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.

I was reincarnated as the supporting character of a novel. As a wingwoman in a depressing romance novel titled at that. Romance is out of the question, and the future of my family is ominous because of debt. I was going to become a civil servant to gain some of the splendor I never got in my last life…but the male love interests are acting kind of strange?! “Just think about it, does Shushu look like someone who would blush and act shy?” “Wow…….that would be great.” Cory said as he stared at Hylli in a daze, and Yves frowned and whispered to himself. “Should I just kidnap her…….” Swan wrapped his face with both of his hands and stayed quiet. His face turned bright red. The blush turned his ears red. Why are you guys fooling around, you’re supposed to be obsessing over the heroine. The story of Shuraina West, Shushu’s reverse harem academy survival. Note: Ojakgyo means wingman/woman!

Gray was just a normal guy. No powers. No family. No future.In a world where strength and status decide everything, he was at the bottom.He worked hard just to survive, taking care of his little sister after their parents were gone.But no matter how hard he tried, life never gave him a break.And after losing his only job, Gray was ready to give up completely.Then something strange happened.Just as about he was to end his life, an unknown voice echoed in his ears.[Welcome to the Great Tycoon System.]And for the first time, Gray had a way to fight back.From being weak and broke, he’ll rise to the top—one coin and one job at a time.Because in the world where money can buy power, Gray is about to become the richest and strongest man alive.

In a parallel world, everyone awakened to weapon talents. They used divine weapons to battle against ferocious creatures.

Hence, the Forgemaster job class was born and was held in high esteem.

Wu Mo transmigrated to this world and became a student of the top academy, Divine Arms Academy.

The end-of-semester practical exam was in three days. Students were required to forge a divine weapon on the spot.

However, he was not prepared at all!

Fortunately, he awakened a system which allowed him to see the blueprints of all mythical weapons.

[Mjolnir]

[Divine Bow of the Winter God]

[Eternal Spear]

[Shield of Zeus]

…

Since he was a blacksmith, he decided to create a hammer for himself first.

On the day of the end-of-semester exam, the whole world was astonished!

An examiner exclaimed, “We asked you to submit your assignment and you are submitting Mjolnir?”
