Illuminated by the light of the enchanted pearl, the three of them quickly dived into the depths of the cavern.

The submarine cave that was originally a beast's den is actually very deep, with many forks in the road, and it has a bit of a taste of extending in all directions. Bai Xiaowen and the others always kept moving in one direction, and soon came to the deepest part of a cave.

"Incredible...... The height from the entrance of the cave should be more than 100 meters, right?" Li Shuyi said, "What animal would dig the cave so deep?"

Aswan said, "As I said before, there are a lot of ferocious beasts in this area, maybe it's a giant python, maybe it's a wurm, I can't say. ”

It's a rock face, but there's a triangular fissure. If you get closer, you can feel the speed of the sea rushing into the chasm.

"This crack should be caused by the earthquake, and it is connected to another cave space...... Bai Xiaowen looked at it, "enough for us to pass through in batches." ”

"I'll come first. Aswan said in a deep voice, "I don't know what kind of danger there is on the other side. ”

"It's fine. Bai Xiaowen didn't force it, as a high-level spiritual realm leader, Eswan's health value exceeded 1,000, and it was the most suitable to be the first pathfinder......

Eswan was in front, Li Shuyi was in the center, and Bai Xiaowen was behind, and the three of them were like three big fish, swimming along the triangular crack.

A few meters away, there was a slight feeling of weightlessness, and Bai Xiaowen felt that he was falling down the water. The sound of rushing water rang in his ears.

Puff, puff......

The sound of dumplings sounded continuously, and Bai Xiaowen and the three of them fell into a deep pool one after another, and then surfaced.

The three of them wiped a handful of water droplets in unison and looked up.

Eswan and Li Shuyi's faces showed surprise.

Here, it is a fairly large underground space, with irregular cracks on the ground and side walls, and collapsed stalactites everywhere, obscuring the view.

On the high wall behind the three of them, triangular fissures connected to the outside world, and the sea water rolled down, forming a waterfall.

Every second, a large amount of sea water washes into the deep pool, but the water level does not rise. It is precisely because of the buffer of this pool that a space without seawater has been created on the bottom of the sea.

This principle is also simple, as if you quickly press an upside-down bowl into the bottom of a cistern, and the air in the bowl will naturally not escape, creating a bowl-shaped air zone at the bottom of the cistern.

"Phew, looks like we've arrived. ”

Bai Xiaowen walked out of the waterhole, took out a photo crystal, injected a trace of spiritual power to activate it, and looked around at the same time. Occasionally, yellowish crystals can be seen on the ground, similar to those on the surface of the spiked shark.

Bai Xiaowen summoned the butcher again and ordered it to eat the crystals. Sure enough, he once again got the news of "devouring special minerals, armor and magic resistance", but this time the amount of devouring was less, only adding 6 armor and magic resistance.

Bai Xiaowen also got a hint on whether to cover the original effect, and of course he chose no. The reason why the butcher was allowed to nibble on this little bit of crystals was just to support his suspicions.

"What the hell is this place?" Eswan's green eyes were full of incredulity.

"According to the ancient books I consulted in the Wisdom Tree House, this place should be called ...... Leyline corridor. ”

It is quite rewarding to do local science popularization for spiritual figures, Bai Xiaowen's face showed a smile that matched the temperament of a prophet, and continued: "Our continent does not exist on the sea in the form of floating, but in the form of pillars. ”

"Pillars?"

"Yes, you can divide the Kuroshio Continent into several plates. The pillars of the leylines support these continental plates. Each pillar corresponds to a very empty underground space, which is called the leyline corridor. ”

Bai Xiaowen picked up a small pale yellow crystal: "Do you see this crystal? This is the leyline pillar...... fragments. ”

"Fragments?!" Eswan looked up suddenly, "You mean the leyline pillars here are ......"

"It's very quick to accept......" Bai Xiaowen was a little surprised, he thought that it would take a lot of words to make Aswan accept this fantastic fact.

After all, Bai Xiaowen, who was in the Wisdom Tree House at the beginning, also combined the picture of the prophecy slate with ancient books to determine this conclusion. And when the conclusion was just reached, Bai Xiaowen still doubted himself for a while...... And then he offered to come here to test his idea.

Li Shuyi followed and said: "Look at the mess here, it's like a world war, the leyline pillars must be broken." ”

Eswan muttered, "Could it be ...... The leyline pillars shattered, causing the leyline corridor to collapse, and then ...... There was an earthquake in the Amusa Forest?"

"That's right. Originally, it was a large leyline corridor, but the earthquake collapsed and the fracture and fall of large stalactites, dividing the underground space into many small areas...... Our current location is definitely the edge of the leyline corridor, and we have to go to the central area. Bai Xiaowen sighed and said.

"Go to the central area...... What are you doing?" Ace couldn't think about it for a while.

Bai Xiaowen tilted his head and glanced at him: "Of course, I found the original site of the broken leyline pillar." Do you think that just by what you have seen so far, you will be able to make the countries of the mainland believe me? In the central area, there must be more discoveries. ”

Seeing that Aswan was silent, Bai Xiaowen went straight forward, and at the same time opened the spirit scan, looking for gaps between the stalactite obstacles that could be passed.

"Master Aswan, hurry up and keep up. Xiaowen can never go wrong. Li Shuyi's reminder made Aswan come back to his senses and hurriedly followed.

Drilling through small, imperceptible crevices, the trio drew closer and closer to the core of the collapsed leyline corridor.

During this time, they also encountered some distorted beasts infected by the energy of the leylines, and more often than not, corpses. The living beasts have become manic and abnormal, and when they see other creatures of different races, they will attack as soon as they see them.

Bai Xiaowen used the reason of "asking Aswan to dial Charlotte's swordsmanship" as a reason, so that Aswan, a swordsmanship master, did not need to make a move, and Li Shuyi was the main output force. When encountering more than two monsters, Bai Xiaowen's summoned creatures will be on top of it, creating a one-on-one space for Li Shuyi to concentrate on learning swordsmanship skills.

Eswan did not doubt him, and patiently taught Li Shuyi swordsmanship skills, the most important of which was the sword singing skills.

However, Aswan also made it very clear to Li Shuyi that she could not learn the real elven sword art, which involved racial characteristics.
