Chapter 185: Aura fluctuations across the dark river

The middle of the tukang is a small secret tunnel. There is no light in it. Yang Yiyun's spiritual sense can only be released for nine meters, and there is nothing suspicious within nine meters.

The two walked in, the inside was narrow and dim, but for Yang Yiyun, the spiritual sense was not affected at all.

The tunnel here is different from the one I found when I came in before. It seems to be an independent tunnel. After several tens of meters, there is no fork in the road, and the terrain has been extending downward at a 30-degree slope.

Yang Yiyun and Qiu Yun use spiritual consciousness to exist in the dark tunnel, and it will not affect them, and they will go straight ahead...

After walking for about a kilometer, Yang Yiyun's spiritual consciousness suddenly found that the space suddenly became larger, and there were no traces of artificially excavated tunnels behind it, and it completely turned into a natural cave.

A 30-degree incline and nearly a kilometer down, if converted, is equivalent to about 300 meters vertically, which means that they have reached a place close to 300 meters underground.

According to the geographical environment, the primary loess of the Loess Plateau is aeolian deposits under the dry and cold climate conditions of the Quaternary Ice Age, and the secondary loess is transformed from the primary loess through flood and alluvium. During the accumulation period of the Quaternary loess, with the glacial age , The climate cycle of the interglacial period, the loess layer presents the alternation of loess and paleosol.

It is also one of the areas with the most serious soil erosion and the most fragile ecological environment in the world. The terrain slopes from northwest to southeast. Except for many rocky mountains, most of it is covered by thick loess, which has been eroded strongly for a long time by flowing water, gradually forming thousands of gullies. A special natural landscape with vast valleys and fragmented terrain.

The landform is undulating, and mountains, hills, plains and wide valleys coexist. Surrounded by mountains, the Loess Plateau is rich in coal, petroleum, bauxite and other resources. It is also an important energy and chemical base for China. Loess has fine grains, soft soil, and rich mineral nutrients, which is conducive to farming, and has a long history of farming in basins and river valleys.

Except for a few rocky mountains, the plateau is covered with a deep layer of loess. The thickness of loess is generally between 50 and 80 meters, and the thickest is 150 meters to more than 200 meters.

In other words, they had already broken away from the thick layer of loess at this time, and the karst caves that appeared now were all composed of grey-blue rocks.

Yang Yiyun easily tested the hardness of the rock on the cave. It should be some kind of rare mine. He didn't expect that there would be a tunnel deep into the ground here, which directly penetrated the loess layer and reached the rock cavern under the ground.

Except for the narrow passage that came down at the beginning, this place is entirely a natural trace, and it should be a karst cave formed countless years ago.

I guessed in my heart that perhaps the Great Northwest was also a big ocean during the Ice Age, but after countless years of crustal movement, the sea dried up, and the melting of glaciers turned it into the Loess Plateau.

The karst cave here may be the real landform of a certain stage in the Northwest in a long time ago.

Yang Yiyun wanted to come here. The secret road may have been there many years ago. It was discovered from the time when Qiu Yunzu was a bandit, and it has been discovered by Chen Baiwan now. It is not known whether this is a storage place or another escape route.

If it was an escape route, would Chen Baiwan already escape?

The terrain here is gentle, the whole cave is a little wet, and the height and width are about four or five meters.

After walking for about a few minutes, Yang Yiyun suddenly heard the sound of water flowing in his ears.

The first reaction is the underground river.

Standing in place and listening, it turned out to be the sound of water, and it was not too small, it should be a big underground river.

Someone seemed to hear footsteps and voices, several tens of meters away.

With a heart move, Qiu Yun speeded up the pace and rushed over.

There was light in the realization without taking a few steps, and it was indeed a human being.

From a long distance, I saw three figures with flashlights in their hands. Not far from the three of them was a dark river with a width of more than 20 meters. There was a modern inflatable boat on the bank, which seemed to be moving things on board.

At first sight, these three Yang Yiyun were acquaintances.

One man and two women, the man is Chen Wanwan, one of the two women is a woman who has stolen love with the old blind man, and the other is the female killer Wang Yilin who has killed Chen Baiqian for the first time.

"Hurry up and get the gold and gems, don't bring the others~" Chen Wanwan's voice revealed anxiety, as if he was running away in a catastrophe.

Indeed, he was frightened by Yang Yiyun today. From the moment Yang Yiyun slashed Ma Xingtian’s head, he knew that he was invincible. Although there was an old blind man who used poison at the time, Chen Baiwan and the old blind were not the same. Harmony, not daring to put hope on the old blind man, so he ran away from the tunnel in the inner room.

After entering the dark tunnel, he hurriedly found his two women through the dark tunnel, preparing to take their wealth accumulated over the years to escape from the dark river.

Ever since he accidentally learned that there are treasures left by bandits a few decades ago, Chen Wanwan has been searching for it. Shao Qiuyun's parents only got the news that the treasure was in an underground cave and didn't know the specific storage.

After searching for more than ten years, I almost dug the underground tunnel of the karst cave three feet into the ground and found no treasure, but found a road leading directly to the outside world. It can go directly to the vicinity of Qing City along the underground river, a very hidden one. escape route.

After development and construction, a small boat can swim. Today, Yang Yiyun killed the door and he could only escape from here. What he took with him was the wealth stored here.

Yang Yiyun gave Chen Baiwan the feeling that he was an evil star, too evil. He couldn’t guarantee that the old blind man would take Yang Yiyun, nor could he guarantee that Yang Yiyun would escape from the old blind man’s hands, and then found the secret path to catch up with him, so he very worried about.

I always feel dazed.

In the distance, Yang Yiyun saw that Chen Wanwan and the three were moving things and preparing to escape, and sneered, then jumped up and stabbed in the past.

Just like Chen Wanwan, who was lucky enough to escape from the claws of an eagle, he was very vigilant. When Yang Yiyun shot a sword, he felt the wind in the air was wrong, and suddenly turned his head to see that it was Yang Yiyun who stabbed him with a sword, scared. Shaking all over.

Seeing Yang Yiyun's sword approaching, it was too late to avoid him. He was not sure to take Yang Yiyun's sword, and he happily took the woman next to him for fear of hitting it out, and met Yang Yiyun's sword, and then threw it without looking back. Jumped into the dark river.

"Puff~ah~"

After Yang Yiyun stabbed with a sword, he didn't expect Chen Wanwan to make such a shameless decision to slap the woman who had stolen love with the old blind man as a shield. Suddenly, this woman was killed by him with a sword.

And the decisive Chen Baiwan jumped into the dark river and escaped. At this time, Qiu Yun said loudly: "Mr. Be careful~"

Without Qiu Yun's reminder, he felt the sneak attack behind him and took advantage of the situation.

"Ding~"

"Ah~"

But it was Wang Yilin who stabbed him from behind with a sword, and Yang Yiyun directly cut the sword in her hand with a sword, and slashed her with a single sword.

So far, both of Chen Wanwan's women had died under Yang Yiyun's sword, but Chen Wanwan jumped into the darkness of indefinite darkness.

Seeing the deep underground river rising without waves, Yang Yiyun didn't jump into the water to look for Chen Wanwan. This is an underground river, and there are no creatures in it. You can't take risks in unknown places.

Besides, whether Chen Wanwan can survive by jumping into the dark river is still unknown. He will watch on the shore, if he comes out of the water, he will be killed. If he does not come out, the chance of surviving in the dark river is in Yang Yiyun's opinion. It's also very small.

Looking at the two women who had died under his own sword, Yang Yiyun sighed and shot out Zhenyuan Lihuo and burned their bodies.

In fact, he didn't want to kill women in his heart, but Chen Wanwan hit the first woman and hit his sword.

The second woman, Wang Yilin, was about to assassinate him. She swung a sword and beheaded it.

Hearing Qiu Yun's footsteps in the distance, Yang Yiyun waved his hand to tighten the four boxes of the inflatable boat. He didn't want Qiu Yun to see the secret of his use of the universe.

I heard Chen Wanwan talk about gold before, and thought that the four boxes should be Chen Wanwan's accumulated wealth. Don't let this kind of windfall.

After Qiu Yun came over, the two picked up the flashlights on the ground to check the surface of the dark river to see if Chen Wanwan would come out!

Only after waiting for more than half an hour, a waterside in the underground river did not rise.

Yang Yiyun walked around the edge of the dark river in order to find Chen Wanwan's trail. At a certain moment, he was standing on a relatively high place. Suddenly, a faint aura fluctuated from his spiritual consciousness.

A flashlight in my heart shone through, but it was discovered that there were spiritual fluctuations in the direction of a mountain wall on the opposite side of the dark river.

The opposite side of the underground river seems to have a lot of space, and the cave rock is completely black as ink, and it looks like an endless dark space from a long distance.

At this moment, a flash of lightning flashed across Yang Yiyun's mind, remembering the two love poems that sister Qiu Yun had read before she died.

Love is in the flowing water, love is the flower at the end of the other shore!

Is it related to treasure?
