I couldn't tell what that black shadow was, I just thought it was big. Mu Qiang didn't seem to be flustered now, standing in place, constantly moving the flashlight. Probably thinking that the light was not enough, he took my miner's lamp again and shook it together. Under the light of two strong rays, I looked at it for a while, and then I could barely get a rough idea.

It can be said that the scene in front of me is very shocking.

When the huge pile of rocks collapsed, what looked like a wooden building was revealed. That is, the black shadow I saw at the beginning, this wooden building should be eight to ten meters high, and the length of the four sides is also eight to ten meters.

In the front and back of the wooden building, there are craggy white bones everywhere. Sticking to the outermost part of the stone pile, a circle of white bones was arranged in a radioactive shape, and it felt as if these white bones were trying to climb outward, but they were imprisoned by something, and they could not climb out of the area covered by the stone pile.

Even when I was talking to Mu Qiang, the whistling sound mixed with wailing and roaring was still continuous, like a wave, wave after wave.

Just listening to this sound can give you goosebumps all over your body.

"What's that?" I heard Mu Qiang say that there was no big problem, so I was a little relieved.

"Do you see that wooden building?" The light in Mu Qiang's hand has always shone in front and behind the wooden building: "With this wooden building, the things in it can't come out." ”

"I've never seen a wooden building like this."

"It's very rare now, it's a coffin tower, also called a gas tower."

The coffin tower that Mu Qiang said appeared a long time ago, and the earliest history can be traced back to the end of the Shang Dynasty. Actually, this is a kind of evil art, which comes from a group of people called "evil prescriptions".

This group of people has always been very secretive, has no bottom line in doing things, and relies on evil magic to collect money to do things. The prototype of the coffin building is a kind of technique to suppress the corpse and change the transport, using the wooden strips and wooden blocks processed from locust wood to build a model of a small building with equal sides, and then bury it in the grave bag above the surface.

The locust wood is the most shady wood, and if this small building is buried in the cemetery, the family and descendants of the tomb owner will be affected.

Later, the coffin tower continued to evolve and gradually became a magic weapon used to suppress evil spirits. Depending on the size of the ritual, the size of the coffin tower is also uncertain. Most of the coffin pressing tower is said to prevent corpses from degenerating, and it also has a name, called the gas suppression tower, which means to suppress evil qi and yin qi.

I haven't always understood these things, but Mu Qiang is a clear man and told me a lot. Legend has it that in ancient times, in order to show off their martial arts and fight the enemy's faith, the victorious side would generally collect the corpses of the enemy, gather them, and pile them up into a hill-like takakatsuka, which is called Kyokan.

Where there is a Jingguan, there must be a gas tower, which is a secret that is not a secret. Jingguan is thousands of corpses at every turn, and the gas tower is also very large.

The most famous era of the gas tower is probably the Warring States period of the pre-Qin period. Qin and Zhao fought the Battle of Changping, and all the 400,000 soldiers of Zhao were buried alive and killed. Every mass grave that kills and descends will be accompanied by a gas suppression tower. 400,000 people were killed in the pit, and there were at least a few hundred gas towers.

And the wooden building in front of us is a gas tower.

"Those corpses were all disposed of collectively in a premeditated manner." Mu Qiang pointed ahead and said, "It seems that there were masters who gave guidance at that time, and specially built this gas suppression tower. ”

In some cases, there is no need for clues, and one or two can be inferred from just superficial phenomena. This pit is mostly used to extract ore and refine immortal copper, which is top secret, and the hard labor of mining and labor here may not be able to get out alive. The collective death of the hard laborers is piled up here, covered with a gas tower, no matter how strong the yin qi is, it can't turn over the waves.

"These guys are so ruthless." Mu Qiang sighed: "In our old saying, this is what makes people never turn over." ”

The tower, which seemed to be stronger than a solid stone pile, collapsed, but the wooden tower was unharmed. Under the suppression of the gas tower, the faint whistling sound has always been confined to the range where the stone pile is. Mu Qiang said that with this gas tower, there would be nothing, but listening to the whistling sound in my ears, I felt terrible and miserable.

"Mr. Lian, it's not me talking nonsense." Mu Qiang turned his head to look at me and said, "This place, there should be nothing to look forward to, when those mining people leave, they take everything they can take away, and they won't leave any clues." ”

"There's probably not much to see here in the mines." I looked up at the top of the pit, and to the north there was a path close to the pit, like a boardwalk facing a mountain and a cliff. As soon as we arrived, all our attention was on the pit, and it was unknown whether the path would lead or where.

Mu Qiang and I walked through the circular tunnel, then returned to the steep slope we came from, and walked to the edge of the pit to cross the path. The path is very narrow, and it is quite crowded when two people walk side by side. Although the pit next to it is not an abyss, it is enough to choke if you fall. The two of us slowed down, one after the other, and walked down the path to the front.

The path follows the edge of the pit, and after about forty or fifty meters, the path turns north. As soon as I turned the corner along the path, I heard the sound of running water, and about ten meters in front of me, there was a pile of stones, which obviously blocked the path.

This pile of stones is just ordinary stones, and the pile of stones is not large, and it is impossible to hide anything in it. Mu Qiang and I pushed down the top two stones and stood on the pile of stones to take a look.

The path may be at the end, behind the stone pile, there is indeed the sound of the dark river flowing, the underground water system here is relatively developed, everywhere is stagnant water, flowing slowly.

I saw a dark river rushing to the north of the stagnant water. According to my analysis, the underground ancient city is not far from the Ta'er Lake, and we ran here from the entrance of the small cave, which is equivalent to narrowing the distance with the Ta'er Lake.

Is the dark river in front of you the same as the dark river under Taer Lake? If it is the same river, then there must be a connection between the two places, at least to allow the river to flow.

I was in good spirits, and we searched around here for an entrance to the bottom of Ta'er Lake, and now was the opportunity not to be missed, and we had to figure out the dark river.

"Let's take a look next to the river." I rolled up my trousers, and from here to the dark river over there, I had to step through patches of stagnant water, which was not large, but I didn't know how deep.

The two of us jumped down from the pile of rocks, and slowly and tentatively stepped into a pool of stagnant water, which was not up to our knees, but the water was so cold that as soon as we put our feet in, it was unspeakably sore.

After walking forward six or seven meters, the water was deeper, and gradually it did not reach the thighs, and I thought, if we go forward again, the water will gradually become deeper, then we can only swim over, in such an environment, covered with water, the taste can be imagined.

"Enjoyable........" I couldn't help but shiver and smiled bitterly.

"It's cold now, when it's over, let's go back and build a fire, and take two more sips, Hu Gaoshan sticks wine, he must have secretly brought some, let's find him to order, and the whole body will be roasted dry, and it will be comfortable......." Mu Qiang was talking, his expression was cold, he froze for a second, and suddenly pulled me back.

Swish!!!

At the moment when the two of us staggered out, a row of upside-down spearheads emerged from the stagnant water. Although the spearhead is rusty, the force of the bullet is very fierce, and you can even hear the buzzing sound of the spearhead shaking from side to side.

I didn't catch my breath, and I felt my face darken. The place where the spearhead came up was exactly where Mu Qiang and I were standing just now, if Mu Qiang's reaction was a little slower, the two of us would definitely be skewers at this time.

"There's a lot in the water." Mu Qiang gently wiped the water from his face, and even lowered his voice a lot: "Let's slow down, you go behind me, don't move around a step......."

The bracket in the water is a bit more complicated than the bracket on land, because it needs to consider the time that the trigger device is stored in the water, as well as the resistance caused by the water itself. When Mu Qiang used to go into the pit, he had too many times to deal with this kind of machine.

Standing water obstructs the view and makes it impossible to see possible triggers underwater. Fortunately, the structure of this bracket is more complicated, and the trigger is also a chain trigger, from touching the trigger device to the actual effect of the bracket, it takes a certain amount of time in between, if you are an experienced person, you can take advantage of this fleeting time to react.

I followed behind Mu Qiang and walked a few meters away, Mu Qiang shrank back, and with a bang, a row of buzzing spearheads popped out of the turbid water.

"This may be to stop the former slaves from escaping secretly, but it is also likely to stop everyone who wants to cross this stagnant water." Mu Qiang's face was full of water droplets, probably mixed with cold sweat, he carefully bypassed the row of soul-chasing spearheads in front of him, and whispered to me: "These machines look nothing, in fact, they are very bullish, the kitchen equipment is basically made of stones, and it can be maintained underwater for a long time without failing, not a master in this area, you can't create this kind of killing trap........."

I must have been nervous, but at the same time, there was an indescribable excitement. If it weren't necessary, there would be no such thing in this stagnant water that leads to the dark river.
