Zhenbao Zhai, after many days, Du Long and Xia Qinglian came to this golden cave where ordinary people are afraid to walk again, and after the two came back from Lingyun Mountain, they didn't even return home and came here!

The clever waitress happened to not accompany the other guests, and when she saw the two of them entering the treasure house, she hurriedly greeted her warmly: "Childe, I came to the treasure house today, but what treasures do you want to buy?!"

Smiling and nodding, Du Long was naturally willing to let this clever waitress accompany him, the purpose of this trip was clear, he didn't wander around in the treasure house, and said directly: "I want to buy three spiritual herbs for refining a grade of spiritual liquid, last time I saw the price, it should be sixty or thirty hundred gold coins, right?!"

"That's right! The elixir for refining a grade of spiritual liquid is two hundred and ten gold coins each, and if three parts are used, it will be a total of six hundred and thirty gold coins," the clever waitress replied with a smile.

"Well, this is seven hundred gold coins, you go and help me go through the formalities!" Du Long didn't talk nonsense, and directly took out the last seven money tickets on his body and handed them to her.

"Okay, Childe, please go to the lounge and sit down for a while, and handle the formalities for you right away!" Pleasantly surprised to receive the seven money tickets, the clever waitress hurriedly stretched out her hand to lead Du Long and Xia Qinglian to the side of the lounge to sit down.

Soon, the waitress who had completed the formalities came back with a package and a bag of gold coins: "Childe, this is a spiritual liquid medicinal material you bought, a total of three copies!

Unceremoniously took the two bags, Du Long directly opened the package containing the medicinal herbs, and after confirming that the elixir he bought was correct, he didn't go to count whether the gold coins in the other bag were sufficient, and stood up directly and said goodbye to Xia Qinglian and left.

The clever maid who sent Du Long and the others out of Zhenbao Zhai all the way looked at the back of them leaving, and muttered secretly: "This son is estimated to have helped a certain pill pharmacist buy medicinal materials, and he is really a lucky son to be able to know a pill pharmacist!"

After returning to the mansion and having dinner with his parents and others, Du Long and Xia Qinglian returned to their respective rooms, bolted the door tightly and went to bed.

Sitting cross-legged on the bed, Du Long's mind sank into the dantian space, and soon found his own Huoyunding in the qi eye in the middle of the cyclone!

Originally, he included Huoyunding in the space of the Snake Ring, but the beauty of the Ring Spirit reminded him that Huoyunding had been recognized as the master, and it was best to put it in the dantian space and conceive it in the dantian fire!

Du Long, who was convinced of the beauty of the ring spirit, naturally put Huoyunding in the middle of the dantian cyclone according to his words, and put it together with the flames in the qi eye, so that the dantian Ganghuo continued to give birth to Huoyunding!

As soon as his mind moved, Huo Yunding appeared on the palm of his left hand, and with his right hand, he opened the package at the head of the bed, and collected all the elixirs in it into the Huoyun Ding space.

Huoyunding space is used to store elixir, and the medicinal properties of elixir are more difficult to be volatilized and wasted, it is really an excellent place to hide elixir, of course, in front of outsiders, he can't reveal the secret that he has a space memory.

His mind sank into the Huoyunding space, and began to classify and arrange a bunch of elixirs, refining pills is meticulous work, and there is no room for mistakes, he needs to deal with all the details well, and try not to make mistakes in the process of refining pills as much as possible!

He carefully reviewed the prescription of the first grade of spiritual liquid medicine in his mind, what he needed to pay attention to during the refining process, and after feeling that there was no more problem, he began to transfer the Ganghuo into the fire cloud space.

Controlling the flames, the temperature keeps changing with his mind, this fire control process is also a warm-up exercise before refining the medicine, until he feels that he can control the flame freely, then he controls the taste of the auxiliary elixir to enter the flames and start his first elixir refining!

Disheveled!

In the flames, an auxiliary elixir called Ice Heart Grass suddenly turned into ashes, and quietly drove the impurities of Ice Heart Grass that turned into ashes away from the Fire Cloud Space, and Du Long continued to throw another Ice Heart Grass into the flames.

This kind of mistake in the process of refining the elixir is normal, and Du Long has long been used to it!

This time, the heat was properly controlled, and Du Long successfully refined the Ice Heart Grass into a pale cyan spiritual liquid, so he controlled a wisp of Gang Fire to continue calcining the impurities at a stable temperature, and then continued to put the flavor auxiliary herbs into the Gang Fire.

There are five flavors of the whole nine flavors of auxiliary elixirs, although these elixirs are very close to the refining point of ordinary medicinal materials used for hand practice, but there are always some differences, and this difference has to be carefully experienced by the pharmacist himself.

You can only understand it, you can't pass it on in words, you can rely on personal experience, which is a major feature of the inheritance of Dan Yaoshi!

Time passed, with five failures, Du Long finally got nine successes, nine colorful elixir liquids, under the roasting of the fire, kept squirming, and the brakes were beautiful.

Finally, when he reached the stage of refining the main elixir of a grade of spiritual liquid, he threw the hundred-year-old silver ginseng into the fire without hesitation, and controlled the flame temperature that he thought was the most suitable in his heart like refining wild ginseng, and suddenly completely wrapped the century-old silver ginseng.

Disheveled!

Elixir refining, there is a critical point, beyond the critical point, it will cause deflagration, the elixir will be burned to ashes on the spot, most of the elixir refining can slowly control the flame temperature to find the critical point of the medicinal materials, but the hundred-year-old silver ginseng is not.

If you slowly control the flame to find the critical point, the medicinal liquid inside the century-old silver ginseng will not be forced out quickly, and finally coagulate with the impurities inside the medicinal materials, then the main medicine will be ruined!

Looking at the hundred-year-old silver ginseng that turned into ashes, this is an expensive medicinal material with more than 100 gold coins, and more than 100 gold coins will be burned with a fire, the corner of Du Long's mouth twitched a little painfully, and he could only force down the pain in his heart, drive the impurities out of the space, and throw another century-old silver ginseng into the flames.

With the experience of the previous failure, Du Long controlled the flame to lower the temperature than before, and then suddenly wrapped the second flavor of the century-old silver ginseng abruptly!

Phew!

The hundred-year-old silver ginseng trembled suddenly, and quickly withered, the speed of withering was obviously a little faster, and a large amount of elixir liquid was forced out of the surface of the ginseng body, knowing that the temperature was still a little high, Du Long was busy controlling the flame and lowering the temperature a little.

With just such a slight temperature difference, the speed of the liquid exuding from the surface of silver ginseng has dropped significantly, reaching a relatively normal level!

Multiply...... Multiply......

The process of forcing out the liquid medicine at this high temperature was very fast, and the hundred-year-old silver ginseng finally no longer had the liquid medicine discharged, in order to turn into a dead branch, it was instantly driven out of the fire cloud space by Du Long, leaving only a milky white liquid in place, and from time to time there were bubbles to release impurities.

Control the flame to start cooling, then observe the changes in the liquid medicine to determine the optimal temperature to stop the cooling, and maintain this temperature until no more impurities are discharged!

The most difficult steps were completed, Du Long looked at the ten balls of elixir liquid that no longer had impurities discharged from the flames, and according to the combination method suggested by the prescription of the first elixir, he threw the nine elixir liquids into the main elixir liquid in order, and controlled the flame of the roasting main elixir liquid to heat up suddenly!

The milky white main elixir sometimes turns green, sometimes turns green, every time you put in an auxiliary elixir liquid, a change will occur, when the last auxiliary elixir is put in, Du Long raised the flame temperature again, a large mass of elixir liquid boiled wildly, all kinds of elixir liquid under the high temperature cautery, quickly underwent some qualitative change!

The originally colorful medicinal liquid turned bright white in the continuous boiling, and Du Long controlled the flame to cool down evenly, and slowly moved away from this bright white medicinal liquid.

As the temperature dropped, the liquid medicine that was constantly boiling and squirming gradually calmed down, and in just a few moments, the whole liquid shrank by more than half compared to just now!

Finally, as the flame moved away from the medicinal liquid, a bright white liquid that no longer wriggled appeared in front of Du Long, which was the standard first-grade spiritual liquid form - bright white!

Call!

With a long exhalation, Du Long opened his eyes, turned his hand and took out a jade bottle, put the bright white first-grade spiritual liquid that suddenly appeared into the bottle and closed the lid.

Du Long had no idea what kind of miracle he had created!

In the entire Haotian Empire, no, it should be said that in the entire Star Continent, and even in this world, there is not a single little guy who has only reached the cyclone level who can refine the elixir!
