The World I Live in - Legend of the Demon Soldier

I feel a little dissatisfied with the ending of Legend of the Demon Soldier, so I want to revise it based on my own experience. In terms of plot, it is actually similar to the original work. It is just for fun. I also feel that it is too boring. I want to write something interesting that I can see. After all, most of the current novels are invincible style, which feels too boring. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
