At noon, the sun was shining, the birds in the valley were singing and the flowers were fragrant, the air was fresh, and there was no intention of leaving the customs after a day and a night of retreat.

As soon as he entered the ancient cave, Mu Tianyi found that the cave was filled with a cold atmosphere, and on a cold stone, there was a young and beautiful girl in pink who was pale as a ghost and lifeless.

Under questioning, Mu Tianyi learned that the girl in pink was named Bi Yuan, who was about the same age as herself, and was injured by a red-bone golden scorpion a few years ago, and her whole body was covered with scorpion venom, which devoured her mind, and her three souls and seven spirits were extremely weak.

The red bone golden scorpion is a long-extinct divine beast of the wilderness, the whole body is golden, it has devoured the golden liquid of the gods in the primeval era, and achieved the strong body of King Kong immortal, and its cultivation has exploded, and its tail thorns are indestructible, extremely poisonous, and even the emperor of the gods is a little jealous.

Inadvertently, the old man of Great Compassion discovered the incomparably cold and magical ancient cave in front of him, and the cold qi in the cave froze the scorpion venom in Bi Yuan's body, saving her life, but it did make her enter a state of deep sleep.

"Senior, as far as I know, the Red Bone Golden Scorpion has long been extinct, how could your daughter be injured by the Red Bone Golden Scorpion?"

"In the depths of this valley, there is an unusually old cave, the playful blue duck, because of chasing a hare and broke into the cave, who would have thought that the red bone golden scorpion was actually in the cave!" said the old man with remorse and self-blame.

"And what happened later?" Mu Tianyi asked anxiously.

"The Red Bone Golden Scorpion just stabbed the Blue Duck, and did not stop the old man, seeing that the old man rescued the Blue Mandarin, the Red Bone Golden Scorpion also retreated to the depths of the cave!"

"This is also too strange, the Red Bone Golden Scorpion will not let go easily to anyone who violates it, how can it be possible to watch the seniors leave!" Mu Tianyi said even more puzzled.

"Actually, the old man also felt very strange, there were nine blue stripes on the tail thorn of the red-bone golden scorpion, and its cultivation time must have been ten thousand years, if you want to kill the old man and the blue duck, it is as easy as a finger!" said the old man in confusion.

"Maybe it's the red-boned golden scorpion that has a lot of kindness!" Mu Tianyi could only joke impatiently.

Suddenly, a bone-chilling cold air gushed out from under the cold stone, and the surrounding stone walls were suddenly covered with frost.

But in a moment, the entire cave seemed to be completely frozen, and there was frost and cold air everywhere, and Mu Tianyi, who couldn't stand the cold anymore, and the old man of Great Compassion, hurriedly transported the true yuan to resist, but to no avail.

Impatiently, Mu Tian moved with a thought, and a tripod-shaped light mask covered him and the old man of great sorrow, and the old man of great compassion who was covered with frost suddenly let out a long breath and sat down in the light mask.

As the source of chaos and the power of the Nine Shades of Darkness swam around his body, Mu Tianyi's bone-chilling chill disappeared in an instant, and a warm feeling made Mu Tianyi feel indescribably comfortable.

"Senior, what kind of cave is this, why is it so cold?" Mu Tianyi still looked around with some fear.

"Actually, the old man didn't know very well, at that time, he saw that the cold air here could freeze the scorpion venom, so the old man put the blue duck here, but he really didn't know anything about this cave!"

"Such an amazing cold, I'm afraid even that ice demon can't reach the dust!" Mu Tianyi said to himself.

"What did you say?" asked the old man of Great Compassion.

"It's nothing, senior, the cold in this cave is so amazing, it shouldn't be an ordinary cave!" Mu Tianyi guessed.

After looking around, Mu Tianyi's gaze fell on the cold stone, to be precise, it should be under the cold stone.

When Mu Tianyi and the old man of Great Compassion walked within three meters of the cold stone, a trace of cold air poured in through the light mask, and the two who had a shadow of the cold air hurriedly retreated to a place three meters away.

As more and more cold air gushed out, the cold stone and the blue duck on it were pushed into the air by the amazing momentum, and an ancient spring was exposed.

The seemingly ordinary ancient spring was cold, and the entire cave instantly turned into ice and snow, and it was extremely cold, and what was even more terrifying was that the thick cold air actually completely sealed the entrance of the cave.

Mu Tianyi and the old man of Great Compassion, who have died, have no other choice now, unless they can find another exit, they will have to sleep in the ice cave with Bi Yuan.

Impatiently, Mu Tian's mind moved, the Dragon Emperor Ding appeared in the sky, the brilliance flashed, and with a dragon groan, a dragon shadow roared and rushed towards the ice wall, and the ice wall was shattered in an instant.

But Mu Tianyi and the old man of Great Compassion were not happy for long, and the entrance of the cave that was shaken was instantly frozen again, and Mu Tianyi, who did not believe in evil, tried more than ten times in succession, and soon after the hole was shaken open, it was instantly frozen again.

After more than a dozen attempts, Mu Tianyi not only failed to escape, but spent a lot of vitality, and in the end, Mu Tianyi put away the Dragon Emperor Ding and gave up unwillingly.

Just when Mu Tianyi was competing with the entrance of the cave, the old man of Great Compassion was indeed looking at the ancient spring gushing cold, and for the ancient spring in front of him, the old man of Great Compassion always had a familiar feeling, as if he had seen it somewhere.

"It seems that if we want to get out, I'm afraid it won't be too easy!" said the old man with a solemn face.

"What do you mean, what do you mean that it won't be too easy?" Mu Tianyi looked at the old man with great compassion in confusion and surprise.

"If the old man remembers correctly, this ancient spring is the legendary Frozen Sky Ice Spring, and the old man has obtained an ancient book that records the situation of the Frozen Sky Ice Spring!" said the old man with a worried face.

"Frozen Sky Ice Spring, why have I never heard of it, what is Frozen Sky Ice Spring, and how can we get out of here?" Mu Tianyi asked with an anxious face.

"According to ancient records, there is an ancient spring on the bank of the Tianhe River in the fairy world, there is no spring water in the spring, only an extremely cold air, and every thousand years, the cold air in the spring will erupt and freeze the Tianhe!" explained the old man of Great Compassion.

"Immortal Realm Tianhe, in this way, this Frozen Sky Ice Spring is from the Immortal Realm?" Mu Tianyi looked at the Great Compassion Old Man in surprise.

"The ancient books do not say where the Frozen Sky Ice Spring came from, only that since the Frozen Sky Ice Spring appeared on the banks of the Heavenly River, no one in the fairy world dared to set foot in the Heavenly River, and after the destruction of the Immortal Realm, the Frozen Sky Ice Spring was nowhere to be found!"

"Even the Tianhe River can be frozen, and the immortals dare not approach, this Frozen Sky Ice Spring is too domineering, senior, what else is said in the ancient books?" Mu Tianyi asked with great interest.

"Let the old man think about it...... By the way, the ancient books say that there is a Frozen Sky Divine Sword hidden in the Frozen Sky Ice Spring, which is the coldest weapon condensed by the cold qi of the Ice Spring over thousands of years, which can seal the sky and freeze the earth, and the power is infinite!" There was a hint of uncertainty in the tone of the old man of Great Compassion.

"Frozen Sky Divine Sword, it sounds quite domineering, but I don't want to freeze into a popsicle, forget it, senior, did the ancient book say how to get rid of the cold of the Frozen Sky Ice Spring?" Mu Tianyi retreated.

"No!" said the old man without thinking about it.

"Senior, don't answer so quickly, think again, think again!" Mu Tianyi said without giving up.

"The old man knows what you mean, but there is really no other record in the ancient books!" said the old man with great compassion a little wronged.

The affirmation of the old man of great compassion made the hope that Mu Tianyi had finally ignited in his heart disappear in an instant.

At this time, the cold air in the frozen ice spring burst out, and the icy cold made the cave even colder, and even Mu Tianyi and the old man of Great Compassion in the light mask felt a chill to the bone.

Without the slightest hesitation, Mu Tianyi hurriedly urged the Dragon Emperor Ding to strengthen the light shield to resist the cold air, but no matter how Mu Tianyi added the light mask, he still couldn't stop the cold air from pouring into the light mask.

As more and more cold air poured into the light mask, Mu Tianyi and the old man of Great Compassion shivered again, their beards and hair were instantly covered with frost, their bodies stiffened with shame, and their consciousness became weaker and weaker.

When life and death were at stake, Mu Tianyi unreservedly ran the source of chaos and the power of the Nine Shades of Darkness in his body, his stiff body was much better, the chill to the bones disappeared, and a warmth surged into his heart.

But when Mu Tian, who was warm all over, turned his face to see that the old man with great compassion next to him was already stiff and cold all over, but the old man was still supported by a true element in his body.

With Mu Tianyi's help, the old man finally regained consciousness, his whole body was warm, and he felt an indescribable sense of comfort in his heart.

Although the two escaped death, in the face of the surging cold, the two knew that they would not be able to support it for long, so they had to find a way to get out of the cave quickly, otherwise they would really freeze to death here.

Suddenly, the sword light flashed in the frozen sky ice spring, the cold air became more and more cold, and the extremely cold sword qi burst out from the spring well, scattering in all directions, every time the sword qi hit the light mask, Mu Tianyi couldn't help but feel a shock in his heart.

At this moment, countless sword qi and the surrounding cold qi all poured towards the Frozen Sky Ice Spring, a sword light flashed, and the Frozen Sky Divine Sword filled with icy cold air hung above the ice spring, and the white beads on the sword head flashed with a bone-chilling cold light.

Suddenly, the long sword sent out a powerful impact force that swept all around, and the ice on the stone wall shattered instantly, revealing the uneven stone face inside, and even the frozen hole was shattered.

"Frozen Dzi, it's really Frozen Dzi, I didn't expect that the old man would be able to see Frozen Dzi with his own eyes!" The old man of Great Compassion looked at the white beads at the head of the Frozen Sky Divine Sword with an excited face.

"What kind of frozen dzi, senior, why are you so excited, isn't it just a broken bead, let's leave this place of right and wrong quickly!" Mu Tian urged with a frightened face.

"Don't you know, the Frozen Sky Bead is the condensation and transformation of the true source of the Frozen Sky Ice Spring, and even the Divine Yuan of the Great Heavenly God can be easily frozen, and the world only hears its name!" the Great Compassion Old Man explained excitedly.

But just as Mu Tianyi and the old man of Great Compassion were about to leave, something suddenly happened that shocked the two of them.

Suddenly, the Frozen Sky Sword appeared on Bi Yuan's body, the cold air was pervasive, the sword qi surrounded, and a white light suddenly shot out from the Frozen Sky Bead, piercing out of Bi Yuan's eyebrows, and the white light carried a drop of Bi Yuan's essence blood.

When the white light disappeared again in the Frozen Sky Bead, Bi Yuan's essence blood flowed down from the Frozen Sky Bead, and flowed down the snow-white blade, and was about to drip to the ground, and the essence blood was instantly swallowed by the Frozen Sky Divine Sword.

Mu Tianyi and the old man of Great Compassion, who are also cultivators, can be said to be very familiar with the scene in front of them, but the two of them did not expect that the Frozen Sky Divine Sword would actually recognize Bi Yuan as the master, and set a blood contract, and they will not give up on life and death.

After recognizing the master, the Frozen Sky Sword turned into a cold light and disappeared into the body of the blue duck, and the blue duck and the cold stone slowly fell.

At this time, the blue duck's whole body exuded a cold but soft cold air, and the frozen scorpion venom in his body was compressed into his palms, and his pale face also showed a little ruddy.

Seeing Bi Yuan's ruddy face, the old man showed an excited and relieved smile on his face, and his eyes were even more moist unconsciously.

"This Frozen Sky Divine Sword can actually compress the scorpion venom scattered throughout the body in the palm of your hand without the help of external force, it is really extraordinary!" Mu Tianyi said excitedly.

"Now Bi Yuan's mind and soul have improved, but as long as the poison of the Red Bone Golden Scorpion remains in the body for a day, it will kill Bi Yuan at any time, and the Frozen Sky Divine Sword can only suppress the scorpion venom, but cannot completely get rid of it!" said the old man of Great Compassion worriedly.

"Seniors don't need to worry, as long as we refine the Heavenly Soul Returning Golden Pill, we can get rid of all the scorpion venom!" Mu Tianyi said confidently.

"You're right!" said the old man agreed.

Glancing at the still unconscious Bi Yuan, the old man of great compassion resolutely turned around and left the cave, and Mu Tianyi followed out.
