The bottom of the swimming pool is laid with a non-slip floor, in the shape of a small square, the walls around the swimming pool are laid with the same color wall tiles as the bottom of the pool, it is still a small square, but it is more fine, and in these fine squares, there is a small square that is a little more convex than other squares, it is very subtle, if you don't look closely, you can't detect it at all, and this is the door switch of the underground room.

Lin Jinghan and Xu Shengrui stood at the bottom of the pool, Xu Shengrui saw the place pointed out by Lin Jinghan, a flash of surprise flashed in the evil peach blossom eyes, no wonder he searched for so long and didn't find where this real base is, such a subtle detail, if it wasn't for Lin Jinghan's point, Xu Shengrui would definitely ignore the mechanism at the bottom of the pool, mainly because this place is not within the scope of ordinary people's thinking.

"Rui, let's go in first, I sensed that the two of them have gone deep into the ground for almost three hundred meters, I really didn't expect that this real Yàn base would be built so deep underground, this Dongfang family really put a lot of effort into building it, so it seems that what they are trying to do is definitely not small!" Lin Jinghan's elemental perception has always been paying attention to the movements of Dongfang Mingzhu and Ling He, and at this time, even if Lin Jinghan and they open this mechanism, I believe they will not find out.

"Well, it's because the Dongfang family's actions have become bigger and bigger recently that I noticed them, this real yàn base wants to be built is definitely not an overnight thing, it seems that this Dongfang family has been plotting for a long time, Han, let's go, this time, we must pull out this real yàn base, and break their proud dependence!" Xu Shengrui also has a water-blue elemental enchantment on his body, which Lin Jinghan gave him.

"Good!" Lin Jinghan raised her hand and pressed it towards the small bulge.

The subtle sound of maneuvering sounded, and because it was covered by the pool water, it was almost impossible to hear it on the pool, which is why the builders of this place considered putting this gate under the water.

When the sound of maneuvering stopped, a hole about one meter high and about half a meter wide was revealed, and Lin Jinghan finally knew why this door could be opened so stress-free, and the water in the swimming pool was not affected in the slightest.

It turns out that inside this doorway, there is still water.

There is water on both sides, and the water in a sealed area inside this door hole is full, so the water in the pool will not flow towards the door hole, but the water in the door hole will rush towards the outside swimming pool, but even if the water in the outside pool increases, no one will pay attention, so this door is open under this pool, and no one will think of it, and it will never be noticed, unless the pool of the outside pool is dry.

Is there no water in the swimming pool of Xili Villa, which is just the top luxury club? That's simply not possible.

So, this is a top-notch mechanism, and the person who can design such a mechanism is definitely a genius!

Lin Jinghan and Xu Shengrui glanced at each other, with shock and abruptness in their eyes, but after this, the two of them became more cautious about this trip.

Someone who can design such a gate will definitely not prepare any precautions when designing the more important real yàn base underground!

Xu Shengrui stretched out his hand and held Lin Jinghan's right hand, and then bent down and entered the doorway, while Lin Jinghan followed.

When the two of them just entered, the door automatically closed back, the pool was clear, and there was little silence between the couples, and no one was there.

The pool inside the door is not large, rectangular in shape, no more than two meters long, this is just a transition, resisting the water of the pool outside, acting as a buffer, so that when the door is opened, there will be no big noise, attracting the attention of others.

In front of the pool is a staircase, not many, only a few steps, just stepping from the water to the ground.

As soon as she came out of the water, Lin Jinghan removed the barrier on the two of them, looking at the two-meter-high and one-meter-wide underground passage in front of her, Lin Jinghan twitched her nose slightly, and then said to Xu Shengrui: "There is no other odor in the air, and the air is very dry.

"Well, there should be more than this entrance here, and after we go in later, it is best to be able to catch all the people here, otherwise, once someone escapes, then it will be a surprise." Xu Shengrui's face was serious, just looking at this door, this tunnel construction, Xu Shengrui knew that what they had to face this time was definitely not simple.

"Well, let's be careful, Dongfang Mingzhu and Ling He have already stopped, three hundred meters underground." Lin Jinghan raised her head and told the latest information.

"Looks like we're on the ground, let's hurry over!"

"Let's go!"

There is a wall lamp every other meter in the passage, which illuminates the passage very brightly, as if it is daytime, if it is not that the passage is too small, giving people a feeling of depression, it will really give people a feeling of being on the ground.

Lin Jinghan and Xu Shengrui in order to pass faster, the two of them directly carried the light technique and quickly swept through the tunnel, their speed was not comparable to the two of Oriental Pearl and Ling He, in the narrow passage, the two of them were like a puff of light smoke, floating silently.

When the two of them went about 100 meters underground, Lin Jinghan suddenly grabbed Xu Shengrui, who was advancing, Xu Shengrui trusted Lin Jinghan wholeheartedly, and he didn't ask why for Lin Jinghan's movements, just stood in place and kept the original movements.

Lin Jinghan closed her eyes and carefully felt the elemental power here, compared to the tunnels in front of her. [,！ ], the power of the elements here is a little mottled, more complicated, almost all of the previous tunnels were filled with earth elements and gold elements, but here, the gold element actually has a tendency to overwhelm the earth element, that is to say, there must be a mechanism here, and it is an offensive mechanism.

Lin Jinghan searched carefully, but because the elements in this tunnel were too tightly mixed, Lin Jinghan couldn't find where the mechanism was for a while.

Suddenly, Lin Jinghan patted her forehead, how could she forget these little things, she couldn't tell them, but if she let those few little things tell them, it would definitely seem quite easy, and there were no other people in this tunnel, and the mottled aura in the air outside had not penetrated into this position of a hundred meters underground, so it was completely fine to let them out.

"Lanlan, Xiaotu, Huohuo, Qingqing, come out and help me!" Lin Jinghan whispered to her elemental elves in her heart.

When the words fell, the four elves appeared beside Lin Jinghan with their little wings, and circled around Lin Jinghan affectionately.

"Master, master, Xiaotu misses you so much!"

"Qingqing has seen the master."

"Lan Lan has seen the master."

"Humph!"

"Hehe, do you guys feel uncomfortable here? If you can't get used to it, why don't you go back to the contract space first?" Although Lin Jinghan felt that there should be no problem, Lin Jinghan was still a little worried.

"Hmm, it's such a rich earth element, haha, it's so comfortable, it's so comfortable, master, Xiaotu likes it here, I don't want to go back to the contract space!" Xiao Tu took two deep breaths, feeling very comfortable with the earth elements that were all around him.

"Don't worry, master, although there are not many wood elements here, the aura is still abundant, so there won't be any problems in a short time." Qingqing flapped her little wings around and then confirmed.

"Humph!" This time, this "hum" is not made by the same person as the previous body, the previous hum is definitely just a tsundere expression, and the current hum is to make the few elves present feel cold all over the body.

Woo-la-la!

After a few shakes, the four elemental elves lined up in a row, bowed slightly to Xu Shengrui, and said in unison: "I've seen the lord!"

Xu Shengrui's black color that sank like the bottom of the pot finally slowly faded under this "lord".

Lin Jinghan watched it funny from the sidelines, Xu Shengrui would be jealous of these elemental elves, is it really ・・・・・・ is that a few elemental elves were too excited and excited, and didn't notice that there was another person in this passage for a while?

However, seeing that Xu Shengrui was still in place and didn't dare to move in the slightest, Lin Jinghan also felt that she couldn't delay any longer, so she hurriedly ordered Xiaotu: "Xiaotu, can you help me see where the mechanism here is?"

With Xu Shengrui here, a few little guys didn't dare to be presumptuous, and when they heard Lin Jinghan's command, Xiaotu quietly stuck out his tongue, and then looked for it with a stern face.

Xiao Tu is an earth element spirit, he is completely bred by the earth element, he can control all the earth elements in the world, and he is the most sensitive to the power of the earth element, in this passage, Xiao Tu only took a minute to detect all the mechanisms clearly.

"Master, there is an iron plate in the ground, and the iron plate has spikes on it, and if you step on the mechanism, this floor will fall, and then people will fall on the spikes." Xiao Tu's little face with baby fat was full of heaviness, completely contrary to his image of a little brat.

The floor that Xiaotu said was the one in front of Xu Shengrui's feet, and when they heard what Xiaotu said, Lin Jinghan and Xu Shengrui couldn't help but take a breath of cold air.

Fortunately, Lin Jinghan's movements were fast and she grabbed Xu Shengrui, otherwise, the two would have fallen into the trap, although according to the skills of the two, the two of them could jump by strength, but there were all spikes underneath, and if they escaped with strength, one of the two of them would definitely be injured.

However, Xiaotu's words are not finished.

"Here, there's an arrow behind this wall, and here's its mechanism." Xiao Tu raised his finger and pointed to the floor tile on the left, against the wall, diagonally opposite the ground under Xu Shengrui's feet, "This is a trigger-type mechanism, as long as it touches it, the sharp arrows in that wall will shoot out instantly, and at this time, people are walking against the wall, and they will definitely be strung into a hornet's nest."

Lin Jinghan and Xu Shengrui's faces have not become very good, the human mind of this design is too vicious, and he understands people's thinking too well, under normal circumstances, in the unknown secret passage, people will definitely choose to walk against the wall, so that at least they can avoid the concern of killing on all sides, and their backs against the wall can also give people a sense of support and security, so that people can maintain a stable state of mind in the secret passage.

And the most important point, in the experience left by the predecessors, it is generally not dangerous to walk against the wall, and this is also regarded as a creed by many people, when in the passage, there is no absolute certainty, people are definitely groping forward against the wall, and Lin Jinghan and Xu Shengrui are bold from time to time, and the two will not directly sweep forward in the center!

Now that I think about it, if the two of them really leaned against the wall, maybe both of them would have been hit, which has to be said that the two of them were very lucky, and they actually hit the right one, dodging this wave of sharp arrow attacks, and avoiding the possibility of becoming a hornet's nest.

It's just that before Lin Jinghan and Xu Shengrui could breathe a sigh of relief, Xiaotu said a piece of news that made the faces of the two even more ugly.

"And inside this wall, there's some kind of gas that I can't sense, but it should be very corrosive, because I feel the dirt around it. [,！ Elemental exhaustion." Xiaotu pointed to the opposite wall and said again.

"And the trigger mechanism of this wall is this piece under the feet of the lord!" ――
