"This person has a very powerful long sword. Can the palace have detailed information about this sword? What kind of martial arts does this person practice?" Liu Yu came back to his senses and asked. The sword moves that Li Chenqi used in the secret realm were extremely domineering. The golden light of the sword in his hand lingered, and the sword energy was scattered like a dragon soaring into the sky, leaving a deep impression on Liu Yu.

"There is no news that this palace cannot find out about this Dongyuan Realm. The sword of this son is called "Golden Dragon Breaking Armor Sword". It is a fourth-grade high-level spiritual weapon. It is made by the master of refining the mysterious iron outside the sky and melted the best tungsten gold. The gold-cutting jade is extremely sharp, and it is a fine sword. The skill he practiced is the "Eight Desolate Dragon-Slaying Technique" of the Great Wilderness Sword Sect. The sword moves to split mountains and cut off water, and it is extremely powerful." The old man said leisurely.

Liu Yu's face suddenly looked like dark clouds. He knew that Li Chen would be very angry, but he didn't expect that he would be so strong. If he encountered it, whether he could survive the two or three moves was unknown. His heart was extremely solemn, as if he was pressed under a mountain, and he couldn't breathe.

"Where is this person now?" Liu Yu was silent for a moment and continued to ask.

"This guy, I went to Qingfeng City with his master "Tie Wuqing" a while ago. He should have gone to explore the "Black Haze Blood Land". Now he has returned to the "Great Wilderness Rift Valley" located in the Great Wilderness Sword Sect to practice hard and prepare for "building the foundation". The old man chuckled and replied.

"Will this person "build the foundation" in the near future?" Liu Yu immediately asked. If Li Chen's foundation is successfully built, his situation would become more dangerous.

"With this son's spiritual root qualifications, it's only a matter of time before and after, but fellow Taoists have thought it apart. This son will not "build the foundation" in the near future. It should be four or five years later." The old man picked up the tea and said confidently.

"This person's cultivation has reached great perfection and his qualifications are excellent. Why don't he "build the foundation" as soon as possible?" Liu Yu frowned and asked in confusion.

The old man took a sip of tea and smiled and said, "It is because of this that I am extremely talented and I am not in a hurry to open up the "Purple Mansion". This man is practicing the secret method "Yuantian Xuan Jing" to break through the "Danxin Acupoint", and open up a larger "Purple Mansion" space in one fell swoop and improve his own cultivation level."

"The "Yuantian Xuan Jing"? Is it the supreme foundation-building secret technique that only those prides of heaven are qualified to practice?" Liu Yu's face changed and he blurted out and asked.

"That's right! The purple mist hides the fields and builds the Tao forever, which is about this "Yuantian Xuan Jing"." The old man sighed and replied.

"So that's it!" Liu Yu couldn't help but whisper to himself. If Li Chen had practiced the "Yuantian Xuan Jing", it would indeed be a significant delay in the "foundation building" time. With his talent, he should also choose to practice the "Yuantian Xuan Jing".

"Yuantian Xuan Jing" is a high-level earth-class mental method. It is very famous in the world of cultivation and is called the "Purple Misty Climbing the Sky" secret method by many cultivators in the Qi-Practice Cultivation Period. When the cultivators who practice the "Yuantian Xuan Jing" will be filled with rich "Purple Misty True Qi" in their dantian. At this time, they will open the mansion to "build the foundation" and will benefit greatly.

This sutra is extremely harsh. It not only requires a lot of spiritual power to be consumed during practice, but also requires extremely expensive "special spiritual liquid" to assist in the practice. In this way, the "purple mist true energy" can be nurtured bit by bit in the dantian, which can be said to be both time-consuming and wealth-consuming.

But why the "Yuantian Xuan Jing" is still so popular among the monks in the Qi training stage? This also starts with the cultivators breaking through the bottleneck of the Danxin acupoint and opening up the "Purple Mansion" of the Taoist foundation. The "Purple Mansion" is a unique space formed by the cultivators refining the Danxin acupoint. The space is in a closed spherical shape that spreads from the inside to the outside.

The "Zifu" space capacity that the cultivator breaks through the Danxin acupoint and successfully refines the foundation of the "Zifu" varies from person to person. The specific capacity is generally equivalent to the size of an ordinary room, and is called "Yifu". The specific capacity of the "Zifu" is related to the qualifications of the cultivator.

For some cultivators whose meridians are pure and whose bottlenecks are weak, the "Purple Mansion" space formed by the foundation building will be much larger, reaching "one and half" or "two mansions".

Some prides of heaven who possess the "Tao Body" form will have a larger space of "Purple Mansions" and can reach the "Three Mansions" or "Four Mansions".

The larger the "Purple Mansion" space formed by the cultivator after the foundation building is successful, the more spiritual energy it will accommodate, and the stronger the combat power it will be. In other words, the higher the cultivation level. For this reason, measuring the cultivation level and strength of the cultivator in the foundation building stage depends on the specific size of the "Purple Mansion" space of the cultivator himself and how much spiritual energy it can accommodate.

The process of cultivators in the foundation-building stage cultivation is the process of absorbing, consuming the five elements of spiritual energy, transforming, impacting, and expanding the "Purple Palace" space.

"Purple Mansion" is a different space opened by cultivators. Cultivators need to continuously consume spiritual energy to consolidate the stability of this different space, and consume a large amount of spiritual energy to impact the invisible space barrier, expand the size of the "Purple Mansion" space, and improve their own cultivation.

As we all know, the definition of the strength of the foundation-building cultivators in the cultivation world is divided into the first, middle and last three stages. The size of the "Purple Mansion" space from "one mansion" to "five mansions" is for the early stage of foundation-building, the "six mansions" and "seven mansions" are for the middle stage of foundation-building. The "eight mansions" and "nine mansions" are for the late stage of foundation-building.

The "Purple Moon True Qi" nurtured by practicing the "Yuantian Xuan Jing" has the effect of instantly expanding the size of the "Zifu" space. Those who practice the "Yuantian Xuan Jing" will have the "Zifu" space formed after the foundation is successful than those who have not practiced.

Those gifted "Tao Body" owners can reach the "four palaces" or even the "five palaces" after practicing the "Yuantian Xuan Jing" after building the foundation. After consolidating their cultivation, they will soon be able to break through to the middle stage of foundation building.

This shows the mystery of the "Yuantian Xuan Jing". No wonder it is regarded as the supreme foundation-building secret method, and its effect is indeed too despicable.

At this time, some young men who had just entered the Taoist path and lacked knowledge would ask, why not practice the "Yuantian Xuan Sutra" after successfully building the foundation?

This is the strange thing about this sutra. The "Yuantian Xuan Jing" is only effective in the Qi training period. When practitioners of the Foundation Establishment period practice this sutra, the dantian cannot produce a trace of "purple mist true qi", which is deeply regretful.

At this time, someone will raise doubts. Even if a cultivator in the Foundation Establishment Stage cannot practice this "Yuantian Xuan Jing", can he practice other techniques to expand the "Purple Palace" space? Isn't it more practical to practice this "Yuantian Xuan Jing" when practicing Qi Great Perfection?

This has to mention the speed of cultivation progress of the foundation-building cultivator. A two-spirit foundation-building cultivator absorbs energy and practices normally. It took about fifty years to expand the space of the "Yi Mansion". Even the Tianling Root cannot be much faster, and the cultivation level is extremely slow.

On the other hand, when those who practice the "Yuantian Xuan Sutra" have sufficient resources for their own cultivation, a cultivator in the Tianling Root Qi Practice Period can only take about ten years to cultivate this sutra to great success. With the absurd effects of this sutra, the space of the "Yi Mansion" can be at least improved after successful foundation building.

This is why the "Yuantian Xuan Jing" has become so famous in the world of cultivation and is desirable.

Although the "Yuantian Xuan Sutra" has such a despicable effect, only a few people will truly consider practicing this sutra. It is not because this sutra is so mysterious or too cherished and difficult to see. In fact, all major sects of the "Yuantian Xuan Sutra" are open to their disciples. As long as they are determined to practice, it is not difficult to obtain the practice of this sutra.

The "Yuantian Xuan Jing" can only be practiced after the great perfection of Qi training. In addition to the long time of practice, the cost of cultivation is also extremely scary.

The "special spiritual liquid" taken to practice this sutra is made up of "Purple Whisper Ginseng", Rehmannia and Dew True Water that have been used for more than five hundred years. If you want to practice this sutra to great success, you must prepare at least millions of low-level spiritual stones.

The "Yuantian Xuan Jing" is considered to be the supreme foundation-building secret method that only a few prides of heaven are qualified to practice.

In addition to the excessive cost of cultivation, there is another main reason, that is, the "Purple Moon True Qi" hits the bottleneck of the "Danxin Acupoint" and goes to seclusion for foundation building, not only does it have any benefits, but it will block the operation of spiritual power and greatly enhance the difficulty of "building foundation".

Only after the bottleneck of the "Danxin Acupoint" is broken through, the "Purple Moon True Qi" will play a despicable effect, instantly integrate into the newly opened "Purple Mansion" and quickly expand the size of the "Purple Mansion" space. This is the fundamental reason why the "Yuantian Xuan Jing" is only suitable for those with superior qualifications to practice.

For those who are mediocre in qualifications like Liu Yu, the bottleneck of the "Danxin Acupoint" is tough. Whether they can "build the foundation" is a big problem. How dare they practice the "Yuantian Xuan Jing"? Besides, there are not so many spirit stones, and there is no time to practice the "Yuantian Xuan Jing".

In short, the "Yuantian Xuan Jing" is destined to be qualified to practice, which makes countless cultivators feel sad and helpless!
