Slay the Gods + Great Qin + Primordial Chaos + crossover.
Between one breath and the next, the Ancestral Dragon changed the protagonist's bloodline to that of the Ancestral Dragon.
Thus began his journey to become the Ancestral Dragon.
The Ancestral Dragon made a pact with Bai Lifeng, another adopted son of the Bai family who had transmigrated, to protect Huaxia from foreign invaders.
With a single promise, "Within Huaxia, no foreign gods may pass. Beyond the mist, all shall be slain," he obtained the Ancestral Dragon's bloodline.
With one stomp, he shattered the dwelling place of Egypt's gods. With one palm, he crushed the temple of Cthulhu.
For Nyx, he flattened Olympus. Alongside Lin Qiye, he became a true Dragon God, bringing the Great Wall down from the skies above Takamagahara and permanently confining its gods to a narrow territory.
He took Zhou Ping as his underling, awakened his swordsmanship, and guided him to the Dao. His sword subdued the Fifth Universe, making him the greatest emperor of all time.
All he wants is to quietly watch Lin Qiye draw out supernatural fertility...
Not bad,
