Abyss Hunting Ground, Zero Line of Defense

An energy storage formula attracted the transnational evil force Viper to hunt wildly. Retired ace mercenary Lin Xinghe was ordered to escort the inventor when he was in danger, and he teamed up with intelligence elite Su Qingge to escape. From urban street fighting to rural siege, the opponents were well-equipped and viciously deployed, forcing the three of them to death several times. Fighting alone and breaking the situation in reverse, the lone wolf mercenary used his trump card to make a comeback and crush the ambitions of the arms giant.
