After Ni Xiaowan got the key, she immediately stuffed it into the lock hole, and after twisting it, the iron tile pavilion under their feet immediately vibrate, and the sound of gears also came from it, when the sound of countless gears was mixed together, it was like a factory in full swing.

At the same time, Tang Qianlin, who was in the water below the iron tile pavilion, also felt the vibration of the pavilion pillar, he turned his head to look over, and saw that the iron chain hanging in mid-air slowly descended, and after descending to the water, Tang Qianlin swam over, grabbed the iron chain, and dived into the water again with the help of the weight of the iron chain.

After diving into the water, Tang Qianlin relied on his previous memories to tie the iron chain to the iron ring, and then climbed up along the iron chain, and after climbing for a while, he shouted loudly towards it: "Reverse the mechanism!" ”

The roar of the iron tile pavilion roof completely overshadowed Tang Qianlin's shouting, and he had to keep shouting there.

Ni Xiaowan was lying on the edge of the pavilion roof, shining a flashlight below, and after vaguely hearing Tang Qianlin's shout, she turned to Qiao Tong and said, "Reverse the key, quickly." ”

After Qiao Tong twisted the key in reverse, the vibration of the entire iron tile pavilion doubled, as if it was about to collapse.

The iron chain also began to pull upwards the boulder at the bottom of the water, and the moment the boulder was pulled up, the water of the underground river immediately poured into it, forming a whirlpool below Tang Qianlin.

Soon, the water in the underground river flowed cleanly down the hole below the boulder.

At the same time, the sound of the mechanism on the top of the iron tile pavilion gradually disappeared, and the entire cave fell into a dead silence.

Tang Qianlin slowly slid down the rope tied to the iron chain, stepping on the river channel below where there was no water and only silt remained, and at the same time, he found that there was light shooting out of the silt of the river.

Tang Qianlin squatted down to dig up the silt and took out a glowing red stone from it.

"Ruby?" Tang Qianlin looked at the ruby and seemed to be different from what he saw on weekdays, but if it was really a natural ruby, then he was standing in a treasure trove at this moment.

Tang Qianlin raised his head and shouted at the people above, "Hey, come down." ”

While waiting for the other four to come down, Tang Qianlin walked under the boulder that had been hoisted, and found that there was a real underground river below, so where was the real entrance?

With the faint light of those rubies, Tang Qianlin searched around, and when he was looking for it, he saw Takahashi Jiro and others holding flashlights walking out of the other end of the river.

When Jiro Takahashi saw Tang Qianlin, he immediately stepped on the mud and ran over with one foot deep and one foot shallow: "Mr. Tang, you are fine, it is really good, there was a shock before, I thought something had happened to you." ”

Qian Sinian saw that Tang Qianlin was fine, and his face was very unhappy.

Immediately after, Qingquan, Jin Gusi, and Yi Mochen also walked over, and Tang Qianlin nodded slightly towards Yi Mochen.

Jinguth walked straight to the bottom of the boulder: "Sure enough, it's the same on both sides. ”

Tang Qianlin looked at Jin Gusi and said, "I think it should be the same, so you also used the same method to open the boulder?" ”

Jinguth nodded: "Yes, what?" Are you surprised? ”

Tang Qianlin was indeed a little surprised, but he didn't expect that Jingusi would discover the problem of the mechanism at almost the same time as him, this Korean adventurer really lived up to his reputation, and he did have some ability.

Jiro Takahashi looked around: "So, where exactly is the entrance?" ”

Tang Qianlin said: "Look for it separately, it must be around here." ”

When everyone was looking for the entrance, Qingquan saw the rubies in the mud, he quickly squatted down and cleaned the rubies out of the mud, and just half after cleaning, Qingquan suddenly remembered the fatal mistake he and his younger brother Qingyu made in the cave in the old expatriate area last time.

Kyung-quan looked at the ruby in his hand and finally threw it back into the mud.

After Qian Sinian waited for Qingquan to walk away, he picked up the rubies that Qingquan threw away and secretly put them in his pocket, he didn't want to go in vain.

They walked around and found nothing, except for the cave under the stone, there was nothing else that looked like an entrance.

Jiro Takahashi squatted at the entrance of the cave and said, "Could it be that you go down from here?" ”

"There is a demon suppression pavilion, then there must be something underneath, where is this thing?" Tang Qianlin looked around, his eyes fell on the mud under his feet, "In the mud? ”

Jiro Takahashi asked, "Why do you say in the mud?" ”

Tang Qianlin said: "There is a problem with these silts, under the premise of turbulent water, the water is not muddy, and you look at the viscosity of these silts. ”

Tang Qianlin stretched out his hand and grabbed it: "It's sticky, like paste." ”

When the two were studying the silt, Qingquan saw Zhang Dagen walking along the river towards the depths, and he hurriedly followed and asked, "Hey, what are you doing?" ”

Zhang Dagen was startled, turned around, pointed to the depths of the river and said, "I seem to see a person standing there." ”

"People?" Qingquan felt strange, picked up the flashlight and shone it forward, and sure enough, he saw a person who seemed to be leaning there in the dark.

Qingquan asked, "Where's your flashlight?" ”

Zhang Dagen shook the flashlight in his hand that didn't light up: "I don't know why it doesn't light up, it's probably broken." ”

"You stand here and wait, don't walk around." Qingquan held a gun in one hand and a flashlight in the other hand and walked towards the depths of the river, and after walking for a long time, he finally saw the so-called figure in the underworld, which was a dried corpse.

There was no doubt that the corpse had fallen into the water after the coffin had been shattered, and that it had been stuck in the crevice when the boulder was lifted, and had not been swept into the real underground river below.

When Qingquan was looking at the dried corpse closely, Zhang Dagen also stepped forward and asked, "Did you find anything?" ”

Qingquan shook his head: "It's just a dried corpse, nothing strange." ”

Zhang Dagen looked at it and said, "But this dried corpse looks so strange." ”

As he spoke, Zhang Dagen poked the flashlight in his hand: "Look, it's so hard, like a stone." ”

Qingquan also stabbed it with a flashlight, and it was as hard as a stone: "When I robbed the tomb in the past, I saw a lot of skeleton corpses, and this is the first time I have seen this kind of appearance, I don't know if it was formed in the coffin of that person, or it was deliberately made like this." ”

As soon as Qingquan said this, he heard Qiao Tong shouting in the distance: "If you find something, you all come here." ”

Qingquan and Zhang Dagen immediately returned to where Tang Qianlin was standing, and saw that Tang Qianlin and the others had dug up the mud under their feet, and under the silt was a stone slab, and there was a human figure sunken into the stone slab.

Seeing this, Jingusi thought for a while, got up and said, "Come and help." ”

After Jingusi finished speaking, he walked quickly along the river towards another cave, and came to the iron tile pavilion of the cave, and also dug up the silt in Tang Qianlin's previous appearance, and sure enough, he also found a stone slab with a sunken human shape on it.

Jinguth smiled: "This mechanism is simple, you can open it by putting the two dried corpses from before into two dented human figures." ”

After Jingusi finished speaking, he got up and looked at Tang Qianlin with a smile: "How about it, I'm faster than you this time, right?" ”

Tang Qianlin stood there silently, just looked at the depression, squatted down to check it, got up again, walked to the hole where the stones were lifted, and thought about something.

The others didn't move the corpse, but stood there looking at Tang Qianlin.

Jinguth was a little dissatisfied: "Hey, why don't you do it quickly?" ”

Qian Sinian came back to his senses: "Zhang Dagen, Qingquan, follow me to find the dried corpse." ”

Qingquan and Zhang Dagen had already discovered one of them, so they quickly moved the dried corpse to Jinguss.

Jin Gusi looked at the people around him who were still waiting for Tang Qianlin: "Mr. Tang probably can't figure out some things, such as why I am one step ahead of him." ”

Qian Sinian ordered again: "Don't be stunned, find out the other one, hurry up, and look for it separately." ”

Ni Xiaowan, Li Yunfan, Yi Mochen and Qiao Tong were indifferent, and after taking a look at Qian Sinian, they walked straight towards Tang Qianlin.

Chance looked at Jiro Takahashi, and Jiro Takahashi didn't say anything.

Qian Sinian asked in a low voice, "Chief Takahashi." ”

Takahashi Jiro ignored him, just walked to the entrance of the cave and stood behind Tang Qianlin, wondering what he was doing.

Ni Xiaowan squatted beside Tang Qianlin and asked, "Master Tang, what's wrong with you?" ”

After Tang Qianlin composed his fixed ruler and fixed wind ruler into the lower phoenix spear, he measured it at the entrance of the cave, then got up and walked to the dried corpse, and measured the height and width of the corpse with the lower phoenix spear.

Jinguth stood next to him with his arms crossed and said, "What do you mean?" ”

Tang Qianlin got up and said, "The diameter of the cave entrance is slightly shorter than the length of the dried corpse. ”

Jinguth smiled: "I know what you want to say, you want to say, dry corpses can't fall into this hole directly, right?" ”

Tang Qianlin nodded silently, and this head caused Jin Gusi to laugh.

Jin Gusi smiled, shook his head and said, "Mr. Tang, have you heard the story of crossing the city gate with a bamboo pole?" You can't get into the city gate with a vertical or horizontal hand, and you're as stupid as the man with the bamboo pole now. ”

The rest of the people were silent when they heard Jinguss's words, indeed, they didn't expect that Tang Qianlin would not understand such a simple truth.

Tang Qianlin shook his head calmly and said: "After the coffin is broken, the dried corpse falls into the water, at that time, the stone has not yet been lifted, the dried corpse will sink to the bottom, even if it does not sink to the bottom, with the turbulent water circulating in the river, it will not last long before it will be stuck, or it will fall into the silt, which is equivalent to being fixed, when we open the stone and the water in the circulating river channel flows into the cave, we cannot take away the two dried corpses." ”

Jin Gusi was stunned for a moment, Tang Qianlin leaned over and picked up a ruby from the mud: "Even such a small stone, falling into the mud, will not necessarily be carried away by the power of the current, let alone such a heavy dry corpse." ”

Jiro Takahashi hurriedly asked, "Then Mr. Tang, what do you mean?" ”

Tang Qianlin looked at the dried corpse and said: "My meaning is very simple, I think this is still a trap, the person who designed the mechanism deliberately wanted us to find the sunken humanoid on the stone slab, because no matter how stupid people are, they will associate this humanoid with those two dry corpses, because it happens to be two dry corpses and two sunken humanoids." ”

Jinguth sneered: "According to what you say, my speculation is wrong? ”

Tang Qianlin nodded: "Yes." ”

Jinguth asked again: "Okay, even if my speculation is wrong, then you tell everyone, what are the sunken figures on these two stone slabs for?" ”
