Ultimate Grandmaster

Please ignore the title of the book. I give up writing normal fantasy. This book focuses on daily life, with occasional upgrades to fight monsters. Just treat it as a daily piece of writing! Please don't use your brain when reading a book (brain is a good thing, but unfortunately you don't have it, and neither do I). I don't use my brain to write books. What kind of brain is needed in daily life. Again, ignore the title.
