The Octogenarian in the City Has a System

How will the life of an 80-year-old man change after he gets the system? Different perspectives and different experiences are all in this book. Ps: This book is a relatively leisurely and comfortable novel with few brainless slaps in the face. After all, the protagonist is an old man. It may be better to read with a relaxed mind. If there are any deficiencies, please point them out gracefully in the comment area and I will consider them and make appropriate changes. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
