Demon Dan floated from the palm of Tang Feng's hand to the air in front of him.

Tang Feng took out a few jade runes and put a simple array around the demon pill. Then he used aura to urge the array.

Several jade runes immediately radiate light, interweave into a void network, and envelop the demon Dan in it.

On the surface of the demon Dan, the black fog began to linger. At the beginning, the fog was very thin, very light, almost transparent, and gradually diverged towards the light of jade symbol weaving. The color became more and more thick, and began to gather together.

This kind of situation is similar to the time when the spirit was coagulated. However, at that time, the fog condensed to the spirit from the outside to the inside. This time, it was from the inside to the outside, and it continued to spread out, which made the demon pill look several times larger.

But although the black air on the demon Dan became more and more thick, when it touched the light emitted from the jade amulet, it suddenly became a little lighter. When it came out of the light, it was almost gray.

This kind of appearance is like the golden net formed by the jade rune, which has the function of filtering out the strong evil spirit in the black fog. This time, it is quite similar to what Tang Feng did when he subdued the evil spirit. He also used the jade Rune to absorb the evil spirit from the evil spirit layer by layer, and finally condensed into a demon pill.

The spirit itself, however, no longer exists.

Looking at the gray fog, Tang Feng didn't seem very satisfied. He laid a few jade amulets outside the circle, which still formed a net of light. But this time, the shape of the net was much finer than before.

When the gray fog came out of this layer of light net, the color was completely pure white. It lingered around the jade amulet and tossed up and down. It was like a sea of clouds when it was picked up like that. On the demon Dan, it was still emitting black fog, which was filtered into the white layer by layer. The whole hall was like a fairyland.

Seeing the pure white fog, Tang Feng nodded with satisfaction, and his mouth also showed a faint smile.

Although the white fog is not Aura now, it is still evil spirit, and the evil spirit can be absorbed by people. Of course, it is only the cultivation of Tang Feng that can directly absorb the evil spirit. If you are someone else, you will still cause irreparable damage to your body. Therefore, Tang Feng will set a ban in this hall.

After all, he intends to release all the evil spirit. Even if the evil spirit becomes pure after the baptism of his array, it is still very dangerous for ordinary people.

This is the demon pill of ten thousand year old monster. Its performance in the cave in the mountain seems not so strong, but that's because it is surrounded by restricted array. In addition, it has just been awakened, and its ability has not been restored. If it is such a demon in the peak state, Tang Feng can't deal with it so easily, or even can't deal with it.

Even if he exhausted all his strength and took away the spirit, he would pay a considerable price.

This time, Tang Feng's luck was excellent. He did not spend much effort to get rid of the spirit. However, the spirit left behind was much more powerful than the energy it showed. This way, the whole city of Xizhou would not be able to bear it, let alone the people close at hand.

Tang Feng saw that the fog was almost all around him, and then he sat on the ground with his knees crossed.

The lobby of this suite is quite spacious, sitting on the ground, and there are no obstructing furniture around, which is more convenient for him to move.

Tang Feng took a deep breath, and saw the fog around him suddenly gathered towards his body, and then quickly rushed into his body along his seven orifices, and formed a few white lines, which were still flowing into his body, as if Tang Feng's body had a strong suction, you can inhale them.

Although Tang Feng is absorbing the fog at a very fast speed, the air in the hall has not changed at all.

The demon Dan in the jade Rune array is still emitting the black fog. After two layers of golden net of jade rune, it is also pouring out, which just fills those absorbed by Tang Feng and fills the whole room again.

Tang Feng didn't pay attention to the demon Dan. Instead, he inhaled the pure demon Qi that had been filtered into his body. The aura that gathered in his body immediately came up and gathered with the demon Qi. The light green aura and the white aura merged together. After that, the color of the aura gradually weakened and became pale, close to transparent, Light green again.

Not long after, these demons have been completely transformed into the same color as Reiki, and completely integrated.

The transformed evil Qi immediately moves along the meridians in the body, and finally enters the Dantian and precipitates.

The sleeping yuan Shen seems to feel something when the transformed aura enters the surroundings. In an instant, his body trembles, then opens his mouth and greedily absorbs the aura transformed from the surroundings.

Yes, at the moment, the evil spirit has been completely transformed into aura in Tang Feng's body, which can be directly absorbed by the yuan Shen to repair his own damage. There is no difference with the real aura.

Now on this earth, Tang Feng is the only one who can do this.

For others, under the invasion of such strong evil spirit, they would have reported to Jiuyou underworld for a long time. I'm afraid that now, they have already passed the Naihe bridge, and they can't tell if they start drinking Mengpo soup.

However, even Tang Feng did this by relying on the strength of his physical body. Before the magic realm was fully restored, he did not dare to absorb the evil spirit too fast, but controlled it within the speed he could control. Fortunately, the speed he could control was not slower than that of the demon pill, so that he could keep in the hall all the time, Evil will not overflow.

Before the change, Tang Feng would not take the risk to transform the evil spirit with his own body. But now, this is Tang Feng's best choice, especially to get such a rare ten thousand year demon pill. If he doesn't use it, it really makes Tang Feng feel that it's a bit outrageous.
