The Ugly Queen Season 2

Continuing the plot of the first season, it follows the story of Zhong Wu Yan, who has given birth to a "freak" prince, and King Qi imprisons her in the cold palace. Their relationship evolves from indifference to reconciliation until they find love again.
The Spring and Autumn Period and Warring States Period were a time rife with war, and people struggled to survive. However, the King of Qi abandoned his duties while his Queen, Zhong Wu Yan, was thrown into the cold palace. As time passes, the King becomes more and more enamoured with Xia Ying Chun. He also misplaces his trust towards Wei Wen Bin, a surrendered general who was once an enemy.
As it turns out, Wei Wen Bin and Xia Ying Chun have been plotting a rebellion, and it is thanks to Zhong Wu Yan's foresight that she was able to save King Qi. King Qi regrets his actions and releases Zhong Wu Yan from the cold palace, but with her son still missing, the two can never truly reconcile. Meanwhile, Wei Wen Bin and Xia Ying Chun have not given up on their plan to destroy the state of Qi, even instigating the King of Chu to start a war. To save the people from another bloody battle, Zhong Wu Yan commands an army to fight for her homeland.
