Usu thanked him gratefully.

But as soon as her words fell, Pei Yi jumped up in horror, as if someone had transmitted a message to him.

"Uncle Jiu, I'm sorry, I'm talking nonsense, yes, yes, I'm going to practice sword moves three hundred times."

"What, go to you and practice, don't-"

"Okay, okay, I'm coming."

Pei Yi seemed to have been reprimanded by Pei Jiuzhi, he looked at Wu Su with a little weakness and said goodbye to her.

Usu watched him leave, his gaze falling on him all the time, not looking away.

She thought that the little guy who didn't even dare to pull out baby teeth back then has now grown into such a handsome boy.

It was only at this moment that she truly felt the passage of time.

More than a thousand years should be a long, long time for human beings.

It wasn't until Pei Yi's figure disappeared into the plum blossom forest that Wu Su turned around and prepared to go back to rest.

At the same time, Pei Yi also received an additional punishment from Pei Jiuzhi.

"Practice sword moves three hundred times." He said to Pei Yi in a cold voice.

"N-yes!" Pei Yi was really about to cry this time.

"Uncle Nine, what did I do wrong?"

Pei Jiuzhi stood in the center of the courtyard with his hands in his hands, and the falling plums behind him were fluttering.

He remembered that last night, when he left, Usu quickly closed the courtyard door without looking at him more.

Today, she is good, she has watched Pei Yi for so long.

- It must be Pei Yi's kid, who doesn't know the danger of demons, and talked to her more, which attracted her attention.

In short, punishing Pei Yi is.

Pei Jiuzhi thought about it like this, so he didn't answer Pei Yi's words immediately.

The unlucky little boy climbed to the Sun and Moon Peak with his sword in his arms, barely raised his sore hand, and continued to practice sword moves.

Usu returned to her residence, and she flipped through the books she had retrieved, ready to make up for the knowledge she had been isolated from the world for more than a thousand years.

Over the years, Xianzhou has indeed undergone a lot of changes, and this change comes from the arrival of Pei Jiuzhi.

He has done a lot of things, so that the average cultivation of the monks of Xianzhou has increased a lot, and the development of Xianzhou has become more and more prosperous.

According to the thin bloodline of the Pei family, the mortal world should have been suppressed and sealed hundreds of years after he came to Xianzhou, which caused the seal of the demon domain to be loosened because there was no Pei family.

Then, the innocent mortal world will be occupied by the demons of the demon realm, and the mortals will struggle to survive in a corner of the mortal world, waiting for the salvation of the monks of Xianzhou.

This is a terrible end for mortals.

But Pei Jiuzhi did something quite crazy, he cultivated the most difficult forbidden technique in Xianzhou to master, Tong Zeyin.

This Tongze seal can pass on the cultivation of his body to others.

If a mortal person obtains a trace of his cultivation, he will be able to obtain the longevity of eternal life and the ability to cultivate.

He placed a total of three Tongze seals, one of which was placed on the body of Pei Huasheng, the current emperor of Yundu.

Because she is the best emperor who has ever managed the cloud capital, even more suitable than her father Pei Chu.

It stands to reason that as long as Pei Huashang is left as a descendant of the Pei family, the seal of this demon domain can be guaranteed to be immortal.

But he gave Pei Yi another Tongze seal, and Pei Yi had a faint spiritual root because of this, and he was able to reluctantly cultivate.

The third Tongze seal, he gave it to the land of Xianzhou.

Since then, this vast territory has been tied to his life, and as long as he is alive, he can protect the eternal peace of this immortal continent.

Every hundred years, at the source of the Luo River in Xianzhou, a mysterious spring will appear.

A large amount of pure energy for cultivation would gush out from this spiritual spring.

- This is also the effect of Pei Jiuzhi's Tongze seal.

If a monk can pass the test, he will be able to absorb the spiritual spring and cultivate, and his cultivation will be a thousand miles in a day.

Therefore, every hundred years, the monks of Xianzhou would chase the power of that spiritual spring.

The three Tongze seals under Pei Jiuzhi, one protects the immortality of the world, and the other protects the eternal peace of Xianzhou.

There is another one, which seems to be redundant.

According to Pei Yi's identity and fate, sooner or later he would sacrifice his life and blood, but Pei Jiuzhi left him behind.

No one knows what Pei Jiuzhi's intention was in leaving Pei Yi.

Only Wu Su raised her finger, and she gently stroked the string of words describing Pei Jiuzhi's exploits.

She knew why.

The reason for this is simply that many years ago, he gave her a promise.

Unexpectedly, he remembered it now.

Usu sighed softly, and she closed the page in her hand, her desire to leave intensified.

The next few days went on as usual.

The Immortal Continent is vast, and all the creatures here have a long lifespan.

Therefore, in these few days, Usu hardly found any lost life to absorb the yin and yang energy.

Without yin and yang energy, she would not be able to improve her strength, and the task of killing Li Xuan became more difficult than ascending to the sky.

Usu was in an awkward position.

When she lay down to sleep at night, she could always think of the conversation Xie Youming had with her.

"What if ......," Usu asked Xie Youming in the lantern cage, "What if I don't have enough yin and yang energy to improve my strength?" ”

Xie Youming smiled: "Won't you kill people?" ”

"Killing Li Sui is killing, killing more monks is also killing, I hope that all the monks in the world will die cleanly."

He said so frantically that he was soon retracted from his body by the question.

Wen Yuan looked at Wu Su helplessly, scolded Xie Youming, and said, "He's talking nonsense." ”

There was no progress on the mission for a long time, and Usu became a little anxious.

This fairy continent is like a paradise, and she really can't absorb yin and yang energy.

Usu was so worried that one day, she sensed the signs of a dead life around her.

Pei Jiuzhi actually didn't restrict her movements too much, so Wu Su walked out of the Sun Moon Sky and quickly flew in that direction.

There was a small sect on the east side of Xianzhou, and there were a few monks coming and going near the mountain gate.

Usu passed through the prohibition of this small sect and walked straight in the direction of the lost life.

The terrain in this sect is a bit complicated, and Usu has to make several detours of mountain roads before he gets close to the target.

In the meantime, she almost collided with an oncoming man in gray.

Fortunately, she turned sideways in time and did not expose herself.

She was slightly stunned, thinking that this person was an ordinary monk in the sect, so she didn't think much about it and continued to do her own thing.

Usu was in a hurry to absorb the yin and yang energy, so he ran there.

In the main hall of the sect, there was a dead silence.

It wasn't until Usu got closer here that she realized that it turned out to be ...... Those who died here were monks.

Blood spilled down the white staircase, and Usu lifted her skirt and stood on tiptoe, cautiously approaching the corpses.

But even though she was so careful, she still left a series of faint footprints on top of the bloodstain.

She saw that some of the dead monks were staring wide-eyed, as if they were unwilling.

Usu crouched down and tenderly closed their eyes, which were not yet blind.

Usu only felt the yin and yang energy that filled the entire hall, and they were waiting for her to grab them.

But—she didn't feel the desires of these departed souls, their consciousness as if it had been wiped out by some force before they died.

In the face of wishless souls, Usu can directly absorb the yin and yang energy generated by their death

— and she doesn't have to pay any labor or price.

She suddenly realized something, and stepped back in some horror.

But the yin and yang energy that spread throughout the hall had swept towards her.

Usu didn't dare to absorb such a helpless power, and hurriedly dodged.

At this time, her old problem was committed again, and at this moment, her eyes were darkened, and she could not see anything.

Coincidentally, she lost her vision today.

Usu's feet stepped on the white jade ground dripping with blood, and she lost her vision and had difficulty maintaining her balance, so she fell to the ground.

At the same time, a large amount of yin and yang energy also burrowed into her body and was completely absorbed by her.

Usu sat there a little bewildered, and she felt her palms wet and sticky.

A thick bloody breath filled her nose, and she tried to drive the yin and yang energy she had accidentally absorbed out of her body.

But these energies have merged with her essence and strengthened her.

Usu's brows tightened, she knew that if she stayed here, she wouldn't be able to explain it clearly.

She got up from the ground and was about to hurry away, the golden locks that bound her ankles had pulled her body.

Your Highness! Usu was a little surprised, she thought, he should have known that something had happened here.

Usu thought that if he could make him mistakenly believe that he had killed the monk, he should kill himself.

At that time, she would be able to leave Xianzhou with the help of her body that had dissipated due to her huge fatal injury.

Usu didn't care if others misunderstood her.
