Coming out of the cave, the old man of Great Compassion stood quietly on the dirt slope, his heart of refining the golden pill of returning to the soul against the sky became more urgent, but there was still a day before the earth reached yin and yang.

In order to be foolproof, the old man of Great Compassion and Mu Tianyi checked the materials used in alchemy again, and during this time, Mu Tianyi also knew a lot of knowledge about alchemy.

Although Mu Tianyi knew that the materials used to refine the Heavenly Soul Returning Golden Pill were extremely precious and rare, when he saw it with his own eyes, he was still shocked in his heart, and his face was incredulous.

If you want to refine the Soul Returning Pill against the sky, in addition to the Buddha Crystal and the Eight Treasure Glazed Ding, the three most important materials are Linglong Root, Bodhi Flower and Phaseless Stone, these three treasures are hard to find.

In order to be able to gather the alchemy materials, the old man of Great Compassion spent countless time, experienced too many life and death crises, and spent too much effort, and every material in front of him contained the love of the old man of Great Compassion for his only daughter.

After waiting for a day and a night in torment, the old man of great compassion finally waited for the earth to reach yin and yang, and the old man of great compassion walked up the dirt slope with excitement and heaviness in his heart, his eyes full of determination.

Not far away, Mu Tianyi was quietly staring at the old man with great compassion on the dirt slope, his eyes were indeed full of worry and expectation.

At noon, the aura of heaven and earth in the valley suddenly became several times richer, and the old man of great compassion summoned the Eight Treasure Glazed Tripod out of his body, hovered in the air, and then instantly turned into a treasure tripod larger than a water tank.

As the old man of Great Compassion moved, a purple flame gushed out from the center of his eyebrows, gathering under the treasure and burning, and in the light purple flame, there was actually a bright starlight.

If you want to refine a superb Buddha Pill like the Heavenly Soul Returning Golden Pill, it is not possible to use ordinary flames, among the Seven Realms, only three flames, the Spiritual Flame, the Purple Star Separation Fire and the Yuan Shen Essence Fire, can be refined.

As the name suggests, the spiritual flame refers to the power of a person's spiritual mind, but all the elixirs refined with spiritual power are also the best divine pills or the best Buddha pills, but the current elemental cultivators are already rare.

As for the Purple Star Separation from Fire, it is the strongest flame in the Divine Realm, comparable to the Demon Flame of God Refining, which can incinerate the demon body of the Great Demon God in an instant, and is the flame used to refine the best Divine Pill and the Ultimate Buddha Pill.

Finally, there is the Yuan Shen Essence Fire, which is similar to the spiritual power, it is extremely dangerous to use, and the slightest carelessness will cause the gods to be destroyed, both of which are void and powerful magical flames, both of which are owned by elemental cultivators.

In order to find the purple star from the fire, the old man of Great Compassion traveled all over the south and the extreme north, the west and the ocean, and finally found the purple star from the fire in an ancient cave under the sea.

Next, the old man of Great Compassion put the alchemy materials into the Eight Treasure Glazed Tripod one by one, and for a while, the purple stars under the tripod burned more and more violently, and an amazing sense of oppression filled the surroundings.

Time passed little by little, and the alchemy materials in the Eight Treasures Glazed Tripod were ashamed to change, and finally all the materials turned into a mass of colorful liquid, seeing this, the old man of Great Compassion couldn't help but be happy.

Now that all the materials have begun to be fused, and the progress is going very smoothly, seeing the joy on the face of the old man of Great Compassion, Mu Tianyi, who has been watching the alchemy situation, also showed a relaxed expression on his face.

It didn't take long for the gorgeous liquid in the Eight Treasure Glazed Tripod to begin to condense, and the surrounding heaven and earth aura immediately converged, and the surrounding sense of oppression became more and more intense, and the old man of great compassion next to him suddenly felt a sense of powerlessness in his heart.

The thick aura of heaven and earth condensed into a cloud of light, covering the Eight Treasures Glazed Ding, the divine light flew around, and the outside of the Ding looked calm and unremarkable, but the inside of the Ding was indeed changing drastically.

The powerful coercion that erupted in the Eight Treasures Glazed Tripod greatly increased the pressure on the old man next to him, his face was solemn, and his eyes showed a look of pain, and his cultivation was completely worthless under the strong coercion.

Mu Tianyi, who had been watching from a short distance, also deeply felt the strong coercion, and seeing the painful old man, Mu Tianyi wanted to help, but in the end he held back.

The alchemy maker is different from the cultivation of the tribulation, when the tribulation is crossed, if you can't resist the thunder tribulation, others can help you, you can also succeed in the tribulation, but the alchemy maker really cannot, only the person who alchemy alone can succeed in alchemy.

Although the pressure is amazing, in order to be able to save his only daughter, the old man of Great Compassion gritted his teeth and held on, and his efforts paid off.

The originally gorgeous liquid condensed into a golden pill at this time, surrounded by essence, and there was a faint halo around it, looking at the golden pill suspended in the ding, the excitement in the heart of the old man of great compassion was indescribable.

At this time, the Soul Pill has been condensed and formed, almost refined, as long as the old man of Great Compassion can block the three Dan Tribulations, the Heaven Soul Returning Golden Pill can be refined by the Heavenly Thunder, and it can be regarded as a real refining.

With the clouds in the air, the thunder rolling, the entire valley was covered by the thunderstorm, and the powerful coercion filled the entire valley, so that the old man of great compassion was looking forward to but was afraid of the Dan Tribulation finally appeared in front of him.

At this moment, Mu Tianyi, who was not far away, suddenly felt inexplicably startled, and then turned sharply to look in the direction of the depths of the valley.

Soon, the current in the clouds of calamity rolled, the thunder condensed, and a cyan thunderbolt as thick as an arm condensed, rolling and flashing in the clouds, and the amazing power of destruction permeated all directions.

As long as he can block the three tribulation thunders, he can refine the golden pill of returning to the soul against the sky, and Bi Yuan can also wake up, these old men of great compassion know very well that for the sake of Bi Yuan, he must not lose.

I saw the old man of Great Compassion clasping his hands in front of his chest, silently reciting the incantation, his whole body flashed with a faint sea blue light, the vast and majestic qi burst out, and a golden-blue square seal slowly came out from the top of his head.

The square seal in front of him is the size of a bowl, golden blue, and the whole body is shining with divine light, and there is a majestic and vast atmosphere around it.

When he saw the square seal on the top of the head of the old man of Great Compassion, Mu Tianyi's heart couldn't help but be shocked, he didn't expect that the old man of Great Compassion was actually carrying the vessel of shaking the sea that had disappeared for thousands of years - the five-square seal.

Legend has it that there is a mysterious crack in the bottom of the sea in the depths of the boundless sea, which connects the evil spirits in the three realms of the outer world.

In order to ensure the safety of the real world, the ten powerful people of the ancient era took the essence of the five directions, the power of the stars, and spent a hundred years casting the five square seals, suppressing the cracks, and the people in the seven realms called it the vessel that shook the sea.

The old man of Great Compassion found the purple star from the fire in the ancient cave under the sea, and by chance, he found the Wufang Seal that had been missing for 10,000 years, although he finally took the Wufang Seal away, but due to the lack of cultivation of the state of mind, the Old Man of Great Compassion was never able to understand the Wufang Seal.

Since the old man of Great Compassion could not penetrate the Five Square Seals, the Five Square Seals could not be connected to his mind, and the Old Man of Great Compassion could not truly refine the Five Square Seals, and the true power of the Five Square Seals could not be fully released.

Although the cultivation of the old man of Great Compassion has reached the middle stage of Mahayana, and he can be regarded as a master of cultivation in the scattered cultivation of the cultivation realm, the magic weapon divine weapons that he can rely on are indeed pitiful.

If it weren't for the Wufang Seal, it would have been impossible for the Great Compassion Old Man to get the Linglong Root and Bodhi Flower, and the alchemy materials would not have been collected so quickly.

As soon as the five-party seal came out, the golden-blue light shield covered the old man with great sorrow, and in the next second, the cyan thunder that was split down slashed on the light mask with amazing destructive power.

The moment the cyan thunderbolt slammed into the golden blue light cover, the old man of Great Compassion was shocked, and blood slowly overflowed from the corner of his mouth, but he still swallowed the blood in his mouth stiffly.

With the sudden shock of the Wufang Seal, the golden blue light mask shook, and under the continuous impact of the cyan thunder, small cracks appeared on the light mask, and the powerful coercion made the old man of Great Compassion pale as paper, but he still gritted his teeth to support it.

Just when the golden blue light shield was about to shatter, the five party seals were full of divine light, and the vast and powerful divine power burst out, instantly shattering the cyan tribulation thunder, and the golden blue light mask finally disappeared.

Although the old man of Great Compassion blocked the first thunderstorm, but the true element in his body was consumed by more than half, and his mind was already confused, if it wasn't for the last moment of the Wufang Seal shot, I am afraid that the old man of Great Compassion would have been seriously injured by the thunder.

At this time, Mu Tianyi was more surprised than worried, he had felt the vast coercion of the Seventy-Nine Divine Tribulation when he was crossing the Tribulation in Chiyang, he didn't expect that the Tribulation that he had experienced in refining the best Buddha Pill could actually be comparable to the Seventy-Nine Divine Tribulation.

Now Mu Tianyi no longer cares about whether the Golden Pill can be refined, but begins to care about whether the old man of Great Compassion can survive under the Dan Tribulation, in his opinion, the cultivation level of the old man of Great Compassion is indeed not low, but his cultivation power is indeed not high.

As the rumbling thunder sounded, the clouds in the air instantly doubled, and the thunder in the clouds rolled, and the lightning flashed, and its powerful coercion was many times stronger than just now.

In the blink of an eye, a purple thunderbolt as thick as the mouth of a water tank was condensed in the clouds, and the rumbling thunder could be heard for hundreds of miles, and within a radius of a hundred miles of the valley, it was filled with a powerful pressure as vast as the sea.

Looking at the purple thunder and lightning looming in the clouds, Mu Tianyi swallowed his saliva violently, and looked at the old man with great compassion with worried eyes, and although the old man was surprised in his heart, he was really not afraid, because he had no way to retreat, and he couldn't retreat.

As the old man of Great Compassion injected the true yuan in his body into the Wufang Seal, the Wufang Seal, which was a little dim in brilliance, suddenly flourished, and kept expanding, and the Wufang Seal, which was originally the size of a bowl, actually became like a small mountain.

The thunder shook the sky, and the purple tribulation thunder slashed on the Wufang Seal with a devastating aura, and the powerful impact force swept across the four directions with the Wufang Seal as the center, countless spiritual energy evaporated instantly, and the valley became a mess.

The strong coercion generated by the purple thunder striking the Wufang Seal instantly crushed the surrounding boulders into powder, and the cliff walls were full of cracks, and the old man of Great Compassion was even more half-kneeling on the ground, and a mouthful of blood sprayed on the ground.

In the face of the strong impact, Mu Tianyi hurriedly dodged and appeared in mid-air as a streamer, looking at the valley like ruins, Mu Tianyi's worry in his heart became even stronger.

In addition to a five-sided stamped starlight gravel, the power of the vast and powerful stars burst out, instantly dispersing the purple tribulation thunder, and at this point, the old man of great compassion finally survived the second tribulation.

At this time, the five-sided seal in mid-air, the divine light flashed, and the momentum of the incomparably strong and arrogant was not reduced at all, and there was a hidden starlight shining gravel, but the heart of the old man of great compassion did not have a trace of joy, but was full of worry.

Although he did not refine the Five Directions Seal, the Great Compassion Old Man could still sense that under the powerful appearance of the Five Directions Seal, most of the energy was consumed, and it was unknown whether he could block the third thunder tribulation.

With the power of the Five Directions Seal, it can completely block the Dan Tribulation, and even devour the Tribulation Thunder, but the impatient Old Man of Great Compassion has not yet understood its mysteries, and the powerful power contained in the Five Directions Seal cannot be released.

Soon, the calamity clouds expanded again, and an even more powerful red tribulation thunder condensed in the calamity clouds, and a breath of destruction filled the four directions, and the powerful coercion made Mu Tianyi have to use the Dragon Emperor Ding to resist.

At this time of life and death, the old man of Great Compassion injected all the true yuan in his body into the Wufang Seal, and a mouthful of essence blood sprayed on the Wufang Seal, and after devouring the essence blood of the old man of Great Compassion, the Wufang Seal was full of stars and power.

In the blink of an eye, the red thunder struck on the Wufang seal, the entire valley was shaken, and the powerful destructive power swept around, and the old man of great compassion was forced into the soil, his face was full of freshness, and he didn't know whether he was alive or dead.

Suddenly, a pillar of stars shot out from the Wufang Seal, penetrating out of the tribulation clouds, rushing straight into the sky, the red tribulation thunder dissipated instantly, and the hundred-mile tribulation clouds slowly shrank.

At this time, the old man of Great Compassion, who did not know whether he was alive or dead, staggered up from the soil, his face was pale like a ghost, and his body was covered with blood and dirt, but when he saw the shrunken clouds of shame, an excited smile appeared on his pale face.

In order to fight against the red thunderstorm, the Wufang Seal exhausted all the power of the stars, the aura was weak, and the brilliance was dim and faint, like an ordinary stone, and then the Wufang Seal disappeared into the body of the old man of Great Compassion.

But just when the old man of Great Compassion and Mu Tianyi were happy to refine the golden pill, the shrinking clouds suddenly stopped, and the rumbling thunder sounded again, and the red, blue, and purple thunder rolled and condensed in the clouds.

It turned out that the clouds were not shrinking and disappearing just now, but condensing for the strongest three thunders in one.

Under the gaze of the Great Compassion Old Man and Mu Tianyi, the three thunderbolts finally fused into one and turned into a three-color tribulation thunder, whether it was power or strength, it was a hundred times more powerful than before the three tribulation thunders were fused.

Now the old man of Great Compassion has no Wufang Seal, and the true yuan in his body is also exhausted, and he is seriously injured, and he can't fight against the three-color thunder at all, but the old man of Great Compassion who is only one step away is really unwilling to give up.

Mu Tianyi understood the old man's unwillingness, but he couldn't watch the old man of great compassion hit the stone with an egg, and with the power of the Dragon Emperor Ding, Mu Tianyi appeared next to the old man of great compassion.

"Senior, get out of here!" Mu Tianyi anxiously urged.

"No, if the old man gives up, what will the blue duck do, even if he dies, the old man will not give up!" said the old man with great compassion as if he were dead.

"The power of this three-colored thunder is amazing, if the seniors insist on going their own way, not only will they not be able to refine the golden pill, but even the seniors will be wiped out!" Mu Tianyi shouted anxiously.

"Even if the body and spirit are destroyed, the old man will not hesitate to do it!" said the old man without wavering.

"Senior, have you ever thought about what Bi Yuan will do if you are gone?" Mu Tianyi shouted impatiently.

Listening to Mu Tianyi's words, the old man of Great Compassion was suddenly stunned, his eyes were full of entanglement and unbearability.

At this moment, the three-color thunder slashed down, Mu Tian moved with a thought, and the Dragon Emperor Ding appeared in the air, and the three-color thunder that was split down was swallowed.

Although the three-color thunder was devoured, and the clouds in the air quickly dissipated, due to the violation of the forbidden Heavenly Dao, in the end, the Great Compassion Old Man failed to refine the Heavenly Soul Returning Golden Pill.

Almost at the same time, the golden pill in the Eight Treasure Glazed Tripod suddenly shattered, turning into a trace of aura and disappearing into the air.

Seeing the Jin Dan shatter and then disappear, the old man of great compassion sat on the ground weakly, his eyes were dull, tears fell slowly, and Mu Tianyi next to him was also sad and self-blamed.
