His gaze stayed on the bone fragment, and Mo Zhiyao's brows wrinkled slightly imperceptibly. After some observation, the latter did not see any difference in the bone fragment, and even if it was a spiritual perception, there was no fluctuation. No matter how you look at it, it's an extremely ordinary piece of broken bone. And I'm not sure if it's a human or a monster.

His eyes moved slightly, and Mo Zhiyao also glanced at Ge Shu Hongyan and the others beside him. For this way of Taobao in the sand, Mo Zhiyao thinks that he is far inferior to others.

But what puzzled Mo Zhiyao was that at this moment, although the three of them also noticed that Mo Zhiyao was interested in the bone fragment, they didn't see any clues after some observation. Therefore, the three of them also looked at Mo Zhiyao with the same doubtful eyes.

Seeing the three of them react like this, Mo Zhiyao spread his hands helplessly. But at this moment, the solemn voice of the phoenix sounded in my heart again.

"Master, no matter what the cost, you have to get this bone fragment in your hands. ”

"What is the secret of this bone fragment?" Hearing Shen Feng's solemn opening, Mo Zhiyao's heart suddenly tightened. To make the phoenix speak like this, this bone fragment is definitely not an ordinary thing.

"I saw this bone fragment when I followed the old master, I will never admit it, although I don't know what the specific function is, but I am sure that it should be related to the demon mound. A slightly muffled voice sounded, causing Mo Zhiyao's pupils to suddenly constrict.

"Demon Mound!" The name spit out from the mouth of the Stygian Phoenix made Mo Zhiyao's eyes directly glow with a look of horror that could not be concealed, and then Mo Zhiyao hurriedly lowered his eyes to cover the horror in it.

Regarding the demon mound, Mo Zhiyao once knew something about the ancient books collected by Nanyuan and Zuo Changfeng's mouth. In the Ten Thousand Demon Domain, there is one of the most mysterious and ancient existences, which is the holy place in the hearts of all demon beasts, and it is also a treasure place that all monks in the Southern Regions want to enter the most. And that place is the Demon Mound.

According to legend, the demon mound is a place left over from ancient times. Among them, there are countless bones of peerless demons who have reached the eightfold level after their fall, and even legends say that there are bones of ancient divine beasts.

The ancient divine beasts, even if they fell, there were remnants of the power of the bloodline in the bones, and the power of the bloodline already had a huge allure enough to kill the current demon beasts. For example, the Heavenly Ghost Phoenix Clan, which is the most powerful in the Demon Beast Realm today, is because of the ancient phoenix bloodline in its body, so it stands at the top of the food chain and overlooks all other demon beast races.

And if you can find the bones of the ancient divine beasts in that demon mound and get the power of the bloodline in it, it will make some demon beasts with low bloodline level soar into the sky, and it is not an exaggeration to say that it is a fish leaping over the dragon gate!

Changing the bloodline and being reborn, no demon beast can resist such temptation.

Moreover, not to mention the somewhat ethereal bones of ancient divine beasts, even if it is the bones of the great demons of the eightfold realm, they are also rare treasures. Being able to cultivate to the eightfold realm, the bodies of those demon beasts also have the power of the bloodline of ancient divine beasts, but in comparison, they are much thinner.

But no matter how thin it is, it is also the bloodline of the divine beast, and if you get it, it also has the anti-heaven effect of changing the bloodline of the demon beast itself!

Therefore, all the demon beasts in the entire human world are crazy and want to enter the demon mound, looking for the slightest opportunity to make themselves prosperous. Once you get the bloodline of the divine beast, it will be a real salted fish turning over and becoming a transcendent existence at the top of the demon beast world.

As for the demon mound, the human monks were also very red-eyed. Although human cultivators cannot change the power of their own bloodline through the bloodline of the divine beast, the bloodline of the divine beast can be used to improve the grade of the spirit treasure and refine various anti-heaven pills.

Just like the Dark Phoenix Breaking Dome Seal in Mo Zhiyao's hand, if he can get the power of the ancient phoenix, he can be promoted to a Chaos level spirit treasure!

In fact, not only the Stygian Phoenix and the Evil Jiao, but even Xiao Qiong and the Resentful Cang, and even the Nine Colors, can use the power of the bloodline of the divine beast to improve their own grade! After all, Lingbao is different from human monks. Because of the ancient nature of their own bloodlines, human monks cannot fuse the power of the bloodlines of other types of life, but Lingbao is not subject to this restriction.

Therefore, for that demon mound, whether it is a demon beast or a human monk, they are quite hot-eyed, every time the demon mound is opened, it will set off a storm in the southern region, and even eight major cultivators will make a move and enter the demon mound to snatch it.

However, the demon mound will only be opened once every hundred years, and the opening time of each time is only half a year. After half a year, it will forcibly squeeze out the monks and monsters in it, and then disappear, so that no one can find it. It will only be a hundred years before it will reappear.

However, the location of the demon mound every time it appears is fixed, and that is in the Ten Thousand Demon Domain.

For the Ten Thousand Demon Domain, Mo Zhiyao now has a lot of understanding, and it can be said that it is the most dangerous place in the entire Southern Domain.

In the Ten Thousand Demon Domain, the weather is bad, the poisonous miasma is pervasive, and there are even more fierce beasts among them. And in the deepest part of the Ten Thousand Demon Domain, there are many great demons who have reached the peak of their cultivation and even the eightfold void breaking realm.

Perhaps due to nature, the demon beasts in the Ten Thousand Demon Domain are more bloodthirsty and violent than the ordinary demon beasts in the outside world, even if it is a human body's transformation overhaul, if it is not necessary, it will not easily get involved in it.

And this was also one of the reasons why Zuo Changfeng heard that the blood jade spider was actually in the Ten Thousand Demon Domain, and his face was quite ugly. After all, Mo Zhiyao and Ge Shu Hongyan at that time were just in the realm of Hedao. The cultivation of that realm, entering the Ten Thousand Demon Domain, can be said to be more auspicious than lucky.

However, fortunately, according to the clues given by Mo Zhiyao, the location of the blood jade spider is the edge of the Ten Thousand Demon Domain, and it doesn't need to go too deep, so Zuo Changfeng will agree to let Mo Zhiyao accompany Brother Shu Hongyan and the two to go together. Otherwise, Zuo Changfeng would rather leave everything aside and go in person than let the two little guys go by themselves.

"Whew-" slowly exhaled a long breath, and Mo Zhiyao's dark eyes used a touch of heat that others had not noticed. Since that bone fragment is related to the demon mound, then as the phoenix said, no matter what the price, you must get it in your hands.

Mo Zhiyao's gaze stayed on the bone fragment for a moment, then turned away, and then made a look of interest in other things, and finally, he picked up the bone fragment seemingly casually.

The bone fragment was not transmitted, and no abnormal fluctuations were transmitted, no matter how Mo Zhiyao probed and perceived, under his determination, it was just the most ordinary bone fragment.

Rubbing his fingers on the bone fragment, feeling the roughness on it, Mo Zhiyao's psychology also felt extremely incredible. No matter how much he investigated, he couldn't find anything strange about the bone fragment. If it weren't for the Stygian Phoenix's insistence, it would have been difficult for him to associate this thing with the Demon Tomb anyway.

His heart fluctuated, but the expression on his face was Gujing Wubo, and that appearance was as if he was just curious about this bone fragment. Because Mo Zhiyao knew that since the owner of this bone fragment could take it out and sell it, he would never know the true value of this bone fragment, otherwise even if he was a fool, he would not show such a treasure in front of people.

In that case, you can't show too obvious traces. The people here are all cunning people, and once they are too enthusiastic, it is difficult to guarantee that the owner will not be suspicious, so they will take back the bone fragment and no longer sell it.

Immediately, Mo Zhiyao slowly raised his head, and his eyes fell on the figure behind the counter. It was an old man who was also not young, but looking at his appearance, he was a little sloppy, but in his eyes, there was occasionally a trace of essence that made Mo Zhiyao feel palpitations.

"This old man is by no means an idle person!" A flash of horror flashed in Mo Zhiyao's eyes, although this old man did not exude any aura, but it was this seemingly ordinary ordinariness that made Mo Zhiyao feel an unspeakable sense of danger. And this feeling, he has only felt in a few people

Gathering his mind, Mo Zhiyao said with a flat face: "Old man, I don't know what kind of treasure this bone piece is?"

"I don't know!" As soon as Mo Zhiyao's voice fell, the old man immediately gave a strange answer that made him almost bite his tongue. Although I had guessed that the old man definitely didn't know the true function of this bone fragment, such a straightforward answer was too direct, right?

The corners of Mo Zhiyao's eyes twitched, and then he asked, "Then I don't know how to sell this bone piece?"

"Have you taken a fancy to this bone fragment?" the old man frowned when he heard this, and then looked at Mo Zhiyao with interest, and then said, "Do you know the origin of this thing?"

Mo Zhiyao was stunned when he heard this, even this kind of question can be asked by this old man so directly and calmly, it is really speechless.

Looking at Mo Zhiyao, who didn't speak, the old man immediately smiled strangely, he also understood that this kind of question would never be answered, and no fool would say it. After all, this kind of thing is to see the eyesight and experience.

"Five million Xuanjing. The old man's palm stretched out, and his rootless fingers shook in front of Mo Zhiyao's eyes, but the words he said made the latter's face change suddenly.

Mo Zhiyao and his party had only spent less than three million Xuanjing in this trading hall before, and this old man wanted five million for one mouth, and this price made Mo Zhiyao have the urge to slap him over.

Xuanjing, Mo Zhiyuan is not bad. But this old man was obviously killing people, which made Mo Zhiyao quite unhappy.

"So expensive?" Mo Zhiyao stretched out his hand and pressed Ziyu, which showed signs of madness, and then looked at the old man, and said in a faint voice. "Sir, if you can tell me what this bone fragment does, it makes sense. But you don't even know what this bone fragment is, isn't it too much to ask for five million Xuanjing when you open your mouth?"
