There are several ways to write a fan magic novel if you intend to add weakness or ability limitation to a fragile and powerful character.

(For example, Kenpachi Zaraki in "Death" is desperate because of his strength, and then seals and limits his strength until he is attacked by quenching.)

2. The old wound has not healed.

(For example, Xue Cun Kiyoji in "The Prince of Tennis" is very skilled, but his dream of winning three consecutive titles ended because of his incomplete recovery after an operation. )

3. Some bad habits

(For example: Gong Jiu in Lu Xiaofeng's legend, a mysterious and powerful behind-the-scenes super villain, but unfortunately he was beaten to death because of greed)

4. Suddenly inspire good ideas

(For example, Meruem, the ant king in The Hunter, was originally cold, crazy and tyrannical, and was infected with human nature under the influence of wheat's character and chess skills).
