One Piece: God of Space - Chapter 218 Comparison of Strengths of World Governments

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.

Uchiha Natsuki obtained the power system, revived Uchiha, and created the strongest force in the ninja world.

Exclude me Uchiha? Sorry, we quit!

Whoever the garrison likes will go!

“Kakashi, Danzo was the mastermind behind White Fang’s death and was connived by the Third Generation. You actually worked for Konoha!?”

“Itachi, this time I will awaken the Eternal Kaleidoscope for you.”

“Bai, your actual combat ability is too weak. Please enter the Tsukiyomi space to practice for a few years.”

Sorry, we Uchiha have kaleidoscope per capita.

Who can fight in a group fight these days? Get on my shoulder!

Otsutsuki is coming to destroy the world, but you are still striving to be Hokage. There is something wrong with you.

Danzo: “We must not allow Uchiha to gain power!”

“Sir, Uchiha Fugaku has resigned from his position as captain of the Konoha Guard.”

“???”

Third Generation: “The position of Hokage will never be given to you as Uchiha!”

“Hokage-sama, Uchiha has withdrawn from the Hokage campaign.”

“???”

“Sir! Uchiha has established his own country!”

“What!?”

“It’s not rare for us Uchiha to use a Hokage as a treasure. Let’s wait and use him as a target.”

ps: Hizashi did not die simply because he wanted Neji to have a father.

They were left with no choice but to watch the wedding unfold.And it was Evelyn’s time to smirk, for she was now the devil’s wife. And all those who had ruined her, they would pay back in tenfold!++++[Excerpt]“Why would I ditch my husband for a loser?” Evelyn chuckled, crossing her arms defiantly. “He is better than him in all the aspects.” Her gaze drifted to her ex-fiancé nearby, and she continued with a smirk, “Actually, a lot better in bed.”As Annabelle’s face flushed with disdain, Evelyn patted her back and leaned in to deliver another slap. “So, good luck with licking my leftovers, dear step-sister.
