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?

Yang Feng somehow transmigrated into a different world and received a legacy of an ‘ancient high tech’ family, which does not directly raise his power, but gives him the technology to build things which are way more advanced than the seemingly medieval world.

Somebody once told a joke.A man ran in place all his life. He worked a job he didn't love for people he couldn't stand. But at the end of the day, the number in his bank account went up.That man got a second chance at life. He woke up in another world, full of adventures and romances and monsters and gods. And floating above his head he saw the number “1”. So what did he say?“Gosh I better make the number go up.”Not today. Not for this old soul. Reborn as a beast of battle meant to live a short life and die screaming, Garek refuses. He puts the madness of skills and levels behind him and sets out to found a little farmstead. He grows crops. Maybe someday he'll get a pig, and have bacon.It's a shame the world won't let him be. It's a shame that the warmongers and level-grinders hate nothing more than a soul at peace.He put down his sword for a plowshare, but when trouble comes calling, he'll pick it up again.
