I Became Hades, the God of the Underworld from Greek and Roman Mythology

Liu Ming, since he was young, lived in a savage prison named Savage Island where the prisoners aren’t controlled by any guard or security. When the island sinks due to “mysterious” events, only a handful of people survive – those survivors are then pursued by the government.

On the other hand at another place two practitioners are worrying about what will happen to them because the young master that they were supposed to protect had died.

Their young master looks nearly like our MC
What will happen?

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?

Missiles?
Modern medicines and equipment?
