A bizarre dungeon descends: I became the father of the monster.

A global series of bizarre instances has descended, leaving humanity unable to obtain food and water by any means. Faced with this situation, countries around the world have mobilized, sending professionals to conquer these instances. However, every so often, a new instance will appear. Apart from China, the United States, and Europe, the political systems of other countries have long since crumbled. To survive, countless people relentlessly pursue their goals, striving to compile all the bizarre instances into a book. Meanwhile, Shen Gui, amidst the groans of despair, toils day and night, his hair nearly falling out of shape, all to design a suitable bizarre instance. "No, this is too easy, I'll starve if the score is too low." "No, this is too difficult, I have to save it for the end of the year, to let the Japanese taste my power."... After three years of honing his skills, Shen Gui finally became a qualified bizarre instance creator. After a blind date, he casually designed a simple bizarre instance. "This week's task target is finally met, a small C-rank, should be no problem, right?" "Wait, what happened? You guys turned my C-rank instance into an S-rank?"
