Lin Fan, a modern "living young man", accidentally traveled to a different world, only to find that he was not "alone". His body is actually a strange "soul container", which contains hundreds of soul fragments from different time and space, different civilizations, and different races. There is the remnant soul of the ancient sword fairy, the consciousness of the future technology boss, the will of the alien demon god, and even the instinct of an ancient ferocious beast. These soul fragments are independent of each other but influence each other. Each personality has unique memories, knowledge and skills.
At first, Lin Fan was tortured by these "roommates". The control of his body was often fought for, and the use of skills was also chaotic. But he soon discovered that when he learned to communicate, negotiate, and even reach some kind of "consensus" with these souls, he could use the abilities of multiple souls at the same time and explode with power far beyond ordinary people. He can use the experience of the Sword Immortal to perform sword skills, use the knowledge of a technology boss to analyze formations, use the will of the devil to intimidate the enemy, and use the instinct of a ferocious beast to sense crises. However, these soul fragments are not all well-intentioned. They also have their own obsessions, desires and purposes. Lin Fan must seek survival and development amidst internal balance and external crises, and eventually become the true "co-owner" of these "hundred souls", condensing into a "collective life" that transcends individual limits.
