Although Long Tao did not find out who Chief Guard Ye's disciple was at the Guard Ye Banquet, he had exchanged contact details with Liu Jie.
After giving it some thought, Long Tao decided to call Liu Jie to see if he would be able to contact Lin Yuan or ask him if he could settle the matter personally.
Since the disciples of top and veteran factions were trying to gain Lin Yuan's favor, someone with status as high as Lin Yuan's should make a statement that could place a lid on the matter.
Frankly, Long Tao did not want to call Liu Jie just because of Black but because of Lin Yuan as well.
Lin Yuan had the Order of Radiant Light and would eventually compete to become one of the Radiance Envoys.
If this incident ended up painting Lin Yuan as someone who was overly aggressive, his road to becoming a Radiance Envoy would be an isolated one.
