Just as she turned around, she saw the Nine Yin Demon Emperor appear here. She had just returned from injury before. She sat in front of her and knelt down at the Nine Turn Yin and Yang Sand, and then wanted to suppress her injuries here.

But in the end, I couldn't do it and left. The time followed that the change accelerated because there was no damage or any power fluctuation here, so even things that were long ago could be reproduced.

Suddenly, I don’t know how long ago I saw the Nine Yin Demon Emperor comprehending here and comprehending to achieve the Demon Emperor. Then I saw the Nine Yin Demon Emperor, who was just the Heavenly Demon Emperor, entered it for the first time. He was obviously seriously injured, but he used the Nine Turn Yin and Yang Sand to comprehend some things, and then saw her trying to break through this formation.

But every time it was not successful. Just like the instinctive sensing of flesh and flesh, Cheng Gong's analysis, this formation is a formation that combines yin and yang, and is difficult to break.

After looking around, there are not many meaningful things. Only the Nine Yin Demon Emperor got some Nine-turn Yin-Yang Sand from the surrounding corners, and often went to seclusion here to comprehend. The only thing that can be confirmed is that the Nine Yin Demon Emperor has used all kinds of attacks, and even in the later stages, this is often the object of venting the attack. Although this formation of Nine-turn Yin-Yang Sand condensed by Nine-turn Yin-Yang Sand is powerful, one advantage is that it does not fight back.

This made Cheng Gong feel relieved. He could try it himself, but it was not very useful. I didn’t expect a thorough method, which was not very effective, because when the Nine Yin Demon Emperor was the most powerful, the attack power was not weaker than that of himself, but the result was the same.

Unfortunately, there are only a limited number of people who can retreat now. There has been another powerful existence here. It seems like it was tens of thousands of years ago, and the previous ones would not be able to reproduce. If the powerful existence of the formation was really reappeared in the scene of how the powerful existence of the formation was deployed, it would have been of great help to Cheng Gong.

However, although another powerful existence only came in once, Cheng Gong could see that he must be a Demon Lord or Dao Lord realm. Because the Nine Yin Demon Emperor obtained some of the Nine Transformations Yin and Yang Sands he bombarded from this formation, which was much smaller than before. But later he seemed to have left something and never came back.

Unfortunately, even if he reaches his level, even if he uses this heaven-defying talented magical power to restore the scene before he can only vaguely see an existence, but he cannot tell who he is.

With the magic of this place, even if Cheng Gong knew that he would come in the last life, the Demon Lord must have had something to do, either dead or completely shut up. Otherwise, he would not have been able to occupy such a place like the Nine Yin Demon Emperor, and he would not have let go of such a place and care about it.

After letting the liuru return to the outer space of the Yin-Yang Cauldron in the Void, Cheng Gong also tried various attacks one after another, but the effects were average.

Although the Nine-turn Yin and Yang Sand is strong, normally the flames in Cheng Gong's small empty cauldron are also very strong. Cheng Gong even used the natal true fire, the Supreme Yang true fire, and the Supreme Yin true fire, but the effect is not great.

At this moment, Cheng Gong could truly feel the power of the person who arranged this formation back then. This power even felt like a finger close to the destruction of the Qiankun Dan Sect, or the dead dragon in the Shenlong Immortal Palace.

Yin and Yang are united. Yin and Yang are united...

Looking at the huge nine-turn Yin and Yang Sand condensed formation, how much control the Yin and Yang power can I do it, I have been working hard...

Suddenly, a thought flashed through Cheng Gong's mind, and the man sat directly in front of the formation.

Then the divine mind slowly began to merge into the formation. The formation did not have any damage power, but it was powerful enough to block everything. Perhaps it was because of the passage of time, or perhaps it was because someone's attack caused some problems in the formation of the Nine-Turn Yin-Yang Sand, Cheng Gong felt it with the inner tripod of the Void Yin-Yang Cauldron and the Daozu Token.

Cheng Gong slowly used his Yin-Yang All Things Art, and at the same time he triggered the Supreme Yang True Fire in the Yin-Yang Cauldron inside the Yin-Yang Cauldron. The Supreme Yin True Fire simulated the changes of these nine-turn Yin-Yang Sand.

"Boom..." The fusion of Zhiyang True Fire and Zhiyin True Fire was a very small amount, and it instantly ended with a bang.

Fortunately, Cheng Gong's body has strong divine consciousness now, and this level of failure has not had much impact on him. In the past, Cheng Gong condensed these two extreme forces in the Breaking Tribulation Spear. With the suppression of the Breaking Tribulation Spear and the regulation of his own real fire, he could slightly suppress these two forces, but it can only be said to be suppressed together, and there is no real integration.

Even so, its power is already quite amazing.

At this time, Cheng Gong had some new insights from this formation and gradually tried to induce a small amount of Supreme Yang True Fire, and the Supreme Yin True Fire fused in the body. But every attempt would soon fail. Every failure would be like a powerful bombardment on the body. Although Cheng Gong was controlled within the range that the body could withstand, the remaining power of each explosion was also extraordinary.

On the one hand, it is a try, and on the other hand, every failure of the fusion of strength is a test and tempering of the body again and again.

Later, Cheng Gong simply took out the Xiaoxu Cauldron and entered the acceleration space of the Xiaoxu Cauldron, and tried it with a hundred times faster time.

Outside the palace, Zhuque Tianzun was searching with Xiaojiu.

"Master, it's been almost twenty days. Brother Cheng Gong won't have any trouble, right?" Xiaojiu was very worried. Although this palace was extremely huge and amazing. But she and Zhuque Tianzun searched several times, and Cheng Gong was so empty that she couldn't find him at all.

"He won't have any trouble if anyone has any trouble. Humph, this irresponsible guy doesn't know where he has gone, so he doesn't say hello. He always talks about others like him." Zhuque Tianzun suddenly thought of what Cheng Gong said when he scolded her, and at this moment he finally had the chance to say Cheng Gong.

Xiaojiu was also worried about Cheng Gong and did not pay attention to the problems with Zhuque Tianzun's words. He followed Zhuque Tianzun to search in this very large palace group.

At this moment, more than five years have passed by Cheng Gong in the Xiaoxu Cauldron. Cheng Gong himself has not known how many times he has tried in the past five years. Various ideas and insights have been made to keep trying.

Although the amount of the ultimate yang true fire and the ultimate yin true fire are controlled to a certain extent, the power generated by the failure of the two flames in the body is still amazing and cannot withstand the number. This is different from the previous one of the single tempering. The impact force of the failure of the two extreme forces is another matter.

Cheng Gong's body had exploded for many times, and it was repaired immediately after it exploded. A huge Dao Zun Dragon Ball on the top of Cheng Gong's head had shrunk a circle.

Before, Cheng Gong used fragments of the Dao Zun Dragon Ball, but he used them himself, Yun Wuxing, Feng Wuying and others, and they also used them in other places, and there were almost nothing left now. Cheng Gong simply used a new Dao Zun Dragon Ball. Only this Dao Zun Dragon Ball that contains the power of the peak dragon king can withstand Cheng Gong's squander and consumption.

Only Cheng Gong dares to constantly merge into the Supreme Yang True Fire and the Supreme Yin True Fire in his body, the most extreme flame between heaven and earth, causing the most terrifying impact.

"Boom...boom..." Persistence, persistence, the Zhiyang True Fire and Zhiyin True Fire, which were three times stronger five years ago, but the time for the fusion was already three times higher than the previous one. But in the end, another new fusion failure came. However, after this failure, Cheng Gong, supported by the power of the Daozun Dragon Ball, his body actually resisted the impact that would almost break his body every time before.

After breaking through, Cheng Gong was immediately delighted. Although he had not yet fully integrated. However, after these five years of insight, his body had already broken through to the middle stage of Taizun, and his divine thoughts suddenly caught a trace of his feelings at this moment.

Just like when he realized the power in the Daozu token, the formation of the Nine-Turn Yin-Yang Sand became less difficult in an instant, and Cheng Gong gradually grabbed a slight change.

"Boom!" The divine thought took another step in an instant. This was a new insight. The divine thought directly reached the peak of the Heavenly Lord. Cheng Gong's body power surging, madly absorbing the power in the Dao Zun Dragon Ball. After five years of absorption, extreme consumption and use, it was nearly two thousand days, and thousands of times of crazy consumption and activation every day. Cheng Gong's own magic power also absorbed the power in the Dao Zun Dragon Ball and steadily entered the peak of the Pure Sun Tai Zun while his body and divine thoughts broke through.

When the power increased, Cheng Gong's divine thought moved and had left the Xiaoxu Cauldron, and then he put the Xiaoxu Cauldron into the outer space of the Yin-Yang Cauldron in the Void.

If you sit down and cannot realize the truth, you cannot have some insights. It will be meaningless if you continue like this. Cheng Gong knew that with his current situation, he still could not truly break the formation condensed by the nine-turn Yin and Yang Sand.

Although the unity of yin and yang is achieved by using the Nine-Turn Yin and Yang Sand, this realm is also admirable. This is definitely not the level of ordinary Taoist lords and demon lords. But now even Cheng Gong dares not guess what this person is intended.

And what exactly is sealed here? From the outside, you can vaguely see inside like a fairyland, whether it is an illusion or a real lead to a certain place.

And if you can feel the power of the outer fragments of the Yin-Yang Cauldron inside, the things here are definitely not very good.

But no matter how good things are, you can't be impatient. Cheng Gong suppressed his mentality. In the past five years, he has not only increased his strength in all aspects, but also with the help of the nine-turn Yin and Yang sand condensation formation that combines Yin and Yang, his control over the Supreme Yang True Fire, the Supreme Yin True Fire and his own natal true fire has become different from the past.

You can suppress them in your own body in a short time. If you use the help of the robbery gun, the power it can produce is several times that of the past, and the various effects are much stronger.

But now it's time to leave. Cheng Gong thought that he had raised his hand and appeared in his hand. Cheng Gong instantly operated the ultimate yang true fire and the ultimate yin true fire that were ten times stronger than before he had endured here before entering the place, and his natal true fire also entered it.

The two extreme flames run at an extremely fast speed to condense and compress, and there is a slight fusion. Among them, Cheng Gong's life true fire is checking and balanced in the middle, and finally a drop of flame condensed light spot appears on the tip of the spear breaking spear.!~!
