After the armored vehicle was out of danger, it began to slow down, and finally the convoy came to a stop 5 kilometers away from the tornado of hell.

Even here, you can feel the terrifying hurricane, and the basin-sized stones will sweep up and blow in the direction of the hell tornado.

However, this infernal tornado appeared and disappeared just as quickly, and after only 3 minutes, it dissipated at a speed visible to the naked eye.

Countless mud and rocks swept into the sky by it were like hail at this moment, constantly falling down.

Even when the convoy was 5 kilometers away, it was attacked by the same mud and rocks.

Even the armored car was hit by a boulder of hundreds of catties, which made Lin Xinghai feel the horror of nature again.

If it weren't for the protection of armored vehicles, even if he wasn't directly swept into the sky by the hell tornado, when the tornado dissipated, he couldn't bear this kind of indiscriminate range attack.

"All of them, get out of the car and overhaul them." When the sandstone attack was over, Roger ordered.

Lin Xinghai also jumped out of the car, and he found that the people in the other cars also got down, and it was obvious that this was all a unified process.

On the side of the armored car, there is actually nothing to check, this thing is not iron, but made of high-strength alloy, even if ordinary stones are smashed down by hundreds of catties, they will not cause any damage.

Even two multi-purpose off-road vehicles can withstand this attack.

Therefore, there are only two main aspects to check.

The first is the engine, after all, the situation just now is completely overloaded, if you don't overhaul and maintain the engine, there is a high probability that there will be problems later.

The second aspect is rocket thrusters, Lin Xinghai counted them carefully, only to find that the back half of the entire armored car was distributed with a full 16 rocket thrusters.

It's no wonder that in just a few seconds, the speed of the 50-ton iron lump soared to the point that it was about to fly.

In addition to completing basic checks, the most important thing for these rocket thrusters is to refill the energy source.

The energy used by rocket thrusters is not fuel or nitrous oxide in the conventional sense, but an energy crystal.

Just look at the pain on Roger's face, you know this thing...... It's definitely expensive.

"What we're looking for on this mission is this kind of energy crystal?" Lin Xinghai asked.

"It's pretty much the same, but it's a secondarily compressed energy spar, and it's more expensive. The added energy crystals add up to about 3,000 points. Roger said in pain.

Lin Xinghai was also a little shocked when he heard this, according to his understanding, if an ordinary first-level mercenary group goes out to perform a mission, if it deducts various expenses, the number of points that can be saved is only this number.

After half an hour of overhauling, the convoy was back on the road.

In the next part of the journey, there were no more surprises, and soon they entered the suburbs of Tianshan City.

As far as the eye can see, there are not dilapidated houses, but patches of ruins.

The Great Tribulation lasted for 20 years, and all the houses that survived were enough proof of their fortification.

At the same time, the zombie detector on the car is also constantly sounding the alarm.

At first, only one or two zombies appeared inside the detector.

But this number, as the vehicles continued to advance, was rapidly rising, and soon exceeded 10, and then reached 20, 30.

The zombies were simply scattered at first, but as the convoy moved forward, they began to converge.

What surprised Lin Xinghai even more was that almost half of the red dots displayed by the detector were dark red, which represented intermediate-level zombies!

This indicates that the zombies here are definitely an order of magnitude more dangerous than those in the outside world.

Looking at the red dots on the zombie detector, which were still increasing, Lin Xinghai couldn't help but swallow a mouthful of saliva.

Continuing to go deeper, he didn't know what the situation was, but even these zombies that appeared now were not something that their first team could deal with.

Especially those zombies with an intermediate level of danger really have a very strong lethality when they are close behind.

Fortunately, the Sky Splitting Mercenary Regiment did not advance in the same way as before.

Two multi-purpose off-road vehicles that had been playing soy sauce all the time came to the front of the line at this time and drove side by side.

At the firing position on the roof of the car, a mercenary had already sat on it, and the "heavy machine gun" mounted on the roof of the car had been activated.

The statement of activating a heavy machine gun sounds a bit strange, but it is true.

Because of the two heavy machine guns, the barrels began to lengthen, and the entire gun started from the base, rendering a layer of blue light.

I don't know if it's an illusion, Lin Xinghai always felt that there was electricity circulating at the muzzle of the gun.

It can be said that the heavy machine gun after starting is more cool and domineering than before, and it doesn't even feel like a heavy machine gun anymore.

Of course, no one said that these two were heavy machine guns, that was just Lin Xinghai's first intuitive impression after seeing them.

At this time, Roger came to his side and began to tell him about the next tactics, "Use two electromagnetic railguns to form crossfire, as long as the energy and ammunition are sufficient, even if thousands of zombies rush head-on, they can be killed quickly." ”

Lin Xinghai smiled bitterly in his heart, the so-called heavy machine gun was really his wishful thinking.

Of course, Roger didn't know what Lin Xinghai was thinking, so he continued: "The second and third teams will be in the middle, and in addition to dealing with the zombies on both sides, they will also deal with all the emergencies that arise. ”

"Strictly speaking, it's the 'Sky Splitting' and 'Sky Frost' mecha that deal with it."

By the time Roger said this, the two armored vehicles behind had overtaken them and reached the middle of the convoy, and the deck on their roof slowly opened.

Fang Tianhe and Shen Han, the two strongest fighters, had already entered the mecha category and were in a state of standby, ready to attack at any time.

"Then our job is to be in charge of the aftermath?" Lin Xinghai looked at them who had originally taken the lead and came to the rear, feeling really uncomfortable.

Of course, adaptation or not is secondary. What hurts him the most is that if he advances according to such a tactic, he won't stop collecting Yuan Crystals at all!

What about his flesh and blood power? He's going to make a big profit!

"Well, the work after the break is relatively easy, and it can be regarded as a rest for us in disguise."

"Of course, you can't rest, there are so many zombies here as targets, this is an excellent place to practice guns, you must take advantage of it, and strive to improve your marksmanship in the shortest possible time." Roger said.
