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?

When a mountain comes to life, awakening its consciousness, it takes on another form—a Mountain Spirit. And that’s me reborn with extraordinary Divine powers.Want to know what these divine powers are?Well, one of them allows me to accelerate herb growth—up to one hundred times faster! Impressive, right?But wait, there’s more! I also possess a ‘golden finger’—which is ‘Space-Time’ system that lets me fish for lost techniques, weapons, pill formulas, and other treasures from the rivers of time and space.With these at my disposal, I’m sure to become stronger, at least stronger than the beautiful sect master who claims my mountain as her personal retreat and constantly drag me into her matters.It’s not an easy life, but no need to worry! I’m not just any spirit—I’m a human spirit born from a mountain, which means I have an extraordinary talent for cultivation.To top it off, my system was generous enough to grant me a divine cultivation technique right from the start. There’s just one tiny problem: it’s a dual cultivation technique, and I need a partner to cultivate it.So, I had no choice but to convince the sect master’s stunning disciple to help me out. I mean, it’s not like I’m after her gorgeous long legs, her curvaceous thighs, or her… well, you get the point.I’m just a humble cultivator trying to grow stronger by any means necessary.If only she’d run into some trouble, so I could swoop in and save the day. That would make things a lot easier for me… but alas, life is never that simple.Still, I’ll find a way. With my Space-Time system, my mountain’s power, and a little charm, I’ll outgrow this mountain and surpass everyone—even the sect master. And maybe, just maybe, I’ll enjoy the beauties along the way.

A card from another world... the legendary [Blue-Eyes White Dragon]!At age 20... the world was no longer ready for what I would become.My legend begins in the East Blue, but my destination is the heavens.
