Naruto: Wooing Tsunade from Day One! - Chapter 44: The Start of the Second War

It has been a year since Li Fuchen lost his “talent”. Now he lives the life of a wastrel, being bullied and beaten by those who were once inferior to him. However, he has still not lost everything as he is engaged to a strong and pretty girl of a powerful family… but that came to an end as the engagement was abruptly anulled. With shame brought to the family and his life engulfed by darkness, a ray of hope pierced through the sky.

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.

After the 25th failed blind date, Chen Ji learned from the pain and decided to take the initiative to find a blind date on a public account in the same city.

The official account is very powerful, and I recommended four girls to him:

The first one, female, human, 28 years old, doctor, lived in the apocalypse four months after the sun went out.

The second one, the Nine Realms Human Race, the Empress of Destiny, fell asleep for 100,000 years after being invincible.

The third one, the daughter of the sheriff, is an ancient lady who is good at embroidery and loves poetry. She claims to have written a sequel to “Dream of Red Mansions”.

The fourth one, the descendant of the god, the saint of light, exudes a black aura all over her body, her limbs are twisted, and she is locked at the bottom of the church to pray devoutly.

At first, Chen Ji thought they were playing role-playing, but he didn’t realize until later——

“No, are you all real?”

“How does this allow me to meet you on a blind date?”

“I just had a blind date, how did I save the world?”
