[Passionate + slow burn + no System + growth + wielding beast souls] When strange beasts die, their bodies rot, but their souls endure! Beast souls enter the body, rebuild the flesh, and return to the world! Xu Yan is accidentally brought to a world overrun by strange beasts through “Oblivion.” Here, the Sky-Shrouding Thunder Roc soars through the nine heavens, the Earthfire Mystic Tortoise rises among the mountains, and the mighty Iceblood Dragon freezes an entire region in an instant! Eight-Armed Demon Apes, Heaven-Swallowing Giant Serpents, Ancient Sacred Wolves: all kinds of world-destroying beasts rule their own territories! In this world, the beasts you wield can evolve into gods!
It's well written, but it's a pity that no one read it.
