However, this is nothing to Situ Yu, the Heaven Swallowing Spell can refine any vitality, whether it is pure yang qi, or pure heaven and earth aura, or extreme yin qi or demonic qi, it makes no difference to Situ Yu, and this Xuanyin Valley is on the vein of the earth's yin, and the yin qi is in the end, it is a deadly forbidden place for others, but for Situ Yu, it is a holy place for cultivation.

Of course, in addition, there is another reason that there are several corpse kings who have not fallen in his Sumeru Ten Thousand Law Rings, which is his secret and the deepest hidden hole card, Situ Yu cannot easily expose this hole card, so he chose this Xuanyin Valley, firstly, the strong earth yin qi can cover up the corpse qi on the corpse king, and it is because this earth yin qi is also a huge tonic for the corpse king, which has great benefits.

In the dark valley, there are steep cliffs on both sides, strange stones are standing around, the area of Xuanyin Valley is not large, about a radius of about 100 meters, in this valley, even the soil is dim, occasionally there are some strange plants growing in some places, extremely lush, even Situ Yu can't name it, there is a deep pool with a diameter of about 20 meters under the rock wall on the right side of the valley.

At this time, Situ Yu was standing on the edge of this deep pool.

"Goo-Goo......

The water in the deep pool kept stirring, as if it had been boiled by a fire, tumbling and tumbling, and every bubble appeared, and streams of cyan mist sublimated upward, making a large area of cyan clouds and mist formed over the entire deep pool, which was very strange.

"It's so cold!" Situ Yu frowned slightly, looking a little surprised.

Of course, the white gas coming out of this pool is not hot gas, and the tumbling water waves are certainly not really boiling, on the contrary, it is a phenomenon that is formed because the water in this pool is cold to the limit.

Even Situ Yu standing next to him couldn't stand it, and couldn't help but shiver.

If this is an ordinary person, I am afraid that just by approaching this secluded pool, he will be hit by the terrible cold air and immediately freeze to death.

It is strange to anyone that the water in this secluded pool has obviously reached the limit, and even his spiritual cultivation can't withstand the cold, but this water is not frozen.

Situ Yu shook his head, there are many wonders in this world, and many secrets are not yet what he can know now.

Skimming the thoughts in his heart, he raised his hand and waved, and immediately seven figures rushed out of the Sumeru Ten Thousand Dharma Rings.

The dozens of corpse kings who surrendered to Situ Yu and were included in the Sumeru Ten Thousand Law Rings are now only eight left, and all the rest were used as cannon fodder in that escape.

The remaining seven are all top-notch existences, in addition to the three major military masters of Greed, Giant Gate, and Wuqu, there are also four, one of which is of course a blood famine, which is currently the realm of the seventh level of the Corpse King, and the remaining three are called Enma, which is the realm of the eighth level of the Corpse King, and the remaining two are called Blood Spirit, Blood Abyss, all of which are the realm of the seventh level of the Corpse King.

These seven corpse kings, any one of them, in terms of real strength, must be above Situ Yu, the master. It can be said that this is Situ Yu's biggest help at present, which is completely equivalent to having seven super bodyguards. Of course, unless it is a last resort, Situ Yu will never expose this hole card.

"Demon Lord!" As soon as the seven corpse kings appeared, they all saluted Situ Yu respectfully.

"You can cultivate here for the time being, I believe that this earthly yin qi should be of great help to you. Situ Yu nodded and said.

The Seven Great Corpse Kings were overjoyed when they noticed the strong aura of the earth yin around them.

"Here...... This is actually the vein of the earth's yin, which is great, cultivating here is even ten times, a hundred times faster than we are in the ghost capital. Greed glanced around, feeling the extreme yin qi in the air, and couldn't help but say in surprise.

"That's right, under such circumstances, I'm afraid it won't be long before I can reach the realm of a demi-saint, even if it is impossible to attack the Corpse Emperor. Jumen couldn't help but howl in surprise.

Situ Yu smiled, and after a few orders, he found a clean place next to the secluded pool to cultivate.

Of course, he is the one who has benefited the most in the Demon Domain, except for the mysterious woman, and there are many benefits of these things, he has not had time to digest them, and it is rare to have this opportunity at present, of course, he must be afraid to consolidate his own cultivation.

"First of all, the Soul Dementor Demon Sound Skill will be successfully cultivated!" Situ Yu thought in his heart, this Soul Dementor Demon Sound Skill was no less than the Xuan Ming Decision, and if the cultivation was successful, it would have great benefits to Situ Yu's soul transformation.

At this point, Situ Yu retreated and cultivated in the Xuanyin Valley in the Cloud Canyon.

Time flies and creeps through your fingertips.

More than half a month has passed in an instant.

Situ Yu comprehends every day in addition to cultivation, and he can't take an inch, and when he reaches their realm, the demand for food is not so important, just absorb the aura of heaven and earth to replenish himself.

Layers of black light flashed out from Situ Yu's body, and suddenly, Situ Yu's originally locked eyes suddenly opened, and his hands quickly formed a wonderful mystical mark, and he pressed towards the void suddenly.

"Poof!"

A strange rune shot out of his hand, fluttering in the air.

"Zuihou's enslavement has finally succeeded in cultivating. Looking at the cyan runes flying under his control, Situ Yu couldn't help but smile with satisfaction.

After more than half a month of cultivation, the Soul Dementor Demon Sound Gong and the Six Kinds of Law Decisions have been absolutely cultivated.

At this time, this fluorescent rune is the soul mark derived from the slavery decision, and as long as this soul mark is punched into the soul of the person, it can be controlled by himself and absolutely enslaved.

At present, with Situ Yu's realm, he can only derive a maximum of nine soul marks, which means that he can only control nine people at most by virtue of enslavement, or nine spirit beasts with souls.

After receiving the soul imprint, Situ Yu let out a long breath of turbid breath, and looked at the seven corpse kings scattered around the secluded pool not far away, and couldn't help but make him slightly startled.

However, in just half a month, the aura on the bodies of these seven corpse kings was actually much thicker and stronger, and they had obviously received huge benefits in this Xuanyin Valley.

Especially the blood shortage, the blood qi on the body condensed, and the blood cloud formed on the top of the head kept trembling as if it were substance, and the breath had reached the edge of the eighth level of the corpse king, and I am afraid that it would soon be able to truly break through to the eighth level of the corpse king.

"Good guys, these corpse kings are actually cultivating faster than me. Situ Yu's expression moved slightly, and he said in surprise.

"However, with my current realm, there is still a lot of room for improvement in strength, and I am not in a hurry to break through the realm, the power of comprehending the law is fundamental, and it is the most critical place for Lingzun. Situ Yu frowned and pondered, thinking secretly in his heart.

"I will use this time to comprehend the power of the law, and strive to make the power of space and time to a higher level. After thinking about it for a while, Situ Yu decided.

When he was chased and killed by the Corpse Emperor, Situ Yu realized that although he had the power of the Ghost Shadow Miniature, which could be transferred instantly, after all, his comprehension of the laws of space was very limited, and the power of each miniature could only move a distance of hundreds of meters, such a distance was more than enough to deal with some Spirit Emperors, but if he ran into the Spirit Emperor again, it would be difficult to escape at the speed of the Spirit Emperor, and what if the other party was also a master who had comprehended the power of space?

That's why Situ Yu was so anxious to comprehend the power of space, and finally comprehended the power of the miniature of the ghost shadow step to the limit, and the farther the distance he transferred in an instant, he would be considered to have no worries at that time, even if he met the Spirit Emperor again, he could quietly slip away.

This means of escaping for one's life is the most important thing for any spirit.

Of course, in addition, Situ Yu also wants to comprehend the power of time to a higher level as much as possible, and it is best to be able to comprehend the top power in the Xuan Ming Duel, and at that time his strength will definitely be full, even if he faces the master of the seventh level of the Spirit Venerable again, he will have the power to fight.

After finding the direction of promotion, Situ Yu did not waste time in Lang and continued to cultivate quietly.

The power of the law of comprehension, one is the need for water drops and stones to wear the kung fu, slowly grinding, the time of enlightenment is long, of course, it will help, there is progress, this is also a lot of cultivation to the point of profundity, and some spirit emperors are always in retreat, and even some retreats are decades, hundreds of years are not uncommon.

The other is epiphany, but what this epiphany requires is luck in addition to talent. It's like a stroke of luck, and it's slim.

Another half a month has passed.

In the blink of an eye, more than a month has passed since Situ Yu entered the Xuanyin Valley retreat.

During this period, Situ Yu said that he comprehended the power of the law night and night, and with Situ Yu's talent and the secret books left by the Xuanming Sage back then, the progress was of course extremely fast, and it was not an exaggeration to say that it was a thousand miles.

In fact, among the many treasures left behind by the Xuanming Sage at the beginning, in terms of preciousness, it was actually the experience secret book that he had cultivated all his life, which was the most precious, especially for the spirit masters of the Spirit Venerable Realm and the Spirit Emperor Realm, it was simply the most precious treasure.

Because it contains a lot of information about the power of the Dharma.

This is also the reason why Situ Yu's power of the law has grown rapidly in the past half a month.

Although he failed to break through the realm, the current Situ Yu's whole person has a restrained aura, and he looks no different from ordinary people, and his cultivation is becoming more and more energetic, and his strength is many times stronger than before the retreat.

"With my current strength, I'm afraid that even if Lonely Wangtian is taking the Heavenly Emperor Huayang Pill once, I can still easily defeat it. A confident smile appeared on Situ Yu's face. After this retreat, the benefits to Situ Yu are indescribable.

First of all, the soul dementor sound skill is absolutely successfully cultivated, and the soul strength cannot be compared to even ordinary spirit emperors, and he can also manipulate illusions, and he will have a lot of soul attack techniques. In addition, he also has a very high comprehension on the laws of space, and if he casts the power of the miniature now, he can definitely move a distance of nearly a thousand meters in one step, which is three times as much as before.
