Because when it first leaves the cultivator's body, the "Nensha Core" is delicate and fragile, and the light undoubtedly carries energy. Very weak light will cause damage to the "Ninsha Core".

For the delicate and fragile nature of the "Ninsha core", it is actually very easy to understand.

For example, a ghost body is transformed from the soul of a person whose physical body has lost its vitality, and a soul that has not undergone cultivation will quickly dissipate after leaving the body.

Even if there are ghost bodies with cultivation, when their cultivation is still low, the sunshine that everyone likes is like a thousand arrows to their ghost bodies, and it is a big killing weapon that makes them dissipate in the air.

In the quiet room, if incense is lit that has the effect of calming the mind and calming the mind, it will be beneficial for the "Nensha Core" to float in the air when it is separated from the body.

The two will attract each other, the aroma can wrap the "sand core", to provide it with a thin layer of protection, the aroma of the soul-rejuvenating ingredients will seep into the "sand core", help the "sand core", so it can improve the success rate of the nucleus and the quality of the sand.

Before entering the meditation room, Chen De specially bathed and changed his clothes to show his respectful and solemn heart, and in the meditation room, he lit the best sandalwood incense.

In the cultivation retreat room, it was pure darkness, and it was silent, only the faint fragrance lingered.

At this time, under Chen De's mental power "gaze", the first Niansha rune array rose from the jade bottle, and suddenly, in the originally completely dark cultivation quiet room, there was a light like fireflies on a summer night, which was the spiritual light on the rune array.

The Niansha Rune Array floated quietly a foot in front of Chen De's eyes, and with the help of Sandalwood Incense, Chen De quickly entered the realm of emptiness and selflessness.

At the acupoint of Chen Deyintang, under the operation of the mental method of the Thousand Thoughts of Vientiane Technique, it was first hot, and then outside the Yintang acupoint, there was also a light that lit up, which was a grain of "Nian Sand Core" that had just floated out of the acupoint.

Without a pause, Chen De's two hands each formed a mudra.

And these two mudras are different from each other, and they have to be formed at the same time.

This is a smaller level of the Thousand Visions, which requires the monk to be able to use two things without the slightest mistake.

But Chen De has long been able to use two minds, and can even draw different runes with his left and right hands at the same time. Chen De had tried, naturally, only limited to simple runes.

The handprint of the left hand is driven by the sand rune array, and the handprint of the right hand is driven by the "sand core".

At the same time, the muscles and peritoneum of Chen De's chest and abdomen, under the obscure rhythm, cooperated with each other and drummed together, and let out three incantations.

With the cooperation of the mudra and the mantra, the Niansha Rune Array and the "Niansha Core" were close to each other, and just when the two were about to touch each other, the Niansha Rune Array seemed to be under the action of a strange force, and after an obvious shaking on the surface, a small vortex appeared.

The vortex is not big, and it appears on the already small Nensha Talisman Array, so this vortex is small.

But in this small whirlpool, it has its own peculiar suction, and the "Niansha Core" is very obedient to this suction, and under the traction of this special suction, the "Niansha Core" falls to the ground, passes through the whirlpool, and returns to the center of the Niansha Rune Array in the blink of an eye.

The moment the "Niansha Core" entered the center of the Niansha Rune Array, the "Niansha Core" was immediately closely connected to all aspects of the Rune Array.

Originally, as soon as the "Nian Sand Core" left the Yintang Acupoint, Chen De felt a sense of pain from the "Nian Sand Core" that was pricked by needles all the time, which was the erosion of the Heaven and Earth Yuan Qi in the quiet room on the "Nian Sand Core".

Now this restless pain is gone.

The feeling that came from the "Nensha Core" immediately changed, it was a comfortable feeling, as if lying in a warm, soft quilt on a cold winter day.

At this point, Chen De's first grain of sand was completed.

Chen De couldn't help but let out a long breath.

After calming down, Chen De remembered what kind of scene and what kind of feeling he would feel when he tried to run the induction method of the Thousand Thoughts and Myriad Phenomena Technique.

A few hundred words of induction flowed through Chen De's heart.

For this part of the Thousand Thoughts and Myriad Techniques, Chen Deyin operated for the first time, and the circulation and handling of spiritual energy and the coordination of divine soul and mental power were quite sluggish.

At the same time, the spiritual power of the soul is in the brain palace, corresponding to the meridians and acupoints when the aura is running, and the corresponding starry sky is visualized.

In addition, when visualizing the corresponding starry sky phase, the mouth and nose cooperate with the chest and abdomen to make a mantra sound. The frequency of this spell sound is lower than the frequency that can be heard by the human ear, so this spell sound that matches the starry sky law phase is silent in human ears, but there are some demon beasts that are sensitive to it, but it can be heard.

For the practice of the induction method, Chen De put a lot of effort into it, and then he knew that the mastery of this mental method was actually a level of this thousand thoughts and all kinds of techniques.

Chen De could also imagine how Senior Brother Lu used to look like he was scratching his ears and cheeks when he was studying this Thousand Thoughts Technique.

Because the incantation sound is silent, you can only rely on telekinesis to capture its vibrational effect on the air, and in the absence of experience, you don't know whether it is correct or not, and how far away it is from the accurate vibration method.

Moreover, the flow of aura, the visualization of the starry sky by the spiritual power, and the mantra must be coordinated with each other, so as to achieve the accurate operation of the mental method.

The difficulty can be imagined!

And this starry sky is the law of the three walls and four images.

The Dharma of Sanyuan is Ziweiyuan Xingguan, Taiweiyuan Xingguan, and Tianshi Xingguan.

The four elephants are the image of the green dragon in the east, the image of the red bird in the south, the image of the white tiger in the west, and the image of the Xuanwu in the north.

Cultivators are all too familiar with the Dharma of the Three Walls and Four Elephants.

Moreover, in the cultivation realm, there is a saying that all exercises involving the stars are quite difficult and profound, either the power and utility are amazing, or the weather is grand and bright, which can best declare the meteorology of the immortals, and the practical effect is average.

The comprehension and mastery of the induction method of the Thousand Thoughts and Myriad Techniques is another torture and test for Chen De.

After transporting the mental method hundreds of times, Chen De only felt that his divine soul power and Niansha's qi induction had increased, but there was no other movement.

However, Chen De thought of the pain of soul splitting, the difficulty of comprehending the talisman array, and this time the comprehension of the induction method of the Thousand Thoughts and Myriad Techniques, and the torture and test of the mastery process, were just a small mountain that was slightly difficult to climb after climbing a few mountains.

Therefore, after experiencing 8*900 ineffective mental movements, Chen De still did not have the slightest discouragement.

He was still energetic and constantly groping for this very complex, rather irritating method of induction.

In this grinding process, Chen De became more and more familiar with the meridians of the reiki circulation, and at the same time, he transformed the corresponding starry sky phase to be visualized, and in the process of the aura's circulation, the cooperation between the two became more and more proficient.

It's just that the activation of the incantation and the cooperation between the first two are still clumsy, and Chen De has always been unsure of how to accurately issue this incantation.

Because, after these eight * nine hundred attempts, none of them succeeded, so there has never been a correct ruler for judging the spell sound.

It was the memory of how to pronounce the mantra text, and he had memorized it backwards.

Chen De also has a deeper understanding of how to make accurate mantras, how to drive the movement and shaking of the muscles and tendons in the chest, abdomen, mouth and nose, but unfortunately there is no correct reference.

After more than a thousand failed attempts, Chen De faced his only Nian Sha at the moment, only to feel that his divine soul was becoming more and more connected to its qi.

He didn't have the heart to let the other two "Nian Sand Cores" return to the Nian Sand Talisman Array, so he let them still be kept warm in his Upper Star Cave.

After hundreds of attempts, Chen De estimated that it was close to two thousand, and still none of them were able to successfully perform the Thousand Thoughts Technique.

He also knew that the problem was the accuracy of the spell sound.

Because, the mantra sound in the induction mind method is more than five or six times more complicated than the mantra sound issued when the "chanting sand core" is put in place.

Chen De thought to himself, he had also encountered the disadvantages of his own exploration, and if someone pointed out, it was estimated that he would have succeeded.

However, going to someone for guidance was a move to reveal his hole cards and automatically apply to become a research sample for high-level monks.

Thinking of the guidance and reference, Chen De felt that he was alone in the quiet room, like a brute bull, just relying on the momentum of not giving up, bravely moving forward, or recklessly trying. This way does seem a bit stupid.

At the same time, I was stuffed in the quiet room, making nearly 2,000 failed attempts, and I was doing it behind closed doors.

Chen De naturally thought of it, isn't there a silent gentleman in the sect? That is, those rich and diverse classics in the Classics Pavilion.

With this in mind, he did not hesitate, stepped out of the cultivation retreat room, and walked towards the Classics Pavilion with a pace that was neither fast nor slow.

The exercises of the Tiantai sect are not known for witchcraft, and only a small part of the exercises should be created by borrowing from witchcraft, or even born out of witchcraft, and there is a process of casting or reciting mantras when casting spells.

In addition, after the accumulation of many generations of sect monks, the Tiantai sect has a lot of expositions and classics related to witchcraft and incantations, which are of course equivalent to other types of exercises, and these discourses and classics are much less.

Chen De, who came with questions, was in a relatively relaxed mood.

In the Classics Pavilion, the popularity is more popular than other parts of the sect. There are especially many young monks here.

Because the young monks have a lot of knowledge of cultivation, such as their understanding of a wide variety of demon beasts, spirit grasses, and elixirs, their understanding of the four arts of cultivating the true nature of the Instrument Array Dan Fu, etc., and even when cultivating exercises and spells, they can sometimes seek a solution to the symptoms here.
