He became the True Lord of Ten Thousand Laws starting from Liaozhai.

Old Niu didn't know the specific function of the Heavenly Book; he only knew that there were three things: the Heavenly Book, the Earthly Book, and the Human Book.

However, I have only heard a little about it. The Heavenly Book can manipulate all the laws between heaven and earth, and the Earthly Book can change all the terrain and the rise of earth energy.

As for the Book of Man, it is also extremely special. It can change a person's destiny or even their trajectory, but it is only useful for ordinary people.

This was something Old Niu had heard before, but he wasn't very clear about the Book of Man because he had never seen these magical treasures with his own eyes.

Legend has it that this is a magical artifact left behind when heaven and earth were created.

If it truly is a magical artifact left behind when heaven and earth were first created, then the Book of Humans shouldn't have this function. In the beginning of time, there wasn't even a human race.

Old Niu was very clear about this.

These thoughts kept swirling in his little bull brain. He really wanted to know what Xu Yi was thinking, but Xu Yi wouldn't say. Well, if he didn't want to say, he didn't want to say.

Old Niu didn't really want to know that much; he just wanted to ask Xu Yi, nothing more.

The only thing he wanted to do was stay by Xu Yi's side; there was nothing else worth doing.

Xu Yi and Lao Niu were arranged to live in a yin house.

Xu Yi didn't want anyone to disturb him, so he had already informed Judge Cui in advance.

Judge Cui also assured Xu Yi with a firm guarantee that he would not allow anyone to disturb him.

Xu Yi was relieved. He trusted Judge Cui's work quite a bit. Although the two didn't interact much, Xu Yi always felt that Old Cui seemed very reliable and capable.

After returning to his room, Xu Yi did not fall asleep. This underworld was quite different from the underworld he had imagined.

Xu Yi even felt that this didn't seem like the underworld, but rather like paradise. The people living here seemed to be living a rather carefree life.

However, the underworld of Wude Prefecture seems a bit too crowded lately.

Thinking of this, Xu Yi remembered something: when the underworld of Fangyuan City was disbanded, where did all those wandering souls go?

Logically speaking, Fangyuan City is a subordinate city of Wude Prefecture. If the judge of Fangyuan City were to flee, wouldn't he be heading towards Wude Prefecture?

He wanted to summon Judge Cui to get to the bottom of things, but after thinking about it again, he felt it wasn't necessary to go through all that trouble. Xu Yi felt a little embarrassed about constantly bothering him.

He returned to his room alone and took out the "Ten Thousand Demons Record" from his bosom.

Recently, the "Ten Thousand Demons Record" has been getting quite hot, as if it's trying to remind him of something. However, since the thing can't speak, Xu Yi doesn't know what it's trying to express.

Xu Yi opened the "Ten Thousand Demons Record" and inexplicably turned to the last page. There seemed to be some transparency here, as if something was about to appear.

Xu Yi was a little curious. He gently stroked the paper with his fingers. The paper felt very rough and of poor quality.

However, the cover of the "Ten Thousand Demons Catalogue" feels quite comfortable to the touch. Xu Yi usually doesn't like to open the "Ten Thousand Demons Catalogue" because it feels uncomfortable to the touch, for no other reason than that.

He had a premonition that something terrible might happen after they dealt with the thousand-year-old tree demon.

Moreover, it will be the surprise that the Myriad Demons Illustrated Manual brings him.

As for what it was, Xu Yi really didn't know.

Be patient and wait. Once the Worry-Free Realm is destroyed, the truth will come out.

The tracking talisman in his pocket was already flashing brightly. Xu Yi took it out of his sleeve and examined it carefully. It seemed that Yan Chixia and the others had already arrived near Wude Prefecture.

"Should we go and provide backup?" Xu Yi suddenly had this inexplicable thought.

But then Xu Yi shook his head, deciding against it; there was no need.

Yan Chixia was not one to fuss over trivial matters; he was a very generous and forthright person, and there was no need for him to do such a thing.

Thinking of this, Xu Yi decided to stay in the underworld for a while longer. Yan Chixia would definitely find a way to get in, right?

He was a little tired and wanted to rest for a while.

But my cultivation level is already quite high, so why do I need to rest...?

The thought inexplicably rose in Xu Yi's mind again. He didn't understand why his energy seemed to be running low.

Thinking of this, Xu Yi drifted off to sleep.

After an unknown amount of time, Xu Yi seemed to hear the old ox mooing, and that's when he woke up.

Looking at Lao Niu with a bewildered expression, Xu Yi noticed the worry in Lao Niu's eyes and asked疑惑地问道：“老牛，什么吗？我而已只睡了只短只短的，什么忧忧？。”

In Xu Yi's view, he had just closed his eyes and then opened them again, and it seemed that he hadn't rested for very long.

The old ox was getting anxious. He kept mooing, seemingly expressing his dissatisfaction: "No, Xu Yi, don't joke around. Don't you even know how long you've been sleeping? If you sleep any longer, you'll be sleeping for twenty hours!"

Xu Yi's head buzzed. He'd slept for almost two days? How could that be?!

"That's strange, that's strange..."

Xu Yi shook his head. He just felt that these things were too strange. Was it really that tiring?

Old Niu was quite worried, but Xu Yi showed an apologetic expression: "Old Niu, don't worry, we're about to enter the Worry-Free Realm, so I'm thinking of conserving some energy."

"If we put in a little more effort, we can finish the job sooner and go home sooner."

Xin Jing was still waiting in Xu Yi's sleeve. He was unaware of the situation outside. Before Xu Yi fell asleep, his fellow Daoists in the world of the sleeve were also sealed, and their voices could not travel out. Fortunately, it did not last long, and Xin Jing did not have any particular thoughts in the world of the sleeve.

As long as Xu Yi is alive, everything will be fine. If Xu Yi dies, he will be trapped in this world within his sleeve, never to escape again...

Unless one has a sudden enlightenment and achieves supernatural powers.

Just after Xu Yi woke up, he also released the Heart Mirror. He was only focused on sleeping at the time and didn't think about the Heart Mirror. The Yin energy here is strong, and if the Heart Mirror were to cultivate here, its speed would probably be much faster.

It is also very helpful for the recovery of cardiac imaging.

Moo moo~

Xu Yi felt that Lao Niu hadn't finished speaking, so he looked at Lao Niu again.

The latter, with a serious expression, mooed a few times: "Xu Yi, Yan Chixia has already come looking for you, but seeing that you were resting, he didn't disturb you anymore. Now he and another sorcerer are waiting for you at the City God Temple."

"He told me to inform you that if you wake up, please go to the City God Temple to find him as soon as possible."

These days, Old Niu's words are becoming more and more sophisticated; they're no longer just empty moos.

Xu Yi nodded. Indeed, this time it was he who stood Yan Chixia up.

Xu Yi felt a little apologetic for keeping them waiting for so long, but not much.
