Immortal, Starting From The Library And Conquering The World

This is a world of monsters and demons. Su Chen traveled through time and got the seed of immortality, and became the little black eunuch of the Daliang Palace. In order to obtain immortality and protect the Taoist immortality, he started the path of spiritual practice.
"As time goes by, I don't know how many emperors and heroes, martial arts heroes, immortals and demons have been buried. I can only sit and watch the wind and clouds, and move forward in the wind and sand of history..."
The first realm of immortality, the ripening medicine.
The second realm of immortality, changing appearance.
...
Just like that, under the hibiscus tree, he buried his world-famous friend Dongchang, who was nine thousand years old, on a rainy night. With his sword, the wind and rain shocked the world. Only then did the world know that this cripple who had not left the library for ten years was actually an unparalleled evil god. Pride; in the pharmacy, for the kind old man who had been with him for three years, he stirred up trouble again, stirred up the world, and made the world wake up from his dream, thinking of the world's number one traitor...
...
Eternal life is a lonely road, maybe.
But for thousands of years, the young man who walked out of the library has been stirring up trouble in the world! He was buried in the sky, buried on the earth, and buried all living beings! Gods, ghosts and monsters should also be called Demon Daozu!
