While Shi Tianhao and company made fun of Luo Qingwu, like Lin Feng, they knew that Chu Yang is not someone who would show off like a peacock just because he had nothing to do.
Perhaps he had this intention subconsciously. However, to Chu Yang, his purpose for doing so was to further demonstrate his sincerity.
Before the Anti-Celestial Sect War, there was a coup in the Ethereal Mountain Sect. While Li Botao and the rest sought to ally with the Mount Shu Sword Sect, Wu Yunliang, Meng Chaoran and Han Yang were fortunately on the right side. Hence, to avoid retaliation by the Mount Shu Sword Sect, they abandoned their home and followed Xiao Yan, Li Yuanfang and company to Mount Yujing.
Hence, Lin Feng would not short-change the disciples of the Ethereal Mountain Sect.
