You must know that these vortices are not just decorations. When they expand to a certain size, they will form intricate undercurrent networks.
At that time, everything in it will be locked by the chaotic undercurrent of the water, and then be swept into the downward vortex.
Even if one is lucky enough to escape death, the consequences of losing one's car in such an endless ocean can be imagined.
It is for this reason that Chen Ziyan chose to escape as soon as he realized what was going on.
Thanks to his timely reaction, the Trident was already some distance away by the time he clearly felt the drag force in the water.
After initially escaping from the danger zone, Chen Ziyan relaxed his tension and suddenly found that at some point, the dark sky lit up.
A bright moon hung in the originally dark night sky, and its bright moonlight shone on the sea, illuminating their vision.
Through the moonlight, Chen Ziyan saw that the sea behind him was now covered with whirlpools of various sizes. It looked like there were at least dozens of them.
And as these vortices expanded, loud sounds like loud bells gradually came from the bottom of the sea, and the 'rumbling' sounds shook the sea surface with ripples.
Even the boat that took them on was shaking along with it.
From this, it is not difficult to guess what the area where the vortex is now looks like.
"Master Chen, Lao Hu, is this the legendary sea cave?"
After a brief silence, Wang Kaixuan was impatient and curious, and couldn't help but ask.
Although he had never seen the scene before him, he had heard of similar situations in stories.
"Probably." Hu Bayi replied somewhat uncertainly.
However, he was basically certain in his heart that what he encountered was a 'sea cave'.
As a natural disaster at sea that is comparable to the "Shangshui Dragon", the characteristics of "Sea Cave" are also very obvious, so after seeing the specific situation clearly, Hu Bayi had the answer in his heart.
Maybe it was to give himself confidence, so after Hu Bayi finished speaking, he subconsciously looked at Chen Ziyan.
Judging from his intention, he wanted to ask Chen Ziyan for his opinion again.
However, he found that Chen Ziyan was staring at a certain position in a daze. This made him curious and he looked over.
It's just that Hu Bayi didn't see anything. Apart from the gradually expanding vortex, there was nothing else in his sight.
Feeling Hu Bayi's probing gaze next to him, Chen Zi extended his finger to point to one of the vortices and asked: "Old Hu, look at the position of this vortex, is it directly above the underwater space we just entered?"
Um?
Hu Bayi was stunned by his question, but he didn't think much about it and quickly looked in the direction pointed by Chen Ziyan.
After making some mental calculations, he was surprised to find that what Chen Ziyan said was indeed correct.
Even if there is a deviation, the location of this vortex is still above the underwater space that contains the ruins of the ancient city.
After confirming this, he also understood why Chen Ziyan was stunned.
"Mr. Chen, is this not a coincidence?" After a moment of silence, Hu Bayi asked with a frown.
Chen Ziyan shook his head: "Definitely not."
Even though the connection was still unclear, one thing he knew very well was that the appearance of the vortex couldn't be a coincidence.
He had also heard rumors about sea caves, and with his understanding of the original plot, Chen Ziyan knew very well that the appearance of these vortexes was not random, and there must be some kind of pattern within them.
Then Chen Ziyan raised his head and looked at the sky: "I think not only the sea surface and the bottom of the sea, but also the sudden appearance of the moon has something to do with it."
He thought of the invisible barrier encountered at the bottom of the underwater space.
There are only a few principles that can form a barrier, and based on what he knows, the most likely thing is that there is an upwelling of air currents on the seabed.
If the hot air current at the bottom of the sea breaks out of the sea water, it can completely disperse the clouds that block the moonlight.
Hu Bayi heard the implication of his words and felt a little unbelievable: "No way?"
Although this speculation is indeed possible, it is not easy to realize.
Putting aside everything else, just being able to break through the barrier of sea water is a difficult problem.
"Of course it won't happen normally, but if all the air currents accumulated on the bottom of the sea are vented, it is still possible to do this." Chen Ziyan became more and more sure of his conjecture at this time.
He didn't know what conditions were needed for the sea cave to appear, but it was definitely not simple when he thought about it, and there was more than one whirlpool appearing in front of him now.
Not to mention that this is a coral spiral. This is a place that cannot be viewed with common sense. It is not surprising that anything happens.
After hearing what Chen Ziyan said, Hu Bayi also began to consider the possibility of this speculation.
Although he felt it was impossible, he had to admit that what Chen Ziyan said did make sense.
This made him subconsciously observe the vortices, and it didn't matter. He quickly discovered the problem.
"Master Chen, there is something wrong with the distribution of these vortices!"
"What's the problem?"
"It seems to be some kind of hexagram?" Hu Bayi said with some uncertainty.
Because he usually studies this area, he can notice something is wrong.
But their current perspective is limited and they are unable to make a more accurate judgment, so he just feels familiar and cannot be completely sure.
"Hexagram? Can you confirm it?" Chen Ziyan immediately became energetic after hearing Hu Bayi's words.
If the distribution of the vortex really conforms to a certain hexagram, then the meaning it represents can be explained.
"Wait a minute, let me change places and take a look." Hu Bayi did not give an answer immediately, but planned to change places and take a closer look.
