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.

As soon as Zhao Huai opened his eyes, he realized that he had become the last crown prince of the Great Yan Dynasty. However, he wasn't excited about it because the Great Yan Dynasty had already perished. In the current world, the New Dynasty reigned supreme. He had fled south and settled down, becoming a small pawnshop owner. From being the crown prince of the Great Yan Dynasty to an unknown pawnshop owner, the only thing Zhao Huai could rely on was a golden copper coin he received when he first transmigrated here. By flipping the coin, he could receive instructions in his mind, know the outcome of things, and predict the fortune and misfortune he would face.

In front of you is a mysterious ring. Do you accept it? The instruction you receive is “fortune.” You accept the ring and obtain the destiny of “Good Fortune.” In front of you is a marriage proposal. Do you agree to marry her? The instruction you receive is “misfortune.” You choose to marry her and obtain the destiny of “Divine Insight.” In the chaos caused by demons and monsters in the Central State, you have achieved great cultivation. Do you want to emerge from seclusion? The instruction you receive is “fortune.” You defeat the demon lord with a single sword, shaking the world, and obtain the destiny of “Sword Saint.”

As the New Dynasty was established, its foundation was unstable. Demons and monsters caused disturbances, and people's hearts were unsettled. The world was filled with countless bones, and small countries were on the brink of collapse. Foreign tribes on the border were watching closely. Even in this prosperous era, there were countless plagues. This was a world where cultivation was revered, and Zhao Huai knew that only by becoming an immortal could he protect himself. While the former officials of the Great Yan Dynasty were searching everywhere for the heir of the former dynasty, attempting to restore the nation and continue the imperial legacy of the Great Yan Empire, Zhao Huai said, “Restoring the nation? It'll not be too late for me to do that after I become an immortal.”
