1. **The ultimate brotherhood running in both directions:** The mutual sacrifices at the beginning establish the strongest emotional core of the book. 2. **BUG level system:** The system does not issue tasks, but only finds loopholes in the world's laws. The gameplay is novel and unique. 3. **Good-for-nothing counterattack + extreme counterattack:** From a bereaved dog with all his cultivation to an overlord who is the enemy of the world. 4. **High IQ game:** The protagonist is not a reckless man, every step is full of calculations, and the game with top forces is thrilling.
