All the elders of Iron-Dragon Sect arrived at Centralpillar Mountain, including Yan Feiqing, Guo Hongyi, Hermit Mountain Lifting, Lu Zhongming and Lin Huanxi.
Zhang Gui, O'Laura and Zhang Su arrived there too.
However, Zhang Yang didn't come; because when these people were setting for the South Border, Zhang Yang was setting for Heavens Fortune Sect to cultivate for 2 decades in the Dongtian of Heavens Fortune Sect. Zhang Yang had already prepared well for it. As the access of 2 decades to Dongtian was gifted to Zhang Tie by Heavens Fortune Sect, now that Zhang Tie didn't go there, Zhang Yang would not waste the good opportunity.
After all the knights of Iron-Dragon Sect left Iron-Dragon Sect, Fire-Dragon Bounty Territory and Jinwu Palace became boring; therefore, Zhang Yang took his parents and Zhang Tie's children to Heavens Fortune Sect for visiting Zhang Chenglei by the way. Of course, these people were safe in Heavens Fortune Sect.
