Infinite Leveling: Demonic Emperor

[Classic emperor system story]

The fallen prince Qin Feng possesses a demon system. With the power of demons, he strengthens his bloodline, strengthens martial arts, and strengthens the laws of heaven and earth! ... He unlocks contract demon pets and summons the dead heroic spirits of the myriad worlds!

Nuwa can erase all living beings in a single thought, the Howling Celestial Dog can suppress all demon gods in the eight directions with one roar, and Zhuge Liang can command countless troops to wage war in the immortal realm... “Ding, host! We have discovered a goddess from the ninth heaven. Should we strengthen her?” “What’s the point of asking? Hurry up and do it!” A demon emperor holding divine weapons scares everyone so badly they tremble!
