——I traveled through time, but something is wrong with this world!
Xia Youshuo, an experimental subject synthesized by the laboratory using the genes of Gojo Satoru and Xia Youjie, was born with inversion techniques and space techniques. As a result, he went berserk due to his ability and directly blew up the entire laboratory into extra-dimensional fragments.
Fortunately, he was fished out by Gojo Satoru and Xia Youjie who were passing by.
——However, this world is far more complicated than he imagined!
Not only are there curse spirits, but there are also fantasy tennis balls!
Yes, you heard it right, tennis! The kind of tennis ball that can create black holes, tear apart space, make people lose their memory, and even fly up on the spot!
Xia Youshuo: "... Is this reasonable?"
Gojo Satoru: "Kid, why did you switch from playing magic spirits to playing tennis recently?"
Xia Youshuo: "... Because tennis is more scary."
Xia Youjie: "?"
Xia Youshuo: "At least the curse spirit won't use the racket to create a black hole."
Intention: work hard
