MTL - If You Are Not Red, You Must Inherit the Family - Chapter 25

While on a school field trip in the Czech Republic, Kang Hyuk happens to stumble into a shop called “Archmage.” To his disbelief, the shop is actually owned by an archmage… from another world! Forced to become the Archmage’s disciple, Kang Hyuk is punted into the Kallian Continent, where might and magic overwhelm and wyverns fly high in the sky…

In this world, people are either sword-wielding knights, magic-wielding mages, or spirit-wielding summoners. There hasn’t been anyone yet who can do all three… until now.

Qin Fen had once been abandoned and broken until, one day, he picked up a liquid metal ball that turned his life upside down.
This is the interplanetary era where Classical and Modern Wushu are competing. Classical Wushu enables followers to grow as powerful as dragons and elephants, whereas Modern Wushu enables followers to freeze monsters or even extinguish erupting volcanoes.
Qin Fen steps onto the stage of both Classical and Modern Wushu while belonging to neither. With the exquisite combination of both Classical Wushu and modern technology, he will pave a way to become a legend.
He is one of a kind, a favored son of heaven.

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?
