How did Zhang Wuji cure his cold poison?

Jiuyang Zhen Jing was created by an expert who played chess with Wang Chaoyang. Later, Wang Chaoyang showed the expert Zhen Jing's wine seal. After reading it, the expert thought that Jiuyin Zhenjing was too heavy, so he created Jiuyang Zhenjing. Jiuyang Zhen Jing is different from Jiuyin Zhen Jing, which is a pure inner psychology. Buddhism and Taoism are related, which can not only break the negative internal force of cold, but also be spontaneous.
