(I recommend checking out The Journey Through Worlds Begins with Empresses in the Palace and The Path to Godhood Without Cheats in the Multiverse. Try starting from Volume Four.)
(A multiverse story: the System sets her up, she loses her memories after transmigrating, and she and her nemesis become lovers!)
Lin Qingqian is a walking disaster. The Demon Venerable Xuan Ye from Immortal Samsara gets tangled up with her, and the Heavenly Dao of Immortal Samsara strikes her with one thunderbolt after another, knocking her out of that world. Then Xuan Ye fights the Heavenly Dao of Till the End of the Moon, and Lin Qingqian gets kicked out of the world again. She and the System battle it out in Empresses in the Palace, but the System tricks her into transmigrating and losing her memories. As a result, she and her nemesis end up engaged.
The black dumpling System suppresses them, hoping to break their will and devour them both. Midway through, Lin Qingqian regains her memories, sees through the System’s scheme, and devours it. At the last moment, the System self-destructs and curses Xuan Ye, who is still suffering from amnesia!
So when they transmigrate into the world of Eternal Love, Xuan Ye is still amnesiac and transforms into a chubby toddler. He had planned to pursue Lin Qingqian as his perfect self and make wonderful memories of love with her, but... No more talk. To keep them from turning into siblings instead of a couple, Xuan Ye gives it everything he’s got!
Lin Qingqian insists her memories are right.
“Ahhh, this is so awkward! My amnesiac nemesis is trying to court me!”
“Great, Xuan Ye has turned into a chubby toddler! I don’t mind this kind of courtship. He can come on even stronger, because he’s just too cute!”
Next, they transmigrate into the world of Ashes of Love. Xuan Ye and Runyu become fraternal twins. At this point, Xuan Ye is a pure-hearted romantic who loses his memory for eight hours and falls in love with Lin Qingqian, as well as a troublemaker who regains his memories after eight hours but can’t remember anything from his amnesiac period.
The first volume is not good, but the second volume is good. The second volume is okay. Xuan Ye, who was cursed by the system and turned into a three-headed body, interacts with the heroine in a funny way. However, the best one is the author's "The Road to Becoming a God Without Plugins" written by the author. I recommend the fourth volume of Lotus Tower. The author must be inexperienced. The early writing is not good, but the later stage is good.
It looks good, but Xuan Ye's father is a bit weak.
