In front of the alchemy furnace, Han Li's expression was solemn. His forehead was covered in sweat and his breathing seemed to be somewhat uneven.
He had already overestimated the difficulty of refining a Dao pill as much as possible, but now that he was refining it himself, he realized that he was ridiculously wrong.
The refining of a Dao pill was completely different from ordinary pills.
Although ordinary pills had ever-changing recipes, the process was basically to first refine all kinds of herbs, then gather these herbs, condense them into a pill shape, and finally leave the furnace.
Dao pills, however, were different. Everything about it was centered on the materials that contained the power of laws. Therefore, during the refining process, one had to refine the materials while continuously fusing the various materials and law materials in a snowball manner. This was equivalent to refining the materials and condensing the pill at the same time, which was more than ten times more difficult.
The fusion of various herbs, the control of the fire, the balance of medicinal properties, and other steps were even more complicated.
In particular, the main material crystal grain that contained the power of time also had to reach a certain balance with the various medicinal properties so that they could perfectly fuse, making the refining process even more difficult.
Han Li felt as if he was controlling an incomparably large army and practicing an incomparably complex military formation, but everyone in the army was not under his control, and there were even conflicts between them from time to time.
He had to balance all the conflicts while guiding everyone towards the direction of the military formation.
If it wasn't for his previous great improvement in alchemy, he would have been unable to hold on and failed on the verge of success.
However, even so, at this point in the refining process, he gradually felt that it was strenuous, but there were still many materials that had not been fused into the alchemy furnace.
After these materials were added, there would be more areas that needed to be controlled.
Because a Dao pill contained the power of laws, before the refining was completed, it could not come into contact with the power of other laws. Otherwise, it would cause a change in the semi-finished pill, and any accident would cause the refining to fail.
Therefore, Han Li's Mantra Treasure Wheel magical power could not be used at this moment, and he could only rely on his alchemy to support it.
He took a deep breath and raised his hand again, taking out a portion of materials and throwing them into the alchemy furnace. The furnace fire rose again.
As time passed, a few of the remaining materials were thrown into the pill.
Han Li's breathing became heavier, his cheeks flushed, and his eyes unconsciously became bloodshot.
After taking a deep breath, he emitted a blue light that wrapped around a material. It was a bottle of green spirit liquid, and he threw it into the alchemy furnace again.
The green liquid was refined in the alchemy furnace, and integrated into the white pill that had already turned into a ball.
A layer of green light appeared on the surface of the white pill, but it slowly dimmed and was about to completely disappear.
But right at this moment, the white pill suddenly trembled, and strange lights of different colors appeared on its surface, intertwining with each other and trembling violently.
Han Li's expression changed. He wanted to do something, but it was too late.
A muffled "pu" sound came from the white pill, and a crack appeared on its surface.
In the next moment, all the light on the surface of the pill disappeared, and the Spirit Qi that had filled the surroundings stopped abruptly.
All of this happened too suddenly, and everything returned to normal in the blink of an eye. It was as if he was not refining a Dao pill, but a normal pill.
Han Li heaved a faint sigh before casting an incantation seal through the air.
The silver flame at the bottom of the cauldron immediately dissipated and turned into a small silver flame man. All the flames were absorbed into his body.
With a wave of his hand, the cracked pill flew out of his hand, wrapped in a green light, and gently fell between his fingers.
Han Li brought the pill in his hand closer to his eyes, and the waves that had just appeared in his heart gradually calmed down.
He was already mentally prepared for his first failure in refining a Dao pill, especially since he was refining a Time Dao pill that contained one of the three Supreme Laws.
While thinking, his eyes lit up, and the corners of his mouth curved into a smile.
For other alchemists, this failed pill was just a waste, but for him, it was of great use.
Han Li formed a spell with both hands, and a golden light flashed behind him. The Mantra Treasure Wheel appeared, buzzing and rotating.
The 360 groups of time dao patterns on the treasure wheel all shone with dazzling golden light, and a golden vertical eye appeared in the center of the hole. It was the Eye of Truth.
The surface of the golden vertical eye flashed, and it slowly opened, revealing the eyeball inside.
Dazzling golden light radiated from the eyeball, and countless strange golden runes circulated on the eyeball, like countless stars flashing in the starry sky.
As these runes rotated, the golden light emitted by the Eye of Truth flickered endlessly, dazzling people, like a kaleidoscope.
After increasing the number of time dao patterns to 360 groups, the Eye of Truth's atmosphere and insight were completely different from before.
Han Li closed his eyes and used the Eye of Truth to perceive the surrounding world, and his eyebrows suddenly rose.
The layers of restrictions around the cave mansion were useless in front of the Eye of Truth, and it was easily seen through. Not only that, all the spiritual power flow on the restrictions was clearly displayed, as if he was looking at the patterns on the back of his hand.
Unfortunately, there were only a few restrictions around him, and he couldn't display the true observation ability of the Eye of Truth.
Han Li withdrew his gaze from the surroundings. The insight of the Eye of Truth would always be displayed in the future, but at this moment, he didn't care about it.
The golden pupil turned and looked at the waste pill in his hand.
The golden light on the Eye of Truth suddenly rose, and it shot out a seemingly substantial golden light, hit the waste pill, and integrated into it.
The waste pill immediately appeared with a dazzling golden light, and it kept tumbling, emitting waves of the power of time.
In the next moment, the waste pill suddenly rotated in the air, and the surface flashed with green light, and a green spiritual liquid separated from it.
At the same time, the waste pill flashed with various colors, and there were some small changes happening in various parts of the pill.
These were the changes after the green liquid and the various materials of the pill fused. Although it was a reverse change, the whole process could still be clearly seen.
Speaking of which, the reason why Han Li had the confidence to try to refine the pill was naturally because of the Eye of Truth's ability to reverse time.
A layer of blue light appeared in his eyes, and he stared at the waste pill, not letting go of any details.
Suddenly, his eyes moved slightly.
It was at this step that a mistake had caused the pill to explode.
The green liquid quickly separated from the waste pill, and the various colors of the pill dimmed, returning to the state before the green liquid was added.
Han Li's eyes flashed with blue light, and his heart was filled with joy.
After looking at it in reverse, as expected, he found the reason for his failure.
The changes on the waste pill continued, and a layer of white light appeared again, and then some white powder separated from it.
The pill once again appeared with various colors of light, and at the same time, there were some subtle changes.
Han Li did not make a mistake at this step, but now that he looked at it again, and combined it with his previous experience, he naturally had a deeper understanding of this step.
In this way, the waste pill separated from the materials from time to time, and the process of refining the pill was displayed in reverse.
Han Li looked at it from beginning to end, and he had a clearer understanding of the refining process of the Dao pill.
In the end, the waste pill was restored to the time crystal grain, and the process of condensing the time crystal grain was replayed again, and then it was completely over.
However, he did not care about this part.
The golden light flashed twice, then dissipated, and the waste pill appeared again.
Although he was now in the late stage of the Perfected Immortal Stage, using the Eye of Truth once still consumed more than half of his celestial spiritual power.
Han Li let out a long breath, took out a pill, and consumed it. He closed his eyes to refine the medicinal power, and at the same time, he carefully reviewed the refining process of the Dao pill in his mind.
An hour later, he opened his eyes, and a divine light flashed in his eyes. His spirits were greatly lifted.
He did not immediately start refining, because the time crystal grain needed a month to condense.
In the following month, Han Li didn't do anything else. He merely used his Eye of Truth to observe the pill refinement process over and over again.
In the blink of an eye, a month passed.
The Sky Bottle finally condensed another drop of green liquid, and Han Li immediately condensed it into a time crystal grain.
Then, he took out another set of materials, and began the second round of refining.
After watching the refining process countless times, Han Li was very familiar with the refining process, and very smoothly completed the previous steps, and soon reached the step of fusing the green spirit liquid.
He took out a bottle of green spirit liquid, and with a single hand, poured the spirit liquid into the pill furnace.
In the scorching hot pill furnace, the green liquid was refined, and shrunk by more than half.
Han Li waved his hand, and a green light enveloped the green liquid, and fused it into the pill.
His two hands quickly formed a seal, and the green liquid gradually fused into the pill. The pill flashed with a green light, and then dissipated steadily, without any problems.
Seeing this, Han Li heaved a sigh of relief, took out the next material, and threw it into the pill furnace.
Perhaps it was because he had seen the refining process so many times before, the refining process was very smooth, and he successfully fused the materials into the pill.
In the blink of an eye, there were only six or seven materials left.
But at this moment, Han Li's expression became serious, and a layer of sweat appeared on his forehead, as if he had reached a certain limit in all aspects.
He gritted his teeth, and with a wave of his hand, took out a white spiritual glue, and added it into the pill furnace.
Suddenly, a white light flashed in the pill furnace, and there was another muffled sound, followed by a charred smell.
Han Li's brows furrowed, but they soon relaxed.
He closed his eyes and rested for a moment, recovering his tired mind. Then, he waved his hand, took out the waste pill, and at the same time, formed a seal.
Buzz!
The Wheel of Truth appeared again, and he quickly used the Eye of Truth to look at the waste pill.
A golden light flew out, and submerged into the waste pill. Suddenly, a large golden light appeared on the waste pill, and began to reverse the refining process.
With the Eye of Truth, Han Li quickly found the reason for this failure …
A month later, he repeated the same method, and began the third refining.
During this period, he was like before, constantly using the Eye of Truth to observe the refining process.
The Eye of Truth's Time Reversal ability was almost equivalent to letting him refine so many times, and accumulated rich experience.
Just like before, Han Li smoothly completed all the previous steps, and then took out a white spiritual glue, and threw it into the pill furnace.
He had already understood the key to this step, and his hands formed a seal, and quickly completed it.
Han Li took out the next material, and threw it into the pill furnace.
At this moment, the refining of the pill was nearing its end. He only needed to fuse the remaining seven materials into the pill, and it would be considered a success.
He had only failed twice, and he had achieved this result, so he was quite happy.
But after a quarter of an hour, he could not be happy anymore.
