Gu Nan and Jun Jinghao unexpectedly died in a secret realm. Fortunately, the spirit Lingxi of the space realm came to their aid, pulling both their souls into the space at the last moment and allowing them to survive.
In the process, Gu Nan's soul suffered a second injury and became incomplete, due to her younger sister's jealousy and the soul-swapping that had stolen her marriage years ago, as well as the secret realm's explosion. Jun Jinghao, whose soul was originally a fragment reincarnated, could not remain conscious, so Lingxi sealed him deep within the space.
Afterward, Gu Nan, with her damaged soul, discussed a plan with Lingxi. She would bind herself to the System sealed within the space and travel through three thousand worlds, searching for fragments of Jun Jinghao's soul while earning soul power, merit, faith, and other energies, along with various rare treasures. She would use them to repair her soul and restore her body.
Fortunately, Gu Nan found an opportunity in the first small world she entered. There, she signed a growth-type soul contract of heaven and earth with the reincarnated soul fragment of Jun Jinghao, laying the foundation for their later legendary journey through the three realms: crushing scum, searching for loved ones, building businesses, and hunting for treasure.
It's too long and too slow to enter the main drama. Not many people have the patience to watch long plots now... I'll simplify it and spread it...
It seems okay, but why is it at odds with the real and fake daughter?
It's okay. It would be even better if the heroine gets married and has her own children.
