The first book I read was... "Sorry, I Cheated"! It was okay in the early stage, but it became outrageous in the later stage. The second book is "My Kung Fu Is All Relying on Picking Up". This book is very good-looking. I have read more than a thousand chapters. It is written by the stand-alone king. He also has a book called "My Kung Fu Comes with Special Effects" which is also very good-looking and very sexy. Well, in short, the previous ones were all fantasy systems...
Strictly speaking, it was the book Fighting to Break the Sky [Chigua] that pioneered the "portable grandpa" setting. It distributed material rewards according to the needs of the protagonist, which is equivalent to a plug-in for the author to reasonably arrange opportunities. The subsequent system text combines the two settings of unlimited flow and portable grandpa: Publish tasks ☛ Complete tasks ☛ Get rewards Publish tasks ☛ Uncompleted tasks ☛ Punish or erase This is a very typical unlimited flow routine, but someone moved the "main god" of unlimited flow into some cool articles instead of "portable grandpa", so there was a system flow [Chigua][Chigua][Chigua]
