After all the poisonous miasma entered it, the heavy lid bell fell. Immediately after Su Ming urged the mana, the spiritual fire under the Ding Furnace instantly rose.

The condensation skills of the poisonous miasma are relatively demanding, because the poisonous miasma is originally thin, and if the firepower is large, it is easy to refine these poisonous miasma and directly refine it into nothingness. But if the firepower is not enough, it will not be able to refine the impurities in these poisonous miasma. So you need to be very careful.

Su Ming didn't refine the high-level Hundred Poison Cold Light Banner, in addition to the lack of materials, he was worried that he would waste this poisonous miasma. This time, a large amount of poisoning miasma was collected in Zhushan Sect, which was naturally used for practice.

With the passage of time, the flames in the Sanyang Divine Fire Ding slowly scorched this, refining the impurities in the poisonous miasma, and the poisonous miasma was also shrinking little by little, and the original black-gray poisonous miasma gradually turned into five colors.

The volume of that poisonous miasma was even smaller by dozens of times, and just when this poisonous miasma was about to be successfully condensed, the spiritual fire in the Sanyang Divine Fire Ding suddenly shook slightly, and the flames were a little bigger, only to hear a muffled sound in the Ding furnace, followed by a burst of smoke erupting, and there was a sweet and greasy mixed with a burnt smell in the air.

Su Ming made a trick, and the burning spiritual fire was instantly retracted, and then he waved his hand to open the lid of the tripod, only to see that inside the furnace, a cloud of charred black powder remained in the tripod. Just now, the spiritual fire it manipulated fluctuated a little more, and this poisonous miasma that was about to be successfully refined was refined.

Stretched out his hand to summon a ball of water and poured it into the Ding Furnace, casually shot out a spiritual light, and cleaned the Ding Furnace between breaths, Su Ming cleaned up his mood and lit the spiritual fire again, took out a gourd of poisonous miasma and poured it into it again.

After refining a furnace of poisonous miasma, Su Ming was not discouraged, and continued to refine. It's just that I don't know if I'm too unlucky today, and I continuously refined the poisonous miasma of the five gourds, but none of them succeeded.

After refining for a long time, most of the mana on his body was consumed, and Su Ming had to stop and recover his true qi.

"One is that the flame is unstable, once is that the refining time is too long, once the temperature is not up to standard and there are too many magazines, and the other two times are that the fire is not enough." Su Ming summarized the reasons for the failure of several refining.

After meditating and recovering his mana, Su Ming began to continue refining, and these refining failures were to put it bluntly, or his control of the spiritual fire did not meet the requirements. In the past, refining Xunfeng Hot Wheel Chong was not so high because the requirements for fire control were not so high, and Su Ming quickly mastered it. This time, the heat required for the condensation of the poisonous miasma was controlled very accurately, and this was the problem.

If you want to succeed in refining, in addition to gambling on luck, you can only exercise your ability to control fire. After understanding the problem, Su Ming began to conduct targeted training to control the stability of the spiritual fire.

Alchemy and alchemy have a lot in common, among which fire control is very important, in contrast, the fire control technique used in alchemy is more refined, after all, those medicinal materials are very expensive, and one is not careful to directly refine and waste.

How to practice the art of fire control? Except for a few who have specialized fire control techniques, they can only rely on the control of their divine consciousness to slowly explore and familiarize, to put it bluntly, they need to rely on long-term training to reach the point where practice makes perfect. Su Ming could only replace it with some cheap and large quantities of materials.

A large number of materials were piled up, and Su Ming's fire control technique had also been significantly improved, during which these practice materials were used up, Su Ming also spent money to acquire another batch in the hands of the Zhushan Sect disciples, and now he finally has some certainty.

Su Ming went to rest for a day first, adjusted his state, and then came to the retreat room again, and after taking out the Sanyang Divine Fire Ding, Su Ming waved his hand and shot out a spiritual light, and in an instant, a spiritual fire burned, and the Sanyang Divine Fire Ding began to warm up.

After the temperature reached the requirement, Su Ming took out a gourd of poisonous miasma and poured it into it, and then controlled the spiritual fire to start condensing. With the previous exercise, Su Ming's current fire control technique has been greatly improved, and the temperature of the spiritual fire has been controlled by him.

The poisonous miasma in the furnace was first wrapped in a spherical shape by the spiritual fire, and then slowly burned, refining the impurities in it little by little. As soon as the poisonous miasma came into contact with the spiritual fire, there was a sneering sound. The clumps of black gas continued to dissipate, and in just a quarter of an hour, the poisonous miasma in front of him shrank by half.

Then Su Ming continued to control the spiritual fire to burn, and after all the impurities in this poisonous miasma were refined, the original gray poisonous miasma became crystal clear, like a ball of crystal half, and the light could also refract five-colored light when it was illuminated, and this poisonous miasma was only the size of a walnut, like jelly, very beautiful.

After the condensation was successful, Su Ming began to continue to condense the remaining poisonous miasma, and the hundred poisonous cold light curtains required a hundred kinds of poisonous miasma, and Su Ming only had one. But after successfully condensing one, the rest is simple.

It took a day, and all the condensation of a hundred low-level poisonous barrier evil qi was finally completed, and then Su Ming began to refine the remaining materials, the refining of cold iron and cold attribute inner pill was not difficult, with the experience of condensing poisonous miasma, refining these materials could be said to be a piece of cake.

After an hour's effort, Su Ming finished refining all the materials, and then Su Ming began to put all kinds of materials into the Sanyang Divine Fire Ding for refining.

Su Ming was also a little nervous when refining the Hundred Poison Cold Light Banner for the first time, but after thinking that this was just a third-order magic weapon, he calmed down. The spiritual fire burned slowly, and soon all the materials began to slowly fuse according to a certain law, and the mana in Su Ming's body was also rapidly consumed.

At the same time, his divine consciousness began to manipulate these materials to slowly fuse, and constantly engraved one rune formation after another into them. Originally, many materials slowly fused together, and all the materials fused with each other at this moment, and the poisonous miasma and cold ice qi were also fused with each other, and a little bit of dark blue brilliance appeared in it, which was as beautiful as the stars in the night sky.

With the spiritual fire burning, this mass of material began to shrink slowly, and at the same time, those dark blue brilliance also became dim little by little, but this did not mean that it dissipated, but became restrained, and when all the brilliance was completely integrated, this mass of material had shrunk to the size of a chicken egg.

Seeing this scene, Su Ming also breathed a sigh of relief, but this was not the end, Su Ming began to engrave the remaining rune formations on it, and when all the rune formations were engraved, the cold attribute essence blood that had been prepared long ago was poured into it. The spiritual fire was flourishing, and it was refined into a ball of essence in the blink of an eye.

The Hundred Poison Cold Light Curtain quickly fused this essence energy, and after fusing the essence energy, the ice blue brilliance suddenly bloomed, and this Hundred Poison Cold Light Curtain was finally successfully refined.
