After returning from rebirth, the protagonist fully understands the principle of "shooting the first bird". He/she takes advantage of the knowledge and information gap in the previous life and begins to quietly collect resources, improve strength, repair relationships, or look for clues missed in the previous life. This stage is the process of "laying the foundation" and "raising the gu". You may encounter some minor troubles, but the protagonist can always resolve them skillfully with foresight and start to accumulate "little cool points".
