As the ape spirit expected, the further down he digged, the more gray energy contained in the stone would be, and the more refined it became. In the end, even Ao Fan felt that gray energy.

Fortunately, this gray energy seems to be relatively mild in nature, and it is not like the death qi outside, which will forcibly enter the body. As long as you don't touch it, it won't enter the body.

After digging for nearly a kilometer, there was a sudden collapse below, and another passage appeared.

Ape Spirit and Ao Fan hurriedly entered, and found that it was a tunnel, and the place where they appeared was just above the tunnel.

There was no dead air in the tunnel, it was so quiet that you couldn't even feel the movement of air.

The appearance of the ape spirit and Ao Fan could not break the dead silence here, and with the vision of the ape spirit, he could not see everything around him clearly, as if he had come to the world of "nothing".

An uneasiness began to creep through the hearts of the ape spirit and Ao Fan, and although they tried to get themselves back to the bottleneck, the more they tried to suppress this feeling, the faster the uneasiness grew.

Ao Fan took a deep breath, tried to calm himself, and said, "This place is so scary. Just entering it already made me feel uneasy. It's hard for me to imagine going crazy if I stayed here for a long time. ”

The ape spirit also said, "That's right. It's the first time I've been to this kind of place, and my senses are even reduced to a minimum. ”

Ao Fan glanced at the pitch-black front and asked, "Is there really a Yin Stone in this place?"

The ape spirit shook his head and said, "I don't know. But I think we'd better get out of here as soon as possible. Otherwise, I don't really know how long I'll be able to stay awake. ”

Using the power of yin and yang, a cluster of flames ignited in front of him, illuminating everything around him, although the visibility was still less than ten meters, it still made Ao Fan and the ape spirit feel a lot more comfortable.

The ape spirit and Ao Fan chose a direction to move forward, and at the beginning, the ape spirit also flew against the wall, wanting to see if there was a better Yin Yin Stone. However, after flying for nearly two hundred kilometers, he did not find a single Yin Yin Stone, which made him feel strange in his heart, and at the same time felt that he seemed to sigh a little too much. I knew that I would have just collected some Stygian Stones.

Ao Fan stopped and said, "It's not a way for us to keep moving forward like this. There should be no Stylistic Stone in this place. I think we'd better go back. ”

The ape spirit hesitated for a moment, he had a feeling since entering this tunnel, this place was not simple, at least this feeling of "nothing" was not something that could appear casually. There must be a secret somewhere in this tunnel that they don't know.

Of course, Ao Fan also knew this, but the longer he stayed here, the more intense the uneasiness in his heart became, and now he was even a little panicked.

After all, the ape spirit is a realm higher than Ao Fan, and the lord who has been able to restrain himself so far glanced at the seemingly endless tunnels ahead, and finally decided to move forward for a while, and if he still found nothing, he decided to leave.

Hearing the ape spirit's thoughts, Ao Fan took a deep breath and nodded, "Okay." We're digging a little deeper. ”

Seeing that Ao Fan seemed to be working hard, the ape spirit stopped talking nonsense and hurried away.

This time the ape spirit gave up on finding the Stygian Stone, which was no longer his ultimate goal, he just wanted to see what was at the end of this tunnel.

At this moment, the speed of their flight increased greatly, and soon they flew nearly thousands of kilometers, and there was still nothing on the way, but this oppressive feeling became stronger and stronger, and the flame in their chests shrank from the size of a watermelon to the size of a fist, as if it was about to be extinguished.

Just when the ape spirit was about to lose it anymore and decided to give up, he was finally able to see a hole that seemed to appear in front of him.

This hole boosted the morale of Ao Fan and the ape spirit, and they all increased their speed to the fastest, and they passed through the cave in an instant.

However, they were a little disappointed to find that it was just an ordinary cave and didn't seem to have anything special.

The ape spirit was a little disappointed and said, "Are we looking in the wrong direction?"

Ao Fan didn't expect this kind of result, he was lost in his heart, and after staying in this kind of place for a long time, it seemed that he could maximize the negative emotions, Ao Fan actually yelled at the ape spirit, "I said I left a long time ago, you didn't listen, now it's okay, I didn't find anything, so I ran for nothing." Don't think that you really think that you are blessed with some good things before, how can there be so many good things in the world for you to get?"

The ape spirit was also a little irritable at the moment, seeing Ao Fan yelling at himself, he just wanted to fight back, but he suddenly endured it, and began to observe the cave instead.

Ao Fan was even more annoyed when he saw that the ape spirit was unmoved, and roared angrily, "Are you deaf or don't take me seriously at all......?"

Without waiting for Ao Fan to finish speaking, the ape spirit said loudly, "Ao Fan, restrain yourself, don't be affected by your negative emotions." ”

One sentence was like a slap in the face, which made Ao Fan sober up instantly, and said secretly, "What's wrong with you, how can you yell at the ape spirit for such a trivial matter?"

Ao Fan tried to calm himself down, came to the ape spirit, and said apologetically, "Ape spirit, just ......"

The ape spirit smiled reluctantly and said, "Don't take it personally. This place is really weird, we must keep our minds and not let our negative emotions affect us. ”

Ao Fan nodded and said, "I'll pay attention." By the way, did you find anything?"

The ape spirit has used his natural supernatural powers to start searching for this place, and finally even the variety has been released, hoping to use the ability of the variety to detect treasures to find out if there are any good things here.

However, Bai Chang sensed it for a while and found nothing, and said to the ape spirit, "Master, there should be no good things in this place, because I don't feel any treasure at all. ”

Hearing this, the ape spirit was even more disappointed, but he still thought that he was lucky, and did not let his clone stop, but continued to search every corner of the cave.

A sense of irritability appeared in Ao Fan's heart again, but with the experience of the past, he restrained his emotions this time and tried to calm himself down, but the consequence of this was that his mind was extremely draining, even if he felt a little tired.

Almost every inch of the cave was turned over, and nothing was found, and the ape spirit finally gave up, and it was almost certain that there was no treasure in this place at all.

The ape spirit glanced at Ao Fan, who looked tired, apologized in his heart, and stepped forward and said, "You're right, it's impossible for all good things to be mine." It's me who is too willful, let's leave now. ”

Just as the ape spirit wanted to leave with Ao Fan, a stone flew out and was suspended in front of the ape spirit, which was the stone that sealed the great ancient beast, and after such a long time, the ape spirit almost forgot about this stone.

The stone had appeared, and the bull crocodile couldn't wait to fly out, but its body was small, only slapped, and it was not as huge as when I first saw the ape spirit.

The ape spirit looked at the bull crocodile and asked, "Senior, who are you?"

The bull crocodile ignored him, but walked around the cave, as if to determine something.

Finally, the crocodile shouted, "Old guys, come out for me, the little guy has really found something amazing this time." ”

As soon as these words came out, the light like fireflies flew out of the stones, turned into their original forms, and began to fly around the cave.

It was the first time for Ao Fan to see these souls, and he asked with some curiosity, "Who are they?"

The ape spirit gave a brief introduction, and Ao Fan learned that these were the existences of the Great Ancient Era, and looked at these small and delicate existences in amazement.

The bull crocodile came up to the ape spirit and asked, "Little one, how did you find out here?"

The ape spirit explained the cause and effect, and finally asked, "Senior, what is there in this place?"

The bull crocodile did not answer, but looked at Ao Fan and asked in a deep voice, "Who is this guy?"

Ao Fan stepped forward and saluted, "Junior Ao Fan, meet the seniors." ”

The bull crocodile was a little surprised, and said, "Your surname is Ao, are you a dragon?"

Ao Fan nodded and said, "The junior is the dragon clan. ”

Only then did the bull crocodile relax his vigilance and said, "Since it is a dragon clan, it should be trusted." If I'm guessing correctly, this place should have a sunstone. ”

Ape Spirit and Ao Fan glanced at each other, neither of them had heard of this thing, and said with some doubts, "Senior, I have heard of the Yin Stone, but I have not heard of the Yin Stone." What is the Stygian Stone?"

Bull crocodile explained, "The Pluto Stone is actually a derivative of the Pluto Stone, the extremes of things must be reversed, when the energy in the Pluto Stone reaches saturation, it will undergo a qualitative change, and it will be transformed from negative energy to positive energy, and each Pluto Stone will need a huge amount of positive energy when it is formed, so the area where it is located will become a dead silence, leaving only negative energy, in this kind of place will make the negative emotions expand infinitely, if the guy who is not firm will soon go crazy." ”

Only then did the ape spirit and Ao Fan suddenly realize, and Ao Fan even understood the reason why he was so irritable just now.

The ape spirit continued to ask, "And what is the purpose of that sunstone?"

"The body of the Stygian Stone is the Stygian Stone, but it has positive energy, which means that a stone contains both positive and negative energy, and there are too many places where it can be used. For example, if you refine a treasure and incorporate the Stygian Sunstone, then that treasure will have two extreme energies at the same time, just like the power of yin and yang. When you invest in refining the elixir, you can also refine the elixir that directly allows the soul body to grow into the flesh. These are only part of the utility of the Stygian Stone, and you say that this thing is good or not. ”

It was the first time that the ape spirit had heard that the materials that could be used for refining could also be used for alchemy, but this also fully illustrated how rare this dark sun stone was.

The other demon clans also came to the side of the bull crocodile and congratulated the ape spirit, but it seems that their appearance is not just to tell the ape spirit that there is a dark sun stone in this place.

The ape spirit looked at them with expectant eyes, and what the bull crocodile said just now suddenly flashed through his mind, and he suddenly realized, "Do the seniors want me to help you reshape your physical body?"

The bull crocodile smiled and said, "You kid is still very smart, and he hit the nail on the head at once." I just don't know if you're willing to help us with this?"

The ape spirit smiled bitterly, "I don't know how to do alchemy. And I don't have a Dan Fang, how can I help you rebuild your body?"

At this time, the demon clan next to the bull crocodile stepped forward and said, "Danfang, don't worry, I know how to refine the pill, and now the question is whether you are willing to help." After all, the Sunstone is yours, and you already know how precious it is. Are you reluctant to use it for alchemy?"

The ape spirit has never been a miser, since the Stygian Sun Stone can help these great ancient beings reshape their bodies, it is still very cost-effective for him, after all, these predecessors are alive, and the Stygian Stone is dead. How can something that is dead be more important than something that is alive.

Without hesitation, the ape spirit agreed, "No problem. It's just that I've been looking for a long time and haven't found the so-called Plutomy Stone. I also hope that the seniors can help me find it. ”

As soon as they heard that the ape spirit promised to reshape their bodies, these old guys who didn't know how many years they had lived cheered one after another, and the bull crocodile took the lead and said, "Don't worry, our group of guys will help you find out the Stygian Stone." After saying that, he rushed over first. Since it has no form, it suddenly enters the wall and disappears.

Not to be outdone, the other demon clans scattered one after another and began to look for the Stygian Stone.
