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

The guards, who had been searching all along, finally entered the colossal dungeon.

The buildings of this large underground city are like precisely cut iron ore, revealing rough traces of survival everywhere.

The dome of the underground city is made of unpolished concrete, with a surface covered with honeycomb-like holes, like ancient rock layers eroded by acid rain.

Between the different buildings, the passageways were extremely narrow, only wide enough for two people to pass sideways, and the potholes were filled with an unknown black substance.

There are no soft sofas here, only hard benches stuffed with burlap sacks; no bright floor-to-ceiling windows, only tiny vents that let you see only the eternal darkness outside.

The oppressive feeling here comes not only from the physical environment, but also from the complete abandonment of comfort.

"Even people from fifth-tier cities would quickly get tired of this kind of living environment, right?"

As Chen Feng pondered this, he remained vigilant about any potential dangers lurking around him.

However, at that moment, a diamond-like glint suddenly appeared in Chen Feng's vision...

At first, there were only a few scattered pale blue lights, but as Chen Feng gradually approached that direction, those specks of blue starlight suddenly converged into twelve spiral light bands, which quickly intertwined into a pillar of light that shot straight up to the dome.

In the dark space of the dungeon, a projection was also shown, and characters appeared on it.

[Secret Treasure: Earth Leyline Resonance Stone]

Chen Feng was stunned for a moment, then immediately reached out and clicked on the line of text that appeared.

[Treasure Name: Earth Vein Resonance Stone]

[Treasure Grade: Yellow]

[Treasure Effect: Grants permanent vision of any area; usable in any dimensional world; 15 uses]

[Treasure Evaluation: A black pebble embedded in the rock strata; holding it in your hand allows you to hear the "heartbeat" of the dungeon.]

Can this really be considered a secret treasure?

Chen Feng sighed inwardly. In a certain popular mobile game, this would probably be a 5-yuan control ward, right? But having one is better than having none.

However, just as Chen Feng was walking towards the treasure, Liu Siyu called out to him.

"Chen Feng, what are you doing over there?"

"I'm going over there to pick something up..." Chen Feng explained.

"Find something? You're not possessed by some kind of 'ghost,' are you? There's something over there." Liu Siyu said with a puzzled look, and started walking towards Chen Feng.

"No, I'll be right there. Wait for me here." Chen Feng said as he ran towards the location of the [Earth Vein Resonance Stone]. In just a few dozen meters, Chen Feng quickly arrived in front of the treasure.

The "Earth Vein Resonance Stone" looks like just a pebble that is completely black and covered with natural cracks.

However, its blackness is not pure darkness, but rather it emits a faint blue glow from certain angles, as if it has absorbed starlight fragments from the depths of the earth, or as if it has sealed some kind of unactivated energy.

Chen Feng reached out his hand with a puzzled expression, and for the first time put his hand into the reach of the "Earth Vein Resonance Stone".

The next moment, the Lucky Contract system sent another notification.

[Lucky Contract: A secret realm passage has been detected opening. Do you wish to enter the realm, complete the trial, and obtain the treasure?]

[Lucky Contract: "Yes" "No"]

Chen Feng hesitated for a moment before withdrawing his hand from the activation range of the "Earth Vein Resonance Stone".

Everyone is now searching for the whereabouts of the "main holder of Green Harbor". If he falls into a coma, wouldn't he become the scapegoat for the failed operation?

However, at that very moment, a sudden change occurred!

Suddenly, the sounds of fighting and gunfire came from behind Chen Feng, and Chen Feng quickly looked back.

Suddenly, a raging demon and a seductive demon appeared behind the guards.

The enraged demon's scales gleamed like obsidian, its entire body covered in muscles comparable to steel, and it moved with incredible speed, each heavy attack effectively piercing the armor.

The seductive demons are the epitome of high sensitivity and magic. They can always charm those who are not strong-willed, and can even use words to make those they control commit suicide.

To Chen Feng's surprise, despite the guards' impenetrable defensive formation, these two extremely powerful peak Xuan-rank demons were unable to break through it.

Repeated fierce attacks were blocked by the guards wielding the Demon Hunter's Holy Shield and Demon Hunter's Long Spear!

Ho ho ho! ! !

Seeing that their surprise attack had failed, the two demons let out a sharp, unwilling roar and immediately ran off in another direction of the dungeon.

Dali and Qulu exchanged a glance, and the two immediately led their guards, armed with demon-hunting weapons, to follow closely behind.

......

As the last glimpse of the demons vanished into the darkness of the streets, the guards wielding demon-hunting weapons were a step too slow, allowing the two demons to escape their encirclement.

"Damn it, those two bastards got away." Captain Might spat viciously at the ground.

"Captain, look over there!"

Dali immediately looked in the direction his teammate had indicated.

At this moment, a metal statue stood prominently in front of everyone.

The metal statue is 3 meters tall, with a giant dragon head wearing a horned crown, a chest covered with deformable obsidian scales, each scale edged with tiny runic blades, and eyes that are some kind of dark red crystals.

This metal statue is not only covered in defensive metal, but also has dark red quenching patterns on the important attack points.

It doesn't look simple.

"What's this?" Xiao Song asked Liu Siyu with a smile, slinging the Demon Hunter sniper rifle over his shoulder.

"How would I know?" Liu Siyu replied irritably.

"Do you want to know?"

"In no mood..."

"Xiao Song!! What are you doing again!" Xiao Wei pinched Xiao Song's arm angrily, punishing him forcefully.

Just then, Qu Lu, who had been silent all along, spoke, but his tone was serious.

"These statues are called Soul Statues. They were originally powerful golems created by the Great Xia Kingdom government to fight against invading behemoths. However, later on, these golems were used to fight against warriors corrupted by the 'weird'."

"Qu Lu, I thought you didn't know?" Dali said in a deep voice. "You're so young, how could you know these things?"

Qu Lu's expression seemed to dim for a moment, as if he had remembered something that made his life seem gloomy as well.

However, Qu Lu's next words reached everyone's ears like a gentle breeze.

"Because my great-grandfather used to live here..."

Dali sighed and shook his head with deep feeling.

Just then!

As if in response to the history Qu Lu had recounted, a dark red energy ripple suddenly appeared in the silent air!

The dark red eyes of the metal statue suddenly lit up with a blood-flame-like light, and the obsidian breastplate shimmered with a flowing, eerie glow. The entire metal statue seemed to be undergoing some kind of charging process, and its body outline was sketched in the darkness as blue lightning like a spider web.

Boom! Boom! Boom! Boom!

All the guards couldn't help but change their expressions.

Because they could clearly sense that the metal statue before them contained a power they could not resist!
