The more Luo Lie dived, the more surprised he was in his heart, he couldn't imagine that there was such a deep pool under the Old Summer Palace, when he dive to more than 30 meters, a large number of stars and dots of phosphorescence suddenly appeared in the water, Luo Hunt looked at it, the little phosphorescence came from a small fish, the largest small fish was not more than an inch in length, hundreds of thousands gathered together, cruising in the pool, connected into a beautiful long light belt, the fish swam around Luo Hunt, through the light emitted by the fish, Luo Lie saw that there was a two-meter square hole above the pool wall on his right, and there was a green light from the hole。

Luo Lie looked carefully, sure that it was not his own illusion, the light did come from the mouth of the cave, Luo Lie did not rush into the cave, but chose to continue to dive down, the ankle rope suddenly tightened, but the rope had reached the end, but still failed to reach the bottom of the pool, Luo Lie saw that the time was almost up, and did not want to worry his companions, so he chose to float quickly.

Luo Lie returned to the surface of the water, and only six minutes had passed.

The sparrow was naturally overjoyed to see Luo Hunt return so quickly.

The blind man leaned over and said, "What's the matter, I can't hold it back so soon?" He underestimated Luo Lie, Luo Hunt didn't have any sense of suffocation during this time underwater, he had tried in the past, the maximum time he could hold his breath underwater could reach fifteen minutes, after learning the breathing method from Wu Jie, this time should be greatly extended.

Several people couldn't help but be a little worried when they heard that Luo Hunt was going to dive again, although Luo Hunt reassured them, the curiosity in his heart had been completely aroused, and today he must find out what the source of the green light is.

Luo Lie dived again, and before this dive, he insisted on untying the rope and agreed with a few people to fifteen minutes, which was also the limit of his ability to hold his breath underwater in the past.

Luo Lie did not choose to dive deeply, this time the purpose was clear, he went straight to the square cave about thirty meters underwater, successfully came to the front of the hole, grabbed the edge of the hole and swam inside, he set a time in his heart, after six minutes, whether he could swim to the source of the green light or not, he must return, otherwise he would risk his life.

The group of small fish just now came to Luo Lie's side at this time, the fish peeked at this uninvited guest curiously, swam around him left and right, although Luo Hunt saw the green light, but really swam over only to find that the distance was not close, he swam at the fastest speed of about two hundred meters, and found that the green light was still ahead, but the light became stronger and stronger, proving that he was not far from the light source, and there was less than half a minute left before he returned, Luo Lie did not have any sense of suffocation.

Just when he hesitated to move forward, a turntable the size of a millstone appeared on his right, which was made into the shape of a ship's rudder, Luo Hunt swam to the turntable, intuitively judged that this turntable should be a valve, part of the huge underground flood drainage project of the Old Summer Palace, he tried to turn it clockwise, but he didn't expect that the turntable immersed in the water for countless days and moons could still rotate freely.

Luo Lie only turned the turntable for half a turn, and then felt an undercurrent suddenly attacking from in front of him, Luo Lie was caught off guard, and was almost washed out by this undercurrent, and he grabbed the turntable desperately to avoid being swept away by the undercurrent. The impact of the water made his body completely horizontal, and his arms gripped the turntable tightly, but turned it further counterclockwise.

The three of them, who had been squatting by the pool to observe when Luo Hunt would return, almost simultaneously found that the water surface in the pool began to retreat rapidly, and the blind man exclaimed, "Damn, the water has receded!"

Arnold nodded, his eyes widened, the water was rapidly descending at a speed visible to the naked eye, and at this time the kung fu had already dropped three meters, and he muttered, "What did that guy do?"

The sparrow was most concerned about time, there were still four minutes left before Luo Hunt returned, but the situation in front of him made his return unknown, I don't know where the water surface is going to fall, and I don't know where Luo Hunt is?

No matter how worried they may be, the only thing they can do now is wait. The surface of the water began to slow down after a rapid drop of ten meters, and as the minutes passed, they became more and more worried, it had been a full fifteen minutes, and they didn't know if Luo Hunt could support it underwater.

The blind man lay on the edge of the pool, half of his body poked in, he tried his best to see the hole that Luo Lie said, and his little eyes that kept blinking finally saw the green light that Luo Lie said, and the water surface had descended to the upper edge of the hole, and the blind man shouted: "Luo Lie, can you hear it?"

His voice echoed in the inner wall of the hollow pool, and he didn't calm down for a long time, but unfortunately he didn't hear Luo Lie's reply.

Arnold also shouted: "Luo Lie, are you still alive?" As soon as the words fell, he was slapped on the head by a blind man, obviously blaming him for talking nonsense.

The sparrow was almost in tears at the moment.

At this moment, a voice came from below: "I'm fine......"

The blind man and Arnold heard that the voice came from Luo Lie, and the two of them shouted excitedly, but the sparrow cried with joy, and the three of them naturally couldn't imagine what Luo Lie had experienced in the past few minutes.

For Luo Lie, these few minutes were like a nightmare, after he unscrewed the turntable, he was almost rushed out by the powerful undercurrent, only to hold on to the turntable, he was like a fallen leaf in the autumn wind under the strong undercurrent, grasping the turntable and turning around again and again, his limbs were as if he was repeatedly torn by an invisible big hand, and there was no pain in his body, and he struggled in the tearing pain for more than ten minutes, and the water surface in the passage only fell, and he was able to breathe freely.

When the water descended to his waist, he heard the cries of Arno and the blind man outside, and Luo Lie responded loudly so that his companions would not be worried.

The three people above the pool were sure that Luo Hunt was safe, and they were all relieved, but there was a distance of nearly thirty meters from their current position to the hole exposed on the water, and there was water in the pool just now, so they could dive freely, and now they could only rely on ropes to enter it, but fortunately, Arnold brought a long enough rope.

After all the stagnant water in the passage flowed out, Luo Lie turned around and came to the entrance of the cave, grabbed the edge of the hole and looked down, but saw that the water surface had receded to about five meters below, and it was still falling, it seemed that he had inadvertently activated the valve of the pool drainage, and now the water in the entire pool had been quickly emptied outward.

The blind man said: "Luo Lie, don't be afraid, I'll come down to help you." ”

Luo Hunt wanted to stop them from coming down, but at this point the sparrow and the blind man were very resolute, and the two let Arnold guard on it, and descended along the rope one after another, and came to the entrance of the cave where Luo Hunt was, and Luo Hunt stretched out his hand and pulled them in one by one.

Seeing Luo Lie appear in front of him unharmed, the sparrow didn't care that the blind man was still around, and after calling Luo Lie, he pounced on him, hugged Luo Lie tightly and said, "You bastard, do you know that people are worried about you?"

When the blind man saw the scene in front of him, he quickly turned around, Luo Lie was inevitably a little embarrassed, and said softly: "The blind man is here." ”

The sparrow was extremely brave at the moment: "I am not afraid of him." ”

The blind man said: "You are not afraid of me, please find a place to carry me when you two make out next time, have you considered the feelings of a single person?"

The sparrow couldn't help laughing, and then let go of Luo Lie, remembering his unbearable performance just now, he was a little shy at this time, and changed the topic: "What is that green light?"

Luo Lie said: "I haven't had time to see it, I was almost washed out by the water just now." Recalling the scene just now, Luo Lie was inevitably a little afraid.

He took the two of them to the turntable just now, at this time he was able to determine that this turntable was actually the valve that controlled the drainage, just now Luo Lie opened the valve, causing the water in the pool to be quickly emptied, this underwater passage is made of huge stones stacked together, and a layer of silt has precipitated on the ground, although the water has been emptied, but it is still extremely slippery.

The sparrow lit the candlestick, approached the valve, and found a line of French inscription on the valve, both Luo Lie and Sparrow knew French, and from the inscription, it was written on it by Benois Michel.

Sparrow said: "There are many foreigners among the designers of the Old Summer Palace, the most famous of which are the Frenchman Wang Zhicheng and Jiang Youren, this Jiang Youren's real name is Benoit Michel, he was recommended by the Italian Lang Shining, was appointed by the Qianlong Emperor to participate in the construction of the Western building complex of the Changchun Garden of the Old Summer Palace. ”

Luo Lie nodded, during this time, he also read a lot of information about the Old Summer Palace, and knew something about this Jiang Youren, who was mainly responsible for the design and construction guidance of the artificial fountain in the Old Summer Palace. Harmonious Wonder, Water Storage Building, Bird Cage, Yellow Flower Array, Haiyan Hall, Yuanying Temple and many water law projects were completed under his design and auspices, including the fountain of the twelve animal statues in front of Haiyan Hall.

Luo Lie said: "In this way, we should go to the bottom of the Great Water Law." ”

Sparrow said: "It's hard to say now, just by the name of this Frenchman, it is not possible to conclude that we have entered the area under the Great Water Law. She was also a little surprised in her heart, the map that Luo Lie brought before hid several markers, the most important of which was in the Xihai, although they deduced the location of the possible treasure, but the reality was that they could not hunt for the treasure, and today they may have found another way from the flood drainage well of the Zhengjue Temple.

After listening to them, the blind man said angrily: "This Jiang Youren must be a spy sent by France, this thing is ostensibly helping to repair the Old Summer Palace, but he can report to the French behind his back, so there is the disaster of burning the Old Summer Palace later." ”

Sparrow smiled: "You can misunderstand him, Jiang Youren died in 1774, and the burning of the Old Summer Palace by the British and French forces occurred in Xianfeng ten years, and the difference between the two is nearly a hundred years, so it should be unlikely that he reported the news." And I heard that his death was also because of the Old Summer Palace. ”

The blind man was able to penetrate a little, gasped and said, "You mean that the emperor at that time killed him in order to keep the secret?"

Sparrow said: "It's just a rumor, but it may not be true." ”
