Refining the Pulp Cleansing Pill is not only complicated, just the medicinal materials required for refining, there are as many as fifty-three, once the proportion of the configuration is slightly wrong, it will lead to failure in an instant, which shows how difficult it is to refine.

Fortunately, Tang Feng had already had the experience of refining the Qi Gathering Pill before, and he had a little experience.

And the main thing is that there is one more bottle of ambergris, and even if he fails a few times, he can afford to lose it.

In addition to the large bags of medicinal materials on the table, there is also a three-legged Ding furnace in the inner room, according to the information on the Dan Fang, the ancient alchemists have their own special Dan furnace, and there is also a Dan fire that matches their own qi attributes.

Only the most suitable Dan furnace and sufficient heat can ensure the success rate of Dan medicine to the greatest extent.

It's just that for Tang Feng, a self-made man, not to mention the legendary Danhuo, even the Ding furnace is just an imitation that Mao Eighteen picked up from the market.

As for Danhuo, there is really no way, so it is replaced by modern firearms, but fortunately, this tool is easy to master, and the fire is easy to control, Tang Feng saved a big trouble.

According to the introduction of the alchemy procedure, the first process is meditation, and the alchemist needs to abandon his distracting thoughts and calm his mind before he can proceed to the next step.

He immediately sat down cross-legged, adjusting his breath until his mind was completely calm, and then he got up.

The second step is to ascend to the tripod, Tang Feng's right hand was gently raised, and the energy gushed out, and the simple shape of the tripod furnace in front of him immediately jumped on the fire frame.

This was followed by the lighting of the fire......

Refining the pill is undoubtedly an extremely patient and careful project, Tang Feng did not dare to be careless, and completely according to the record of the pill, step by step and orderly put the medicinal materials into the Ding furnace.

Although ambergris water is the last process to be put into the process, but several times in a row, Tang Feng did not use it, after all, this ambergris water is too precious, although there are currently two bottles, it is still far from enough.

In comparison, the rest of the medicinal materials, such as centennial Ganoderma lucidum and ginseng, are also precious, but they are not as good as this ambergris water.

Therefore, Tang Feng went back and forth, until he practiced the process and technique of putting medicinal materials in front of him to a very proficient level, and then he was officially ready to start.

The firearms under the fire frame had spewed out raging fire, and the copper Ding furnace had even been burned red, and every time Tang Feng put in a medicine, it immediately made a sizzling sound, and the Ding furnace was steaming white.

Until all the drugs in front of me are put in, everything is still under control, and everything is normal.

Tang Feng suddenly took a long breath, suddenly reached out and picked up the small half cup of ambergris that had already been prepared next to him.

Until now, he had not figured out what this ambergris was, and according to ancient rumors, it seemed to be the saliva of a rare beast or a dragon, but this legend could not be verified.

Fortunately, Tang Feng was too lazy to be elegant, his eyes were fixed, and he shook his hand and poured the small half cup of ambergris into the Dan furnace.

With the influx of ambergris, under the scorching flames below, the various medicines in the furnace began to quickly fuse and condense into a clump.

Tang Feng controlled the heat while staring closely at the changes in the furnace.

Seeing that under the action of ambergris, various medicinal materials fused sharply, and vaguely became the shape of the pill, wisps of pungent aroma overflowed into the pill furnace, filling the entire room.

Even Mao Shiba, who was sitting on the threshold, had already smelled this fragrance, and after being slightly stunned, he immediately said with great joy: "It seems that the pill is about to be completed!"

When he said this, his whole body could hardly hold back, and he trembled slightly.

However, at this moment, the Dan furnace inside suddenly exploded without warning.

With a click, the big cigarette stick in Mao Shiba's hand suddenly fell to the ground, and the originally excited heart also sank with the cigarette stick that fell to the ground.

"Did you fail, I don't know if there is a chance?" Mao Eighteen muttered, looking more anxious than anyone else.

He couldn't help but be anxious, after all, whether Tang Feng succeeded or not tonight was directly related to whether his strength could be restored, for a martial artist, there was almost nothing in heaven and earth that could compare to his own strength.

Compared with Mao Shiba's nervousness, Tang Feng in the room was still calm at this moment, his sword eyebrows were raised, and a pair of eyes stared at the thing in the furnace that had been blown into a black mass without blinking.

Tang Feng knew very well in his heart that he was obviously about to succeed just now, but at the moment when the pill was about to condense successfully, because of his excitement, his mood fluctuated, so that the heat was also fluctuated.

It was precisely because of this small mistake that the Dan furnace exploded, and finally fell short.

"It shouldn't be......" Tang Feng couldn't help but shake his head and smile bitterly, he originally thought that his heart was calm enough, but now it seems that it is far from enough.

But after figuring out the key, with the lessons learned this time, Tang Feng believes that he will never make the same mistake again next time, and he will definitely be able to do better this time.

Quickly cleaned up the dregs of the Dan furnace, Tang Feng rose to the top again, and then lit a fire.

Everything was going on in an orderly manner again, and as he threw the herbs into the Dan furnace, time passed little by little, and the sky was already white, and the bright sunlight shone through the window, and he was still unaware.

I don't know how long it took, Tang Feng reached out again and pinched the same amount of ambergris, and with a flick of his wrist, the turquoise ambergris water was immediately thrown into the Dan furnace.

There was another stabbing sound, and the Dan furnace once again erupted with a rolling heat wave, and a rising white mist surged.

Tang Feng suppressed the fluctuations in his heart, and through the heavy white mist, he saw that the various medicinal materials in the furnace were rapidly merging and condensing into a clump.

Wisps of pungent medicine rushed out, and as the firearm continued to burn, removing the dregs in it, the medicine mass became smaller and smaller.

Suddenly, the golden light was magnificent, and a dazzling golden light poured out from the Dan furnace, and under the illumination of these golden lights, the sunlight in the room seemed to be eclipsed.

The billowing aroma poured out of the room, filling the courtyard.

Mao Shibai naturally smelled this medicinal fragrance, and with another click, the big cigarette stick made of pure gold in his hand fell to the ground again, his whole body trembled again and again, and his old face was even more excited with tears.

"It's done, it's finally done, the legendary marrow cleansing pill has finally been practiced!" Mao Eighteen kept shouting, looking as if those poor children had suddenly gotten a piece of candy.

This time, Tang Feng could not hide the excitement in his heart, he practiced and practiced repeatedly for a long time, and finally succeeded, at this moment, in the Dan furnace, five pills that exuded a dazzling golden light like the size of a soybean were spinning there.

This is the legendary Purifying Pill, which is rumored to be able to help people wash the essence and cut the marrow, with a high probability of helping the martial artist, break through the entrance of the inner vein, and successfully enter the magical elixir of the Pulse Opening Realm.
