the concept is good but execution is bad
having 1 or 2 abilities from heroic spirits have been enough but author included the so called formulas knowledge etc and all memories of heroic spirit
And mc not able to utilize it fully is also a letdown
Mc is quite hypocrite and says one thing and does another
He is also insane and somehow wants to destroy world for ridiculous reasons
Full of negative attitude
He only sees cons but not pros
Mc and the author are unstable and are insane mentally
if you are a fan of Tang San then you will like it, i guess
Mc is 1 year older than Tang San and well tang is the main character and HE is side kick
wasted first 12 years , no use of previous life memory ,connections , self made spirit ability , after first 2 chapter no efforts whatsoever
