As soon as the two of them entered the Xuanyin Cave Cellar, a cold air suddenly hit, as if they had entered an ice cellar, and there was almost no light in the cave, but from time to time there was a yin wind attacking, like a knife cutting. This is only not far from the entrance, and it is already like this, which shows the abundance of cold.

Xuchen and Songhe Daochang each turned on the flashlights they had prepared and followed the terrain of the cave.

The terrain of the cave was tortuous, and the two of them walked about 500 meters, and the terrain suddenly went downward, and the cold was even worse. Fortunately, the void dust is okay, the cultivation has reached the late stage of condensation, and the physique has not invaded by cold and heat, and the Songhe Dao Chief is almost a little bit, and hurriedly transports the true yuan to resist.

After going down for about two hundred meters, the cave became narrower and narrower, less than two meters high and no more than five feet wide. The two of them carefully walked another fifty meters or so, and the terrain suddenly rose again.

When the two of them climbed about 100 meters, they could vaguely see the light, and then the terrain began to flatten again, and the cave gradually widened. After continuing to walk for dozens of meters, a natural karst cave suddenly opened up in front of him, the size of a football field, dozens of meters high, and the thick stone pillars stood like stalagmites.

I saw that the cave was shining, and there were many purple and blue crystals growing on the stalagmites, which illuminated the cave in various colors. The stone walls and stalagmites of this natural cave cellar are condensed with a layer of ice crystals, and the whole cave is like a crystal palace.

Along the way, the void dust released his divine sense, but he didn't find the shadow of Zhixian. At the moment, I looked more closely, and found that there was an exit at the end of the cave, from which the light was refracted.

These crystal rough stones are not of much value except for their good looks, and Xuchen and Songhe Dao Masters are both cultivators, so they don't care too much about these things, so they ignore them directly.

Seeing that nothing had been found here, Xuchen walked towards the end of the cave, and Songhe Dao Chang followed closely.

As soon as he got out of the cave, Xuchen saw a sight that shocked him.

I saw that this is a natural cave on the belly of the mountain, small at the top and large at the bottom, like a huge pyramid. The ground is 300 meters in circumference and several hundred meters high, and the stone walls are covered with white crystal rough stones, all of which are condensed with ice crystals several inches thick. In the center of the mountain, there is a natural cold pool with a radius of 100 meters, the water of the pool is turquoise, and the slightest cold air floats on the water, as if shrouded in a layer of white light veil.

There is a blue lotus flower growing in the cold pool, emitting a glow and radiance, and the radius of ten meters is as bright as day. The size of a lotus basketball, the petals resemble a burning flame, carved like ice crystals, and shine with magnificent light.

Next to the blue lotus, another black lotus flower moves with the wind, but this black lotus is the size of a basin, black gas, the veins on the lotus are blood-red, flashing with a trace of red light, it looks extraordinarily charming.

"Xuan Ice Fire Lotus, Black Flame Holy Lotus!"

Xuchen was so excited that he almost cried out, these are all rare elixirs! After the Xuanbing Fire Lotus matures, it bears a total of eighteen lotus seeds, each of which is made of Xuanbing Cold Flame, which can be refined into the body and cultivated into a great magical power "Xuanbing Cold Flame", which is extremely powerful, and can even freeze the planet when cultivated to perfection.

It can also be refined into a top-grade elixir to improve cultivation, but to refine the top-grade elixir, at least at the level of an alchemy master.

And the lotus seeds of the Black Flame Holy Lotus can cultivate the Black Flame Holy Flame, and the cultivation to perfection is enough to burn the mountains and boil the sea.

During this time, he memorized all the "Genius Earth Treasure Illustrated Guide", so as soon as he saw the appearance of the two elixirs, he recognized them.

"Daoist Songhe, this blue lotus is already an immortal medicine, and it already has a medicinal spirit, so it may be the body of the Zhixian you see. This black lotus doesn't seem to have cultivated the medicine spirit yet, I'll take a look first. Xuchen looked at the already stunned Songhe Daoist and said with a smile.

"This is an immortal elixir? There are actually two of them!Is what Master Wei said true?" Daoist Songhe was so excited that he almost trembled.

"Of course it's true. Xuchen nodded, used his wind control technique, and flew towards the pool.

He came to the black lotus and gently touched the lotus with his hand, the black lotus suddenly shrank, and instantly shrank into the water and disappeared without a trace.

Almost at the same time, there was a "bang", a black wind swirled on the surface of the water, and in the splash, a huge black shadow rushed out of the water at a speed that covered its ears and was not in a hurry, and threw the dust into the air with a "snap".

Xuchen seemed to have been hit by a giant hammer, and his chest turned over and over, and he suffered a small loss, and he couldn't help but be taken aback! The person in the air suddenly lifted his true qi, fell lightly to the surface of the water, snapped a few times in the water, returned to the shore, and then turned his head to look.

In the cold pool, a huge black demon snake rose from the water, revealing its twenty-meter-long upper body. The head is as big as a water tank, the eyes are like lanterns, the red light is shining, and the snake crown on the top of the head is like a black lotus flower swaying from side to side. The thick body is black and shiny, and there is a circle of golden markings around each scale, as if it is inlaid with gold threads, which is very beautiful!

Only then did Xu Chen know that the Black Flame Holy Lotus turned out to be transformed by the snake crown on the head of the demon snake, and this demon snake was the famous desolate beast Xuanbing Black Snake, and he was born to be good at using the snake crown to transform into a black lotus to confuse other creatures.

After the Xuanbing Black Snake became an adult, it was at least a thousand meters long, and it was extremely terrifying. This one looks like it's still a juvenile, and judging by the aura it emanates, it's already a second-level demon beast, and its strength is comparable to that of a Terran monk in the late stage of Tongxuan.

The strength of the demon beast continued to improve with its advancement, from level one to level nine, which was equivalent to the strength of the human race cultivator from the Qi Refining Realm to the Yuan Infant Realm. As for the tenth-level demon beast, it can already be reborn and transform into a human form.

"Second-level demon snake. "Xuchen's face changed wildly, this is not something he can fight against at all, unless he uses the best spirit sword.

When Songhe Dao Chang saw it, he was so frightened that his thighs were weak and he trembled!

The demon snake's body twisted, opened its huge mouth, stretched out a snake letter several feet long, let out a "hiss" sound, and suddenly spat out a mouthful of red flames tens of meters long at them.

The two of them quickly retreated, the flames were still ten meters away from them, and they only felt as if they were in a furnace, and their mouths were dry, which showed the horror of the flames.

Without waiting for their extra time to think about it, the Xuanbing Black Snake had already quickly chased after them.

"I can't think about it anymore, or I'm going to capsize in the gutter today. Xuchen's mind was racing, and he made a decision in an instant. A little jade plate on his chest activated the defensive vajra cover, and then the white light flashed in his hand, and he took out the best spirit sword.

Only then did he say to Songhe: "You hide aside, I'll fight it." ”

Daoist Songhe nodded hurriedly, turned around and ran.

At this moment, the Xuanbing Black Snake had already ascended the cold pool, revealing its body more than fifty meters long. With a sudden twist, an afterimage was drawn towards the void dust like thunder.

"Boom!"

More than a dozen stalagmites as thick as a water tank were torn apart like tofu under the touch of the demon snake, flying everywhere.

Xuchen used the stunt of "Swallow Three Directions to the Water and Flying to the Clouds", flew directly to a height of 100 meters, and grabbed a protruding stone to dodge this blow. Then run the True Yuan and activate the Spirit Sword.

Xuchen felt that the mana in his body was surging towards the spirit sword like flowing water, and in a breath, almost half of the mana in his body was gone, and the spirit sword suddenly shone brightly, and the whole body was red, radiant and radiant, exuding a divine glow.

At this time, the demon snake suddenly jumped dozens of meters high, opened its mouth and bit towards the void dust.

"Go!" Xuchen took a little spirit sword, and the spirit sword was as fast as a streamer, and it circled around the seven inches of the demon snake, and then flew back in a circle.

Blood spurted out of the head of the demon snake immediately, and the entire huge snake head immediately fell.

Rumble!

Like an earthquake, the head and body of the snake fell to the ground, struggling desperately, smashing the ground with a thumping sound, and the sound of Weng Weng echoed in the belly of the mountain. After about half a minute, the snake's head remained motionless.

"This is dead?" Xuchen flew down, a little jade plate, and removed the vajra cover. Holding the spirit sword in his hand, he walked over to inspect it.

I saw that the incision of the snake's head was smooth like a mirror, and the blood flowed all over the ground, and there was no breath at all, and it was completely dead.

Xuchen breathed a sigh of relief, and found that there was a layer of fine sweat on his head, and it was the first time he had seen a huge demon snake, and his mood was inevitably nervous.

Daoist Songhe walked over slowly, revealing a shocked and inexplicable complicated expression.

"Master Wei, you will kill it with one sword.....? This is the legendary flying sword?"

He looked at the brilliant spirit sword in Xuchen's hand and almost groaned and asked.
