Why use US dollars instead of firing a gun? Because the power of US dollars is far greater than a gun, Gao Yang brandished green dollars all the way, invincible indeed.
Major Kucher personally came with the convoy, that's the benefit of Gao Yang paying an extra one hundred thousand US dollars. One hundred thousand US dollars is not a small amount, most people in the world will never earn that much in a single go, but Gao Yang gave it away just as a greeting gift. For Morgan and Grand Ivan, this amount is nothing, but for many people, it's enough to make them sell their lives, let alone merely make a trip in person.
After Kucher jumped out of the car, he first shook hands with Gao Yang and the others, then picked up the walkie-talkie and shouted: "Get moving quickly, take turns to load the car."
