Zhang Heng had mediocre aptitude in his previous life and struggled to break through despite years of cultivation. After an unexpected awakening of the Profound Capture Platform, he gained the ability to travel between worlds. His true body cultivates in the vast universe realm, while his soul clone enters the Profound Fiend Realm, a world filled with baleful energy, demon clans, and Dao soldiers. Even if his clone dies, his true body can return, but each death carries risks and brings him closer to deeper secrets. In the Profound Fiend Realm, Zhang Heng relies on alchemy, Dharma seeds, and cautious planning. Starting as a retainer of the Zhao clan, he becomes entangled in the Zhao and Wei clans' struggle for the position of city lord of Yancheng. He trades pills for resources, refines Dharma seeds such as Copper Skin and Iron Bones, and practices a dangerous cultivation technique that connects all 365 spiritual acupoints.
