The underground passage was deep and dark, but there was a faint light.

Flying diagonally all the way down until he came to the bottom, Du Hei muttered to himself at this time.

"This place must be ten meters deep from the ground!"

This is the approximate estimated depth of Duhey.

He flew down an oblique downward path.

Under this inclined slope, it is indeed about ten meters deep from the ground.

But soon, Du Hei was no longer entangled in the depth of this place, but looked around.

This place, at first glance, appears to be a cellar.

At the bottom of the stairs that descended diagonally were some pickled cabbage, as well as other melons and fruits.

But Duhey was not affected by these things.

Controlling the ice sparrow to continue flying, at the edge of the cellar, where the light came out, Duhei found a second iron door in the middle of a pile of crockpots.

Staying in front of the second iron door, Duhai noticed something unusual at this time.

The gap under the iron gate, which should have been extremely tight, seemed to have been dug into a small hole by something.

This opening is very small, almost the size of a fingernail, and it is the appearance of this opening that gives the passage a little light.

"This is a deliberate flow?"

Duhei guessed.

But something doesn't seem right.

You say, this gap seems to be a little too small to allow air to circulate.

Moreover, no matter how you look at it, this place belongs to that kind of hidden hiding place, otherwise this gate would not be under the cover of a pile of melon and fruit bottles.

A small hole flowed out, and the light was still on inside, which was a very silly thing no matter how you looked at it.

"Something, a hole was cut out of here, and it got in. ”

Du Hei made a judgment and carefully investigated.

Then, in the dust on the ground, I saw some fine traces.

The traces are small, barely visible, but rather dense.

"Seems to be ......"

Duhei was wondering what kind of creatures could match these footprints.

At this time, all of a sudden, there was a slightly painful pant sound from inside, and then Du Hei heard a low murmur.

"I'm sorry!"

Du Hei didn't bother to think about it at this time.

Inside, apparently, there are still people.

He controlled the ice sparrow and stepped back a few distances, at which point, the forward one struck.

Bang!

The door shook slightly.

But it didn't move at all.

"Who!"

There was a deep murmur from inside.

Du Hei couldn't answer the words.

At the moment, he is just mentally controlling the ice sparrow.

Bingfinch couldn't speak.

The ice sparrow couldn't open the iron door when it hit it, and there was no way to reply, so it could only break the spiritual link.

Outside, Du Hei got up from the tree and walked towards the tunnel.

After a while, Du Hei came to the iron gate, and then said, "Is there anyone inside?"

After Du Hei asked, a voice came from inside again: "Who is it?!"

Duehe replied, "A passer-by passing through this place. ”

"Found out something happened here, do you need help?"

Inside, no one continued to answer.

But soon, just a few seconds later, there was a click, and the iron door was opened.

The iron door was opened, and under the light, the person who appeared in front of the iron gate made Du Hei startled.

In front of him was a man in his thirties, with a resolute face and dressed in the uniform of an officer.

But at this moment, there were purple markings on his face, and it was visible to the naked eye that these markings continued to spread, covering almost the entire cheek.

On top of that, there was blood flowing from his cheeks.

His expression was hideous, and the veins on his neck were exposed, and at this time, Du Hei saw that he was holding a short dagger in his hand, and there was blood on the dagger.

"This is?!"

Du Hei was about to ask.

The man didn't pay attention to Du Hei, but turned straight away, and then, in Du Hei's puzzled gaze, he walked in front of a person wearing a soldier's uniform and slowly squatted down.

"Need help?"

Du Hei spoke again at this time.

At the same time, the man raised the dagger in his hand and stabbed the soldier in the chest with a fierce blow.

At the same time, panting and muttering, "I'm sorry!"

Originally, the soldier who still had breath, after his heart was punctured, his body naturally trembled and he died completely.

But this approach made Du Hei suspicious.

He looked at the man, strode forward, and was about to ask a question, when the man sat down on the ground, and then suddenly grabbed his hair and began to howl in pain.

"Are you alright?"

The original question can only be converted into an inquiry at the moment.

But at this time, the officer was speechless, just struggled in pain, and twisted his body.

Du Hei was a little dumbfounded.

After a few seconds, he reacted and hurriedly summoned a light elemental elf.

"Light Healing!"

Du Hei hurriedly ordered.

The light elemental elves shimmered with golden light.

The next moment, a flash of golden light gushed out from the golden light elemental elf's body, and it submerged into the man's body.

The man's complexion suddenly softened.

But what made Du Hei's heart sink was that the purple markings on the man's face had not dissipated at this moment.

This markings are obviously abnormal.

Maybe it's some kind of toxin.

Seeing that the man's expression soothed a little, Du Hei didn't forget what he had done just now and asked, "Why did you kill them!"

The man reluctantly raised his head at this time, looked at Du Hei, and said with a wry smile: "I don't want to either." ”

"You take a closer look, their bodies. ”

When Du Hei heard this, at this time, he carefully looked at this secret place.

At this glance, Du Hei's face was even more ugly.

The environment behind the iron gate was not complicated, it was a carved field with a few boxes piled up inside, and there was not even a table, not a chair, only a few straw mats, and a simple room fenced with wood for unknown use.

And at this moment, on the straw mat in the back, Du Hei suddenly saw that there were dozens of corpses, all of which were stabbed to death in the chest after being turned over.

In addition to these dead people, around the man, there were also about twenty soldiers who looked like people, who were unconscious, only slightly breathing.

And the man, apparently, was preparing to stab all of them to death one by one.

As for the reason, Du Hei can probably guess it.

He had noticed that the soldiers, like the dying officers in front of them, had purple markings all over their cheeks.

Moreover, the extent of the spread is even more terrifying than that of the officers, and it has almost reached the Heavenly Spirit Cover.
