Should he recommend a novel with the male and female protagonists being the Demon King and the King of Gods from the same world?

The big shot knew that this was the book, but he couldn't remember the title. He knelt down and begged for the title.
General content: The male and female protagonists were both gods of creation in their previous lives. They were both men. The male protagonist's previous life had destroyed the female protagonist's previous life. Later, for some reason, the female protagonist's previous life died, leaving only a remnant soul. The Heavenly Dao (I think it was called Qingxuan) sent the remnant soul of the female protagonist's previous life into the body of a genetically modified baby. After the female protagonist grew up, she was trained as a war machine. Later, for some reason, she went to the male protagonist's world and overpowered the original King of Gods. She became the King of Gods herself. At the end of the book, the female protagonist died together with the villain who created the genetically modified baby, but she did not die. She returned to the body she had when she faced the tribulation (it was the White Fox Princess in her original world) and spent the rest of her life with the male protagonist.
In the beginning, after the female lead settled her matters on a planet invaded by the Zerg, she accidentally fell to her death. She was bound by the system, transmigrated to another world, and completed the mission. The Heavenly Dao was the mastermind behind the scenes.
Also, the female protagonist has spatial abilities. After a few worlds, she will be forced to lose her memories in a novel world, but she will recover after that world ends (the female protagonist's surname in that world seems to be Lan).
