"Is this just the rumor...... Can the burial of bones lead directly to the tunnels of Canglan City?"

After being silent for a moment, it was Tang Shu who opened his mouth first.

"It's not clear, but it's very likely. After all...... If the tunnel is hidden in this swampy quagmire, it will indeed not be discovered under normal circumstances. It's no wonder that for so many years, although the rumors have been spread with noses and eyes, they have never been really found. ”

While Ye Ning spoke, he wanted to reach out and rub his chin.

It's just that as soon as my hand was raised, I remembered that I was now covered in mud, and the movement of rubbing my chin was too dirty, so I put it back down in embarrassment.

"Isn't it too troublesome? In the swamp quagmire you just dived into, there is a spirit guide device used to activate the mechanism, and through that spirit guide device, you can activate the mechanism of this swamp quagmire, so that the passage in front of you can be exposed...... In that case, why don't you just put that spirit guide device in this swamp quagmire, or don't you make a spirit guide device and mechanism, leaving only that passage?"

Tang Shu frowned and asked.

"Maybe it's for double insurance, if there is only one channel, it will be difficult to solve the problem of how not all the sludge in the swamp quagmire flows into the channel. With the addition of a spirit guide device, a corresponding secret door can be left in the passage, which can be raised or lowered as the spirit guide device is activated. ”

"Being in two different swamp quagmires would make this kind of hiding safer, and even if someone could find the spirit guide device, they wouldn't be able to find the true passage for a while. And if someone finds the passage by chance, it will naturally be of no use. ”

Ye Ning said guessingly.

"Speaking of which, I don't really understand, why did you find that spirit guide device? hidden in the swamp mire, unless you are sure that there must be something inside...... There's no way anyone wants to get in, right?"

Tang Qihu looked at Ye Ning suspiciously and asked.

"Well, accidents, accidents, I'm more sensitive to spiritual reactions, and the spiritual guide device exudes spiritual reactions, so you can naturally find out. So I'm curious about why there is a spiritual reaction in the swamp quagmire, so I want to find out. Now that I think about it, that spiritual reaction is probably some kind of limitation, and it has to exceed the strength of its spiritual reaction before it can turn ......."

Ye Ning said very vaguely.

Tang Qi's eyes were full of suspicion, but he didn't continue to ask.

After a brief discussion, the two decided not to explore the passage for the time being.

He waited at the edge of the swamp for a while, and found that after ten minutes, the sludge that had been drained had begun to seep out of the bottom of the swamp again, and soon filled the empty swamp mire.

Ye Ning frowned, and after saying hello to Tang Shu, he returned to the original swamp quagmire, retied the vines, and then entered the swamp quagmire again.

I found the spiritual power device well, and found that the disc that had been turned to the end didn't know when it would return to its original state.

After groaning, Ye Ning continued to turn the disc to the bottom, climbed out of the swamp quagmire, and went to the edge of the swamp quagmire over there with Tang Shu.

Sure enough, half an hour passed from the moment the disc was turned, and the previous scene continued.

If it was repeated a few times, Ye Ning and Tang Shu also determined that there was a time limit for this spirit guide device, and as soon as the time limit of half an hour was up, the spirit guide device would be restored to its original state, and this swamp quagmire that had been drained of sludge by the mechanism would also be filled again.

Confirming this, Ye Ning and Tang Shu didn't stay any longer, and turned around and headed back towards the tree house.

Because they came back relatively early, Lin Chuxia and Du Fei were still outside, so Ye Ning found a water source by himself and carefully cleaned himself up and down, inside and out.

But even so, the smell that went deep into the swamp quagmire still couldn't be completely cleared, which made Ye Ning quite depressed.

In the evening, Lin Chuxia and Du Fei finally returned to the treehouse from the other direction, and as soon as they returned, they expressed their curiosity about the strange smell emanating from Ye Ning's body.

The corners of Ye Ning's mouth twitched and explained briefly to the two of them, and then told the discovery and harvest of Bai Bai and Tang Chop without any concealment.

Du Fei and Lin Chuxia obviously showed very interested expressions, and after a brief discussion, the four of them decided to temporarily stop hunting with each other.

After a night's rest, he returned to the temporary camp early the next morning, and then exchanged his points for a lot of clothing and daily necessities in the temporary camp, and then went to the swamp again.

Holding back the stench, Ye Ning activated the spirit guide device, and Du Fei and Lin Chuxia witnessed a small swamp quagmire being emptied abruptly, which was really an eye-opener.

The four of them jumped into the emptied swamp quagmire and entered the passage.

In the dark passage, I turned on the exchange of the lighting guide, and after walking four or five meters forward, I found that the walls of the passage suddenly became as clean as ever, and there was no trace of sludge staining.

Ye Ning couldn't help but stop, and after waiting for about ten minutes, there was a mechanical sound on the passage wall, and as the sludge seeped out from the bottom again, a heavy gate slowly fell from the top of the passage wall.

In a few moments, this passage was closed by the gate without leaving any gaps!

With the lighting spirit guide, of course, the passage was transparent, and the four of them did not delay any longer, and walked along the passage, that is, a distance of several hundred meters, and saw a groundwater pool that seemed to be formed naturally.

And at the bottom of this pool, there is also a feedback of 1,400 combat power points!

It should look like the spiritual power device in the swampy quagmire outside, one inside and one outside, can control the gate of the passage and the corresponding mechanism.

"I know that there must be a prepared place to wash my body, otherwise, if I come in once, I will be stained with sludge, who will suffer it?"

Ye Ning said with a smile, and then took off his clothes and pants full of mud, jumped into the waterhole and washed them.

The pool water was cold to the bone, which lifted Ye Ning's spirits, and after cleaning it quickly, he found that his body was not only clean, but also no longer had any peculiar smell, but there was a light fragrance floating on the surface of his body.

Changing into a new set of clothes and trousers, the four of them continued on their way.

Du Fei silently calculated the distance in his heart, and after about ten kilometers, the eyes of the four of them suddenly opened up!

The passage, which was originally only two meters high and about one meter wide, suddenly became a secret room with a size of more than 100 square meters!

The height of this secret room is almost three meters, and directly opposite the secret room, there is still the same passage, but on the stone walls on both sides, there are two doors each!
