Find a novel that I have read before, you know?

According to your description, this novel is probably a martial arts from the earth. This is an online novel, which was later adapted into a book. The plot is roughly as follows:

The hero, Cheng Bainiang, came from the earth and was transported to the ancient capital town of the overhead world through an ancient relic experiment. There are different forces headed by different princes, among which the princes of Wang are the truth behind Cheng Bainiang's life experience.

Cheng Bainiang learned that she was the illegitimate child of Wang Fengchen. Before her father died, she got the Guiyue token, which is a key prop for identity authentication and inheritance. After Wang Fan's death, Cheng Bainiang began to pursue Token, trying to regain the right to inherit the throne from Guile.

In the process, he fought against members of different forces, including Queen Alicia and her gang members. Alicia wanted to destroy Guile's Moon Palace with a token to avenge the king's betrayal. She set up tight encirclement, and Suzaku, one of Cheng Bainiang's followers, was persuaded to betray Cheng Bainiang and took the Token.

The follow-up story revolves around Cheng Bainiang's recovery of Token in Guile Moon Palace and her right to inherit the throne. There are many big struggles and changes between roles in the process. In the end, Cheng Bainiang regained Token and became the new king of Gu Lieyue according to the ancient oath, thus eradicating the plot to subvert the ancient capital.

It seems that the description really conforms to the plot and content of Legend of Wulin. I hope you will continue reading this novel! If you have any other questions, just ask me again.
