After completing several main missions, Shen Yuan has roughly figured out the key factors that affect the main missions.

Because the time interval is tens of thousands of years, many conditions required to complete the main task are difficult to meet, and can only be replaced to a certain extent with the help of other things.

During this process, if Shen Yuan gets something better to replace the original conditions, the main task will be upgraded, which will affect the final reward settlement of the main task.

For example, the sect spirit pond was replaced by the natural spirit pond, and the sect competition in which only the Luoyun Sect participated was replaced by a martial arts competition among all sects involving several blessed places.

In many cases, these changes were not made deliberately by Shen Yuan, but because the original conditions could not be met, so they could only be replaced in this way.

This process will not necessarily increase the difficulty, but it will be able to maximize the benefits and allow Shen Yuan to reap more benefits.

The "Square Inch Secret Realm" opened up by Shen Yuan in the endless void can also be regarded as part of the main mission of the secret realm trial.

From the original small secret realm to a small world with its own rules generated from the creation of the universe, this upgrade has far exceeded the level of the original secret realm trial. Once successful, the main task will inevitably be upgraded.

"The only concern is that the main quest clearly states that the main venue of the trial is Fang Cun Secret Realm. Replacing it with other small worlds may affect the judgment of the main quest."

Thinking of this, Shen Yuan frowned slightly and touched his chin, with a look of contemplation on his face.

After a while, Shen Yuan slapped the table and said to himself bluntly:

"Anyway, this small world is only tens of kilometers in radius, and its size can only be called a secret realm.

The size is a secret realm, and I, the creator, named it the Fangcun Secret Realm. So no matter whether it is a paradise or a small world, it is the real Fangcun Secret Realm!"

Having calmed his mind, Shen Yuan did not care about the details, but continued to focus on the Fang Cun Secret Realm.

Although the Fang Cun Secret Realm has been opened up, and the earth, water, wind and fire generated within it are extremely powerful, it is not a complete secret realm after all.

If such a secret realm is used as a trial, even a true spirit cultivator who steps into it will be wiped out by the chaotic rules of earth, water, wind and fire.

"We should sort out the earth, water, wind and fire, separate the clear and turbid qi and set order, and then gradually improve the rules of the Fang Cun Secret Realm."

Shen Yuan did not master the magical powers related to sorting out the earth, water, wind and fire. These magical powers have already involved the method of creation, which is definitely not something that can be passed down by ordinary Taoist traditions.

But Shen Yuan was not worried at all because he had already thought of finding another way.

The true meaning of Tiangang in the body was revealed, and the great supernatural power of Nine Breaths to Subdue Qi moved the Yuanqi floating between heaven and earth, slowly crossing it into the secret realm of only a few dozen kilometers in size.

Yuanqi is the root of all Qi and the most original Qi between heaven and earth. Its formlessness and intangibility also make Yuanqi have no bias in nature. It can be integrated with the many rules of heaven and earth to give birth to the Qi of heaven and earth.

In the secret realm of Fang Cun, when the world was first created, the earth, water, wind and fire were not yet determined, and all the rules were manifested between heaven and earth. It was the best time for the Yuan Qi to merge with the rules to give birth to the Qi of heaven and earth.

Shen Yuan was unable to pacify the chaos of earth, water, wind and fire, but if the Yuan Qi was integrated into the earth, water, wind and fire to give birth to the corresponding Qi of heaven and earth, Shen Yuan could use the Nine Breaths to Subdue the Qi to control it, thus achieving the goal of pacifying the earth, water, wind and fire and establishing order.

As Yuan Qi entered that chaotic world, the world within a radius of dozens of miles began to undergo earth-shaking changes.

The land between heaven and earth is constantly collapsing. Massive flames are gushing into the sky and turning into burning trees. Strong winds are howling and sweeping the sea of ​​fire. Waves are surging and submerging the earth.

All the rules became increasingly chaotic with the arrival of Yuan Qi. The power of heaven and earth was so turbulent that even Shen Yuan did not dare to step into it rashly.

Any cultivator who has not given birth to a Yang God and is caught in it will be completely annihilated by the earth, fire and wind disaster in an instant.

This is the change of rules caused by the fusion of Yuan Qi with earth, water, wind and fire, which promotes the fusion of Yuan Qi through repeated collisions of rules.

Normally, even if there are rules of heaven and earth for the fusion of Yuan Qi, the fusion process requires a long time to evolve.

Even the birth of each new kind of Qi of heaven and earth is calculated in tens of thousands of years.

But Shen Yuan obviously did not have so much time to wait, so he decisively used the Nine Breaths to Subdue the Qi to control the Yuan Qi, actively integrating the rules of earth, water, wind and fire when the world was first created, gradually increasing the speed of its evolution.

Time in the outside world is still passing, and in the blink of an eye, three days have passed.

With the secret courtyard as the center, the Yuan Qi covering an area of ​​hundreds of miles was almost completely plundered by the Nine Breaths to Subdue Qi magical power during these three days.

In an instant, the whole world was cleared.

If the area around Wencheng was not a barren land with poor spiritual veins, and the current environment was unable to support the birth of a Qi training cultivator, otherwise such a large-scale change in Yuanqi would have been enough to cause the Qi training cultivator to sense it.

After such a huge amount of Yuan Qi was led into the Fang Cun Secret Realm, the nurturing of the Qi of Heaven and Earth was also very effective.

Compared to the chaotic scene three days ago, the Fang Cun Secret Realm now seems much more stable. The earth, water, wind and fire that were originally constantly blending between heaven and earth are gradually separated.

The earth covers most of the secret realm, and the barren black land becomes the foundation of the world.

Opposite the earth is a deep dark blue ocean, with surging waves but divided by the shore, showing clear changes.

Strong winds howled above the earth, sweeping away everything; deep in the earth, magma flowed and flames roared.

In the core area where the four major rules of earth, water, wind and fire evolve, the auras of the four qi of heaven and earth are gradually becoming stable and will be completely fixed after three days of evolution.

On the earth, Kunling Xuanzhong was born from the earth veins and is the qi of the middle heaven and earth. Kunling Xuanzhong can control the earth's pulse and gravity, and it is easy for him to open up mountains and land with just a wave of his hand.

In the ocean, the Mingzhangyuanliu was born from the waves and is the qi of the middle heaven and earth. The Mingzhangyuanliu can regulate the waves of rivers, lakes and seas, and under its control, ordinary water can also become a natural disaster.

Above the sky, the Burning Wheel of Silence descended from the howling gale, and was the Qi of the middle heaven and earth. The Burning Wheel of Silence could lead the gale to turn into a tornado, and its wind column connected the heaven and earth, clearing the vastness.

Under the magma, the earth's lungs are molten gold, which is refined from the boiling magma and becomes the qi of the middle heaven and earth. The earth's lungs are molten gold, which can lead the underground magma to melt gold and smelt iron, and engulf all living things with disaster fire.

Under the rules of the world when the heaven and earth were first created, Shen Yuan used the great supernatural power of Nine Breaths to guide and successfully created the four middle-level Qi of heaven and earth.

In fact, with the status of the beginning of heaven and earth, it would be easy for the rules of gestation to produce not only the middle-level Qi of heaven and earth, but even the legendary top-level Qi of heaven and earth.

But the problem is that the secret realm is too small. Its size of dozens of kilometers makes this earth-shaking feat a weird farce.

The earth, water, wind and fire in this world are simply unable to support the birth of top-level Heaven and Earth Qi. Even the upper Heaven and Earth Qi is difficult to touch. It can only give birth to four middle-level Heaven and Earth Qi.

Fortunately, Shen Yuan never had much hope for this secret realm of dozens of kilometers in radius. He guided the birth of the Qi of heaven and earth only to better sort out the earth, water, wind and fire.

The clearly defined areas before his eyes were the changes brought about by Shen Yuan's control of the Qi of heaven and earth with his Nine Breaths supernatural power.

Although everything was just the beggar's version of creation, the ability to hold the rules in one's hands and modify them at will to create this world still gave Shen Yuan great inspiration.

Faintly, Shen Yuan's Nine Breaths to Subdue the Qi magical power that had been stagnant for a long time showed signs of improvement.

Looking at the desolate world where the earth, water, wind and fire had already been determined, Shen Yuan let out a long sigh, and a trace of fatigue flashed in his eyes. Three days of constantly guiding the fusion of Yuan Qi consumed a lot of Shen Yuan's energy.

If it weren't for the natural spirit pool in the secret realm of the courtyard that constantly replenished his magic power, and the awakening light of the starry bodhi tree that cleared his mind, Shen Yuan might not have been able to hold on.

"Anyway, the prototype of the secret realm has finally been successfully established. Now all we need is an opportunity."

As his thoughts flowed, Shen Yuan slowly stretched out his right hand.

On his palm, the Xuanhuang Qi and the Qingyuan Xuanzhen Qi were intertwined.

One contains the power of mountains and is as heavy as the earth; the other breeds the pure and empty spirit like the sky.

These two streams of heaven and earth qi are exactly the clear and turbid qi chosen by Shen Yuan.

The Xuanhuang Qi represents not only the power of the earth, but also carries the source of vitality of all things in the Xuanhuang world. It is the root of the mother energy of all things.

As for the Qingyuan Xuanzhen Qi, it came from the Xiaoyou Qingxu Heaven, and its roots can even be traced back to the thirty-six heavens in the upper realm, with some of the Dongtian Dao remaining.

Shen Yuan exhaled lightly, and the clear and turbid air quickly merged into the secret realm behind the black hole.

A yellow-brown color began to emerge on the barren black land, and the rhythm of the earth and the foundation of life began to emerge from the originally dead silence.

And above the Qi of the Heaven and Earth of the Silent Burning Wheel that spread throughout the sky, the Qingyuan Xuanzhen Qi resides above the nine heavens and transforms into a light blue sky that covers this world. Spiritual energy and air are constantly born from under the sky.

The world was settled. Shen Yuan in the secret courtyard stood up and walked towards the deep black hole.

The space changed, and the next moment Shen Yuan appeared in the Fang Cun Secret Realm.

As the creator of Fang Cun Secret Realm, Shen Yuan could clearly sense that the Fang Cun Secret Realm now already had the initial conditions to accommodate living beings.

It may not be capable of being used as a small world, but it is fully qualified as a secret place.

“But it’s still a little short.”

As the thought moved slightly, Shen Yuan exhaled a wisp of cold air from his mouth.

That ray of icy breath appeared between heaven and earth, and quickly turned into a bright full moon rising into the sky, occupying an area of ​​the sky.

The cold moonlight shines down, bringing with it a bone-chilling chill; it is the end of the year and the weather is cold.

The moon has returned to its place. Normally, Shen Yuan should have inspired Zhu Ming Chengye to transform into the sun and completely complete the Fang Cun Secret Realm.

However, compared to Zhu Ming Chengye, who was only at the middle level of Heaven and Earth Qi, Shen Yuan at this moment already had a better choice.

"Come!"

A soft command came from Shen Yuan's mouth.

The courtyard outside the Fang Cun Secret Realm trembled slightly. The next moment, countless starlight under the projection of the Starry Sky Bodhi in the courtyard turned into celestial stars and descended into the Fang Cun Secret Realm.

And at the top of the secret courtyard, a shining golden sun was gradually dimming amid the tremors.

The dim part of the light was diverted by an invisible giant hand and merged into the secret realm of the courtyard. A bright sun appeared in the small secret realm.

The earth, water, wind and fire have been determined, the clear and turbid air divide the heaven and the earth, the sun, the moon and the stars have returned to their positions. The Fang Cun Secret Realm has been almost perfected to the limit at this moment, and even ordinary caves cannot compare with it.

If the previous Fangcun Secret Realm only had the potential to become a small world at the creation of the world, then the Fangcun Secret Realm at this moment, except for its limited size, is already a real small world.

Especially the big sun above the sky is a projection from the sun itself. It is not something that can be transformed by simple magical powers. It is no less powerful than the big sun in all realms.

Under this round of projection of the sun star, countless great rules will evolve and gradually perfect this small world.

“Finally done!”

Bathed in the sunshine, Shen Yuan let out a long sigh, his expression somewhat excited.

Although many tricks were used to create a secret realm comparable to a small world, it is undeniable that this is beyond the reach of ordinary people in the lower world.

Even the immortals from the upper realm who have studied this art in depth can mostly only evolve cave paradises, and very few can open up a small world.

His eyes scanned the environment within the Fangcun Secret Realm, and the end of the Fangcun Secret Realm could be clearly seen in the distant sky.

"The only flaw seems to be that it's too small."

As the thought moved, bursts of roars came from the originally barren land, and mountains rose from the ground, covering the sky and earth as far as the eye could see.

A large amount of water mist rose from the ocean, covering the boundary between heaven and earth.

As the creator of the Fangcun Secret Realm, the third-level Hutian supernatural power can manipulate space at will.

Under Shen Yuan's interference, the originally orderly space became chaotic, and any step could trigger the space channel and be teleported to other places.

The space above the sky was blocked, and the whistling tornado transformed from the Burning Wheel of Annihilation disturbed the strong wind layer, restricting all living beings from flying into the sky.

Whether it is blocking the boundary between heaven and earth or prohibiting flying, it is all to prevent the practitioners who have stepped into the secret realm from noticing the smallness of the secret realm.

As for the chaotic space channel transmission, it was Shen Yuan's way of increasing the difficulty of the subsequent secret realm trials.

Otherwise, with the strength of a cultivator, even in a no-fly zone, he can still easily explore an area of ​​dozens of kilometers without any interference.

After doing all this, Shen Yuan stopped what he was doing.

“The general framework of the secret realm has been built, and the next step is to deal with some details.

For example, the form of the secret realm trial, how to design the trial levels, and even how to provide rewards to the trial participants are all within the scope of subsequent consideration. "

Shen Yuan whispered to himself, with stars twinkling in his eyes, and thoughts gradually rose from the bottom of his heart.

"But compared to these details that can be made up later, there is something more important."

"The rules of this world are incomplete, and it can only accommodate the arrival of the Divine Transformation cultivators. In this case, how can I lead the Divine Refining Immortals from the major cave heavens and blessed lands to the secret realm for trials?"
