Because of their speed, the mutant monkeys rushed into the convoy first, followed by other mutated creatures, and these mutated creatures were also very threatening to humans.

One of them, a pangolin the size of a wild dog, can suddenly emerge from under the car and tear through the tires with its sharp claws, and even the chassis of some cars with weak defenses.

Compared to the convoy, the survivors who walked on foot were the first targets of these mutant creatures, and because they had no car protection, these survivors had almost no resistance in the face of the mutated creatures.

The survivors on the bus could see the survivors walking behind them being chased by a pack of mutant dingoes, who would then plop the survivors to the ground and pull the survivors' entrails out of their butts with their large mouths full of canine teeth.

The entrails of the survivors were pulled out by the wild dogs, dragged to the ground, and pulled out a long trail of blood, screaming while watching their entrails being eaten by mutated wild dogs, the scene was terrifying.

Although mutated wild dogs have been mutated, they have also inherited some of the habits of wild dogs, that is, when attacking prey, they like to take out the internal organs of the prey from the butt to kill the prey.

Because of the habit of wild dogs, when pandas or some animals encounter a siege by wild dogs, if they can't run away immediately, they often sit on the ground to prevent their internal organs from being pulled out.

Mutant pangolins not only like to attack cars, but also frequently attack those who survive, and the claws of the pangolin are so sharp that they suddenly burrow out of the ground, and then tear open the human body in one fell swoop, enter the human body, and easily kill a survivor.

Seeing the tragic experience of the survivors outside, the human beings hiding in the bus had very ugly faces, many people trembled all over, and some timid girls were directly frightened by this scene.

These mutant creatures have very strong attack power, even if the bus with protective measures is equipped with protective measures, it will not last long in the face of the continuous attack of mutated creatures, but because of the existence of survivors walking on foot, these mutant creatures are naturally willing to attack those survivors who are not protected first.

Therefore, as long as there are survivors on foot, mutant creatures generally do not crash with cars equipped with defenses, which is why the self-help convoy will bring a large number of survivors, these survivors are not only free cannon fodder, but can also delay mutant creatures.

Most mutant creatures will attack the hiking survivors first when confronted with a walking survivor and a protected car, but there are exceptions.

Now the exception came up, a herd of mutant bison burst out of the woods, and then there was a rampage, no matter what stood in front of them, the mutant bison would crash straight into it.

The size of this group of mutant bison was much larger than before, and the size of the mutant bison at the head of the group was several times larger than before, the size of an adult elephant, and a green crystal nucleus appeared on its forehead, indicating that this mutant bison had reached the fourth order.

Like an adult elephant, the mutant bison king can easily break through the thick trees of the bucket, and anything in front of it will be smashed, even if a mutant monkey that has reached the third order, because it is too late to dodge, it is directly knocked down by this mutant bison king, and then trampled to death by the mutant bison herd that follows behind.

"Bang!" A violent impact sounded, and the mutant bison king crashed directly into a bus, and the huge impact force not only made the bus seriously deformed, the glass shattered, and even the huge body was directly overturned to the ground.

The wide bus was knocked over by the mutant bison king in one shot, and the other cars and off-road vehicles were like toy cars in front of the mutant bison king, with no defense at all and were easily overturned.

Seeing this group of mutant bison so ferocious, the entire convoy was already frightened and stupid, and for a while, there was a mess, and even the two bulldozers in the front of the road did not dare to continue moving forward because they were afraid of the mutant bison.

"Da da da ,,,," Just when the convoy was in chaos, a burst of intensive shooting suddenly sounded, only to see that at some point, Ye Feng had already come to a heavy truck at the front of the convoy, and was holding Gatling with both hands, constantly shooting at several mutant bison rushing forward.

The Gatling bullet has the penetrating power of a machine gun, even with the rough skin and thick flesh of the mutant bison, it is difficult to resist the bullet, Ye Feng strafed down in one round, and directly killed more than a dozen mutant bison in front of him.

"Keep moving forward and don't stop, or we'll all die." After Ye Feng stopped shooting, he picked up the walkie-talkie next to him and immediately issued an order to the convoy.

Now the convoy is stuck in the mountainous section, if it does not rush out as soon as possible, it will only attract more and more mutated creatures, completely caught in the sea of mutant creatures, and the killing can not be finished, only by rushing out at all costs, there is only the only hope of survival.

The people who can still survive now, there are almost no fools, as soon as they heard Ye Feng's words, they immediately understood that if they don't work hard now, they won't even have a chance to fight hard when the time comes.

The two bulldozers were once again at full power, desperately rushing forward, not only the bulldozers, but even the heavy trucks that followed the bulldozers did not have any scruples, but also bottomed out at the throttle and crashed directly forward.

Whether it was a vehicle blocking the road, or a mutant creature rushing over, the heavy truck directly ran over it, and even a heavy truck directly collided with a third-order mutant bison, and the front of the heavy truck was completely shattered, but the mutant bison was also killed by the heavy truck.

Such a big commotion in front of the convoy quickly attracted the attention of the fourth-order mutant bison king, who roared and rushed towards the bulldozer that was opening the way in front of the convoy.

"Oh no, this mutant bison looks like it's about to storm the bulldozer." Yang Long, who was sitting in the cab of the heavy truck to command, saw the huge bison rushing over at great speed, his face changed, and he shouted in a lost voice.

If the two bulldozers in front of the road are knocked over by this mutant bison king, then the team will lose the construction truck that opened the road, although the heavy truck and excavator can also clear the vehicles blocking the road, but the speed is obviously much slower.

"Damn, I've had enough." Just as the mutant bison king rushed over, a rough voice sounded inside the walkie-talkie.

This voice, Ye Feng is a little familiar, it is Zhang Hu who drives the road roller, this Zhang Hu is a very powerful driver, not only can drive the roller, but also drive the excavator and bulldozer, it is completely a multi-functional driver, can drive almost any engineering vehicle, and the technology is very good.

As Zhang Hu's angry voice sounded, the road roller, which was originally following behind the heavy truck, suddenly turned and crashed head-on towards the mutant bison that rushed over.

Zhang Hu, who drove the road roller, drove the power of the roller to the maximum, crashed through the road guardrail, rushed into the open area on both sides of the road, and activated the vibration function.
