And what made Zheng Zheng feel strange was on the ground paved with wood.

"This Ground ......"

Zheng Zheng squatted down, looked at the exposed wood-colored ground through the light at the entrance of the passage, and frowned secretly: "...... Isn't it too clean?"

The ground is actually not clean, there are a lot of shoe prints on the square wood paved ground, but those shoe prints seem to have been around for a while, and they should have been left on the ground by the workers when the ground was laid.

Zheng Zheng's cleanliness means something else.

Frowning and thinking about it, he took a few more steps into the passage, and looked carefully at the ground he passed, Zheng Zheng nodded and retreated from the passage.

Then, he went to the entrances of the passage on the left and right, and carefully looked at the ground within five meters of the passage.

Everyone in the hall was looking at the pen wash on the table, and no one paid attention to him. Even if they saw his actions, others would not think it was strange, but they would only think that this young man who was wandering around here instead of concentrating on appraising antiques was really a waste of time.

After looking at the ground of about five meters in the three passages, Zheng Zheng's brows furrowed even tighter.

Zheng Zheng remembered very well that although the Erhei who sent the antiques in only had a pair of boxer briefs on his body, he was still wearing shoes on his feet. One thing Zheng Zheng remembers more clearly is that the tunnel that slopes down is not paved with wooden planks, but with earthen steps.

Although the weather is cold now, and most of the soil on the surface is frozen soil, it is not reasonable to say that there is not a single trace of soil on the soles of these shoes.

If Erhei really ran quite fast as the young man said before, then he would definitely use a lot of force when he stepped on the ground, and the friction between the soles of his shoes and the ground would also be very strong.

In that case, the soil on the soles of his shoes would have to be left on the ground anyway, forming a shoe print, right? The ground was paved with unpolished square wood, which was not smooth at all, it was quite rough, and the ground was whitish. It's hard to run quickly on this kind of ground, and the soles of your shoes rub against the rough ground without leaving a shoe print.

And the current situation is that on the ground five meters of the entrance to the three passages connected by this hall, except for some shoe prints that you can tell at a glance that they have left for a while, there is not a single fresh shoe print at all.

Zheng Zheng looked carefully and clearly enough to confirm that there were no omissions or errors in judgment. Judging whether the time left by a shoe print is near or far, Zheng Zheng, who was a bully when he was in school, kicked on other people's desks, is quite a speaker.

To explain this situation, there are only two possibilities: first, that Erhei is a master of light skills, who can cross the river without a trace of snow and a reed, and he is completely in the posture of volleying in the void and wandering around in this "ancient tomb".

The second possibility is that Erhei has never entered the three passages connected to the hall at all, and he has only been to the hall at most.

This is still because everyone walked around the hall and said that the ground was full of footprints, and it was impossible to verify whether there were footprints left by Erhei before everyone entered. If Zheng Zheng could have thought of this before entering the hall and came to the front of the line to observe, he would have been able to determine whether Erhei had entered the hall or not.

"Is that antique hidden in the hall? ...... possibility?"

Zheng Zheng looked at the dirt walls around him that had only been lightly repaired, shook his head, and said secretly: "This possibility is too small, almost negligible." It's too easy for people to find out if you want to make a dark grid on this kind of dirt wall, but if it's a brick wall, it's really possible......"

Thinking of the "brick wall", Zheng Zheng's heart moved, he no longer cared about the situation in the hall, turned around and walked towards the passage that came in.

If we talk about brick walls, the walls reinforced with square wood in the passage are, from a certain point of view, just like brick walls.

Walking into the passage, Zheng Zheng did not rush to knock on the square logs on both sides of the wall one by one, but carefully observed.

But wherever there is a dark grid, although it is covered up as much as possible, it will still show some differences from the surrounding environment. Either it's a little more worn, or it's dirtier, or it's something that's different from other hidden markings. In any case, there will be some differences in details, and no matter how much you try to hide it, you can't completely hide the past.

However, Zheng Zheng's search was in vain, except for some differences in the texture, the square wood on the walls on both sides was no different, and there was no square wood that was more worn than other square wood or dirtier because of more contact.

There was no trace to be seen with the naked eye, and Zheng Zheng did not give up and tapped the square wooden walls on both sides with his fingers. The result is still the same, the feel from the square wood shows that these square wood are solid after it, and there is no such thing as a hollow dark grid.

Going back and forth in this dark passage, Zheng Zheng spent nearly half an hour. It was in vain to find it for half an hour, and Zheng Zheng was really a little discouraged.

Looking up at the square wood above his head and the floor under his feet, Zheng Zheng began to wonder if the antique could be hidden in these two locations. He also knows that it is really unreliable to open the dark grid in these two positions, and there is a risk of breaking the antique by opening the dark grid on the top, and opening the dark grid on the floor under his feet also has the risk of being trampled on the dark grid, which is a very unreliable position. However, Zheng Zheng really has no clue now, so he can only make conjectures in such an unreliable position.

After pondering vigorously, Zheng Zheng subconsciously looked at the section leading to the tunnel. Under this look, Zheng Zheng's heart moved.

The section of the passage connecting the tunnel is about ten meters long, and I don't know why there is no light. However, the lights in front of you are quite bright in this dark section, so although you can't see under your feet clearly when walking this way, there are lights in front of you to guide the way, so it is not a big problem.

And in this passage, there is only this dark section of the road that has not been checked by observation or percussion.

"If that compartment is in that position, it's a good position. ”

When this thought came to mind, Zheng Zheng began to ponder in his heart: "There is no light in that position, it is pitch black, so even if there are many footprints left on the floor of that passage, we will not care when we first enter because we can't see our feet because there is no light." By the time we walked through that section, the footprints had already been mixed together, and naturally we couldn't see if there was any problem. ”

"And opening a dark grid in such a position where there is no lighting basically cuts off the possibility of the player looking at the problem from the outside. The only possible way to do this is to try to find the location of the dark grid by tapping on the wall. But after entering the passage, everyone is heading inside, and no one wants to be left behind, and who will be suspicious because that part of the road is dark, and leave it to check?"

"Once the player is in the hall, they should check the antiques in the hall, then the antiques in the rooms on either side of the hall, or look for other antiques in the rooms connected to the back passage of the hall. When everyone is looking for real antiques, it naturally creates a tense atmosphere, and who has the time to be distracted at this time?"

Thinking about this clearly, Zheng Zheng couldn't help but praise softly. Fortunately, Zheng Zheng was alone in the passage, and he was not afraid of being listened to by others: "Wonderful...... Hey, it's just pulling all the players by the nose. Although he did not give any instructions, he took advantage of the eagerness of the players who took out 300,000 yuan to win, and the tension caused by the secret competition between them, so that these players obediently followed his plan, and wasted their efforts in places where it was impossible to find antiques. And the more they can't find it, the more nervous and anxious they will become, and the less anyone will think about things like the secret grid......"

Zheng Zheng gave his own evaluation: "The one who designed this step is really a fucking talent......"

It's not enough to figure this out, the most important thing is to find the location of the antique. Only by finding that secret grid, and that there is indeed an antique hidden in that dark grid, can Zheng Zheng's conjecture be verified.

After finding the light bulb installed on the wall in the dark but did not light up, Zheng Zheng further proved his idea: the light bulb installed on the wall by Zheng Zheng found did not burn out at all. In other words, the bulb can be used, but for some reason the bulb is deliberately not allowed to illuminate.

As for why you don't let this working bulb illuminate, it's obvious why.

groping for the wooden squares on the wall in the dark, Zheng Zheng knocked them one by one, and finally when he knocked on a square wood near the bottom of the wall, the feeling that had been going on finally changed.

The square log echoed muffled after the tapping, and it was clear that there was a place behind the square that was empty.

Flipping through his body casually, Zheng Zheng took off the key chain, groped for a flat key, and reluctantly stuffed the toothy side of the key into the gap between the square wood and the other square wood.

Shook the key left and right, so that the key fell into it more, Zheng Zheng stretched out his palm and slapped it on the end of the key, and his palm hurt for a while, but the key also fell into most of it.

Shaking the key steadily for a while, the square piece of wood was partially snapped out. Zheng Zheng grabbed the edge of the exposed square wood with his fingers, and after a struggle with his hand, he only heard a slight "click" sound, and then pulled the square wood out of the wall.

Holding Fang Mu, Zheng Zheng held his breath and listened attentively to the nearby movements. After all, this place is close to the ground, and it would not be good if it was heard by the people on the ground.
