High-level martial arts: Contract cashback, invincible starting from the Zerg.

After the meeting, the Guard Headquarters dispatched four more teams of guards to the main gate of the underground city located in the suburbs.

The Super Beast Dungeon has always had only one entrance. The other entrances were simply multiple passages opened by the government for easier inspection after the Super Beast left the Great Xia Kingdom.

However, these passages were actually useless, because no military or police officer dared to enter that forgotten underground city.

Only with Ye Qingnan and Chen Feng, two Earth-rank experts, and Master Wu Kong joining the exploration of the dungeon, was everyone's safety almost guaranteed.

......

When five guard assault vehicles arrived at one of the entrances to the behemoth dungeon.

As soon as Chen Feng got off the bus, he looked at the huge tunnel entrance.

It was a dark, enormous tunnel. The entrance was spacious yet oppressive, with rough, uneven stone walls on both sides, covered with ravines of varying depths and jagged edges.

The stone wall was covered with a thick layer of moss and unknown fungi, which shimmered with an eerie green light in the dim, almost imperceptible light, as if ghosts from another world were spying on it.

In front of the entrance to the passage, there were many messy ruins and debris.

"Why did we come here instead of going straight in from the same place we came from last time?" one of the guards asked, puzzled.

"Although there will be more automated weapons and golems if we enter through the main gate, we have the access code, which will allow us to enter the dungeon's control room more quickly," said Ye Qingnan. "In addition, the terrain here is more open, with enough cover to prevent the golems from self-destructing."

At this moment, Chen Feng was carrying a heavy box off the armored vehicle.

The box was a weapon case weighing nearly half a ton, but in Chen Feng's hands, it was moved around as casually as a toolbox.

"Chen Feng and I will each carry a heavy weapon case containing a rocket launcher capable of remotely locking onto targets and a 600mm diameter electromagnetic pulse grenade, which can interfere with or damage the electronic systems of automatic weapons, causing them to become chaotic or out of control, or even paralyze the entire power grid."

As Ye Qingnan spoke, she took another heavy weapon case from Master Wu Kong's hands.

Master Wu Kong then picked up a "Azure Thunder Formation-Breaking Halberd".

The halberd body is made of a high-strength titanium alloy frame and covered with nano-ceramic composite armor. The halberd head can extend two energy blades, which are activated by a plasma generator and can easily cut through the composite armor of modern armored vehicles.

The front magazine of the war halberd contains 20 miniature electromagnetic armor-piercing rounds. The warheads are made of a composite material of tungsten alloy and depleted uranium, with an initial velocity of 2000 meters per second, capable of penetrating 500 millimeters of homogeneous steel plate.

That was the elite weapon used by the first captain of the Starfish City Guard, but the fighting method was extremely compatible with Master Wukong's fighting style.

Master Wu Kong: "Being able to personally use the 'Azure Thunder Formation-Breaking Halberd' even once makes my trip worthwhile."

Ye Qingnan: "The best is yet to come. Let's go, you two."

Chen Feng: "Okay."

However, just as Chen Feng was about to follow Ye Qingnan into the dark passage...

Liu Siyu called out to Chen Feng.

Chen Feng turned around and saw Liu Siyu walking quickly towards him.

Chen Feng looked at Liu Siyu in front of him and seemed to find that, perhaps because of her long ponytail, her overall image was not as sharp as before, and her clothing seemed to have become a little softer.

"What's wrong, Sister Siyu?"

"Chen Feng...no, Vice Captain..." Liu Siyu looked at Chen Feng with some hesitation, but there seemed to be a hint of evasion in her eyes.

"Just call me Chen Feng, Sister Si Yu, after all, you are my senior," Chen Feng said with a smile.

"Chen Feng...actually, ever since you shielded me from the aftershocks of the explosion, I've wanted to tell you this..."

"What did you say...?"

"explain......"

Chen Feng looked at Liu Siyu, who was stammering, with some doubt, but he seemed to vaguely sense Liu Siyu's unusual behavior towards him.

Her eyes lacked some of the coldness and sharpness expected of a berserker, but gained more gentleness and shyness.

Her originally upright posture became slightly stiff, and her hands unconsciously hung down at her sides, making her look like a little girl who had done something wrong.

Seeing Liu Siyu's face flush slightly as she struggled to speak, and her lips moving slightly as she stared blankly at Chen Feng, as if she didn't know what to say.

"Sister Siyu, you can say whatever you want," Chen Feng said with a smile.

"Chen Feng, well... I'm really grateful to you that time." Liu Siyu finally sighed and said with a hint of disappointment in her eyes.

Chen Feng looked at Liu Siyu, who seemed hesitant to speak, and couldn't help but smile warmly.

"It's alright. I know Sister Siyu took good care of me in the past, so it's only right that I repay her."

"kindness!"

......

As Chen Feng stepped into the dark tunnel, his keen senses immediately detected a chill.

The passage seemed to be filled with a thin layer of mist, as ethereal as a veil, yet carrying a heavy, weighty texture, as if the corpses of countless creatures had once rotted and fermented here, and the nauseating lingering stench still hung in the air.

As the group ventured deeper into the underground passage, the light grew dimmer and dimmer, until it was almost pitch black.

Chen Feng immediately activated the super-sensory tactical goggles.

On both sides of the passage, one can vaguely see that there is a regular rectangular groove at intervals on the walls. These grooves are all the same size and are arranged neatly, which are obviously places where automatic fire control devices were once installed.

However, at this moment, these grooves were empty. The automatic fire control equipment that should have gleamed with metallic luster had vanished without a trace, leaving only some broken wires and parts, which looked particularly desolate under the blue light.

Chen Feng's gaze slowly swept across the wall...

The further Chen Feng went, the more he could sense the chilling traces of battle.

Those were dense, sharp claw marks and patches of dark brown bloodstains, as if left by some huge and ferocious creature scratching wildly.

There are still many charred marks on the wall.

Some walls were burned black, and some even had holes burned into them.

Chen Feng's brows began to furrow slightly, and a hint of vigilance and seriousness began to appear in his eyes.

The events that had occurred in this passage seemed far more complex and dangerous than he had imagined. The missing automatic fire control devices, sharp claw marks, bloodstains, and burn marks all suggested that this place had once been a battlefield like a purgatory.

If this place is to be activated again, then there must still be deadly weapons remaining here!
