No cheat code, right? I'll make one myself.

After spending some time memorizing the contents of the "Card", Yunlin closed the book and gently placed it on the table. He looked back and saw Mu Geng sleeping on the bed and sighed.

According to past experience, Mu Geng would not get up when the sun rose until the next day. Yunlin did not have an extra bed, so in the past, when he encountered such a situation, he would spend the night lying on the table.

But today was a little special. Yunlin planned to start practicing the contents of the "Cards" tonight. Seeing that Mu Geng had fallen asleep, Yunlin didn't care whether there was dust on the ground. He just sat cross-legged on the ground and closed his eyes.

According to what was written in the book, if Yunlin really wanted to practice, he needed to create a soul jade in his body. To create this soul jade, he needed half of his soul and a large amount of spiritual power.

The spiritual power is fine, Yunlin’s Dantian still stores most of the spiritual power, which can be used to shape the soul jade.

But half of the soul is a bit troublesome. The soul is closely related to a person's life span. If half of the soul is lost, the person's life span will be permanently shortened by half. That is to say, even if he breaks through the realm and his life span is extended in the future, Yunlin's life span will be much lower than that of others.

Moreover, this method may not be successful. If it fails, Yunlin will lose half of his lifespan in vain, and the next time he tries, he will still have to lose half of his remaining lifespan. The book also says that a person can only try three times at most. No matter how many lives he has, by the fourth time, his soul will dissipate because it has been divided too many times.

However, the fact that Yunlin sat down cross-legged after reading it showed that he had made up his mind.

If he maintains the initial stage of Qi training, his life span will be about 200 years, but after breaking through to the foundation building stage, his life span will be able to increase to 500 years. Even if he loses half of it, it can still increase to 250 years. After forming the pill, it can increase to 1000 years in one go. If successful, he can also live up to 500 years.

One advantage of having a low level of cultivation is that it is easier to increase one's lifespan. Many medicinal herbs that can increase one's lifespan are not very effective only when one's realm is high. When one's realm is low, medicinal herbs that can increase one's lifespan are not expensive.

Therefore, Yunlin is not afraid of losing half of his lifespan.

Yun Lin closed his eyes, and his spiritual power turned into a sword. He looked at the other Yun Ling in front of him and said, "I'm going to kill you. Are you afraid?"

"I am you. If it can help you, go ahead. Besides, these chains wrapped around me are making me very irritated. If possible, cut them off together."

The other Yunlin looked at the sword floating in front of him and said with a smile.

"Then I'll do it."

After saying this, he raised the sword high up, and the next moment, it cut into two pieces along with the chains wrapped around Yunlin's body. The lower body of Yunlin slowly turned into a small black ball, and the upper body of Yunlin flashed and instantly turned into a complete body, but looked a little weak.

At the same time, the real Yunlin spat out a mouthful of blood, and his black hair began to have scattered white hairs.

After cutting off the body, the sword of the spiritual world dissipated directly as if it had completed its mission. Yunlin, who had become whole again, opened his eyes, grabbed the black ball that his lower body had turned into, and then countless spiritual powers gathered on the black ball.

The aura of Yunlin in the real world began to decline continuously, his initial Qi training skills quickly disappeared, and the black ball in his mind turned into a black ingot.

When the black ingot took shape, Yunlin opened his eyes, wiped the blood from the corner of his mouth, stood up, found a rag, wiped the blood on the ground, and then smiled.

He didn't expect that he would succeed in one try, and because his soul was cut off this time, his lost memory also returned.

After having the soul jade, Yunlin's problem of absorbing spiritual energy slowly was solved. This was because the soul jade in his mind would absorb the surrounding spiritual energy to strengthen itself. More importantly, his cultivation level in the early stage of Qi training did not disappear, but was only transferred to the soul jade. If he wanted to use it, he could reach the level of the early stage of Qi training at any time.

Another benefit he gained was that his lost memories returned.

At the beginning, Mo Lin made Yun Lin's memory disappear by simply putting a seal on his soul. But now, this seal disappeared along with his broken soul, and his memory came back. Although his previous memories didn't seem to be of much use to him now, he always felt that he was incomplete after losing his memories. But now, he has become complete again.

"If I follow what the book says, I should be at the second level of Black Iron, which is the early stage of Qi training. If I can reach the fourth level of Black Iron, I will be at the middle level of Qi training. The eighth level of Black Iron will be the late stage of Qi training, and the tenth level of Black Iron will be the completion of Qi training."

After tidying up a bit, Yunlin turned on the light and started to read the "Cards" again. Because he had not officially started practicing before, Yunlin had only glanced at some parts. Now that he has started practicing, he naturally has to read it carefully.

This glance really made him discover the differences.

Compared to the first time he read it, the book seemed to be thicker, and Yunlin was sure that there were two pages in the book that he had never seen before.

"Being able to see the hidden content means that you have successfully cultivated. Since you can understand the content of this book and successfully cultivate, it means that you are not a native of this world. Because I have tested it, only people who come from other worlds can cultivate. I traveled from a place called Earth. I was hit by the time travel artifact and woke up to find myself here."

"I won't say more, after all, there are only two pages of the book that can be hidden. I will just tell you the main points. The Soul Jade is a cultivation method that I discovered myself, but I haven't practiced it myself. I don't know what it does, but it should have some magical effects. After all, it can automatically cultivate itself, which makes it very valuable. You can try the Soul Jade yourself to see if it has any other effects. Feel free to test it boldly. The Soul Jade is not as precious as you think. It is very solid."

After reading the above passage, Yunlin was shocked. It turned out that he was not the only time traveler in this world. This also explained why this book was written in Chinese characters.

But from his description, he didn't seem to have met Morin.

"Does the Soul Jade have other uses?" After calming down, Yunlin focused his attention on this sentence. After all, he didn't know when this book was left in the library. Instead of caring about where the person who wrote this book was and whether it had any use, he might as well take a look at the useful information.

“It seemed like I could add a feature that would do what I had in mind.”

"Brother has the golden finger, but you won't give me any help, right? It's unfair to others, right? Then I will build it myself. Just create a system within your reasonable range."

Yunlin couldn't help but say this after vaguely feeling that the Soul Jade had another function that could be added.

Although his voice was not loud, it woke up Mu Geng who was sleeping.

Mu Geng rubbed his sleepy eyes, climbed out of bed, and asked unhappily, "Yunlin, what are you mumbling about in the middle of the night?"

Yunlin saw Mugen wake up, with an awkward smile on his face, and explained: "I'm sorry, Senior Sister, I was so engrossed in reading that I accidentally talked to myself."

Hearing this, Mu Geng rolled his eyes at him and complained, "I thought you were talking in your sleep, and you woke me up."

Yunlin smiled sheepishly and said, "Senior sister, go to sleep, I won't disturb you anymore.

Mu Geng waved his hand, lay back on the bed, and said, "Okay, you should also go to bed early, as you still need to continue training tomorrow."

"Well, good night, Senior Sister." Yunlin responded and continued to flip through the "Cards". He was full of curiosity and wanted to try the new function of adding soul jade.

"If I were to say what ability I want most, it would be the ability to travel through time and space. After all, I still want to go back and see my parents." As he thought about this, Yunlin discovered that some very strange patterns had appeared on his soul jade, and the information about adding abilities in his perception had disappeared.

"Will it be added successfully like this?"

Yunlin looked at the two buttons that appeared in his mind, one for confirmation and the other for cancel, and was speechless.

Apart from these two buttons, there were no other hints, and he didn't dare to choose anything casually.

After hesitating for a while, the two buttons began to slowly disappear, as if their existence was limited. After a while, the two buttons in his mind completely disappeared, but in contrast, an energy bar appeared between the two buttons, but the energy bar was empty at this moment.

"It seems that I need something to charge before I can use this function. But energy is conserved. If you want to achieve something, you must pay something. But here I can use spiritual power to charge, but after I return to Earth, what should I use to charge so that I can come back?"

Thinking of this, Yunlin's high emotions suddenly calmed down. Although he was happy to be able to return to Earth, he didn't want to stay on Earth for the rest of his life. After all, compared with Earth, this world was more interesting.
