DEMON CASTLE - Chapter 12

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?

Cold war era techs.

Super battleship with advanced electronics, propulsion, and fire control systems?

PS. Cover not mine, I just found it on google.

Li Xuan traveled through time and had no system or plug-ins. He could only live in a small mountain village temporarily. However, one day, he was mistaken for a hidden master and he had to become his disciple.

As an upright person, Li Xuan didn’t want to lie to others and sternly refused, but the other party offered him too much, so he had to make up a set of training methods to fool him–as a result, the apprentice succeeded in practicing!

Looking at his disciple with thunderous muscles and strong blood, Li Xuan was stunned: “I made it up, how could I succeed in cultivation? What kind of monster are you?!”

At this time, Golden Finger appeared: “Your apprentice has started to practice the exercises you made up, and you have directly mastered the exercises, and your strength is a hundred times higher than those in the same realm!”

ps: The book “I’ve been at home for a hundred years and I’m invincible when I go out” has been ordered with a high order of 20,000 yuan. If you find it interesting, you can go to the old book to read it ^_^
