The peace did not last long. After the passing of Shan He, the once Glory Empire collapsed. Various forces of Human fell into a long period of wild war for the Divine Weapon Catalogue, but the catalogue was lost during the war.

Human soon lost a large portion of their territory. At that moment, a mysterious hero suddenly appeared on the battlefield. With a legendary Divine Weapon in hand, he severely injured Fen Tian and forced him to retreat.

On his first business trip, Chang Yuan was seated next to an absolute beauty.

He was prepared to have a passionate love life and end his boring single life.

However, he never imagined that their plane would crash and they would be stranded on a deserted island!

As he looked at the vast ocean around them, Chang Yuan wanted to cry.

The silver lining was that the beautiful woman had grabbed onto his clothes and was also stranded here.

Chang Yuan mumbled, “Wait a minute. I suddenly realize that you look very similar to a certain celebrity. What was her name again?”

“Is it Qiao Yuran?”

“Ah, yes. You look like the superstar, Qiao Yuran.”

She replied, “I am Qiao Yuran.”
