Standing in front of the door and pondering for a while, Du Mu suddenly had an idea and took out something from his pocket.

But it was a key seized from the man in black.

Taking a step forward, Du Mu tried to insert the key into the lock hole, and with a slight twist, he heard a soft click, and the metal door trembled slightly.

Seeing this, he was overjoyed, stretched out his hand and gently pushed, and the metal door opened in response.

The slight crunching sound was very abrupt in the silent passage, and Du Mu hurriedly stopped pushing the door and flashed in through the open gap.

The moment he stood firm, he immediately raised his long sword and looked around warily.

Nothing out of the ordinary happened, and the door was still a swarthy passageway.

However, with the help of the light, you can clearly see that there are many bones and feces scattered on the ground.

Du Mu glanced around and found that many of them were skulls, and from the shape of the beast, they should be some kind of beast, and there were obvious gnawing marks on the bones.

It's home to some kind of carnivorous creature!

With a conclusion in his heart, Du Mu moved more and more cautiously, and walked cautiously inside.

As we progressed, a faint murmur could be heard in the distance.

Gradually, Du Mu found that the sound was actually a burst of shouts and shouts, and it was obvious that there was a battle ahead.

At the same time, light began to shine ahead.

Seeing this, Du Mu put away the lamp shell and walked over with light steps.

At the end of the passage was an oval exit, and by this time, the shouts of killing were already distinct, mixed with the roar of some kind of beast.

Coming to the exit, Du Mu carefully poked out half of his head and looked out.

When he looked at it, he realized that the passage he was in was actually in the middle of the stone wall, and below it was a wide basin, and the battle was staged in the middle of the basin.

On one side were more than a dozen men dressed in black.

With just a glance, Du Mu guessed the identity of the group of people in black, who were undoubtedly the target of their pursuit this time, members of the Black Leaf Organization.

However, what attracted his attention even more was the other side of the fight with the members of the Black Leaf.

A group of kobolds, wielding skeweed creatures with sharp knives and spears.

The moment he saw this creature, a word couldn't help but flash in Du Mu's mind.

Kobold!

He never imagined that he would see this kind of monster in reality that only appeared in strange stories or stories.

"Is it possible...... Is this place a relic?" A question suddenly appeared in Du Mu's heart.

It's only in the ruins where weird things appear that this kind of legendary creature exists, right?

As he pondered, the battle in the basin below had reached its final moment.

There are more than twenty kobolds fighting with the members of the Black Leaf, they have a strange appearance, but their strength is very ordinary, and the combat power value shown in Du Mu's detector is only a little over a hundred.

On the other hand, although the number of members of the Black Leaf is only twelve or thirteen, none of them have a combat strength lower than one hundred and fifteen, and there are even two that exceed three hundred, and they can kill a kobold with a single blow.

Therefore, although the kobold have the upper hand in numbers, they are the inferior side, and it will not be long before they are completely wiped out.

"Those two should be two-star martial artists!"

In the passage, Du Mu stared at the two of them intently, and a trace of doubt flashed in his eyes.

"Strange, how can their combat power fluctuate so much?"

In his detection, the combat power of the two two-star warriors rose and fell, fluctuating extremely much, and when they shot and killed kobolds, they could even break through 350, and once they stopped, they would fall back to more than 300.

After thinking for a few seconds, Du Mu was stunned for a while, and the light in his eyes flashed.

"These two guys are hurt!"

Thinking of this, Du Mu retracted his figure a little back, hiding it more hidden.

Judging from the situation in front of them, it is most likely that after the members of the Black Leaf fled to Guyan Town, they accidentally discovered this ruin, and they were overjoyed to concentrate their people to come in and explore.

And in order to keep it secret and gain time, they brazenly wiped out all the military squads that chased them into the town, and the injuries of the two two-star warriors were estimated to have been left behind when they were fighting with the military squad.

The targets of the elimination also include their squad, but Kuroye miscalculated their strength and was killed tragically, otherwise, presumably the military combat power in the town would have been wiped out by now.

And the market town garrison more than ten kilometers away will not be able to react in at least two or three days, and remobilize combat forces to enter Guyan Town to search.

By that time, I'm afraid that the people of Kuroye would have already fled with the harvest they had gained from the ruins.

"It's a good calculation!" Du Mu sneered secretly, "I'll let you also taste what it's like to be a praying mantis!"

Du Mu, who had made up his mind to be a yellow sparrow, lowered his body more and more, and no longer looked directly at the person with the black leaves, but only paid attention to the battle over there with the corner of his eye.

Although there are harmony glasses, his breath is restrained, and he is not afraid that he will be noticed, but it is better to be cautious.

After all, a martial artist with high perception is very sensitive to malicious gazes, and if he stares at them for a long time, he is likely to be noticed.

Especially since there are two two-star martial artists among the other party, it's better to be safe!

The battle is over soon!

At the cost of three deaths, the Black Leaf side successfully exterminated the more than twenty kobolds, and the rest began to clean up the battlefield, while the two two-star warriors walked to a gate at the end of the basin together and talked in a low voice.

The gate is far more huge and majestic than the one that Du Mu just cleared, with a bright silver body, and many complex electronic circuits engraved on it, full of science and technology.

However, there was a faint gray glow on the door, which made Du Mu feel very familiar, and he thought of a dream for a moment.

He was more and more curious!

Under Du Mu's gaze, a two-star martial artist took out something from his arms, which seemed to be something like a card, and gently pressed it on the electronic screen next to the gate, and then saw the gate snort and automatically separate to both sides.

"It turns out that the purpose of that card is this!" Du Mu said secretly in his heart, "In other words, there are things in there that can increase my strength?"

The gate seemed to allow only one person at a time, and it closed as the two-star warrior strode in.

When the gate closed, another two-star warrior took out a second card and reopened the door.

In this way, the members of Kuroye each held a card and entered the gate one after another.

The basin was quiet again, and only a corpse remained.

After waiting quietly for five minutes, seeing that the gate showed no signs of opening again, Du Mu revealed his figure from behind the passage, used his hands and feet together, climbed down the stone wall with the help of his long sword, and ran towards the gate quickly.

On the way, he stopped to examine the kobold's body.

Except for the hideous head of a dog, they are almost indistinguishable from humans in the rest of the world, and at most their skin is rough and tough, comparable to cowhide.

In addition, after the death of the kobold, the corpse showed no signs of turning into light particles at all.

"It doesn't look like a nightmare creature. Du Mu quickly lost interest, no longer delayed, turned around and ran towards the gate.
