Post-Mythical Era: I don't want to die in the third reincarnation Novel

Across three epochs of Earth's rebirth, calamity claimed each age. The immortals vanished in the first cycle. The dragon race fell silent in the second. Now, in the third reincarnation, humanity teeters on the brink of oblivion. Ding Huan refuses to accept this fate. Determined to survive where civilizations crumbled before him, he must navigate a world stripped of its former protectors and uncover the truth behind Earth's catastrophic cycles. In a realm where each reincarnation brings new horrors, Ding Huan stands alone against the darkness, driven by a singular resolve: to break the curse of extinction and forge a path to salvation.
