In the woods.

Friday tensed his nerves, holding the miner's lamp on his forehead, shining in the direction of the old yellow dog's barking.

Rustling~

The sound is getting closer and closer, and if you listen closely, you can hear the sound flickering left and right.

At that moment, a large black shadow, completely avoiding the light source, burst out from between the two trees to their right.

"Don't be nervous, it's a police dog." He Zi'an was very calm from beginning to end.

He didn't see anything, but from the barking of the old yellow dog, he could hear that he was warning his kind.

There is a police team stationed outside, and all you can think of is a police dog.

Turning his head on Friday, there was really a police dog under the miner's lamp, not hostile to them, sticking out his tongue.

"You're not a mother, are you?"

He Zi'an bent down and looked down, and was almost squatted on the ground by the old yellow dog.

Then there was another noise.

"He Zi'an, you dare to sneak away from me and come out for me!" Zhang Heng's irritable voice came.

"Lao Huang, take your new boyfriend to lure that fool away, and go back and reward you with a big bone." He Zi'an bowed his head and said.

Friday whispered: "The police dog is here, it's useless for you to run anywhere." ”

He Zi'an woke up when he heard the words and no longer demanded it.

Not long after, Zhang Heng came to spray wildly, risking himself, coming from Min Hai to protect himself, seeing the ground, He Zi'an actually left himself and stole it, not righteous and moral.

"Let the police dog go back and go." He Zi'an didn't want to quarrel.

Then the police dog left, and the three of them moved deeper into the mountain.

At four o'clock in the morning, they came to a stop in front of a cave.

The entrance to the cave is less than half a meter narrow, covered with moss, and covered with weeds, so if you don't pay special attention, you think it's just a relatively large ordinary rock.

Zhang Heng took a flashlight to open the weeds, shone it inside, and said, "What door is this?" ”

"Death's door." He Zi'an replied.

"Can you be serious?"

"I am suspicious, and I have to break my mouth." He Zi'an pursed his lips, then took off his backpack and went sideways into the hole.

The old yellow dog was the second to follow, followed by Zhang Heng, who walked at the back on Friday.

They passed through a narrow area of about ten meters, and the environment suddenly became spacious.

The three of them used their own light sources to probe.

This is a cave, there is not a trace of artificiality, except for the cracks that come in, the walls are tight.

"You're not here to sleep, are you?" Zhang Heng said something that he was embarrassed to say on Friday.

"It's not even as good as Lao Huang." He Zi'an teased.

Zhang Heng wanted to refute, but when the flashlight shone on, he found that the rock wall in front of the old yellow dog was a little damp.

You must know that the whole cave is very dry, at least after a little exploration, I didn't find any traces of water vapor.

"Did it just come out of nowhere?" Asked Friday.

He Zi'an took out a folding sapper shovel from his backpack and said, "Don't talk nonsense, take turns digging." ”

On Friday, Zhang Heng each took out tools from his backpack.

When He Zi'an was digging, the old yellow dog also helped with his paws.

The three of them and one dog worked together to quickly dig a two-meter-deep pit against the ground at the location of the damp rock wall.

"Stop." At this time, He Zi'an called a stop.

Friday flashed to the side and shone with a flashlight.

He Zi'an used the shovel in his hand as a scraper, scraping vigorously against the damp rock wall, and the soil continued to peel off under the force.

Cracks are visible to the naked eye in the rock face.

"No, I thought it was in the ground." Zhang Heng exclaimed.

He Zi'an felt very tired, handed over the work to Friday, got up and said, "If it was the ground, it would have collapsed early if it was dug so violently." ”

Friday was a real kung fu, much faster than He Zi'an, after peeling off the soil on the surface of the rock, he jumped into the pit and dug for the cracks.

Immediately after that, the three of them took turns alternately with each other, digging down seven or eight meters diagonally, and after Zhang Heng took over, the soil suddenly collapsed, and he even slipped into it with a shovel.

He Zi'an and the two of them, who were outside, hurriedly got in when they heard the sound.

But the big yellow dog is the fastest.

Zhang Heng fell into a dark river, did not suffer any injuries, stood up and took a flashlight to shine it and kindly reminded him.

He Zi'an and the others received a reminder that they were basically uninjured and fell into the water after preparing in advance.

Everyone took the lamps in their hands again and probed.

"It's a naturally occurring underground cavern." Said Friday.

He Zi'an nodded and said, "The Jingmen of the first layer of the tomb has now become the Gate of Death. ”

"Don't talk nonsense to preserve your dignity." Zhang Heng took a flashlight and analyzed, "Look at the wind here, you can see that it is coming from the underground river in the distance." ”

He Zi'an bowed his head and said: "It is good to uphold the objective environment, but we must also pay attention to variables. ”

Zhang Heng and Friday bowed their heads.

Under the light in their hands and foreheads, they could clearly see that the water was muddy.

The underground river should have been very clear, after all, there are pebbles and other stones under their feet, but it is so muddy, the only reason is that there is a place to collapse, and the earth is mixed with the water.

Friday looked up and said, "Corresponding to where the wind came from, calculated according to the range... Well, you'll have to take out your compass and look at it. ”

"You're so humorous." Zhang Heng complained.

He Zi'an was speechless, he was a good policeman who was full of justice, so he suddenly became so venomous, and he had to fight everyone when he saw him.

On the side, Friday silently took out the compass.

"Is this the change of Dunjia Eight Gates?" Zhang Heng took a flashlight and shone the compass and shouted.

At this time, the hands in Friday's hand were spinning.

"Don't talk nonsense, we have to stick to materialism." He Zi'an called the old yellow dog and stepped on the water to move.

Zhang Heng followed, complaining: "The three of us are the most like a god stick, and I am embarrassed to mention materialism." ”

"Ah~ I'm sorry, I didn't pay attention, the control valve was not locked, causing the pointer to be confused." Walk in the last Friday embarrassed road.

"Apologize." He Zi'an turned his head and shone Zhang Heng with a searchlight on his forehead.

Zhang Heng pretended to be stupid.

He comforted himself in his heart that He Zi'an was an immoral and black-hearted businessman, and he didn't have to feel guilty.

Three people and one dog, carrying the sound of the wind and stepping on the underground river, walked for about 20 minutes, and encountered a 'wall' and were forced to stop.

"It's really the door of death." Friday walked to the wall, miner's lamp shining and reaching out to caress it.

The wall was made of dirt and rock, and he guessed from the tightness that it would collapse in less than ten hours.

"Is it true that when I say that the Eight Gates Turn is false?" He Zi'an said.

"Didn't you say that you should stick to materialism?" Zhang Heng came to He Zi'an's right side by side, squinting and disdainful.

"Don't think of feudal superstition when you talk about history, and enlightened science when you talk about modernity." He Zi'an looked at the wall and said, "No matter how absurd everything in the world is, in fact, there are rules to be found at the bottom, and if you can find the connection, that is, objective existence and science." ”

"Fallacy!" Zhang Heng snorted coldly.

He Zi'an didn't argue, lowered his head and asked the old yellow dog, and said: "This wall belongs to the northeast at the objective level, right." ”

Woof~

The old yellow dog barked, which meant yes.

"No, it's southeast." On the left, Friday is shaking the compass in his hand.

"The magnetic field here has long been chaotic, otherwise why would I waste time, I have to soak my feet in muddy water, and set the direction as I walk." He Zi'an said.

On Friday, Zhang Heng was dizzy when he heard this, since the magnetic field is unstable, why didn't he say it earlier.

You know, they've been studying the compass to set the direction all the way, and now they think back like fools.
