The General's Little Peasant Wife - Chapter 46

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?

As a transmigrator, Zhang Deming discovered that his “golden finger” cheat had absolutely no functions whatsoever!It wasn’t until he saw that familiar line of if-else code that he finally breathed a sigh of relief.As a senior programmer who had literally dropped dead at his desk due to overtime work, Zhang Deming declared: Give me an editing tool, and I can code an entire world—Can’t cast spells? No problem. Keyboards, come to me!The system has no features? No problem. I’ll program them myself!Even in a cultivation world, a programmer can carve out a universe of their own!
