Wang Zifeng looked at the turbid liquid for a while, calmed down, patted his face, and cleaned it up.

Close the lower abdomen of the Dan furnace to prevent the long flame wood inside from touching the air and extinguish it, and then open the drain of the Dan furnace, drain the liquid medicine that cannot be used, put it in a bottle, and put it aside.

These medicinal liquids have now turned into medicine residue, and although they cannot be alchemized, they can be made into some poisons. Wang Zifeng didn't get the prescription for these poisons, but when he saw such a sentence in the instructions, he wrote it down.

Although the failure of alchemy is not a good thing, at least it can be recycled.

Keep these things and maybe you can use them later.

Wang Zifeng put the medicine residue away, took some water, and rinsed it in the medicine stove.

After a while, when the temperature went down, Wang Zifeng rekindled the Changyan Wood.

The water in the furnace evaporates quickly.

Wang Zifeng measured the temperature again and started alchemy again.

Although General Hu only provided one medicinal herb, this medicinal herb was enough for Wang Zifeng to refine thirteen times. If it weren't for the fact that there were only thirteen Cold Moon Lotus Seeds, the other medicinal materials would be enough to continue, and there would be no problem refining twenty times.

Now Wang Zifeng has wasted a Cold Moon Lotus Seed, and there are only twelve chances left.

According to his previous experience, Wang Zifeng refined the medicinal liquid and began to refine the medicinal liquid.

This is the second step of alchemy, refining the liquid into a paste.

The impurities in the liquid are forced out by the fire, and finally condensed into a paste.

The difficulty in this step is the control of the fire and the control of the medicinal properties.

Because the fire source used by Wang Zifeng is Changyan Wood, the firepower is stable, and no additional control is required, and all Wang Zifeng has a lot less trouble, and only needs to focus on the control of medicinal properties.

Even so, this step is not easy, mainly because the changes of yin and yang are too frequent, and there can be no gap.

Wang Zifeng was relaxed for a moment just now, and he didn't grasp the sudden change.

This time, Wang Zifeng absorbed the lesson, without a trace of omission, and finally got through this step.

The white liquid had now turned into a pale blue paste, revealing a hint of coolness.

Although the Dan furnace was still hot, the coolness of the ointment still made Wang Zifeng jīng shake and clear his mind.

The ointment has one-third of the medicinal properties of medicinal materials, and it is already a relatively common medicine, and many people who refine medicine will not continue to refine it into a pill, but use it directly, and the effect is also very good.

Wang Zifeng was a little moved, but when he thought of Qingxin Dan, he still didn't stop moving.

The chance of Qingxin Pill getting rid of heart demons is very small, and the chance of using ointment is even smaller, even if it is difficult to fight the quantity. This kind of thing that doesn't go up or down, forget it.

Having strengthened his belief, Wang Zifeng continued.

This time, instead of lengthening the flame wood, he pulled out a few from it to lower the temperature of the Dan furnace.

The third and final step of alchemy, refining the paste into a pill, does not require too high a temperature, it requires the rotation between yin and yang attributes.

This step is the most difficult, blocking the footsteps of countless people. Many people only refine the ointment and do not practice the elixir because they can't complete this step.

The first step in refining the Qingxin Pill is to control the changes in yin and yang on the cold moon lotus seed, so that it can be combined with the external medicinal liquid, so that the yin and yang can be fused, and there is yang in yin and yin in yang. It's already hard.

The second step is even more troublesome, it is necessary to stabilize the properties of the whole furnace liquid, to control the yin and yang changes of all the liquids, and to stabilize the yin and yang imbalance in every place, so as not to break the overall balance.

The third step is the difficulty of difficulties. It needs to break the balance that has been formed on the ointment, and at the moment of breaking, the yin and yang attributes will rotate to form a wheel that will automatically complete the condensation of the elixir.

What this step requires is no longer control, but a kind of mystical understanding, and the opportunity to turn the yin and yang attributes is inexplicable.

Some people have high comprehension and may succeed all at once, while others have low comprehension and may not succeed at all.

Experience can help far less than a flash of inspiration can bring.

Of course, experience is also useful, otherwise there would be no alchemists piled up with medicinal materials.

Although Wang Zifeng didn't want to become an alchemist who used medicinal materials, he didn't know how good he was in this area, so he could only give it a try.

At the moment of breaking the balance of yin and yang in the medicinal ointment of the Dan furnace, Wang Zifeng's eyes were concentrated, and his bright eyes were exerted to the extreme, and in an instant, he seemed to see the yin and yang attributes turned into filaments flying in the medicine furnace.

Wang Zifeng quickly controlled the internal force, pulled those filaments, and turned them in the medicine furnace.

Those filaments were affected by the internal force of Wang Zifeng and began to rotate, but they kept colliding and rotating.

Wang Zifeng controlled it several times in a row, and those filaments were still entangled.

Wang Zifeng could only reluctantly give up part of the filaments, separate some of the filaments that rotated more regularly, and gently plucked them.

Suddenly, a tangled filament rushed towards the filaments within Wang Zifeng's control at an incredible speed.

Wang Zifeng knew that it was the yin and yang of these filaments that began to rotate, forming a suction force that pulled the yin and yang attributes of those flocculents.

But at this time, most of his jīng power was on controlling the filaments that were about to succeed, and he couldn't distinguish the jīng forces from the tangled filaments.

But if he didn't deal with this entangled filament, he would fail again in alchemy this time.

As a last resort, Wang Zifeng could only decide to give up part of the filaments again.

Just as he had made this decision, the world in his eyes seemed to come to a sudden halt, and a dot appeared there on top of the tangled filament.

Wang Zifeng is blessed to the soul, and the internal force hits it, and it is in the middle of that point.

The tangled filaments jerked and began to spin wildly.

As it rotated, it became more and more round, and a suction rose from within it, sucking a stream of ointment from the Dan furnace and engulfing it.

As it swirled, those ointments quickly turned into a round pill, emitting a blue glow in the furnace.

At the same time as this pill was formed, the filaments that were almost hit by the tangled filaments also rotated into circles, inhaled some ointment, and turned into pills.

However, these pills are of different sizes and shapes, and the blue light on them is dim, almost none.

In addition, there were some ointments in the medicine furnace that had not been condensed into pills, but the coolness inside had long since dissipated, revealing a gray dead air.

These ointments also turned into residues.

Wang Zifeng didn't care about those medicinal residues at this time, but looked at the blue light pill and was excited.

Unexpectedly, his comprehension was good, and he actually refined a top-grade pill for the first time in alchemy.
