Black Cloud City.

After Nie Tianjiang spread the news of the imminent appearance of Tianmen through An Jia, Pan Tao, Jiang Lingzhu and others, he concentrated on cultivating in the Nie family.

He was also preparing to step into the gates of heaven.

When he learned through Hua Du that there was a Heavenly Gate that would be opened near the Prison Mansion away from the Heavenly Domain, and that the Qi Refiners who could enter the Heavenly Gate were all strong people of the acquired, middle heaven, and innate levels, he secretly became interested.

Not only the Heavenly Realm, but also the powerhouses of the Three Realms of other Domains will also enter that strange world through the three Heavenly Gates.

And he, now he only has the cultivation of the early stage of the Acquired Realm, which is the weakest realm level in the Three Days Realm, and with such strength to enter that strange world, he is very likely to become a lamb to the slaughter.

He had to be as powerful as he could.

In the stone room, he crossed his knees on the ground, using the qi refining technique to cooperate with the spirit stone in his hand to absorb the spiritual energy of heaven and earth, and perceive the changes in the spiritual sea.

In the vast sea of spiritual power, the spiritual power vortex slowly swirled, pulling the white vast spiritual energy near the spiritual sea, refining with the swirling of the spiritual power vortex.

He spied with his mind and found that the aura that was pulled towards the spiritual power vortex would reappear in the spiritual sea in a more dense and pure form after some refining of the vortex.

It's just that the condensed aura will appear in a ring on the outermost edge of the spiritual sea.

In his perception, the outermost edge of his spiritual sea, those white and vast aura, obviously had to be condensed and thick, and the power contained in them was also much stronger.

The aura that has not been refined, although it is also in the spiritual sea, is much thinner, and the power contained in it is much less.

Carefully observing the movements of the spiritual sea, the refinement of the spiritual energy by the spiritual power vortex, he gradually had an understanding of the cultivation of the acquired realm.

The cultivation of the Acquired Realm, due to the condensation of the spiritual power vortex, is many times faster than the speed at which the Qi Refining Realm gathers the spiritual energy of heaven and earth.

Those gathered heaven and earth aura were the first to escape into the vortex of spiritual power, and after the condensation of that vortex, they would become more refined.

After refining, the pure spiritual power was dispersed around the spiritual sea in a circular manner in a dense mist state.

The acquired realm will not continue to open up the spiritual sea, but will refine all the spiritual energy that originally existed in the spiritual sea over and over again.

After refining, the aura first appeared on the outermost edge of the spiritual sea, surging and squeezing inward in a circle.

In the process of refining, the spiritual power vortex will still continue to absorb the spiritual energy from the outside world, and cooperate with the original thin spiritual energy along the inner edge of the spiritual sea, condensing and refining one by one.

He carefully observed it and found that on the outermost edge of his spiritual sea, there were already circles of obviously thick and refined spiritual energy.

Those condensed spiritual qi will be pushed by the re-refined spiritual energy, slowly surging towards the direction of the spiritual power vortex.

The constantly swirling spiritual power vortex was like a well in the spiritual sea, and it was constantly absorbing the thin spiritual energy nearby, and with the re-introduced spiritual energy, it was refined over and over again when the vortex swirled.

After refining, the aura that became extremely pure sank sank at the "bottom of the well" and appeared on the outermost edge of the spiritual sea.

The outermost edge, those spiritual qi that has become pure after condensation, pushes the thin spiritual energy, and continues to merge it into that "well" and refine it again.

It's a cyclical process.

It's just that Nie Tian, who has just entered the Houtian Realm, hasn't even finished the first cycle.

After this period of cultivation, it was only at the outermost edge of his spiritual sea that a circle of refined spiritual energy appeared.

He still had a long way to go before the first complete refining cycle of the Spirit Sea.

He estimated that with his cultivation speed with the help of spirit stones, it might take another half a year to complete the first thorough refining of the spirit sea.

This is still the cultivation speed that can only be achieved with the help of spirit stones.

If he didn't have a steady supply of spirit stones, he might need three or five years to completely refine the thin spiritual energy in the spirit sea just by cultivating with the aura of heaven and earth.

At the beginning of the acquired realm, by the middle of the acquired realm, it may ...... It is necessary to completely refine the Spirit Sea more than once.

"It's hard work. ”

When he opened his eyes and looked out the window at the dark night sky, he sighed secretly.

He had long heard that the Qi Refining Realm was just the foundation, and only when he stepped into the Acquired Realm could he be called an entry-level Qi Refiner.

Starting from the acquired realm, every breakthrough in the realm in the future will be much more difficult than the advancement of the qi refining realm.

In the past, he didn't have too deep understanding, but now that he has finally stepped into the acquired realm, he truly realizes the wonder of the spiritual sea, and the mysterious refining process makes him understand...... The path of cultivation is really hard step by step.

"Even if there is a spirit stone given by the master, refining day and night, if you want to carry out a complete refining of the spiritual energy in the spiritual sea, it will take half a year. ”

"That cycle may be more than once, and it will continue to be refined again. ”

"After a few times, years have passed, and so on...... It seems that the threshold of breakthrough has only been reached. ”

"If you really want to leap forward, you also need the cooperation of your mood and your own understanding. ”

"The long road of cultivation, today, it turns out that it is just the beginning. ”

Nie Tian was full of emotion.

A Qi Refiner not only needs to cultivate, but also to practice and refine spiritual skills, comprehend the mysteries of spiritual techniques, and select spiritual weapons, trying to echo spiritual weapons.

There are also qi refiners, due to their talent and interest, they may also delve into the techniques of refining weapons to figure out runes and formations.

All kinds of ways to improve the strength of Qi Refiners will take a lot of time, and they need to be understood with heart.

And the lifespan of a Qi Refiner is not endless, only with the gradual improvement of the realm, the longevity will increase accordingly.

Many Qi Refiners have not yet broken through to the next realm, and they have not gained additional longevity, and their lives have come to an end.

He faintly felt that his master Wu Lin seemed to be ...... Now we are facing this tricky trouble.

"Only by cultivating at an extremely fast speed and advancing again and again can we increase our longevity and continue to cultivate. Looking at the dark and moonless night sky, he strengthened his resolve.

- Even if the realm is low, he will step into the gate of heaven as much as possible to go through the bloody trial.

A little firelight suddenly flashed in the dark night sky, and the firelight ...... It seems to be in the depths of the void, extremely bleak at first, but gradually clear.

"Tonight, there is no moon and no stars twinkling, how can there be fire?" he looked at the night sky curiously.

After a while, more fires appeared in the night sky, one by one.

For some reason, he suddenly felt a little depressed, just looking at the little fire, he felt that something big was happening.

After half a ring, more and more firelight became brilliant and bright, dragging colorful streamers, which looked extremely dazzling in the dark night sky.

"Shooting Star!"

In a nearby stone building, Jiang Lingzhu's exclamation was heard.

Nie Tian, who walked to the windowsill, saw Jiang Lingzhu and Ye Gumo, standing at the window, as if they were also watching the abnormalities in the night sky.

After a while, the clusters of meteors in the night sky became more and more distinct.

Hundreds of meteors, showing different colors of fire, are becoming more and more brilliant and dazzling, attracting everyone's attention!

"Meteor shower!

The Nie family, many children and juniors, cheered loudly and looked excited.

"Something isn't right......"

Looking at the night sky becoming more and more obvious, and the beams of meteors becoming more and more clear and gorgeous, Nie Tian's face was grim, and he faintly felt that something was wrong.

Those meteors didn't seem to flash away in the night sky, the direction in which they flew seemed to be the Heavenly Realm under everyone's feet!

"Before the Heavenly Gate appears, there will be signs in the Starry Sky Realm!"

He suddenly remembered what Hua Du said before leaving, and became more and more nervous, always feeling that the meteor that suddenly flew in the night sky was because of the gate of heaven!

"It can't really be a change caused by Heaven's Gate, right?"

Only half an hour later, there were probably nearly a thousand bundles of colorful meteors, dragging brilliant fire, and it seemed that they were close at hand.

Those multicolored meteors that had gathered together seemed to be affected by some strange magnetic field, and suddenly flew in all directions, completely scattered, and began to fall to the earth in various parts of the Heavenly Domain.

Among them, there were more than a dozen fiery meteors, coming in the direction of Lingyun Sect and Black Cloud City.

"What happened?"

"Oh my God, there's an extraterritorial meteorite falling!"

"Oh my God, how can this be?"

The clan elders of the Nie family were alarmed, and on the streets outside Black Cloud City, many people also gathered densely, all looking up at the sky, shocked.

At this moment, not only Black Cloud City, but also those nearby cities, Lingyun Sect, and the prison powerhouses surrounding Lingyun Mountain also looked up at the sky in fear.

In the land of meteorites where the Heavenly Domain is located, meteors often break through the sky, which is also the origin of the name of the land of meteorites.

But those meteors that pierce the sky often disappear in a flash and disappear quickly, and very few meteorites fall directly.

And tonight, those meteor showers that suddenly appeared in the night sky seem to have come specifically from the Heavenly Domain!

"Boom!

The earthquake trembled, and in the icy wilderness around Black Cloud City, it seemed that a meteor had fallen to the ground, and the terrifying impact and the shaking Black Cloud City were roaring.

"Lingyun Mountain!" Jiang Lingzhu screamed.

Nie Tian took a closer look and found that there were several flaming meteors, releasing flames of different colors, like a waterfall pouring down, and fell fiercely towards the surroundings of Lingyun Mountain.

"Boom, boom, boom!"

The nearby Black Cloud City roared endlessly, the earth shook, and many mortals vomited blood directly in their sleep.

Even Nie Tian was surging with qi and blood, dizzy and swollen.

He hurriedly sheltered his whole body with spiritual power, secretly gritted his teeth, and stared at the night sky.

"Whew!"

A beam of orange-red flame streamers suddenly became larger, like a gray boulder burning with flames, heading towards Black Cloud City.

"Boom!"

The flame streamer fell to the location of the Yun family, and the Black Cloud City set off a terrifying shock wave, and many mortals in the city let out a desperate cry.

"Boom!"

Most of the stone buildings of the Nie family collapsed suddenly, and the stone building where Nie Tian was located was no exception.

Frightened, he jumped out before the stone tower was reduced to rubble.

Standing on the cracked stone floor, he saw Jiang Lingzhu and Ye Gumo, as well as Pan Tao and others, all running over in fear.

He heard miserable wails from all locations in the Nie family.

Outside of the Nie family, in all corners of Black Cloud City, there were people crying loudly.

......
