Gunmage - Chapter 193: Mage hunting

Master said, the woman I held in my hands, I must protect for the rest of my life.

In Zhenhai City, the Chu Family receives an imperial decree that revives the hope of reclaiming their ancestral title, but only if a descendant places in the top three of the Martial Examination. For young Chu Yangxiang, who unexpectedly discovers he has Grade 1 Martial Dao Talent, this honor seems within reach. Yet, as he rises, envy and family rivalries emerge, with the privileged Chu Xiaoxiang demanding loyalty—or threatening to ruin him. Determined and battered, Chu Yangxiang faces a brutal choice: submit or fight for his family’s legacy. Will he overcome these powerful?

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.

Someone palmed out a blue dragon, which shocked the world. Someone smashes the green hill with a fist, and thousands of people admire it.

Some people live for thousands of years, just like gods. Some people are merciful and compassionate to the world.

In this world of panic, how can there be no place for me?

(The protagonist kills decisively. If you are not a virgin, kill if you have the strength, and if you don’t have the strength, you will die.)
