Lin Jiu, who unexpectedly had a good joke, was implicated by an alien creature "Ser Cat" one day and had to "hide and seek" in multiple worlds. Every time he goes to a world, he is involved in incredible adventures, including the horror of being used as a "research sample" by the machine tribe, and the absurdity of dancing with the crazy tree in the Kingdom of Spiritual Plants... He bickers with Se Mao, quarrels with Attila, and ignorantly makes different allies, and is always trapped by the power-seeking Dr. Kuman. From a "new human" with unfamiliar skills to one who can resolve crises in the collision of civilizations and become a link between people in many worlds, he turns crises into opportunities with one sentence after another - and finally embarks on the ultimate journey home, waving goodbye to every world and every fetter.
