On the eve when the doomsday game 'Ten Thousand Beasts Continent' descends into reality, Liu Mang, a player who died tragically in his past life, is reborn as the ancient Titan python — the very one that sacrificed itself to protect him — binds to a system and evolves frantically by devouring prey. From a young snake he fights all the way to the peak of the legendary realm. He crosses paths with Man Tianxing, a reborn wealthy young lady, who recognizes him as her destined Divine Beast; they support each other with all their might. He bides his time to take revenge on his ex-girlfriend, who once used a giant ape to cause his death, and prepares day and night, vowing that on the day the game invades reality, he will rewrite his doomed fate from the past and settle every score.
