800 years ago, Zhang Ruochen, the son of the Ming Emperor, was murdered by his fiancee Princess Chi Yao, and the proud prince passed away. When he was reincarnated 800 years later, he found out that his murderous fiancee had united the kingdoms to form an empire and crowned herself as Empress Chi Yao. As he stared at her portrait in the temple, a vengeful fire burned within him. "Give me 13 years to cultivate my strength, and I'll send the empress to hell myself."
