Help! I am bound to Aizen! - Chapter 297

Lee Jin Woo once lived a dismal life.
He lived pitifully on a day to day basis in his five-pyeon studio filled with mold.

Then, one day, he died in a sudden fire.

When he wakes up, he finds himself inside a novel.
But there’s just one issue…
He had become the novel’s villain!

After successfully reaching the Core Formation Stage and forming his Golden Core, Bai Langtian was betrayed by his own Master. His core was ripped from his body, and he was thrown off a mountain cliff into a valley full of demonic beasts.Thankfully, he survived the fall, and met his senior sister, Shangguan Yue Ling.She too had been betrayed by the same Master and pushed into this valley ten years ago. Ever since, she had been surviving alone by eating the corrupted flesh of demonic beasts.Now, Yue Ling revealed to Langtian a new path of cultivation:Demonic Cultivation.To reclaim his strength and take revenge, he must consume the flesh and essence of ten thousand demonic beasts.

Beneath the vast and infinite starry skies of the universe, countless tribes engage in endless strife, and the flames of war remain unquenched.Rising from insignificance, he possessed no exceptional talents, except for the ability to draw upon the fruits of cultivation from the future.Yet, in a single night, he understood the Dao, and took a step that shattered the shackles of life.With but a thought, he grasped the universal powers, casually breaking down the barriers between spirit and reality.To him, even the most profound and enigmatic of secret tomes were as simple and dull as children's books.Still, he had to go back and fill in the gaps of his cultivation...Some appeared to be glorious, unparalleled geniuses.In reality, they practiced like mad in the shadows to repay their debts...

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?
