They are already in the core area of Zhilei mountain. If they move forward, they will always encounter thunder dragons, and the intensity of thunder will increase ten times. Even ye Hongyu can't guarantee Fang Yun's safety.

However, there are two places in the core area where a large number of sacred air masses are bred, and there is even a sacred gas source in one place. If not, it will be a waste. The key is that the current sacred air mass can not condense the ninth Wentai.

What Fang Yun wants most in weaving Thunder Mountain is actually the thunder bones and war bones of the dragon family, but he hasn't met any of them. In addition, the holy Qi group is not enough, so he hasn't done his best.

However, if you don't become a great Confucian and have no spirit skeleton of the emperor, entering the core of Zhilei mountain is the way to seek death.

Fang Yun thought for a moment and said, "Mr. Hongyu, I can't go deep. You and I make a deal. You send me away from Zhilei mountain. I'll tell you some topographic maps of the core of Zhilei mountain."

"Yes." Ye Hongyu naturally knows that Fang Yun is evading the law of the dragon family as before, and divulging the secrets of the dragon family is a great crime. However, if he uses the secrets that will not endanger the survival of the dragon family to make transactions that are beneficial to him, within the permission, after all, Fang Yun is Wenxing longjue.

Ye Hongyu escorted Fang Yun away and went out of Zhilei mountain. Ye Hongyu said, "I will go to the place you give to find the holy air group. I only leave ten groups, and the rest is for you to cast the ninth Wentai. If there is any surplus, you and I will share it equally."

"Thank you, Mr. Hongyu!" Fang Yun made a sincere bow. Night Hongyu helped himself, which was a great sacrifice to slow down his holy way and reduce his viability.

Ye Hongyu just smiled faintly and said, "do what you can. These holy Qi are the ninth Wentai for you and only a few days for me. You know, the Terran family is not only the Zong family and the Lei family."

With that, ye Hongyu entered Zhilei mountain again.

Fang Yun looked around and found a safe place to hide. Then he cast the ninth Wentai with more than 300 holy air masses.

After 97 layers are cast, only a quarter of the 98th layer can be cast.

So many holy air masses can't be cast to the ninth floor. Fang Yun is not angry, but shows an expression that he knew it would be like this.

"No wonder no one of the Terrans has been able to cast the ninth Wentai for so many years!" Fang Yun was cruel and had to cast it.

Fang Yun studied for some time and returned to the entrance of Zhilei mountain again. Ye Hongyu was already waiting.

This time, ye Hongyu looked happy, and Fang Yun also looked happy when he saw Ye Hongyu behind him.

Behind Ye Hongyu, there was a spirit skeleton of an ancient demon giant thirty feet high!

Different from the human demon man's spirit skeleton with only bones, this ancient demon is a bronze giant. The bronze body on his body is just shrunk and slightly shriveled.

The more complete the spirit skeleton is, the stronger the strength is. Moreover, the ancient demon spirit skeleton has always been better than the demon man spirit skeleton at the same level.

Moreover, this is not an ordinary spirit skeleton, but a thunder skeleton and war skeleton that Fang Yun is looking for!

However, the thunder bone war skeleton is too old, and its breath stays at the level of four environments, which is slightly weaker than that of Wenzong or big Khan. However, due to its complete body and thunder bone war skeleton, it is difficult for Wenzong or big Khan to destroy its body. It is not too much to say that it is a relatively bulky five environment spirit skeleton.

Ye Hongyu said, "with this complete ancient demon spirit skeleton, plus the complete human spirit skeleton and two broken spirit skeletons, you can protect yourself even in the face of a big Khan."

Fang Yun greeted him with a smile and said, "thank you very much. Mr. Hongyu has found this spirit skeleton, which is very helpful to our dragon family. I thank you in the body of Wenxing longjue. However, don't spread it."

When Fang Yun finished, he reached out to Ye Hongyu's eyebrows and flew into them.

Ye Hongyu was stunned. Unexpectedly, it involved several big secrets that only the dragon family knew. It was of great help to Wenzong and even literary giants, and its value was far more than a four realm spirit skeleton.

"And these sacred air masses!"

Then he saw the holy air gushing out like a fountain.

Fang Yun swept his eyes and realized that there were 724 regiments.

"Enough?" asked Ye Hongyu.

Fang Yun sighed helplessly, shook his head and said, "absolutely not enough, at least a thousand regiments!"

Ye Hongyu frowned and asked, "only the holy Qi of more than 1000 regiments can condense the ninth Wentai. Once it condenses, you must be careful. After you accumulate enough holy Qi, you must go to the ancient demon's blood tomb cemetery or fengcranial mountain, and be sure to be in a safe place."

Fang Yunshen thought so and said, "I didn't think of this before. Now when I think about it, I really have to be careful."

"Time is pressing in the holy burial valley. I'll go back to Zhilei mountain. After a few months, the holy burial Valley changes frequently. Maybe I'll see you again. Take care!"

"Take care!"

Fang Yun watched Ye Hongyu disappear into the vast thunder and controlled the whole four spirit skeletons to fly to Fengtou mountain.

Returning to the depths of Fengtou mountain, Fang Yun returned the ten mountain cores to the mountain spirit with a heavy heart. When the mountain spirit learned that they had died at the hands of Thunder Dragon, he did not blame Fang Yun, because for the mountain spirit, war death is a noble destination.

Fang Yun stayed in Fengtou mountain and continued to cast the ninth Wentai. This time, it was finally cast to the 99th floor, but it was still half done in the end.

Fang Yun was relieved because he had at least an accurate target. Next, he only needed to find another 1200 regiments to form.

Fang Yun waited in Fengtou mountain for a day. No other ancient demons entered the mountain, and the Holy Spirit of the mountain had no redundant holy air mass. He had to leave Fengtou mountain with four spiritual skeletons and fly to the blood Tomb of the ancient demons.

With these spirit skeletons, although it is not suitable to enter the blood tomb cemetery, you can explore the dangerous or fierce edges and slowly find the holy air mass along the way.

On the first day of leaving the blood tomb cemetery, Fang Yun met a big demon king in four areas. The two sides fought for a moment and found that no one could do anything. The big demon king took the initiative to leave.

The next day, he met a barbarian in the three realms. The barbarian turned around and ran away. How could Fang Yun stop and immediately pursue and kill. After a while, it was difficult to catch up, so he continued to look for the holy Qi group.

In the next few days, Fang Yun, relying on the topographic maps of the three ethnic groups, frantically looked for the holy air mass. Along the way, he met many outsiders, evil spirits or Holy Spirits of all ethnic groups. With four spirit bones, he killed 16 evil spirits all the way, and the black marks and red eyes absorbed by his eyes increased again. Also encountered too powerful evil spirits and had to escape.

Fang Yun also met an emperor. Fortunately, a fish demon in the South China Sea dared not kill Wenxing longjue after all. He saluted Fang Yun and left.

With the passage of time, there are more and more holy air masses in Fang Yunwen palace, but many places have been searched by outsiders. If you want to get more holy air masses, you can only go to the depths of the fierce ground. Fang Yun can't enter. Even if there are three ethnic topographic maps, the growth rate of holy air masses begins to slow down.

Twelve days later, there was still more than 400 holy air mass left before the ninth Wentai was cast.

While Fang Yun was thinking about how to quickly find the holy air mass, the earth shook, and a light golden air column rushed straight to the sky in the southeast, far away from Wanshan.

"The Dragon turned over and the treasure land was born?" Fang Yun looked at the distance with burning eyes.

It's disgusting to look for holy air these days.
