Death After Death - Chapter 177: Silent Study

When the queen of acting Tan Ruo died, she discovered that she had actually transmigrated into the daughter of her arch-nemesis, the top idol Ji Mo. What’s more, her arch-nemesis’ wife was actually her fan! This was simply outrageous!

Fortunately, after an awkward period of adjustment, facing her mom who had been a fan since her acting debut, the little queen naturally called her “Mommy”. However, facing the former arch-nemesis Ji Mo… sorry, no thanks.

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?
