With the beginning of the advancement, the spiritual power and blood in Xuanyuan's body seemed to be ignited, and all corners of his body transmitted extreme pain to the spiritual sea at the same time. What's even more terrifying is that Xuanyuan's spiritual sea is already a torn pain. The heart is piercing, and thousands of arrows pierce the heart, I am afraid that I can't describe Xuanyuan's feeling at this time.

Ordinary people suffer under this kind of pain, even if they are not hurt to death, they will inevitably be tortured to the point of losing consciousness or even going crazy. But at this moment, Xuanyuan not only can't lose consciousness, but also has to maintain the posture of his body and the difficult operation of his spiritual power while enduring endless pain. After all, once he loses consciousness, not to mention that he himself will fail to advance, even if it is Xiaoyuan, he will lose the best opportunity to advance.

"Words and spirits are at will, pure heart!"

Enduring the severe pain, Regulus reluctantly cast a spell that would ease his pain. However, he only did this to numb his feelings a little, and it did not make his physical condition any better. Once the power of the spell was over, he would continue to be tormented by that pain.

The two of them broke through to the Dragon Emperor on the side, and they didn't dare to intervene. The dual cultivation of the two is an extremely mysterious process of power balance, if he makes a move at this time, he can relieve Xuanyuan's pain, but it may break this balance, causing the two to break through and fail. Therefore, all the Dragon Emperor can do is to continue to wait and see.

Xuanyuan's pain was because he was using his human body at this time to bear the pain of transformation when the Dragon Emperor's vein broke through. Due to the influence of the reverse scales on the two of them, Xuanyuan's advanced pain at this time is equal to Xiao Yuan, but Xiao Yuan has a large enough body to dilute this pain, but Xuanyuan has to bear it on the human body, so the difficulty is naturally self-evident.

The pain did not slow down with time, but intensified as the advanced pair continued. Xuanyuan wasn't sure if he would be able to hold on until the moment of a successful breakthrough.

"Husband......

As if feeling Xuanyuan's pain, Xiao Yuan, who was meditating deeply, slowly opened her eyes. Immediately after, a trace of blood emitting a golden light flowed out from Xiao Yuan's eyebrows, and flowed into Xuanyuan's body in the direction of the reverse scale.

"Hmmm......"

With the integration of the power of the Dragon Emperor's bloodline in this bloodstream, Xuanyuan's body suddenly lightened, and the pain in his body was instantly reduced by half. The feeling of comfort brought by the reduction of pressure made Xuanyuan snort, and the operation of the spiritual power in his body also became smooth.

Although enjoying the comfort brought to him by the blood of the Dragon Emperor, Xuanyuan knew that this was Xiao Yuan helping himself in a way similar to self-harm. Although these blood powers are not the most important essence blood, at this critical moment, losing even a little bit of blood power will reduce Xiao Yuan's potential after stepping into the Holy Rank by one point!

"Little fool, how could I make you suffer......"

Relieved his breath to Xuanyuan, he absorbed Xiao Yuan's blood as quickly as possible, and then, through the power of the reverse scales, he replenished the holy power that had already been prepared in his body to Xiao Yuan.

The second baptism of holy power was carried out after Xuanyuan initially stepped into the holy steps. Although Xuanyuan at that time could not really grasp the holy power, he could truly perceive the subtlety of the holy power, and when his spiritual power absorption of the holy power reached a critical value, he stored a part of the source of the holy power for Xiao Yuan in his body. And at this time, it was the best time for him to deliver these sources of holy power to Xiao Yuan!

Although Xuanyuan's holy power is the power of chaos from chaos, and the power of Futu in the demon capital, it is not the same as Xiao Yuan's own power to Sanskrit. However, Xuanyuan's holy power fed back to Xiao Yuan, but it was able to produce a kind of holy power resonance in Xiao Yuan's body, thus stimulating Xiao Yuan's perception of the power of Sanskrit. This kind of skill was quietly taught to Xuanyuan by the Demon Queen of the Demon Capital.

After receiving the injection of foreign holy power, Xiao Yuan, who was originally a little weak because of the blood, instantly became full of energy. In just a few breaths, the blood in her body was replenished, and the damage that could have been possible was also wiped out in an instant.

As the breakthrough continued, the holy power in Xuanyuan's body became more and more obvious. Having received the Holy Power twice to accept the Source Spirit, as long as the breakthrough is successful, he will definitely be able to master a certain amount of Holy Power, so the closer he is to the breakthrough, the stronger the Holy Power in his body will be.

On the other hand, Xiao Yuan's breakthrough is more reflected in the enhancement of the Dragon Emperor's bloodline. With every breath she takes, she will inhale some of the dragon qi in the dragon pool into her body, thus making the power of her bloodline stronger and more pure. At this time, Xiao Yuan, who had not yet succeeded in breaking through, had reached the level of the Dragon Emperor's bloodline in her body, which was not inferior to the Dragon Emperor. It was hard to imagine what level of bloodline would be strong when she really stepped on the Holy Rank.

The ascension of Xuanyuan's holy power and the ascension of Xiaoyuan's bloodline power gradually formed a state of mutual echo and mutual promotion. With the help of the connection of the reverse scales, the strength of the two is constantly increasing and promoting each other, and the road to breakthrough between the two has become more and more flat.

"Looks like it worked......

Seeing that a virtuous circle had formed between Xiao Yuan and Xuanyuan, the Dragon Emperor couldn't help but breathe a sigh of relief. Although neither of them had the experience of breaking through, they instinctively thought about each other, but they found a broad road to breakthrough between accidental collisions.

The breakthrough of the Holy Order is a complete transformation process. In this process, the cultivator's spiritual power will be replaced by the power of the Holy Source, thus allowing the cultivator to reach a completely new realm. When the spiritual power is completely replaced by the power of the Holy Source, it is the time when the breakthrough is successful.

The Dragon Emperor could feel that at this time, Xuanyuan and Xiaoyuan had already passed the most difficult initial stage, and then, as long as they continued like this, the two of them would be able to get the most perfect breakthrough.

However, just when the Dragon Emperor was relieved, in the Dragon Valley outside the Dragon Pool, a powerful aura suddenly came!

"Who dares to trespass into Dragon Valley?!"

Although he already had a guess in his heart, the Dragon Emperor was still extremely surprised. He couldn't believe that the guy who had just broken through the Holy Rank of the Ten Thousand Saints Pope really dared to contempt his existence.

"Dragon's Breath Guardian!"

Spit out a rich breath of the Dragon Emperor, the Dragon Emperor glanced at Xuanyuan and Xiao Yuan again, and then went out of the Dragon Pool. The dragon breath he left behind was enough to protect the breakthrough of the two from being disturbed, and it would not interfere with the two of them absorbing the power in the dragon pool.

"You break through with peace of mind, I'll take care of things outside!" A trace of anger flashed in the bottom of the Dragon Emperor's eyes.

The guy who came to smash the field at such a critical moment, no matter who he was, the Dragon Emperor would let him taste the bitterness!
