MTL - Jubo - Chapter 45

Upon awakening, Lu Xuan found himself as an ordinary spirit plant cultivator, tending to an acre of land merely scraping by in the realm of cultivation.

Fortunately, he stumbled upon an unexpected revelation: with each maturing spiritual plant, he received additional rewards.

Harvesting a The Firefly Grass yielded a Golden Sword Technique.

From the Blood-Devouring Vine, he obtained a Purification Talisman.

And the Phantom Spring Flower gifted him a prescription for the elusive Luminous Flame Pill.

Henceforth, he contentedly tended to his own spiritual fields, observing the tumultuous tides and shifts in the world of cultivation.

“Duels and clashes, expeditions into secret realms, immortal fortunes, obtaining mystical treasures… None of it concerns me!”

“I simply wish for peace and quiet to tend to my fields.”

“You’re the Demon King?”

In response to the woman’s voice filled with murderous intent, the man opened his mouth.

“No, I quit that?”

※ Demon King & Hero will show you the absolute limits of chaotic storytelling.

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?
