Entering from the open rock wall, lighting the brazier inside, at the end of the passage is a boxy stone chamber, there is nothing in it, but in the middle there is a bay pool, what makes me very strange is that this place has been silent for hundreds of years and no one has set foot in it, but the water in the pool is so clear that you can faintly see the dragon pattern below.

The water is not still, it flows slowly and sparkling, and looking down is like seeing a lifelike latent dragon swimming in the water.

"This is endless, I almost put my life on the line, I found here, Qing Taizu didn't want to leave anything behind." The field chicken complained loudly. "What is this, get a pond to raise fish."

"The Dragon Vein Temple is very important, of course Qing Taizu will be extremely cautious, the more cumbersome and difficult it is, the more confident I am in my heart." Gong Jue looked around and said. "Look at the dust deposited here, no one has come since the Holy Palace was closed, although Dolgon found the Holy Palace back then, but unfortunately he failed to comprehend the hint of Qing Taizu, he has been waiting for Dolgon to come here, but he didn't expect that it was us who were waiting."

"It's been hundreds of years here, but why is the water in the pool so clear?" Ye Zhiqiu was puzzled.

"You don't realize that the water in the pool is not stagnant water, and the clarity means that the pool water and the underground river have been flowing, but it is extremely slow and not easy to detect." Turzhan said from the side.

I nodded thoughtfully, and looked at the pool again, this pool is not big but the construction is very exquisite, the east side of the pool is a mighty coiling dragon with teeth and claws, the dragon head stretches out on the surface of the pool, and a stream of clear water is sprayed out of the open mouth, splashing on the surface of the pool and causing a circle of ripples, making the swimming dragon in the pool more lifelike, as if it is alive and playing in the water.

Qing Taizu arranged a lot of mechanisms, leaving this pool in the depths of the mountain, although for the time being, I didn't see what it had to do with the Dragon Vein Temple, but presumably the existence of the pool also played a vital role, but we looked around the pool and didn't find anything unusual.

We carefully inspected the pool boy, Ye Jiuqing stopped at the edge of the pool and looked at the water surface intently and said thoughtfully: "This pool is exquisitely built, and it is in the depths of the Holy Palace, it can be seen that the significance is extraordinary, there is a dragon pattern in the pool water, which should imply the emperor, maybe the entrance is underwater." ”

After Ye Jiuqing finished speaking, he planned to go down to the pool to investigate, Xue Xinrou shook his head and said: "Uncle Ye, look at this pool, it is not shallow, not to mention several meters deep, Qing Taizu hopes that Dolgon can find here, if I were Qing Taizu, how could I not let him dive into the water." ”

"Besides, the pool is crystal clear, everything in it is clear at a glance, there is no need to go down." Bai looked around and nodded. "There is no way out here, Qing Taizu left this pool, I guess it shouldn't be a place to hide the Dragon Vein Temple, there should be other passages here."

"Have you found it, but wherever it is related to the Dragon Vein Temple, the clues left by Qing Taizu are all related to Feng Shui metaphysics." I said thoughtfully beside me.

"Indeed, the construction of the Shengjing Imperial Palace is based on the gossip hexagrams, and the same is true of the Holy Palace, and the Qing Taizu seems to attach great importance to metaphysical feng shui." Bai Jin said.

"The Holy Palace was built in the land of Longsha and Phoenix Crown, it can be seen that when building here, Qing Taizu must have been guided by a master of metaphysics, and he cleverly hid the clues in the feng shui along the way." I said with my chin on my hand and a slight frown. "But the construction of this pool alone is contrary to metaphysics."

"What's the violation?" Tian Ji asked.

"You are a descendant of the Eight Banners, I see that this pool has a Manchurian style, what is such a pool generally used for in Liaodong?" I asked Turjan.

"The Manchu people only have the habit of repairing wells, and do not have the custom of building pools, which is still after entering the customs, influenced by the architectural style of the Han people, there is a pool for viewing, but generally only appears next to the imperial temple in the inner courtyard of the palace."

Turzhan looked at the pool and replied that there are many such pools in the Shengjing Imperial Palace, because under the influence of Buddhism, the pool is used to release animals and pray for blessings, and the harem concubines and emperors will release fish and turtles here in order to pray for blessings.

"I look at the pattern and style of this pool, it is also like a release pool, since the harem concubines will release fish and shrimp in it for blessings, but there are stone carvings of swimming dragons at the bottom of this water." I pointed to the pool and said to the others. "Qing Taizu continues to believe in feng shui, it is impossible not to know what it means to be a dragon swimming in shallow water and being played by shrimp."

"Yes, this is a taboo, even if Qing Taizu doesn't understand, but how can there be metaphysical masters around him who mention it, it's impossible not to understand this, the dragon in the holy palace is the emperor, representing Qing Taizu himself, such a design is clearly suppressing the true dragon emperor." Ye Jiuqing nodded and muttered in surprise.

"But this passer-by, there is no deviation in all the places related to feng shui and earth, it can be seen that everything Qing Taizu does has his intentions, not to mention that this is still the holy palace where the secrets of the Dragon Vein Temple are hidden, Qing Taizu will never make such a superficial mistake, unless the dragon swims in the shallow water here and is played by shrimp, which represents other meanings." I said calmly.

"How else can a pool of water have meaning?" Tian Ji scratched his head.

"If there's no water in this pool, there's a dragon soaring down there." Ye Jiuqing said as he took out the silk cloth in the gold box and pointed to it. "This just matches the wyvern in the clue we found."

"......," I nodded slowly after carefully scrutinizing Ye Jiuqing's words. There is this possibility, that is, as long as the water in this pool is dried up, it will become a trapped dragon soaring into the sky. ”

"That's a big trouble, although this pool is not big, but if the water in it dries up, it will definitely not be completed for a while, and we don't have the tools, it is difficult to hold the water with our hands, and this will take what year and what month." Bai Jin, I frowned and said anxiously.

"Even if we could clean it, I'm afraid it wouldn't be possible to drain all the water in this pool." Gong Jue shook his head and said.

"Why?" Turzhan asked.

"Didn't you hear Chao Ge just now that the water in the pool is crystal clear because the water here is not stagnant water, it is connected to the underground river, and it has been flowing continuously." The palace lord's voice was calm. "Unless the underground river is blocked, it will never dry up."

We all looked at the pool helplessly, and finally came here, but we couldn't find the entrance to the pool.

"Dolgon fortunately didn't find here, otherwise it is estimated that he would be able to die in a hurry, where does he know what kind of organs and metaphysics does he a general, Qing Taizu does so many tricks, wouldn't it be a toss." Tian Ji sighed and said.

"This is a secret related to the lifeline of the Qing Dynasty, not to mention the Jiangshan Sheji, the wealth transported to the Dragon Vein Temple alone is unimaginable, if you are the Qing Taizu, you will casually hide the clues of the treasure?" Xue Xinrou looked at Tian Ji and asked.

"It's Qing Taizu......" Ye Zhiqiu raised his head slightly. yes, what if you put yourself in their shoes? ”

"What do you think of?" I asked.

Ye Zhiqiu frowned and thought carefully for a long time and said, "What if...... If Qing Taizu came here and wanted to move on, because the matter was important and extremely secretive, Qing Taizu would not bring anyone else with him, and if he came alone, it would be impossible to clear the water in the pond with great effort, explanation...... It means that there should be a mechanism to open the entrance nearby. ”

My eyes lit up and I looked around the pool again, and finally my eyes fell on the water jet in the east, we walked over and looked at it for a long time, Ye Jiuqing suddenly said thoughtfully: "Since it is to fly the dragon in the sky, it is necessary that the water here is dry, and this dragon head has been spraying water, is it that the dragon head was deliberately left when this place was built, just to prompt the water to stop the dragon from coming out?" ”

"The water stops the dragon out?" Tian Ji scratched his head and asked. "It's not going to be that simple."

"Sometimes things may not be as complicated as we think."

The water jet sprayed by the faucet was not large, and after I finished speaking, I reached over and a finger could block the waterway in the dragon's mouth, but there was no movement, and I was about to take my hand away, when suddenly my finger touched the edge of the water spray in the dragon's mouth, which was clearly angular and not smooth and round.

I asked Tian Ji to hand me the flashlight, under the light I saw a thin round groove carved in stone in the dragon's mouth, and the water column was sprayed from it, but the groove seemed to be inlaid with something, I buried my head and looked carefully, it was very bright like metal under the flashlight, and I touched it for a moment and frowned and said: "There is a tin package around the groove?" ”

"Tin ......" Gong Jue's eyes suddenly lit up, and he hurriedly took out the tin stick from the gold box. This thing is also made of tin, so you can see if the size fits. ”

I took the tin stick and slowly and carefully put it into the groove of the dragon's mouth, and it was just the same size that I could put it in impartially.

When I inserted the tin stick to the end, I clearly felt the tin stick in my hand as if it had touched something, and there really wasn't a drop of water in the dragon's mouth flowing out, and I found that the tin stick could be turned, and I tried a few times to twist the tin stick clockwise.

Click!

Suddenly we heard a heavy sound in the pool, and then we saw countless blisters rising from below, and a heavy stone wall slowly rising from the right side of the pool, covering the right side of the pool.

Soon we were surprised to find that the water level in the pool was rapidly declining, and I immediately understood the ingenuity of this mechanism, the water in the pool is flowing, the terrain here is low in the west and high in the east, presumably the water of the underground river flows in from the east and flows out from the west, and the rising stone wall blocks the water flowing in, while the stagnant water in the pool can be quickly drained from the west.

When the water in the pool was completely clear, we heard a boom and the dragon ground at the bottom of the water slowly parted in front of us, revealing a deep dark staircase leading to the depths of the earth.
