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?

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

As soon as Lu Xuan woke up, he became an ordinary spiritual planter in Sanxiufang City, guarding a one-acre three-point spiritual field, and living in the world of practice.

Fortunately, I accidentally discovered that every time a spiritual plant matures, I can get extra rewards.

Harvest a sword grass and get a sword pill.

Harvest a Xuan Chong vine and get a share of Yin Xingsha.

Harvest a Youquan flower and get a piece of Zhiyan Pill Recipe.

…

From then on, he guarded his spiritual field peacefully, and sat and watched the world of practice turbulent and vicissitudes.

“What about fighting skills, exploring secret realms, seeking immortal fate, obtaining magic weapons…all have nothing to do with me!”

“I just want to farm quietly.”
