There are more than 150 people in the Beacon Mercenary Group, including more than 50 core members and more than 100 peripheral members.

The Beacon Mercenary Group lost more than 20 people in the Dawning Chamber of Commerce, and several members were killed by Mu Xian and Xiao Yuerou successively, and then the seven people who attacked the new station of Night Lightning were also killed by Mu Xian, so that the core members of the Beacon Mercenary Group were only a dozen or so left.

Among the dozen or so people, only a few of them still stayed in the Shangjing City to take care of the team's property, but most of them were concentrated in Tianling Mountain, in case someone accidentally discovered the secret of the Heavenly Demon Yuan.

With the cooperation of the Golden-winged Flame Eagle and the Bloodthirsty Dragon Python, the people of the Beacon Fire Mercenary Group on Tianling Mountain had nothing to hide, and there was almost no need for Mu Xian, Xiao Yuerou, Jiang Yuhong and Jiang Yuxin brothers and sisters to do it, and the remnants of the core members of the Beacon Fire Mercenary Group and their peripheral members became the belly of the two demon beasts.

After all the people of the Beacon Fire Mercenary Group on Tianling Mountain were eliminated, the Bloodthirsty Dragon Python and the Golden-winged Flame Eagle did not stop in the slightest, and they directly dived into the Heavenly Demon Abyss.

Mu Xian did not stop the actions of the bloodthirsty dragon python and the golden-winged flame eagle, from the mouth of the Beacon Fire Mercenary Group, he already knew the secret of the Heavenly Demon Yuan.

The reason why the Beacon Fire Mercenary Group exterminated the Night Lightning Squad and turned Tianling Mountain into a forbidden place and did not allow others to approach the Heavenly Demon Abyss at will was because they didn't want people to discover a large number of demon fruits in the Heavenly Demon Abyss.

The bloodthirsty dragon python and the golden-winged flame sculpture are demon beasts, and they naturally can't resist the temptation of the demon fruit.

By the time Mu Xian and his party slowly flew into the sky and landed in the Heavenly Demon Abyss, the bloodthirsty dragon python and the golden-winged flame eagle had already eaten their stomachs and were lying down under the sun to rest.

When Mu Xian and his party approached the bloodthirsty dragon python and the golden-winged flame eagle. They only said hello. But he didn't even bother to move.

I saw that the bodies of the bloodthirsty dragon python and the golden-winged flame eagle were all bigger. As if she was pregnant in October, Mu Xian and his party looked at each other, and finally couldn't help laughing.

The area of the Heavenly Demon Abyss was unexpectedly large, and although the bloodthirsty dragon python and the golden-winged flame eagle had eaten their full stomachs, they had only eaten less than one-tenth of the demon fruits in the Heavenly Demon Abyss.

After Mu Xian glanced at the many demon fruit trees in the Heavenly Demon Abyss, his mood became irrepressibly excited.

Because it was the late autumn season at this time, it was the time when many demon fruits were harvested, and the fruity fragrance was overflowing in the entire Heavenly Demon Abyss. There are a lot of dazzling colors, and there are countless demon fruits at a glance.

As soon as Mu Xian's mind moved, he collected all the many demon fruits into the Yanwu Hall.

Mu Xian originally wanted to collect all the many demon fruit trees in the Heavenly Demon Abyss into the Yanwu Hall, but after hesitating for a while, he did not do so, but instead accepted several extremely precious demon fruit trees in the Heavenly Demon Abyss into the Yanwu Hall, and the rest of the demon fruit trees were still resigned.

The Demon Fruit Tree must be in a place where the demonic aura is very strong to survive, and it is difficult for the Demon Fruit Tree to survive on the territory of the Terrans.

Of course, the growth environment of the demon fruit tree specially created by some large sects does not count. Therefore, even if Mu Xian collected all those demon fruit trees into the Yanwu Hall, he was not sure that they would survive. Unless he can enter the Demon Domain to practice and successfully obtain the Demon Blood Order.

"The Heavenly Demon Yuan is the territory of the human race, and it is not far from the imperial city and the capital, how can a demon fruit tree grow naturally here?" Suddenly, a doubt entered Mu Xian's mind, making Mu Xian's face stagnate.

"The name Heavenly Demon Yuan itself is also problematic, how can the territory of the human race be named after the magic character, and I don't know how long the name Heavenly Demon Yuan has existed in the history of zài. ”

Mu Xian could almost confirm that he had not seen the name Heavenly Demon Yuan in the classics of later generations.

In fact, Mu Xian not only didn't see the name Heavenly Demon Yuan, but he hadn't even heard of Tianling Mountain.

With more than 20,000 years of knowledge and accumulation, although it can save Mu Xian from many detours, he even has a feeling of control.

However, this kind of control and leadership is not a panacea, and more than 20,000 years of turmoil and development are enough to change many things, and can also make many things disappear without a trace.

In particular, many classics have been collated and compiled by the officials of previous dynasties, and the authenticity of them is also debatable, and whether the collection is complete is also a big problem.

It is precisely because of these uncertain factors that Mu Xian has to carefully screen the authenticity and reliability of the knowledge in his mind when making some decisions.

Mu Xian told Xiao Yuerou and the others the doubts in his heart, Xiao Yuerou and the others were also confused, and then several people acted separately and started a carpet search in the Heavenly Demon Abyss, wanting to see what secrets were hidden in the Heavenly Demon Abyss.

Anyway, with the bloodthirsty dragon python and the golden-winged flame eagle by their side, everyone didn't have to worry about encountering the danger of their lives.

Soon, Mu Xian knew that he was wrong, and he was very wrong.

Mu Xian and his party were divided into three groups, of which Mu Xian and Xiao Yuerou formed a separate group, while Jiang Yuhong and Jiang Yuxin, brother and sister, were combined into a group because of their limited strength.

Mu Xian and Xiao Yuerou, Jiang Yuhong, and Jiang Yuxin were separated from the brothers and sisters, and he heard Jiang Yuxin's screams.

When Mu Xian and Xiao Yuerou rushed to Jiang Yuxin's and Jiang Yuxin's brother and sister's side, they found that Jiang Yuhong had turned into an old man who looked like a tree, not only his hair had become snow-white, his face was full of wrinkles, but his entire body had also been thinned several times, as if his skin was directly attached to the bones, and he couldn't see any flesh and blood at all.

What's even more terrifying is that the vitality on Jiang Yuhong's body is passing rapidly, and it may pass away with the wind at any time.

Seeing Mu Xian and Xiao Yuerou coming, Jiang Yuxin let go of her arms hugging her brother, knelt directly in front of Mu Xian, and cried loudly begging Mu Xian to help her brother.

Mu Xian glanced at Jiang Yuhong and Jiang Yuxin's brother and sister, and then his divine thoughts spread out like a tide, searching for abnormalities around his brother and sister.

It's not that Mu Xian didn't want to ask Jiang Yuxin what happened, but he found that Jiang Yuxin was already panicked at this time, and there was no way to communicate with him normally, and Mu Xian didn't think that Jiang Yuxin knew what was going on.

After a few breaths, Mu Xian's gaze fell on a black stone nearly a hundred meters away from him.

On the one hand, because the stone was dark and shiny, and stood out against the dead grass, and on the other hand, because the stone seemed to have life. Mu Xian could feel the exuberant vitality coming from it.

What's more. Mu Xian felt that there seemed to be a looming silk thread between Jiang Yuhong and the stone. This silk thread continuously pumped the vitality in Jiang Yuhong's body into the dark stone body.

"Heavenly Demon Stone...... There is actually a Heavenly Demon Stone here?" After staring at the dark stone carefully for a while, Mu Xian couldn't help but let out an exclamation of disbelief.

The Heavenly Demon Stone is not a real stone, but an object that evolved into the demon crystal in the body after the failure of the ninth-order demon beast's tribulation, because this object is extremely like a lifeless stone, so it is considered a stone by the human race.

However, once the human race approached the Heavenly Demon Stone, then the essence blood in his body would be quickly extracted. until it becomes a dry bone.

Because the Heavenly Demon Stone is an object evolved from the demon crystal in the body of the ninth-order demon beast, and the strength of the ninth-order demon beast far exceeds that of the powerful cultivator of the human Xuan Realm, it is extremely rare among the demon clan, so the Heavenly Demon Stone is also extremely rare.

Even in the demon race, few people know the Heavenly Demon Stone, let alone the human race.

Five thousand years later, when the Terran and the Demon Race were in a big war, the Demon Race once threw a few Heavenly Demon Stones into the Terran camp, resulting in countless casualties for the Terrans, which directly led the Terrans to return with a crushing defeat in the first round of the battle with the Demon Race.

It wasn't until the Terran power studied the characteristics of the Heavenly Demon Stone that it turned disaster into blessing. The use of the Heavenly Demon Stone to improve the strength of the human race, but that was already a matter of decades after the Great War.

"Heavenly Demon Abyss...... Heavenly Demon Abyss. Could it be that the Heavenly Demon Yuan was named after the Heavenly Demon Stone?" After seeing the Heavenly Demon Stone, the doubts in Mu Xian's mind were easily solved.

The secret of the Heavenly Demon Stone was only studied by humans thousands of years later, and it was obviously not known to the human race at this time, but the evil sect of the Heavenly Demon Stone was famous.

Anyone within a hundred meters of the Heavenly Demon Stone, whether you are a demon or a human race, as long as your strength does not reach the ninth order, the essence blood and vitality in your body will be quickly absorbed until death.

If the strength is not enough, the Heavenly Demon Stone cannot be destroyed at all, and the Heavenly Demon Stone cannot be put into the space storage equipment, let alone move with the mind.

There is only one way to move the Heavenly Demon Stone, and that is to fill it with essence blood and life.

At that time, in order to throw the Heavenly Demon Stone into the camp of the Terrans, the Demon Clan sacrificed countless sixth-order demon beasts along the way, and even lost hundreds of seventh-order and eighth-order essence blood in their bodies, so they could barely carry the Heavenly Demon Stone to the territory of the Terrans.

While frantically absorbing the essence blood of the animals and plants close to it, the Heavenly Pole Stone would also continue to exude a pure and rich demonic aura.

Mu Xian knew that the many demon fruit trees in the Heavenly Demon Abyss were definitely alive because of the Heavenly Demon Stone.

"Maybe others can't do anything about you, but I have a way to clean you up. Thinking of the various methods of collecting and using the Heavenly Demon Stone that had been researched in later generations, Mu Xian's face showed an excited look.

In Mu Xian's eyes, the value of the Heavenly Demon Stone was not inferior to the Demon Blood Order.

The Demon Blood Order can store demon beast pets, which can form a deterrent effect on demon beasts, and can dramatically improve the strength of demon beast pets, but this qiē is a premise, that is, there are enough demon crystals to fill it.

In addition to the fact that the Heavenly Demon Stone cannot store demon beast pets, it has all the other functions of the Demon Blood Order, and it does not need to consume any demon crystals.

What's more, as long as Mu Xian places the Heavenly Demon Stone in his residence, he can also play the role of an automatic protector, and without his permission, even the Xuan Realm can only see the Heavenly Demon Stone and run away.

"Childe, please save my brother, my brother is dying, as long as you save my brother's life, I will make you a cow and a horse. When Mu Xian was still immersed in the huge surprise of harvesting the Heavenly Demon Stone, Jiang Yuxin's hoarse cry sounded in Mu Xian's ears, waking Mu Xian up.
