Xu Fan didn't care about thirty-seven twenty-one, and he followed out without looking back.

Fu Sheng almost fainted angrily, and Yichuan, who was at the door of Fu Sheng Pavilion, watched his junior brother and sister ignore him for a while, and left. Knowing that something must be wrong, he hurriedly entered the Fusheng Pavilion.

Yichuan looked at the angry Fusheng and asked, "Master, what's wrong?"

Fu Sheng picked up the book of "Heterogeneous Cultivation" on the ground, and angrily stuffed the book into Yichuan's hand.

Scolded: "This evil obstacle, I thought she was just greedy for the love of her children, but who knew that her mind was so impure, and she actually colluded with that ghost shadow man, relying on the crooked ways of the evil sect to promote her cultivation!

Alas, "Heterogeneous cultivation" has long been listed as a banned book by the heavenly realm, this secret book came from five thousand years ago, written by the second generation of the demon lord "Yue Lun" in the demon world, this heterogeneous cultivation can allow cultivators to achieve positive results in a short period of time, and the people of the demon world have increased their cultivation through the secret book of heterogeneous cultivation in just a few years.

Those evil obstacles in the Demon Realm achieved immediate results, and they began to have crooked thoughts, wanting to defeat the Heavenly Realm and become the Lord of the Three Realms.

The 5,000-year-old Great War of Immortals and Demons was caused by this "Heterogeneous Cultivation Technique"! At that time, Demon Venerable Yue Lun led thousands of Demon Realm disciples to attack the Heavenly Realm.

Cultivating the Demon Dao is already damaging to the body, and he likes to kill and bloody aura, and that heterogeneous cultivation technique has even contributed to the killing aura in his body, and this group of madmen is killing in Heavenly Court.

Originally, the Heavenly Realm and the Demon Realm did not interfere with each other, but that time it was really a big battle, although the Celestial Realm won, but it suffered heavy casualties, and hundreds of priests died because of it, which is really hateful!

After the battle of immortals and demons, the group of greedy people in the demon world were also punished, although the alien cultivation technique can be seen immediately, but everything has gains and losses, this second-generation demon Venerable Yue Lun only lived for five hundred years, and his mana was lost, and his hair turned white overnight, and wrinkles crawled all over his body, becoming an old waste.

During those years, one after another Demon Realm disciples suddenly grew old and lost their mana, only those who had not seen the alien cultivation technique were safe and sound.

Many disciples in the Demon Realm began to panic, fearing that the next one would be themselves, and the healthy disciples all gathered together to discuss a great purge of the Demon Realm to eliminate all those old wastes, including Demon Venerable Yue Lun.

The Demon Realm began another bloody killing, and after the new Demon Venerable took the throne, he burned all the different cultivation techniques and forbade this book to appear in the Demon Realm.

However, there were several books of different cultivation techniques in the world that were not destroyed, until one day, several priests in the heavenly realm also had the same symptoms, and they must have secretly cultivated the trickery of the demon path without knowing whether they were alive or dead.

The emperor also began to pay attention to this book, issued a prohibition order, searched the world, and found hundreds of books of heterogeneous cultivation! The emperor destroyed all these books, and sentenced all the priests who secretly practiced this art to death, taking it as a warning!

I don't know how this alien cultivation technique could appear in the world again, and I didn't expect that my sect would have such a greedy and insufficient evil obstacle!"

Yichuan was shocked, and wanted to mention Qu Yanluo to say something good, but now he couldn't say a word.

And Qu Yanluo has already come out of the Taoist Temple at the moment, she really has nothing to defend about this matter, she is completely wrong, but she is a little puzzled in her heart, why would Aunt Lin know about this?

Xu Fan caught up and asked, "Are you okay?"

"What are you doing here?" Qu Yanluo glanced at Xu Fan.

Xu Fan's arms were crossed on his chest, and he said disdainfully: "Why can't I come, it was because you entered the plum yellow rain that I was willing to stay there, and now that you are gone, why am I staying there?"

Qu Yanluo asked again, "You don't want to ask me about that book?"

"No, it's not that I don't know what kind of book it is! Why do you ask that book?" Xu Fan smiled sweetly, not thinking that this was a big deal at all.

"You...... This person is so strange......" At this moment, Qu Yanluo suddenly found that she didn't understand what kind of person Xu Fan was. Before, she only thought that Xu Fan was a naïve little brother, but now she is becoming more and more unable to see through this little brother.

The two were silent for a while, and they had already reached the halfway point of the mountain, when Xu Fan suddenly said, "Heterogeneous cultivation can lead to terrible consequences, do you know?"

"Know!" Qu Yanluo didn't blink her eyes, and said these two words very calmly.

Xu Fan was stunned, smiled knowingly, and said, "Oh, then I won't let this kind of consequence happen to you!"
