Tbh this show was amazing! I feel like the mission was accomplished though not in the way everybody wanted but think about it. What I understood from this drama is that every character was yearning for their own version of Nirvana but it will cost you something that you hold dear. From the beginning that is 20 years ago, both the brothers wanted something but fate would not allow them to get what they wished for. The Emperor wanted his father's love and acknowledgement but at what cost? His nirvana was his father's love and getting the throne was his wicked way of having something common with his dad on the other hand, Prince Qi wanted to live like a commoner but at what cost? Pei Yan's mother wanted power so bad but at what cost? Pei Yan wanted Jiang Ci's love in his wicked obsessive way but at what cost? Jiang Ci's kind of nirvana was to be free and roam around the world but it sadly later cost her so much loss and my guy Xiao Wuxia, (may you rest in peace) wanted to free his people from slavery and clear his father's name not knowing that his enemy is the Emperor. I feel like my guy won; the people of Yueluo were freed, Jiang Ci is free doing whatever she wants and got to the truth that he most wanted...THIS WAS HIS NIRVANA! In my opinion, it's not a sad ending but a realistic ending. Just think about it...What would have happened to Jiang Ci if the emperor or Xiao Wuxia stepped out of that temple alive? What of Yueluo people? This was a well played match...CHECKMATE EMPEROR!!!
