Xu Yang used mysterious power to detect the golden pad. He discovered that the golden pad was very special, neither gold nor jade, but the structure was very dense and hard, and at least it could withstand the full-strength attack of the powerful Xuanjun.

Xu Yang took a lot of effort to detect the inside of the pad with his mysterious power. In this pad, he felt the rich fluctuations of the extremely mysterious energy of the earth.

"Is such a strange treasure just what the bronze brick says, contains the most energy-filled thing?" Xu Yang frowned and took out the bronze plate from the storage ring.

"What's the matter?" asked a line of words automatically appeared on the bronze plate.

"Look at what this is, is it a treasure containing the most energy?" Xu Yang asked with the golden pad to the bronze board.

The bronze plate was spelling with crackling words: "Xiao Xuanzi, do you think you can meet one wherever you go?"

"So... this pad is useless?" Xu Yang said with some disappointment.

"It's almost the same, you can leave it to me to eat." The bronze plate crackled and spelled, with a taste of no other than me.

"Hmm?" Xu Yang felt something was wrong. This bronze plate has such a tricky appetite. There are few in the world. Not to mention the eighth-grade treasure materials, even the holy materials are not very good. How can it be attracted to this golden pad?

This can only explain one problem. This pad is definitely not an ordinary treasure, at least it is a thing of the level of holy material.

"Tell me, what is this," Xu Yang said, "Otherwise, you won't be able to eat any treasures in the future, let alone holy materials."

"Xiao Xuanzi, how many times did I help you? You can't treat me like this!" Bronze plate typing.

"But you just tried to deceive me, and I should do this to you," Xu Yang snorted. "Give you a chance to make up for your merits and tell me the purpose of this thing. If I can't use it, I can consider eating it for you."

The bronze plate was excited and typed: "Although this thing is not a treasure with extreme energy, it is also related to extreme energy. It must be near a certain kind of earth and extreme energy. It has been displayed for a long time, resulting in the material being converted by the earth and extreme energy, becoming stronger than gold and stone. In fact, this thing was just a clay board."

Xu Yang was happy: "So, there is a treasure containing the most energy of the earth in this central tomb?"

"Wrong!" The bronze plate denied mercilessly, "In this tomb, there are no earth treasures, let alone extreme energy. I can detect the fluctuations of extreme energy."

Xu Yang was a little disappointed. He picked up the golden pad and stood up.

"Hey, hey!" The bronze plate spelled and reminded Xu Yang.

Xu Yang threw the golden pad to the bronze pad, but he didn't know what method the latter used. As soon as the golden pad touched it, it disappeared.

"Xiao Xuanzi, don't be disappointed. To thank you for finding such a good thing for me to eat, I will give you a free clue?"

"What clue?" Xu Yang looked at the bronze plate.

"Please pay attention to this coffin board. Have you found anything?" said the bronze board.

Xu Yang was slightly stunned. He had been paying attention to the inside of the white stone coffin, and did not look closely at the coffin lid. At this moment, following the prompt from the bronze plate, Xu Yang brushed off the coffin lid and found that there was a simple pattern engraved on it.

There are six small black dots evenly distributed above a large arc. Each small black dot has a connection line, forming a very regular hexagram array diagram.

In the center of the hexagram, a large black dot is in the eye.

"What does this picture mean?" Xu Yang asked.

"How do I know? But it's always related to this ancient tomb," said the bronze plate. "You try to use the power of the mind to explore."

Xu Yang held the mentality of being a living horse and gently tapped the middle of his eyebrows. A blue light shot out and projected onto the array diagram.

"It seems that there is no effect..." Xu Yang swept across the formation diagram one by one with his mental power, and said in disappointment.

At this moment, Xu Yang's eyebrows swept across the small black dot in the upper right corner of the picture. Suddenly, his mental power was quickly consumed, and he continued to pour into the small black dots.

With the injected mental power, the small black dot slowly magnified in front of Xu Yang's eyes.

"There is a change!" After being surprised, Xu Yang suppressed his excitement, urged his mind and injected it into the pattern.

Finally, the small black dot in the upper right corner absorbed enough mental power, and quickly expanded, and soon turned into an illusory pattern that was one foot square, with lines interlaced horizontally and vertically.

"What is this..." Xu Yang frowned.

In the pattern on the coffin lid, there are six points at the corners of the hexagram, plus a large dot in the central area, and there are seven black dots in total. Among these black dots, only one black dot in the upper right corner has an induction of Xu Yang's mental power. After amplification, there is such a horizontal and vertical figure.

The bronze board honestly spelled: "It depends on you to think about it yourself, this is the only clue about the extreme energy."

Xu Yang sat cross-legged on the ground, frowned and thought hard, and the lines that interlaced horizontally and vertically changed rapidly in his mind, deducing one figure after another.

This calculation took three days. During this period, Xu Yang tried all the methods, even using the methods of running script and other methods. Unfortunately, he was still clueless.

"It seems that it's not possible. Let's leave and move towards the maze in the northeast direction. The senior brothers of the Emperor Sect should be there." Xu Yang shook his head and said.

"This may be because the opportunity has not come, and it cannot be forced." Bronze plate typing comforted.

Xu Yang smiled bitterly, calmed down his mood, and said to the bronze plate: "Did you see the blue pearl in the white stone coffin? What is this, do you know?"

The bronze plate did not keep it in hiding this time and replied happily: "This is the soul crystal core. In the wilderness era, some races will have these things to appear after death, which contain their residual souls. Moreover, the stronger it is during the lifetime, the stronger the soul crystal core left after death. Such a blue soul crystal core is definitely left by a magic elephant-level master. Unfortunately, it is not very useful to you."

The only purpose of this soul crystal core containing residual soul is to devour the practitioners of the Xuan Dynasty and strengthen their own mental power. However, this will lead to the mental power of the practitioners of the Xuan Dynasty and impure, which will be more difficult when breaking through the realm, and may even trigger the inner demon disaster.

Xu Yang once used Zhenxuan Tower to devour the life essence of the dead, which contained the power of residual souls. As a result, when he became Xuanjun, he encountered the inner demon disaster and almost died. Since then, Xu Yang has decided that he would no longer use the devouring power of Zhenxuan Tower until he had no choice.
