What You Give Is Not Food, but Cause and Effect

Li Mo was an ordinary delivery boy until he accidentally saved a dying old man who claimed to be the "administrator of the rules of the universe". Before he died, the old man entrusted him with the important task of maintaining the stability of the universe and gave him a shabby "Cosmic Rulebook". The manual reads: Article 1: The speed of light cannot be exceeded. Item 2: Entropy always increases. ... Article 100: All takeaways from parallel universes will not be delivered on time. Li Mo only regarded this as a joke at first, until he accidentally turned to page 101 and found that it was blank. From then on, "bugs" began to appear in his life: he delivered meals to the same customer twice, but the customers were completely different; the alley he entered by taking a shortcut led to a forest composed of giant fungi; he heard another voice of himself at the customer's door. He realized that the rules in the manual were failing, the universe was collapsing, and what filled the 101st blank rule might be his every insignificant choice.
