The spiritual pet that has received many benefits is naturally very quiet and peaceful in its cultivation. After all, he was in the spirit beast bag, but he didn't stay comfortable in the open space of the cave.

The elixir and materials related to the spirit building period that were looted from the hall of Yi Ranzhuang were not exchanged for them. This kind of thing is exactly what is needed, where will it be handed over stupidly.

What was handed over before was nothing more than a specific amount of elixir that the sect designated for naming. As for the other good things, Han Caokou naturally kept them one by one.

Among them, the mysterious box that everyone fought for to the death had been easily lifted by the master of the Nightless King at this time.

What is stored in it is not some anti-heaven exercises, nor is it some panacea. Rather, it was a palm-sized mask made entirely of black silk.

The mask was mere and didn't see any effect. And it is impossible to drip blood to recognize the owner and use it urgently.

When Han Cao Kou was confused, he specially used means to try to break it slightly. As a result, whether it is a titanium glove, or a cloud-piercing bow, or a beast element. None of them could get a single scar out of it.

"Little grass. No more temptation. The mask is made from rare materials. Its body is indestructible, and you can't break it. If you think about it carefully, it should be a rare-level magic artifact. If you want to trigger, or you can only touch it after you have entered the Soul Building Period. "The Lord of the Nights didn't know when he appeared, staring at the mask, and Yu Yu explained.

"A rare-level artifact, it looks like a good treasure again. Since this is the case, I will continue to cultivate day and night, and go all out to attack the tenth-level Great Perfection realm. At that time, you can hit the spirit building period. Now that there are so many elixirs, there must be a good chance of victory. "Han Cao Kou couldn't figure it out, so he put aside his chores and concentrated on his cultivation.

For a period of time, the cave was surprisingly quiet. It can only be seen that the spiritual energy around Han Caokou is entangled, and the spiritual power in his body is often maintained in a full state.

On the floor in front of it were several white jade bottles, and the number of pills in them gradually decreased.

In the following year, Han Cao Kou swallowed many pills, not only the cost of the exchanged pills. Together with the top-grade pills specially refined by Xiao Xuzi, they were also consumed. Finally, he stepped into the ten-layer Great Perfection realm.

One day, Hancao suddenly woke up. He took out hundreds of spirit stones from inside the ring and stacked them beside him. At the same time, he placed the auxiliary pill specially refined by Xiao Xuzi in front of him.

As a result, the first pill was swallowed, and Han Caokou plunged headlong into closing his eyes and recuperating his mind.

A few days later, in the ten-zhang high sky outside the cave, a thick cloud layer magically gathered. Looking at its scope, it is as large as acres, and now it is like a funnel posture, turning into a small spiritual vein and slowly injecting into the cave.

Obviously, at this moment, the Han Cao Kou had already touched the aura vision of the Spirit Building Period, and began to impact it wholeheartedly.

The Soul Building Period is different from the Innate Period, and in all seriousness, each realm is a watershed.

The innate stage is only the beginning of the foundation of the long journey of immortal cultivators, and every time they ascend their cultivation, they use the stored spiritual power to break through the acupoints. So as to complete the impact and perfection of the aura vortex again and again.

Nowadays, people in the innate stage, if they want to successfully advance, they must break through the last whirlpool. Break the aura vortex and turn into a sea of aura to successfully step into the spirit building period.

This may seem like a simple step, but it is actually tedious and difficult. It can be said that it is easy to say, but difficult to do.

The white snakes and foxes in the cave, as well as the golden silkworms, are hiding at the door of their respective rooms, snooping and observing the master's advancement.

Being able to cause such a lot of movement, even if it is a spirit pet, it is impossible to concentrate on cultivation, so as to watch the master's actions from the sidelines.

Not only that, but the two babies of Sleepless Jun and Xiaoxuzi also appeared and hid in the side to observe.

The three spirit pets faced the appearance of the two little babies, and their eyes were full of surprise. I wanted to express something, but I was suppressed by the baby's spiritual pressure, and I didn't dare to speak out for a long time.

The fox is extremely intelligent, and he knows early on that there is a master in his master's body. Now when I see it, it is not true. Although the baby in front of him is small, it gives people a deep look of jealousy.

Xiao Xuzi was too lazy to pay attention to the thoughts of the three spirit pets, and said lightly with his hands wrapped around them. "After waiting for so long, it's finally the first step. It's a tough journey. ”

The scarf baby Buyejun touched his chin and said with some seriousness. "Building the spirit is only the first step, and then there are the realms of Yuan Dan, Turning Infants, Chong Void and so on. I really don't know when we'll be able to get out. What's more, after building the spirit, the opponents that Xiaocao will face will gradually become stronger. The places you want to go are all places where life and death are uncertain. It is not easy to cultivate the road of immortals. ”

"I said Nightless King, now there is obviously hope, but when it comes to your mouth, there is little hope. Do you still want to be free and return to your ontological strength?" Xiao Xuzi glanced at the Nightless Monarch and said quietly.

The Nightless King sighed faintly, and did not say anything more.

The spirit pets on the side could hear it clearly, but they didn't know the meaning of the babies' words. It's really confusing.

At this time, Han Caokou directly ignored the existence of spirit pets and babies. It is in the midst of a wholehearted rush.

The rich aura at the top of the cave house slowly poured into the Heavenly Spirit Cover, and the aura vortex in the body expanded like never before.

Han Cao Kou just felt that this energy was extremely large, causing the aura vortex to grow bigger and bigger. There was a faint look of severe pain in the dantian, and the whole face became a little blue.

And Lingzhi is a little numb with pain, obviously this first step is so tormenting, I really don't know what other torture will appear in the next step.

Then came down, Han Caokou endured the pain, gritted his teeth and persevered, and slowly dredged the points in his body. Finally, an hour later, the entire aura vortex reached its expansion limit, shattered in the blink of an eye, and dissipated into a huge spiritual source in the air.

At this time, Han Caokou's face was pale, and he didn't have any mana in his body. When he slowly opened his eyes, he looked up at the sky. I saw that the aura cloud above the sky had turned into two acres in size, showing a rich aura inside, and a little bit of stars were faintly shining, which was very interesting to watch.

Han Caokou swallowed the two Soul Pills without hesitation, and the bottle containing the Spirit Pill was directly held in his hand and never put it down.

The shattering of the aura vortex is only the first step, and the next step is to condense the sea of aura. The mana in the body is greatly improved, so that it can support the cultivation of spells and other magical powers.

This may seem like a simple step, but it's actually dangerous.

The aura stars in the sky contain incomparably powerful energy. If there is no channeling of the Spirit Pill, all the energy will be swooped down in one fell swoop. No matter how powerful you are, you can't swallow a mouthful of an elephant in one go, and you will die immediately.

In the past, disciples who did not have the Spirit Pill were forced to attack, and many times they died at this step.

Except for those disciples who are gifted and have superior spiritual roots. They all have an innate ability to channel, and even if they don't have a spirit pill, they can safely condense the sea of spiritual energy.

However, today's Han Cao Kou is not a person with a heavenly spirit root, but a five-spirit root with a poor spirit root, which is a low-level talent. When rushing through the level, there was no preferential treatment at all, so he could only rely on the Zhuling Pill to assist.

Han Cao Kou thought in his heart, and the Lingyuan starlight in the sky swept down in a tornado. When he threw himself on his body, he suddenly felt pain, as uncomfortable as a thousand cuts.

The Spirit Pill formed a light mask, which quickly combed this force to a large extent. But in the next moment, it couldn't be suppressed, and it shattered away suddenly.

Obviously, the first attempt, Han Cao Kou failed, and his face became a little gloomy.

However, he didn't give up, and he still had so many spirit pills in his hand, and he was not afraid of not being able to condense the sea of spiritual energy.

In the following hours, Han Cao Kou swallowed the spirit pills one after another. As a result, there were seven or eight failures. Fortunately, it is taken every time, and even if it fails, it is a small loss.

The more failures he had, the more lessons he learned.

With another new beginning, Hancao Kou swallowed five Spirit Pills in one breath without regrets.

The sheer force of channeling is like a huge loophole overhead. The magic technique in his hand changed a few points, and he immediately urged all the spiritual source stars to pour into the funnel in one breath.

With such a move, Han Cao Kou felt more comfortable this time to guide the spiritual source star into the dantian, gradually condensing it into a sea of spiritual energy.

Han Caokou is not a very smart person, and he has some ability to dance and write ink in the mortal world. For this immortal cultivation world, it is an ant-like existence.

Three days later, all the spiritual source stars in the sky had disappeared, and they had already been integrated into the body by the cold grass to form a sea of spiritual energy. And the huge aura cloud still did not dissipate, and it showed a colorful light, as if some calamity had occurred.

At this time, Han Cao Kou sat on the ground, and the sea of spiritual energy in his body had already taken shape. A huge amount of mana slowly emanated from it, and when you reached out and grasped it, you could feel the powerful mana. Compared with the time of the innate period, it can be said to be more than a star and a half.

When he looked up again, the cold grass was shaking and bleeding without a cloak behind his back. The Cloud Piercing Bow immediately held it in his hand, ready to do it at any time.

After the aura vortex burst, it condensed into the sea of spiritual energy, obviously entering the spiritual building period. However, there is one last step of baptism, and that is the baptism of the power of the five elements of gold, wood, water, fire, and earth.

Once you bear it, you can perform the Five Elements Retreat Technique and become a true Spiritual Cultivator.

This level can be described as the last moment. The baptism of the five spiritual powers, as long as one of them is unbearable, is declared a failure of the advancement. All the work done before was wasted.

This baptism of the power of the five elements is okay, when you advance in the upper realm. There is often a Heavenly Tribulation for trials, and the Heavenly Tribulation from the laws of heaven and earth is the ultimate nightmare for many cultivators.

Immortal cultivators are originally going against the sky, and every time they advance, they will improve their cultivation and longevity. The laws of heaven and earth have their own laws, and they are treated fairly to every immortal cultivator, and they take the trial of the Heavenly Tribulation.

Those who can survive are the strong, and those who die in them can only be said to be lacking in strength. This is also the law that the strong survive and the weak are eliminated.

Suddenly, a metallic aura appeared in the clouds in the sky. Its form is like rain, its form is like a sword, and it comes with a strong wind.

This metallic aura is not a living thing, and the Flying Eagle Soul Strike will not work. Han Cao Kou continuously pulled the bowstring three times in a row, and suddenly shot out three huge spiritual energy arrows.

Thunder exploded three times in mid-air, and seven-tenths of the golden light suddenly disappeared. The remnants of the golden light slipped through the net, slamming on the cold grass kou, and was blocked by its bloody cloak.

As the golden aura dissipated, Han Caokou glanced at the cloak behind him, and half of the cloth had been lost. I never thought that the power of the five elements would be so terrifying, and a baptism would be half of the defense.

When he hesitated, the sky was immediately descending from the wood attribute aura. There was no other way for the Coldgrass Kou to shoot countless tiny arrows from within the Cloud Piercing Bow.

Such attacks, though powerful, do not help. In the blink of an eye, he was devoured by the wood spirit qi and rolled headlong into the cold grass kou.

After a burst of glow, it disappeared again. The bloody cloak behind the cold grass coward was only an inch of cloth left, and it was impossible to defend again.

Han Cao Kou was also simply, and directly withdrew the Cloud Piercing Bow and the Blood Cloak. At such times, we cannot pin our hopes on two treasures.
