Great Sage? Are You Sure It's Not Exclusive to Japanese Comics?

Newcomer, new book, I couldn't stay in 996 anymore. I took a rest at home and found that there was nothing I wanted to read, so I decided to write one myself. The system is the great sage system from the Japanese comic Crossing Long Aotian. I found that not many people use this system. I usually read Japanese comics and found that this thing is very useful. Overall, I want to write about The Wandering Earth, but I am a liberal arts major, so the setting is to travel to Harry Potter and the Wandering Earth to see if the mage who has obtained the Great Sage System can save the world together with his friends. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
