Genius and Judgment

In the early morning square, a sword pierced his heart; he signed a body borrowing contract with "System ZERO" from another world, at the cost of constantly giving way to different personalities. Since then, the genius high school student Li Shiwen has become a "judge", paying the price with his life, memory and emotions in every on-the-spot "judgment" in exchange for the short-term authority to leapfrog and kill. In order to save Qingmei Linlin who was locked by the "Princess Seal" and was about to be snatched away by the King of Time and Space, he and his companions and the girl in white Wendy embarked on a multi-world expedition: urban stealth, mechanical conspiracy, wilderness contract, and underworld equivalent. The opponents are the Five Pillars, the Legion and the Crown. In the dark, there is also his elder brother who shares his blood but has different ideals, and his younger brother who appears quickly. Protection can become strength, and evil can also be used to achieve justice - in the choice of "justice/evil/temporary judgment", he will gradually unlock the true form of ZERO and face the final judgment of his family and the universe.
