The moment Metal King Kong died, his underlings crumbled. With the long ranged attack by Lin Wei and An Hun Group's assassins as well as the help of Qing You and Gu Nian within the distance, all of Metal King Kong's men died shortly.
It went according to Yun Jian's initial wish. All of Metal King Kong's underlings were killed except one who was kept alive.
It was only then Lin Wei and Snow Eagle rushed here with An Hun Group's assassins.
Watching Yun Jian kill Metal King Kong, Cai Lin and others saw the man use Yulong Mainland's spiritual power before his death. There was an abrupt glow that appeared on Metal King Kong's hand just now but before it could fully grow, Yun Jian had killed him. That was why the others who stood farther away thought that Metal King Kong was just retrieving something akin to a flashlight.
