Boom, boom, boom...

Gas tank shells fell to the ground, balls of flames soared into the sky, buildings collapsed, and corpses and fragments soared into the sky.

The first wave of more than 30 gas tank shells covered the mutant's main force suffered heavy damage.

But this was just the beginning, and the second wave of shelling attacks again, and this shelling extends backward, covering the subsequent forces of the main force of the mutant, causing even greater damage.

At the bridgehead position, Wu Xin stood on the roof and looked at the city area covered by artillery fire in the distance, and felt relieved.

The situation that was originally full of crisis has finally been reversed.

Looking back on the previous battle, even though they were fully prepared, they almost made the mutant turn around.

You should know that the survivors in the previous life did not have the current conditions, but they only felt more and more difficult to face the mutant after two or three years.

But in this life, the end of the world has arrived for less than a year, and the mutant has become so difficult, which is indeed beyond his expectations.

"Perhaps, the mutants in the previous life did not show all their strength at all..." This is the only explanation that can match the current phenomenon.

The reason why the mutants in the previous life felt weaker than they are now may be because the survivors at that time were also weaker and could not threaten the survival of the mutants at all. Therefore, they did not have any evolution targeting survivors, but normal evolution and development will survive.

The man was forced into a desperate situation.

In this life, because of his rebirth, the survivors, especially those in Lingchuan, have greatly strengthened their strength, and have even been so strong that they threaten the survival of the mutant.

Under such fierce confrontation and competition, the evolutionary potential of the mutant was completely stimulated. In order to survive with humans, various new evolutionary routes were produced in a targeted manner, and many of them had not seen in his previous life.

Variants of past.

"What a terrible creature..." Wu Xin couldn't help but sigh.

Such powerful adaptability and adaptability made Wu Xin a little doubt whether non-mutated creatures represented by humans can no longer keep up with the situation?

However, looking at the violent explosions in the distance, Wu Xin's heart became firm again: "Humans have not lost yet..."

Just as Wu Xin was ecstatic, the walkie-talkie in her hand rang, "Report, there are mutant activities on the outside of the position!"

Wu Xin then came back to her senses and asked at the intercom, "Where is the location!?"

“South and southwest direction…”

Wu Xin immediately came to the corresponding position on the roof and looked at those places with a night vision instrument.

I saw that there were mutant bodies scattered in and out of nearby buildings in some corners more than 100 meters south and southwest directions.

"Is the target still here?" Wu Xin put down the night vision device, then called the artillery team in the position, and fired a shot to the place where the mutant appeared and tried.

boom!!

A building with mutants was blown up.

However, Wu Xin originally guessed that the mutant nest explosion phenomenon did not appear. On the contrary, it was surprisingly quiet.

"What's going on?" Wu Xin was a little surprised and asked the artillery team to shoot a few more shots, but the situation was still the same.

At this moment, a gas tank shell landed on the open space in front of a building with mutants. After a violent explosion, the smoke dissipated and a large pit was blown out of the ground. Wu Xin accidentally swept it.

But his face suddenly changed.

I saw a straight collapse along the ground more than ten meters in front and behind the big pit. At first glance, a tunnel was blown up, and the direction of the tunnel was extending was the bridgehead position.

"Everyone is alert, the mutant is digging the tunnel!!" Wu Xin picked up the intercom and shouted.

But his warning was still one step late, and an abnormality had appeared on the ground of the bridgehead position.

Some of the grounds that were originally covered with concrete suddenly shattered and collapsed, revealing a hole of about one meter, and then a new variant that had never been seen before emerged from it.

This variant has a pair of claws that are conducive to digging, but unlike the claws used by Night Ghost to attack, the claws of this variant are very thick and short, and have evolved specifically for digging soil.

As this variant drilled out of the ground hole, night ghosts followed and came out of the ground hole.

The sudden mutation that emerged from the underground caught the people at the bridgehead position off guard, but fortunately, the bunker group of the positions had entered a state of combat readiness in advance due to the previous unfavorable situation.

These bunkers were prepared to be broken through at the beginning of their design and construction, so they had shooting holes opening into the position. After discovering that the mutants appeared inside the position, these bunker groups attacked.

However, the holes dug by the mutant were everywhere, and many holes were blocked by building living obstacles, which still allowed the mutant to pour into the position in large quantities.

"All units stick to waiting for assistance, and each unit sticks to waiting for assistance... the base gate and immediately enter a defensive state..."

Wu Xin did not panic like this, but immediately issued an order and notified the base gate to be prepared for defense in case the mutant breaks into the base.

After everything was arranged, Wu Xin notified the command boat.

"The mutation attacked the bridgehead position through the tunnel!?" Liu Zheng was extremely shocked.

Although Liu Zheng had felt that the target of the mutant must be the bridgehead position before, he did not expect that the mutant could be prepared so thoroughly.

The mutant attacked the bridgehead position during the day, and seemed to be forced to "surround Wei and save Zhao", but now it seems that the mutant passed the battle just to arrange the tunnel troops near the position, in order to indeed be this raid at night.

The series of battles that took place tonight, such as harassing artillery positions and attacking the No. 4 defense point, may be just to attract their attention and mobilize the base's troops.

But it doesn't help to figure out all this now. He only cares about one question, "Can the position be held?"

"The person is in the position!" Wu Xin replied firmly.

After saying this, he heard a mutant roar and gunshot from the intercom and broke off the contact. Liu Zheng was extremely anxious and immediately said to the contact official: "Order the defense point No. 1 to return to the rescue immediately...

…”

At the bridgehead position, on the roof of Wu Xin, a night ghost was lying a few meters away from his feet, and several soldiers protected Wu Xin behind him.

While Wu Xin was talking to Liu Zheng, a night ghost suddenly climbed up to attack him, but was killed by the guards beside him.

A guard said to Wu Xin anxiously: "Commander-in-chief, I will call the helicopter immediately..."

"No, I am the position commander now, I must stay!" Wu Xin rejected the guard's suggestion to let him evacuate, but instead picked up a 56-rushing from the weapon storage point on the side.

With a click, Wu Xin put a gun in his mouth and said to several guards: "Prepare for battle!"
