World Restoration Guide

In the college entrance examination room, seventeen candidates disappeared out of thin air. The physics questions on the test paper began to violate the laws of nature - the ball rolled upwards and the water flowed upwards. When everyone was screaming and waiting to die, Chen Xuan picked up a pen and wrote a line on the paper: "The direction of the friction force was wrongly marked. It has been corrected." The error was fixed. He turned to the next question. He has a problem: he feels uncomfortable when he sees logical errors, and he can't sleep until he corrects them. This problem later became known as "World Repair". He was recruited into a non-existent institution - the Institute for Cognitive Anomalies. There is no immortality here, no magic. His colleagues were physicists and mathematicians, and they told him: This world is a half-written draft by the creator. The creator ran away, and the bugs left behind are spreading on their own. That door that shouldn't exist, that corridor that never ends, that smoke that swirls in your retinas - they're all errors in the draft. And you can fix them. Chen Xuan thought his job was to fix bugs. But he soon discovered that some mistakes had been deliberately left unfixed. The manual has been tampered with. All bugs signed with "E" have never been successfully fixed. Three years ago, a definer named Su Yuan discovered the embryo left by E-a backup that could format the entire world. Then Su Yuan disappeared. "Stop checking. You've seen too much." Chen Xuan looked at the person who warned him and asked, "Who will fix these mistakes?" When the whole world was in fear and weirdness, he pushed up his glasses: "This rule application question has a formula."
