Li Yifei had completed several missions in Japan and had even killed the leader of the Yamaguchi Group by himself. It seemed that there weren't many experts in Japan, but during his last mission there, after encountering those high-skilled ninjas, Li Yifei gained new respect for the Japanese masters.
Moreover, after encountering Meng Qianjun and the other expert from when they met the leader, Li Yifei knew there were still many hidden masters in the world, and that his own strength was far from invincible.
Because of World War II, Japan never had an official Special Forces team. The Eastern Kamikaze Special Forces had never participated in various Special Forces competitions before. However, their decision to participate in the most challenging competition this time was indeed abnormal.
