Yang Yu controlled the mysterious space, did not hesitate to consume liliang, and flew towards the black devil's lair as fast as he could, wanting to destroy the demon lord before they rushed back.

Su Mengqi and the others stayed in another small space that Yang Yu opened up in the mysterious space with his mind, and they were all blank and unaware of what was happening in the outside world.

All around them were gray, and everything in that mysterious space could not be seen by them, so Yang Yu deliberately opened up a new small space for them to stay in.

Yang Yu looked outside with a cautious expression, and after nearly a day and a night of galloping with all his might, he finally came to the Demon Mountain, the old nest of the Black Devil.

The Demon Mountain was hundreds of meters high, and there were faint traces of seals on it, constantly emitting a light that ordinary people could not detect.

At the entrance of a cave more than two meters high, the power of the prohibition outside may have been reduced a lot, and Xiaoyao and the others in the Yuanzong Realm could break it by joining forces.

And now they didn't strengthen the seal outside, and they thought that no one would come to the Demon Cave to die.

After the last test, Yang Yu learned that the mysterious space was simply the nemesis of prohibitions and seals, as long as he was in that mysterious space, he could arbitrarily pass through any prohibition and seal.

The remnant soul of the meteor hammer spirit said that this mysterious space is the space where a heaven-level secret treasure artifact spirit exists, and the level is higher than the level of the meteor hammer, and there is also the potential for evolution.

Yang Yu suddenly looked at the body of the mysterious space, and became very curious.

But now he didn't spend time studying the so-called space, what he had to do now was to kill the demon lord who had not yet advanced to the true god as soon as possible, and eliminate future troubles.

All the prohibitions were like garbage in front of Yang Yu, and he controlled the mysterious space. It was easy to enter the Demon Cave of Demon Mountain.

Walking along the winding steps, Xiangxia walked slowly, this place was simply a familiar road for Yang Yu, he had been here several times, but it only took a few minutes, and he faintly smelled a strong smell of blood.

He knew it was the smell of blood in the pool of blood, and he was in good spirits and continued along the steps, which were illuminated by the illuminated magic stones on the mountain wall.

A short time later, a huge pool of blood appeared in front of him. The pool of blood was more than ten meters in size, and it was full of crimson blood that kept tumbling.

On the surface of the blood pool, a thin film-like prohibition is still on it, and there is still a thumb-sized hole on top of the prohibition. Yang Yu was very familiar with it, it was corroded by his blood.

It is precisely because of Yang Yu's blood. Let the demon lord speed up the process of awakening. The Demon Lord, who originally took more than ten years to fully awaken, had already woken up in more than a year, and was impacting the True God Realm at this time.

Yang Yu stood in front of the blood pool and felt a lot.

The first time I came, I was caught by Xiaoyao, and he was still ignorant at that time. Nothing is clear, if it weren't for that mysterious space, he would have been refined by the demon lord now, and the human world might have become the paradise of the demon lord.

But this time it was he who took the initiative to come. The purpose is also very different, he wants to kill and enter the forbidden system, and then kill the demon lord.

"It's so rich in blood qi, it's hundreds of times stronger than the blood sea I was originally in, if I can absorb all the liliang in the blood pool, maybe I can evolve!"

At this time, Yang Yu's mind came with the idea of killing the sword spirit of the god-killing sword, and he was eager to enter the blood pool, greedily absorb the blood energy in the blood pool, and evolve himself.

Yang Yu usually did not restrain the Divine Sword and Yun Heng in the mysterious space, so that they could sense things in the outside world, and if there was anything that could help them evolve or advance, he would speak out immediately.

Just like now, Yang Yu suddenly received the message of the Divine Sword Sword Spirit, and he felt very surprised.

Since the battle with Xiaoyao in the Dark Devil Base Camp, he faintly felt that the Divine Sword was not as simple as it seemed, the Divine Sword could emit a rich bloody aura, and it could turn the people around him who were low in cultivation into machines that only knew how to kill, and even the people closest to him didn't remember.

In that battle, many black demon powerhouses lost their minds under the erosion of the strange bloody power of the god-killing sword, and suddenly attacked their friends and relatives around them, and they had no reservations.

Those bloody scars were originally very peculiar, and the god-killing sword was originally in a strange blood sea space, constantly absorbing the power of blood scars, and gradually achieving itself.

In every battle, the blood clouds on the god-killing sword will surge to varying degrees, and it will keep releasing blood-killing qi, although the blood-evil qi of the first few times is very light, after the battle with Xiaoyao, he discovered the magic of the god-killing sword.

"Tell me more about it!"

Yang Yu didn't rush to make a move, but was waiting for the reply of the Divine Sword to see what the Divine Sword was going to do, the mortal-level secret treasure already had a machine spirit, and he could choose the right thing to improve himself.

The Divine Sword was no exception, after sensing something conducive to his evolution, he immediately wanted to make some moves, but unfortunately he was imprisoned by that mysterious space and couldn't come out, as long as he sought Yang Yu's opinion.

The Divine Sword Spirit said excitedly: "Master, if I can absorb the bloody qi in this blood pool, I should be able to enter a higher level and enter the ranks of that spirit-level secret treasure in one fell swoop!"

Yang Yu looked at the prohibition on the blood pool, and said suspiciously: "There is a prohibition on it, do you have a way to absorb the blood evil qi inside?"

"What's the matter, you go directly into the prohibition, you can deal with the demon lord, and the god-killing sword can absorb the energy inside!" Yun Heng suddenly pursed his lips and said lightly.

Yang Yu nodded, and said lightly: "In this case, then let's act! Let's deal with the Demon Lord, and absorb that bloody qi with the Divine Killing Sword, maybe we can slow down the speed of the Demon Lord's advancement!"

The Divine Sword Sword Spirit said: "Master rest assured, as long as you enter the prohibition, everything will be handed over to me, this will be my greatest luck!"

"Okay!" Yang Yu nodded, thought for a while, and said, "How long do you need?" If it's too long, we won't have so much time to wait for you!"

"An hour is enough!" said the god-killing sword.

Yang Yu smiled lightly with satisfaction, his mind moved, and his body disappeared in an instant, entered the mysterious space, glanced at the blood pool, and suddenly jumped in.

After passing through that layer of prohibition, Yang Yu walked out of the mysterious space and truly entered the blood pool, and his eyes were full of bright red blood, and there was nothing else.

Yang Yu immediately took out the god-killing sword and threw it into the bloody sky, the god-killing sword was like a hungry wolf seeing food, and immediately detached from his palm, and the entire sword body continued to absorb the energy in the blood pool.

In just a moment's effort, Yang Yu was surrounded by a pool of blood, his whole body was covered with red blood, and even his eyes couldn't see what was inside, as soon as he opened his eyes, blood would immediately enter his eyes.

The blood seemed to have spirituality, but in a moment, the red blood entered his body along the pores on Yang Yu's body, and gradually merged into his blood.

After the blood entered Yang Yu's body, it gradually repelled the liliang in his body, and it was actually corroding his body, and in just a few breaths, he felt that something was wrong.

The liliang in his body was slowly decreasing, as if the liliang in his body was gradually being pumped outward, and the feeling of liliang diminishing made Yang Yu suddenly feel bad.

An invisible bloody aura suddenly entered his soul sea, conjuring up countless violent soul demons, raging in his soul sea, constantly absorbing the energy in his soul sea.

Those soul demons seemed to have sanity, after entering his soul sea, some of them began to absorb Yang Yu's soul energy, and some of them climbed onto Yang Yu's soul altar, constantly opening their bloody mouths, constantly gnawing at his soul altar.

On top of each soul altar, there were countless hideous soul demons lying on it, constantly biting at the soul altar, as if those soul altars were their best nourishment.

Yang Yu's head gradually became drowsy, becoming lazy, as if he was very accustomed to this feeling, and he was so drowsy that he was almost going to fall asleep.

Suddenly, a cold willpower suddenly rose from the bottom of his heart, instantly stimulating Yang Yu's nerves.

"Damn! This place is so weird, I almost fell asleep when I just came in!" Yang Yu muttered in a low voice, and immediately urged the Heavenly Transformation Technique, refining all the blood and evil qi in his body, and at the same time, he also urged the changes in the soul sea.

In his soul sea, the Heavenly Transformation Technique was suddenly driven, and the soul energy in the soul sea seemed to come to life, like a turbulent sea, instantly submerging all the soul demons who were absorbing the energy of the soul sea.

That soul energy seemed to have become a crusher that wore out living beings, suddenly enveloping all the souls and demons condensed by the bloody qi, and constantly grinding out those souls and demons in an extremely wonderful way.

Those soul demons were constantly struggling in the soul sea, constantly roaring silently, and even showing a look of fear, just now they were still warming their soul energy, but now they suddenly turned into terrifying beasts, instantly submerging them, and began to absorb their liliang in turn.

In just a moment's effort, those soul demons in the soul sea that were like essence were all wrapped and refined by the soul sea mixed with the effect of transforming the heavens, and his soul energy did not decrease, but increased a little.

Those increased soul energy was the result of refining those soul demons by turning the Heavenly Formula, not only making all the soul energy eaten by those soul demons spit out, but also hitching themselves on.

This mysterious soul sea actually has the function of refining the soul demons condensed by the bloody qi, and now it seems that those soul demons are simply the most haode soul tonic.

There is still an invisible bloody aura entering his soul sea, trying to devour his mind, occupy his body, and make him a beast that only knows how to kill.

Yang Yu smiled, felt the changes in the soul sea, and quickly urged the Heavenly Technique, constantly refining those soul demons with the same soul form as the swarming, and he was secretly happy in his heart. (To be continued......)
