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.

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?

In the aftermath of a tragic incident, the soul of Zhang Fei was transmigrated into a sacred body in a world of cultivation. Joined by the consciousness of an ancient cultivator, Zhang Fei must find a way to survive in this deadly world of beast demons and immortal cultivators.

Iruma Takumi, a 40-year old salary man, was dragged into a hero summoning just like in a template. What was his fate? The Goddess sent him and the heroes to the other world separately.

With the Goddess’ overprotective support, he landed in a different world looking handsome, rejuvenated, and quite different from a Japanese.

Although he wanted a slow life while working in the manufacturing trade, that was not permitted by the Goddess’ special body and abilities.

Would Takumi be able to live a peaceful life in a different world?
