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

"Xu Yi, are you ready? I'm going to take you to find out the truth behind all of this."

A sentence inexplicably reappeared in the catalog.

Xu Yi frowned. Go back to the past? How long would that take?

"How long can I stay in the past?" Xu Yi asked the question that had been on his mind. This question was very important to him, as there were still many things in the real world that he had not yet fully resolved.

The catalog reads: "You can stay in there until you remember everything, but time in the real world doesn't change. You've just entered a dream, and perhaps you'll wake up in the next second."

Xu Yi laughed: "I didn't expect you to have such methods. I really underestimated you. I thought you couldn't speak, but I didn't expect you to have such great abilities. You are probably not just the simple 'Ten Thousand Demon Records'."

Xu Yi didn't believe that a simple cheat system could be so useful. The Myriad Demons Record must be related to what they called "before the slumber." Perhaps this time, he would truly understand everything.

The catalog reads: "Through countless cycles of reincarnation, perhaps this is the turning point."

It was yet another nonsensical statement. Xu Yi disliked the feeling of being a riddle-maker and was quite annoyed. He didn't know much to begin with, and now he knew even less, while the mystery only grew.

He didn't even know what this catalog was; it was definitely not a catalog, it was just a disguise.

"Alright, that's enough. Since you've gone to this extent, please take me back. I think I need to learn about the past."

The catalog reads: "Yes, this is the very beginning, and also the era when you first started growing up."

Xu Yi still felt very confused. Was that the era when "I" was first born?

The catalog seemed to understand Xu Yi's thoughts, writing: "Yes, you had just come into this world then, but... anyway, you'll know when you get there."

"You seem to have your own thoughts. Are you spiritual?" Xu Yi asked in confusion. He had never known that the catalog could think for itself. He originally thought the catalog was just a cheat code, but now it seems that it is not that simple.

The catalog reads: "Perhaps so, but I am your creation, and I have no spirit. You know this best."

"However, after I take you back to the past, you'll be all alone from now on. No one knows how you grew up, including me."

"I can only take you back to that time, but this method and supernatural power are not mine. You created them all yourself, including me."

Xu Yi nodded. It seemed this was his best chance to get close to the truth. He nodded and said, "Okay, then I'm ready. Let's go."

After hearing what Xu Yi said, Tu Lu closed the book on his own. He understood Xu Yi's thoughts: to find out the truth was the result Xu Yi wanted.

Soon, to Xu Yi's astonishment, the Myriad Demons Diagram slowly grew larger until it became the size of a door.

Time seemed to stand still around us, and everything was frozen in place.

The whole world began to darken. Xu Yi glanced at the sky; it was dim, gloomy, and terrifying.

Time has stopped, is this how it is? An absurd thought suddenly arose in Xu Yi's mind.

Xu Yi walked towards the door, and after pushing it open, he glanced inside. It was endless darkness, and he didn't know where it led. Nevertheless, he resolutely stepped into the darkness.

In an instant, endless darkness engulfed Xu Yi, first taking away his supernatural powers, and then taking away his immortal sword, turning it into a rusty iron sword.

Xu Yi noticed the changes in his body; perhaps this was his original state.

However, Xu Yi still had no memory of this period of time. He was certain that this was his first time here.

Soon, Xu Yi's clothes were completely eroded, turning into tattered pieces, clearly indicating that they had been exposed to wind and sand for a long time.

As the dark mist dissipated, Xu Yi's figure quickly reappeared in a jungle.

At this moment, a mechanical voice sounded in Xu Yi's mind.

"Ding, host has been detected to have transmigrated to another world. Killing System at your service."

Xu Yi's mind went blank. What was that sound? Wasn't that... the system? He had actually started out relying on the system?

Then wouldn't the "Ten Thousand Demons Catalogue" be a simplified version of the system?

Xu Yi tried to communicate with the system in his mind.

Introduce your features.

"This system aims to help the host become the strongest in this world, until transcendence."

The functions are as follows:

1. Kill any creature to obtain its remaining lifespan.

2. Lifespan can be used to deduce any cultivation technique.

With just one simple sentence, Xu Yi could feel the system's killing intent. This was such a brutal system. Xu Yi didn't understand why the system required him to kill other creatures.

However, Xu Yi had already planted a seed of doubt in his heart. He suspected that things were not so simple. The system disappeared later, so it must be that "I" had discovered something, which led to the scene of the system disappearing.

"Let's take it one step at a time!" Xu Yi didn't want to care about anything else at this point. He wanted to know what the situation was like outside and how to get out of this hellish place.

This place is all wilderness, without a trace of human habitation. Xu Yi even wondered if the "Ten Thousand Demons Record" was playing a trick on him. At present, however, all Xu Yi had was an iron sword in his hand, which was already covered in rust.

"Is this the original appearance of the Immortal Sword?" Xu Yi examined the sword carefully and found that it was indeed somewhat similar to the Immortal Sword he used in his later life. It seemed to be the same sword.

His old buddy is still around, so this swordsmanship should be very easy for him to use. However, Xu Yi has forgotten the divine techniques he once possessed. He currently only knows a simple set of swordsmanship.

Xu Yi didn't like cultivation. All the supernatural abilities he learned were obtained through the Myriad Demon Diagram. The diagram also said that "he" was created by "me" a long time ago. No wonder the Myriad Demon Diagram could nourish his cultivation. This might be one of the reasons.

But where do we need to go now?

Xu Yi lost sight of his target in this grove of trees for a moment.

He tried to recall the supernatural abilities he had learned, even the paper-folding technique or the "Qingxuan Yuyou Chapter," which he had personally seen and practiced. In the end, Xu Yi remembered them.

Drawing talismans and folding paper were his most basic supernatural abilities, abilities he had genuinely learned. However, he was currently somewhat rusty in using them, or perhaps, Xu Yi lacked magical powers and didn't know how to use these things anymore.

Just as Xu Yi was about to recall something, he felt a drop of sticky liquid fall onto his head.
