Tang Long was brought to the Immortal Cultivation World by an immortal who noticed his affinity to wood and cultivation.
Relying on his amazing talent, became one of the five emperors of that world.
He failed his Heavenly Tribulation and had his soul scattered into pieces but one part found its way to Qin Haodong on Earth.
With his excellent medical skills, he became a divine doctor of traditional Chinese medicine and encountered the baby girl he made before going into the Cultivation World, whose mother was as pretty as a fairy. The little girl even asked him to find more lovers. What a cute girl…

Li Xuan traveled through the world of immortality and opened the apprentice system, and both apprentices and apprentices could be rewarded for upgrading.

【Ding! Accepting apprentice Qin Yue, reward you: Innate Divine Power]

【Ding! Accept the apprentice Zhao Tian, ​​reward you: call the wind and call the rain]

【Ding! Apprentice upgrade, reward you: space shuttle]

….

Li Xuan, who accepted a bunch of apprentices, evolved infinitely in seclusion.

Ten years later, the Devil Emperor invaded and wanted to sacrifice the whole world, but no one could stop it. The disciples watched the world fall into despair in pain.

At this time, Li Xuan appeared and slashed a sword against the Demon Emperor under the watchful eyes of the public.

Boom!

The sky fell apart, the invincible Demon Emperor fell on the spot, and the entire dark world was swept away by a sword.

The disciples were horrified. It turned out that the strongest person in the world was actually the master who had been in seclusion for ten years.

3000 years after his disappearance, Xue An had undergone cultivation and came back as an invincible fairy. But upon his return to Earth, he realised that he had a pair of twin daughters.

“Papa, this dragon doesn’t taste good!”

“Oh, this must be an ancestor-grade dragon that has lived for much too long. Its meat has become a little dry. Next time, we shall eat a young dragon within ten thousand years of age.”

Some dragon that had existed since the beginning of the universe was lying on the floor, trembling and shivering.

“Papa, between you and the other Immortal-emperor mannies, who is more powerful?”

Xue An smiled. There was not a single soul that could withstand even just one blow from him. If there was! That would at most be two!

“My dear daughters, I will make you girls the happiest princesses in this whole, wide world. No, in this whole universe! And it’s the two of you!”
