This token was given to him the first time he met Shi Caiming.
This token represented the authority that the headmaster of Wuda granted to Li Fei, allowing him to directly mobilize the Wu'an guards and access many secret archives.
In addition, this token had a defensive function, with a Sword Intent attached to it by Shi Caiming through divine skills (as detailed in Chapter 81 of Volume 2).
Later, when Li Fei was bestowed the title of Marquis and returned to Wuda, given his tendency to stir up trouble, Shi Caiming enhanced the token, imprinting a portion of his Martial Arts Domain onto it!
Just as Xu Jing had separated a portion of his Martial Arts Domain for the New Heaven Association, allowing You Ming to carry it into the Tianshui Tomb to kill Li Fei.
Shi Caiming similarly sealed a portion of his power in this token to give to Li Fei for protection.
