The structure of this introduction is very clear, and it progresses layer by layer, gradually amplifying the protagonist's ability and influence:
The Beginning (Part 1): Settings, cheats and initial world
Introduce which world the protagonist travels to (the nautical world), which is a popular IP background.
Provide the first golden finger/opportunity (apprentice Shigetsuki Koushiro and gain heaven-defying understanding). Incredible understanding is a common "talent flow" setting, which means that the protagonist can learn everything quickly.
Mention the acquisition of initial abilities (breathing of all things, the realm of swordsman, easy to capture).
Introducing the second and more important cheat (complex chat group). This is a typical "Zhutian flow" or "chat group flow" setting, paving the way for subsequent absorption of various abilities and character interactions.
