Only then did the guards react, the stone surface of the marble could not be infinitely large, there must be a connection between the stone surface and the stone surface, as long as it was connected, there must be a seam, and if there is a seam, a sword can be inserted, and a sword can be inserted to pry out the mechanism.

But having said that, it's still at the bottom of the lake in the middle of the night, have you ever considered the problem of sight? It's not that the dark guards are slow to react, it's really Chi Si's suggestion is very good, the operability is too poor, the blue guards are in the water, and the underwater lighting is not impossible, the night pearl is the most effective, but this thing is really expensive, the whole team of the blue guards only share one, and it must be who has a task and who applies, and today I also bring it, but if you want to find something, you can only use it alone.

What's more, at the bottom of the lake now, the lake mud is connected with moss and aquatic plants, and the dark guards have cleaned it up for a long time, but they only barely let a small piece of white marble be exposed at the bottom of the lake, and the blue guards who take the night pearl are carefully looking for the joints of the stone surface.

The stone is white, almost a sight to see, but within three meters of this, Zhong Xiaoxin repelled the water, so the guards were able to lie on the ground while cleaning up the lake mud, and observed it carefully, fortunately the marble is not white marble, it is rarely pure white, and the marble is textured.

Although the marble at the bottom of the lake and the lines are all connected, if it is usually in the water, the waves are sparkling and the water and the sky are the same color, and it is impossible to see the difference when the line of sight is blocked, but now there is no water in the mechanism, and the stone cracks that are almost invisible are not without a shape.

Looking carefully, you can still find that the stone face is indeed as Chi Si said, piece by piece.

It's just that Chi Si thought that every stone face would be very big and difficult for people to move, so he asked the blue guards to clean up the surroundings of the mechanism, but in fact, Lan Wei, who held the night pearl, found that each stone face was not big, and the stone face was smaller than expected, and it was so small that it could even be said to be very small.

One palm can be covered.

By opening the large hands of an adult man, he can cover a single stone face, each of which is a square with a side length of 20 centimeters in modern terms.

Relying on the fact that there was no water in the middle of the lake at this moment, Lan Wei boldly ripped off the fish dart and reported like this, experiencing the refreshing feeling of shouting wheat under the lake, and other people could hear it, so they invariably looked at Fengyan's feet.

At the beginning, it was inferred that stepping on the mechanism may be related to weight, and it is limited by the weight, and it is not enough to step on the false mechanism without a certain weight.

So the dark guards were all carrying stones of different weights, but the blue guards, who had more weight before, walked over there and didn't step out of the mechanism, but were stepped on by the wind and words.

Water-based hands aren't innate, but they can't all be nurtured, and sometimes genes do distinguish each individual's talents. In Lan Weizhong, the selected water masters generally have more people in two regions, one is near Jiaodong, near the sea and fierce, and the other is Jiangnan people, who grew up in the water town and are flexible.

Shandong people have always been tall, while Jiangnan people are smaller.

Feng Yan is a native of Jiangnan, the shortest in Lanwei, and his feet are naturally small.

That is to say, Feng Yan can step on the mechanism, not because he is heavy enough, but because his feet are small, and other people, or step on the intersection of two stone faces, even if they occasionally step on the center point of the stone face, because their feet are large, they will also step on other stone faces, only Feng Yan may just step on a whole stone face, and just step on the mechanism.

Chi Si also figured it out, sighed, and nodded, the previous "Hello White Bone" was quite short, the old marquis who was the first knight of the Zhong family was a native of Jiangnan, but Chi Si did not consider his figure, and he took a detour in his thinking, if it weren't for the fact that Fengyan's feet were smaller than ordinary men, according to Chi Si's suggestion, it was likely that the blue guards would have been tossing around with stones on their backs for a whole day in vain.

However, even so, everything the dark guards did just now was done in vain, and the place that really needed to be cleared was the place where Fengyan stepped on and was surrounded by stones, and this place was just not cleaned up.

At this time, if you go to clean up, you have to move the stones first, which are heavy stones that weigh dozens of pounds each.

Zhong Xiaoxin couldn't hold it for so long, shouted "Pay attention to the water", her mind was relieved, and the lake water poured into the vacuum area she had just made before, Zhong Xiaoxin was soaked in the lake water again, and the whole person felt healed, it was better to have her own kennel.

Of course, because of the backfill of the water, the previous area of about three meters, the flowing lake water poured in again with the silt at the bottom of the lake, and the marble that had just been cleaned up was covered again.

A group of people could only drive the stone away again with full speed, and only after the stone was removed did they clean the stone face under Fengyan's feet. But the stone surface is the mechanism, not to mention a group of people at the bottom of the lake with their hands to pick up the mud, that is to pick up a piece, the water next to it with the mud backfill a piece, one accidentally touched the stone face in the process of cleaning, and there are hidden arrows shot out.

The men who pick up the mud, whose spirit is also on the verge of collapse, but Zhong Xiaoxin really doesn't have the physical strength to drain the water again at this time, since she started to cultivate immortals, all the power comes from water, and she is still receiving the healing of water, the only thing Zhong Xiaoxin can do is to control the flow of water, and not let it flow back to its original place when it is dialed.

In this way, a group of people carefully picked up mud and dodges, but fortunately, the area of each stone face was not large, and the stone face that Feng Yan stepped on was cleaned up. Lan Wei, who held the Night Pearl, stepped forward to take a closer look, and soon, the complete stone line of the stone surface that Feng Yan stepped on under his feet was also drawn.

Lan Wei begged for a living underwater all the year round, and there were many skills that others didn't know, for example, Zhong Xiaoxin thought it was very good for Lan Wei to take out something that could draw lines.

"What, you have a good thing, take it and bring it over, you can see if the mechanism under his feet can be solved, and then make a reservation from the same place, and tell them to go up and bandage it quickly" Zhong Xiaoxin said.

When Zhong Xiaoxin said this, the blue guards all looked at her in surprise, and Chi Si also had the same expression, but he opened his mouth and didn't speak. The only two of them could speak normally under the Hengzhu Lake, and Zhong Xiaoxin was the boss of a group of people, so Lan Wei did so.

The blue guard who held the night pearl saluted Zhong Xiaoxin first, and then squatted down to carefully observe the mechanism under Feng Yan's feet.

The mechanism is actually very simple, the stone surface was gently stepped into the bottom of the lake by Fengyan, and the four corners of the collapsed iron cables poked out of each other to form a "#" shape, buckling the feet. Just push the rope aside.

So the blue guards dodged seven or eight rounds of small dark arrows, so that the blue guards holding the night pearl freed Fengyan's feet.

Feng Yan shrank his feet, the iron cable that buckled his feet was withdrawn, and the stone surface also rose back to its original place, and Lan Wei hurriedly used the things under his hands to mark a big cross in the place where Feng Yan had just stepped on. Indeed, once the mechanism is retracted, ordinary touches will no longer shoot small arrows.

This is how the location of the entrance was determined.
