Due to the time crunch, Feng Jun did not notify certain individuals. For instance, his relations with the Siming Celestial Realm were fairly good, but as their Daoist practices were in decline and their influence insufficient, he felt that it would even be difficult for them to purchase a plane ticket. Hence, he did not disturb them.
As for the Maoshan Lineage, he notified Tang Wangsun. However, Tang Tianshi said he was preoccupied with numerous ceremonies at the year's end and couldn't get away, thus he sent his daughter in his stead—Feng Jun felt that the old Heavenly Master was paving the way for the Little Celestial Master.
Regardless, the arrival of Luofu Qingxiaosi and the people from Wangwu Dongtian was somewhat unexpected to him.
