The three of them continued to walk forward, and the green light became stronger the more they walked. The blind man couldn't help but squint his small eyes. The reason for the strong light was that their eyes were used to the dark environment. Luo Lie looked up and saw a huge green ball in front of him. The light was emitted from the green ball, and the diameter of the green ball was about three meters. Luo Lie thought it was something like fluorite, but later he thought that fluorite should not shine on its own.

When I came to the front of the green ball, I saw mountains, rivers and rivers engraved on it, but it was a huge globe. The globe was carved from the full picture of Kunyu. Jiang Youren presented the full picture of Kunyu to Emperor Qianlong, which made Longyan happy and was valued by Emperor Qianlong. Later, he presided over the drawing of the "Thirteen Rows of Qianlong". It should be said that this person made extremely outstanding contributions to the development of Chinese geography.

The blind man looked at the huge globe and his face turned green, and he praised: "Damn, what a big night pearl, it's worth the money."

Luo Lie thought to himself, it was still unclear whether this was a night pearl, but it may have existed underground for a hundred years. It is inevitable that it can emit light for such a long time, and it must be extremely rare and extremely precious.

The blind man walked around the huge night pearl and thought about how to transport the night pearl back, but soon he realized that there should be no possibility of transporting such a big night pearl out.

The sparrow noticed the topographic map on this green ball. There were several obvious black lines on the topographic map. Luo Lie also noticed this. He carefully identified it and found that these black lines originated from the location of Kunlun Mountain.

The sparrow said: "This should be a dragon vein!"

The blind man is quite accomplished in Feng Shui. He couldn't help laughing when he heard the sparrow say this: "There are twenty-four dragon veins, and each dragon vein symbolizes the emperor for a long time. Do you want me to point it to you?"

The sparrow said: "Sumer Mountain is the bones of heaven and earth, and the middle is a huge thing. Like a person's back and neck beam, the limbs are born with a dragon abrupt. The limbs are divided into four worlds, and the north, south, west and east are four schools. Kongtong in the northwest tens of thousands of journeys, and the east three curtains are dark. Only the southern dragon enters China, and the fetus tribes are strange to the ancestors... "

The blind man was stunned when he heard this. Of course, he was familiar with the mantra he recited by the sparrow. This is the "Dragon Shaking Sutra" written by Yang Xiaosong, a Tang Dynasty man. Yang Xiaosong is a master of Feng Shui. In his writings, he believed that all the Eurasian veins originated from the Kunlun Mountains. Except for the Himalayas and Tianshan Mountains, other mountains are continuations of the Kunlun Mountains. He believed that the dragon veins are the Kunlun Mountains. The Kunlun Mountains are divided into four dragons in the east, west, south, north, and south, east, south, and south, and east to northern India. The north dragon goes directly to the Alps, and civilization is nurtured between dragons or on both sides.

However, it is more widely circulated in China, and the twenty-four dragon veins are relatively few people who know about Yang Xiaosong's dragon veins. The blind man did not expect that the sparrow would be so familiar with the "Shaking Dragon Sutra". It turns out that the dragon gives birth to dragons and phoenixes, and the mouse's son can dig holes. Ma Boxuan, the daughter of a famous archaeologist, is also well-known and knowledgeable.

Luo Lie didn't know much about these aspects, and only after listening to their explanations did he understand. However, the theory of dragon veins was mysterious. He never believed that dragon veins were related to the rise and fall of the dynasty.

When the three of them studied this green ball, the green light emitted by the ball began to decay quickly.

The blind man couldn't help but scream. The big ball had been in the ground for so many years and its light remained undiminished. Unexpectedly, as soon as they arrived, the ball quickly dimmed. Luo Lie did not think it was their reason. The attenuation of the light of the ball should have a direct relationship with water. The big ball was soaked in water just now. Its light was probably because of the interaction with water. He opened the valve and discharged all the water inside. The big ball lost the environment for water soaking, so it lost its luster and quickly dimmed.

Sure enough, the green ball had become dull after a while, and it turned from the green color that was just now to the turquoise. Now it looks like an ordinary stone ball.

The blind man reached out and patted, confirming that the big ball should be solid.

But the sparrow said, "Don't touch!"

The blind man hurriedly took his hand away, but saw a golden pattern appearing on the big ball.

The sparrow immediately saw that the big ball appeared on the structure of the waterway below the Old Summer Palace.

Luo Lie saw that although the changes on the green ball were magical, it was essentially nothing more than a chemical reaction. I don’t know what material this big ball was made of. After the water was shining and the accumulated water receded, the big ball itself reacted with the air again. The structure diagram hidden on the ball was exposed. It was not complicated to figure out the principle, but those who could design this big ball must be extremely intelligent.

The sparrow said: "This place is not far from the Tin Sea. Another treasure place indicated by the treasure map Zhou Xiaodie gave you should be below the Tin Sea." She pointed to the front left.

The blind man walked over quickly and saw a pipe with a diameter of about one meter. He looked down at it and saw that the pipe was deep and could not see it.

The sparrow was full of courage at this time, holding a candle and crawled into the pipe first, singing: "From here, go straight for about 300 meters to reach directly below the Tin Sea, where there should be a drainage center that was washed away by the rapids just now." In a short time, she had forced herself to remember the sewer structure diagram depicted above the green ball.

Luo Lie said with concern: "Slow down." He also crawled in with the sparrow.

The blind man fell to the end. After all, he was bloated, so crawling in such a pipe was extremely difficult for him.

The pipeline was still wet. Before Luo Lie opened the gate, there must be water here. The sparrow was the first to drill out of the pipeline and found that there was a vertical shaft here. Although there was still some water in the well, it could barely flood their ankles. Looking up, the shaft must be at least fifty meters, with a sealed top and a winch on the ground, which was almost exactly the same as the turntable where Luo Lie triggered the drainage.

The sparrow pointed to the top and said, "There is a passage twenty meters above, reaching directly below the Fuhai."

The blind man looked up and saw that the surrounding well walls were extremely smooth and could not find anything to climb. He shook his head and said, "We can't climb up this."

Sparrow said: "It's true that I can't climb up now, but if we open the water inlet valve, we should be able to get there with the help of the buoyancy of the water."

The blind man looked down at the winch and said, "You mean, this is the water inlet valve?"

The sparrow nodded and said, "Not bad! According to the structure diagram of the underground water network I just saw, this should be the water inlet valve. If it is opened here, the drainage valve just now will be closed and the water will flood here again. As the water level rises, we can float upwards and enter the passage twenty meters. Along that passage, we can go directly to the underground palace below the Fuhai."

When they heard the word "District Palace", the blind man and Luo Lie looked at each other at the same time. The underground palaces in the sparrow's mouth were probably what Ye Qinghong said. Although all the signs indicate that there is a treasure hidden under the Old Summer Palace, they did not expect that the treasure land was so secret, and it was so closely related to the complex underground water network of the Old Summer Palace.

When the blind man heard that the secret hiding was close to him, he was inevitably excited. He walked forward to unscrew the water inlet valve, but Luo Lie said, "Have you ever thought about how we can get out?"

The blind man was stopped by him. The drain valve was located on the other side, about 100 meters away from here. If you want to leave the original path, you must start the drain valve first. He cannot guarantee that he can complete this before the oxygen is exhausted.

Luo Lie was worried that this was not the case. It was the position where the water surface would rise after opening the water inlet valve. If the water surface kept spreading through the passage above, it would be isolated from the air here. Among the three of them, they might be able to swim back. It is impossible for the blind and sparrow to hold their breath under the water for so long.

Luo Lie said: "It's better for you to go back first, I'll go up and take a look."

The sparrow shook his head and said, "Can you remember the structure diagram of the water network? Do you know what to do next?" She pointed to the top and said, "The well in Zhengjue Temple should be much higher. I believe that even if the water level reaches the highest, it will not be possible to touch the top. In other words, we can all have the chance to breathe." She paused and said, "Actually, there is no need to go back and open the drain valve. As long as we enter the channel above, there will be drain valve inside."

Luo Lie showed an admiring look. In a short period of time, the sparrow not only understood the waterway structure diagram, but also clevered the key points in it. This memory alone made him feel inferior.

The blind man said, "How can you get a tiger's son if you don't enter the tiger's den? Fuck it!"

The sparrow smiled and said, "I can see that picture very clearly. In fact, there is more than one way out, so we should not have to go back."

Luo Lie saw that the sparrow showed such confidence, which proved that she must be sure. Since that was the case, she might as well follow her guidance, so she asked the blind man to call Arnold in first. Since she decided to continue moving forward, she could not leave Arnold there alone. Once the gate was opened and water was released, it would be equivalent to cutting off the connection with Arnold.

After the four of them met again, they started to work together and twisted the valve counterclockwise. After three weeks of rotation, they felt their feet sinking, and then the water level below rose rapidly.

Because the water flow poured in from below and they were in the shaft, the impact was not large. The four of them kept stepping on the water, and the rise of the water surface gradually led them to a higher place.
