The current situation is also relatively clear to Wu Yi and the others, and if they don't want to swim back into the water now, they can only walk along this passage.

There is a large amount of gravel on the ground of this passage, and there are some traces of artificial excavation on the surrounding cave walls, indicating that this is deliberately dug out, and the tomb owner spent so much effort to dig such a passage under the tomb, there must be his intention, and the possibility of trapping people is not too great, if you just want to trap people, there is no need to make it so troublesome.

Therefore, Wu Yi felt that the criss-crossing passages under the tomb were still very likely to be the underground drainage system of this ancient tomb.

Perhaps the location of this ancient tomb was located in the past, there were many underground rivers nearby, and the water level rose greatly, and the owner of the tomb was worried that one day his tomb would be flooded, so he specially built such a huge drainage system under the tomb.

Of course, this is just speculation, whether it is a drainage system or some other trap with ulterior motives, Wu Yi can't judge at the moment, so he can only take one step at a time.

After discussing a few words with Wu Dajiang, he had no objections, and the two began to walk forward along the passage.

The passage was extremely humid, and the further you went, the narrower the passage became, causing the water vapor to evaporate, and a layer of dark green mosses formed on the walls of the passage, and the gravel on the ground was also full of this kind of thing, which was not only slippery when stepped on, but also made a sound similar to chewing seaweed.

Fortunately, after the passage was narrow to a certain extent, it did not change, and the two of them did not feel crowded when they walked side by side, and after walking for about two minutes, after turning a few corners along the passage, they found something like a bogu frame blocking the way at a corner.

When I got closer and looked closely, I found that this was an iron shelf for placing tools, rusty, and a large number of tools for mining passages were placed on the shelf, but they were all useless, and the handles were made of wood, which had long been corroded into rotten wood by the humid air here, like mud pinching, and shattered when touched.

However, after Wu Yi took a closer look, he looked a little overjoyed, and said,

"Great, along this passage ten ** can go out, you see that the handles of these tools are facing the direction in front of us, which shows that those workers who mined this passage back then, after the completion of the tools to the shelf, they will directly turn around and go out The possibility is very high, if they left that year, they swam out by waterway, and the handle of the tool should be facing us!"

Wu Dajiang was a little confused when he heard this, and subconsciously said "ah" to express his incomprehension.

Wu Yi was in a much more relaxed mood at this time, so he explained to him,

"There's nothing hard to understand, you see this shelf blocking this passage, the first thing you can be sure of is that those workers must have been either on our side or on the other side of the shelf before they left, right?

If you look at the direction of the handles of these tools, they are all facing the front, which means that they must have been on the other side at that time, and naturally they went out directly along the passage. ”

After Wu Yi finished speaking, Wu Dajiang's expression was still sluggish, Wu Yi said that it was really difficult to talk to this person, there was no tacit understanding at all, if it was a fat man or a blind man here, he would definitely understand what he meant.

He took a small shovel with a fairly strong handle from the shelf in front of him and handed it to Wu Dajiang, saying,

"You put this thing on it, and you'll know what I mean."

Wu Dajiang did so, and after putting it down, he looked at the direction of the handles that were diametrically opposite to the original tool handles on the shelf, and then immediately patted his head and woke up.

"I see, when people put things in their hands, they always hold the handle, so the direction of the handle is usually facing their side!"

Wu Dajiang said happily, and then a little ashamed, "Master Wu, don't be surprised, I haven't encountered this kind of thing before, and I may not be able to keep up with your train of thought all of a sudden......"

Wu Yi waved his hand, and he didn't bother with this, some common-sense details are sometimes easy to make mistakes, just like layer window paper, confused to not be stabbed by others, and he can't figure it out if he wants to break his head.

Then Wu Yi said,

"Quick, take a hand, move this shelf, since those workers can get out of here, we can definitely too, unless there is a dead end ahead, and those workers are trapped in front.

But if that were the case, they would have turned back and left by the waterway, and the iron shelves and the tools on them would not have been placed here safe and tidy, and the trapped people would not be so peaceful. ”

Wu Dajiang nodded, and then the two of them worked together to push the iron shelf in front of them, the bottom of the iron shelf was very wide, as wide as two large wardrobes, and it was like it had taken root under it after being placed here for a long time, and the two of them didn't push it at once.

Wu Yi went out at this time, and when he saw that he couldn't push it, he didn't immediately have so much patience, so he let Wu Dajiang retreat one after another, and he took out a god-level Luoyang shovel and aimed it at a wrapping edge on the top of the iron shelf in front of him.

The explosive power of the god-level Luoyang shovel is still very strong, and it can instantly make a hole in the ground, you can imagine its power, at this time, under a collision, the edging iron sheet was suddenly poked open a big hole, and the entire iron frame also leaned back, and then made a loud noise, and the whole fell to the ground, and the tools on the shelf were even sparsely scattered!

This loud bang echoed in the empty passage for more than ten seconds before it completely disappeared, and it was like setting off a small bomb, smashing into a cloud of smoke and dust.

Wu Yi and the two choked and coughed a few times, and their ears were also a little buzzing, but at this time, no one was in the mood to care about this, and when they saw that the iron frame was overturned, they immediately set off and stepped over from it, and walked all the way forward.

This time, he walked on for less than a minute, and he came to the end of the passage, and at the end of it was a stone door that opened in the wall, about a meter and a half above the ground, and there was a pile of rotten wood on the ground below the stone door.

This pile of rotten wood must have been a wooden ladder built here to climb the stone gate, because it took too long to rot like this, Wu Yi didn't care about this, they could go up without a wooden ladder.

Thinking of this, he walked over and raised his hand to push the bottom of the stone door, but after pushing hard, the stone door opened a gap of a few centimeters backwards, and was bounced back again, as if someone was trying to prevent the door from opening behind the door!
