On a floating boulder in Wujiaxu, Tong Yan was sitting cross-legged. The boulder was huge, like a small mountain. The boulder is smooth and flat, carved with dense strange charms, which shows that this place is not as simple as imagined.

There was a person standing in front of Tong Yan, this person was not a bystander, it was the ancestor of the Wu family.

The old ancestor's expression was a little serious and a little dignified, he glanced at Tong Yan, and then paced back and forth behind his hands. As he walked slowly, he said, "Grandson, there is really not much time left for you, only seven hundred and forty-nine days in total. In these forty-nine days, if you still can't reshape the two veins of yin and yang through your own efforts, I'm afraid that it will be difficult for you to cultivate my Wu family exercises in the future. So, you can't leave this place for a moment during this time. This is the place where I realized the Tao back then, and I hope you can concentrate on it, comprehend it with your heart, and don't let me down! Remember? ”

Hearing this, Tong Yan hurriedly said solemnly: "Yes, my grandson must redouble his efforts to live up to the expectations of his ancestors!" ”

The old ancestor nodded, and then sighed lightly: "Child, everything is predestined. If you destroy the dantian yourself, you can only repair it by yourself, and I can't blame you more. It's man-made, you can do it yourself! The day of retreat begins today. Every day if you are tired and hungry, take a Guben Pill that I have given you, and it will help you survive these forty-nine days. I still have some things to deal with, I may leave the Wu family's old mansion for a few days, during this time, no one will come to disturb you, work hard! With that, his figure flashed, and he flew off into the distance.

Looking at the back of the departing ancestor, Tong Yan took a deep breath, then put his hands on his knees, closed his eyes tightly, and began the arduous day of retreat.

However, it was somewhat surprising that he usually wears a bracelet on his wrist, and that bracelet was changed by Xiao Hei. But today, the bracelet is gone, what is going on?

In fact, his bracelet is not missing today, but has disappeared since before he was taken out of the beast prison by his ancestors.

In the emergency situation at that time, in order to prevent Han Yuling from continuing to release cold qi, Tong Yan called Xiao Hei with his mind again and again. Finally, he succeeded.

Xiao Hei opened his eyes under his continuous shouting, but this was also reluctantly. Xiao Hei, who woke up, stopped Han Yuling in time, but it was too seriously injured after all. Even if it can't die, all of its cultivation will be destroyed, and it will fall into a slumber for decades or even centuries.

Han Yuling couldn't bear to watch Xiao Hei fall into an endless sleep, so he made a request to Tong Yan, hoping that Tong Yan could cancel the master-servant contract between him and Xiao Hei. As long as the contract between Tong Yan and Xiao Hei is dissolved, Han Yuling can truly become one with Xiao Hei, and when the time comes, Han Yuling can also share the aura in his body with Xiao Hei, and the two of them will no longer be separated.

But how can the master-servant contract be dissolved if it is dissolved? The conclusion of the contract is like the seal of God, and if you want to cancel it, it means going against the sky, and if you forcibly terminate it, you will inevitably be punished by heaven.

But Tong Yan finally agreed, because the little gang had helped him too many times and saved him too many times. He really couldn't watch Xiao Hei fall into a deep sleep, let alone ignore the fact that his thousand-year-old cultivation was ruined.

In order for Xiao Hei to live well, and in order to fulfill the relationship between him and Han Yuling, Tong Yan unilaterally terminated the master-servant contract.

At the same time, damnation came. Although the Heavenly Punishment did not take his life, his dantian was completely shattered because of this, and even if the meridians were restored in the future, he would no longer be able to ask the immortals.

Tong Yan didn't tell Han Yuling about this, but watched it leave the place with Xiao Hei. It wasn't until they left that Tong Yan couldn't hold on any longer, so he lay down on the cold ice and fell asleep.

Later, the old ancestor entered the prison of the fierce beast and brought him out.

This is why the old ancestor is full of solemnity, and this is why the old ancestor sighs again and again.

The ancestor thought that Tong Yan could inherit his mantle, but at this moment, Tong Yan was completely reduced to a wasted person, even if he had washed the marrow and cut off the bones, it would be difficult for Tong Yan to practice the Wu family exercises. He even said that he couldn't practice any exercises.

But the ancestor was still unwilling to give up Tong Yan like this, so he brought Tong Yan to the "Heavenly Stone" where he had retreated and enlightened. But whether he can recreate the dantian and whether he can successfully reshape the yin and yang veins he said depends on the creation of Tong Yan.

For this, why don't Tong Yan know? But he has no regrets, and he is very calm. He felt that the current situation was not too bad, at least he was still alive, at least he could still bounce like a normal person. Over the years, he has experienced too many hardships and hardships, and he has grown a lot in the grinding again and again.

He always believed that as long as he didn't give up, nothing could break him. This is true now, and it will continue to be so.

Thus began the 7749-day retreat, and although it was likely to end up in vain, he was still trying.

After being washed and cut by Qiqi, Tong Yan can absorb the qi of the surrounding heaven and earth more easily, and his senses around him have also been greatly improved.

But it's a pity that the meridians in his body are all broken, and although he successfully introduces the qi of heaven and earth into his body, he can't swim in his body. And the so-called cultivation is actually to use the qi of heaven and earth to complete the baptism of oneself. Through the introduction of qi into the body again and again, circulating around the body, and finally closing in the dantian, it becomes true qi.

The cultivation exercises taught by the ancestors are very different from the common cultivation exercises, normally speaking, the human body has the eight veins of the strange meridians, which draw qi into the body, that is, mainly from these eight meridians to complete the cycle of Zhou Tian. However, what the ancestors taught is not the eight veins of the Qi Sutra, but the two veins of yin and yang.

There is a saying, if you don't break it, you can't stand it, and then you stand after it's broken!

The cultivation method taught by the ancestors is such an alternative. In order to practice this exercise, the practitioner must suffer from having his meridians interrupted in the first place. The eight veins of the Qi Jing were all interrupted, and finally they were connected to each other and recombined, forming the two veins of yin and yang.

These two veins of yin and yang are actually very much like the two yin and yang fish in the Taiji diagram, the two seem to be opposites, but in fact they have the same root.

The ancestors called this kind of cultivation technique the yin and yang formula, which was created by Wu Bufan, the ancestor of the Wu family. If you can cultivate the yin and yang formula to the extreme, and then cooperate with the Wu family to attack the supernatural powers, you will be proud of the world and invincible.

But even if he was a supreme master like the Old Ancestor, he had only only cultivated to the seventh layer of this Yin and Yang Technique. There are a total of nine levels of realm, and if you can cultivate to perfection, I am afraid that you will not be able to give in to the real immortals.

Of course, Tong Yan hopes that one day he can cultivate the Yin and Yang Technique to the top level, but now, he can't even construct the two veins of Yin and Yang at the beginning, which is really helpless.

And just when Tong Yan was concentrating on retreat, there was already a storm surging on the rivers and lakes, and a big conspiracy was going on little by little......
