In fact, before that, Ling Yun always understood his shortcomings. It's just that limited to the mission world experienced and the limited plane that opens the item trading authority, and the resources that can be obtained are insufficient, so I haven't been able to find a suitable reference material.

Ling Yun's own original "Secret Book of the Heavens" is now missing the exercises on spiritual power cultivation, and can only be regarded as a half-finished exercise.

Among the many cultivation secret methods that he had been able to come into contact with before, the "Earth-level Maha Immeasurable" in the Wind and Rain World was the highest.

But even if it is "Ground-level Maha Immeasurable", it is only the demon lord who reverses from "Primary-level Maha Immeasurable", and the relief is still a set of martial arts secrets, and when it comes to achievements in spiritual power, it is still not professional enough.

However, "Cutting the Sky and Drawing the Sword Technique" is completely different, as the strongest ghost path cultivation method in the world of "A Chinese Ghost Story", it already has a unique advantage in terms of spiritual power cultivation.

It is important to know that the ghost in the so-called ghost path is a kind of virtual body that has lost its physical body and is purely composed of spiritual energy. The exercises established on this basis are, of course, based on the cultivation of spiritual power.

Even in some immortal planes, there are also similar to ghost immortals, scattered immortals, etc., and the existence of recultivating the physical body by spiritual energy or primordial divine energy, which shows the power of their cultivation exercises.

However, although the "Heaven Slashing Sword Technique" was strong, Ling Yun only used it as a reference, and did not directly cultivate according to the above records. Because the founder of this set of exercises blindly sought the power of the exercises after falling in love overnight, he added many methods to the exercises in order to seek speed and enhance power, and added many methods to absorb yin and evil qi, so that this set of exercises was pushed to the devil's path.

This can be said to be contrary to Ling Yun's original vision of the quality and quantity of Dancun's spiritual power, if you want to use it for your own use, you must first analyze and deduce it thoroughly, and then choose the parts that are beneficial and harmless to you, and integrate them into your own "Secret Book of the Heavens" before cultivating.

However, this is easier said than done, but in practice it is far from being as simple as it seems. Even though Ling Yun himself had an extraordinary comprehension and was assisted by the various functions of the Heavenly Office, it still took half a year to complete the work of stripping the exercises.

Then comes the more cumbersome second step. Reintegrate and unify the remnants of the exercises that were previously stripped from the "Heaven Cutting Sword Technique", combine what you have learned, and thoroughly integrate it into the "Secret Book of the Heavens".

In order to complete this step, Ling Yun not only spent three years, but even ate the Soul Fruit to increase his perception of spiritual energy. Of course, in the past three years, two of them have been spent in the Spirit Time House, which can not only buy him more time, but also make his spirit more impactful and the deduction effect stronger under the pressure of the external environment.

It wasn't until three years had passed that Ling Yun had finally finished sorting out the spiritual power cultivation part of the Heavenly Secret Texts to form an independent set of cultivation methods.

According to the cultivation method, Ling Yun's spiritual power was able to skyrocket in a short period of time, which not only quickly made up for his shortcomings in spiritual power, but also made his reincarnation eye be promoted again. Although his appearance has not changed, through the evaluation of Dawn, it is known that his current pupil power is no weaker than that of Kaguya Ji back then, and he has completely obtained the reincarnation eye state of the Nine Hook Jade!

It was a good thing that his strength had skyrocketed, but Ling Yun was not satisfied with his current cultivation results. Because, the solid foundation part of the "Secret Book of the Heavens" is still missing the crucial last step, which is to perfectly integrate spiritual energy and physical strength, so that one's own power is completely integrated and flawless.

This step is undoubtedly more difficult. Ling Yun integrated what he had learned before, and spent another 10,000 points of origin energy to deduce it in the Spirit Time House for a whole year, but after all, there were still some crucial links, and the use could not achieve the expected effect.

Therefore, he spent another 100,000 points of origin energy to buy a top exercise in the world of "The Legend of Sword and Fairy", "Shushan Sword Codex", and through the energy of his own inexplicable sword technique, he made every effort to deduce.

Sure enough, the hard work paid off, and in the end, Ling Yun finally found an opportunity to deduce the "Secret Book of the Heavens" to a perfect realm in this immortal cultivation technique. However, the exercises have become more and more intensive, which also means that the threshold for cultivation has become higher, and with Ling Yun's current physical and spiritual strength, it is not enough to complete the last step of solid foundation cultivation.

In desperation, Ling Yun could only smash out the little source energy he had left, almost all of which he had in one go.

First, he purchased another characteristic building that can assist in cultivation, Ten Thousand Swords Reincarnation.

Reincarnation of Ten Thousand Swords: The Sword Sect's unique mechanism secret room, hidden inside, there is also a 'Sword Wheel' mechanism embedded with ten thousand sharp swords, as long as it is activated, the Sword Wheel will run on its own. Every day, ten thousand sword intent is shot to attack the cultivator, and the cultivator not only cannot have the slightest defense, but also takes the initiative to meet the strongest killing target of the sword intent in order to achieve the best cultivation effect.

Price: 20,000 points of Origin Energy.

Under the sword intent of 10,000 sword moves, under the 10,000 different kinds of pain and crazy torture, if the cultivator naturally does not collapse, it can naturally promote the rapid improvement of physical strength and skill.

It can be said that the reincarnation of ten thousand swords is definitely a cultivation path that is close to self-harm. And unlike the magic balm of the Spirit Time House, the reincarnation of ten thousand swords is only applicable to sword cultivation, and it must be the sword cultivation of the Sword Sect of the "Fengyun" World.

Because the foundation of cultivation in the reincarnation of ten thousand swords is to be proficient in the ten thousand different sword moves of the sword sect's foundation.

Fortunately, the quality of the things produced by the system is absolutely guaranteed, and it comes with incomparably valuable experience, plus Lingyun itself has the "Inexplicable Sword Technique", an evolutionary plug-in cheating weapon, which can master it all in a short period of time, and quickly plunge into the reincarnation of ten thousand swords, polishing his physical strength.

In the middle of half a year, when Ling Yun finally felt that his physical strength had been qualitatively improved again, he turned around again, entered the Spirit Time House, and began to further hone his spiritual power that was so strong that he could form a primordial spirit at any time.

So far, he has worked hard for several task worlds, and it can even be said that the hundreds of thousands of Origin Soul energy accumulated by saving money has been completely consumed, leaving only a pitiful evil 3123 points!

It was really hard work for more than ten years, and once it returned to the pre-liberation period.
