The Game's Extra: Azhriel Odyssey - Chapter 48: The Battle Royale-2.

Everyone wants superpowers, including Alden Thorn.But even if he's lucky enough to be one of the few humans granted magical abilities by the extraterrestrial System that's been running things on Earth for decades, his goal of being a battlefield support hero is still a long way off.He's got determination on his side and maybe a murderous alien desk clerk, too.The universe is a complicated place. Alden's about to meet it.

I’ve had my fair share of weird wake-ups, but opening my eyes in Black Clover as some no-name extra? That’s a new one, and let me tell you—it’s not exactly the dream reincarnation scenario. Turns out, I’m Sebastian Silva, a guy so insignificant he’s barely a footnote in the series. Oh, and did I mention I’m the father of Noelle Silva and the husband of Acier Silva, the most badass woman in the Clover Kingdom? Yeah, talk about pressure.The kids hate me, my wife barely acknowledges me, and my role in the family is pretty much non-existent. But now that I’ve got my past life’s memories and a second chance, I’m not about to let things slide. With Acier on her deathbed, family dysfunction through the roof, and powerful players lurking in the shadows, I’ve got a lot on my plate.Saving my wife? Reconnecting with my children? Staying under the radar of the Wizard King and some seriously dangerous enemies? It’s not the easiest transmigration, but hey—we’ll live with it.*NOTE: Although all chapters will be written by me, to maintain daily upload, and not lower quality, because I have many time commitments like university, work, etc. Chapter's will be subjected to revision and editing through Grammarly AI.

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.

This novel is also known as Lady Is a Dragon

Five years ago, she left an egg and said, “This is the son I gave birth to you. When he grows up, it’s my return date.” He thought she was joking, but the son broke out of the egg a few months later. She looks like a baby, but there are two shiny, cute and cute little dragon horns on her head, but she has no return date.

*

Later, she disappeared for five years, and he also went crazy for five years, until Xiaolongzai brought back a woman, and he sobered up on the spot… But Xiaolongzai said: “Father, although you don’t have a wife, you will soon have a daughter-in-law. She saved me, and I want to make a promise to her!”

*

Since then, the father and son have fallen into open and secret struggles for favor.

“Your Excellency, Ms. Si’s medical skills have amazed the world, and big shots from all walks of life are fighting to spoil her. Your hero is useless to save the beauty…”

Mo Yinhe suddenly fell to the ground, coughing profusely: “Quick, call her to save me!”

“Your Excellency, the seven rivals who were tortured to the point of death by you are all Miss Si’s own brothers, and they want to take Miss Si back to inherit the throne…”

Mo Yinhe announced his abdication on the spot, and dragged his son to live on the street: “Son, from now on Dad can only follow you to your wife.”

The little dragon cub shook the shiny, cute little dragon horns on the top of his head: “Father, I have already contacted you with a nursing home, so that you can spend your old age safely~”
