The moon hangs high and the stars are dotted.

There was not a trace of clouds in the clear night sky, and the bright moonlight sprinkled down, and everything seemed to be covered with a layer of frost and snow, a piece of silver white.

Such a beautiful night, Liu Xiaoxu has no intention of appreciating it.

At this time, he was sitting quietly in the room, with an alchemy furnace in front of him, and several unknown medicinal materials were placed in the furnace. A dark blue flame burned silently beneath the furnace.

Liu Xiaoxu looked focused and stared at the medicinal materials in the furnace.

He is using the alchemy method taught to him by He Zhixing during the day, independent alchemy!

The elixir refined by Liu Xiaoxu is called the Awakening Pill, which has the effect of refreshing the mind. The reason why refining the Awakening Pill, rather than the Quenching Pill, is that the medicinal materials of the Awakening Pill are cheaper and more common, and it is the most suitable for practicing hands.

To refine the Awakening Pill, a total of three medicinal materials are required, which are Ice Heart Grass, Fire Dragon Incense, and Tranquility Flower.

As the temperature in the furnace gradually increased, it was not long before the three-flavor herbs began to show signs of melting.

Liu Xiaoxu perked up, pointed a little, and punched three spiritual qi into the furnace. These three spiritual qi shot towards the three flavored medicinal materials in the furnace, wrapping them one after another.

This step is crucial.

You must know that alchemy is actually the process of melting and fusing medicinal materials, and then cooling and solidifying. Without the aura wrapping, the herbs will naturally merge with each other after melting, which is difficult to control.

And wrapping the medicinal herbs with aura, the result is different. As long as the aura does not disperse, even if it is placed in the same furnace, the medicinal materials will be distinct from each other and will not be fused together, which can have a good isolation effect.

Why do you want to wrap the herbs with aura and control the fusion of the herbs?

First, there are impurities in the medicinal materials, and these impurities will affect the success rate of alchemy, as well as the grade of the elixir. The fewer impurities a pill has, the higher the grade of the pill. If the impurities in the medicinal materials are not peeled off in advance, and several medicinal materials are allowed to merge with each other, the impurities will directly affect the medicinal properties of the pill, and the success rate of alchemy will be greatly reduced.

The only way to do this is to wrap several herbs separately with aura, then peel off the impurities in each herb separately, and finally fuse them together.

Second, the medicinal materials are all divided into primary and secondary, the first fusion of the main medicine, or the first fusion of the secondary medicine, this order cannot be messed up! Wrapping the medicinal materials with aura, you can freely control the order of the fusion of several medicinal materials.

After a short time, the medicinal herbs in the Dan furnace completely melted and turned into liquid. It can be clearly seen that the liquid formed by the three medicinal herbs is mixed with more or less black impurities.

The next step is to strip these impurities out of the liquid.

This process is not difficult, but the difficult thing is the fusion between the medicinal herbs. Soon, Liu Xiaoxu peeled off all the impurities in the three-flavor medicinal materials.

Finally, it comes to the most important part of the fusion of medicinal materials.

This step is the most difficult.

During the day, Liu Xiaoxu's alchemy failed, and the problem was in the fusion link.

Liu Xiaoxu controlled the flame to keep the temperature in the furnace at a constant temperature. Then he controlled the two herbs of fire dragon incense and fiery flower, which had turned into liquid, and fused with each other.

There is a primary and secondary distinction between medicinal materials, and the order of fusion is in order. According to the different types of elixirs being alchemized, the order of their fusion is also different.

For example, to refine the Awakening Pill, you need to first fuse the Fire Dragon Incense and the Tranquility Flower with each other, and then fuse with the Ice Heart Grass.

There is no room for error in this order!

As the two flavors of medicinal materials fused with each other, only to hear a snort, the two flavors of medicinal materials boiled sharply, the temperature in the furnace rose sharply, and there were even wisps of faint green smoke coming out of the furnace.

Liu Xiaoxu hurriedly reduced the intensity of the furnace fire and tried to maintain the temperature in the furnace at a constant temperature.

This process lasted about half an hour, and finally the two herbs were successfully fused together.

But Liu Xiaoxu's face was not relaxed.

The fusion of the last herbs is the most difficult. Every time, Liu Xiaoxu is planted at the last step.

And where the problem is, he also knows that it is the fusion of the last herbs, he always does not control the temperature well, and the temperature in the furnace is either too high or too low, leading to the final failure.

Liu Xiaoxu took a deep breath, cheered up his spirit, and controlled the last medicinal herb of Bingxin Grass, fusing with the medicinal herb in front of him little by little.

Burst!

There was another strange sound in the Dan furnace that was unique to the fusion of medicinal materials, and the surface of the Dan furnace formed a faint layer of frost at a speed visible to the naked eye.

The temperature in the furnace fire is dropping dramatically!

The medicinal materials in the Dan furnace that were originally turned into liquid actually showed signs of solidification!

But at this time, the last herb has not yet been completely fused, once the herb solidifies, it will mean that the alchemy has failed! This is irreversible! The medicinal herb is solidified, and the medicinal properties inside will also be finalized, and the medicinal properties will be lost when they are returned to the furnace.

However, Liu Xiaoxu had already prepared and hurriedly increased the spiritual power delivery of the fire. The reason why the first two medicinal materials are fused, the furnace temperature rises, and the last herb is fused, and the furnace temperature decreases sharply, which has a lot to do with the medicinal properties of the medicinal materials. The fire dragon incense is hot, the flower is warm, the two medicinal materials are fused with each other, the medicinal properties are hot, and the furnace temperature will naturally rise. The ice grass is cold, so when the ice grass is fused, the furnace temperature drops sharply.

At this moment, Liu Xiaoxu was sending spiritual energy to the Dan furnace with all his might, and the furnace fire quickly became prosperous at a speed visible to the naked eye. Just this was not enough, Liu Xiaoxu injected several spiritual qi into the medicinal materials in the furnace one after another, and these spiritual qi were like spider silk, wrapping the medicinal materials layer by layer, more or less isolating a part of the cold qi.

After persisting like this for half an hour, the temperature in the Dan furnace finally rose and gradually stabilized, and there was a faint medicinal fragrance wafting out of the Dan furnace.

Liu Xiaoxu couldn't help but be overjoyed.

Medicinal fragrance is an important symbol of the success of the fusion of medicinal materials!

After an afternoon and an evening of hard work, he finally succeeded!

However, the presence of medicinal incense can only indicate that the fusion has been successful, and it does not mean that the refining of the elixir is over.

Finally, there is the cooling and forming of the elixir.

This step is also crucial!

Whether this step is done well or badly will directly affect the grade of the elixir. Only by allowing the medicinal properties to be perfectly sealed in the elixir and not lost outside, can the elixir be stored for a longer time and the grade of the elixir will be higher.

Liu Xiaoxu concentrated and did not dare to slack off.

With the passage of time little by little, under the continuous warming of the aura, the Awakening Pill gradually cooled and formed, and the medicinal properties were condensed in the pill, and only the medicinal fragrance emanated from the pill.

In the end, a wisp of light that was unique to the pill when it became a pill bloomed from the furnace.

Liu Xiaoxu let out a sigh of relief, and a relieved smile appeared on his face.

The Awakening Pill has finally been successfully refined!
