Tensei Shitara Slime Datta Ken (WN) - Chapter 306

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?

【Interstellar Marriage】【Strong Men and Strong Women】【Su Shuang Hot Blood】

Lin Fu’s biggest regret is that she was born in a military and police family, but due to physical reasons, she can only sing and dance in the art troupe, and be a qualified vase.

Accidentally traveling to the interstellar era three thousand years later, she was pleasantly surprised to find that she possessed rare S-level spiritual power, and was born to be a fleet commander.

She wants to go to the military academy, enter the Marine War Academy, command the space fleet, and become a heroic female general.

However, her new identity is just the daughter of a farmer in a remote galaxy. In order to realize her dream, she chose to marry the youngest space fleet commander in the empire.

Your Excellency the Commander is cold and abstinent, with an intimidating aura, yet so handsome that it breaks one’s heart, Lin Fu fell at first glance.

I want to eat, but I want to hide it secretly.

Later, people in the whole interstellar world finally knew that the trash bumpkin who had been scolded all the time was actually the commander of the Third Fleet of the Empire.

She is also the most honorable and lovely Princess Freya ever in the royal family, and she is also a frightening star thief.

The entire universe is boiling.

Your Excellency the handsome and noble Commander is not happy: Where is the promised private possession?
