Zhang Tie learned a lot of information from Xue Yuxiu.
After hearing that, Zhang Tie gradually aborted his plan of helping the captives of Yin-Yang Sect to escape away before slowly working out a solution to detoxify Golden-Soul Rune Virus for them.
This also proved Zhang Tie's speculation——"His Majesty" would never let those being affected by Golden-Soul Rune Virus escape away. Even if he killed all the crew of the airboat and saved them, if these people didn't receive the sacred sacrifice in half a month, they would die for sure.
