I recommend a book written by a real friend.
Book Title "I Can Become Stronger By Solving Cases"
Fantasy and high martial arts, crime-solving upgrades.
The protagonist travels to a different world and becomes a young detective. As long as he solves the case and arrests the criminal, he can obtain good deeds. The good deeds can be used to open treasure chests and obtain martial arts skills in martial arts novels.
I have read a few chapters and I think they are pretty good. If you are interested, you can read it. The number of words is still small, so it is a good time to invest.
The introduction is below——
In this world, there are martial arts sects that dominate the world and control the life and death of all people; there are knights and knights who use force to break the law and treat human life as nothing; there are monsters and monsters that cause harm to the world and make it difficult for all living beings to survive...
In this case, let me, Yi, sweep away all the evil in the world and wipe out all the injustice in the world!
