Everyone turned to look at Qi Long who was stunned by Yang Mingzhi's words. After thinking about it, they realised that Qi Long was the most suitable person to temporarily take over Ling Lan's position. Most importantly, they believed in Qi Long's character, trusting him that he would not exploit Boss's rightful position.
They believed in Yang Mingzhi and Liu Furong too but after all, they came into Lingtian at a much later time, while Qi Long had been with Ling Lan since he was a scout. He was publicly known as the number one underling of Boss. So, after taking everything into account, he was more suitable for the position than Yang Mingzhi and Liu Furong.
