Qin Hao smiled and did not answer Gongsun Yao's words. Qin Hao searched through the space ring and found out a stone, which looked like a large pushpin. However, the center of the pin is hollow.

Under Gongsun Yao's curious gaze, Qin Hao stuffed the stone into the earth fire pipe. Qin Hao closed the top lid of the alchemy furnace and used his spiritual power to open the valve of the earth fire again. With a pop, earth fire gushed out of the earth fire pipe again.

Qin Hao spread his hands and made a gesture of please. Gongsun Yao input her spiritual power into the alchemy furnace, and then she grew up with a small mouth! This Mr. Qin really did it! There really wasn't a single impurity in the earth fire!

"It's amazing, how did Mr. Qin do it?" Gongsun Yao was dazzled.

"It's the work of that stone that it can absorb most of the earth's qi, only methane won't. Even if I explain the exact principle, you won't understand it, unless you become an expert in chemistry. ”

"It doesn't matter if you don't understand, Mr. Qin, can you let me play with this stone for a few days?" The stone in Gongsun Yao's mouth was naturally the one at the bottom of the alchemy furnace.

"I've sent you, I have this stone. ”

"Thank you, Mr. Qin. Gongsun Yao's gaze softened, although Qin Hao said it very casually, she could see a hidden pain flashing in Qin Hao's eyes.

Qin Hao smiled, and then focused his attention on the alchemy furnace. Fire testing is the first step of alchemy, and the second step is the furnace, different alchemy furnaces require different temperatures to warm the furnace. Qin Hao could see at a glance that Gongsun Yao's alchemy furnace was made of smelting Heavenly Crystal Sand and Thousand Sections of Earth.

Tianjing sand and Qianduan soil have strong heat resistance, so a higher temperature is required when warming the furnace. In Qin Hao's warm furnace, Gongsun Yao has been observing with her spiritual power, and she wants to see if Qin Hao really knows how to make alchemy.

Finding that the temperature in the Dan furnace exceeded 1,000 degrees, Gongsun Yao frowned tightly: "Mr. Qin, the temperature of the furnace is a little too much, isn't it? Although the heat resistance of Tianjing Sand and Qianduan soil is better, it is okay to have 800 degrees, right?

Qin Hao smiled and patiently explained: "If you use medicinal materials for purification, it is indeed eight hundred degrees that is enough, but now it is medicinal residue that is used for purification. These medicinal residues are formed by the fusion of many kinds of medicinal essences, and there have been some abnormalities in the medicinal properties, so it takes a temperature of more than 1,500 degrees to refine all the medicinal essences. Therefore, I will heat it for a while, and I will not waste the energy of the ground fire, nor will I waste these residues. ”

Gongsun Yao nodded thoughtfully, alchemy with medicinal residue, this is the first time I have seen it with my own eyes, and some things are different from normal alchemy. Gongsun Yao no longer bothered Qin Hao's alchemy, and patiently observed it with his mental power.

Qin Hao took a deep breath and violently opened the top lid of the alchemy furnace! Poof, a wave of heat came out, and the temperature of the entire side hall instantly increased a lot.

The heat wave was coming, and Bi'er subconsciously took a few steps back. And Gongsun Yaoquan was not afraid of the heat wave, not only did not retreat, but took a few steps forward.

Qin Hao picked up the small bucket containing the medicinal residue and poured all the medicinal residue into it from the entrance of the medicinal materials of the alchemy furnace. Seeing this scene, Gongsun Yao's eyes narrowed, when it was normal to purify, it was to distinguish and refine various dispensings separately, but now that the medicinal essence of the six ingredients is all combined, the difficulty must have increased greatly.

Qin Hao once again sank his spiritual power into the alchemy furnace, constantly increasing the output of the earth fire, and when the temperature of the earth fire was close to 1,200 degrees, Qin Hao stopped heating up. Qin Hao felt that the medicinal essence of the medicinal herb with the lowest melting point had been refined.

After a quarter of an hour at a temperature of 1,200 degrees, the medicinal essence no longer appeared on the medicinal residue, and Qin Hao carefully collected the medicinal essence floating in the medicine pod.

Then, Qin Hao continued to raise the temperature, until it reached 1,350 degrees, the second medicinal essence was refined, and after half an hour, there were six more groups of medicinal essence in the alchemy furnace.

Qin Hao shook his head gently: "It's a pity that these third-order medicinal materials are raw materials, if you don't lose some of the medicinal essence, there will be more medicinal essence refined, and you should be able to succeed in six Ning Dan, and the quality will be higher, and you should be able to reach the third-order best." ”

It's a pity, it's a pity that you have a face! At this time, Gongsun Yao was already sluggish, this is simply unscientific! There were six groups of medicinal essence floating in the alchemy furnace! The quantity and quality of these six groups of medicinal essence far exceeded the medicinal essence he had once refined!

You must know that when she purified it, she used intact medicinal materials, and the purified medicinal essence was only worthy of reaching the third-order middle grade, while Qin Hao used medicinal residue, but the medicinal essence he purified had already reached the third-order upper grade!

Also, the medicinal essence purified by Gongsun Yao can be at most three pills, and the number of medicinal essences purified by Qin Hao can be at least five pills!

Do you want people to live? This Mr. Qin is simply a monster! I don't know why, Gongsun Yao suddenly had a strong feeling, perhaps, he won't die! It's just that if he is committed to this Mr. Qin, what should he do with the who can communicate with his heart?

Qin Hao was a little dissatisfied with the Guo Qin he had purified, and after imprisoning the six groups of medicinal essence, he controlled the reflux of the ground fire, and the medicinal residue in the alchemy furnace slowly solidified. At this time, the residue looks more like the real residue, dry, and can barely squeeze out water.

But in Qin Hao's opinion, there are infinite possibilities for these dry dregs. I remember that his cheap master once said that medicinal essence is like a woman's breasts, and there will always be a squeeze!

Feeling the rapid drop in the temperature in the alchemy furnace, Gongsun Yao was a little confused, and asked hesitantly, "Mr. Qin, why do you want to cool down?

"The purification just now was a bit incomplete, so I'll purify it again. Qin Hao replied truthfully.

What? No...... Not thorough? This is not complete? Do you want to be so shocking? For a long time, Gongsun Yao thought that her alchemy skills were outstanding, but now, Gongsun Yao even had a very strange idea, she didn't know how to do alchemy at all!

If it weren't for Qin Hao's first refining strength, I'm afraid Gongsun Yao would have squirted Qin Hao with blood. These medicinal residues are not very effective when they are flower fertilizers, how can they purify some medicinal essences?

Although his mind was full of question marks, Gongsun Yao was stunned to hold back the confusion in his heart, and watched Qin Hao's every move with his mental power.

When the temperature dropped to eight hundred degrees, Qin Hao increased the earth fire valve again, and the temperature in the alchemy furnace began to rise again. The temperature soon reached 1,200 degrees, which was the melting point of the lowest melting point of the kind of dispensing, and a small residue in the residue quickly liquefied and became liquid.

However, that kind of shiny medicinal essence did not appear. I don't know why, seeing Qin Hao's failure, Gongsun Yao breathed a sigh of relief, it seems that this man is not so omnipotent!

Just when Gongsun Yao had just breathed a sigh of relief, she felt that Qin Hao had violently increased the output of her spiritual power! The super strong spiritual power almost crushed her spiritual power! Gongsun Yao's heart sank, and she hurriedly increased the output of her spiritual power, which stabilized her spiritual power.

Gongsun Yao was amazed, this Mr. Qin was about the same age as himself, why could his spiritual power be so strong? Just by affecting it, he almost wiped out his spiritual power! It's just that why did he suddenly increase the output of his spiritual power?

Soon, Gongsun Yao understood Qin Hao's intentions, and after increasing the output of spiritual power, the pressure in the alchemy furnace suddenly increased several times!

"It's really refined! It's really refined medicinal essence!" Even though Gongsun Yao's tutor is excellent, she can't help but exclaim! In her eyes, the medicinal residue that has been purified once has no value as fertilizer, but Qin Hao can squeeze out the medicinal essence stiffly! This is also too against the sky!

Half an hour later, six small groups of medicinal essence were purified from the residue again. Qin Hao nodded with satisfaction: "Yes, this should be able to successfully condense six pills, and two of them should reach the level of third-order best." ”

Gongsun Yao doesn't know what to say anymore, she can't describe the shock in her heart in words!

After the temperature of the alchemy furnace slowly decreased, the liquefied medicinal residue slowly solidified, and then scattered like dust, lying calmly at the bottom of the alchemy furnace.

Gongsun Yao's gaze was in a trance for a while, it turned out that the real medicine residue was like this! It was almost like completely burned out charcoal ash, which could be dispersed with the wind!

"I really didn't expect that these so-called medicinal residues can be completely reused, how many medicinal materials have I wasted before!Mr. Qin, can I turn liquid now?" After a short shock, Gongsun Yao slowly came back to his senses.

Qin Hao nodded: "It's best to do the liquid and Ning Dan in one go, otherwise it will be easy to fry the furnace when Ning Dan." If I'm not mistaken, the girl waited for a quarter of an hour before she started to condense the pill after the liquid was successfully transformed just now. Could it be that when she was alchemy just now, the girl was always restless?"

Of course, I was uneasy, just now Gongsun Yao's heart was full of the man who played with her piano and flute, where could I concentrate my attention? Of course, Gongsun Yao would not admit it: "The little woman's mental strength is a little weak, so she delayed for a while." ”

Qin Hao shrugged, not interested in asking, and focused his attention on the alchemy furnace. In just an instant, Qin Hao eliminated all his selfish distractions, and only the six clusters of medicinal essence floating in the alchemy furnace were left in his world.

The so-called liquid is to let these six groups of medicinal essence fuse together. However, the melting and boiling points of each medicinal essence were different, so Qin Hao needed to use his spiritual power to divide the Dan Furnace space into six different areas.
