"Bang ......"

The leopard bent down and pulled gently, only to hear a muffled sound, and the secret door was opened so easily.

Lu Chen used a flashlight to shine inside, and found that below was a staircase made of cement, about twenty meters long, and as for the depths, it was dark, and it was impossible to see what was in the depths.

"Let's go down. ”

Lu Chen took back the flashlight and said to the tiger on the side.

The tiger nodded and said in a deep voice: "Leopard, you continue to be in front, and for safety, turn the brightness of the searchlight to the lowest." ”

When the leopard heard this, he hurriedly adjusted the small searchlight in his hand, and then took the lead and carefully went deep into the ground along the steps.

"Boss, there's no anomaly down there. ”

It didn't take long for the leopard's voice to come over the walkie-talkie.

After making sure that there was no danger below for the time being, the tiger turned to Lu Chen and the others: "Let's go down too." ”

After saying that, he went all the way down the steps, and Lu Chen and the fox also followed, and the last male lion hesitated for a while, but still followed.

A group of five people slowly groped their way forward in the tunnel, and for fear of some unknown danger, except for the small searchlight in the leopard's hand, the other four had already turned off the lighting equipment in their hands.

And the leopard also turned the brightness of the small searchlight to the lowest, walked in the front, and took Lu Chen and the four of them into the tunnel with a cautious and cautious face.

"It's so quiet, isn't it?"

The male lion who followed behind couldn't help but mutter.

He found that the further he went, the more blurred his eyes became, as if he were blind, and he felt that he could not see anything but the faint light in the leopard's hand.

As he walked, he "banged" and hit the tiger in front of him directly.

"Boss, what's wrong? Why did you stop so well?"

The male lion rubbed his sore nose and grumbled in a low voice.

"Be quiet, there seems to be a situation ahead. ”

The tiger made a "shhhh

He approached the leopard and whispered, "Did you find anything?"

"Boss, we seem to have reached the end of the road. ”

The leopard took the small searchlight in his hand and shone it ahead, only to see a concrete wall lying in front of several people.

Then, he whispered, "Boss, do you smell blood?"

"Huh?"

When the tiger heard this, he twitched his nose a few times, sniffed it carefully, and it seemed that there was really a faint smell of blood wafting in the air.

This sudden smell of blood made him frown, and he immediately ordered: "Fox, put on the infrared thermal imaging camera and see if there are any other creatures around." ”

When the fox heard the order, he quickly took out a head-mounted thermal imager from his backpack, put it on his head, and looked around carefully.

After thoroughly determining the surrounding situation, she spoke: "Big brother, except for the five of us, no other creatures have been detected. ”

Thermal imaging cameras detect objects by their different temperatures, as long as the temperature is higher than absolute zero, they will radiate infrared rays to the outside world, and it is by detecting this infrared that the thermal imaging camera can measure the temperature and generate images.

Animals such as snakes, despite their cold-blooded names, still have a body temperature that can be detected by thermal imaging cameras.

"Turn on the flashlight and searchlight!"

After making sure that there were no other people or animals in the vicinity except for the five of them, the tiger immediately ordered everyone to turn on the lighting tools and check the surrounding situation.

When Lu Chen and the others turned on the strong flashlights and small searchlights, the surrounding environment immediately came into everyone's eyes.

It turned out that they had really come to the end, but in the direction near the right, there was a deep pit that was about two meters square.

In the center of this deep pit, a wooden stake four or five meters high was erected, and the surface was red, like blood. The smell of blood that the leopard and the tiger smelled just now seemed to come from here.

The five of them looked at each other and were almost sure that this was the problem, so they walked towards the pit together.

But before he could walk into the pit, Lu Chen suddenly stopped, making the four people around him look puzzled, and the tiger even asked, "What's wrong, Mr. Lu, is there any situation?"

"It's nothing, I was thinking about something else just now, and I was stunned for a moment. ”

Lu Chen smiled and replied softly.

Seeing that the tiger and the others didn't care, he put his right hand into his jacket and touched the white jade butterfly pendant hanging around his neck. Just as he was approaching the deep pit, this white jade butterfly suddenly trembled and became a little warm, which was why he stopped suddenly.

And as it gets closer to the pit, the more the white jade butterfly flutters, and the temperature continues to rise, and in the end, it almost feels a little hot.

"This jade pendant should have the effect of protecting the master, and at this time, the reaction is so strong, is there something hidden in this deep pit?"

Lu Chen forcibly endured the pain of the jade pendant's burning skin, frowned, and thought secretly in his heart.

"Mr. Lu, the situation here seems to be a little weird!"

The tiger stood at the edge of the pit, looking at the stake that had been erected in the very center, and said gloomily.

As well-known mercenaries overseas, it can be said that the four tigers came across the sea of corpses and blood, and they don't know how much blood they have on their hands, which also makes them no stranger to human blood.

And on the surface of the wooden stake in front of him, the bright and bewitching red color is definitely not a dye or paint, it is completely the imprint formed by human blood after it has dried up. As for why the dried blood stains still remained bright red, then he did not know.

"I'm going down and have a look, what about you?"

Lu Chen was already sure that the reason why the white jade butterfly pendant had changed so much was mainly due to the blood-colored wooden stake in the deep pit, so he was ready to go down and find out.

When the tiger heard this, he was silent for a while, then nodded and said, "I will go down with the leopard, and the fox and the lion will stay on it just in case." ”

After saying that, the three of them jumped down from the edge of the pit and jumped directly into the pit.

When they approached the stake, the three of them realized that the stake was so large that it would take almost three or four adults to hold it. And on the surface of the stake, there are also strange runes depicted, revealing a mysterious and weird feeling.
