I Sent My Dog to the Past, and It Became an Ancient Dark Emperor?

Qin Tian was a prodigy of the Qin family, yet for unknown reasons his cultivation had stopped progressing, turning him into a laughingstock. Just as he was losing hope, an ancient bronze mirror awakened. A strange light drew a little dog into the mirror. [Item sent in: Black wolfhound] [Time sent in: 10,000 years] [One thousand years ago, Xiao Hei, sent in by the mirror’s master, was born into the Sky-Swallowing Wolf Clan. He was the third son of the Wolf Heavenly Consort and inherited the bloodline of the Primordial Sacred Hound, making him exceptionally gifted!] [To help Xiao Hei build a solid foundation and purify his bloodline, the Wolf Heavenly Venerable fed him dragon liver and phoenix marrow every day, and taught him the divine technique, Primordial Sky-Swallowing Art!] [Five thousand years: Xiao Hei bathed in an ancient spirit spring, gained enlightenment beneath the moon, and broke through to the Dao Palace Secret Realm!] [Eight thousand years: Xiao Hei united the tribes of the Western Barbarians and earned the reverence of trillions of beasts. He broke through to the first level of the Immortal Platform, becoming a half-step great power!] Qin Tian was stunned. Had his Xiao Hei become the ancient Black Emperor?
