While Harrison was still in a daze, Qin an had already switched to his m4. He poked his head out from behind the rock, opened the red dot scope, and fired a dense barrage of bullets at Harrison!
Hason reacted quickly. He rolled again and shot Qin an's head with his 98k. However, Qin an also had a level three Spetsnaz Helmet!
Under the concentrated barrage of 5.56mm bullets, there was no cover around Harrison. With little health left, he fell to the ground.
It was obvious that if Qin an had not headshotted him with a 98k, he would not have dared to open fire with an m4. That was because Hanson's sniping was very accurate. If Qin an had fired with an M4 from the start, he could have used an instant snipe to hit Qin an's head. Then, he would switch to the M4 to fight with Qin an. In that case, it would be hard to tell who would win.
However, Qin an had already established his health advantage with a headshot, and was already in an undefeatable position.
