"Come in, the door is unlocked!" Hearing a knock on the door, Chu Fei's voice immediately came from inside the room.

Lin Fan unscrewed the door and walked in, and after closing the door, he found Chu Fei lying on the bed.

"Senpai!"

Seeing Lin Fan come in, Chu Fei immediately sat up and said, "Don't scream one by one, it sounds awkward, in fact, I'm only ten years older than you, find a place to sit by yourself!"

Lin Fan was embarrassed for a while, in fact, he was a little awkward to call him like this, "Then I'll call you Brother Chu." ”

"Whatever!" Chu Fei shrugged.

"Just ask any questions, but I have to tell you in advance, there are some questions that I may not necessarily answer you!" Chu Fei knew Lin Fan's intentions, so he didn't talk nonsense.

Lin Fan smiled, and after slapping the draft in his heart, he said: "Brother Chu, you said that you once promised someone to protect me, I don't know who that person is, and what is the connection with me?"

"I can only tell you that that person is an elder whom I respect, and as for what he has to do with you, I can't tell you right now, and when the time comes, I will take you to him personally. ”

Hearing Chu Fei say this, Lin Fan could only skip this question for the time being, and then said, "Brother Chu, what did you mean by the other world before? Is there another world besides our world?"

Because Father Duan also mentioned another world in his letter, and Duan Fei's mother was from another world, and it was also someone from another world who killed them, so Lin Fan was very curious about this other world.

"That's right, it's a world with a completely different cultivation system, but it's also in the same vein, if you have to define it in one sentence, it's a world with a higher power system, not comparable to today's martial arts. ”

Lin Fan nodded, no wonder Father Duan would ask him not to take revenge in the letter, saying that the enemy was unprecedentedly powerful, and he was not even willing to reveal the name of the enemy to him, a person with a power system far stronger than this world, it was easy to kill the people of this world.

"Brother Chu, I think you should have been to that world, right?"

Chu Fei nodded, he hadn't just been there, he was a strong man in that world, and he had his own territory, but he didn't tell Lin Fan about these for the time being, because he wasn't sure what Lin Fan's future achievements would be, if Lin Fan couldn't even break through the threshold of life and death in his life, then there was no way to go to that world, then there was no point in telling him these things.

After having a general understanding of that world, Lin Fan took out a secret book from his body and put it in front of Chu Fei, and said, "Brother Chu, do you know this secret book?"

There was no way, Lin Fan didn't have a Gu Wu friend by his side, and now he couldn't find a suitable candidate except for Chu Fei to help take a look. In order to be afraid that this Mixed Yuan Heart Sutra would fall into the hands of others, after leaving the East China Sea, Lin Fan put the Mixed Yuan Heart Sutra all the way on himself.

"Mixed Yuan Heart Sutra!" Seeing the four big characters on the cover, Chu Fei was stunned for a moment, and then he looked at Lin Fan and asked curiously, "Isn't this cheatbook in Penglai, where did you get it?"

So, Lin Fan told him how he got this cheatbook, and then asked, "Is this cheatbook very powerful, why do so many people want to get it?"

This question, Chu Fei is really difficult to answer, he has only heard the name of the Mixed Yuan Heart Sutra, but he has never seen it. At this moment, he was also a little curious about this "Mixed Yuan Heart Sutra", so he looked at Lin Fan and said, "It's convenient for me to turn over the contents of this book!"

"Of course!" Since he took it out in front of Chu Fei, he didn't think that Chu Fei would pay attention to this cheatbook, because his sixth sense told him that Chu Fei was not such a person.

Chu Fei picked up the Heart Sutra and flipped through it, but when he looked at it, he was a little surprised, not because he was shocked by the unfathomable martial arts inside, but because it was actually a secret book about spiritual power cultivation. It's no wonder that the Mixed Yuan Heart Sutra has been practiced by no one except for the Dao Ancestor who wrote this book.

The foundation of Gain's spiritual power cultivation is the pinnacle of martial arts, and it is necessary to break the threshold of life and death.

"It's worthy of the Mixed Yuan Heart Sutra! Sure enough, it's as broad and profound as the rumors, I didn't expect there to be such a strange book in the ancient martial arts world!" Before, he had only heard the name of this book, but now after seeing the content with his own eyes, he couldn't help but have a deep respect for the Dao Ancestor who wrote it, this Dao Sect Ancestor was definitely an amazing genius.

Lin Fan even a person as powerful as a sword immortal like Chu Fei had such a high opinion of the Mixed Yuan Heart Sutra, it can be seen that the power of this Mixed Yuan Heart Sutra is definitely extraordinary, and he can't help but be happy in his heart, if he practices the martial arts here, wouldn't he become very powerful?

But as soon as this thought arose in his heart, Chu Fei splashed down a basin of cold water, only to drench his whole body cold.

"You should put away this cheat book for now, don't try to practice the martial arts above, otherwise, the light ones will go crazy, and the heavy ones will die. Chu Fei closed the cheats and warned Lin Fan with a serious face.

Lin Fan was shocked when he heard this, "It's so serious, you can't practice at all?"

Chu Fei nodded, "It's not that you can't practice, it's that it's not yet time to cultivate." ”

Lin Fan looked confused, he didn't quite understand what Chu Fei meant, what is not the time to cultivate, then when is the time to cultivate? But since the other party warned himself so seriously, it should be true, he didn't think that Chu Fei had the need to deliberately scare himself.

Seeing that Lin Fan didn't seem to understand, Chu Fei softened his tone and explained, "At least wait until you break through the threshold of life and death!"

"What is the entrance to life and death?" Lin Fan asked curiously.

"That is the necessary threshold to step out of the martial arts, whether you can step into a new field, it depends on your ability to break through the threshold of life and death. After that, from now on, the sky is high and the sea is wide for you to swim, and if you can't get by, you can only become an ant in the eyes of the mighty, and you may even be wiped out by cultivating for a while!"

When Lin Fan heard this, although he didn't understand it very well, his face was also unprecedentedly dignified.

Out of Chu Fei's room, Lin Fan was just about to return to his room, when he saw Bai Suxin standing at his door, he seemed a little hesitant, not knowing whether to knock or not.

Lin Fan was stunned for a moment, although he was not used to how to face Bai Suxin, he still walked over, "Aunt Bai, are you looking for me for something?"

Bai Suxin turned around when she heard the voice, put away a trace of hesitation on Fang Cai's face, and returned to her cold appearance and said, "Oh, it's okay!"

Lin Fan chuckled lightly, knowing that she had put down the palace master's shelf, and was embarrassed to speak, so Lin Fan said directly: "If Aunt Bai wants to ask me about Lin Fan, let's go into the house first." ”

After entering the house, looking at Bai Suxin, who was not used to sitting, Lin Fan slowly told the trajectory of his life in his previous life.
