In the quiet and tranquil purple bamboo forest, Long Xiaotian and You Yi stood side by side, standing in front of the Purple Eagle Ding that was rising from the flames.

"The temperature is enough, I'll guide you on the sidelines, let's get started. You Yi saw that the pale yellow flames in the Purple Eagle Ding were already burning, and tilted his head to Long Xiaotian and said.

Long Xiaotian nodded, grabbed a small grass that was as black as ink, and threw it directly into the Purple Eagle Ding.

This is a black underworld grass, with a low grade, and it is generally used more when refining low-level mortal weapons.

The Black Stygian Grass entered the Purple Eagle Ding, and was immediately swept up by the pale yellow flames, completely engulfing it.

"Poof!"

In the blink of an eye, the Black Stygian Grass was turned into ashes in the raging flames and burned to ashes.

Long Xiaotian looked at the black underworld grass that had been burned to ashes in a moment, his expression was quite embarrassed, it was obvious that he had failed as soon as he got started, which made him feel a trace of frustration rise in his heart.

"Go on. You Yi saw it in his eyes, his face was calm and waveless, he just opened his mouth lightly, and he didn't say anything.

Long Xiaotian took a deep breath and slowly calmed down the waves in his heart. After several days of practicing the theory of alchemy, he also understood that when he first started refining, it was very normal to fail, and every great master of refining, when they first started refining, it was not smooth, they all learned from failure, constantly improved, perfected, and finally achieved themselves.

After a few breaths, he slowly opened his eyes, calm as a secluded pool, without the slightest ripple.

He grabbed a black undergrass again and threw it into the Purple Eagle Ding, and the pale yellow flames rose up, drowning the black underworld grass and burning continuously. Under the high temperature, the originally moist and bright Black Stygian Grass also withered as quickly as shrinking, slowly turning into ashes in the flames, and drops of essence were refined.

"Poof!"

Long Xiaotian was overjoyed in his heart, and the power of the Yuan Shen that controlled the temperature suddenly relaxed slightly, and the flames swept up, and the entire Black Stygian Grass instantly turned into nothing, and the essence that was finally extracted was also burned clean.

"Don't be distracted, do not be distracted, so that you can perfectly control everything in the refining tripod. You Yi said in a deep voice, with a hint of sternness in his voice.

Although Long Xiaotian was a little frustrated, he was not discouraged, and once again grabbed a black underworld grass and threw it into the refining instrument ding, burning it.

"Poof!"

"Poof!"

"Poof!"

“......”

The black underworld grass thrown into the Purple Eagle Ding was constantly burned by the raging flames and turned into flying ashes, but Long Xiaotian's control of the temperature of the flame became more and more perfect.

Finally, after burning more than two dozen black underworld grasses in a row, Long Xiaotian finally mastered the trick. His heart was as quiet as a secluded pool, and his gods were like white jade, and he adjusted the temperature of the flame through the information fed back by the power of the primordial gods, and after more than ten minutes of difficult calcination, he finally completely refined the essence of the black underworld grass.

He immediately took out the jade bottle and filled it with the refined essence.

"Huhuhu...... It's not easy to finally successfully extract the life essence from the Black Underworld Grass!"

Long Xiaotian was panting, sweating profusely, his face was pale, and he sat on the ground regardless of his image, looking at the jade bottle containing an impure liquid, he showed a happy smile.

In order to be able to refine the life essence in the Black Underworld Grass, he spent a lot of money, and because of the depletion of spiritual power, he had to stop temporarily, and only after recovering his spiritual power more than a dozen times in a row did he refine it, but it was not pure and contained certain impurities.

"It took an hour and failed more than 20 times, but the extracted essence ingredients were not pure, and they did not meet the standards of refining, which is not good. You can rest for a while, and when your physical strength is almost recovered, you can continue refining. ”

"Refine until I'm satisfied. ”

You Yi took the jade bottle in Long Xiaotian's hand, looked at the liquid containing impurities in the jade bottle, frowned slightly, and said dissatisfied.

Long Xiaotian could only express this with a wry smile, and he finally understood why You Yi had to wait until he was promoted to the Qi Acceptance Realm before letting him officially refine the weapon. Because this is too much spiritual power, and it is also a great loss of the power of the primordial gods.

If it weren't for the fact that the meridians in his body were relatively thick after remodeling, they could hold more spiritual power than ordinary people, and there was also the "Spiritual Channeling Song" that could summon the spiritual energy between heaven and earth for him to quickly recover his spiritual power, plus the Purple Eagle Ding was an intermediate-level spiritual weapon, and it was also able to actively absorb spiritual energy and turn it into raw materials for burning flames, with him as a person who opened the pulse realm, it was really impossible to refine the essence of the Black Underworld Grass.

Maybe You Yi really took these factors into account and let him refine the weapon in advance.

If you don't advance to the Qi Acceptance Realm, you can't open up a sea of Qi to accommodate more spiritual energy, you can't practice spiritual determination, accelerate the absorption of spiritual energy and the recovery of spiritual power, it is impossible to withstand such serious losses, and this is just refining the most ordinary material, and the materials behind it are even more difficult to refine, and the consumption is unimaginable.

Long Xiaotian was so eager to break through to the Qi Acceptance Realm at this moment, because the repeated recovery and consumption made him exhausted, affecting his refining level and state.

However, there is another benefit, that is, in the repeated consumption and recovery, Long Xiaotian's sixth vein is actually being cultivated at a snail-like speed, although the progress is extremely slow, but over time, it is also extremely terrifying.

After he rested for about fifteen minutes, the spiritual power lost in his body and his own physical strength were all restored.

After more than 20 failures, the experience summed up, although his refining speed and level at the moment are not as good as those of a great refining master like You Yi, but in the eyes of You Yi, it is still remarkable.

It took him an hour, and he refined a total of more than a dozen bottles of material essence. You Yi stepped forward to inspect one by one, among which ten bottles of material essence were not perfectly refined, leaving some impurities, and the other four or five bottles were considered to have reached his standard, and one bottle of material essence was refined to be crystal clear, shrewd and flawless, flowing with a faint luster, without the slightest impurity, flawless.

You Yi's pupils shrank slightly, and there was a faint hint of surprise in the depths of his pupils.

"This bottle of material essence is very well refined, I hope that every bottle of material essence you refine in the future can meet this standard, only when each material essence is perfect, the quality of the refined utensils will be impeccable." ”

"It's already noon, you have a good rest, and we'll continue refining the materials in the afternoon. ”

You Yi's figure flickered and disappeared suddenly.

Long Xiaotian poured out the ashes in the ding, then put them away, walked towards the waterhole, sat cross-legged on a flat rock, breathed and exhaled, swallowed the spiritual energy of heaven and earth, and replenished the consumed spiritual power.

The waterfall falls down like the Milky Way above the nine heavens, the sound is like thunder, roaring and roaring, huge and shocking, splashing up the wisps of water vapor, overflowing between the heaven and the earth, under the illumination of the bright sun, bursting out of the brilliant and dazzling brilliance.

The waterfall roars, the waterhole is clear, the bamboo forest is quiet, the birds are chirping, the scenery is beautiful, picturesque, everything is so quiet and tranquil, peaceful and natural, a harmonious and leisurely color ripples in the purple bamboo forest, permeated with an inexplicable rhyme, which makes people calm and escape into the empty wonderland.

While swallowing the aura of heaven and earth, Long Xiaotian recovered the lost spiritual power, recalled the picture of the refining weapon in his mind, pondered carefully, slowly reminisced, learned lessons and experiences from failure, and laid a solid foundation for success.

The waterhole is clear, the fish happily jump out of the water, splashing white waves, and the gentle breeze sweeps by, blowing the tips of the hair, giving people a wonderful artistic conception of warmth and comfort.

Long Xiaotian unconsciously immersed in the memory of the refining weapon, while reminiscing, while pondering and deducing, soon he had no distractions, as if he was the only one left in the heaven and earth, under the independent and vast sky, he experienced the vastness and majesty of the universe, and his mood was like water, soft and slight.

An inexplicable Dao rhyme appeared around Long Xiaotian, giving people an ethereal and hazy feeling, which was very unreal.

Long Xiaotian was deeply immersed in this kind of empty wonderland, and his spiritual sense spread infinitely, until the end of heaven and earth, he seemed to feel that his state of mind suddenly opened up, and he had the ethereal feeling of clearing the clouds and mist to see the blue sky.

This kind of extremely mysterious realm is very rare for cultivators, and some amazing and brilliant people may be able to enter this kind of empty and wonderful realm by chance, and get great benefits, but it is difficult to trigger it repeatedly.

Long Xiaotian was able to enter this mysterious empty realm, which can be regarded as a kind of creation and an opportunity for him
