Castle of Black Iron - Chapter 1584 - Sharing the Achievements

Humanity was on the brink of destruction. Muyoung, an assassin from the Forest of Death, fell to his knees. There were corpses all around him. For years, he had worked for the Forest of Death and had finally been able to eradicate them. Now, he, himself, was about to die. He closed his eyes as he felt his heart stop beating.

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?

Yun Luo Feng, Hua Xia Medicial School’s genius, died from an accident and her soul attached to Long Xia mainland’s General family’s useless eldest miss.

This waste of an eldest miss not only can’t read or practice martial arts, but is big chested, has no brain, is arrogant and self-willed.

Since having the crown prince as a perfect fiance isn’t enough, she actually snatched a pretty boy in public, leading to the crown prince annulling the marriage.

But she couldn’t stand the annulment and hanged herself.

Opening her eyes again, she is no longer the previous useless miss.

She contracted a God’s puppet and carries a spiritual space. With wonderful hands that can rejuvenate and medical skills that overturn the world!

Both the the royal descendants and nobles above and the merchants below, all compete to curry her favor. Even His Royal Highness, the crown prince,who previously broke the engagement, came knocking on the door wanting to reconcile.

In regard to this, a mysterious man finally couldn’t endure: “Whoever dares to come and harass my woman, let them come but never return!”
