Lin Mo was originally an ordinary social animal. Accidentally obtained a piece of core code from the "old archive". He has a calm personality and complains about being obedient. He is forced to understand the world from a "programmer's" perspective and is good at exploiting loopholes in the rules. The goal gradually changed from "self-protection" to "exploring the truth" and "protecting the people you care about."
Lin Mo discovered that the "system" did not come from the future or high-dimensional civilization, but from an old version of the world line that was "deleted". It was a string of [world source codes] on the verge of collapse.
