"Then you may begin now," Feng Simei took out the Fire Dragon Pill and handed it to Dugu Qianye.
Dugu Qianye received the elixir but did not immediately administer it to Dugu Yunheng; instead, she drew out a knife as thin as a cicada's wing, scraped clean all the necrotic flesh from Dugu Yunheng's wound, and infused some Chaos Qi to envelop his heart. Only then did she feed the Fire Dragon Pill to Dugu Yunheng.
Even this step took over an hour. After she had Dugu Yunheng swallow the Fire Dragon Pill, she observed his condition from the side.
The Snow Cold Pill is an extremely cold elixir, while the Fire Dragon Pill is fierce in nature. The two clashed violently inside Dugu Yunheng's body, waging a fierce battle. The torment of being caught between fire and ice probably felt just like this.
