(Thank you for your friend's leisurely love and the wolf's support along the way, thank you!)

Waiting for Long Tian to confirm that there was no problem with the medicinal materials and fire crystals, Qin Yuntian waved his hand gently, and a fiery red Dan furnace more than half a meter high appeared next to the stone platform, the outer wall of the Dan furnace was engraved with ancient runes, thick and simple, and he flicked his fingers lightly on the Dan furnace, making a clear humming sound, and it was a good Dan furnace, it seemed that Qin Yuntian had really put a lot of thought into it. Pen, fun, and www.biquge.info

"Good thing, really good thing!"

Long Tian admired, and then said to Qin Yuntian: "Brother, please protect the Dharma for me outside, and don't let anyone come in to disturb me before Dancheng." ”

Qin Yuntian was slightly stunned, he didn't expect that Long Tian wouldn't even let him watch from the side. But he also knew that most people didn't like to have people around when they were refining pills, so he didn't think much about it, nodded and went out, closed the door of the cultivation room, and personally protected the Dharma in front of the door.

Long Tian also has no way, when alchemy, Xiaoyaozi must come out to control his body, although he can trust Qin Yuntian as a person, but Xiaoyaozi's existence is still as unknown as possible. This is also the reason why Xiaoyaozi still did not show up in the face of the threat of thunderbolts that day, there are many strong people in the inner courtyard, and some must be careful.

After checking that everything was fine, Long Tian closed his eyes slightly and began to exchange control of his body with Xiaoyaozi. He was already familiar with this kind of thing, and in just a short moment, an extremely powerful aura had risen on Long Tian's body, but it was Xiaoyaozi who had already controlled the control of Long Tian's body.

Long Tian opened his eyes, his eyes quickly swept over the medicinal herbs, fire crystals and Dan furnaces in front of him, his fingers moved slightly, a fire crystal had already appeared in his hand, and the next moment, a small but extremely hot flame appeared in his hand.

The palm of the hand sank slightly, and the cluster of flames was put into the Dan furnace from the fire mouth, and when it entered the Dan furnace through the fire port, the small flame suddenly expanded and burned fiercely, and just when the surging flame was about to overflow the Dan furnace, a faint red gas film quietly sealed the fire mouth and stopped the flames.

Looking at the vigorous flames burning at the bottom of the Dan furnace, Long Tian nodded with a smile, obviously very satisfied with the degree of combustion caused by this fire crystal.

Then, Long Tian took a lily with a jade-like stamen from the stone platform beside him, opened the lid of the Dan furnace, and threw it in.

Under the high temperature of the churning flame in the Dan furnace, the jade heart lily, which was originally as crystal as jade, quickly dissolved like butter on fire, but after a while, it completely melted into a puddle of white liquid.

As if he was extremely satisfied with this process, a faint smile appeared on Long Tian's face, his fingers twisted slightly, and the elf-like flames in the Dan furnace immediately increased the fire, and the temperature in the Dan furnace rose rapidly, and the palm-sized clean ** body quickly evaporated at high temperatures, shrinking and decreasing at a speed visible to the naked eye......

This process is very boring to remove impurities from the medicinal herbs at high temperatures, until the liquid after the dissolution of the jade heart lily has shrunk several times, leaving only a puddle of liquid the size of a thumb. But at this point, the liquid had become very viscous, forming a gelatinous substance.

Next, Long Tian began to process the other medicinal herbs in turn, the steps were still the same, the process was still so boring, when he put the Fuye Grass, White Bone Vine, Qingxin Orchid, and Yin Driving Branch...... After the impurities were removed one by one, the time had already reached noon, and half a day had passed.

Long Tian obviously had no intention of stopping for lunch, and after a little rest, he began to further refine the medicinal liquid, but this time, he did not refine the medicinal materials separately in batches, but poured all the medicinal liquids that had removed the impurities into a gelatinous form, and poured them all into the Dan furnace for unified refining and purification.

More than a dozen gelatinous medicinal liquids are clearly divided in the Dan furnace, and they are being refined at the same time. Perhaps it was because the consumption of Divine Consciousness by Unified Refining was too huge, and Long Tian's originally relaxed expression gradually disappeared, replaced by dense beads of sweat on his forehead.

But at the same time, the more than ten kinds of viscous liquid medicine are also gradually solidifying, gradually condensing into small crystals, under the high temperature caused by the scorching flame, they have no resistance at all, and they are allowed to be refined at will at high temperature.

However, Long Tian's refining was obviously not over yet, his fingers twisted, adjusting the size of the flame and the level of temperature, and continued to refine the medicinal liquid that had already formed crystals.

"Whew!"

Another full hour passed, and Long Tian, who was already covered with beads of sweat, finally let out a long breath, and the more than a dozen medicinal liquids in the Dan furnace had all turned into fine solid-colored powders, and finally, the crucial step of drug purification was finally completed.

After taking out the jade bottle that had been prepared long ago and carefully packing more than a dozen kinds of powder one by one, Long Tian had time to wipe his sweat, and a satisfied smile appeared on his face.

The next step should be Ning Dan, and Long Tian had to be cautious about this. He didn't rush for a while, but first took a pill and meditated on the spot to breathe, he had to adjust his mental, physical, and yuan forces to the best state in order to complete this last step.

It didn't take long for Long Tian to finish pranayama, speaking of which, this is really a loss of the effect of the fire crystal, if according to Xiaoyaozi's previous practice, the previous process of removing impurities and refining and purifying will inevitably consume a large amount of Yuan power, and it is impossible to fully recover in this short period of time.

Getting up and coming to the Dan furnace, Long Tian took out a few more fire crystals, stimulated them with Yuan Force and threw them into the Dan furnace, and the flames in the Dan furnace instantly rose again. Long Tian waited quietly, his fingers twisted to adjust the fire, and when he felt that the fire had arrived, he immediately picked up a bottle of medicinal powder that had been purified just now and poured it into the Dan furnace.

Long Tian's right hand kept twisting his fingers, and at the same time, with his divine sense, he controlled the flames rising in the Dan furnace, but his left hand did not stop, and poured the previously purified medicinal powder into the Dan furnace in turn according to a certain order.

Although Long Tian's movements were fast, the medicinal powder was still changing rapidly under the high temperature in the Dan furnace, and in a few moments, it was estimated that it would be scorched and discolored.

Pouring the last medicinal powder into the Dan furnace, Long Tian wiped it on the storage ring, and a slightly larger jade bottle appeared in his hand, casually pulled out the cork, and poured all the reddish liquid in it onto the medicinal powder in the Dan furnace.

This pale red liquid is a pill prepared in advance by Xiaoyaozi, and it is made with a few flavors of elixir and fire spirit spring water, in order to improve the rate and efficacy of the elixir. (To be continued.) )
