Zhang Xuan traverses into a foreign world and becomes an honorable teacher. A mysterious library appears in his mind. As long as it is something he has seen, regardless of whether it is a human or an object, a book on its weakness would be automatically compiled. Thus, he became formidable.

“Emperor Haotian, why don’t you like to wear underwear? To think that you’re still an emperor, can you pay more attention to your image?”

“Fairy Linglong, if you continue to suffer from insomnia, you can always look for me. I have a way with lullabies!”

“You as well, Qiankun Demon Lord, can you cut down on the garlic? Do you want to stink me to death?”

…

This is an incredible story about the heritage between teacher and students, cultivating and guiding the world’s strongest experts.

The Swordmaster who has returned by chance to save the world!

An entomologist’s soul transmigrates into a cultivation world, inhabiting the body of a small, obscure cultivator who specializes in insect manipulation. Reborn, he desires only to avoid conflict and quietly develop in a mortal village.Inspired by the “Sun-Moon Heart Sutra,” he creates his own “Ten Absolute Scripture.” Inspired by the “Nine Deaths Divine Art,” he devises the “Purgatory True Demon Technique.” Moved by the “Eternal Life Sutra.” he extrapolates it into a hundred layers.With boundless creativity, extraordinary insight, and unlimited time, he pioneers new techniques, pill formulas, artifact designs, array formations, gu recipes, poison concoctions, and brewing methods—all entirely of his own invention.While others cultivate paths of slaughter, he alone forges and cultivates the path of self creation.

When opened his eyes, Lin Tian realized that he was reincarnated into the modern cultivation world.

Seeing this person's memory, his expression became gloomy because his identity is a young master from a rich family.

Knowing this, some people might be happy, but not for him.

He had read many modern cultivation world theme novels.

Doesn't the young master like him is a stepping stone for the protagonist, and had a tragic ending?

Just when he was really desperate, suddenly the system came.

[Ding, congratulations to the host for binding the destiny villain system]

[Beginner's prize has been distributed]

[Congratulations to the host for obtaining a martial emperor level cultivation base]

Cool, just slumped, but now invincible?
