Xiao Lingyu had flown up before, but he still flew up again this time.

The top of the main hall is also divided into two, all of which are covered by red special tiles, seamless and solid. If you look carefully, you can see that there are faint spell lines flowing on those tiles.

Xiao Lingyu, who had come up once, knew that it was difficult to get useful information from those spells, because the spell should come from the Heavenly Master. It was very clever and could not be understood by him at all. Even Peng, who was in the same vein with the Heavenly Master, could only shake his head after seeing the spell lines.

Xiao Lingyu's attention was not on those lines, but very carefully looking for abnormalities.

There is a long beam across the center of the hall roof, which is covered by semicircular tiles. It is like a dividing line. It divides the hall into front and back. There is one kind of magnetism in the front and another in the back.

Xiao Lingyu thought the key to the problem should be on this long beam, but he looked carefully and found nothing.

When Xiao Lingyu was about to give up the roof, he just jumped off the roof, but he found that the section at the end of the long beam was a circle of Yin-Yang fish.

The main hall is very high, so when you stand at the foot of the main hall and look up, you can't see the section at both ends of the long beam, and you don't want to look over. Even if anyone sees it, they won't care too much about the emblem of the yin-yang fish. After all, it's too common.

But Xiao Lingyu suddenly thought of two words - Tai Chi.

The figure of Yin-Yang fish is actually a Tai Chi diagram, which is composed of black fish, white fish and black-and-white fish eyes. This is left by the strong people on earth in ancient times, and it is said that Tai Chi produces two instruments.

The reason why you think of Tai Chi when you see this yin-yang fish emblem is also because the name of the hall "bipolar hall" contains the word "pole".

And Xiao Lingyu vaguely remembered that Zhong Zhi had guessed that the Heavenly Master was likely to be a strong man on the earth in ancient times.

"Tai Chi begets Liangyi... Tai Chi begets Liangyi..."

Xiao Lingyu hung on the side of the top of the side wall of the hall, stared at the circle of Yin-Yang fish emblem and recited it repeatedly.

The theory of Tai Chi is rarely mentioned in the spiritual world. It seems that this has been gradually forgotten by the monks below the divine world with the boundary.

However, after understanding some of the supreme principles of chaos, Xiao Lingyu knew that Taiji generates Liangyi in the eyes of monks, which means that chaos is divided into yin and Yang. Taiji is chaos, which is the unity of vitality, and Yin and yang are divided by chaos, which promotes the formation and development of all things in the world. All things in the world also have Yin and Yang.

When Xiao Lingyu thought of the key point, he found that the yin-yang fish in the long beam section turned slowly.

But when he noticed this, he looked carefully. The yin-yang fish seemed to have never moved.

Xiao Lingyu knew that he could never be dazzled because he had seen it for too long. When his cultivation reached his level, he could not be dazzled at all.

So he continued to think and stared more attentively at the circle of Yin-Yang fish.

Before long, he saw the yin-yang fish emblem turn again, but it soon stopped, and there were no other abnormalities.

Xiao Lingyu thought it would be of little use just to guess and observe by himself. Therefore, later, he hit the yin-yang fish emblem with a chaotic magic.

The chaotic magic sank into the yin-yang fish, but it just let the black-and-white fish eyes bloom a faint light. However, in this process, Xiao Lingyu found an anomaly, that is, there was a little fluctuation on the side wall here. The fluctuation was very weak, which would be difficult to find if he didn't stare at it all.

So Xiao Lingyu injected a chaotic magic into the Tai Chi picture, and the side wall fluctuated slightly.

Xiao Lingyu thought that there was too little chaotic magic entering the Tai Chi diagram at one time, so he continuously increased the output of chaotic magic. Just as he expected, the more chaotic magic entering the Tai Chi diagram, the more the side wall fluctuated.

Xiao Lingyu's spell casting here naturally attracted the attention of the strong in the three realms, and everyone approached one after another.

Xiao Lingyu didn't stop because everyone came. He continued to inject chaotic magic into the yin-yang fish, but until he consumed one third of his power, he could only make the side wall fluctuate and couldn't make a further breakthrough.

During this period, Xiao Lingyu also tried to turn the power of chaos into yin and Yang. Although the Yin and yang energy here will not collapse like that on the back wall, it will also be absorbed by the Tai Chi diagram. The effect can be similar to the magic of chaos, so Xiao Lingyu didn't do it again.

In such a place, surrounded by the strong in the three circles, Xiao Lingyu naturally won't let his skill consume too much. After he lost some of his skill, he resolutely stopped, and then took out pieces of divine stones to restore his skill.

Seeing this situation, other strong people also put their skills into the Tai Chi diagram. Although the Tai Chi diagram also absorbed their skills, the imperial friars' skills couldn't make the side wall react at all. Only when the divine power of the respected strong people sank into it, I would make the side wall fluctuate a little, but compared with the fluctuation that chaotic magic can make, The fluctuation created by the divine power of other respected and powerful people is obviously much weaker.

From the fluctuating reaction of this side wall, the respected strong people in the three circles were surprised to speculate that their divine power was not as good as Xiao Lingyu's skill in quality. In fact, those respected strong people who had fought with Xiao Lingyu had realized this for a long time, but they would find various reasons in their hearts not to admit it.

After Xiao Lingyu's Kung Fu recovered, he tried his best to encourage his kung fu and put it out in front of him.

After feeling the terrible power contained in the energy group in front of Xiao Lingyu, almost all the strong men in the three realms retreated at the same time.

This time, Xiao Lingyu poured out one-third of his power, and then hit it at the Tai Chi diagram.

Taiji still didn't refuse Xiao Lingyu's chaotic magic, but then the two fish eyes rushed out two strong lights, and the side wall fluctuated more violently, and a side door was revealed.

But strangely, the side door was not clear. Although it did not disappear after the fluctuation of the side wall stopped, it was obviously unable to allow people to pass.

The side door has been revealed, which makes everyone see the hope of entering the bipolar hall, so they work harder to pour their skills into the Tai Chi diagram.

This kind of Power Infusion consumes a lot. A respected strong man poured half of his power out, which will not bring much obvious fluctuation to the side wall, but will gradually make the side door clear.

You can't beat all your skills in one breath. You will retain at least half of your skills. As long as you consume 50% of your skills, you will stop immediately, and then use the divine stone to restore your skills.

Fortunately, everyone can see that the side door is gradually revealed. Otherwise, no one will waste their skills like this.

But even if the three strong forces work together, the side door is just constantly clear. Look at the speed. It will take a long time for the side door to condense into essence.

Fortunately, everyone here is well prepared. They not only brought a lot of pills to heal wounds and restore their skills, but also got countless divine stones in the first day. Otherwise, it's really difficult to support them.

In order to open the side door as soon as possible, everyone directly absorbed the divine power in the divine stone, and did not refine it carefully, so they put that part of the not pure power into the Tai Chi diagram.

But with the passage of time, everyone gradually found that the sacred stones they got in the first line of the mine were decreasing, and they were consumed at this rate. I'm afraid that before long, all the sacred stones they had worked hard to mine would have to be consumed.
