He hadn't realized it just now, but now when he looked back and thought about it, Chen Ziyan suddenly realized that it seemed that his exploration of the grotto was not comprehensive.
For example... I subconsciously thought that the pools inside and outside the grotto were integrated, and I didn't go down to take a look in person.
Although from the surface, the location of the grotto is slightly higher than the pool, it is reasonable to assume that it is above the pool.
But this is just his guess after all and has not been verified. Maybe the actual situation is not the case.
After this idea appeared, Chen Ziyan could no longer control his heart. After asking the two guys to stay here and wait for him, he used the rope to swing to the grotto again.
Without clarifying the doubts in his heart, it would be difficult for him to feel at ease.
Chen Ziyan, who came back to the grotto, did not rush into the water, but took out his weapon, intending to use it to explore the way first.
After all, the small pool in the grotto also cuts off the light, so going down rashly is not a good choice.
As the long stick slowly penetrated into the water, Chen Ziyan's expression gradually became strange.
Because something he hadn't expected happened.
First of all, the pool was much shallower than he thought. The long stick had already touched the bottom before it reached one meter.
Next is the bottom of the small pool, which is a bit unreasonable.
Based on the touch feedback from the other end of the long stick, Chen Ziyan immediately judged that the blockage below was not a hard object.
With a little more force, he actually felt elasticity, as if he had poked some rubber product.
Chen Ziyan then changed his position several times, but the results were the same, and no other problems occurred.
This situation reminded him of the hollow where the coral tree was.
To be more precise, it is the invisible barrier between the hollow and the sea water above. Although the bottom of this small pool is more flexible, the overall feeling between the two is similar.
Thinking like this, the muscles of Chen Ziyan's arm holding the long stick swelled, and he stabbed down with all his strength.
He wanted to try to see if the bottom of this small pool could not be broken through.
The effect was not very satisfactory at first, because as Chen Ziyan applied more force, the resistance from below also increased.
However, he was not discouraged. This situation had been expected. After a stalemate for a while, Chen Ziyan used his other hand.
Because of the strength of the resistance coming back from below, he felt that if he applied more force, he should be able to break through this barrier.
Facts have proved that Chen Ziyan's feeling was not wrong. When he exerted force with both hands at the same time, the barrier below did not last long and was successfully broken through by the long stick pressed against it.
The moment the long stick passed through the barrier, Chen Ziyan felt a sudden lightness in his hand. Not only did the long stick go in, but he almost fell into the water while standing on the shore.
Before Chen Ziyan could stand still, a strange force came from below, pushing the long stick back and straightening his leaning body.
This sudden change made Chen Ziyan stunned for a moment, but he quickly came to his senses and knew that the power under the barrier was causing trouble.
At the same time, Chen Ziyan stabilized his body again, and stabbed hard again with both arms holding the long stick.
Just one try was not enough. He had to try several more times before he could be completely sure.
Two minutes later, Chen Ziyan put away his long stick and began to check his equipment.
After several attempts back and forth, he was basically certain that the situation under the small pool was no different from the top of the hollow. The only difference was the intensity of the invisible force inside.
After getting this answer, he planned to go into the water to check it out for himself.
Because when he just changed positions, he also discovered another problem, that is, the small pool in front of him seemed to be not only shallow, but also not very large.
After he was sure it was correct, Chen Ziyan went into the water.
Going into the water...well, I use this word reluctantly, because the depth of the pool cannot accommodate him at all, and the height of the water does not even reach his waist.
However, Chen Ziyan didn't pay much attention to this, because after entering the water, his attention was immediately attracted by the touch under his feet.
Very different from the hard touch of the barrier above the hollow, the bottom of the small pool gave him the feeling of stepping on a rubber carpet. He could even feel the feeling of the soles of his shoes sinking in.
This was in line with his expectations, because when he just used the long stick to test, the feedback feedback was like this.
The only difference is that it was not as clear back then as it is now.
Slowly squatting down, Chen Ziyan did not directly put his head down, but first pressed his hand on the bottom of the pool.
After retracting his hand, he was completely sure that the toughness of this partition was far worse than that of the hole.
Then he moved his position, groped around the edge of the pool, and quickly came to the answer. The area of the small pool was indeed not large, and the edge of the pool was opposite to the bottom of the pool.
Chen Ziyan originally thought that this small pool was integrated with the pool outside, but now he discovered that things were not what he thought. This was actually a separate space.
After he put his head into the water in a rather strange posture, he quickly saw the entire small pool clearly.
There is nothing but water in this small pool. Below it is a dark barrier, and around it is a circle of stone structures.
After confirming that there are no gaps in the surrounding stone structure, Chen Ziyan can basically confirm that the bottom is also formed in one piece, just like the hollow stone pillars in the pool outside.
Thinking of the hollow stone pillars, Chen Ziyan suddenly realized that this pool seemed to be made of the same material as the stone pillars.
No wonder he always felt that the surrounding stone structures gave him a sense of familiarity.
After realizing this, Chen Ziyan also realized that maybe this was also a hollow stone pillar.
It was just because of the grotto above that he mistakenly thought it was a simple pool.
After coming out of the small pool, Chen Ziyan glanced around for a few times and suddenly thought of a possibility.
Perhaps the water in this small pool did not originally exist.
As we all know, when something is put into a container filled with water, the water inside will overflow.
Judging from the fact that the grotto is only slightly higher than the pool outside, when the stone pillars and the stone platform fell down, the people in the pool would definitely enter the grotto.
The small pool inside is a separate space, so you can imagine where the water in it comes from.
Regarding this possibility, Chen Ziyan also has another piece of evidence, that is, when he went into the water, he discovered that the floor of the grotto was not level, but had a slight slope.
If water does get inside, it will not flow back outside until the small pool is filled.
