"Start refining the pill, after such a long time of preparation, I hope the final result will not disappoint me."

Su Heng looked at the iron furnace in front of him that was slightly reddened under the licking of the flames.

There was a little excitement in his eyes.

The medicinal materials had already been carefully handled by Su Heng, just waiting for the heat to be about the same, and then add them to the alchemy furnace in order.

"Whew!"

Su Heng inhaled hard, and then blew towards the firewood.

The flames burned even more violently in an instant, rising to a height of half a person, completely enveloping the alchemy furnace. The iron, silvery-white alchemy furnace, under continuous heating, has taken on an orange-red luster, which is almost exactly consistent with the phenomenon recorded in the Longde Pharmacopoeia.

"Add Red Lingzhi first!"

Red Ganoderma lucidum is the main material in Qi and Blood Pill.

Even if the quality of this red lingzhi in Su Heng's hand is not too good, the price is also very expensive.

The palm-sized red lingzhi was chopped by Su Heng and thrown into the alchemy furnace, and the little water remaining in the red lingzhi was locked in the iron furnace and mixed with the medicinal herbs themselves.

Under the high temperature baking, it gradually turns into a mass of red clay.

Then add yellow essence to neutralize the medicinal properties of red reishi.

Finally, add the sage.

A medicinal herb was completely put into the alchemy furnace by Su Heng, and the rest of the time was to wait quietly.

When it was about the same time, Su Heng took the alchemy furnace out of the firewood pile, put it in the icy stream water to quickly cool down, and then opened the lid of the alchemy furnace with great anticipation.

As a result, not surprisingly.

Inside the alchemy furnace, there was a large black patch.

Obviously, it didn't condense into a pill and failed completely.

A pair of valuable red lingzhi medicinal materials were lost in this way.

"It should be that the heat is not well controlled, this is a bit troublesome..."Su Heng pondered where the problem appeared.

Let's be honest.

The process of refining the elixir.

It was far more complicated than Su Heng had imagined at the beginning.

Moreover, the process will be different depending on the shape of the furnace, the way of ignition, and even the climate.

In such a situation, if you want to refine into a pill, it is definitely not right to blindly follow the way recorded in the pharmacopoeia, and you must adapt to the situation and make reasonable changes at some key nodes.

Of course, in Su Heng's opinion.

The most important thing is still in many attempts, and luck.

"I have a full ten materials in my hand now, and I hope to be able to make Cheng Dan before they are all consumed."

Su Heng sighed silently in his heart.

I'm cheering myself up.

He looked at the black medicine residue left in the Dan furnace, but his heart was moved.

Stretching out his long thick fingers, he carefully dug out some of the medicine residue and put it in his mouth, and a bitter and dry taste suddenly spread in his mouth.

That taste.

So that Su Heng, who was used to eating all kinds of bitter medicines, couldn't help frowning slightly.

"It's hard to eat."

Su Heng rinsed his mouth with clear spring water, but his face showed joy: "However, there are still a lot of medicinal powers of red lingzhi and sage ginseng left in these medicinal residues, and if they are used as medicinal powder, the medicinal power should be about the same as a serving of Huanglong powder." ”

The medicine is three points poisonous.

The toxicity in the residue can even be as high as seven points.

A normal martial artist, even if he is short of money, will not find a way to use slag to assist his cultivation.

But Su Heng is different.

With the talent of eating immortals, he can basically be invincible to all poisons now.

The residual toxicity in the residue did not play any role to him. On the contrary, Su Heng could rely on the residual toxicity in the medicine residue to deduce where those problems might appear in the alchemy process.

Su Heng washed the remaining medicinal residue in the Dan furnace with boiling water.

After that, the Dan furnace is cleaned.

Start the second attempt.

"The reason for the failure last time was because the temperature of the flame was too high, and the temperature conduction effect of the iron Dan furnace was better than that of the copper Dan furnace, so the temperature control was slightly lower than that recorded on the Dan Fang."

Su Heng guessed that the reason was in the control of the temperature.

This time, he removed some firewood from the fire, lowered the temperature in the process, and then began refining the elixir again.

"Poof!"

Half an hour later.

Su Hengxing rushed to open the Dan furnace.

Inside was a pool of black, cloudy liquid with a rich, bitter taste.

"This time the temperature was too low, and the red lingzhi was not able to be completely cut, and I could even see the rhizomes of the lingzhi and sagetail ginseng."

"Don't let up!"

Su Heng cleaned the remaining medicinal residue in the alchemy furnace.

After drying.

Begin the process of refining the elixir for the third time.

After another half an hour, there was a slight popping sound from the alchemy furnace that had been heated to a dark red.

Su Heng used the cold spring water to quickly cool down the red-hot alchemy furnace, and then opened the lid. Not surprisingly, the refining of the elixir still failed this time, but compared to the previous two times, this time it has made great progress.

In the alchemy furnace.

On a large pile of black medicine residue, there were three or four black-gray clumps the size of little fingers.

Although it is far from being called a true Qi and Blood Pill, at the very least, the product refined this time already has some traces of the pill from the appearance.

In just one day.

Being able to make such progress was enough to make Su Heng feel happy and satisfied.

Su Heng took out the remaining lumps in the Dan furnace, such lumps had a crispy appearance and a rather unstable structure, and they would completely disperse with a little force.

Raise your head and swallow it in your mouth.

A faint medicinal power exploded in Su Heng's mouth.

"Although it can't be called a real pill, the medicinal power of the three-point qi and blood pill has already appeared in it, which can play a certain role in promoting cultivation."

Su Heng had taken many Qi and Blood Pills.

Compare at this point.

Soon found out the problem with these pills, he was not discouraged, after all, he was only a beginner, and it was quite remarkable to be able to refine this level of waste pill in one day without guidance.

If it gets out.

It will stun many people's jaws and make some old alchemists who have been famous for a long time feel ashamed.

Su Heng understood the principle of step-by-step, so after making satisfactory progress, he did not force himself too hard.

The rest of the time.

It was used by Su Heng to practice Hong Xiang Fist and Dragon Claw Gong.

As early as more than half a month ago, the Dragon Claw Gong had been cultivated by Su Heng to the point of small success, and now with the pouring of a large number of resources, the cultivation progress of the Dragon Claw Gong is also rapidly improving.

It won't take long.

Su Heng was able to cultivate the Dragon Claw Gong to the fullest and complete the second blood refining.

That's it.

In a blink of an eye, half a month has passed.

Su Heng carefully opened the lid of the alchemy furnace in front of him, a wisp of fragrant smoke rose up, and seven or eight round pills with dark red body surfaces lay quietly in the Dan furnace.

"Cheng Dan!"
