Han Li's expression darkened. He waved his hand to stop the flames beneath the furnace and retrieved the failed pill with a single hand.

The improvement in pill refining this time was minimal. He only managed to integrate one material into the pill before failing again when trying to integrate the second.

The closer he got to the end of the pill refining process, the more difficult it became.

Thinking of this, Wang Yu couldn't help but frown.

With the Eyes of Truth, no matter how difficult the pill refining process was, as long as he examined it repeatedly, he was confident he could overcome it.

It was just that he only had nine sets of pill refining materials prepared, and now he had already used three. If he still couldn't refine a Dao pill with the remaining six sets of materials...

He took a deep breath and didn't think about it any further. He used the Eyes of Truth again, looking at the failed pill...

A month later, Han Li began his fourth attempt at refining.

The initial steps were completed smoothly, and soon he reached the point where he had failed before.

With the previous repeated observations and the help of the Mantra Treasure Wheel, he quickly overcame this step and successfully integrated a piece of light golden honey into the pill.

He calmed his mind and looked to the side. There were still five kinds of materials left.

Han Li gritted his teeth secretly, picked up the next material, and threw it into the pill furnace.

His expression was extremely focused, and a faint cyan light appeared on his face. He quickly made hand seals, using his pill refining skills to the extreme.

Inside the pill furnace, the pill rolled slightly, the surface shimmering with various colored lights, fluctuating dimly.

Each time a new material was added, it was necessary to adjust the relationship between the new material and the other materials in the pill to achieve a new balance. This was like pouring a basin of cold water into a pot of hot oil, without allowing any oil to splash out.

Han Li made hand seals as fast as wheels, trying his best to control the conflicting medicinal powers within the pill, so that it would stabilize.

"Bang!" a soft sound!

Han Li's hand seal movements suddenly froze, and his expression turned gloomy.

This time, he failed without even successfully integrating a single material.

He sat in silence for a long time, took out the failed pill, and used the Eyes of Truth to look at the failed pill again.

A month later, the fifth pill refining began.

After a month of repeated examination, Han Li already understood the reason for the previous failure. This time, the pill refining result was the same as before, successfully overcoming this difficult point.

However, when fusing the next material, even though he was extremely careful and used his pill refining skills to the extreme, it still ended in failure.

Han Li smiled wryly, using the Eyes of Truth to check this failed pill, searching for the reason for the failure.

Then, after waiting for a month, he began refining again, and only then did he successfully pass.

In the blink of an eye, two or three months passed.

Han Li sat cross-legged in the cave, his ten fingers blooming like lotus flowers, forming one hand seal after another.

From time to time, faint crackling sounds came from inside the pill furnace, and various colored lights flickered, although separated by the furnace lid, some still leaked out from time to time.

Moreover, the air was filled with a rich medicinal fragrance.

Next to him, there was no material, all the materials were integrated into the pill in the furnace.

In the past few months, for the remaining materials, although Han Li had tried his best every time he refined, he had not succeeded in one attempt. All of them were successful only after summarizing experience with the Eyes of Truth.

Although he gradually overcame the difficulties step by step in this way, the materials he prepared were also exhausted. Now, the one in the furnace is the last one.

As for fusing the last material, he had already failed once before, and had repeatedly observed it several times with the Eyes of Truth, and had secretly pondered it no less than a hundred times in his heart. If there were no accidents, this refining should be no problem.

Now what he has to worry about is the subsequent pill tribulation.

He only has this one material now. If he can't resist the pill tribulation, he won't have a second chance for at least the next few hundred years.

The Dew凝草, the Heaven 天造参, and other things are easier to handle. He still has some seeds and seedlings in his hand, and he can continue to ripen them with the Green Liquid.

However, some other non-spiritual grass materials cannot be ripened with the Green Liquid. He has to spend Immortal Essence Stones to buy them. Among them, some materials cannot be easily bought outside, especially several main spiritual materials. He found them in Tao Yu's storage magic tool. If he had to find them himself, he didn't know how much time and energy it would take.

Now that he is in the Black Wind Sea Area, naturally he doesn't need to say more. Even if he offers a reward to buy them in the Impermanence Alliance, he can't buy them at all.

So this is the last chance, and he must not lose it.

Han Li mustered all his energy, his divine sense probing all the changes in the pill furnace, his hands forming hand seals, manipulating everything in the pill furnace.

At this moment, various medicinal powers in the pill furnace are in fierce conflict, like a pot of boiling water, with thousands of threads and ends.

Even though he has mastered the key to this pill refining, he still feels extremely strenuous.

Time passed little by little, and Han Li's mind slowly entered a state of unparalleled calm, like a pool of waveless ancient well.

His hand seals became slower, but every move exuded a strange charm.

One after another, the hand seals flew out of his hands like flowing water, sinking into the pill furnace.

The original extremely complex situation in the pill furnace became simple in Han Li's eyes, and the manipulation became more and more easy.

The various medicinal powers that were in fierce conflict in the pill furnace suddenly slowed down, and quickly moved forward according to the steps recorded in the pill formula.

A smile appeared on his face. His pill refining skills unknowingly took a big step forward, breaking through the bottleneck and entering a new realm.

Han Li took a light breath, his expression became solemn again, and the hand seal in his hand suddenly changed.

Boom boom boom…

The sound in the pill furnace became louder and louder, like thunder roaring, but it was not the pill bursting, but the agitation of various vitality.

The various colored lights emitted from it became more and more dazzling, and gradually merged into one, turning into pure gold.

Han Li's eyes lit up.

He knew that the scene before him was a sign that the pill was about to be completed.

The hand seal in his hand was even more urgent, the golden light in the pill furnace became more and more brilliant, and from time to time condensed into various shapes such as dragons and tigers, and colorful clouds, the medicinal fragrance emitted was more and more rich, like orchid and musk.

Roar roar roar!

At this moment, the sound from the pill furnace suddenly changed, as if a giant beast was roaring.

With a loud "bang!"

An incomparably dazzling golden light suddenly burst out from the pill furnace, the furnace lid was blown off, and a ball of incomparably dazzling golden light flew out of the furnace, which was a golden pill the size of a dragon's eye.

One after another, flame-like golden rays of light bloomed from the pill, condensing into circles of golden light waves, rippling towards the surroundings.

Golden Dao patterns representing Dao pills appeared on the surface of the pill, exuding a mysterious and unparalleled fluctuation of the law of time, almost like the way of heaven.

Moreover, the golden Dao patterns on the pill were actually two.

Han Li's eyes flashed with a hint of surprise when he saw this scene.

He didn't expect the Dao pill he refined to reach the second grade. It may be that the power of time in the time crystal grain is very strong, or it may be other reasons.

In any case, a second-grade Dao pill is much more effective than a first-grade Dao pill.

At this moment, the originally clear sky above the island suddenly became turbulent, and countless golden light spots appeared, quickly forming a huge golden cloud, rolling endlessly.

Looking from a distance, the golden cloud could not be seen at a glance, as if it filled the entire sky, and the sea below was also reflected in gold.

An immensely vast fluctuation of the law emanated from the golden cloud, and the vitality of the world within a radius of tens of thousands of miles rolled violently.

The fluctuation of the law in the golden cloud was too strong, and the monks millions of miles away also felt a burst of inexplicable palpitation, and looked towards the location of the golden cloud.

The golden cloud rolled violently, and the color suddenly became more and more intense. In a few breaths, it seemed to turn into substance, covering the entire sky, and not a ray of sunlight could penetrate.

Although the entire sea area was illuminated into a bright golden color, it gave people an extremely heavy feeling, as if the entire world was squeezing over.

Inside the cave, Han Li felt the situation outside, and frowned.

Although he had seen the records of pill tribulation in the classics, he did not expect the power to be greater than he thought.

Rumble!

There was a rumbling sound in the golden cloud, the wind was surging, and a huge golden vortex suddenly appeared, spinning quickly.

Dazzling golden light emerged from the center of the vortex, making a sizzling sound.

A terrifying fluctuation of the law that seemed to crush everything suddenly descended from the vortex, covering the cave.

Crackle!

Cracks appeared on the walls in various parts of the cave, and Han Li's body also shook.

A golden thunder light flashed above the cave, and the figure of Crab Daoren emerged.

He looked up at the golden cloud in mid-air, and faint golden lights flashed in his pupils. Some emotional fluctuations appeared on his wooden face.

At this moment, the golden vortex in mid-air suddenly lit up, and a dazzling golden light shot out from the vortex, hitting the cave below.

The golden light contained countless golden runes, flashing frantically, exuding a terrifying wave of the law of time.

However, this wave of time power obviously carried a strong sense of killing.

Crab Daoren did not try to stop it, but just stood quietly in place.

At this moment, a golden light flashed and hit the cave, directly sinking into it.

The restrictions outside the cave, and the stone walls were not damaged in the slightest. The golden light seemed to be illusory, directly penetrating in.

Inside the cave, Han Li sensed the situation outside, and was shocked.

The speed at which the pill tribulation descended was far beyond his expectation.

He quickly urged the magic formula in his heart, and golden light radiated from his whole body. The Mantra Treasure Wheel emerged, and countless dense golden ripples emerged from the treasure wheel, wrapping the golden Dao pill.

At the same time, he opened his mouth and sprayed out, and seven star rings flew out. The star rings spun around like lightning, nested and connected together to form a larger ring.

It was the Seven Luminaries Star Ring.

Dazzling starlight radiated out, forming a star curtain, with countless star patterns blinking on it, like a miniature version of the starry sky.

Thumb-sized starlight runes jumped on the light curtain, exuding traces of law fluctuations.

Before he could react further, the top of the cave flashed, and a golden light had already shot down extremely quickly, hitting the star curtain.

The star curtain immediately lit up, and all the star runes on it shone brightly, making bursts of sharp whistles, trying to resist the golden light.

However, the golden beam of light flickered, and as if it had pierced the roof of the cave, it directly passed through the star curtain and accurately hit the Dao pill.
