The guards quickly arrived at the scene where the demons had fought fiercely.

The scene was a mess, with large areas showing signs of energy burning and heavy attacks.

Two enormous purple hound demons lay on the ground, their bodies resembling shriveled raisins, as if their life force had been absorbed by some mysterious force.

Beside an iron gate lay a humanoid demon—a gluttonous demon on the verge of death.

In Chen Feng's memory.

The second form of the raging demon possessed extremely strong resistance and physical strength. Last time, it took Wei Yang, Xue Nai, and Chen Feng working together to kill it. However, this god of death was now curled up in front of the track wall like a bunch of grapes that had been squeezed dry.

However, at this moment it resembled an old man in his twilight years.

He collapsed in front of the wall, breathing heavily. His once tough body had lost the color of his black skin, revealing the outline of his still slowly beating heart.

Dali immediately took out his equipment and began scanning the Gluttony Demon's body.

"It's a Rank 1 Gluttonous Demon..." the powerful squad leader said in a deep voice.

A look of astonishment crossed everyone's faces...

He was well aware of the strength of a Rank 1 Gluttonous Demon, and even if two squads of guards attacked him together, the Starfish City Guard would likely pay a heavy price.

This is the strength of a low-rank demon. At the same rank, their combat power is almost two minor ranks stronger than that of a human low-rank expert.

The enraged demon's black eyes bulged as he stared at the guards in front of him. His arms, once as heavy as hammers, struggled to point at the iron gate beside him, as if he wanted to say something to them.

"This guy seems to know the whereabouts of 'Main Brand Green Harbor'..." Qu Lu said with a smile.

"The good news is that those demons don't seem to have obtained that artifact yet, but we can't underestimate them. This is a Gluttonous Demon of the Earth Rank, and only Eighth Heaven and Wu Kong in the entire Starfish City are capable of dealing with it alone," Dali said.

"We don't like going it alone."

"Does the iron gate he's pointing to mean we should go inside?" Chen Feng asked.

Qu Lu turned to Chen Feng and explained, "If 'Main Green Harbor' is inside, then we might not find it so easily."

"Why?" Chen Feng asked.

"Because this door leads to the colossal underground city, which is also known as the living coffin of human civilization," Liu Siyu explained.

The Super Beast Dungeon was once the most powerful underground fortress in the Great Xia Kingdom during the Beast Frenzy.

The outermost layer of these underground cities is the "Shock Armor Layer," a basalt shell tens of meters thick inlaid with anti-shock runes that can convert the shock waves from the giant beast's claw strikes into absorbable energy.

The middle layer of walls is made of flowing liquid metal, which provides energy for the repair of the armor layer and can also distort spacetime by activating a gravitational field to ensure that the behemoths cannot detect the existence of the dungeon.

The innermost layer is a regular concrete protective layer.

However, these underground fortresses, which should have been fully utilized, were quickly abandoned by the Great Xia government after the cataclysmic disaster.

The reason was not because resources were exhausted, but because a creature called "weird" had appeared there.

"Let's leave the story aside for now, Qu Lu. As captains of the Starfish City Guard, we can't possibly be afraid of these terrifying legends, right? Besides, if the owner of the 'Main Green Harbor' is really inside, then this is the best opportunity," Dali said.

"These aren't just horror stories; they really exist..."

Qu Lu's voice was low, yet everyone seemed to hear the fear emanating from his heart.

"Qulu, 'Strange' is a legend from three hundred years ago." Dali frowned, seemingly quite dissatisfied with Qulu's current appearance.

Qu Lu didn't answer, but just stared intently at the iron gate.

It was as if some strange sound was faintly haunting things from within...

"Captain Qu, I also think we should go in and take a look. If the owner of 'Main Green Harbor' can survive inside, then it's very likely that he has found a way to fight against the 'Strange'," Liu Siyu said.

Qu Lu glanced at Liu Siyu, but his gaze seemed to contain a complex emotion.

"The 'strange' things do exist..." Qu Lu continued to say to himself.

"Let's go in and take a look. Although this door leads to the dungeon of the colossal beast, we should be fine as long as we don't go inside," Liu Siyu insisted.

"If anything goes wrong, I'll take full responsibility. But Qu Lu, this time even a Rank 1 demon has appeared," Captain Dali insisted.

Chen Feng glanced at Qu Lu.

But the once calm and steady winding road suddenly seemed to have become a different person.

He stood there like a statue eroded by a torrential rain—his exterior maintained a perfect posture, but his interior had long been riddled with holes by a torrent of fear.

Qu Lu clenched his fist so tightly that his fingers dug deep into his palm, and fine beads of blood seeped from the edges of his nails due to the force. His pupils trembled slightly, and even his breathing was broken, with each inhale carrying a rusty, metallic taste.

And that was the rust left by fear in my throat...

After a long while, Qu Lu finally came to his senses in front of Liu Siyu and said seriously, "Then let's go in and take a look. Xiao Song and Xiao Wei, you two arrange the escape route and emergency help devices."

"Understood!" Xiao Song and Xiao Wei replied immediately.

"Chen Feng, I'm entrusting this gluttonous demon to you. I don't want it to cut off our escape route."

"Understood, Captain Qu..." Chen Feng said, a slight smile appearing on his lips.

At this moment, none of the guards knew that as long as Chen Feng killed an opponent stronger than himself, he would gain experience points to advance in rank.

And this is precisely why Chen Feng's promotion speed is so fast!

After the guards began to enter through the iron gate.

Chen Feng glanced at the Gluttonous Demon lying to the side, then quickly drew the Demon Hunter Dagger from his waist and walked up to it.

Looking at these murderers who brutally killed Weiyang...

At this moment, Chen Feng's eyes were filled with nothing but cold killing intent.

He slowly crouched down and measured the demon's vital parts with his hands before finally stabbing it hard into its chest.

Roar!

As the Gluttonous Demon let out its final, unwilling roar, its eyes, which had already turned grayish-white, began to become confused.

Just then, the Lucky Contract System indeed sent a congratulatory message!

(๑•̀ㅂ•́)و✧ A firework suddenly exploded in the center of Chen Feng's vision...

[Lucky Contract: Congratulations, host! You have gained +650 Luck Points for successfully defeating an opponent of a higher rank.]
