torment for Tang Lie, but he has no choice but to bear it. Tang Lie, whose willpower is as strong as a rock, almost had the idea of suicide, but after thinking of his mother Chen Jing, Tang Lie's willpower became firm again.
