Douluo's Example Is Perfect

I read a lot of fan fiction and then want to write it myself. Please criticize and point out any shortcomings. 1. The main character's unsystematic martial spirit does not have a particularly impressive training speed, so he occasionally uses cheats from the original work; 2. Do not join the group, enter the Wuhun Palace, or worship the master. There will be some intersection with the original characters but not much; 3. Do not destroy the original CP; 4. Some background settings have been modified from the original work, and the original book shall prevail.
