The male lead, Lin Aotian, transmigrates into a world of cultivation and unexpectedly obtains the **Life-Exchange System**.
Just as his sect, Zhengxiao Sect, is on the verge of being wiped out, he sacrifices his own lifespan to boost his cultivation and annihilates the invading enemies in one strike. But soon, he discovers that he can absorb his enemies’ remaining lifespan to strengthen himself.
And so, within the righteous path, a terrifying demon lord emerges—one who takes lives to extend his own.
Killing his way forward and plundering lifespan from every enemy he defeats, Lin Aotian leads his sect, disciples, and descendants on a ruthless path to dominate the entire cultivation world.
