As a prescription for the eight-rank pill that is difficult to find in the world, in exchange for a quota that can enter the Dan realm every year to collect medicine, this is naturally an extremely cost-effective exchange, Dan Xuan has no refusal, and there is no reason to refuse.

So naturally, Su Yu became a guest of the Dan family without exception, and then obtained a place to enter the Dan realm once.

The entrance to the Dan Realm is in the center of the inner domain of Shengdan City, and compared to the outer domain, the defense of this inner domain is also more severe, but on the contrary, there are more alchemists who have stepped into this inner domain to stay, and of course, in comparison, its strength is also unmatched by those outer alchemists.

With the guidance of the Dan family, Su Yu passed through the city gate of the inner region very smoothly, and the first thing that caught his eye was the extremely huge Baizhang Black Tower in the center.

This huge black tower is as black as ink, standing silently between heaven and earth, there is an indescribable awe, like a towering and steep mountain, heavy above everyone, it looks particularly mysterious, and it is difficult to violate.

Su Yu, who was in the distance, could vaguely feel the huge and abundant aura in it.

For these alchemists who came to enter the Dan Realm because of the quota, the people of Danta did not block too much, and following the arrangement of the Danta personnel, they entered a special passage.

As his line of sight cleared, Su Yu found that his position was still not the majestic Dan Pagoda before, but had become a vast mountain range, and it was obvious that this was still not the world before.

Although it was different from another world, in it, Su Yu still felt the faint strong aura hidden in the depths of the mountains.

However, Su Yu didn't pay too much attention to those domineering aura, after all, the purpose of his coming this time was only to target the alien fire.

The figure swept into the air, and the huge soul power also began to sweep across this piece of heaven and earth, looking for this extraordinary aura.

After a few days, Su Yuxuan's actions not only did not come to fruition, but fell into the eyes of some people.

At this time, in a majestic hall on the top floor of the Dan Tower, an old man dressed in white stood in front of the bright window, looking at the endless churning sea of clouds.

The old man's eyes were calm, like a pool of tranquility without waves.

It's just that suddenly, his eyes are like a stone thrown into a calm lake, faintly fluctuating, and his eyelids are slightly raised, and the sea of clouds outside the window in front of him sets off a wave.

His eyes glanced to one side, on the jade that was as clean as a mirror.

This jade table is the size, and the surface is so bright that there is no trace of carving, but it is extremely miraculous that the picture displayed on the surface of the jade actually reflects the situation that happened in the Dan Realm.

"I haven't looked for a single medicinal herb for five days, it seems that the medicine is fake, and the fire is real!"

At this time, the old man had already turned his head and looked at the young figure shown on the screen, with a smile in his unfathomable eyes.

He was one of the three giants of the Dan Tower, Xuankong Zi, and he naturally knew what else was in this Dan Realm besides medicinal materials.

"Well, the peak of the Dou Zong, the strength is good,"

Consciousness flowed out, feeling the breath of the young man, the old man nodded slightly, but then, a trace of surprise swept over his face full of deep Zhou Wen.

"The soul power is okay, well, there are still those ancient bloodlines, but there is no weird feeling of the soul clan, it seems that it is the people of the other six clans, since this is the case, then give you a chance to see if you can accept it......"

The distant voice echoed in the empty hall, and the old man chuckled, and his withered and thin palm was raised and hung above the jade.

In a moment, there were wisps of strange power that smeared into the jade, and the turbid Dan Realm sky fluctuated slightly, and suddenly there were a few more fine cracks.

And in the eyes of Su Yu in the Dan realm, there are also these few more slits.

Looking at the spatial crack that suddenly appeared in front of him, Su Yu stopped the surprise in his heart, his eyes swept over the surrounding environment, and the huge soul power was also swept away.

However, nothing was found, and these strange cracks seemed to appear in front of him by chance.

Stabilizing his mind, when Su Yu's soul consciousness extended through those cracks, he found an extraordinary aura, this aura was like a huge wave of fire, although there was only one wisp, but it carried an extremely huge amount of heat.

In an instant, Su Yu's face pale slightly.

In this space, what else can have this kind of scorching energy, I'm afraid the only thing is the huge three thousand Yan flames.

He had found nothing for so long before, and now through this crevice that had quietly appeared, it seemed that these three thousand Yan flames were not in the Dan Realm at all, but in another space.

Although he had doubts about the crack that suddenly appeared, Su Yu still did not hesitate.

The majestic power of space surged out from the palm of his hand, stretching out the space that could only pass through one arm, so a desolation, filled with a faint hot mist, appeared in Su Yu's eyes.

Looking at the space that was completely different from the breath of the Dan Realm, Su Yu took a deep breath, and then stepped out step by step steadily.

In an instant, the environment was completely different, all I saw was a desolate sandy field, and there was an extremely hot wave of air in my face, as if I was in a huge furnace.

After Su Yu stepped into this world, the crack in the space behind him also suddenly disappeared without a trace.

For such a situation, Su Yu didn't think much about it, feeling the direction of the heat wave flow in the air, just thinking about the source of the heat wave flying out.

A few minutes later, a scorching and dazzling strong light that people couldn't look at directly also appeared in Su Yu's eyes, and when his eyes adjusted, he could see a giant dragon winding like a mountain range entrenched in the desolate land in front of him, the huge dragon's eyes were closed tightly, and purple-black strange flames were swirling around the purple dragon scales, as if burning in the void.

This sleeping dragon is naturally the manifestation of the three thousand flames, but it is only a phantom manifestation, but it carries the power of the dragon like a substance.

For the Three Thousand Yan Flames in such a state, it is not an ordinary difficulty to surrender, it is just what Su Yu thinks, just try it, if you can't, then it is okay to contact the origin of the Three Thousand Yan Flames and open the Illustrated Book.

The figure swayed up silently, and gradually compared to the dragon, Su Yu, who was insignificant, was suspended at the huge dragon head in front of him, and after seeing the exposed dragon scales that were not covered by the purple-black flames, he pressed it lightly with one palm.
