After breaking up with Pooh, he advanced for a while, and the aura in Ziyan's flying array was almost exhausted, so he fell to the ground and asked Tian Xu to charge the array. Most of the aura in her body was dispersed, and she couldn't support her to fly by herself, so she could only use the array weapon to fly, which made her feel very unhappy, so she brought up the matter of Ning Dan again.

Tian Xu said: "Do you still remember the method of walking in the sky that I used when I accepted those people from the Three Immortal Views as my junior brother? That is a flying method that can be achieved with the sun-chasing technique, don't you want to try it?"

Ziyan remembered how Tian Xu walked in the sky that day, and thought it was quite fun, but the force required to walk like that was quite large, and the speed was a little slower than flying. After she saw it that day, she didn't think that she could do that herself, and when she heard Tian Xu say it, she immediately tried it.

Ziyan's Sun-Chasing Technique realm is one step lower than Tian Xu's, and it is still a little difficult to walk in the sky. Tian Xu taught her some skills to exert her strength, and she took a few steps and ran in the sky. It's just that she ran a little staggeringly, and the force was not quite correct, causing a lot of strength to be wasted, and she only ran for ten minutes, and she felt a little tired.

Ziyan is a character who does not admit defeat, and it is fun to run in the sky, she only rested for a while, and then ran all over the sky again.

They were not in a hurry, Tian Xu watched Ziyan running around in the sky, and he followed her forward or backward, helping her when she was about to fall. Ziyan didn't like Tian Xu's way of guarding like an old hen, so she drove Tian Xu into the distance and practiced with great interest. Her sun-chasing trick actually has a lot of power, even if she falls from a height of one hundred and ten meters, she will smash a hole in the ice below at most, but she herself will not be injured, Tian Xu is no longer worried, and only stays on the side to watch the excitement.

In this playful practice, Ziyan's skills in walking in the air became more and more proficient, and finally stopped falling from the air and walked much more steadily. Tian Xu was happy to see it, and he stopped flying, walking in the air like purple smoke, and the sound of the two of them vigorously stepping on the air resounded in this inaccessible ice and snow world.

Ziyan sometimes deliberately fell from the sky, pretending to fall accidentally, seeing that Tian Xu was amused and shook his head helplessly, while he laughed on the side. When she fell again, the snow under her feet was vigorously stepped out of a large hole, and she fell straight down the hole.

This kind of thing has happened many times, and Tian Xu didn't care about it, but after a while, he didn't see Ziyan coming out of the hole, and he was still a little uneasy. The sense of smell was severely suppressed on this ice and snow wasteland, and he took a few big strides to the vicinity of the entrance of the cave, and the spiritual realm shrouded the big hole, but the scene he observed made him anxious all of a sudden: the purple smoke was gone!

The ice here is less than ten meters thick, and underneath is a cavity created by the ebb tide of the sea. The sea here should not be too deep, the ice is more than two meters above the bottom of the sea where the sea recedes, and the hazy sky light shines through the hole, making it form a dark pale blue inside, some mussels live in the cracks of the rocks at the bottom of the sea, and the purple smoke does not leave footprints underneath, or even any traces!

Tian Xu's heart fluttered suddenly, Ziyan's aura could not support flight, if she landed, how could she not leave footprints? If she did not land, relying on the air she had just learned to walk, there would be an obvious loud noise, and now that she had no trace, something must have happened. The instinctive olfactory image also told him that something was wrong, the smell of purple smoke did not reappear when it reached the bottom of the ice cave, where did she go?

Tian Xu forced himself to calm down, mobilized all his senses, the olfactory image quickly switched between positive and negative colors, and the spiritual realm also used various modes to cross-scan, and finally, directly below the ice cave that Ziyan stepped out of, and an abnormal space caught his attention.

It is a space less than ten meters in diameter, just half a meter below the ice. Strictly speaking, there is nothing special here, but this space is too "clean", so clean that there is no smell, and there are no characteristics, not even the smell of sea water and the abnormal smell in the air, and under this space, the ice and snow that broke when the purple smoke stepped on the ice layer are gone, such a clean space, can only show one problem, that is, there is a special hidden space here, and the purple smoke has fallen into this space!

Tian Xu didn't have the heart to think about whether it would be dangerous, he immediately jumped into the ice cave after discovering this anomaly and landed on the hidden space door.

After landing on the door of this space, Tian Xu felt as if his body had entered a vacuum environment, he couldn't breathe, he couldn't see anything, all his senses seemed to be blocked, but fortunately, there was still a role in the spiritual realm, so that he could feel that the space around him was rapidly changing at a high speed far beyond his cognition.

It seemed like only a few seconds had passed, and it seemed like a long time had passed, and he felt a shock in his body, and all his senses seemed to return, and his body had come to a strange space, in the water. This water has a certain salty taste, it is seawater.

The spiritual realm told him that it was a completely unfamiliar environment. He didn't dare to use his cheek breath easily in this water, God knows if there was anything strange in this water. Fortunately, he is no longer in the weak state when he was crushed under the waterfall, even if he holds his breath, he can hold on for a long time, and his movements will not be affected by the basics.

Tian Xu slowly floated to the surface of the water, felt the environment in this space, and found that it was very empty, there seemed to be no other people or animals, and there were no creatures in the seawater, not even tiny algae, just like a lifeless planet.

He let go of his divine sense and searched for the traces of Ziyan, but found nothing, Ziyan had just fallen into this space, but it was not near him at this time. Let go of the olfactory imaging on the sea, let the sense of smell and vision go far, the scenery within a radius of more than ten kilometers completely fell into his mind, so that he had a better understanding of the surrounding environment, but there was no shadow of purple smoke, and there was no smell of purple smoke, and the purple smoke seemed to disappear all at once, making it all seem a little weird.

Tian Xu stabilized his mind, he couldn't panic now, only by calming down could he look for Ziyan.

This space is quite strange, the sky is gray, there are no sun, moon and stars, no clouds, no wind, but the air seems to be similar to the earth, except that the oxygen content in the air is slightly lower than that of the earth, and the aura is far more than the earth, reaching a concentration similar to that in the medicine king bucket.

As far as his olfactory image and gaze could see, there was no trace of land at all, only some hills of land suspended in the air, and some of them were in contact with the sea below, but Tian Xu could be sure that even if these hills penetrated into the water, they did not reach the bottom of the sea, but were also suspended.

Some of the hills are ruined buildings, mostly made of boulders, and all the buildings are desolate, and it is clear that no one has been here for a long time.

The depth of the seabed varies, and the depth here under his feet is more than a thousand meters, but in some places it is only a dozen meters deep. Olfactory imaging can reveal what is going on on at the bottom of the sea, which is just as inhospitable.

On closer inspection, he found that it was not completely devoid of life, and that on the bottom of the sea and on the hills, there were some sparse plants growing, and these plants were of all kinds, most of which were different from the plants of the earth.

Tian Xu tried to shout, "Ziyan, can you hear my voice?"

His cries echoed through the space, reflecting off the surface of the sea and the surrounding hills, forming a huge echo. Tian Xu listened kindly, but did not hear Ziyan's response. This space is very large, and he can't perceive where the edge is for a while, and it is estimated that Ziyan and he were teleported to a different place by the space door, and they can't be contacted for a while.

He suddenly became nervous, Ziyan's Jin Dan had not been re-condensed since he dispersed that cultivation distress, and she only had a small amount of aura on her body that could be used, only a little stronger than the average Qi Gathering Dacheng Realm cultivator, and if she encountered danger, she could only rely on her physical body to deal with it with the Sun Chasing Technique. Purple Smoke's Sun-Chasing Technique has now reached the second level and sixth form, and it should barely be able to fight against a fifth-level peak demonic beast, or a ninth-order cultivator of Ning Dan. It's just that without Jin Dan, she has a lot of spells that she can't use, including flying and diving skills.

Fortunately, Ziyan has the flying and diving array that she has refined for her, and with this thing, she should be able to achieve good mobility in the air and in the water. It's just that Ziyan didn't take the array weapon she gave her with her? If she put it in the Medicine King Dou, it would be miserable. She should have carried the flying array with her, and she used it to fly in the sky before practicing air walking. It's just that the aura in the array seems to be running out, and she has to quickly replenish the aura to the array.

The only way that purple smoke can replenish the aura of the array is to use the diving array to filter the aura from the seawater, which is much more efficient than putting it in the air and letting the array absorb it by itself. If it is artificially charged, the aura in Ziyan's body is insufficient and cannot be completed. Another way is to use the Qi Replenishing Pill to charge the flying array machine, which is quite simple. It's just that the number of pills that Ziyan carries with her shouldn't be too much, she is lazy and doesn't want to bring too many things.

Thinking of this, he suddenly thought of a serious problem, and he didn't know if she had brought the Yiguang Sword with her, if the Yiguang Sword was not there, she would be missing an important talisman chip in case of danger.

Tian Xu hurriedly probed his divine sense into the Medicine King Bucket and asked if the Yi Light Sword had been taken away by Ziyan, but he was surprised that his divine sense could not enter the Medicine King Bucket!
