The whole hollow island is funnel-shaped, thick at the top and thin at the bottom, with only a circle of three zhang wide walkway at the top, and a deep pit in the middle, which extends to the bottom of the river at all. With this peculiar shape, it is difficult to imagine that this is a naturally formed island, not man-made. But this is indeed a natural formation, otherwise who would have made such a large island?

On the outer corridor of the island, the masked girl in a yellow dress and purple gauze looked at the dark pit in the middle, but there were a few spatial cracks from time to time, and said, "We can't go down yet?"

There are eight people patrolling this Trap Island, and each of them has a cultivation of at least the Yuan Infant Five Transformations, this kind of character is definitely a grandmaster-level figure outside, but he is just a guard on the Trap Island, so it is conceivable that the Trap Island must be hiding some big secret!

"Why can't you go down?"

Yu Qingwu looked at the girl with a smile and said, "Even if the Sea King Palace is not on the Sky Island, there must be some other secrets here, we finally came, it is impossible to return empty-handed, right?"

Since he had already decided to look for the Sea King Palace, how could he retreat cowardly when he was on the empty island that was very likely to be related to the Sea King Palace? As for the danger...... Although he doesn't have a life-saving treasure like the Shifting Talisman, he does have the Escape Magic Technique of Shifting and Transposing!

There may be some unimaginably powerful characters in the depths of the Trap Island, but he is not useless, once he encounters a master he can't compete with, he can resist the instantaneous kung fu with Xiaohong's cultivation, and in this instantaneous kung fu, it is enough for him to perform the transformation and transposition and take Xiaohong away.

As for the girl with a mysterious origin in front of him, he is even less worried, since people were able to escape with a thousand-mile transfer charm last time, if they encounter danger again this time, they may not be able to take out a thousand-mile transfer charm! Besides, he has only had a two-sided relationship with her, and whether she is dead or alive has nothing to do with him, and the only thing that is a little troublesome may be the 'poison' she gave herself and Xiaohong. But he didn't think much of it.

"Great!"

As soon as she heard Yu Qingwu say that she wanted to go down, the girl immediately jumped up excitedly, which only caused Yu Qingwu to roll her eyes.

After the girl's mood calmed down, Yu Qingwu asked, "Will the Technique of Change be?"

"I'm a martial cultivator, how can I change the technique!" the girl said with a roll of her eyes.

Yu Qingwu raised his eyebrows, originally he thought that the girl in front of him was a Taoist cultivator, but he didn't expect her to be a martial cultivator, which really surprised him. After shaking his head and smiling, he said, "Then you relax and don't resist, I'll make you small!" After speaking, he pinched the seal with his right hand again and again, and after a light snap in his mouth, his fingertips pointed at the girl, and the bright light flashed, and the tall masked girl immediately became only the size of a grain of rice.

The masked girl who had been spinning around on the ground looked up at Yu Qingwu, who looked up like a giant in the sky, and said, "Spells are so fun, it seems that I will have to learn a few things in the future!"

She is not stupid, and she will not be ignorant of the reason why Yu Qingwu made herself smaller. If you want to escape the surveillance of others, becoming smaller is definitely better than stealth!

Yu Qingwu didn't reply, and after nodding at Xiaohong, he said 'change' in his mouth, and he became the size of a masked girl, and then, Xiaohong, who was proficient in the seventy-two changes of the earth, also shrunk.

The two men and the beast glanced at each other, and then jumped down from the pit in unison. Although their bodies have become smaller, their flexibility has not been limited, but has increased, and in the process of sliding down the stone wall, they dodge left and right, dodging one after another mysterious spatial cracks, reaching the bottom of the deep pit.

As expected, the deep pit of this hollow island leads to the bottom of the sea, which can be thousands of feet deep. After reaching the bottom, it is a straight artificially dug passage, the height and width of the passage are three zhang away, and the end is not visible at a glance.

Maybe it's because of the fact that we went to the bottom of the sea, or maybe it's man-made, and it's no longer full of spatial cracks like outside, just like ordinary places.

Because of the placement of the Night Pearl in the passage, it is not pitch black, but it is not very bright. On both sides, there was a man in black standing every five feet, all holding his breath and closing his eyes. At the moment when the two of them slid to the bottom, the first few people opened their eyes and looked at the entrance, but after seeing nothing, they closed their eyes again.

When the people opened their eyes and turned their heads, both of them and the beast were startled, and when they were about to leave the island, the few people who had not found anything closed their eyes again, which made them breathe a sigh of relief. At this time, they have restrained their breath, they are like three flies, if others don't look at them directly, it will be difficult to find them at all, and they don't want to be in a state of invisibility, some people with sensitive perception can vaguely feel that if they investigate carefully, they will definitely be able to find something catty.

"I was found in this passage last time. The masked girl said to Yu Qingwu in a divine voice: "It's strange here, there are prisons at intervals on both sides, and there are several people in it. At first, I thought that this was the place where the Great Xia Dynasty imprisoned the enemy, but at that time, I heard a person say, 'It's almost successful' Yunyun, and I thought that this place might be related to the Sea King Palace. Maybe they're going to take those who are being imprisoned to do sacrifices or other rituals to open the Sea King's Palace!"

Hearing the girl's divine thoughts, Yu Qingwu nodded, motioning for the two to wait for him here, while he walked cautiously against the wall. He breathed a sigh of relief when he crossed the first 'giant', and only then did he make sure that those people hadn't found themselves.

To his left was a dark metal fence that separated a stone chamber two feet long and wide. There were five people in the stone room sitting on the ground against the wall, and their mental state did not seem to be good, and they felt like they were half asleep and half awake.

"Huh?"

When he saw the faces of those people clearly, Yu Qingwu frowned, and those who were imprisoned had a mark on the center of their eyebrows, which was a combination of two hooks, one positive and one negative, and it looked like they had an extra eye in the center of their eyebrows from a distance. This kind of imprint is generally only drawn on the eyebrows of Shu people, so it is also used as a symbol of Shu people.

If there was only one Shu person in the stone room, he wouldn't be surprised, but the five people in the key stone room all had that strange mark on their eyebrows, which means that they were all Shu people!

Yu Qingwu, who wanted to enter the cell to take a look, took a step forward, but then retreated. The metal fences were separated from each other, and it seemed that he could easily walk in, but he was not allowed to pass through the barrier, and if he broke through, it was very likely to trigger and be discovered by the people here.

Thinking of this, he gave up the idea of entering the cell, and beckoned to Xiaohong and the masked girl at the entrance to let them in, and walked cautiously inside.

Walking through one cell after another, Yu Qingwu and the masked girl became more and more surprised, because the people in each cell had a mark similar to an 'eye' on the center of their eyebrows, which was the so-called Shu people. Now it is almost certain that all the people imprisoned here may be Shu people.

Moreover, Yu Qingwu also found that the further into the cell, the more vigorous the blood of the people imprisoned inside. For mortals, the more vigorous the qi and blood, the better the body and the longer the lifespan, while for the monk, the more vigorous the qi and blood, the higher the cultivation.

What made him a little puzzled was that the people imprisoned here were all mortals, but some mortals' qi and blood were not as bad as those of monks with three or four hundred years of skill, under normal circumstances, this kind of thing was almost impossible to exist, after all, the longest life span among mortals was at most in their early 100s, and the life span of a monk with three or four hundred years of skill was generally two hundred years away, how could a mortal have a life span of two hundred years, and his qi and blood were comparable to those of a monk in this realm?

"Is it because the true qi and mana have been abolished?" Yu Qingwu thought in his heart, there is indeed such a possibility, but the key is that the people here are trying to abolish the people who are arrested and cultivate, and leave their qi and blood empty? And the people who are arrested are all Shu people!

At this time, the two men and one beast had already walked thousands of zhang away, and there was no longer endless darkness in front of them, but a hidden stone door appeared. Just as Yu Qingwu was about to step forward and enter the back of the stone door, the masked girl beside him suddenly grabbed his right arm and shook it, he frowned slightly, and looked back at the masked girl suspiciously, not understanding what she wanted to do.

The masked girl didn't speak, but just raised her hand and pointed to the cell on the left, motioning for Yu Qingwu to look. The latter turned to look at the cell on the left, but when he saw it, his whole body was shocked, and his eyes widened.

Walking through hundreds of cells in front of him, he looked at almost every one of them, and the people imprisoned in them were all Shu people, which made him have to think that all the prisoners in the cells were Shu people. But the three people imprisoned in the cell near the stone gate did not have the mark like an eye in the center of their eyebrows, in other words, they were not Shu people at all!

In addition, he still knew the young man in the prison cell who was wearing a white Taoist robe embroidered with gossip on the front and back of his chest, because that person was also a disciple of Kunlun, if he remembered correctly, he was still a disciple of Taiji Peak!

Before the Kunlun disciple experience, he had seen this disciple on Kunlun Mountain, although he didn't know the name of this person, but this person would greet him almost every time he saw him. But since the training, he has not been seen again, which means that he is very likely to have disappeared during the training and is classified as one of the dead disciples!

Yu Qingwu never expected that he would see a Kunlun disciple here, he hurriedly looked at the opposite cell, but found that the four people in the opposite cell were not Shu people. Except for the two cells closest to Shimen, the people in the rest of the cells were all Shu people!

"Shu people...... Was it made?" Yu Qingwu popped up such an idea in his mind, although it seemed ridiculous, but it was not impossible, because only in this way could it be explained that only the people in the two cells were not Shu people, and the people in the other hundreds of cells were Shu people, after all, if the people on this empty island were only arresting people, there was no need to arrest nine out of ten Shu people, plus a few people who were not Shu people.

Rattle......

At this moment, the hidden stone door slowly opened, making a piercing sound that made people grind their teeth. Yu Qingwu, the masked girl, and Xiaohong, the two beasts, were immediately stunned, leaning against the wall and holding their breath, not daring to make a sound.
