When they said within an hour, it meant within the hour. At the fifty-ninth minute following the attack, the people Mr. Smith had sent finally arrived.
That is, shortly after Renato and Lavrent went in to negotiate, the reinforcements dispatched by Smith arrived. They came fully armed, and although their attire wasn't camouflage but tactical gear, everything else was equipped to battle standards. In terms of firepower, they were much stronger than the previous armed security because they even brought machine guns and grenades.
Then Renato's core troops also showed up, led by a fierce-looking man with four or five others. Although they were in plain clothes and didn't display their weapons, it was clear these were the lieutenants Renato truly trusted.
Nothing more needed to be said, and there wasn't much left for Gao Guang and his company to do.
