The writing is pretty bad, and the ending is rushed.
[No romance]
Wu Yuan transmigrates, but this isn’t what she wanted. All she wants is the truth.
In 1980, Wu Yuan is born. A fortune-teller says she is “short on connections, long on blessings,” so she is given the name Wu Yuan.
In 1984, Wu Yuan moves into the Hong family residence, where she rests and keeps Xie Yuchen company.
In 2002, Wu Yuan meets Zhang Qiling through Hei Xiazi, and the words “the Ultimate” suddenly surface in her mind.
In the autumn of 2002, Wu Yuan fakes her death to escape, finds Zhang Qiling, and learns from him about the Bronze Gate.
In the winter of 2002, guided by Zhang Qiling, Wu Yuan enters the Bronze Gate and loses most of her memories.
[The female lead has had a memory since birth. The person in it is Zhang Qiling. As a child, she thought she was him, until she later met Zhang Qiling through Hei Xiazi.]
P.S. There are many major departures from canon. For a while, the female lead will inhabit the body of a member of the Zhang family, and her gender will change to male. Later, she will return to her own body. Because Zhang Qiling’s memories have influenced her since childhood, she has little understanding of gender and doesn’t care about gender boundaries. There will be no romance between men and women.
P.P.S. A lot of details aren’t written out; only the general situation is explained.
