Large trucks turned around and drove towards the tunnel, and it was very difficult for a convoy of nearly 100 mixed military vehicles and trucks to turn around and enter the tunnel within two minutes.

The convoy Fang Gang drove not far away, and a military vehicle at the beginning had just entered the mouth of the tunnel, and two black spots appeared in the distance, and more than ten seconds later, two mutant big black birds were circling above everyone, they did not leave more reaction time for the convoy below, and leaned over towards the convoy below.

"Tata Tata ......" Zhang Xiaoqiang clasped the trigger of the 12.7 mm anti-aircraft machine gun and continued to squirt hot bullets at the big black bird that swooped down into the sky, at this time the big birds had not yet entered the effective range of the anti-aircraft machine gun, he couldn't care about so much, now he had to try his best to buy time for the convoy, as long as the convoy entered the tunnel, it could get temporary safety.

The big bird swooped down in the sky, the one that rushed to the front was a little bigger, and it was very fierce, and the one behind was the one that was scared away by Zhang Xiaoqiang's shot just now, maybe the wound on the head was still painful, this time it was more careful, it carefully hid its body behind the big black bird in front of it, and there was a big posture to send you to death, and I took it.

The big bird in front of it did not taste the bitterness of large caliber, and behaved very fiercely, and at the same time represented recklessness, and when it entered the effective range, 14.5 caliber bullets rained down on it.

After a mournful roar, there was a rain of black feathers in the sky, and countless feathers fell from the sky one after another, no one knew that the anti-aircraft machine gun shot it, and no one knew that it was the bullet of the anti-aircraft machine gun that hit it, and the big bird turned around and rushed to the side at the same time as it was shot, exposing the obscene big bird behind him.......

This obscene big bird had some experience before, it kept shaking its body in the air to avoid bullets, knowing that it rushed to a distance of 300 meters, and when it saw that the bullets in front of it were too dense, it gave up, and flapped its wings and flew to the side after the big bird in front of it.

The big birds flew in front, the dense bullets kept chasing behind them, as they flew higher and higher, the bullets continued to scatter farther and farther away from them, and when the big birds flew out of range, everyone changed the ammunition for the machine guns, Zhang Xiaoqiang pulled out a bullet with half of the bullet left and replaced it with a new bullet chain and looked up at the sky.

Because of the recklessness of the first big black bird, their first attack failed, and the reckless big bird paid a terrible price, and the big bird flew in the sky while chirping at the obscene big bird flying beside him, as if telling his dissatisfaction.

Zhang Xiaoqiang didn't see a wonderful scene in the sky, he turned his head from time to time to look at the long convoy, the convoy had already entered about halfway, and the two big birds on his head were like two thousand pounds of boulders pressing on his heart, and he could only silently pray at the moment that the gods who had never heard of him would bless him to pass this hurdle.

The more anxious he was, the easier it was to make trouble, and a dense burst of gunfire came from the tunnel as he guarded the big bird on his head.

"The third son, the third son heard it, didn't hear it."

Zhang Xiaoqiang shouted loudly at the walkie-talkie, in addition to some chaotic sound waves, there were dense gunshots in the walkie-talkie, and he held the walkie-talkie and waited anxiously for Sanzi's reply.

"Cockroach...... Brother cockroach, there are hundreds of zombies in the cave, and the convoy in front is receiving fire, no problem, it will be solved soon......"

Hearing the third son's reply, Zhang Xiaoqiang felt a little relieved, more than 100 zombies are really nothing, his team members are all killed from the sea of corpses, and there is absolutely no problem in dealing with some zombies that have no possibility of evolution.

Just when Zhang Xiaoqiang was about to snap the walkie-talkie back into his belt, the two big birds flew to both sides in the sky, one left and one right, and when he saw the big birds separated in the sky, he felt a sigh in his heart, bad rookie.

Just as he guessed, the two big birds drew half a circle in the sky and rushed down at the same time, and the situation of the two big birds rushing down at the same time was a two-sided attack, and this time Zhang Xiaoqiang and the two anti-aircraft machine guns had to face attacks from two directions at the same time.

Zhang Xiaoqiang gave an order, the two quadruple outfits were aimed at a big bird, and he was aimed at a big bird alone, and it happened that the big bird he was aiming at was the obscene big bird that had been wounded on the head, and the big bird was constantly passing through the dense bullets, probably because of the reduced firepower, the big bird did not go to the side as before, but rushed directly over.

The big bird's huge and flexible body traveled through the rain of bullets, and in the blink of an eye, it was in front of Zhang Xiaoqiang, this big bird had a deep memory of Zhang Xiaoqiang, seeing Zhang Xiaoqiang was aiming at himself with the thick tube, thinking of the hot pain on his head, the feathers on his body exploded all of a sudden, and his body couldn't help flashing from the front of the Humvee.

The bullet fired in the air chased after the big bird's ass like a festive salute, and the big bird made a cobra maneuver that only a fighter would do before the bullets were about to hit his buttocks, and the wings flapped and followed a back rush, and the body flew flat and became inverted, and after flashing the bullets chasing behind, the body suddenly stopped in the air, and then fell to the ground like a sudden fall, just a line away from the ground, the big bird flapped its wings and rolled up a gust of wind, Countless flying dust rose in the air, covering the big bird's figure.

The dust covered the figure of the obscene big bird, and also blocked Zhang Xiaoqiang's vision, and he couldn't see him firing into the dust, and the corner of his eye took the opportunity to glance in the direction where the other big black bird came from.

Before his eyes were in place, a deep shadow enveloped him, and a huge black figure flashed from the front of the car, followed by a gust of wind that seemed to blow him away.

Zhang Xiaoqiang in the wind could no longer stand in the machine gun nest, half of his body was suspended in the wind, and the only thing that could fix his body was the trigger that was double-buckled, and the trigger was pulled to the bottom by Zhang Xiaoqiang at once, and the remaining ammunition in the magazine was sprayed out of the muzzle.

The wind did not stop, Zhang Xiaoqiang's body and the barrel of the gun hung in a straight line in the air, the machine gun in his hand was constantly spraying bullets, and the strong recoil was all fed back to Zhang Xiaoqiang, who had no place to borrow force, Zhang Xiaoqiang kept shaking on the anti-aircraft machine gun, and the bones on his body seemed to be shaken apart.

Fortunately, the wind came and went quickly, and Zhang Xiaoqiang's body ......fell heavily into the machine gun nest, and before Zhang Xiaoqiang, who felt like he was falling apart, got up from the machine gun nest, there was a loud noise outside, and he hurriedly poked his head out of the machine gun nest and looked at the place where the sound came from.
