The armed convoy forcibly broke through the encirclement network formed by the plague beast tide that was ambushed at the exit of the canyon, and used the furious fire network to shoot the enemies attacking the convoy without landing on the ground, and then truly entered the endless wasteland.

The second wave of plague beasts in the wasteland had not yet hit, and the convoy took advantage of this rare time to line up in a "hexagonal" formation according to the original plan. Each armed heavy field vehicle is located at a point in the hexagon, with a 20-meter gap between adjacent armed vehicles.

The muzzles of the 20 anti-aircraft machine guns and the muzzles of the 6 heavy guns are facing the perimeter of the hexagonal formation, and the machine gunners and heavy gunners who control them sit in the combat rooms isolated from the carriages, and there are sentries as "signal detection towers" who are responsible for helping them to guard against the outside world, beware of the plague species in the sky and the wasteland, and tell the machine gunners and heavy gunners the enemy's location as soon as there is an enemy attack.

"Direction at 10 o'clock on the ground, 600 meters away."

"At 2 o'clock on the ground, at a distance of 950 meters."

"The sky is at 4 o'clock, 1100 meters away."

"Ground ......"

Sentinels observe the enemy's position through telescopes that automatically measure their values, and report accurate information to the machine gunners and heavy gunners on public channels. Each armed vehicle has its own angle and range of responsibility, and when accurate information is transmitted to the machine gunners and heavy gunners in the corresponding area, they will determine whether to fire remotely based on the distance of the enemy.

A few seconds later, the second wave of plague beasts struck the ground from the 2 o'clock direction of the convoy for the first time, and the momentum was like a fierce wind of yellow sand rolling up in the wasteland, surging towards the convoy.

The direction of 2 o'clock was the attack range of the No. 2 armed car where Wu Qi and his party were. Four anti-aircraft machine guns swung in a volley, and a raging and relentless metal storm slammed into the oncoming tide of plague beasts at high speed.

Countless slender and huge golden light projectiles hit the bodies of the plague species at the end of their high-speed flight, instantly striking spiral depression wounds on their bodies, and the wounds spurted out fountain of blood; Some of the bullets grazed the body of the plague species, and after emitting a wind-breaking scream, they slammed downward and violently on the earthy yellow wasteland land, setting off loess pillars that briefly left the ground.

The plague species that arrived from the far end of the horizon sensed the breath of the bones, not one after another, but from all directions, heaven and earth!

By the end of the first round of shooting, the wasteland at 2 o'clock had become a bloody corpse field. Behind the bone field, there was also a wave of plague beasts rushing across the corpses of the same kind towards the armed convoy heading for the west of the wasteland, and the waves of plague beasts in the other five directions were no exception, one after another breaking into the range of the most powerful anti-aircraft machine guns and heavy artillery.

The firing range of anti-aircraft machine guns is actually calculated in kilometers, and when the muzzle of the gun is only a few hundred meters away from the enemy, the armed convoy is certainly dangerous, but the hit rate of the rifled bullet will be increased by 2 to 6 percent. This is also a plan that has been determined at the beginning of the implementation of the return plan, in order to save the cost of ammunition.

In the scorching sun, a flock of black-pressed plague birds gathered high in the sky and swooped down on the armed convoy below! Several heavy cannons let out a roar, and one after another explosions of smoke filled the air like fireworks of destruction.

Dense fragments of corpses rained down, mingling with pools of corpses on the ground, and were crushed by the wheels of the armed convoy.

In 40 seconds, the armed convoy forcefully shredded the plague beast tide from all directions, sky and ground without being bullied by any plague species within 50 meters, and survived the second wave of plague beast tide unscathed.

After the armed convoy drove away, countless black shadows sprung up in the far reaches of the horizon in the vision of the sentinels' telescopes, and countless small black dots appeared in the distance of the sky and gradually grew larger.

Mine 130 is 50 kilometers away from the "gate" closest to the Dawn base, and at the speed of the armed convoy, if it is invincible, it will take up to 20 minutes to return to the mine safely. It's just that 20 minutes is too idealistic a number, and it requires perfect luck without encountering any third-order overlords along the way.

Time passes by second, and battles and victories always happen in an instant. All those who rode in armed heavy field vehicles felt that the estimated 20 minutes were longer than at any other time.

In the No. 2 armed car, Wu Qi and other soldiers of the escort team sat quietly in their seats, and the air was silent as if they were dead.

So far, the armed convoy that has been heading towards the Dawn base has not encountered a situation where the soldiers of their mine escort team need to leave the wagons to fill the gap in combat effectiveness. The commander of the car No. 1, the sentries of each armed car, the machine gunners and the heavy gunners had to tense their nerves, and they didn't.

But they could also see through the front window the tide of plague beasts that were coming towards them like a sandstorm, the rain of bullets and bullets that were galloping, and the scene of countless plague beasts with hideous shapes being crushed and falling.

Such a picture is no different from war, and no one can relax their nerves when they look at it all the time, let alone the roar of anti-aircraft machine guns and heavy artillery.

Wu Qi's nerves have been tense and unable to relax, as are Gao Yuan, Guo Baibai, Kress, Morley and others. Everyone had a worried face, and the atmosphere became imperceptibly silent.

"It's been a few minutes......"

A soldier muttered to himself, then looked up at a cuboid electronic clock hanging from the wall of the carriage. From the beginning of the return trip, the beating moment on the electronic clock with red letters on a black background becomes a timer starting from zero. The numbers and symbols on the timer represent "2 minutes and 57 seconds".

"How can time pass so slowly?" He grumbled, his head bowed and his head in his hands.

"Don't worry so much, hasn't the armed convoy been moving smoothly all the time? Whoever can stop us with so many plague species, we will definitely be able to return to the base safely. Besides, everyone's lives are in the same boat, so what is there to be afraid of. The soldier next to him patted the frustrated soldier on the shoulder and comforted.

The frustrated soldier raised his head, his eyes did not change much: "I really envy you for being so comfortable." ”

No one spoke in the carriage, there was no other sound except for the sound of gunfire coming from outside, and the communication between the two soldiers was very small, and it still reached the ears of Ye Zheng, who was sitting in the front seat.

"Instead of worrying meaninglessly, you should close your eyes and recharge!" Ye Zheng said coldly.

The two soldiers quickly shut up.

The timer beat slowly, and the time finally came to five minutes. All things are right, the armed convoy has already crossed a quarter of the way back.

At this moment, the view from the front window changed slightly. A large group of extremely dense plague beasts suddenly appeared in front of him, a large area of black oppression, like a "dark cloud" walking on the ground!

And between these "dark clouds", there is a huge black shadow that stands out from the crowd! The black shadow was tall and majestic, square and domineering, like a thousand plague species!
