The Legend of the Qing Emperor

Wan Qing, a student in the Department of Archeology, discovered ancient underworld ruins in Kunlun Mountain and his body mutated. Therefore, he unintentionally got involved in an eternal war and traveled to the "Beidou Star Territory" on the other side of the starry sky. In the Beidou Star Territory, Wan Qing received the inheritance of immortal weapons, fought against the immortals in the era when the fairy realm was not visible, resisted the dark chaos sweeping the universe, and finally became the great emperor of the demon clan.
