A forbidden ritual performed in the central ancestral temple to alter heavenly destiny, exchanging the fates of two people so that Heaven itself will reveal Xianzhu as the true Princess Yu Xian'er. It requires the White Dragon Jade, the sovereign's blood, the substitute's blood offered to the jade bi and to Jing Zhonghua's memorial tablet, and the willing consent of the one taking the new identity. The ritual succeeded, causing the Dragon Jade to crumble to dust, and caused Yu Sangsang's soul to drift from her body, after which she coughed up blood.
