I'm invincible since the end of the world

Seeing that Roger and Xu Hao seemed to be working together to deal with the advanced zombies, Lin Xinghai was immediately refreshed and observed carefully.

This kind of advanced zombie gave him a lot of pressure. Seeing how others dealt with it, he could also use it as a reference when he faced it in the future.

After Roger loaded the special bullet, he took out a high-power scope from the pocket of his combat uniform and installed it on the Ripper rifle.

Only after doing all this did he start to aim the gun, but compared with the previous ease, Roger was now absolutely focused.

"Are you going to use all your strength?" Lin Xinghai was looking forward to it.

On the other side, although Xu Hao did not load that kind of special bullet, he also took out a high-power scope and installed it on the Ripper rifle.

Then, aim!

Compared with usual times, this time the aiming time was quite long, lasting for 5 seconds.

Of course, this was also to wait for the advanced zombie to get closer.

It was not until the other party approached 30 meters from the convoy that Xu Hao pulled the trigger.

Bang!

A clear gunshot sounded, and Lin Xinghai could see that the high-level zombie, who was running at high speed, obviously dodged at this moment.

He knew very well that if he had fired this shot, the other party would definitely have dodged it.

But Xu Hao's shooting skill was definitely 60% proficient, and the prediction was just right, and the bullet hit the chest of the high-level zombie.

Even ordinary bullets of the Ripper rifle have terrifying attack power. If an ordinary zombie is shot, the bullet will definitely pass through the body.

Even if it is a mid-level zombie, it will stagger back a few steps if it is hit in the chest.

But the high-level zombie in front of him actually paused for a moment, and there was not even much blood flowing out of his chest. The bullet should have been stuck in the sternum, and the internal organs were not injured.

Such injuries, on a zombie, are not much different from skin injuries. After a slight pause, the high-level zombie immediately adjusted its body shape and wanted to continue rushing forward.

However, this slight pause was a flaw after all.

Such a flaw is fatal in Roger's eyes.

Bang!

The gunshot sounded, and the special bullet flew out of the gun barrel, without giving the advanced zombie any time to dodge, and hit its forehead, and then flew out from the back of the head.

Plop!

This aggressive advanced zombie died just like that, without even a wave.

Everything seemed so easy and simple, Roger and Xu Hao only fired one shot each.

But Lin Xinghai knew very well that this was entirely based on the excellent shooting skills of the two.

Especially Roger, who was able to capture that fleeting opportunity, his shooting proficiency must have reached 70%.

Of course, this also proved the horror of advanced zombies from the side.

According to Lin Xinghai's estimation, if you want to rely on your personal ability to kill it, then the proficiency of shooting must reach more than 90%.

"It's getting more and more dangerous to go deep into the city! Should I improve my shooting proficiency?" Lin Xinghai fell into deep thought.

Even if he becomes a gene optimizer, he will definitely not be able to defeat this kind of high-level zombie. He can only win by relying on guns.

But in the current situation, he has no chance to collect blood energy.

If he improves his gun skills and does not encounter enough zombies when he returns to the shelter, his plan to become a gene optimizer will be ruined!

Although his strength will increase more if his gun skills are improved, he cannot hold a gun in the shelter.

He always feels uneasy because his own strength has not been improved.

Especially the revenge from the Axe Gang, he has to guard against it.

"Alas, I can only take it one step at a time. I am still relatively safe now. I will talk about it when I really encounter danger." Lin Xinghai shook his head and stopped thinking about it. Instead, he concentrated on killing zombies.

The attack of high-level zombies seemed to be just a small episode for everyone.

During this process, those old mercenaries did not even look at the high-level zombie.

It is obvious that this is not the first time that everyone has encountered such a thing. They also have sufficient confidence in the cooperation of Roger and Xu Hao.

And in fact, this is indeed the case. As the convoy goes deeper, there are more and more intermediate zombies, and even advanced zombies appear from time to time.

Of course, these advanced zombies may not appear behind the convoy, sometimes in front, sometimes on the side.

But no matter which direction they attack the convoy, the routines they encounter are the same.

Someone attacks first, causing it to pause and reveal a flaw, and then someone with better shooting skills will directly use special bullets to attack the head and kill it with one shot.

Time is passing quickly, and soon 20 minutes have passed, and the convoy has advanced 7 kilometers.

In this process, Lin Xinghai also discovered that the direction of the convoy's advance had been planned long ago.

In fact, if there is no such plan, it is impossible to advance.

Because there are collapsed houses everywhere in the city, the original roads are either buried or broken.

If you want to go deep into the city, you need to clear a section of the road yourself.

The cleaning work was obviously done by the Lietian Mercenary Group when they entered Tianshan City last time, so this time the in-depth exploration was so smooth.

But there are always accidents, and this is what happened at this time.

They are now driving on a dilapidated road with many potholes on the ground, as well as some abandoned cars and rocks blocking the way.

But these cannot affect the convoy's progress.

However, when a 10-story building collapses directly and lies across the road ahead, there is no way to move forward.

This high-rise building obviously collapsed in the past few days, so there is no way to clean it up in advance.

Lin Xinghai was a little curious. What should he do in case of such an emergency?

Soon he got the answer. "Split Sky" and "Sky Frost", which had been on standby, finally went out at this moment.

Driven by the pneumatic device, the two mechas jumped lightly and jumped off the armored vehicle, heading straight for the collapsed house.

In this process, of course, they will encounter many zombie attacks.

However, these zombies are useless in front of the mechas made of special alloys.

The 5-meter-high mechas are like kicking a ball to deal with these zombies. A large number of them will be kicked away with one kick.

Rushing to the collapsed high-rise building, Fang Tianhe controlled the "Sky Splitter" and pulled out the giant vibration blade behind him.

Swish, swish, swish, swish!

At this moment, the mecha showed a flexibility that was inconsistent with its body shape. As the mechanical arm swung quickly, dozens of huge blades appeared, and in a flash, the high-rise building blocking the way was chopped into pieces.

Then, the two racks turned into... porters.

They lifted the building that was cut into pieces and threw it aside.
