After transmigrating to another world, the male lead is bound to an absurd parasitic system. Starting from a pimple on a world-destroying giant beast, he copies skills and earns skill points by parasitizing various creatures, crashing hosts, and completing "impossible actions". Laughter abounds all the way. Originally, after getting acquainted and accompanied by Cai Wei, he would be able to live a happy and blissful life, but the other world is not as peaceful and wonderful as imagined. Unwilling to let important people encounter danger again, the male lead begins to build his own forces.
