My mother is the sweet, silly, and innocent protagonist of an angsty novel.

My mother was the substitute for the overbearing CEO’s unrequited love interest who ran off when she found out she was pregnant.

As for me, I’m nothing special. I’m just the child prodigy who became a hacker at the age of five.

…

Genius hacker Gu Chu found herself reborn in the pages of a tear-jerker book.

She had been transformed into a cute little five year-old. Her mother was the tragic female protagonist while her father was the uncultured, boorish male protagonist. There were also a gaggle of hostile, opportunistic relatives and a pretentious, seemingly-virtuous but vile-hearted aunt...

Gu Chu straightened her small little frame and began waging war secretly to help her mother.

What bad intentions could a five-year-old have?

She just wanted to protect Mama.

…

Until one day...

The man who had hunted her across half the globe in her previous life suddenly appeared.

As he stared at the weeping little doll-like child in her princess dress, the man fell silent for a long while.

There was once an immortal cultivator fighting for the fate of human beings. Unfortunately, he failed that time; but fortunately got another chance as he was reborn once more as a human, on the earth of 5,000 years ago. With a second chance, he not only would embark on the road of saving all mankind, but also would retrieve his human nature on the new journey that would last for 5,000 years.
