Notes on the system: 1. From the day I bound the host, I felt that something was wrong, but I couldn’t find the source of the problem. 2. The feeling of something wrong was getting stronger and stronger, but I still couldn’t find the source of the problem. Where. 3. Is there something wrong with me? Otherwise, why haven’t I received the signal from the main system? 4. Depressed, I no longer try to make the host do the task, but think about how to fix myself , and then suddenly discovered that my host has a super large laboratory! 5, I saw a lot of things in the laboratory that I had never seen before, and... the core of the main system. 6, I finally understood, I also seem to have found the source of what's wrong, but... the notes stop abruptly.
