Immortality begins with exchanging talent attributes.

Transmigrating into the body of a temporary jailer in Qingzhou County's prison, Zhou Yan started with only the gray talent attribute "Innate Residual Meridian." His meridians were blocked, his physique weak, and he only had four years to live. The good news was that he could see everyone's attributes. The even better news was that he could change them. But there was also bad news: to exchange, he had to sacrifice his lifespan. He traded "Innate Residual Meridian" for "Copper Skin and Iron Bones." He traded "Copper Skin and Iron Bones" for "Hundred Tribulations Vajra Body." While others practiced martial arts, he traded attributes. While others risked their lives, he "wasted" his life. Starting from the county government's death row, Zhou Yan continuously exchanged, merged, and increased his lifespan, ultimately becoming the most difficult person to kill and the most unapproachable person in the world.
