My Immortal Beast Tower

Stricken with a fatal illness, facing a lonely death, Chen Xuan, a humble orphan, watched his last day dawn. His life was destined for obscurity, a mere blip in the vast, unforgiving world of cultivation. But just as despair set in, a mysterious black tower, his only inheritance, flared to life, whisking him into a secret pocket dimension. Inside, a frigid cold pool not only jumpstarted his immortal cultivation, propelling him through realms at breathtaking speed, but also granted him the forbidden \"True Art of Controlling Spirits.\" The catch? This explosive growth came at a terrifying cost: his very lifespan. Yet, the tower harbored another secret—the power to mutate his tamed beasts into peerless, terrifying companions, granting them abilities beyond imagination. Now, armed with an unparalleled army of monstrous, mutated allies and a rapidly depleting life force, Chen Xuan must race against time to ascend. Can he conquer the immortal world and secure true longevity before his borrowed time runs out, or will his ultimate power lead to an unbearable price?
