Then call the bully ~” unwilling to die, Chen Chen endured the “humiliation” of being taken advantage of by the loli, to help him conquer the world of the school bully system, in the new world after the collective human intelligence was lowered, to embark on the invincible stream of pretend life, to become a top talent in the overall development of moral, intellectual, physical, social and aesthetic development to complete!
