MTL - Meeting A Demonic Cultivator, Even God Cries - Chapter 136 You are nauseous, you win

As the son of the second generation Hokage Senju Tobirama, and Uchiha Izuna, Haru suddenly had countless complaints in his heart.

However, it seemed like there wasn’t much of a problem

Because Ninja World’s strongest connections had been born!

The first generation Hokage, who has the title of God Ninja World, is my uncle!

The super boss behind the scenes, Uchiha Madara, is my uncle!

Princess Tsunade, you have to call me uncle.

Alas, this damn seniority!

As for me, Senju-Uchiha Haru, I could have been a dandy in Konoha, but in the end, I was forced to unify Ninja World. What should I do?

Fortunately, there were golden fingers…

Sally, in order to fulfill her original wish, entered Beast World and transformed into a little white mouse, also binding herself to the Offspring System.[The Dragon Lineage has gone ten thousand years without new blood.][How many points for the Dragon Lineage?][Five hundred million!]

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?

Expect some:

Cold war era techs.

Super battleship with advanced electronics, propulsion, and fire control systems?

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

Han Yun was spoiled from childhood.

He survived past his emperor dad and crown prince elder brother, and became an emperor.

He didn’t know how to govern the country, but he was lucky—there was a Grand Preceptor who “assisted” him, spoiling him even more than his father did.

After just a few years, this puppet emperor died. When he awakened, he had transmigrated into the modern world, becoming a third-rate model struggling alone without any loving parents.

Just when he thought he had become a little cabbage that nobody wanted and no one would ever spoil him again, a certain ancient monster of a Grand Preceptor who had lived 1,000 years appeared again… and looked to be doing quite well for himself.

The utterly impoverished little emperor had tears in his eyes: “Beloved subject! Zhen (royal We) have missed you so much!”

Grand Preceptor: “Your Majesty, this minister has waited for you for a thousand years.”
