I wonder what poison Guanshan Ningyuan was poisoned by?

The poison of pulling machine. Ning Yuanzhou was poisoned by a tractor in "Crossing the Mountain in a Moment", and Zhang Song forced him to take it in order to contain him. In order to protect Ruyi's identity from being discovered, Ning Yuanzhou asked her to hide in the dark, and then went to the rescue with Yu and others. But the assassin was wearing soft armor's clothes, and Ning Yuanzhou was poisoned again, so Ruyi had to show up to help. Ning Yuanzhou was in a coma. Ruyi took him to Zhao Qian for treatment, but Zhao Qian could do nothing. Ning Yuanzhou woke up after drawing blood, and told Zhao Qian to plant the reincarnation flag in Anguo Zhou Jun to let people in Zhang Song know the situation here. Ning Yuanzhou apologized to Ruyi and gave Ruyi the candy in her arms, hoping that Ruyi could eat a candy when she was unhappy in the future. Seeing that Ningyuan boat was in danger, Li Tongguang didn't want to hate himself, so he took out Shaxi's restart Dan to treat Ningyuan boat.
