When Wu Hui arrived at the Treasure Pavilion, he did not expect to encounter a stone that contained a Strength of Void.

Strength of Void was the source of all power, and it had a use and ability that ordinary people could not even imagine.

Wu Hui had already obtained a few External Strength s, some of them were indestructible, some of them were indestructible, and some were yin and yang power. These External Strength all possess incredible abilities.

As the source of all energy, Strength of Void was even more heaven-defying. If the Strength of Void was completely grasped and a true ethereal physique was condensed, then it would be able to reach the legendary Lord of All Things and be the sage of heaven and earth.

It could be said that to Wu Hui, this piece of black stone with a Strength of Void was as important as a Five Elements Pearl.

"Oh? Senior, junior only needs to tell you the history of this black stone and you will be able to obtain one million Spirit Coin s? " Wu Hui's face revealed surprise, as though he was extremely interested in this million Spirit Coin.

"Hehe, not bad, if you can even tell me where it came from, you will get one million Spirit Coin." Dozens of almighty people had seen this black boulder, but they did not know its origin. Amongst them, there was no lack of Martial Sovereign Expert, although the young man in front of them had good talent, he was still too young, how could he possibly have any knowledge of it.

"Senior, would you like me to take a closer look?" Wu Hui bowed and said, with a passionate look, he looked like he was opening his eyes wide to money.

"Hur hur, just watch and see." The Martial Monarch booth owner casually threw the black stone at Wu Hui, not afraid that Wu Hui would snatch it away.

At this moment, Wu Hui really had the thought of running away after taking it with him. It was probably because the owner of the Martial Monarch didn't know the value of the black stone, otherwise, he wouldn't have brought it out.

Wu Hui picked up the stone, his body slightly stiff. A trace of Strength of Void flashed past his eyes, but he quickly returned to normal, he raised up the black stone and placed it in front of his eyes to carefully inspect it. Sometimes he nodded his head, sometimes he shook his head, sometimes he looked confused, and sometimes he was happy. In the end, Wu Hui returned the black stone to the Martial Monarch vendor, his face revealing a warm smile, "Senior, do you want to buy this black stone?"

"What?" The Martial Monarch's booth owner was startled, he didn't understand why the other party would ask such a question. The stone's origin was extraordinary, was it possible that there was more to it?

If you want to buy it, then it will be even more expensive. My hometown is filled with these black stones, I did not expect them to be so valuable. If senior wants them, I can sell them to senior. Wu Hui's eyes lit up, his entire being filled with greed.

"Junior, you dare to make fun of this old man. This black crystal was obtained from the depths of Endless Void Sea s in other realms by Yan Clan s. How could your hometown possibly have it?" The owner of the Martial Monarch was furious. With the rise of his aura, the pressure from the Expert of Martial Monarch was released, pressing down on Wu Hui.

Wu Hui's body staggered a few steps backwards, his face revealing a hint of fear, but his heart remembered this place, Endless Void Sea.

Martial Monarch's aura was not small, the entire fourth floor of Treasure Pavilion sensed it, and gathered around, looking at the scene in surprise.

"Eh, why is the usually good-natured Flame Crystal Pill Imperial so angry? Who dares to provoke him today?"

"It should be that azure-robed youth. He seems to have played with the Flame Crystal Pill Imperial."

"How awesome!" "Tell me what kind of entertainment it is."

"I'm not sure either. The Flame Crystal Pill Imperial seemed to indicate where the black stone came from."

Everyone was discussing amongst themselves. At this moment, the Flame Crystal realised that it had blurted out the origin of the black stone. It could not help but blush and become even more angry.

"Junior, since you said that there are plenty of these stones in your hometown, take one out and sell it to this old man. This old man will use ten million, no, one hundred million Spirit Coin to buy them. Flame Crystal's eyes were filled with rage, she stared straight at Wu Hui, and seemed like she was about to attack.

Yan Xundao, who was beside Wu Hui, frowned. He also did not know what exactly this black boulder was, nor did he expect Wu Hui to actually spout such nonsense, wanting to take a step forward and resolve the dispute. In the end, Yan Xundao was Yan Xiangtian's clone, so his words had some weight.

"Brother Yan, let this matter be settled by brother." Wu Hui pulled Yan Xundao, whose relationship with Yan Xiangtian was after all rather complicated, and it would not be easy to reveal his identity.

Wu Hui walked in front of Yan Jing, bowed once more, and said, "Has Senior Yan's words ever been true? If I really took out this black stone, would senior really exchange it for a hundred million Spirit Coin? "

"Of course, if you have one of these stones, I will take one hundred million Spirit Coin, and if you have two of these, I will take two hundred million Spirit Coin, and you can have as many as you have, I will take as many as you want, but I must also remind you that these stones contain some kind of mysterious energy, you don't have to think about using these broken stones to impersonate them, this old man is not blind." He did not believe that the other party would actually be able to take out such a stone. This stone was obtained by the Yan Clan from the depths of Endless Void Sea, which was a dangerous place in the Outer Realm, with great difficulty. If there was such a thing, it would be extremely strange.

"Alright, I just happened to have a few on me. Senior, look carefully and see if it's a rock like you." Wu Hui said as he nodded his head. With a flick of his wrist, he took out three black stones and placed them on the table in front of the Flame Crystal.

"Junior, I must warn you. If you dare to tease me again, I …" At this point, the Flame Crystal did not speak any further. At this moment, he had already touched a black rock and a hint of shock appeared on his face.

The Martial Monarch Spiritual Sense inspected the inside of the black stone. Gradually, the expression on the black stone changed from shock to dull. In the end, it held the stone in its hand and did not say anything for a long time.

"Senior, is there any difference between my stone and yours?" Wu Hui's expression was calm as he asked indifferently.

The flame crystals seemed to have thought of something and hurriedly picked up the other two black stones. The Spiritual Sense examined them for a while, its face revealing a trace of dejection as it mumbled, "Could it be that there are really that many black stones?"

Wu Hui's mouth curved into a faint smile. He had finally gotten his hands on such a great opportunity.

What Wu Hui wanted was not the black stone, but the real Strength of Void inside. The moment Wu Hui came into contact with the black stone, he had already absorbed the Strength of Void's energy into his own body. Wu Hui's physique was empty, it was an existence that was more suited to the Strength of Void than the black stone in the first place. After absorbing the Strength of Void into his body, Wu Hui produced another strand of Strength of Void and injected it into the black stone. It looked like there was no difference, but the nature of the stone had changed. The Strength of Void before was an existence that existed between heaven and earth forever, and the Strength of Void after that was the Strength of Void that was activated by Wu Hui. It was like the difference between natural and human beings. Only the natural Strength of Void s were what Wu Hui truly needed.

After that, Wu Hui split out the three threads of Strength of Void and formed the three black stones. Not to mention that the flame crystal was at the Martial Monarch level, even the average Martial Saint would find it difficult to detect the difference between the two.

Strength of Void s were originally a power that only the top experts of the Martial Saint could touch. Only those who had reached the peak of the Martial Saint could experience the power of Strength of Void.

"Senior, these three stones are about the same as your black stones. If junior is truly mistaken, junior is willing to apologize and compensate senior." Wu Hui walked in front of the flame crystal body, bowed once more, and said extremely politely.

"That's right, your three stones are exactly the same as mine." The expression on his face was extremely complicated.

The surrounding crowd immediately burst into an uproar when they heard this. They all knew that the black stone was the only one in the Treasure Pavilion that was being treated as a treasure by the Flame Crystal. Although they did not know the specific effects of the black stone, it was something that the Yan Clan Supreme Elder had gone through countless difficulties to obtain, so it must be extremely extraordinary.

"Senior, since what I said was true, can you return these three stones to me? After all, these are things from my hometown. When I train here, I just want to leave a thought." Wu Hui said as he reached out his hand.

"No, no! I've already said it before, if you want to buy these stones, you can just give these three to me. " As he said that, two kinds of storage card appeared in Yan Jing's hands and he passed them over to Wu Hui. "These are the two hundred million Spirit Coin, I'll give you the remaining one hundred million when you come to Treasure Pavilion again tomorrow."

This time, it was not an act. Originally, the moment he had obtained the Strength of Void, he had gained an enormous advantage. If he were to once again use this casually made black stone to exchange for three hundred million Spirit Coin, Wu Hui would feel very bad, but seeing the Flame Crystal's appearance, he truly could not refuse.

"All right. Senior Yan, junior will be taking his leave. " In the end, Wu Hui took the storage card and left with Yan Xundao. Although there were still good things in the upper levels of Treasure Pavilion, but even the best of things were not as good as this Strength of Void.

"Wu Hui, what kind of stone is this?" After exiting the Treasure Pavilion, Yan Xundao suddenly asked. He still had not figured out the reason behind Wu Hui taking out three black stones like that, since the black stones were taken from the Outer Realm, they must be extremely rare, and how did Wu Hui obtain them?

"There is my Dao within this stone." When Wu Hui finished speaking up to this point, he did not continue speaking. Yan Xundao's eyes lit up and did not ask any further questions, but Yan Xundao knew that Wu Hui's goal was not Martial Saint, but an even higher level.

Wu Hui and Yan Xundao returned to the Yan Clan Palace and did not go out ever again. Even on the second day, Wu Hui did not go to the Treasure Pavilion to retrieve the one hundred million Spirit Coin, but stayed in his room to comprehend the sliver of Strength of Void. In the blink of an eye, three days had passed.
