Toaru Majutsu no Index: New Testament - Volume 17, Chapter 2: Or Escape Provides a Counterattack - Social_Network_Slayer.

Sakimori Kagami plays a VRMMORPG called Arch Earth Online. He is a veteran player with the name and appearance similar to an elderly bearded wizard from a certain book about a ring.

One day he purchases an appearance change item as a last resort to spend expiring currency and gets the idea of choosing what he would want to look like if his character was ever a girl.

Falling asleep should have suspended the game, but Kagami wakes up still online and feels the game has has gotten a bit more realistic. Did Arch Earth Online finally get a long-awaited update?

This is the story of a boy who lived a secluded life in the mountains, tending his farm, rearing his fish, and dreaming his dreams. Eh? Did I suddenly conquer all worlds and become the big boss? Or am I still in a dream?

Su Ran, a music prodigy, woke up transmigrated into a book.

At that point in time, the main story arc in the book had already been completed. As a villainess female supporting character, not only did she need to take over the original owner’s pitiful life in poverty, she also gained an instant son right at his rebellious period.

Ten or so more years from then, the son would turn into a twisted, evil villain. He would appear in one of the extra chapters to pick on the male and female lead’s children.

Su Ran: Son, you shouldn’t be too outstanding.
Su Han: Why not?
Su Ran: ’cause you will be killed.

Su Ran: Son, would you like to learn music from me and become a zen, little fairy boy who only needs to drink dew.
Su Han: No, I want to go into business so I can support you.

- Description from Novelupdates

On the way to a company workshop, we fell into a world of immortal cultivators while still in the car.

Those with spiritual roots and unique abilities were all called to join cultivation sects, living prosperously.

But I, having neither spiritual roots nor special abilities, lived as an ordinary mortal for 50 years, complying with fate until my death.

That’s what I thought.

Until I regressed.
