After all the monster corpses were disposed of, everyone began to do nothing, only then did they find the changes in the surrounding environment, and then, these people's hearts began to be a little afraid, these blood-red lights, it looks too depressing, depressed and even want to go crazy, some people want to enter the cave, but if there is only one person, they don't have the guts, after all, the hole is also terrifying, although they also feel scared here, but after all, there are many people.

Ye Zhan and the others crawled along the cave wall for I don't know how long, on this side of the cave, I don't know how many caves were found, these caves are not big, they can be easily identified, these caves should be the shelter of those monsters who rushed out of the cave, otherwise these monsters would not have rushed from the bottom of the cave to the top of the cave in such a short time.

You know, now they have been crawling along the cave wall for almost an hour, plus the distance they fell from before, they have continuously dropped tens of thousands of meters, even with Ye Zhan's extreme speed, it will take more than ten seconds to be able to break out of such a long distance, and these have to be built on the basis of flat ground, if it is a pit like this, this time may be extended dozens of times.

Moreover, as they kept descending, the air in the cave became more and more scarce, fortunately, this cave was very huge, so there was no shortage of oxygen in it, and the strength had reached the level of Ye Zhan and others, and they could already hold their breath for a very long time, even if they didn't breathe for a few hours in a row, there was no problem.

Fortunately, they finally came to the bottom of the cave, to be precise, the wall of the cave was gone, and the space below suddenly became very large, far exceeding the size of the cave, and less than a hundred meters below them was the bottom of the cave.

Immediately afterwards, the five people let go of their grip on the cave wall and jumped off the cave wall, but when everyone's feet touched the ground, they found that the ground was very soft, only a little better than the swamp pool, but the five did not sink into it.

"Wow~~"

Just as the five of them fell to the bottom of the cave, a tidal sound came from all around, as if everyone was in the water at this time, but when they looked around, it was pitch black, and they didn't see any water.

Similar to the previous speculation, at this time, on the ground around everyone, there were many corpses of Hell Emissary, these monsters had been smashed to pulp, apparently to death.

You know, I don't know how deep the depth of this cave is, and the speed of descent is increasing all the time, when the speed reaches a certain level, no matter how strong the strength is, it will be thrown to death, even if the ground at the bottom of the cave is soft, it will not be spared, even if it is water, if it falls at such a high height, it will be finished.

This is also the reason why Ye Zhan chose to climb down from the cave wall before, otherwise there would be Ye Zhan and others among these corpses at the bottom of the cave.

"Roar... Roar..."

Suddenly, there was a roar of monsters around, and then, countless monsters rushed out from the left position of the five people, most of these monsters were hell messengers who rushed out of the bottom of the cave before, but there were also other monsters, ghost tigers with grimace and tiger bodies, night walkers with black carapaces, etc., there were probably thousands of them.

After these monsters saw Ye Zhan and the others, their faces were full of excitement and they rushed towards Ye Zhan and the others, as if they had seen the most sumptuous food in the world.

However, after Ye Zhan and the others saw these monsters, they didn't find any panic on their faces, because the strength of these monsters was not too high, and the highest level was only level 50, which was a notch worse than the strength of those hell messengers who rushed out of the cave.

Ten minutes later, all these monsters died at the hands of five people, and none of them rushed out of the darkness on the left, which was very different from the terrifying existence in the depths of the cave that everyone imagined.

After that, Ye Zhan had the opportunity to observe the situation around them, above their heads, there was a huge hole, and around the entrance of the cave, it was like a stalactite-like top, with many upside-down stone pillars growing on the top, drops of red water, flowing down the stone pillars towards the ground, and some even dripped onto Ye Zhan and the others.

"Brother Ye, it's dark all around, what should we do? Where to go? After killing all the monsters that attacked them, Zeng Cheng asked Ye Zhan.

"There." Ye Zhan stretched out his hand and pointed in one direction, which was the direction in which those monsters rushed out before, although there was nothing to see around now, but since those monsters rushed out from this direction, then the other directions were likely to be dead ends, so Ye Zhan didn't even consider these directions.

Immediately afterwards, the five of them rushed in the direction where the monsters appeared before, and the depths of the cave were pitch black, without a trace of light, but these could not affect Ye Zhan, but their eyesight was not finished, as the five people kept advancing, the road ahead also became uneven, and there were even many huge potholes on the ground.

These potholes, some are very shallow, only one or two meters, but some are very deep, through these pits, you can see the water flowing in the depths of the caves, these waters are obviously groundwater, these potholes are the monsters that attacked them just now, however, these potholes did not stop Ye Zhan and the others from moving forward at all,

Five minutes later, Ye Zhan and the others came to a rock wall, and further on, there was no way out.

Ye Zhan, who did not believe in evil, ran along this wall for more than ten minutes, but it was still these stone walls, and other than that, there were only those potholes and grooves on the ground.

"It seems that the cave is surrounded by this kind of wall, and other than that, there are only those monsters left, so what is Xia Ji's plan?" Ye Zhan stood in place, stroked his chin with his hand, and began to think.

"Brother Ye, we've been turning for more than half an hour, we can't go on like this, I don't feel like anything new to discover." Zeng Cheng had some complaints on his face, and he kept running around for an hour, which made him feel a little unhappy in his heart.

"Ye Zhan, will the things that Xia Ji needs be in the groundwater?" Yu Siqi said suddenly.

Hearing Yu Siqi's words, Ye Zhan's eyes lit up, yes, he was only looking for it in the cave, so if the thing Xia Ji was drawing was not here at all, but in the groundwater below, how could he, Ye Zhan, find what he needed?

"Let's go, come with me into the groundwater." Ye Zhan snorted lightly and rushed directly towards the deeper pit closest to them, which was a pit with a diameter of about two meters, and Zeng Cheng and the four of them followed.

Entering the pit, the bodies of the five people fell towards the bottom of the cave at a very fast speed, and then, they fell directly into the water below the cave, and after diving for about four or five meters, when Ye Zhan and the others saw the scene in front of them, they were all stunned.

When they dived into the water at the bottom of the cave four or five meters away, the person in front of them was cheerful, except for a small hole above their heads, all around was water, endless water, making people feel as if they were at the bottom of the sea.

And what shocked Ye Zhan the most was that not far in front of them, probably under the water in the center of the huge cave, there was a huge crystal tower, this tower was extremely huge, covering an area of thousands of square meters, up to more than three hundred meters, like a fire launch tower, and in the center of the tower, there was a diamond-shaped crystal, the crystal was five meters high and one meter wide, erected at the top of the tower.

The diamond-shaped crystal emitted a blazing white glow, like a small sun, making the entire underwater world seem like daylight.

Ye Zhan and the five of them stared blankly at the huge crystal tower at the bottom of the water, as well as the diamond-shaped crystal at the top of the tower, their minds were full of incredible colors.

They couldn't understand why there was a crystal tower in the water below the bottom of this huge cavern, and what was this tower for?

However, although Ye Zhan didn't know anything, he clearly knew that the crystal tower in front of him was definitely Xia Ji's ultimate goal.

Ye Zhan made a gesture, and then, the five people swam towards the underwater crystal tower, but when the five of them swam to the side of the crystal tower, they found that they had underestimated the size of this tower, which was more than twice as large as when they looked at it just now, and in the diamond-shaped crystal that exuded blazing white at the top of the tower, there was a faint red light circulating.

At this time, Ye Zhan felt a tap on the shoulder, and when he looked back, he saw Zeng Cheng looking at him with a puzzled expression.

It was inconvenient to chat underwater, but Ye Zhan quickly understood the doubts in Zeng Cheng's eyes, but Ye Zhan had never heard of the crystal tower in front of him, so it was impossible to reply to Zeng Cheng's question.

Swimming to the diamond-shaped crystal ball of the crystal tower, Ye Zhan looked at the crystal ball in front of him, blazing white light, if ordinary people stayed here, it was estimated that they would not even be able to open their eyes, but Ye Zhan could look directly at the crystal ball and watch the situation inside the crystal ball.

Inside the diamond-shaped crystal ball, it seems that there is a red liquid constantly swimming in it, which is full of strange feelings.

It's just that I don't know, what is this thing for, but since it's Xia Ji's picture, no matter what it is, just destroy it directly! Ye Zhan said secretly in his heart, and then, he took out the dark gold emperor knife and prepared to destroy the entire crystal tower and the diamond-shaped crystal at the top of the tower with brute force, so that the altar array outside lost its goal, and naturally disappeared, and Xia Ji's purpose was naturally impossible to achieve.

However, what Ye Zhan didn't expect was that when he just took out the Dark Golden Emperor Knife, the weapon suddenly emitted a golden light, and then it broke away from Ye Zhan's hand.

Ye Zhan's face was stunned when he saw this scene, this kind of strange thing, he had never encountered before, the weapon would automatically leave his palm, however, what shocked Ye Zhan was still behind, when his long knife flew out of his hand, the Dark Emperor battle armor on his body was also at this time, making pieces of scales, flying away from his body, and then when he was a meter in front of him, it turned into a battle armor again.

Immediately after, Ye Zhan's battle knife and battle armor flew towards the diamond-shaped crystal at the top of the crystal tower at an extremely fast speed.

It was also at this time that Xia Ji came to the light film outside the cave, she floated four or five meters from the ground, her beautiful eyes released an indescribable charm, and her clothes were still the light green gown, moving with the wind.
