Ye Li, who was in a trance, quickly understood that the two rune arrays should have yang runes on one side and yin runes on the other.
He didn't know why he suddenly saw these two rune arrays. Before his doubts disappeared, the purple color in front of him suddenly became more intense.
The two rune formations that were originally far apart were suddenly pulled closer to him.
The spiritual energy from the eighteen runes in the two formations continued to flow and change in the two rune formations, and all of this was clearly displayed in front of Ye Li's eyes.
As the spiritual energy continued to flow, Ye Li carefully watched the changes in the trajectory of each rune in the two rune formations.
The more Ye Li looked at it, the more he could feel the mystery of the two rune formations. He could not remember most of the runes at all, and only a small part of the outlines and trajectories could be recorded by him.
As he continued to observe, he discovered that there were actually only two types of runes in the two rune arrays.
In the Yang Rune Array, the nine runes are exactly the same, and the same is true for the Yin Rune Array.
However, the trajectory of each of the nine identical runes seemed to change slightly as the spiritual energy flowed through them, and they were not exactly the same.
Moreover, each rune seems to have no starting point. The strokes within the rune are completely connected to form a cyclical whole. After the spiritual energy enters it, no matter where it starts from is the starting point, and no matter where it leaves is the end point.
Ye Li could only think of one rune with such special properties, and that was the rune of origin of attributes.
He didn't know about this characteristic of the attribute origin rune in the past, but Ou Qianxie mentioned it when he was explaining the basics of casting to him.
Ye Li observed the operation of the two types of origin rune formations, and he seemed to have gained something in his heart. The outlines of the two formations were gradually imprinted deeply in his mind.
And as he observed the Yang Origin Rune, he vaguely discovered that some of the tracks contained in this rune were somewhat similar to his Fire Origin Rune.
Feeling the similarities in the trajectories, Ye Li's mind was completely attracted and he began to comprehend unconsciously.
At the same time, next to his natal talisman, in the area of the fire talisman root, the number of fire talisman characters began to increase.
He already had four complete Fire talismans, and the fifth Fire talisman also had a stroke.
And now, new strokes began to appear on the fifth fire symbol. The second, third, fourth...
Lines of symbols began to appear clearly next to the fire symbol, and his understanding of the origin of the fire element actually began to strengthen again.
Tunri naturally noticed his changes. Although it didn't know why Ye Li strengthened his Fire Root, it knew that it was probably because of the two purple lights that shot out from Ye Li's eyes.
The purple thick paste in Ye Li's sea of consciousness was rapidly decreasing at an extremely alarming speed. Even though his natal talisman was still constantly absorbing spiritual energy and producing new purple mist, it could not keep up with his consumption speed.
After only about an incense stick of time, the thick purple liquid in Ye Li's sea of consciousness was completely consumed, leaving only the thin purple mist continuously spit out by his natal talisman.
The two purple beams of light in his eyes disappeared, and Ye Li felt himself being pulled out of the strange illusion space in an instant. His consciousness returned to himself, and the scene in the Great Yin-Yang Casting Furnace appeared in front of him again.
"I... I'm still alive!?"
After a moment of confusion, Ye Li suddenly remembered his previous experience and spoke with a look of astonishment on his face.
Tunri was sure that Ye Li had really woken up, and immediately said with a smile: "Ye Li, you are awake, it seems that you have survived this crisis, and you have gained a lot.
You must be prepared, you are about to break through to the Spiritual Pill Stage!"
Tunri’s words shocked Ye Li even more, and he hurriedly checked his physical condition.
It would have been better if he hadn't looked at it. Once he looked, his eyes immediately widened.
He found that his Dantian was half as large as before, and it felt as if it was about to touch a critical barrier.
He knew that his realm had already risen to the late stage of the Spirit Sea period, and the barrier he was about to touch was obviously the edge of the Spirit Pill period.
He wanted to move his hands and feet a little. The spiritual swamp that enveloped him was still there, but the amount had been reduced by more than half.
Moreover, his hands and feet were able to overcome the obstacles brought by the spiritual swamp and move around inside it.
This means that his physical strength is much greater than before, and the power of the spiritual swamp can no longer restrict his movements.
What surprised him most was the vortex of spiritual energy in the middle of his forehead. The surrounding swamp-like spiritual energy was being rapidly devoured by his natal talisman, and finally transformed into his own spiritual energy, which accumulated and compressed while resisting the pressure from the outside world.
Ye Li gave his body a comprehensive examination and found that it was just as Tunri said, he was now close to the peak of the Linghai stage and might soon break through to the Lingdan stage.
"Senior Tunri, I...what happened to me? Could it be that my natal talisman saved me?"
Ye Li opened his mouth and asked about Tunri's arrival.
Tunri nodded, then took a look at Ye Li's natal talisman and said, "You are so lucky, your natal talisman is really an incredible thing, it saved you at your most critical moment.
It swallows all the spiritual energy around you that is absorbed by the Great Yin-Yang Sky-Forging Furnace and used as raw material for refining the Sky-Forging Spiritual Paste.
I really didn't expect that you could absorb such a terrifying amount of spiritual energy so easily.
With the help of these spiritual energies, the spiritual energy in your body becomes more and more, successfully resisting the squeezing and grinding of the yin and yang energies.
There is still a lot of spiritual energy left here, which should be enough for you to break through later.
And look at the spiritual essence in your dantian. After being cleansed by the chaotic power in the Zhutian Spiritual Paste, it has become somewhat crystal clear and has also been tainted with a hint of chaotic attributes.
If nothing unexpected happens, I believe that after you break through, you will definitely be able to condense a divine elixir!"
At the end of the speech, an extremely excited expression appeared on Tunri's face, as if it was about to make a breakthrough.
This is not surprising. After all, it and Ye Li are now in a master-servant relationship. The stronger Ye Li is, the better it is for it.
After listening to Tunri's explanation, Ye Li immediately focused his attention on his dantian. It was indeed as Tunri said, his spiritual energy had completely turned into a translucent crystal white color.
Moreover, his originally ordinary spiritual energy now contained a very mysterious and strange aura that people could not understand at all. This should be the chaotic aura that Tunri mentioned.
