Demon Boy: After Secretly Learning Immortality, I Have a Showdown

After the end of the world, Bu Fan traveled to another world and was an atavistic boy with an evolutionary system that kept evolving and rising. The rise of the demon clan even alarmed the great god Zeus, the righteous god of ancient and modern times, and the god of Hou Tu Ming. He sent the twelve forbidden gods Fengdu, Disha, and Kong Xuan to crusade against the demon clan. This battle shocked the world and made ghosts and gods weep. The battle lasted for 999 days and 999 nights. It can be called the first of its kind in history.
