After Han Feng saw Su Ningxue's vague report, his brows furrowed slightly, but he didn't express any opinions, but walked directly out of the RV and said to Su Ningxue:

"I'll follow you to see it."

In the northeast corner of the county seat of Jinxian County, a group of soldiers holding Type 95 rifles were forming a group to prevent soldiers from other Apocalypse organizations from approaching.

On the ground behind them, there was a round hole with a diameter of 7 or 8 meters, and this round hole was what Su Ningxue said was abnormal.

"This is it, our soldiers of the Second Legion, who discovered this thing while solving personal problems. If there was only this trace at the scene, this thing might have been ignored, but three hundred meters in front of this trace, there was an identical trace, which made me feel a little puzzled. ”

Han Feng looked at Su Ningxue and pointed out the huge round hole, and couldn't help but take a step forward, then casually picked up a stone on the ground and threw it towards the round hole that seemed to lead to the depths of the earth.

One second...... Two seconds...... Three-second ......

Han Feng's face changed slightly after seeing that the stones he threw down had completely disappeared like mud cows into the sea, and then he turned his head and asked Su Ningxue:

"Is the other one you found the same as here?"

"That trace, exactly the same as the mark here." Su Ningxue nodded solemnly and responded.

"Let all the regular troops immediately withdraw from the county seat of Jinxian County, and at the same time notify the silver-level evolutionaries to assemble." Han Feng had already roughly judged that there was a problem at this moment, the bottomless huge round hole in front of him obviously couldn't have been made by humans, so what could create this round hole could only be one thing - a mutant beast!

At the same time, according to the diameter of this round hole, the size of the mutant beast is calculated, then the mutant beast that created the round hole will definitely not be lower than the silver level, and even this mutant beast may be at the gold level.

However, why there are mutant beasts of this level in Jin County, this makes Han Feng a little puzzled, according to reason, gold-level mutant beasts are almost impossible to appear in places with frequent human activities.

The flow of people in Jin County before the outbreak of the apocalyptic virus was not small, and at the same time, there were no national protected areas around Jin County, according to theory, it was absolutely impossible for Jin County to have mutant beasts above the silver level.

With Han Feng's order, the chariots of the First Army and the Second Corps, which had just entered the county seat of Jin County, all restarted their engines, and with the roar of the engines and the black flames spewed out from the tail of the chariots, all the troops who had entered Jin County quickly withdrew from Jin County.

When all the regular troops withdrew from Jin County, four silver-level evolutionaries stood behind Su Ningxue, and Li Chao, the commander of the First Legion, also came to Su Ningxue's side.

At this time, Han Feng, who had been standing in front of the bottomless round hole, flashed a cold light in his eyes.

He directly exuded the full aura of a gold-level evolutionary.

When Han Feng burst out with all the momentum of a gold-level evolutionary, Li Chao and Su Ningxue, who were standing behind Han Feng, and the other four silver-level evolutionaries, couldn't help but take a step back.

A silver-level evolutionary standing behind Su Ningxue muttered to himself as he retreated: "Sure enough, a gold-level evolutionary!" It's so strong! ”

Just after Han Feng burst out with the momentum of his whole body, Jin County, which originally seemed to be normal, suddenly shook.

"What's going on?"

The expressions on those silver-level evolutionaries who remained in Jin County completely changed after they saw that the ground began to tremble slightly, and the small pebbles on the ground also began to beat regularly.

Even Li Chao and Su Ningxue, the two silver-level peak evolutionaries, had solemn expressions on their faces.

The ground shook slightly, giving them a bad premonition.

And after Han Feng felt the vibration coming from the ground, he also had a general understanding of the level of the mutant beasts lurking underground.

The mutant beast lurking underground is definitely a gold-level mutant beast.

If it was a silver-level mutant beast hiding underground at the moment, then this mutant beast would 100% choose to continue to hibernate after feeling the momentum of Han Feng, and would not dare to show its head at all.

Only gold-level mutant beasts would have the courage to appear in front of Han Feng.

When Han Feng felt the vibration coming from under his feet getting stronger and stronger, he immediately turned his head and shouted at Su Ningxue behind him and the silver-level evolutionary led by Li Chao:

"We're all going backwards, and I don't think this mutant beast is going to be small."

"Understood!"

All the silver-level evolutionaries who had been reminded by Han Feng did not dare to slack off at all, and quickly retreated.

Even Han Feng himself took a few steps back, waiting for the appearance of the suspected gold-level mutant beast.

"Hiss——!"

With Han Feng and all the silver-level evolutionaries of the First Legion and the Second Legion, they retreated.

Directly below where Han Feng was standing, an extremely ugly roar suddenly sounded.

This roar is almost like the noise produced when you rub your fingernails against a blackboard, and it is unusually ugly.

And the people who heard this roar couldn't help but cover their ears, when this noise reached the ears, it would actually make people feel nauseous and want to vomit, and there would be bursts of dizziness from the depths of their minds.

Even in the county seat of Jinxian County, some buildings with relatively intact glass have a whole piece of cracks, and they burst instantly!

"Is it a sonic attack?"

Han Feng, who covered his ears and flew back again, flashed a melancholy in his eyes.

Sonic attacks and spatial attacks, which are disembodied attacks, are often the most difficult to deal with.

They attack by coming and going without a trace, and are often unguardable.

Moreover, such attacks are often group attacks, which can cause a large number of casualties.

"Let all the regular troops of the First and Second Legions retreat another 10 kilometers, and even you will all leave the battlefield!"

After Han Feng judged that the mutant beast that slowly emerged from the ground, its attack method was most likely a sonic attack, and immediately asked Su Ningxue and Li Chao to leave here with several other silver-level evolutionaries.

Originally, he still thought that Su Ningxue and Li Chao, under his protection, would be able to face the gold-level mutant beasts in person, so that their bodies could have the opportunity to break through the silver.

But when he found out that this mutant beast actually used a sonic attack, Han Feng decisively dispelled this idea.

In the face of mutant beasts that use sonic attacks, if one is not good, it will cause casualties.

He didn't want Su Ningxue and Li Chao to die here in vain.
