Mu Xian was surprised to find that his dantian had actually turned into two distinct parts, one of which was the surging True Yuan Force, and the other part was the Demon Yuan Force roaring and roaring.

"The nature of the True Yuan Force and the Demon Yuan Force are completely different, how can they be in the same room safe and sound?" A huge suspicion surged from Mu Xian's heart.

Soon, Mu Xian found the clue.

In the middle of the True Yuan Force and the Demon Yuan Force, there is a small red silk thread that is almost invisible, and this red line divides the True Yuan Force and the Demon Yuan Force into two camps, whether it is the True Yuan Force or the Demon Yuan Force, they can only operate in their respective camps.

"This ...... The red line is made up of the red particles in the divine blood chalcedony?" After slowly observing the red line with his divine thoughts for a while, Mu Xian's eyes suddenly widened, because he found that the red line had always exuded a rich and pure heaven and earth spiritual power, and it was this rich and pure heaven and earth spiritual power that allowed the True Yuan Force and the Demon Yuan Force to move in their respective camps obediently.

"It seems that the function of the Divine Blood Chalcedony is far more magical than I imagined, and the predecessors may not have figured out all the functions of the Divine Blood Chalcedony. After confirming that the divine blood chalcedony had been integrated with his dantian, allowing himself to have both true yuan power and demon yuan power, Mu Xian couldn't help but sigh softly.

"The problem of the identity of the demon clan is indeed a big problem, with the identity of the snow fox clan, if it is discovered by the human race, it will be absolutely a dead end, and there is no room for choice. However, as long as you can hide the demon yuan power on your body and prevent people from discovering it, the identity of your demon clan should not be exposed, right?" Mu Xian muttered a sentence in his mouth, and then his willow eyebrows lightly frowned, and several exercises to conceal the aura of the demon yuan power in his body flashed in his mind.

20,000 years later, the human race and the demon race are no longer opposed, but have become the same camp, jointly dealing with the evil demons outside the sky, in order to maximize the combat effectiveness of the alliance camp, the human race and the demon race high-level have released the ban, so that the human race and the demon clan can share the exercises.

Whether it is the human race or the demon race, they are particularly interested in the exercises of the alien race, especially some people with ulterior motives, they are worried that after the war against the demons outside the sky, the human race and the demon race will start the war again, so they all take the opportunity to desperately record and study the exercises of the alien race.

Mu Xian had the idea of learning from each other's strengths, and studied all the exercises shared by the demon clan, and integrated and improved them, including the exercises to conceal the demon power.

Mu Xian was convinced that after he hid the demon Yuan Force, unless the other party could see his bloodline at a glance, he would never be able to discover his demon clan identity.

After staying in the bathhouse for most of the day and basically adapting to the changes that had occurred in his body, Mu Xian remembered that his parents and others were still in his room.

In the next moment, as soon as Mu Xian's mind moved, the two tails behind him disappeared without a trace, and at the same time, the demon yuan power on his body was also perfectly hidden, leaving only a rich yuan force fluctuation, and it was twice as much as before.

When Mu Xian returned to the room again, Mu Yuanshan, Tang Qiluo and Mu Yuan subconsciously surrounded him, their eyes full of concern.

"Father, mother, uncle, let you worry, I have now successfully broken through the bottleneck and reached the Ning Yuan Realm. Seeing that his parents and uncle wanted to talk and stopped, Mu Xian smiled and greeted him cordially.

Mu Xian laughed, but Mu Yuanshan, Tang Qiluo and Mu Yuanshan couldn't laugh, Mu Yuanshan had been tossing in the bathhouse for most of the day just now, and the three of Mu Yuanshan had been worried about Mu Xian's house for most of the day.

Seeing that the expressions on his parents and uncle's faces were wrong, Mu Xian was stunned for a moment, and then reacted to what was going on.

"Dad, mother, uncle, you should be worried about the identity of my demon clan, you can take a look now, can you still recognize the identity of my demon clan?"

Hearing Mu Xian's words, Mu Yuanshan's three faces were full of doubts, and they subconsciously looked at Mu Xian.

The next moment, Mu Yuanshan, Tang Qiluo, and Mu Xian all widened their eyes, because they couldn't feel the slightest fluctuation of demon yuan power from Mu Xian's body.

"My mother, where is your tail, could it be that something happened, your demon pill is broken, right?" Mu Yuan was not anxious, he circled around Mu Xian, pinched Mu Xian's buttocks, and exaggeratedly exclaimed.

Mu Yuanshan and Tang Qiluo looked at Mu Xian intently, and their eyes were full of inquiring eyes.

Hearing the uncle mention his tail, he touched his buttocks with his hand, Mu Xian's face turned red, he glared at the uncle angrily, and avoided the uncle from a distance, only then did he remove the disguise and release the demon yuan force.

In the next moment, the surging demon yuan force rampaged through the house, as if the ancient desolate beast was roaring, and it was like a fierce ghost shouting, and the entire house suddenly fell into an eerie atmosphere.

Suddenly, the three people in the house, Mu Yuanshan, shivered together, and their eyes looking at Mu Xian were full of astonishment, and even with a hint of fear.

Mu Yuanshan, Tang Qiluo and Mu Yuan were not shocked to find that at this time, Mu Xian's body actually did not have any true yuan power fluctuations, only demon yuan power fluctuations, as if Mu Xian was not a human race, but a pure demon race.

With the cooperation of the demon yuanli, Mu Xian's every move was full of evil spirit, which was overwhelming and unstoppable.

Mu Xian's final choice of the exercise to conceal the demon Yuan Force is "Yuan Demon Tong", "Yuan Demon Tong" This technique is a technique researched by the human race in order to deal with the demon race, it can well disguise the true yuan force fluctuations as demon yuan force fluctuations, so that the human race master can sneak into the demon clan, thus causing a fatal blow to the demon clan.

In order to deal with the human race, the demon clan also created a technique similar to "Yuan Demon Tong", which can disguise the demon yuan force fluctuations as true yuan force fluctuations, so as to achieve the purpose of breaking the human race from within the human race.

Mu Xian felt that this kind of exercise was extremely fun, and it was also convenient for him to enter the territory of the demon clan to find some special medicinal herbs, so he carefully studied the technique of "Yuan Demon Tong", and practiced it perfectly, so it was very handy to perform it at this time.

Seeing that his parents and uncle seemed to be stunned by the Yuan Demon Tong Exercise he had performed, Mu Xian switched the exercises again, and all the Demon Yuan Force fluctuations on his body were transformed into True Yuan Force Fluctuations.

"Xian'er, this ...... What's going on, how can the True Yuan Force Fluctuations and Demon Yuan Force fluctuations on your body change at will, and it is completely impossible for people to see the flaws?" After being silent for a long time, Mu Yuanshan asked softly.

Mu Yuanshan was deeply shocked by what happened to Mu Xian, because Mu Xian's performance was beyond common sense, making him completely incomprehensible.

"Dad, you should know this matter better than me, when I was impacting the bottleneck, did you take the Divine Blood Chalcedony, and the Divine Blood Chalcedony submerged into my body?" Mu Xian hesitated for a moment, and said crisply, "After the Divine Blood Chalcedony entered my body, it directly merged with my dantian......

The origin of "Yuan Demon Tong" is too magical, and Mu Xian naturally can't say it, so on the way to the East Courtyard, Mu Xian thought of the lines and pushed all the credit to the god blood chalcedony.

After listening to Mu Xian's narration, Mu Yuanshan opened his mouth in astonishment, unable to speak for a long time.

Even Tang Qiluo and Mu Yuanfei on the side were also stunned and at a loss after hearing about the magical changes that had taken place in Mu Xian.

"Dad, I originally planned to leave the Divine Blood Chalcedony in the family, so that you and Uncle Ling and other family elders can use it when breaking through the cultivation bottleneck, but now the Divine Blood Chalcedony has inexplicably merged with my dantian, and I can't separate it, I'm really sorry. When he said this, Mu Xian was also extremely depressed, the divine blood chalcedony was fused by the dantian, and he didn't know whether it was good or bad for the time being.

"The divine blood chalcedony is originally your personal thing, not the family's, and if it's gone, it's gone. Xian'er, I want to confirm one thing with you, when you transform the True Yuan Force and the Demon Yuan Force, do you confirm that there are no flaws, and no one will see it?" Although the Divine Blood Chalcedony is a rare treasure, compared to the Divine Blood Chalcedony, Mu Yuanshan is obviously more concerned about Mu Xian's safety.

Mu Xian was stunned for a moment when he heard this, and then his heart was moved, he nodded heavily, and said confidently: "Dad, although you can rest assured, I know the situation in my body very well, unless I accidentally say it myself, no one will be able to see through the secret in my body." ”

Mu Xian's words are not exaggerated, in this era, the human race and the demon race are still in an extremely bad state of opposition, and many exercises and martial arts are not perfect enough, so few people study exercises outside their own clan, let alone exchange exercises with each other.

Hearing Mu Xian's words, Mu Yuanshan and Tang Qiluo almost swept towards Mu Xian's slightly drooping hands, and when they found that Mu Xian's hands were not clenched into fists, a stone in their hearts fell to the ground.

After confirming that Mu Xian would not reveal his identity even if he lived in the Terran Shijie, Mu Yuanshan, Tang Qiluo and Mu Yuanfei found that they were worried before, since Mu Xian was not in danger in the Terran Shijie, he naturally did not need to go to the Beibing Palace again.

When Mu Yuanshan wanted to continue talking, there was a sudden loud bang outside the courtyard of the Mu family, as if the ground was cracked by a landslide, and the entire Mu family's compound shook violently.

"Mu Yuanshan, come up and die!" When everyone in the Mu family's courtyard was wondering where the loud noise came from, an arrogant voice suddenly appeared in the sky above the Mu family's courtyard.

Hearing this extremely familiar voice, Mu Yuanshan's face became extremely ugly, and he had been fighting with the owner of the voice for decades, even if he didn't look up, Mu Yuanshan knew who was yelling in the sky above Mu Mansion.

"Mu Yuanshan, yesterday because Lord Qiantian came to Shitang Town, let your Mu family escape, and today without the protection of the Qiantian King, I think you have something to rely on!" Li Qingyu glanced down lightly and said condescendingly.
