Weird Story About Rules: My Sanity Is Bottomless

When "The Realm of Rules" came to the world and randomly selected "visitors" to enter the fatal copy, Chen Mo found that he was a little different. While others were tainted and losing their minds, he was as steady as an old dog; others were frantically testing the edges of the rules, and he chose to lie down; while others racked their brains for survival, he... He seemed to be disliked by the copy? Bite! Abnormal mental threshold detected, bound talent: absolute sanity (passive)] [Absolute Sanity]: Your Sanity value is locked at 100/100 (the upper limit is unknown), and mental pollution is ineffective against you. Cost: You may be too calm, causing some beings to think you are boring, and even... Want to find some "fun" for you. Reading instructions: 1. Do not read this talent description in front of a mirror. 2. This talent cannot be upgraded and does not require adding points. 3. If a dungeon boss takes the initiative to strike up a conversation, please remain polite and try to change the topic. 4. Your "sound" behavior may be broadcast live, please keep up appearances (if you still have them). 5. The final interpretation of this talent belongs to... Well, probably the copy itself?
