Last year, Sun Yuenlong was hit by Zhang Xuanyi's mixed yuan finger, and he thought that as long as he breathed for a period of time, his skills could be restored. But it took him a whole month, but he still couldn't return to the half-step innate realm, let alone see the colorful membrane.

Sun Yuanlang is a genius, so he can naturally figure out that he fell for Zhang Xuanyi's poisonous scheme. At that time, it seemed that he was only punishing him slightly, and he just wanted to establish his authority, but in fact, he harbored evil intentions, leaving a wisp of mixed yuan true qi beyond Sun Yuanlang's realm in his meridians, completely blocking the door to the innate one.

If he didn't refine that wisp of true qi, or force it out of his body, Sun Yuanlang would not be able to return to the half-step innate realm in this life. This is absolutely unacceptable to anyone who has realized the innate mystery of half a step. What's more, Sun Yuanlang, who is arrogant and has always been dissatisfied with Zhang Xuanyi?

After trying all kinds of methods to no avail, Sun Yuen Long finally made up his mind to close the retreat. He had people build a secret room made of pig iron in the middle of the lake, and prepared to lock himself in it.

The space of the iron room is very narrow, only Zhang Xu can see the square, it is impermeable, there is no light inside, ordinary people are locked in, and it will not take a few days to go crazy. But those who can achieve the Great Grandmaster of the Heavenly Rank are all people with outstanding perseverance, and Sun Yuen Long is even more comparable to the Extraordinary Great Grandmaster. He only brought enough dry food and water, and then asked people to lock the door from the outside, swearing not to return to the half-step innate, and never to step out of the iron room!

Sun Yuanlang is a genius in the sky, and he uses this seemingly nonsense method not to break or stand, so he naturally has his reason in it.

Whether it is the Tao of the Heavenly Master or the Tao of Taiping, as long as it is Taoist practice, it pays attention to a 'return to the baby', in short, it is to return to the state of the baby. This is because the state of the baby when it is in its mother's womb is the innate state that a practitioner dreams of but cannot see!

Taoists believe that if people can gather their essence and soften like a fetus, so that the essence of the spirit does not dissipate, then they can obtain an immortal body like the eternal avenue - the so-called innate realm!

But once a person comes into the world, it is impossible to return to the state of a fetus. How do acquired people set foot in the innate realm? This is also the biggest problem that has plagued practitioners since ancient times.

Sun Yuanlang thought of a way to cast an iron chamber at the bottom of the lake and imprison himself in it to simulate the state of the fetus. Being in the iron room, just like the fetus in the mother's body, unable to see, unable to leave the house, and the surroundings return to chaos. In it, the concept of time and space disappears, and so does all the distractions of the world, and all he can focus on is himself.

In such an environment, the five senses have lost their function, but the sensations in the body have been magnified countless times, and he can clearly feel that his blood is circulating in the body, and the true yuan is running in the meridians. The whole body, the limbs, the eight veins, and the twelve meridians are all as good as the patterns in the palm, and the feeling is clear.

In this iron room, he finally captured the wisp of mixed yuan true qi hidden in his body for the first time. After completing the most difficult step, there were more choices in front of Sun Yuanlang, he could either choose to force him out of his body and completely restore his realm, or he could choose to refine it slowly and use the Mixed Yuan True Qi as a guide to improve his realm.

Of course, the former is time-consuming and risk-free. The latter is time-consuming and risky, but once successful, the benefits are also huge!

Sun Yuanlang chose the latter without suspense, but he didn't expect that this road would be more difficult than he expected. He had been working hard in the iron chamber for two whole months, and he still couldn't refine that abominable wisp of mixed yuan true qi!

Just when Sun Yuanlang was about to be tormented by the darkness, loneliness, depression, and frustration day after day, and finally couldn't help but get out of the customs, he took the craftsman to pour the molten iron on the door of the iron room, trying to seal Sun Yuanlang alive in the iron room.

Sun Yuanlang had no hope of going out at all, and in despair, he threw away his last scruples and truly entered the realm of death and rebirth!

He no longer had the luxury of using his true qi to assimilate Zhang Xuanyi's mixed yuan true qi, and was ready to pour out all the true qi in his body instead, leaving only that wisp of mixed yuan true qi swimming in his body. Sun Yuanlang's idea at this time is very simple, as long as he only has the Mixed Yuan True Qi in his body, then the Mixed Yuan True Qi is his own True Qi! There is also no alien true qi in the body, so naturally there is no trouble for anyone to make trouble for anyone, and for anyone to refine whom!

This method is simple to say, but for the great grandmaster who has countless true qi at every moment, and it is bred from the sea of dantian qi, it is tantamount to an idiot's dream. Even Sun Yuanlang, who had mastered his true qi to the pinnacle, couldn't do it at first. But he was already in the Jedi, and he didn't think about it, but just condensed all his thoughts on this one thing, day after day, and the water dropped.

Finally, seventy-seven and forty-nine days later, as Sun Yuanlong's body became weaker and weaker, the true qi that grew in the dantian was less than one-tenth of the beginning. On the contrary, in this arduous tempering day after day, his spirit entered the infant realm of joylessness, worry-free, hopelessness and thoughtlessness. In the interim, Sun Yuanlang was finally able to do whatever he wanted, expelling all his true qi from his body.

At this time, he finally reached the state where the dantian was empty, and there was only a wisp in the meridians. That wisp was the mixed yuan true qi that Zhang Xuanyi punched into his body. This wisp of mixed Yuan True Qi was originally a spy mixed with his own huge True Qi, but at this moment, he became the master of the meridians in his body. True Qi has no thinking, so he naturally regarded Sun Yuanlang's body as his own origin, and began to circulate in his body as he wished!

Every Sunday after circulation, the mixed yuan true qi in Sun Yuanlang's body will be one point stronger! Sun Yuanlang was ecstatic to find that his dantian began to breed pure mixed yuan true qi, but the original ordinary true qi was produced less and less......

It was another seventy-seven forty-nine days, and Sun Yuanlang was already able to completely control the mixed yuan true qi in his body, and completely suppressed the breeding of ordinary true qi. At this time, he was finally full of confidence, as long as time passed, there could only be one kind of true qi in his dantian, the mixed yuan true qi, and no other impurities would be breeded!

At that time, it will be the time to ask for yourself!

Zhang Xuan never dreamed that he harbored a finger of evil, but he let himself be blessed by misfortune, and finally touched the path to the sky!

Although I don't know where Zhang Xuanyi has been, I guess that guy is also struggling to climb on the same road, right?

The so-called people are not as good as heaven, and there is probably nothing more than this!

However, Sun Yuanlong's excitement did not last long, and he was poured cold water by the cruel reality.

Suddenly, he found himself without food and water......
