MTL - Killing Grounds of Gods and Devils - Chapter 1140 Flame emperor

After 2000 years has passed, the ruthless demon lord has just been reincarnated! But his aptitude at an academy for nurturing candidates for demon lords is, “Inept”!?

Having the capability to destroy humans, elementals, and gods, after a long period of countless wars and strife, Arnos the demon lord became sick and tired of all that and longed for a peaceful world, so he decided to reincarnate to the future.

However, what awaited him after his reincarnation is a world too used to peace that his descendants became too weak due to a huge weakening in magical powers.

Arnos enrolled in the Maou Academy established to find any students that might be the demon lord’s reincarnation, but his powers are too extraordinary that those in the academy couldn’t properly judge his powers, so he’s regarded as an “Inept student”. Being underestimated and avoided by most people there, he recruited a girl friendly to him, Misha, as his subordinate and comrade, and strives to climb to the top of the demon race hierarchy to one day reclaim his former title and status.

Ji Chen Ai has always wanted to be a good person until he was physically disabled for some reason.

When he is being neglected by his parents, Ji Chen Ai just smiles. When he is being bullied by his brother, Ji Chen Ai just smiles. However, when someone pushes him and his wheelchair down the stairs, Ji Chen Ai can’t smile anymore.

But why is it during this time, that something came out suddenly and tells him that he must be a good person?!

System: Our goal is — No! More! Bad! People!
