Review Detail of Weirdo in World's Best Martial Artist: Billion Times Talent!

This has a predecessor novel in mtl... The title is reiki recovery, just search it.. It also a billion times talent starting from 10 or 100 times, I forgot.. The mc is an old man, also an old soldier of cataclysm war.. If you had read that, this one will feel bland.. I know, because I had read it..
