Jiang Cheng transmigrates into the Perfect World during the catastrophic Era of Emperor Fall, finding himself a doomed descendant of the Nameless Quasi-Immortal Emperor. With his ancestor destined to die in the Ultimate Ancient Land and his entire clan facing annihilation by the darkness, Jiang Cheng's future seems bleak. However, he awakens a unique Golden Finger: a video editing system linked to a Myriad Worlds Video Website.

This platform connects countless fictional universes, from Battle Through the Heavens to Madoka Magica, allowing users to share content across dimensions. Jiang Cheng realizes he can edit realistic videos depicting stories from his past life, shocking viewers from other worlds with tales of their own futures or hidden truths. By gaining popularity and views across the multiverse, he earns cultivation rewards capable of defying heaven itself.

As characters like Hun Hun Tiandi and Xiao Yan watch in awe, Jiang Cheng begins his countdown of legendary triologies, questioning the very limits of lifespan and power. Can he rewrite destiny and save his lineage before the darkness consumes all?
