After learning about the exercises in this fragment, Mu Xiao was already dumbfounded, what did he see, the Heavenly God Exercises, there really were Heavenly God Exercises in the world.

Today's gods are just ancient legends for the entire Eight Domains, let alone the Heavenly God Exercises, if there is really a Heavenly God Exercises in the world, I am afraid that all the supremes of the entire Eight Domains will come to rob it.

"Oh my God, I'm not going to be dreaming. ”

Mu Xiao even had an unreal feeling, and unconsciously pinched himself, yes, it hurt, it seemed that he was really not dreaming, he was very awake.

In the gradual understanding of these memories, Mu Xiao also knew the true identity of the Earth Heart Crystal.

It is recorded in the book that the formation of the Earth Heart Crystal is speculated to be the spiritual power of heaven and earth, with the precious spar as the core, constantly absorbing the essence of day and night and the energy of the earth, and finally gathering, but now Mu Xiao really understands that the memory fragments left by the Earth Heart Crystal are not the case.

The so-called Earth Heart Crystal is not based on the precious spar as the core, but after the fall of the ancient gods, there is a very small probability of retaining a certain divine soul, and the remnant soul of the ancient gods is the core of the earth heart crystal.

Because of this, after absorbing the Earth Heart Crystal, the remnant soul of the Heavenly God will also be completely released, and the resentment left in the remnant soul will devour the mind of the cultivator, but in the same way, if you can finally retain your own mind in such a situation, then there will be a great probability of obtaining the Heavenly God Technique like Mu Xiao.

This is the real danger and preciousness of the Earth Heart Crystal.

"Celestial exercises, interesting. ”

After learning the truth, Mu Xiao's eyes were full of blazing, if there was another Earth Heart Crystal, it would mean that he would be able to obtain another Heavenly God Technique.

But then he shook his head and smiled bitterly, if it wasn't for Hongmengzhu absorbing the resentment left by the Ziyun Heavenly God in the remnant soul in time, I am afraid that he would have been devoured long ago, and then absorbing an earth heart crystal, I don't know what will happen, but let's talk about it later.

Now that he has completely absorbed the energy of the Earth Heart Crystal, Mu Xiao has also successfully broken through the Foundation Building Realm, and has opened up the symbol of the Foundation Building Realm powerhouse in his body, the spiritual source.

"Hey, my spiritual source. ”

Just came to his senses from the joy of the Heavenly God Exercises, and saw the spiritual source in his dantian, Mu Xiao's eyebrows moved slightly, and his spiritual source seemed to be different from the spiritual source of ordinary people.

The so-called spiritual source is a space that can store spiritual power in the dantian, and what is stored in the space is the spiritual power of heaven and earth absorbed by cultivators when they cultivate, and they are used for their own use.

Within the normal spiritual source, the spiritual power should be like a thin mist, floating within the spiritual source, but with the improvement of the realm, the space of the spiritual source continues to expand.

But now in the spiritual source that Mu Xiao had just opened up, the concentration of spiritual power was not like mist, but like liquid, which seemed a little viscous.

This kind of spiritual power concentration and storage capacity is probably unmatched in the same realm.

It seems that the pain he suffered before was not in vain, and with such a spiritual source, it is worth it now.

Stood up and patted the dust on his body, I don't know how long I was delayed in this secret room, I successfully broke through to the foundation building realm, and it was time to go out.

Pushing open the stone door with a squeak, a strong sunlight pierced into his eyes, making Mu Xiao's eyes squint slightly, but then what caught his eyes was Jiang Qian, who had just stretched out his hand to push open the stone door.

Seeing that the stone door was opened, Jiang Qian's face was also stunned, and then a burst of joy permeated her pretty face.

"Mu Xiao, you finally came out, you stayed for a full five days. ”

Jiang Qian breathed a sigh of relief, she had been staying outside the secret room for the past few days, but five full days had passed, but she still hadn't seen Mu Xiao come out, she couldn't help but be a little worried in her heart, and she struggled for a long time before she thought about forcibly pushing the door in, who knew that it happened that Mu Xiao had also finished cultivating at this time and walked out of the secret room.

His eyes swept over Mu Xiao's body, although Mu Xiao's clothes were already soaked with sweat at this time, and even his body still smelled a little, but the faint spiritual power that was released was obviously the strength of the foundation building realm.

"You've made a breakthrough. Jiang Qian said with a smile, first to Fan, and now there is Mu Xiao, Jiang Qian is very happy that his students can break through to the foundation building realm one after another in the first year.

Mu Xiao scratched his head embarrassedly, he didn't expect that this breakthrough would take five days, I was afraid that it should have taken a lot of time to be pulled into the memory of the Purple Cloud Heavenly God by the white light cluster at that time.

"Fortunately, although it took a little more time, fortunately, I successfully broke through. ”

Jiang Qian lowered her head and smiled, her sleeves gently covering the tip of her nose, "However, it seems that you still have to go back and wash up well." ”

Hearing Jiang Qian's words, Mu Xiao's face suddenly turned red, and he raised his sleeve and smelled it, indeed, not only the smell of sweat, but also some impurities discharged from the body during the breakthrough, mixed with a strong sour smell.

"Uh, I, I'll go. ”

Mu Xiao said, hurriedly fled back to his residence, and slammed open the door, which startled Zhang Xiaofeng, who was meditating.

"Brother Mu Xiao, your breakthrough is complete. ”

Zhang Xiaofeng also heard Jiang Qian say that Mu Xiao had reached the critical moment of breaking through the foundation building realm in the past few days, but several days had passed, and there was still no news of Mu Xiaofeng, which made Zhang Xiaofeng a little worried in his heart, after all, it only took three days for Li Fan to break through the foundation building realm, but this time Mu Xiao took five days.

But now that he saw Mu Xiao return to his residence, and the momentum of the whole person had changed, Zhang Xiaofeng thought to himself, it must have been a successful breakthrough, and he couldn't help but be happy for Mu Xiao.

"Well, it took some time, but the result was good. Mu Xiao smiled, and then took out the wooden bucket directly from the storage bracelet, poured hot water into it, and jumped in after taking off his clothes.

The whole person lay down in the barrel, and the fatigue caused by the breakthrough in the past few days was instantly swept away.

With a deep sigh of relief, Mu Xiao put his hand on the edge of the barrel contentedly, and his eyes fixed on Zhang Xiaofeng's body, "Xiaofeng, you have broken through to the eighth level of the Tempered Body Realm." ”

"Yes, it just broke through yesterday. Zhang Xiaofeng said with a smile, since entering the Star Martial Immortal Sect, Zhang Xiaofeng has cultivated harder than everyone else, originally from Gushan Village, he does not have a strong force as a background, nor does he have a lot of resources to practice, all he can do is to put in more effort than others.

Such a person, Mu Xiao feels very similar to himself, has no power and power, and only has perseverance and heart that is not afraid of difficulties.

The corners of Mu Xiao's mouth were also filled with a smile, he was very happy that Zhang Xiaofeng was able to break through to the eighth level of the Tempered Body Realm so quickly, he naturally knew that in this, Zhang Xiaofeng had paid a lot of hard work that others could not imagine.

Clenched his fists, Mu Xiao felt the improvement of his own strength after breaking through to the foundation building realm, and sighed in his heart, isn't he like this, he often gets scars all over his body for cultivation, but fortunately, he has the existence of Hongmengzhu in his body, so he has no reason not to work hard.
