All the People Will Become Gods, I Will Become an Immortal

When six billion humans around the world traveled across time and became wild gods, I traveled across time to become an immortal. In this world, there are no immortals and gods, demons and demons are everywhere, dynasties are in decline, and corpses are everywhere. Six billion wild gods developed believers, cultivated followers, exorcised evil spirits, and ascended to the position of emperor of heaven, but I became an immortal.
