Speaking of this netherworld, it was taught to him by the Infinite Cave Master.

It is divided into seven layers in total, and with each layer of practice, the spiritual pool in the body will expand by one point, and the spiritual power will become more and more powerful.

The current Xiao Yubai has cultivated to the fifth level of perfection, which is more than three times higher than the spiritual power in the body of an ordinary foundation building stage cultivator, which is also one of the reasons why he has been in Qingyang City for many years.

At the same time, this Nether Skill also contains many offensive and defensive means, such as Nether Blood Hand, Nether Sword, Nether Shield, and so on.

The deeper the spiritual power in the caster's body, the more powerful these spells will become.

These spells are generally not used by the white bone old devil, mainly these spells consume too much spiritual power, and the spiritual power will be exhausted in a few strokes.

Compared to the Netherworld, it is naturally more convenient to use the best spiritual weapon against the enemy.

Now that there is no top-grade spiritual weapon, the white bone old demon must take a good look at the Netherworld, and then the martial arts competition will have the power to fight.

"Apprentice, I have to retreat for a day as a teacher, you go outside to protect the old man, and you can't let anyone disturb me. Xiao Yubai instructed Murong Yan on the side.

"Okay, then the master can call me if you need anything. ”

Murong Yan obediently left the room.

Seeing this woman leave, Xiao Yubai began to concentrate and sit up with his legs crossed.

At this moment, he kept recalling the fifth mental method of the Netherworld Gong, and the spiritual power in his body began to continuously converge to the dantian.

He first operated his spiritual power for one big week, and then five for five small weeks, and so on several times, and his consciousness gradually fell into emptiness.

After about a cup of tea, Xiao Yubai's eyebrows suddenly moved, and his heart was overjoyed.

The sixth layer of the Netherworld Skill, which had not been able to break through for many years, had a faint sign of loosening at this time.

This discovery is amazing, if you can break through the sixth layer, the spiritual power that can be stored in the body will increase exponentially, and then you won't want to fight.

As soon as he wandered, the spirit pool, which had been somewhat loose, stabilized again.

At this time, he didn't dare to be distracted anymore, and hurriedly ran the Netherworld Gong again, and waves of spiritual power frantically impacted the spirit pool.

I don't know why, every time I hit the spirit pool in the past, I was in great pain, and I even fainted.

This time, instead of feeling the slightest discomfort, the white bone old demon felt a sense of mental shock.

Thinking of the experience of cultivating the Netherworld Skill in the past and hitting the first layer for several years, Xiao Yubai was ecstatic, if he continued to rush like this, he might even break through the seventh layer of the Netherworld!

However, after these few rounds of impact, there is not much spiritual power in his body.

Xiao Yubai opened his eyes, and as soon as he patted the storage bag, hundreds of spirit stones fell in front of him.

He didn't think about it, grabbed a handful of spirit stones and absorbed them.

After half a burnt of incense, the spirit stone in his hand was completely spiritual, and it turned into a pile of ordinary stones.

The white bone old demon smacked his lips, the speed of absorbing spirit stones in the past was not so fast.

"Is it because the old man's soul has crossed and his body has undergone some kind of mutation?"

He remembered that the Wuji Cave Master had said that the more powerful the Divine Soul, the more effective it would be to cultivate the Netherworld.

Now, it seems that this is probably the case.

"Haha, it's really exhaustive, and there is no way out, when the old man practices the seventh netherworld, he must arrest all the people who offend the old man first, and torture them for a few years, and then talk about ......"

What he said in his mouth was naturally a rootless Daoist, followed by the Master of Emptiness, when this monk sneaked up on his palm, he had to miss the third-order demon beast.

With such a big hatred, how can the old demon of the white bones forget.

The more he thought about it, the more excited he became, and he grabbed a handful of spirit stones and began to absorb them.

About an hour, Xiao Yubai's energy was full again, and now he laughed, and without saying a word, he ran the Netherworld Gong and began to frantically impact the spiritual pool in his body.

The pool, which was originally the size of a fist, was loosened again at this time.

After repeating this more than a dozen times, Xiao Yubai only felt a loosening in his body, and a cool pleasure traveled through his body.

The fifth layer of Netherworld Gong has broken through!

Now the spiritual pool has expanded to the size of two fists, and the spiritual power in it is flowing, as if it is overjoyed because it has obtained a larger place.

Xiao Yubai was also a little physically and mentally exhausted at this time, panting heavily.

This time, it took almost twenty times to break through the spirit pool, and if it weren't for his divine soul mutation, I'm afraid it would have taken at least five years to have the current results.

And the process is far from being as easy as it is now.

He didn't continue to cultivate, but stood up, his eyes showed a solemn look, and he said in a low voice:

Nether Shield ......

With a "zi" sound, a layer of black and red light condensed on his outside, and the light flowed, exuding a powerful aura.

Looking at this light mask, Xiao Yubai's eyes flashed wildly, and his mouth trembled a little.

"The old man's Nether Shield has finally been upgraded!"

There are four stages of this Nether Shield Avatar, the first stage is a white mask, the second stage is a black mask, and the current black and red shield is the third stage.

The Infinite Cave Master had said that this third-stage Nether Shield couldn't even be easily broken by the best spiritual weapons.

With this shield, what kind of bird has no roots, the next time you encounter it, you will be beaten to death.

At the same time, he also experimented with other supernatural powers, and sure enough, they all increased, and they were no weaker than the mystery of this shield.

After trying out the supernatural powers, Xiao Yubai frantically gathered the spiritual power in his body on his legs and made a fierce effort.

With a "whoosh", he directly turned into an afterimage and smashed the door and rushed out.

After a few breaths, he came to a secluded alley in the valley.

Xiao Yubai looked at his legs in surprise.

Grandma's, now even the speed has nearly doubled.

Just when he was overjoyed, a divine consciousness sounded in his mind:

"Dao is friendly and fast, but why only the mid-stage cultivation of the foundation must be hidden. ”

Xiao Yubai frowned, followed this divine sense and went back directly, and soon found the person who spoke.

The man was standing in a gazebo a hundred meters away, smiling at himself.

I saw that the other party was in his forties, with fair skin, holding a turquoise flute in his hand, and dressed as a Confucian student.

"Hmph, Your Excellency's breath is not weak, and you can detect the old man so quickly. Xiao Yubai returned with an indifferent face.

In fact, he was comfortable in his heart, that Confucian cultivation had reached the late stage of foundation building, and he had never been so confident in front of the late stage monks.

"Whereever, where, it's just that I'm more sensitive to breath. Confucius snorted and continued: "Why don't you come and drink two cups, let's make friends." ”

Xiao Yubai thought about it for a while, but still rejected the other party.

Now his strength is not stable, it is better to keep a low profile.

The main thing is that I suffered the loss of the rootless Taoist last time, and my vigilance is a bit serious.
