Chapter 292: Refining Failure

It seems to be the demon essence that Qin Lang obtained in the demon domain!

The demon heart marrow born from the demon king's heart condensing the aura of heaven and earth after the demon king's death already had a trace of simple wisdom, feeling the earth fire on Qin Lang's palm, it knew that it was not good, and it struggled desperately to escape from Qin Lang's palm.

However, no matter how hard it tried, it could not escape the shackles of layer after layer of spiritual power!

Qin Lang had already taken out the Spirit Weapon Pill Furnace, opened the lid of the furnace, put the Demon Heart Marrow on it, and with a stroke of the palm flame, an inch-long crack appeared on the surface of the Demon Heart Marrow, and silver blood gushed out from the crack, and all of it instantly dripped into the Spirit Weapon Pill Furnace.

Refining Erdan does not require all the demon heart marrow, but only needs the silver blood in the demon heart marrow.

However, refining once will consume all the silver blood of the demon heart essence to be effective, so for Qin Lang, if he wants to successfully refine the special grade Erdan, he only has this one chance!

So there must be no failure!

Putting the remaining part of the demon heart into the storage ring, Qin Lang took a deep breath, trying to keep his mood calm, and then urged the red flame earth fire to rush to the bottom of the spirit weapon pill furnace.

"Poof!"

A light sound came out, and the red flame directly enveloped the Dan furnace, and the temperature of the Dan furnace rose sharply under the churning of the red flame, and the temperature in the entire secret room also began to rise sharply.

"Zizi!"

Soon, the silver demon heart marrow blood in the Dan furnace began to boil, constantly bubbles, tumbling in the Dan furnace, making an extremely regular sound.

This is a manifestation of the silver blood of the demon heart marrow beginning to be refined.

The temperature of the Red Flame Earth Fire is extremely high, but the speed of refining the Demon Heart Marrow Silver Blood is still extremely slow, and if it is replaced by an ordinary flame stone, it is probably impossible to refine it at all!

It took a full hour for Qin Lang to refine all the demon heart marrow silver blood, and another hour to continuously purify it until he reached the limit he could reach, and then Qin Lang began to refine the next spirit grass.

Swallowing several fourth-grade special grade Qi Rejuvenation Pills that he had refined before, Qin Lang didn't bother to wipe the beads of sweat rolling down his sideburns, and continued to carefully control the temperature of the Red Flame Earth Fire to purify the spirit grass.

A spirit grass has been purified successfully!

The two spirit grasses were successfully purified!

......

All fifteen kinds of spirit grass have been successfully purified!

It took another hour for Qin Lang to finally purify all the remaining fifteen spirit grasses!

After the purification is completed, the next step is fusion!

Compared with purification, the difficulty of fusion is dozens of times greater!

After all, each spirit grass has its own medicinal properties, and it is difficult to fuse all the spirit grasses with more than a dozen different medicinal properties together, especially if there is a natural treasure such as the demon heart marrow!

According to the order of the Dan Fang, the two purified spirit grasses were carefully fused together, and the temperature in the Dan furnace was carefully controlled by controlling the red flame earth fire, so that the two spirit grasses could slowly adapt to each other's medicinal properties and gradually fuse together.

After the fusion was completed, Qin Lang once again wrapped the third purified spirit grass with his soul power and began to fuse.

......

With the passage of time, the fifteen spirit grasses were finally fused, and the next step was the last and most difficult step of the fusion—the complete fusion of the demon heart marrow silver blood purification with the previous fifteen spirit grass fusion liquids!

"Zizi!"

Concentrate on wrapping the demon heart marrow silver blood with soul power, and slowly inject it into the spirit grass fusion liquid, and the sound of "Zizi" came out in an instant, a large amount of white gas continued to come out, and the powerful air pressure made the top of the Dan furnace lid sound straight!

Qin Lang was shocked!

Once the lid of the Dan furnace is opened, air rushes in, destroying the temperature and composition in the Dan furnace, and the medicinal materials in the furnace will be wasted!

Once the medicinal materials are wasted, he won't have a second demon heart essence to refine the Erdan!

"I can't open it, press it down for me!"

Gritting his teeth, he used his soul power to the extreme, tightly wrapped the spirit grass mixture and the demon heart marrow silver blood, and constantly guided the generated white qi out of the exhaust groove!

The spirit grass fusion liquid seemed to be very afraid of the demon heart marrow silver blood, once it touched it, it quickly retreated backwards, and under Qin Lang's struggle to suppress it with soul power, it gradually quieted down, slowly fused with the demon heart marrow silver blood, constantly tumbling in the Dan furnace, and then completely fused with each other and fused evenly!

"Finally the fusion has been successful!"

Qin Lang's clenched heart relaxed slightly, and after the fusion, it was the last step of alchemy!

As long as the next condensation pill is smooth, Qin Lang believes that the grade of the Turning Pill he has refined can definitely reach the top level!

"Fortunately, I used the spirit weapon Dan furnace I got from Shi Wenhai, otherwise after such a long time, I am afraid that the ordinary Dan furnace would not be able to support the explosion furnace for a long time, and I would probably be depressed to death at that time!"

Glad to smile, Qin Lang was about to concentrate on Ning Dan, when suddenly a crisp voice came into his ears.

"Click!"

In Qin Lang's frightened gaze, which widened more and more, he saw a thin invisible crack appear on the top of the Spirit Weapon Dan Furnace, and with the scorching of the Red Flame Fire, that crack was gradually getting bigger and extended!

Even if it is a spiritual artifact furnace, under the continuous scorching of the red flame for several hours, it finally can't hold on and cracks begin to appear, I'm afraid it won't be long before the furnace will burst!

"How so!"

Qin Lang was shocked, once the furnace exploded, he was about to become a Dan, and the Erdan would be destroyed!

"No, we must speed up, and the condensing pill will be successful before the furnace is exploded, and the Erdan will be refined!"

Suppressing the shock in his heart, Qin Lang pushed the Red Flame Earth Fire to the extreme, and frantically sacrificed his soul power to wrap the fusion liquid in the Dan furnace and constantly tumbled and condensed in the Dan furnace!

At this moment, on the one hand, Qin Lang not only had to eliminate the interference of the imminent rupture of the Dan furnace and concentrate on the condensing pill, but on the other hand, he had to use all his resources to race against time, striving to successfully refine the Turning Erdan before the furnace burst!

Under the scorching heat of the red flame, the soul power wrapped in the fusion liquid bore the brunt of the crazy scorching, and bursts of intense pain penetrated into his mind, if it weren't for the hard support of the last thought in his heart, I'm afraid Qin Lang would have been unable to bear this torment and faint.

"Click!"

As time passed, the crisp sound became louder and louder, and the cracks on the Dan furnace also spread rapidly, spreading, and soon almost covered the entire Dan furnace like a spider web, making people worry that it could burst at any time!

"Danxiang!"

In the Dan furnace, you can already clearly see the condensed Ning Dan, and at the same time, a faint fragrance comes out of the Dan furnace, wafting in the room, and into Qin Lang's nose!

Qin Lang's face was overjoyed, and the fragrance of Dan came out, which meant that he was about to become a Dan!

"Bang!"

However, at the moment when a smile just appeared on Qin Lang's face, a loud noise came out, and the spirit weapon pill furnace, which had already become a spider's web, finally couldn't support it, and exploded violently, and countless fragments flew everywhere!

A burnt smell instantly came out of the shattered Dan furnace!

"Did you fail......

Looking at the blackened slag in the ruins of the Dan furnace in front of him with a lonely expression, Qin Lang instantly fell into an ice cellar!
