The temperature of the flame attached to the surface of the earthly liquid is extremely high, and cultivators in the slightly weaker Turbidity Pill realm may be injured, so they need to wrap it with their own true yuan in order to refine it safely.

Moreover, if you want to make the most effective use of the Diyan liquid, the best way is to swallow it and refine it in the body, which is even more dangerous, even the cultivators of the Jade Pill Realm need to be extremely careful when refining.

After all, the meridians and acupoints in the human body are extremely fragile, and the overspeeding operation of one's own true element alone will leave dark wounds, not to mention that it is almost directly subjected to the scorching liquid of the earth.

Therefore, every cultivator in the realm of the Three Dans needs to be extremely focused when swallowing the refining earth Yan liquid, as long as the slightest distraction will cause irreparable consequences.

Just like what Yi Chen saw in front of his eyes, just by seeing it with the naked eye, he could clearly see that the true yuan used to wrap the earth's Yan liquid was constantly making a "sizzling" sound under the scorching fire, and accompanied by bursts of dark gray white smoke, which was decreasing at a speed visible to the naked eye.

Because of this, when refining the Diyan liquid, it is necessary for the cultivator to continuously provide the true element, so that he can use the characteristics of the Diyan liquid to practice while ensuring his own safety.

However, at this moment, the effect of the earthly liquid is also showing a few points, under the scorching fire, although the true element of the dust is constantly dissipating, but the color change of the remaining part of the true element is also extremely obvious.

The true element of Yichen is a black-gray that is almost black, and there are many black parts, but at this time, the color of the true element has become much lighter, from the original black-gray that is almost black to dark gray, and it has also become more refined.

The appearance of this change also means that the quality of the true element in Yi Chen's body has been improved a lot, and under the influence of such a true element, the impurities in his body will also be further removed.

With the entrance of the Diyan liquid, Yi Chen felt a burst of dry lips, and his lips cracked due to the lack of moisture, but this degree was still within the tolerance range of Yi Chen.

Fortunately, there was a steady stream of true yuan wrapped in the earthly Yan liquid, isolating the terrifying temperature emitted by the Yan fire, so that it did not bring more pain to Yi Chen.

However, as Yi Chen slowly swallowed the Diyan liquid, his body gradually began to tremble, and the expression on his face became more and more uncomfortable, and his ruddy face appeared pale.

The earthly liquid wrapped in the black-gray true yuan was like a small iron ball placed in the furnace, tossing and boiling in his throat, burning the inside of his body little by little, making him feel the slightest pain.

However, as he ran the Diyan liquid to the meridians, this pain soon began to lessen a lot, and under his inner vision, he saw a scene that surprised him.

As soon as the Diyan liquid appeared in Yi Chen's meridians, the gray meridians gradually softened under the scorching heat, and a large number of impurities attached to it turned into wisps of gas, which were discharged from the body with Yi Chen's breathing.

"Sure enough, it is worthy of the Diyan liquid brought by the meteorite, just a drop has such an effect", seeing such an obvious effect, Yi Chen's heart was not only amazed, but an inexplicable sense of comfort poured into his mind, making his whole body a lot easier.

That feeling is like the pleasure and comfort brought by being suddenly cured after a long illness, and the whole person's feeling is completely different from before, which makes him immersed in it for a long time and difficult to extricate himself.

But he was quickly awakened by the presence in his body, quickly got rid of this state, and began to devote himself to the next step of refining.

The Diyan liquid slowly followed the meridians to the dantian, and the Yan fire attached to the surface had been nearly extinguished in the entanglement and confrontation with the True Yuan in Yi Chen's body, and now only a few traces were still burning under the attack of the True Yuan.

The red liquid inside was also exposed, carefully wrapped by the dusty True Yuan, exuding a faint warm breath, quietly suspended directly above the True Qi Yuan Dan.

The next step will be the most important step, and it is also the most anticipated step for Yi Chen, that is, to completely pour this drop of Diyan liquid on the True Qi Yuan Dan, and then use the cooperation of the residual Yan Fire to start removing a large number of impurities mixed in the True Qi Yuan Dan while refining the Diyan liquid, as long as this step is successful, then you can see the results that Yi Chen wants to see.

However, this step is not a simple operation that can be completed, you must know that once a cultivator condenses the True Qi Yuan Pill, it means that they have almost all the life qi in their body integrated into it.

In other words, from the moment the True Qi Yuan Pill appeared in the cultivator's body, it was something that was tied to the cultivator's life, and once it suffered a fatal blow, it would have an unimaginable impact on the cultivator.

Although Yi Chen didn't have the slightest doubt about the effect of the Diyan liquid in his heart, now that it was his first attempt to refine it, he didn't know what his next step would be.

However, his cultivation had reached this point, and Yi Chen had already seen the powerful effect of the Diyan liquid on his own meridians and acupoints, if he changed his actions just because of this little unknown factor, wouldn't it be a waste of this drop of Diyan liquid.

"I can't care so much, as long as I can temporarily alleviate the problems in my body, at least before the plan starts, I can rest assured that I can improve my cultivation, and I can have a greater grasp when the time comes", Yi Chen was firm in his heart.

However, just to be on the safe side, he took out two bottles containing a green liquid and a red elixir from his storage bag and put them within his reach, and then dispersed the True Yuan that controlled the Diyan liquid wrapped in his body.

In Yi Chen's inner vision, this drop of Diyan liquid did not make the slightest mistake, it completely fell on the True Qi Yuan Dan, and the moment the two came into contact, the flame that was about to be extinguished disappeared in his extremely shocked inner vision.

"Hmm..."

Just when Yi Chen was feeling strange about this, a strong shock suddenly appeared from inside the True Qi Yuan Dan, and a sharp pain appeared in his mind, making him can't help but snort.

"Click... Click..."

Just when he felt strange, three small cracking sounds appeared in his mind, and when he shifted his mind to the dantian, he noticed that three extremely small cracks began to spread outward from the inside of the True Qi Yuan Dan, looking like they were going to divide the True Qi Yuan Dan into three parts.

However, as the three cracks appeared on the True Qi Yuan Dan, Yi Chen, who had just come back to his senses, was in a trance, and his body seemed to be in a raging fire, and he instantly felt the pain of burning and blazing in his body.

"Ahh

Such a sudden change was really beyond Yi Chen's expectations, and there was a deep sense of regret in the eyes that had been opened, and a low panic sound couldn't help but come out of his mouth.

As soon as Yi Chen's low cry fell, three small flames appeared from the three cracks on the True Qi Yuan Dan that had cracked separately, and began to swim on the surface of the True Qi Yuan Dan like a small snake.

An even more intense cone-like pain suddenly appeared in Yi Chen's mind, suppressing all the feelings in his body, leaving only this kind of pain that was almost extreme in his feelings.

"Ahh Woo... Gurgling"

Under the stimulation of such severe pain, Yi Chen didn't hesitate too much, his right hand, which was constantly trembling because of the pain, drank the green liquid he had taken out earlier with difficulty, and then endured the severe pain, and also wrapped it with true qi, slowly spreading sixty percent of it to the meridians and points in the body, while the rest were all transported to the dantian and sprinkled on the true qi yuan pill like clear water.

After doing this step, the pain that Yi Chen felt was also reduced a lot, but before the cold clear liquid completely took effect, he could still only endure this unimaginable severe pain.

Half an hour later, Yi Chen's face began to gradually improve, although it was still pale without a trace of blood, but his tired eyes were full of surprise.

Looking at the empty bottle with some feeling, Yi Chen secretly felt lucky in his heart, if it weren't for the existence of cold clear liquid this time, I'm afraid he would have to endure it for a longer period of time to get rid of that pain.

However, he quickly focused all his attention on his dantian, and as soon as he moved, wisps of True Yuan appeared from the True Qi Yuan Dan and began to walk around the True Qi Yuan Dan.

At this time, the True Qi Yuan Dan didn't look much different from before, and the True Yuan in it didn't change too significantly.

But in Yi Chen's inner vision, he could clearly perceive that the volume of the True Qi Yuan Pill at this time had decreased slightly, but it had become more compact, and the impurities in the True Yuan were also much less.

However, under Yi Chen's subsequent estimation, he found something that made him feel helpless, that is, the true yuan in his body still needed nearly thirty drops of Diyan liquid to completely turn from black gray to dark gray.

However, what made him feel a little relieved was that he still had nearly fifteen drops in his hand, which could still provide a lot of help for his next practice.
