Time's Echoing Coffin

The universe is woven from 840 million temporal rifts—each housing civilizations from different dimensions where time flows at impossible speeds. When these rifts collide, reality fractures. Ancient coffins drift through the void, carrying secrets that predate existence itself. One young cultivator discovers he can navigate these temporal storms, unlocking powers that defy the laws of causality. But every rift crossed brings him closer to the truth: someone is orchestrating the collapse of all timelines, and the coffins are not tombs—they're weapons.
