Because the new emperor granted a general amnesty, Feng Xuanyi was able to return to Beijing to congratulate him.He wanted to return to his fiefdom, but Ye Beichen made a ten-year agreement with him, so he reluctantly asked Ye Beichen again to grant him a marriage with Shangguan Weiyang.Instead of agreeing, Ye Beichen made Shangguan Weiyang's maid a princess and married him.
Shangguan Weiyang took the opportunity to switch identities with the maid and leave the palace. Unexpectedly, Feng Xuanyi's men were not convinced and ignited explosives with the intention of blowing up the capital.When Shangguan Weiyang was desperate, he saw Ye Beichen chasing after her on horseback, and the explosives turned into fireworks blooming all over the sky.
