Zombies only have the instinct to prey, and when they get out of control, their first reaction is to attack the convoy that rushes into the corpses.

At this time, in order to rush into the corpses, the soldiers used up all the remaining bullets.

Fortunately, the FK Titans and armored vehicles have also joined the convoy at this time.

There were two behemoths driving the way ahead, and the convoy followed closely behind, although they kept colliding with the corpses that rushed up, and the vehicles were bumpy and swaying, and there was a risk of being overturned by the corpses at any time, but they still rushed out of the corpses dangerously.

At this moment, there are less than 10,000 corpses left in the original 100,000 corpse tide, and without the command of intelligent zombies, there is almost no threat.

Shen Bai, who rushed out of the corpse group, no longer wanted to pay attention to these zombies.

"Everyone, return to base."

With the death of intelligent zombies, this zombie crisis has been resolved.

In fact, this crisis is really dangerous, especially when a large number of T2 zombies rush to the wall, if it is not for the use of laser cannons, the front line of defense may collapse.

Similarly, in the face of more than a dozen T3 zombies, without the appearance of the FK Titan, the result will also be very dangerous.

But in any case, after this crisis is passed safely, there should be no situation that can threaten Shen Bai's base for a long time to come, and there will be enough time to recuperate.

Shen Bai got down from the skylight and sat back in his seat.

At this moment, in his consciousness, the voice of the system suddenly sounded.

"Detected that the host killed the G-type zombie, open the system upgrade module. Upgrade requirements, kill 10 G-type zombies, the current progress is 1/10. ”

The sudden sound of the system made Shen Bai stunned for a while.

Type G zombies? This is supposed to refer to intelligent zombies, right?

But killing 10 intelligent zombies can start the system upgrade?

It has been so long to get the system, but the system rarely releases tasks, and this mission made Shen Bai stunned for a while, and he didn't know how to express his inner feelings for a while.

Although he was a little confused, Shen Bai was more looking forward to it, now the system is so powerful, what if it is upgraded? Wouldn't that be against the sky?

At present, with Shen Bai's combat power, it is completely crushing against ordinary corpses and survivors, but in the face of those uncontrollable mutated zombies or survivors with large firepower, there is no chance of winning.

……

Ten minutes later, the convoy returned to the base.

At this time, it was already past two o'clock in the morning, but the base was still brightly lit.

A large number of survivors assist in the disposal of zombie corpses outside the base.

Since all the gasoline had been used up while guarding the base, the only way to burn the corpses was to light them with firewood such as tree branches.

There is no shortage of forklifts and other equipment in the mining area, which saves a lot of effort, otherwise it would be impossible to gather the corpses of tens of thousands of zombies together with only a hundred ordinary survivors.

The corpses were piled up into small knolls and then placed on firewood.

As the piles of corpses were ignited, in the darkness of the night, they turned into clusters of torches, flickering with flickering fire.

This is much slower than the previous use of gasoline to support combustion, so the efficiency of incineration of corpses is much slower, and it may not be able to burn all of them, but this is also a compromise that has no choice.

The corpses of zombies are impossible to leave unattended, and they are piled up outside the base, and the rotting corpses will cause a lot of unnecessary trouble.

……

After returning to the base, Shen Bai was not in a hurry to rest, and after the battle, there were still many things that had not been dealt with.

The first is the loss of the statistical base.

Although the zombies failed to break into the base in the end, the loss of the base in this battle was not small at all.

In addition to a large number of casualties among soldiers, the material consumption of the base was also considerable.

In order to stop the zombies with that fire, all the gasoline reserves in the base are exhausted, and the next thing is to find a gasoline replenishment immediately, otherwise most of the gasoline-powered vehicles in the base will soon become scrap metal.

In addition, the guns stored in the base storeroom are still there, but all the ammunition is gone, in other words, except for the guns that can automatically refresh the soldiers, the other guns in the base have also become burning sticks.

It is worth mentioning that among the gifts that received regular army units in Wuyun City, in addition to a few boxes of ammunition, there was also a box of grenades.

When the zombies were besieging the city, Shen Bai never used this box of grenades, the lethality of the fragmentation grenades to the zombies was limited, and a box of grenades themselves was not very much, even if they were used, it was difficult to cause any substantial effect.

So Shen Bai left it at the end, preparing that in case the base really couldn't be defended, he would use a grenade to blow up a bloody road, and cooperate with armored vehicles and FK Titans to break through the base.

Unexpectedly, in the end, the grenade was not put to use.

Finally, there's the vehicle.

During the zombie siege, the vehicles did not do much, except for the FK Titans, armored vehicles and a few modified combat vehicles that rushed out of the base to wreak havoc among the corpses, the other vehicles were parked in the base.

But then, the corpses began to evacuate, and Shen Bai and the soldiers pursued by car, in order to find the traces of the G-type zombies in the corpses, they did not hesitate to rush directly into the corpses.

Although zombies are flesh and blood, most vehicles are not designed to hit people, in order to ensure sufficient speed, many positions are not even made of steel, and it is naturally impossible to be safe and sound under violent impacts.

More than half of the more than 40 off-road vehicles pursued out had to undergo major repairs and maintenance, and although the mercenaries were good enough to repair the vehicles, it was unclear whether the spare parts in the base were enough to repair all the vehicles.

Not only ordinary vehicles, but even the FK Titan also needs to be repaired, in the previous battle on the wall, the FK Titan collided head-on with the T3 zombie, although the T3 zombie was knocked out, but the frontal armor was also deformed.

If you want to say that the most seriously damaged vehicles, it is undoubtedly the modified vehicles of Hong Fatzi.

When the FK Titan and the armored car rushed out of the base, these cars followed closely behind, relying on inlaid steel plates, windows, tire guards, and modified high-power diesel engines, and they also crashed into the corpses.

But these modified combat vehicles, after all, are not military armored vehicles, they hit back and forth in the corpse group, seriously damaged, the body is seriously deformed, and the engines of several vehicles are also directly scrapped due to long-term high-power operation, and they did not even follow the large army to chase and kill the corpses.

The mercenaries have already overhauled the modified vehicle and have come to the conclusion that it cannot be repaired.

As civilian modified vehicles, it is already commendable that these modified combat vehicles can have such brilliant records.

Shen Bai felt a little pity, but he wasn't particularly nostalgic.

These modified vehicles, after all, are only modified by civilian vehicles, even if Hong Fatzi's craftsmanship is good, its upper limit is limited to this.

This made Shen Bai feel very distressed, after all, he didn't know when he would be able to draw the combat vehicle.
