"If the soul melt is successful, the next step is to refine the huge amount of essence blood. ”

Tuoba Aoyu stared at the seven souls in his hand without blinking, and his pulse sense entered the body, and the rolling qi and blood turned into a pillar of blood and rushed out from the heavenly spirit cover, under the control of his pulse sense, soon, the majestic and vast column of qi and blood was compressed into drops of pure and flawless essence blood, and then, turned into a ray of blood, and rushed into the fused seven souls drop by drop.

But listening to the sneering sound endlessly, the seven souls under the rush of the essence blood, bursts of white smoke floated, the volume of the seven souls was rapidly shrinking, Tuoba Aoyu's face was pale for a moment, fortunately, although his soul melting was not easy, but the tenacity of the seven souls was also rare, therefore, although the essence blood was domineering, it could not all turn the seven souls into nothingness for a while.

A few breaths of time passed, and a small part of the essence blood had been integrated into the Seven Souls, and just as Tuoba Aoyu had the next move, a whining and mournful sound suddenly came from the demon cave.

Immediately afterward, Tuoba Aoyu saw a terrifying hellish scene appear in front of his eyes.

The hundred ghosts roared violently, the evil spirit filled the sky, the crying was endless, the sky was gloomy, the ground was stained with blood everywhere, like an inch of demonic soil, the thick smell of blood in the air spread, and a sense of great sorrow and great suffering spread, sweeping Tuoba Aoyu's heart.

At the same time, an inaudible staccato sound came into Tuoba Aoyu's ears.

"Help me, save ... I, save... Save... Me!"

At the critical moment of refining the essence blood, the appearance of this terrifying vision was undoubtedly fatal to Tuoba Aoyu, his eyes flashed with murderous intent and he snorted coldly, and his right pupil was full of red light, shattering all the illusions in front of him into nothingness.

However, although the illusion was broken, the intermittent sound in the demon cave still existed, and Tuoba Ao Yumai Jue glanced at Senior Sister Mu Yunyao and found that he didn't perceive all this at all.

With one mind, Tuoba Aoyu decided to break through the Battle Spirit Realm first, ignoring the mutations in the demon cave for the time being.

In a few moments, the seven souls and the essence blood blended, a fist-sized blood ball exuding a crystal luster appeared in his hand, the blood ball condensed out, a huge suction force unfolded, directly devouring and absorbing the essence of the eight directions, the surrounding energy was all submerged into it, only a moment later, a huge essence vortex appeared around Tuoba Aoyu, and the energy from the outside world was still constantly pouring into the blood cells, and the volume of the blood cells began to slowly increase.

Suddenly, the blood cells were divided into three, arranged in a three-legged manner, each blood cell began to emit bursts of suction, three vortices were formed, and the range of energy devouring suddenly expanded, directly turning the three-foot radius into an energy vortex, and the energy of the upper vein was originally blessed by the formation, extremely rich, not at all worldly general mixture, at this moment, under the full absorption of Tuoba Aoyu, the rich energy essence became viscous, as if it was about to turn into liquid.

The expansion of the whirlpool soon affected Mu Yuyao, who was cultivating, his willow eyebrows frowned slightly, his body flashed, he retreated, and his eyes were full of surprise when he looked at Tuoba Aoyu.

"What kind of bloodline is he? This kind of momentum is too huge!"

The condensation of the three vortices into a spirit body requires a vast amount of energy, and it is simply impossible to complete it in a short period of time.

At this moment, a dark storm of demonic mist suddenly rushed out of the demon cave, and the wind blade at the entrance of the cave was directly involved in it, Mu Yuyao witnessed this scene, her pretty face changed color, her body was like electricity, and she quickly stepped forward, wanting to drag Tuoba Aoyu away, and shouted in her mouth: "Senior brother, retreat!"

Tuoba Aoyu had a trace of defense against the demon cave as early as after the illusion appeared, and at this moment, seeing the dark storm suddenly rushing out of the demon cave, his face changed, the fierceness in his eyes suddenly appeared, and he gritted his teeth suddenly, and the beast pattern on his body glowed with a strong light, and directly broke through the essence energy storm to a radius of ten zhang in an almost predatory attitude.

It can be seen with the naked eye, the tumbling and surging essence is quickly replenished into the three blood cells, and the three blood cells expand rapidly at an astonishing speed, which is completed when the pitch-black storm rushes to Tuoba Aoyu's approach, and then returns to Tuoba Aoyu's body.

However, the storm was too fierce, and he directly involved Tuoba Aoyu, who was glowing with a strong light on his body, and then, the scope of the pitch-black storm suddenly shook, and in Mu Yuyao's horrified eyes, he was also involved in the storm.

In less than three breaths, the storm swept Tuoba Aoyu and Mu Yuyao into the demon cave, and the outside of the demon cave returned to its previous peaceful appearance, as if nothing had happened, but outside the cave entrance, there were clearly two people missing.

It seemed that a thousand years had passed, and it seemed to be just a moment, Tuoba Aoyu's fingers moved, and slowly opened his sleeping eyes, and the memories in his mind came in a row, and he instantly remembered everything that happened before, and his heart was slightly shocked, and he raised his eyes to look.

"This is the inside of the Demon Cave?" Tuoba Aoyu was secretly shocked in his heart, he didn't see the dark storm sweeping over him.

The whole demon cave was gusting with gusting winds, and its interior was extremely wide and pitch black, and from time to time there was a ghost crying wolf howl, and it was impossible to tell what was coming out.

The range of his pulse was greatly condensed, and he could only see the range of two zhang around, three meters away, Mu Yuyao was lying quietly on the ground, there were streams of black qi flowing in her body outside her body, her head was also wrapped in black qi, and her face showed a painful look, as if she was suffering from inexplicable pain.

"Third Senior Sister!"

Tuoba Aoyu was startled, and then remembered that at the critical moment, Mu Yuyao reminded herself loudly that her body was also rushing towards herself, wanting to save herself, but she didn't expect that she was actually taken to the demon cave by the dark storm.

Grateful in his heart, Tuoba Aoyu knew that Mu Yuyao should be a person who is cold on the outside and hot on the inside, took two steps forward, straightened Mu Yuyao's body, and his pulse probed into his body to find the source of Mu Yuyao's coma.

In an instant, his eyes showed a solemn look, Mu Yuyao's body, there seemed to be a demonic force surging, constantly eroding his mind, if there was no external force inserted, the situation was afraid to be very dangerous.

"Oops, the demonic nature in my senior sister's body is constantly growing, I'm afraid she can't suppress it, how can this be good?"

Mu Yuyao was swept into the demon cave by the pitch-black storm in order to save Tuoba Aoyu, and at this moment, Tuoba Aoyu saw that he was in danger, and he felt a little unhappy in his heart, and couldn't help but be secretly anxious.

"By the way, why am I fine?" Seeing Mu Yuyao's strange appearance, and then thinking of himself, Tuoba Aoyu showed a puzzled expression.

After a little hesitation, Tuoba Aoyu had an answer in his heart, "Is it the red pupil?"

In addition to the strange red pupils, Tuoba Aoyu really couldn't think of anything else in his heart that could keep him from being eroded by demonic nature, thinking of the red pupils, he immediately took action.

A suction force suddenly came out of the red pupils, and it was visible to the naked eye, the black qi outside Mu Yuyao's body was slowly dissipating, but soon, Tuoba Aoyu's face suddenly turned pale.

He found that as the red pupil sucked out some of the demonic qi on Mu Yuyao's body, the qi and blood in his body were constantly pouring into the red pupil above, consuming at an alarming speed.

And he, in the demon cave, can't absorb energy to replenish his body.

This discovery made Tuoba Aoyu's face even paler, if he ran out of qi and blood, then he ......

He didn't dare to imagine the consequences.
