The plot of the first season of " Celebrating Years " revolved around Fan Xian entering the capital and his diplomatic mission to Northern Qi. The Qing Emperor had laid out a scheme for more than 20 years. He captured Xiao En alive and brought his grandson back to the Qing Kingdom, promising to nurture him into a Qing soldier who hated Northern Qi to the bone. As part of the Qing Emperor's plan, Fan Xian was sent to Northern Qi. His goal was to use this opportunity to get Xiao En's secret about the Temple. However, the Qing Emperor's plan was not limited to this. There was another person hiding behind the scenes making an even bigger plan. In the ending of the first season, the diplomatic mission set foot on the road back. Fan Xian learned that the Eldest Princess and the Second Prince had joined forces behind the palace treasury smuggling case. The Second Prince was the " mastermind " hidden the deepest in this court dispute. After that, the diplomatic mission was surrounded by a group of mysterious cavalry. Fan Xian was stabbed by Yan Bingyun, causing suspicion and discussion in the audience. This ending was known as the " God-level reversal ", and it triggered a heated discussion on the Internet and voices that were looking forward to the second season.
