Kai of the Sorcerer’s Tower is one of the last mages left, barely surviving in a world ruled by creatures of the dark — where the era of mages ended, and most of the lands got contaminated with dead mana. To save his world and fulfil his master’s last wish, he put himself through a forbidden ritual, risking his soul being ripped into pieces to make his way into the past. In an era with abundant mana — an era yet to enter the Golden Era of Magic. Things go wrong, of course, as they always do, and he finds himself thousands of years before the world fell to mana contamination — in the body of a young lord, Arzan. All is not well, though, as the young lord was murdered by someone right at the cusp of a beast wave threatening the territory, while larger threats loom on the horizon. There was a lot to do for Kai to regain his former strength in this time of primitive technology, but then again, he might just be able to change that.

After a vacation, when she returned to her country she caught her fiancé cheating. She angrily left and disappeared.

Five years later she returned with her talented kid. Afterwards, her son participated in the piano competition. Unexpectedly her son actually came looking for his father.

“The camera on this side, take me to take a look! My name is Xiaoxi my mommy is called Tang Siyu and she’s very pretty! I’m four and a half years old this year. I’m looking for my father, you probably look like me, please be sure to contact me, oh!”

After that, he was gone from the front of the camera again and said, “Oh, I’ll wait for you!”

In the background, a woman became mad. A few days later, a mysterious man came to their doorstep and claimed to be Little Xi’s father.

Tang Siyu looked at this tall and handsome man, who her son was a carbon copy of, and then became angry.

Five years ago, the bastard who pinned her down was him?
