"There is really no verifiable evidence for this legend! There has never been any evidence to prove the existence of the underworld." he paused, and the red tower continued. From his tone, Qin Feng heard an uneasiness he had never felt before.

"In that very remote era, there were some legends about the underground mansion. It seemed that the underground mansion really existed, but I didn't know what happened in the end. It seemed that the remote era was faulted with later generations, resulting in no substantive records. But later generations speculated that the underground mansion might be related to the sky crack."

"There are strong people looking for us in this vein, but no one knows the result." Hongta said, and his tone gradually became extremely heavy: "and there is likely to be Huang quandan here, which also proves that the person in our vein has succeeded. No wonder that there is a strange disappearance and did not participate in the last war."

"Whatever is related to the underground mansion, it is difficult to come to a good end in the end." said Hongta again: "of course, what I said is only limited to legends. It is difficult to investigate whether the underground mansion was really there. After all, in our time, we have never heard of any evidentiary events in the underground mansion."

"Huangquandan is the heart of the underground. This statement is somewhat unreliable, but the former one is more true. It is only formed by the power of the earth's Yin and evil spirits, which has nothing to do with the underground."

Qin Feng's heart was hard to calm for a long time. Although what he said were legends, it sounded too penetrating.

The underground mansion is the gathering place of countless ghosts. It's numbing to think about it. What's more, it sounded an alarm for him. Those just related to the underground mansion will come to no good end. He directly took away the heart of the underground mansion, not his life.

"It's really seeping, but now that I've come to this step, I've settled today, whether it's the gathering of the earth or the heart of the yellow spring related to the underground."

With that, Qin Feng directly put away the defense of Yang Qi and let those Yin and cold forces invade his body. And his body is also slowly falling, absorbing more yin and cold power.

Although the Yin cold power here is far better than the ordinary Yin cold energy, Qin Feng's body has absorbed a lot before and has some resistance, so it can't cause much trouble for him. At most, it makes him cold.

The body was descending at a constant speed in the boundless darkness, and the surrounding Yin cold force eroded and wandered back and forth in his body. The Yin cold force was distributed, which was enough to freeze ordinary people into ice,

The more he went down, the more terrible the Yin cold force became. Qin Feng also suffered a little, but he was slowly adapting to the Yin cold force here.

Dong!

The subtle sound came out. Qin Feng felt that the soles of his feet stepped on the real object, and his look gradually became solemn. Looks like it's over.

He looked out. The light here was not as bright as before, but it was very dim and extremely depressed.

His eyes glanced back and forth around him. Suddenly, his eyes suddenly paused. After a long time, a radian slowly hung around the corner of his mouth.

"Huangquandan, I found you."

In that dark place, there was a place where the black was extremely strong and almost became liquid. The strong Yin and cold force directly formed a light ice film around.

In the center, there is a black bead about the size of an adult's fist suspended, which should be said to be a round pill, because it is solid.

In the round pill, there seems to be a black liquid wriggling, but in the center, it is not black, but a kind of similar white, like a touch of white light, illuminating the darkness here.

"Is that the yellow spring pill? The most Yin thing?" Qin Feng's face was gradually replaced by ecstasy. After absorbing its Yin and cold power, he could arrange the yin-yang fusion array and practice the yin-yang art.

Qin Feng quickly went there. As the distance approached, the heat in his eyes became more and more intense.

Hiss!

The palm of his hand was gently attached to the ice film. Suddenly, the ice film as weak as paper was broken in an instant. At the same time, an extremely terrible cold suddenly hit him. The cold was so cold that he couldn't help taking a breath.

With the breaking of the ice film, the force of yin and cold contained in it, which had nowhere to release, came to Qin wind and shrouded it. The cold current surged. The force of yin and cold penetrated into his body along the pores.

As soon as the cold entered the body, Qin Feng's body suddenly tightened up, as if it was going to be frozen.

"What now? Break it?" Qin Feng asked with great pain.

"Wrap it directly with psychic power and suck it into the body."

Qin Feng felt numb when he heard the speech: "suck it into the body? Are you kidding? I can only resist this thing now, and this is not the purest Yin cold force. If I suck it into the body, I won't freeze me directly into ice?"

"Huang Quandan is the power of the earth. After thousands of years of compression, it can not be broken. Otherwise, it will lead to the passage of the essence. Only when it is put into the body, can it produce the most perfect Yin Qi, so as to stimulate the most pure Yin force in your body." Hongta Sansheng road.

"Yang Qi has condensed in your body. Although it can't be compared with the Yin Qi of Huang quandan, as long as you can bear it, there should be no big problem. Don't forget, you still have the formula of fire god!"

In the eyes of Qin Feng, his eyes are also passing through a ruthless color. Even if there is another big danger, he can not let Huang Quandan's essence pass away. Every step of Yin Yang's technique must be perfect and flawless.

Thinking of this, the cruel color in his eyes gradually turned into madness. Then he took a move with the palm of his hand, trained and shot out, wrapped Huang quandan, and then began to compress.

Under the compression of Lingli, Huang quandan gradually reduced to the size of an ordinary pill, but the color became more and more rich, which made people feel frightened.

Huang quandan slowly suspended in the palm and felt the terrible cold on it. Qin Feng swallowed his saliva. A moment later, his eyes coagulated fiercely and opened his mouth to inhale Huang quandan into his body.

Boom!

A slight sound broke Huang quandan, and a large area of strong black energy completely shrouded Qin wind like a tide. A black cold current was drilling into his body.

Boom!

The sharp pain also surged into Qin Feng's heart like a tide at the moment. The indescribable cold directly made the blood in his body coagulate. Fortunately, he was prepared and urged by his mind to resist the biting cold atmosphere.

The light spot at the center of Huang Quan Dan is the most essential part of Yin cold. After the explosion of Huang Quan Dan, the spot of light suddenly follows the throat of Qin Feng, just like the cold ice passing through him, and enters his body.

Boom!

At the same time, an extremely terrible cold breath suddenly penetrated into the body from the mouth, and then rippled in all parts and bones.
