In the real world, Su Xing saw this and nodded slightly.

"The seventeenth level of the formation is indeed worth an immersive simulation..."

"If I continue to use the simulated exchange for enlightenment, not only will it be a waste of time, but it will also be expensive..."

"A hundred years of immersive simulation should be enough for me to upgrade my formation to level seventeen!"

Thinking of this, Su Xing silently said:

"Using an immersive simulation, lasting 100 years..."

[Ding... Remaining energy source 1,164,456 points...]

The prompt sounded, and the awakened consciousness entered the simulated world.

…

In Luotian Realm, Su Xing held up a thick ancient book in his hand, which was a detailed explanation of the Tianji Formation written by the master of Tianji Pavilion.

Su Xing only roughly flipped through a part of it, and he was quite touched: "In the world of formations, if the Master of Tianji Pavilion is second, I'm afraid no one dares to claim to be first..."

Su Xing was already a sixteenth-rank grandmaster of formations, but just based on the insights written by the master of Tianji Pavilion in this ancient book, he was deeply moved after reading it.

It can be seen that there is still a huge gap between Su Xing's formation skills and the level of Tianji Pavilion Master.

"Then, let's officially begin to comprehend the Dao of Formations!"

Su Xing makes a cup of enlightenment tea and starts to gain enlightenment in a transcendent state.

He took out many materials for setting up the formation, and while setting up the formation, he comprehended the detailed explanation of the formation left by the Master of Tianji Pavilion.

In this way, thirty-six years passed in the blink of an eye.

…

That day, Su Xing took out the materials for setting up the formation that he had prepared in advance, and with a wave of his hand, a giant breath-suppressing formation that was big enough to cover an entire city appeared.

"The fifteenth-level Tianyuan Breath-Retaining Formation can be set up in just a few breaths..."

"In the past thirty-six years, my understanding of the Dao of Formations has greatly improved... but it seems that I am still some distance away from setting up a seventeenth-level spirit gathering formation."

Su Xing shook his head slightly.

In the past thirty-six years, Su Xing has used about two cups of enlightenment tea.

Taking into account the blessings of enlightenment tea, great wisdom appearing foolish, late bloomer, etc., Su Xing's enlightenment in one year is equivalent to that of an ordinary cultivator in two thousand years.

Thirty-six years is equivalent to seventy-two thousand years of comprehending the art of formations.

Even so, Su Xing was still one step away from setting up the seventeenth-level spirit gathering array.

"It is true that the further you go in the world, the more difficult it becomes... This one step away can stop countless cultivators from practicing hard!"

"Fortunately, for me, everything that requires time to accumulate is not difficult..."

At the moment, he still has two cups of enlightenment tea, ten Wen Dao pills, and an accidental enlightenment.

With enough trump cards, Su Xing is fully capable of improving himself to the level of a 17th-rank formation grandmaster.

Thinking so, Su Xing brewed a new pot of enlightenment tea and began to meditate.

…

When the century-long immersive simulation ended, Su Xing returned to reality.

Recalling the memories in his mind, Su Xing nodded slightly and said with satisfaction:

"The Grandmaster of Arrays has finally reached the level of setting up a seventeenth-order spirit gathering array!"

Su Xing's mind moved, and he waved his hand, and the magic pen and talisman ink that he had prepared in advance waved in the air.

Immediately afterwards, a palm-sized miniature spirit gathering array appeared in Su Xing's palm.

"Ninth-order micro-spirit gathering array... I also mastered it during the process of comprehension..."

After replacing the original micro spirit gathering array with the newly arranged ninth-order micro spirit gathering array, Su Xing clearly felt that the speed at which he absorbed spiritual energy had increased a lot.

"Yes, the cultivation speed has increased by about 50%... Now all that is left is to successfully arrange the Great Cave Heaven, and the cultivation in the future Golden Immortal Stage will be smooth!"

Su Xing is used to preparing for a rainy day. Although he doesn't have enough energy now, it is only temporary. It is always right to prepare what is needed for practice in advance.

"The goal of this simulation has been successfully achieved. In the next period of time, I will plant some more Spirit Gathering Flowers and try the layout of the Great Cave Heaven again!"

Su Xing thought so and looked at the simulation panel.

[In the 350th year, you came out of Luotian Realm.]

[A hundred years of immersive simulation in Luotian, but only three years have passed in the outside world...]

[Next, you will plant the Soul Gathering Flowers in Luotian Territory and prepare to raise funds for the layout of the Great Cave Heaven.]

[Another fifty years have passed...]

[In the 400th year, the number of Spiritual Gathering Flowers in your Spiritual Field Cave has exceeded one million.]

[Although the number is huge, it is still not enough to advance to the Great Cave Heaven. ]

[So for the next hundred years, you continued to cultivate the Soul Gathering Flower.]

[In the 500th year, the number of spirit flowers in your Lingtian Cave has reached three million! ]

[Three million Spirit Gathering Flowers may sound like a lot, but for a spiritual field with a radius of 8,000 miles, being able to maintain the spiritual energy of a blessed land for the entire world is already very good.]

[So next, you began to arrange the spiritual field cave, and chose a valley with a radius of ten miles to build it as your own cave. ]

[From the layout of the cave's feng shui to the range of the spirit gathering array, you built it all by yourself, trying to ensure that there is enough spiritual energy inside the cave.]

[You planted millions of soul-gathering flowers around this cave valley, and under the guidance of the soul-gathering array, gathered the spiritual energy born from the soul-gathering flowers.]

[You used the power of space to move a mountain a hundred feet high, and dug ditches and planted spiritual plants.]

[Under the effect of the water gathering formation, a mountain stream filled with spiritual fluid slowly flows down from the top of the mountain...]

[Inside the valley, you opened up a pond specifically for the Spiritual Vein Dragon. After thousands of years of recovery, the Spiritual Vein Dragon's injuries have long since healed, and it is continuously releasing spiritual energy.]

[The quality of the cave has been further improved...]

[In this way, after a hundred years of hard work, you finally created a perfect cave that suits you best.]

[From the weapon refining room, the alchemy room to the formation room, the places with abundant spiritual energy are specially used for cultivation. ]

[This cave can provide you with tens of thousands of drops of top-grade spiritual fluid every day...]

[However, after waiting for a long time, as the spiritual energy in the cave gradually increased, no immortal liquid was produced. ]

In the real world, Su Xing frowned slightly when he saw this.

"How could this be? No immortal liquid has been produced yet... This means that the cave is still at the level of the best cave... and still has not reached the level of the great cave!"

“Even if more top-grade spiritual fluids are produced, without the birth of immortal fluid, there will be no qualitative change…”

Su Xing carefully recalled what he had done in the simulation and the layout of the cave, trying to see if there was anything he had missed.

But no matter how Su Xing deduced, he had done his best.

"Could it be that in this world... the Great Cave Heaven really cannot be born?"

Su Xing couldn't accept it.

Putting aside other things, the three million Spirit Gathering Flowers are something that no other force in this world can produce except Su Xing.

"Perhaps, there is something crucial missing?"

"No, it seems I have to go to the Tianji Pavilion to find the answer..."

Su Xing felt that it might not be so easy for the Great Cave Heaven to produce the immortal liquid, and it was not something that could be achieved by simply accumulating spiritual energy.

Maybe there will be records in the Tianji Pavilion about the principles of the formation of the Great Cave Heaven.

Thinking so, Su Xing looked at the simulation panel.

[In order to find out the principle of the birth of the Great Cave Heaven, you go to the Tianji Pavilion to search. ]

[After paying a contribution point, you enter the Sutra Library in the Tianji Pavilion, which is also the most comprehensive treasure house of ancient books, skills, etc. in the entire Three Thousand Worlds. ]

[You searched for a long time in this Sutra Library and finally found a way to build the Great Cave Heaven.]

[The Great Cave Heaven was born naturally. To build it artificially, in addition to having a sufficient supply of spiritual energy, the most important thing is to have a treasure that can suppress this cave heaven. ]

[At least, it also requires a top-grade innate spiritual treasure as the core of the cave to suppress it before it can be built. ]

[This may be as difficult as ascending to heaven for other monks, but for you, it is extremely easy.]

[You return to the Lingtian Cave Heaven and silently awaken the Luotian Mirror in your body, and then use a projection of the Luotian Mirror to place it in the cave valley.]

[Under the suppression of the Chaos Supreme Treasure's projection, the entire cave residence underwent earth-shaking changes in just a short moment.]

[As if it was injected into the core, the entire cave began to operate crazily. ]

[The spiritual energy in the air has become several times denser, visible to the naked eye. The entire cave within a radius of ten miles makes the cultivators feel extremely comfortable, like a fairyland on earth.]

[You finally understand what the Great Cave Heaven is... This is definitely the cave that every cultivator, even immortal, dreams of.]

[In this large cave, you can feel that your cultivation speed has increased by several times. ]

[At the same time, the water gathering array in the cave will produce thousands of drops of tempting immortal liquid every day.]

[The energy contained in this immortal liquid is a hundred times greater than that of the best spiritual liquid, and it is easier to absorb, and has great benefits for immortals. ]

[Just take a thousand drops of the immortal liquid, and you will recover most of the mana you originally consumed. This immortal liquid is not only an excellent holy medicine for cultivation, but also a treasure for restoring mana in battle. ]

[So far, you have the cave for cultivation that even the Golden Immortals dream of in this era - the Great Cave Heaven! ]

In the real world, Su Xing saw this and a look of excitement flashed in his eyes.

"So that's how it is. It needs to be suppressed by a supreme treasure in order to create a complete Great Cave Heaven..."

Su Xing blinked, it really was effortless.

Even if it is a top-grade innate treasure, its suppression effect may not be as good as the projection effect of the Luotian Mirror, right? After all, although innate treasures are rare in the world, there are still a few hundred of them.

As for Chaos Treasures like the Luo Tianjing Mirror, there are only three of them in the entire Three Thousand Worlds.

What excites Su Xing the most is the increase in the speed of cultivation brought by the Great Cave Heaven.

"In the Great Cave Heaven, the spiritual energy is more than ten times that of the Top-grade Cave Heaven... The speed of cultivation will also be increased several times."

"And if we produce a thousand drops of immortal liquid every day, the effect of one drop of immortal liquid is at least equivalent to a hundred drops of top-grade spiritual liquid... that means the daily output is 100,000 top-grade spiritual liquids!"

As soon as Su Xing thought of this, he shook his head slightly.

The preciousness of the immortal liquid is far beyond that of the top-grade spiritual liquid.

The immortal liquid is easier to absorb and its spiritual energy is pure. A Golden Immortal cultivator can absorb it directly and easily transform it into his own cultivation and magic power.

If it is spiritual liquid, even if it is much purer than ordinary spiritual energy and spiritual stones, it is inevitable that there will be impurities. Even if the Golden Immortal uses the best spiritual liquid to practice, the impurities still need to be removed.

In this way, practice will not be so easy.

Therefore, even in ancient times, let alone exchanging a hundred drops of top-grade spiritual liquid for a drop of immortal liquid, there might not be any cultivator willing to exchange even a thousand drops.

It is equivalent to that spirit stone is similar to spirit liquid.

"What's more, in this era... the number of places in the entire Three Thousand Worlds where immortal liquid can be produced is probably no more than a handful, right?"

"Even some Golden Immortals may not have the means to produce Immortal Liquid..."

After a pause, Su Xing continued, "Now that the Immortal Liquid and the Great Cave Heaven have been successfully completed... it's time to test the speed of cultivation!"

Su Xing wanted to see how long it would take to make progress in the Golden Immortal Stage at his current speed of practice.

Look at the simulation panel.

[In the 500th year, you successfully built a cave dwelling of the Great Cave Heaven level in Lingtian Cave Heaven, which is what the Daluo Jinxian dreams of.]

[For the next hundred years, you will practice in seclusion in the Great Cave Heaven. With the help of the Zhengyi Fuqi Jue, your cultivation will advance by leaps and bounds.]

[With every day of practice, you can feel the accumulation of your own magical power. ]

[If you used to fill your own sea of ​​​​qi with a bucket of water, then now, every time you practice, you use a bucket to fill your sea of ​​​​qi, and the efficiency is more than increased several times. 】

[However, the power of the Golden Immortal is so deep and bottomless that it is extremely difficult to make progress.]

[For a Golden Immortal, breaking through a small realm in tens of thousands of years is already considered an extremely fast speed. ]

[If there is no blessing of a fortuitous encounter or natural treasures, even a hundred thousand years may not be enough to break through. ]

[But practicing in the Great Cave Heaven, coupled with your own spiritual roots, your cultivation aptitude has long been among the best in the world. ]

[In just two hundred years, you have reached the threshold of the middle stage of the first level of the Golden Immortal.]

[In the 700th year, while you were cultivating your magic power, you also cultivated the range of your spiritual domain to 9,500 miles, which is very close to the Ten Thousand Miles Spiritual Domain.]

[You know that you don’t have much time left to practice, so you work harder to improve your magic power. ]

[And so, another hundred years passed...]

[In the eighth hundredth year, on a peaceful afternoon, after circulating your Zhou Tian magic power once, your cultivation successfully broke through to the middle stage of the first level of the Golden Immortal.]

[In just three hundred years, you have made a small breakthrough in your cultivation. ]

[In the same year, the range of your spiritual realm was increased to 9,900 miles... The distance reached 10,000 miles, and you were only one step away from being promoted to the spiritual realm.]

In the real world, Su Xing saw this and nodded with satisfaction.

"In three hundred years, from the early stage of the first level of Golden Immortal to the middle stage of the first level of Golden Immortal, this speed is definitely not slow!"

"What's more, this is without the blessing of the gold-level late bloomer... If it is blessed, it can even achieve a small breakthrough within two hundred years."

"From the first level of Golden Immortal to the second level of Golden Immortal, it will probably only take six or seven hundred years..."

"This cultivation speed is even three times faster than when I was a Xuanxian!"

Compared to the speed at which ordinary Golden Immortals break through a realm once every 50,000 or 100,000 years, a simulation of awakening can basically guarantee more than one breakthrough in cultivation, which is already astonishing.

"There is also the Spirit Realm, and the breakthrough is not far away..."

"Then let's try to comprehend the spirit world in this simulation!"

Su Xing's mouth curled up. He still remembered that the Mirror of Nothingness in the Tianji Pavilion still had a chance to improve its strength...
