The Chronicles of the Immortal God - Chapter 6: Innocent Master

One day when I was working as a low-ranking civil servant in a hopeless imperial palace department, I realized that I had reincarnated in a novel.“Oh my god, the villain is about to start a war, right? If a war breaks out, people like me will be the first to die!”An imminent war as per the original setting.If I want to live, I must first save the crown prince!To save the crown prince who dies first in the original story, I leaked the original’s information to catch the villains.Suddenly, I became the youngest minister.I didn’t really mean to get ahead, but there’s nothing wrong with that!Let’s just catch the villain.* * *It’s a lot of fun to ab*se the villains, and the taste of power is also very sweet.However…“His Highness the Crown Prince has a great sense of responsibility, but since he has nowhere to focus, he may want to run away sometimes.”The strange new intern is talking nonsense.No, how did I save the prince!“What? Run awaaaay?”With a glint in my eyes, I said grimly.“If His Highness runs away… I will personally chase him to the end of the continent. I will somehow drag him by the collar, stick tight next to him, and keep an eye on him.”Hmm?But intern, why are you shaking? Why are your ears red?

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?

Living things really are ignorant – the greed to obtain the key to knowledge and the fundamentals of energy overpowers them. Little do they know that knowledge is full of lies and energy is the root of destruction. Us, mages, have mastered travelling through space and time. We are invincible, we can turn worlds into dust and you, mere ants, will be wiped out with no trace.
