Review Detail of Surya23 in The Tale of the Void Emperor

what crap is this. first the author say that MC will be weak and gradually become powerful. but in 10 to 20 chapters he became super human with no logical explanation of many things. Then there is harem where MC even gets more powerful. if u know what is sex, u should know energy is consumed in the act and can't enhance power of someone. even if it is fantasy, make something logical atleast. ..
