If everything could come back

This is the continuation of the tvb drama "The Legend of Double Dragon of the Tang Dynasty", and has nothing to do with Huang Yi's original work!It mainly writes the love story of Kou Zhong and Song Yuzhi.After watching the ending of the TV series, I was unwilling to end like this, so I came up with this follow-up idea!What if everything could start all over again, change Kou Zhong's fate of going to death, and allow him to become king and unify the world?
