After a moment of astonishment and shock, the group continued on their way.

Of course, they called it "traveling," but their speed was still not fast. They had to clear out as many nearby Zombies as possible, and of course, collect Elemental Crystals.

However, due to time constraints, they were now only collecting Intermediate and High Level Elemental Crystals. It had to be said that this was an incredibly extravagant practice. If other Mercenary Corps saw this, there’s no telling how heartbroken they would be.

"Come on, keep practicing your Gun Technique. I’ve already taught you the basic skills. What you need to do now is be fast! Constantly increase your firing and aiming speed, and develop a feel for it as quickly as possible," Lin Xinghai said, instructing Liu Miaomiao while looking at the electronic map on the screen.

The Industrial Park was about 15 kilometers away. It wasn’t a long distance, but it wasn’t short either.

Under normal circumstances, they could have reached it in just over ten minutes. But if they had to fight their way through, it would take at least an hour.

During this time, they would certainly encounter other Mutated Zombies. When that happened, Lin Xinghai would be able to roughly estimate the total number of Mutated Zombies in all of Guanghan City based on their density.

The next leg of the journey was relatively stable, except that the proportion of High Level Zombies had increased again. It had reached a point where for every 10 Mutated Zombies, two would be High Level.

If the Heaven-Sundering Mercenary Corps hadn’t been personally trained by him, with their outstanding collective Gun Technique, they would likely be scrambling to deal with the successive waves of High Level Zombies.

"No wonder Guanghan City is known as a forbidden zone. Even a simple exploration is this difficult. If anyone wanted to gather resources in this city, no matter how many Mercenary Corps came, they would just be sending themselves to their deaths," Lin Xinghai couldn’t help but exclaim.

Fortunately, once he returned and submitted the data, the Military Department would also dispatch an elite team to clear the area. Barring any surprises, capturing an Industrial Park should be achievable.

After all, that Industrial Park was only on the outskirts of this massive city.

RAT-A-TAT-TAT!

BOOM! BOOM! BOOM!

Gunfire and explosions echoed ceaselessly along the way. After advancing for about 5 kilometers, they encountered another Mutated Zombie.

This time it was a Spitter. This type of Mutated Zombie wasn’t particularly strong, but its venom was definitely a troublesome Superpower.

Luckily, there were no other Mutated Zombies nearby to assist it, and it had been spotted early. Just like before, Lin Xinghai piloted his Mecha, using buildings for cover to quickly sneak up on it. Before it could react, he got in close and killed it.

Seeing Lin Xinghai once again return after effortlessly dispatching a Mutated Zombie, the Mercenary Corps’ morale soared, and they fought the Zombies with even more vigor.

When they were only 2 kilometers away from the Industrial Park, the zombie radar once again detected the appearance of a Mutated Zombie.

The observation team quickly identified the new Mutated Zombie with their binoculars. It was an Armored Corpse.

This news made Lin Xinghai frown. It wasn’t that the Armored Corpse was overwhelmingly powerful, but its Defense Power surpassed even that of a Death Claw.

’To think I can sneak up and kill a Zombie this tough and thick-skinned in an instant, like before... that’s obviously not going to be possible.’

Moreover, this Armored Corpse was actively heading toward them, attracted by the commotion. There was no way to avoid it.

Lin Xinghai thought for a moment. This time, he didn’t go out to hunt it alone. Instead, he waited until it was within 1 kilometer of the convoy before taking Fang Tianhe to intercept it.

Fang Tianhe’s Heaven-Splitting Superpower was quite effective against an Armored Corpse.

In the end, with the two of them working together, the Armored Corpse endured more than a dozen attacks before Lin Xinghai finished it off with a single shot.

Of course, the whole process was very short, lasting only about a dozen seconds.

Under normal circumstances, killing a Mutated Zombie in a dozen seconds would absolutely be considered an excellent performance.

But the problem was, this was Guanghan City, a place known as a death trap for Mercenaries.

Although the Armored Corpse only held on for a dozen seconds, that was long enough for it to let out a roar and call for help.

"We’re almost at the Industrial Park. Let’s move quickly, finish our survey, and then retreat immediately," Lin Xinghai said in a low voice.

"Okay!" Fang Tianhe nodded immediately. How could he not understand Lin Xinghai’s concerns?

The only thing they could do now was pray that there were no other Mutated Zombies nearby, or that those Mutated Zombies would ignore the Armored Corpse’s call for help.

Unfortunately, Fang Tianhe’s prayers were not answered. After the convoy advanced another kilometer, the zombie radar detector began blaring its alarm again.

From the direction of the Industrial Park, a full four Mutated Zombies were rushing toward them.

When he saw the four black dots on the zombie radar detector’s screen, the expression on Fang Tianhe’s face instantly turned ugly. As for the others, their reactions were even worse; some were terrified.

Four Mutated Zombies appearing at once was a crisis they had never encountered before.

Even Lin Xinghai’s expression grew a little grave.

"If we had dealt with that Armored Corpse a little faster, maybe we wouldn’t have attracted so much trouble," Fang Tianhe said, blaming himself.

’It’s still because I’m not strong enough. If I had broken through to the Blood Qi Realm, then with the help of Blood Qi Power stacked on top of my Heaven-Splitting Superpower, maybe it really wouldn’t have had a chance to call for help.’

"Don’t overthink it. Those four Mutated Zombies were probably inside the Industrial Park. We would have run into them eventually during our survey; it was just a matter of sooner or later," Lin Xinghai said casually, trying to comfort him.

As for how to deal with these four Mutated Zombies, they would have to wait for the observers to report the specific details before making a decision.

"Report! The four appearing Mutated Zombies are a Hunter, a Spitter, a Giant Arm, and a Blood Worm." The observer used the radar’s positioning to find the four Mutated Zombies, observed them through binoculars, and immediately reported back.

After hearing the names of these four Mutated Zombies, the expressions on the faces of all the Heaven-Sundering Mercenary Corps’ senior members grew even uglier.

They were familiar with the Hunter and the Spitter. If either of these two Mutated Zombies appeared alone, with Lin Xinghai around, they would pose no threat to the Heaven-Sundering Mercenary Corps. But it was a different story when these Mutated Zombies worked together.

A Spitter’s venom wasn’t just for attacking; it could also send other Zombies into a frenzied state. For example, a Hunter, which normally had a Speed of around 2000 points, would experience a massive speed boost after entering a frenzy. Its Speed could even surge to 4000 points, rivaling Lin Xinghai’s.

What’s more, besides the Spitter and the Hunter, the other two—the Giant Arm and the Blood Worm—were the real trouble.

The Giant Arm was a Mutated Zombie whose frontal combat capability was second only to the Death Claw.

Its appearance was somewhat similar to an oversized ape, but its body was not covered in fur. Instead, it was covered by a hard, keratinous layer.

The most outstanding feature of this Mutated Zombie was, of course, its Power. Its two arms possessed a Giant Strength of nearly ten thousand jin.

Moreover, the Giant Arm’s fingers were very flexible, giving it excellent grasping ability. This made it one of the few types of Mutated Zombies that could use "weapons."
