The mud under the reservoir was very deep, and Lan Caidie simply took off her shoes and walked forward with her bare little feet. The closer the two of them got to the hole, the more cold they felt. When I got closer, I looked down and saw that there was a big stone under the three-meter-wide water eye, although the big stone could not completely block the overflow of the underground water flow, but there were many ancient charms engraved on it that were still not washed away by the water, but the handwriting was blurry and still unrecognizable.

Wushuang said: "This should have been sealed by a master, can my sister recognize it?"

"I don't even recognize my brother, how can my sister recognize it? But we can't dwell on time, we don't have much time, only three hours, and we'll have to come out when the tide arrives in three hours. ”

Wushuang tied the rope prepared in advance around his waist, and then turned around and gestured to Lu Haotian on the shore. Lu Haotian grabbed the other end and fixed it to an old tree on the shore. The two turned on the flashlight and fell down the rope little by little.

The depth of this underground water eye far exceeded Wushuang's expectations, and the two of them fell little by little, and they were still bottomless for more than ten minutes. In the process of this descent, the geological structure under the entire water eye was also seen. There is a layer of basalt at a depth of about 20 meters below the water eye, and the basalt is hollow, and the cold groundwater flows out of the ground from this layer of space.

Further down are the red sandy mud, which, according to geography, belongs to the four-layer structure of the earth's crust. But seeing that it was going deeper and deeper, Wushuang didn't calculate, but at least it had fallen to a depth of more than three hundred meters now. I don't know when it's going to be a head, but if I don't see the bottom again, the rope won't be enough.

Streams of cold air poured out from under the water eye, and goosebumps rose all over the body of the person who blew it, and even the breath exhaled from the mouth was a white mist. After a few more minutes of falling, the rope was already at the end, but it was still dark and bottomless underneath.

Wushuang raised his head and wanted to say to Lan Caidie, or let's go up and change to a longer one. But when I looked up, I didn't wait to speak...... But when I saw the blue butterfly on the top of my head, the sexy short skirt, the spring breeze under the short skirt was unobstructed, and the big red face of Wushuang hurriedly swallowed the words in his mouth back into his stomach.

"Brother Shuang, don't be cranky, hold on to the rope, look at me!" Lan Caidie's posture was agile, one hand grabbed the rope, and used her toes as a support point to make a beautiful somersault and fell down, I don't know if it was intentional or not, deliberately wrapped one arm around his waist when passing by Wushuang's side.

"Brother Shuang, you have to hold on to the rope! my sister's ninety pound body should be able to withstand it, right?" Her water snake waist rod suddenly stiffened her whole body, and with this strength, she loosened Wushuang's waist, and then spun it, and pierced it with her head down.

"Sister, be careful!"

The girl from the red silk gate is worthy of being a juggler, and her speed is staggering. In this falling process, Lan Caidie used her legs to clamp tightly between the brotch bones of Wushuang, this posture is like hanging upside down on a golden hook, with a difficulty coefficient of 9. 9。

Wushuang wanted to look down to see what she was doing, but as soon as she looked down, the angle of her vision was directly opposite her ultra-short pink little red dress, and the skirt lost its center of gravity and bloomed like a petal......

"Don't look at it!" Lan Caidie laughed.

She took out the end of a hemp rope from her wide cuffs, and the end of the rope did not look long, more than half a meter at most. She tied the short rope with the long rope just now, and then grabbed the corner of the rope and shouted: "Go!" Just look at the rope head, which was originally only more than half a meter long, and it fell down with a whoosh.

Lan Caidie climbed up again and re-fastened the safety lock for Wushuang, and the two continued to dive.

As the altitude was negative, their consciousness gradually blurred. It's not that the darkness around them swallows up their determination, but that there is a limit to how much pressure people can bear, and when they are too high or too low from the surface, the blood supply in the brain will be abnormal, and the reaction fluid of people with insufficient blood supply to the brain will become much duller.

Wushuang only felt that after diving to this depth, he couldn't use the strength of his whole body, and his head was like mush. As soon as he slipped away, his hand gradually lost his strength, and his body fell straight down. Fortunately, Lan Caidie reacted in time, holding the rope with both hands and clamping Wushuang with his legs as he fell.

"Brother Shuang insists on it, and it will be the end soon, or ...... Why don't my sister take you down in this position......? It's just that good brother don't have a nosebleed. ”

Wushuang blushed and hurriedly grabbed the rope and pushed away Lan Caidie's beautiful body.

At that time, they were not prepared, and if there was an altitude meter, then now the meter should show a position of minus four hundred meters above sea level.

Lan Caidie shone it with a flashlight, and there were already white flowers below, and she jumped down as light as a swallow. Wushuang learned her posture and then jumped down, but he didn't know how to work lightly, and the posture of landing was unbearable, but fortunately, there was white sand at the bottom of this water eye.

It was pitch black down there, and you couldn't see anything. The two of them stood still, turned on the flashlight and shone in all directions! Ouch...... The sight in front of me was nothing I had ever seen before, as if I was in a dream.

The two of them were standing in front of a city gate, an ancient city of unspeakable size, with a heavy gate covered with patina, and the walls on the left and right towering and solid. The two gates were silently opened, and the houses and buildings in the city were intact, and not a single brick or tile was damaged. It's just that the beam strength of the flashlight is limited, and the end has been swallowed by darkness.

There is a plaque hanging horizontally on the city gate, which should be the name of this lost ancient city, but it is all in Korean language, and the two do not recognize it.

"Brother Shuang, is there any record in the history of this ancient city?" Lan Caidie asked.

According to historical records, a minority in the north established the Goguryeo regime in the Yalu River and Hunjiang River basins in a few decades BC, and Goguryeo moved its capital to the current Ji'an City in 3 AD. Our Jilin Province has been different several times in history, and it may be difficult to accurately trace the information of this ancient city. ”

The two of them stood in front of the city gate and didn't dare to go deeper, Lan Caidie glanced at her watch, it was already two o'clock in the afternoon, and it took an hour to slide down the rope just now. On the surface, there are still two hours left in the world for the two of them, but if you think about it, the world of falling must be longer than the world of climbing, and if you encounter any trouble and delay time when you go deep into the ancient city, the two of them will have to be drowned and sleep in the ancient city of Goryeo.

The wind was blowing around, and as the wind in the ancient city became heavier and heavier, there were beautiful notes from inside. The two looked at each other, both of them surprised. How is this possible? The ruins of this ancient city are at least 1,000 years old, and there are still living people down there? Could it be that the ancient corpse of Goryeo that jumped into the reservoir is playing the guqin?
