Recommend me some series where the protag is not a 160 cm manlet who gets amazed at the huge average height of guys at 180. so far the only ones that come to mind are Reincarnator after roids and Re:Monster
How about characters who get taller while they cultivate? xD Like I Shall Seal the Heavens. Honestly though, I usually don't pay enough attention to MC's height, so I can't give more examples.
Conquest... I do not remember his height... there is Da Tang Shuang Long Zhuan, two mc, both become tall too.
Well in the most time its an asian guy who is the protag, and for them 1.80 is considerly big ... i reached that hight when i was 15 ... so its often funny and a bit annoying if the author say this 1.8m is a tall guy.
