Chen Fei was about to return to the shore immediately, but everyone saw that the water in the pond was rising quickly. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info then persuaded Chen Fei that after the pool of water was completely restored, it would not be too late to return.

Indeed, if you are not afraid of anything, you are afraid of ten thousand. In this way, it will be safer, even if you fall into the pool, at most you will take a cold shower, which should be fine.

Chen Fei thought about it, and said in his heart that he was not in a hurry for a while, anyway, he had nothing to do when he went ashore. So he stayed on the stone platform, thinking about how to crack the mechanism of the entrance......

......

In a short time, the water level in the pool was basically back to its previous level. So Chen Fei made another move 'Iron Lock Hengjiang' back to the shore, and it still didn't seem to be difficult.

At this time, it was too late for everyone to praise Chen Fei's high kung fu, and now it was better to hurry up and discuss countermeasures.

"It seems that the mechanism of this entrance is not on the stone platform. But ......" Xiao Qian wanted to stop talking, because he really couldn't see any other traps in this underground palace. That's right, there was nothing suspicious at this time, except for a few stone pier-like protrusions on the stone platform.

"Otherwise, let's slam the door......" Hachi said. But in an instant, he realized that his idea was really naïve. Because the stone slab that blocked the entrance was clearly made of the diamond night pearl.

"There must be something wrong...... Chen Fei said......

......

That's right, there is something wrong with the scene at this time. But this so-called 'wrong' is ......, "Alas, ...... this pool?" Ye Qiu said suddenly.

When everyone heard this, they hurried to look at it. But I saw that the wind and waves in this pool were calm, as if there was nothing wrong.

"I mean...... The water in this pool...... Why does it seem to be a ......little fuller than before?" Ye Qiu continued.

After Ye Qiu said this, everyone was a little confused. Because at this time, it seems that the water level in this pool is indeed higher than before, that is, before the water recedes.

Just when everyone was a little puzzled, suddenly Xiaoqian shouted: "Damn, forget this stubble!"

Everyone was puzzled for a while, and said in their hearts, where is this stubble?

It turns out that Xiao Qian means that the waterway in this pool has not been closed at this time, and the water will continue to flow out.

When everyone heard this, they suddenly realized. And as he spoke, the water of the pool had already reached the edge of the pool, and it was about to overflow, and if the channel had not been closed in time, the so-called pool would have overflowed until it had filled the entire Diamond Palace......

......

Thinking of this, Chen Fei hurriedly held the rope again, preparing to lock the river for the third time and go to the stone platform to close the waterway.

But at this time, "It doesn't make sense...... Er Lei said.

Hearing Er Lei say this, everyone was even more puzzled, what did they say in their hearts that it didn't make sense, you couldn't finish it in one go?

It turned out that what Er Lei meant was that, according to Xiao Qian's previous statement, when Da Long went to the stone platform and sat on the bulge with his belly, he touched the three organs under the pool. The activation sequence of these three mechanisms is as follows: 1. The entrance to the stone tablet is opened. 2. The waterway on one of the pool walls was closed. 3. Close the waterway on the other side of the pool wall.

In other words, the channel in this pool was always open. It was the arrival of the great dragon that turned it off.

So, the question arises - why didn't the water in this pool overflow before?!

"Well, yes, that's a real problem...... "Everyone nodded.

"This, this, this ......" Xiao Qian was speechless, because at this time he also thought that this was indeed a problem. According to his previous inference, this Diamond Palace should have been an underground lake thousands of meters deep!

However, his earlier inference did not seem to be reasonable. So it's weird, it's weird, it's weird......

......

"Is it possible...... Could it be that ......??? "Xiao Qian didn't dare to say any more."

"Hurry up, what's the matter?!" Britney urged.

"Is it possible...... Someone came before we arrived?......!" said Xiao Qian thoughtfully.

"What?!Has anyone been here?!!How is this possible?!" everyone said in unison......

......

It turned out that Xiao Qian had inferred that someone had already been the first to climb the stone platform when the people had arrived, and that the first person had already gone to the stone platform and opened the waterways on both sides.

In other words, there was no water in the pool in front of you, or the water was shallow.

And when the people came, the waterway was still open. And when the dragon sat on the bulge, it just closed the waterway.

In this way, the previous inference about the order in which this mechanism was activated is reasonable. And it can also explain why the pool did not overflow, but it was simply because of lack of time......

......

"Hmm...... Makes sense......" the crowd nodded. And he cast an appreciative glance at Xiao Qian, which means that this contemporary Edogawa Conan is really not Sherlock Holmes.

"Hmm, what's wrong with that?" Xiao Qian couldn't help but ask, seeing that everyone was a little skeptical about his reasoning.

"No, not ......at all," Erlei said. What he means is that your inference is reasonable, and it not only confirms your previous judgment of the order in which the mechanism is opened, but also explains why the pool of water did not overflow, and it is indeed flawless.

However, this creates a whole new problem. What about the people who opened the waterways?!

"According to what you say, this person will definitely stay in this underground palace at this time!" Er Lei said resolutely. He was right, everyone went down from the underground palace above, and they walked thousands of meters of stone stairs, and these thousands of meters of stone stairs walked for two hours.

Moreover, there were no forks in the road when I came, and I didn't find any place to hide people. That is, if someone had come before, and had opened the waterway, then he had returned to it before the crowd had come down and left. If that were the case, it would take at least two hours from the time he opened the aqueduct to the time he left.

But what everyone has seen with their own eyes is that it takes less than an hour to fill the pool.

So in this way, the time is not right!

That is to say, if it is indeed as little money inferred, the man who opened the waterway must have remained here at this time......
