The basic physical rules of this world seem to have been tampered with by a creator who loves to surf the Internet and has a worrying mental state. Logic is a luxury product, the law of cause and effect is an ornament, Internet memes are hard currency, and nonsensicality is the daily code of conduct.
The protagonist does not have any system interface, points, or task prompts in the traditional sense. His "cheating" comes from his innate adaptability to the chaotic rules of this world, and his "brain circuit" that can solve any outrageous event in an even more outrageous way.
The protagonist's strong emotions (especially the desire to complain) will inadvertently trigger the underlying code of the world, making related Internet buzzwords, emoticons, classic film and television scenes, etc. Become a reality around him. For example, when he is angry, a group of "grass mud horses" mythical beasts may really fall from the sky and trample his enemies; when he is speechless, six dots "..." May really appear above his head.
Occasionally, there will be barrages from the "real world" floating in the sky in a semi-transparent form. Most of the contents are "High energy ahead", "The author is crazy", "I will lose if this book is published", etc. Only the protagonist can vaguely perceive it and feel deeply confused.
