Reborn: The Taekwondo Prodigy's Second Chance

Everything was good until the end, it became a sci-fi. . . still, prior to the ending, i loved everything. I regret reading after it said 'The End'. Personally, I didn't like the side stories and the 2nd book, I'm already satisfied until chapter 905.

Its like collecting a wife novel.
Basically MC is an ancestor with peak power of his world and have a system.
Theres many r18 scenes

I can't say or provide much more than that or it will truly spoil everything, but as they say . . . the plot thickens.
