The cost of materials required to refine a treasure that can control the flow of time is extremely expensive. This is because this material has to withstand the deficit of time inside and outside the space. Ordinary materials simply cannot withstand this kind of impact that violates the laws of heaven and earth, and may be destroyed by this force in an instant.

And refining such a treasure is not comparable to refining an ordinary space ring at all! refining a space ring, as long as the comprehension of the laws of space reaches the realm of small perfection, that is, a cultivator who has reached the realm of heavenly gods, can easily do it. But this kind of refined space ring is just a simple item storage space, and it can't even store energy bodies, let alone store all kinds of creatures and other things!

The space that can store living beings and energy bodies is already regarded as a world, and a cultivator who can open up a world is definitely a master of the two laws of space and time who have reached the realm of Great Perfection. The cultivators who have opened up the great world are all realm master-level powerhouses.

The current Xia Yan is impossible to open up a world. Even if you open up a space for reading, it is still an incomplete space, which can collapse and destroy at any time, and it cannot carry any energy. The Tower of Time, on the other hand, can not only carry energy, allow Xia Yan to enter, but also change the flow rate of time in it. The value of this treasure and its preciousness can be imagined!

In fact, if Xia Yan's Tower of Time had not been damaged, it would have been impossible for the Lord of the Xuanshangyu Hall to give it to Xia Yan. It's just that because the Tower of Time has been damaged and cannot be repaired, the Xuanshang Yu Hall Lord has also tried to repair the Tower of Time in many ways, but they have not succeeded, and even the Realm Lord Jiang Yun has nothing to do about it.

Therefore, the Lord of the Xuanshang Yu Hall gave this Tower of Time to Xia Yan, and he was also a little reluctant at that time!

"I will work hard to cultivate and strive to reach the core hall master level creation as soon as possible!" Xia Yan said to Xuan Shangyu with a calm face and a resolute voice.

Looking at Xia Yan, Xuan Shangyu smiled and nodded with satisfaction.

Once Xia Yan reaches the core hall master level creation, then the Lang Evil Realm will have two core hall master level creations, and in many big worlds, the power will of course increase a lot.

Now, even Lord Jiang Yun, the realm master, will pay special attention to Xia Yan.

In the history of the eight great worlds controlled by Jiang Yun, the cultivation speed that could be compared to Xia Yan was definitely not more than five fingers. Jiang Yun Realm Lord, of course, has to pay attention to Xia Yan. If Xia Yan can become a realm master-level powerhouse in the future, then ......

The more core hall master-level powerhouses under his command, the stronger his overall power will be.

It's like fighting for the treasures in this ruin now, Jiang Yun now has nine core hall master-level powerhouses under his command, which is much weaker than those forces that have dozens of core hall master-level powerhouses.

And it is also very difficult to cultivate a hall master-level core hall master-level powerhouse. In the past hundreds of millions of years, there are only a few core hall masters who are still alive under Jiang Yun's command, and there are only a few people in the eight great worlds!

"Boom!"

Another loud bang came out, and the space of the ancient ruins trembled slightly. Those dozens of cultivators attacked the main gate of the silver palace one after another, trying in vain to break open the main gate of the palace, but the main gate did not move at all, and there was no sign of opening it at all.

Most of the realm master-level powerhouses just looked at it coldly and didn't go up to get involved. They weren't worried, even if the palace door was really broken, they would have enough time to enter it and look for an opportunity.

"Damn!"

"How strong is this damn gate, and what kind of material are these things made of?"

"Lord of the Realm, I don't think we can open the gate with just us!"

Among those dozens of cultivators, only one cultivator was at the realm master level. The others are all at the core hall master level, and they are obviously all under the command of the realm lord powerhouse.

The power of this realm lord powerhouse is much greater than that of Jiang Yun realm lord.

Xia Yan saw that this realm master-level powerhouse was wearing a golden robe, his face was cold, and his bright eyes flashed from time to time.

Hearing what the cultivator under his command said, this realm master-level powerhouse raised his arm slightly, signaling the core hall master-level powerhouses under his command to stop temporarily.

"The material of this palace is indeed very strong, and the material is much stronger than the ore we use to refine the artifact. But if that's it, it won't stop us!" the realm lord in the golden robe shook his head and said slowly, "What really stops us is not the material, but the formation carved on top of this palace. ”

"Haha...... Chen Wen, you're right! The reason why this palace is so strong and indestructible is because of the formation carved on it, and the name of this formation is called the Nine Heavens Mixed Yuan Secret Pattern!"

At this time, another realm master-level powerhouse laughed out loud and said to the Chen Wen realm lord in front of the palace. The realm lord powerhouse wearing a golden robe, his name is Chen Wen.

"What, you said it's the Nine Heavens Mixed Yuan Secret Pattern?" Chen Wen was slightly surprised and looked at the cultivator who spoke!

Although he had already seen that there was a large array of patterns in this palace, he didn't know that this pattern turned out to be the Nine Heavens Mixed Yuan Secret Pattern. Chen Wenjie's brows couldn't help but wrinkle deeply at this time.

"Exactly!"

"This kind of pattern has long been lost, and only some of the crystals handed down from ancient times have some pieces of record! If you want to forcibly break through this powerful defensive pattern, I'm afraid only a godlord-level powerhouse can do it!" The realm lord powerhouse who was talking to Chen Wen stroked his beard and said with the corners of his eyes narrowed.

"It turned out to be the Nine Heavens Mixed Yuan Secret Pattern, no wonder it was so powerful!" Jiang Yun Realm Lord said in a low voice.

Even he didn't see what kind of lines were on this palace.

"It's troublesome now, the defense of this pattern is very powerful, if you want to forcibly break it, I'm afraid you really need the Divine Master!" Jiang Yun shook his head.

"Lord Realm, can't all of us break through this Nine Heavens Mixed Yuan Secret Pattern with the strength of all of us?"

"If it's really the Nine Heavens Mixed Yuan Secret Pattern, then even if we have several times more people, we won't be able to break it!" Jiang Yun shook his head, "Thirty million years ago, I saw a ban composed of the Nine Heavens Mixed Yuan Secret Pattern, and that time, there were hundreds of realm master-level powerhouses and thousands of core hall master-level powerhouses, but they all failed to break it in the end!"

"Hmm, has that prohibition never been opened?" Xia Yan interjected.

"It was opened, but it was only successfully opened by a god-level powerhouse! It was also a secret treasure, and finally the god-level powerhouse made a move to break the ban, and of course the treasures were also owned by the god-level powerhouse. Jiang Yun looked at Xia Yan, "It's ridiculous that all of us didn't see the true face of a god-level powerhouse in the end!"

"How can this be?" Xia Yan's face changed, and he couldn't help but say.

"Hehe, Xia Yan, you haven't met a god-level powerhouse, so you can't understand that feeling at all. Even if a god-level powerhouse stands in front of you, you can't see his face clearly, you can only see a cloud of energy and a cloud of law exist!" Jiang Yun sighed slightly.

"The realm lord in the blue robe, named Li Yuankui, has a wide range of knowledge. Don't look at the fact that he doesn't even have a core hall master by his side, that's because he hasn't opened up the big world at all. In fact, before I reached the Realm Lord level, he Li Yuankui was already a Realm Lord-level powerhouse!" Jiang Yun said.

The person he was referring to was the realm lord powerhouse who spoke to Chen Wen! Li Yuankui!

"Then what should we do? Do we just wait until the Divine Lord level powerhouse hears the news, and then watch the God Lord powerhouse break open this palace and take away the treasures in it?" Xuan Shangyu widened his eyes slightly.

......................................................

"Huh...... Since it is the Nine Heavens Mixed Yuan Secret Pattern, then we have almost no chance to break it, Li Yuankui, do you know that this is the Nine Heavens Mixed Yuan Secret Pattern, and you are still wasting time here?" Chen Wen looked at Li Yuankui, sneered, and said with his hands behind his back.

"Actually, this Nine Heavens Mixed Yuan Secret Pattern is not something that only a Divine Master-level powerhouse can break through! I know that there is one person who can break this pattern!" Li Yuankui said indifferently.

"What?" Chen Wen was surprised!

The other cultivators also looked at Li Yuankui in surprise. Just now Li Yuankui said that the big array on this palace was the Nine Heavens Mixed Yuan Secret Pattern, and everyone was a little disappointed in their hearts, but Li Yuankui suddenly said so.

"A friend of mine happens to be able to break through this pattern, hehe, his research on the Great Array is not comparable to us!" Li Yuankui said with a smile, "Don't worry, you will see this friend of mine in a while, he has already arrived in this ancient ruins at this time, and it won't take long to reach here!"

Li Yuankui said, looking behind him.

The other cultivators also took advantage of the situation, and everyone wanted to see who the cultivator Li Yuankui said could break through the secret pattern of the Nine Heavens Mixed Yuan!

Sou!

A figure, as fast as lightning, was close in an instant. Xia Yan saw that the person who came was wearing a gray robe, his face felt very clean, and the corners of his mouth were slightly raised.

"Li Yuankui!" After the cultivator paused, his eyes swept away, and he saw Li Yuankui in the crowd, and shouted with a smile.

"Xu Mingfang!" Li Yuankui also shouted with a smile.

"Xu Mingfang, could it be that guy from the Great World?" Jiang Yun looked at the person who came and muttered in a low voice, "This guy has already reached the Realm Lord level? Some time ago, wasn't he still the Core Hall Master?

Jiang Yun exhaled.

"Xia Yan, the Great World has a very long history, with a history of more than 600 million years!"
