Tian Xu used electromagnetism to attack the trapped array in this heart hall this time, consuming a lot of spiritual energy and exhausting his body and mind. However, it is not without benefits, and he has gained a lot of experience in the use of electromagnetic waves after using them with all his might. Even, his understanding of aura and formation has gone to a higher level.

Some time ago, he had the feeling of condensing the pill again, but it was not very convenient in the ocean, so he planned to condense the pill with Ziyan after going ashore. At this time, he got a new understanding, and Ning Dan's desire was stronger. However, this Sea King Palace is obviously not a good place for Ning Dan, and he can only continue to suppress this Ning Dan's desire, and wait until Ziyan is rescued and out of this Sea King Palace.

Tian Xu's lost aura is not too much trouble to replenish, he is still like before entering this heart hall, diving into the water and swimming forward to absorb and replenish the aura. At the same time, he also compressed the excess aura filtered by the diving array into several blank arrays carried in the space ring, including the flying array that had not been refilled with aura after Ziyan used up the aura, and a special energy storage array that he had taken the time to make before.

Speaking of this energy storage array, it is also a thing he made out of desperation. This array has no special function, it can only be used to store aura, to cultivate in places where aura is insufficient, or to quickly recharge some array weapons. This energy storage array can compress the spiritual energy into a form similar to the golden pill and store it in the array, and the amount of spiritual energy stored is still quite a lot, at least one-third of the size of Tian Xu's own golden pill. For ordinary cultivators at the peak realm of the Ning Dan, all the aura in the golden pill will not be more than the aura in this array, which is very amazing.

Tian Xu also made this thing for Ziyan. He had never been worried about Ziyan's lack of aura before, he just thought it was too troublesome to replenish Ziyan's flying array and other arrays many times a day, so he made this treasure. As mentioned earlier, Ziyan has actually learned to condense the flying array by herself, and the reason why she still uses the flying array is very simple, that is, the aura in this array is not like the aura in her own body, which needs to be collected bit by bit through cultivation by herself, and the flying array only needs Tian Xu to be full of aura between waves of her hand to support her to fly for a long time. To put it bluntly, Ziyan was too lazy to use the flying formation she had condensed, so she often used the flying array that Tian Xu had refined for her.

Later, her Jin Dan was dispersed by Tian Xu, and Ziyan had more reason to use the array to fly, as for trying to fly by herself in the state of not condensing the Dan, or using the thing that Tian Xu had just taught her to use the sun-chasing technique to walk in the air, she tried it and still used the array weapon as an excuse to "be too tired". Ziyan was originally dissatisfied that the array made by Tian Xu could only fly continuously for about an hour, if she saw the baby that Tian Xu made for her that could maintain the flying array for more than ten hours in a row, she would definitely be so excited that she couldn't close her mouth.

After Tian Xu swam for a while, when he flew into the sky to look at the hill in front of him, he found that the psychedelic formation he had been guarding against had not appeared, and his swimming had not been affected. When the aura in his body and the aura in the array were almost replenished, Tian Xu finally came to this hill.

This hill was different from the hill where the Heart Hall was located, there was no formation to shrink or enlarge it, but it was like a barren mountain without the slightest spirituality, and there was not a trace of human population in sight.

Tian Xu rose into the air, rose to a height of several hundred meters, looked down at the sea surface in the ocean around the hill, and after various observations, he found that there were some inconspicuous abnormal fluctuations on the sea surface. After careful observation, he found that in every fluctuation place, there should be one or two or three cultivators trapped in it, trying to find a way to fight fiercely against the formation that trapped them.

"Could Ziyan be here?" Tian Xu muttered to himself. Since he suspected that Ziyan was also trapped in this formation, Tian Xu flew towards the closest fluctuation place to him. The range of fluctuations in this place is not large, Tian Xu's domain easily controlled this place, and when he looked at the people in the formation who were frozen by the domain, he saw a white bear crashing inside without a head.

At first glance, Tian Xu thought it was the sixth-level spirit beast polar bear that he had just broken up, but the smell information clearly told him that it was not the bear. The bear had the aura of a demonic beast on its body, but he wasn't sure if it was a demonic beast or not. He was a little confused, was it a demonic beast or a spirit beast? No wonder the mirage king told him that he couldn't tell if it was a demonic beast here, and it turned out that it was true.

However, Tian Xu has another way to distinguish it, that is, the method obtained on the bones of those demonic beasts on the bottom of the Kamchatka Peninsula. He shrouded the bear's head in the realm, and soon discovered that there was an area on the bear's forehead bone that was particularly sensitive to aura, so there was no doubt that it was a demonic beast.

When he first got this method of distinguishing demonic beasts, he still felt very chicken, thinking that it was a completely non-existent method of distinguishing them, but he didn't expect to use it soon in this Sea King's Palace.

Since it was certain that it was a Warcraft, he was no longer polite. After using the domain to imprison this small trapped array together with the fifth-level demonic beast bear trapped inside, Tian Xu caught the white bear, he didn't have the heart to study it, or ask it anything, and then pinched it to death and put it in the space ring, and then rushed to the next trapped array.

In this way, he inspected the seven trapped formations in the vicinity in a row, killed four demonic beasts, and rescued two spirit beasts and a Western cultivator from inside. The level of the two spirit beasts is not high, all of them are level four, and that Western cultivator is the seventh order of Ning Dan, and his strength is not strong, and he followed behind him after being rescued by him. The difficulty of the trapped array in this Sea King Palace varies, but it will not adjust its difficulty because of the strength of the cultivators trapped in it, after these cultivators with a low realm are trapped, it is extremely difficult to get out, if there is no Tian Xu to save them, most of them will be trapped and die in it, becoming the nourishment for the Sea King Palace to replenish their vitality.

Tian Xu glanced around, and saw that there was no more trapped formation—but maybe there was still a trapped formation, but he didn't find it—and walked towards the palace on the hill.

The hill in front of you is about 20 zhang high, the area of the top of the mountain is more than 100 acres, there is a majestic palace built on it, Tian Xu fell in front of the palace door, see that this palace seems to be only a large room, but the area is twenty or thirty acres, built in the corner of the mountain, the gate of the palace is open on the side near the sea, the large open space behind the palace is foggy, you can't see what is inside, and you can't enter directly, it is estimated that if you want to enter there, you need to pass through this palace.

The gate of the palace is closed, and a plaque hangs above the door, on which are written in ancient characters with the three big characters of "Tongxin Palace". The Western cultivator and the two-headed spirit beast that he rescued also followed him and landed in front of the door, and when he saw him looking up at the plaque, the Western cultivator asked, "Senior, what are the words written on this plaque?"

Tian Xu saw that this cultivator was already in his forties, and when he heard him call himself a senior, he had a strange feeling in his heart. Although in this cultivation world, the realm is respected, and there is no distinction between respect and inferiority by age, but Tian Xu's age is too young, and the time he has entered the cultivation world is too short, he is still not suitable for this kind of name. Hearing the man ask, he said: "I'm not a senior, and there is not much difference between you and me, don't call me a senior, my name is Tian Xu, you can call me by my name." On this plaque is written the three words 'Tongxin Temple', which is an ancient script, which is completely different from the modern script. ”

The Western cultivator said, "Then I'll call you Mr. Tian, my name is Jensen, I'm a monk from the Holy See, you can just call me by my name." ”

The two spirit beasts that were rescued were a big turtle and a fish with armor, they were both fourth-level spirit beasts, and they couldn't communicate with humans as freely as fifth-level spirit beasts, but they were already able to clearly understand the divine sense signals sent by Tian Xu, and they could also respond simply. They don't have names, Tian Xu named the turtle Bai Qiren, and the fish was called Bai Kainan. The name he originally gave to the beluga whale was Bai Yuan, and Winnie the polar bear was changed to Winnie Bai by him, both of whom had the surname Bai, so he used it all the way. As for the White Seven Ninja, it was inspired by the Teenage Mutant Ninja Turtles, and the White Armored Man was because he was a male fish wearing armor, and this guy's body was strong and fierce, and he was worthy of the male character in his name.

The two younger brothers didn't care about the name of the palace, they just wanted to know what the hell was in the palace.

Tian Xu stretched out his hand to push the door of this concentric hall, and found that the door was closed quite tightly, and he needed some strength to push it open. However, Tian Xu's huge power from chasing the sun was obviously enough for this gate, and the gate was pushed open with a creak, and Tian Xu stepped into the hall. Jensen, Bai Qiren, and Bai Kainan followed behind Tian Xu and also walked towards the hall.

When the three younger brothers walked into the gate, Tian Xu found that the power of the gate was several times larger at once, and he wanted to shut out the one person and two beasts behind, it seems that this gate is also a heavy test for the practitioners, if you want to enter this concentric hall, you must be able to push open the gate, if you want to bring people in, you need to bear the test power of the people you bring at the same time, so that if you want to bring many people in, the difficulty will increase exponentially. He increased his strength to hold the door, allowing one man and two beasts to enter the temple.

After entering the main hall, Tian Xu was taken aback by the situation here, the main hall was very empty, which was not unexpected to him, but inside the empty hall, there were more than a dozen cultivators sitting. The composition of these cultivators was very complex, including six demonic beasts, three demonic cultivators, one spirit beast, and four earth-native cultivators, and with the addition of the four of them, a total of eighteen people.
