A thousand years ago, Wei Yan was a god-demon feared by all three realms. After dying, he was caught in a thousand-year cycle of reincarnation, and in this life he is a mortal kingdom's crown prince. A prophecy was bestowed upon him at birth: “He who obtains Crown Prince Yan will obtain the world.” Heh! What a tremendous joke. How could the crown prince of a great nation be won over so easily? The world has always been divided, then united, and united, then divided. From childhood, Wei Yan was determined to unite the world one day, so that war and the separation of loved ones would be no more. But fate had other plans. He never expected that when he woke up from a nap at the age of sixteen, his kingdom would have fallen.
