Have I Become a Grass God?

After three hundred years of imprisonment, Little Lucky Grass King made a dangerous wish in his loneliness—— She wants someone who understands her existence. Then, a soul from another world came to Xumi. The law of another world collides with Teyvat, giving him a status that rivals the world; but he is disabled and unable to control this power. Every panic thought is giving birth to "what if", and every false possibility is feeding the forbidden knowledge of the abyss. The dead realm spreads, the earth's veins become corrupted, and the demon scale disease erodes wisdom. When the pollution is about to break through the national border, World Tree activates the underlying defense and shuts down the logic of the entire country. In order to end this catastrophe, Nacida made the craziest decision: she grafted her name, destiny, and connection with the World Tree to this strange soul. "From this day forward, you are Nasida." When the omniscient authority breaks into the consciousness of mortals, when the abyss rages in the closed cage—— The newly born "Nasida" opened her eyes and stared blankly at the blackened records. How should he (she?), As a god, save this world that has just accepted him?
