Is this really a Game?! - Chapter 930 The Flood Dragon’s True Power

The weak cry out with all their might, yet no one cares; The strong whisper softly, yet their words penetrate deeply into the heart. A Talent Tree ablaze with flames, every leaf bearing different spirit runes, Lu Ye, reduced to a mining slave after his sect was destroyed, used this to become a cultivator and stirred the winds of change in the Nine Provinces...

After the soldiers’ mercenary group where he used to work had been utterly destroyed, Loren, who survived the disaster, decided to walk the adventurer’s path as a way to make a living. However, for Loren who had no acquaintances and nothing but an empty pocket on him, receiving a single quest seemed like a faraway aim. So, as he was contemplating about what he should do next, another adventurer called out to him.

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?
