SpiderGwen: I have a system?! - Chapter 67 - : Short Timeskip and Teaching

After a god screws up and accidentally takes high schooler Shou’s life, he offers him reincarnation with a gift to make up for it. Shou asks to retain all his old memories for the new life. Shou is reborn as Will, a noble’s son in a world where magic use is common and involves knowledge of kanji characters. With all his memories, he’s a brilliant toddler, and when he experiments with magic, he finds that he has an amazing talent for it! What’s more, though he was smart but unloved in his old life, in his new life he has a mother and a father who both love him deeply. His future as Will is looking very bright and cool!

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.

Xie Jingyuan, the master taoist of Qingxu Temple, was reborn into modern times together with the cat demon Su Miaomiao.

Su Miaomiao: That classmate’s dried fish seems delicious.

Xie Jingyuan: I’ll buy one for you, don’t steal it.

Su Miaomiao: It’s raining, Taoist Priest, come here and pick me up.

Xie Jingyuan: I’m busy.

Su Miaomiao: It’s okay, a male classmate is willing to drop me at the dormitory.

Xie Jingyuan: … Send me the location. ·
