Harry Potter: Dimensional Wizard - Chapter 548: Planar Expansion

Vance is a young man who worked hard to bring his Sword Mage to the top to become one of the best players in all of Alantina Online.

While trying to solo the final boss, Vance dies and wakes up not at a spawn point but in an old rustic room?

“Hmmm? Where is the logout button? No, wait! What happened to my level!?”

With no idea how things turned out the way they did.

Vance must start out from the beginning as the weakest NPC to find out why he was suddenly sucked into the game.

All while surviving in a game that has become more real than the real world itself.

Fresh off the battlefield, Marshal Ke Lian received the startling news that his never-before-met fiancée had faced a family tragedy, losing both her parents. Despite inheriting a massive fortune, she now required someone to look after her.As the top-ranking figure on the “Empire's Most Popular Young Men Among Women” list, Marshal Ke Lian, known for his unparalleled charm and prowess, dutifully followed his father's wishes and married Du Xixi.He had envisioned Du Xixi as a delicate flower in need of tender care. But who could have imagined that the girl wielding a kitchen knife, fiercely battling the Humming Beast, would be the same one needing protection?Du Xixi stumbled into the Star Era, finding herself parentless and with a billion-dollar inheritance to claim... Oh, and a supposedly handsome fiancé she had never actually met.As the sole heir to the prestigious Imperial Chef Family, Du Xixi gazed at the rows of sleek Mecha in her new husband's courtyard and couldn't help but feel that a kitchen knife aligned more with her true temperament.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

PS. Cover not mine, I just found it on google.

Transmigration is the total rage of novels nowadays, and if the main character isn’t careful, they get swept up into the bandwagon, so this is a story from another continent. Magic? —— of course the main character won’t know how to use it, but what about knowing how to use electricity? Dou Qi? —— the main character still doesn’t know, but is inner power more strong? Beautiful women? —— of course the main character has them, or else there wouldn’t be anything worth reading in this novel. How many? —— that question’s quite good, if I told you everything, what would you read for? An honest warning to the female readers and your tastes, it is a harem novel, don’t read it if you’re not interested. A stern warning to male readers and your tastes, um, it’s like a breath of fresh air.
