Huo Xuan stood on a small sand dune, looking at a flat desert in front of him, the terrain here is extremely ordinary, without any characteristics that can attract people's attention, similar to this flat sandy land, in the vast desert, there are almost countless, this inconspicuous place, but there is a strange fire atmosphere.

"Brother, is there really a fire here?" Looking at the sandy land that seemed to be the same, Qing Liang was a little puzzled.

"Well, there are no special buildings or strange caves here, but since there are no on the ground, there are no in the sky... Well, this is the place for the fire! Huo Xuan grabbed a handful of sand in his palm, then slowly sprinkled it down, and chuckled.

"Brother means underground? So how do we go down? It's impossible to dig indiscriminately, right? Hearing this, Qing Liang was slightly stunned, and then asked with a puzzled face.

"Hehe, it's naturally impossible to dig through, since there can be a strange fire in this underground, there is naturally a passage formed by it."

Huo Xuan shook his head with a smile at the green scales, and then took a deep breath, the Guiyuan Soul Recipe began to operate, Huo Xuan's hands quickly formed a mysterious seal knot, and with the formation of Huo Xuan's hand seal, an extremely low roar faintly came from his body!

Suddenly, the soul power entrenched in the center of the eyebrows instantly diffused out, and after setting off a circle of invisible ripples in the mid-air in front of Huo Xuan, it plunged into the sand, and the vast soul perception began to spread in all directions.

This is a kind of induction of different fires, using a large area of soul power to perceive and detect, ordinary Douhuang powerhouses can't squander their soul power like this, unless they arrive at Douzong, after the soul power is transformed, there will be no load, but for Huo Xuan, who has specialized in cultivating soul power exercises since he was a child, he can withstand such consumption.

"I've finally found it."

After half a sound, Huo Xuan breathed a sigh of relief, and his eyes focused on a depression not far away that was filled with a burst of fiery and furious energy.

There are a lot of fighting skills in the Huo Xuan Society, but they are all above the ground level, if it is used to open the way, this low-level Purple Spirit Sword Technique is a good choice.

At this time, Huo Xuan's hands began to form a simple knot again.

"Buzz!"

With the formation of Huoxuan's handprint, a strong purple light appeared in an instant, and the energy of heaven and earth surged wildly, and the land within a radius of thousands of feet suddenly surged.

The surging heaven and earth energy continuously condensed a purple long sword in mid-air, and the ripples suddenly fluctuated on the surface of the sword body.

"Boom!"

The purple sword was almost like thunder, and with a momentum like a bamboo, it instantly slammed into the depression.

Suddenly, the earth shook, and countless sands burst open, scattering like a flood of countless grains of sand, revealing a huge hole after half a sound.

Huo Xuan's eyes glanced at the inside of the hole, it was pitch black, and a slight faint heat rose out of it, only to see the surrounding sand and soil continue to flow in, and there seemed to be signs of full ground, so it can be seen that this hole is bottomless.

……

In the dark passage, Huo Xuan hugged the green scales in his arms tightly, and the soft strange feeling made Huo Xuan enjoy it very much.

The bodies of the two of them continued to slide down with the help of the slope of the passage, and in the small hands of Qing Scale, they were holding a moonstone, a faint soft light, emanating from it, allowing Huo Xuan to distinguish whether there was an obstruction in the road ahead.

After falling to the ground, Huo Xuan reluctantly let go of the green scales in his arms, pulled her forward a few steps, and swept his eyes on the road ahead, and sure enough, there were more than a dozen black passages like in the original book.

After Huo Xuan sensed it carefully, he took the green scales and took the lead in walking towards a passage on the left, which was obviously extremely long, and it was a deep pitch black as far as the eye could see.

In the passage, there seems to be no concept of time.

As the distance deepened, Huo Xuan suddenly noticed that the cold feeling that enveloped his body suddenly dissipated, and was replaced by a faint heat.

"Qing Scale, if you notice that you can't hold on, then tell me, you know?" Lowering his head, Huo Xuan said softly to the green scales.

"Hmm." Qing Liang nodded obediently, and the look on his little face didn't seem to be anything unusual because of the blazing fire attribute energy around him.

As the two of them deepened, the surrounding fire attribute aura became more and more intense.

"It's coming." Turning a corner again, a red glow appeared at the end of the passage not far away. The speed of the two of them also increased, and they quickly passed through the short distance, and then came to the end of the passage.

In the huge crypt, the fiery red magma flowed slowly in it, and occasionally a huge bubble emerged from the magma, but after a while, with a slight sound, "bang", it burst open, and the blazing magma burst out of it, like a fiery red firework.

Huo Xuan lowered his head, looking at the green scales that had been following him closely, and couldn't help but be a little stunned, in her body, it seemed that a steady stream of cold energy was being released, and it was the support of these energies that enabled the green scales to follow him all the way to the end of the passage, this blue snake three-flower pupil was really a bit strange!

"Brother, there seems to be something hidden in that magma!" The green eyes looked at the endless fiery red magma, and said with some doubts.

"Green Scales, what do you feel?" A smile gradually appeared on Huo Xuan's face, and he turned his head sideways to ask Qing Scale, who was full of doubts.

"There seems to be something in that magma, and I can feel a little bit of its faint aura, but it's not as strong as my brother."

The green scales stared at the churning magma somewhere, and a little ghostly light appeared in the turquoise eyes, as if they had penetrated the barrier of the magma and saw the mysterious thing hidden beneath it.
