Luo Yu is a social animal, and his biggest wish every day is to lie down and play games after get off work. Until one day, he accidentally triggered the mysterious "skill jamming system". Every time he uses a skill, he will randomly draw abilities from different worlds - but the side effect is that his soul will be exchanged with the sender when using the skill. So, when he was eating skewers at a roadside stall, he suddenly traveled into the body of the heroine of a science fiction romance novel, and was forced to use his "electromagnetic control" ability to help the boss stop bullets; when he stayed up late and worked overtime, his soul was dragged into the doomsday wasteland, and he used his "healing aura" to revive mutated zombies. Every soul exchange is a social death scene. Luo Yu just wants to lie down quietly, but the system forces him to be the savior of all worlds. What's even more outrageous is that he found that the skills he was involved in were getting more and more outrageous: the sword energy of the ancient martial arts world, the forbidden spells of the magic world, and even the flying sword of the immortal world. And every time after soul exchange, he will leave a "skill mark" - the other party can also use his abilities. Luo Yu suddenly realized that he was not intruding, he was connecting the world. And every time he saves someone, there is one more "clone" who can use his abilities. When the cracks came and the world collapsed, all the clones appeared at the same time, and Luo Yu's lying figure became the final salvation for all the worlds.
