Han Tu had never studied alchemy, so he naturally didn't know anything about it. If it weren't for the fact that he had a bunch of useless garbage materials at hand, maybe he wouldn't have used Lian Shan to successfully refine Zhuji Dan for Shi Ding under impulse.

Now, what he needs to do is to use the five medicinal materials in front of him to test the specific effect of the high-grade magic weapon.

As a Dan furnace that does not enter the stream, Ziguangding does not even have a grade. It can be said that there is almost no other effect except for the practice of disciples who are just starting out.

Don't look at it as inconspicuous, but in fact, it can still play a certain role in amplification. After being infused with the spiritual fire, the flame of the Dan furnace will be transformed into a relatively milder purple fire, which can greatly increase the fault tolerance rate of the alchemist.

It can be said that the Purple Fire Ding and the condensate are the two most needed and important things for junior alchemists. The former can help refine the essence of the spirit grass, while the latter can help in the final step, condensing into a pill.

Han Tu stared at the beating purple fire in the Dan furnace, although he knew it well, without any experience, he didn't know the temperature of the flame, he didn't know the time, and he didn't know the resistance of the spirit grass. Under various prerequisites, it is impossible for him to successfully cultivate the elixir.

But deep down in his heart, there is still a trace of longing. After all, who wouldn't want to be one in ten geniuses?

As the purple fire continued to heat up, Han Tu's attention became more and more concentrated. While controlling the temperature, he also constantly felt the changes in the spirit grass. Feel the process of falling apart and reassembling into a liquid essence.

It's a pity that the good times didn't last long, and just when the essence was about to condense, it turned into ashes with a pop.

It's unrealistic to say that you're not disappointed at all, but it's okay to accept it.

Han Tu poured out the remnants of the ashes in the purple light tripod, and he kept thinking about it in his heart. This is the process of alchemy! It's like refining the mountain into a stone tripod, refining the three-point spirit grass into a pill, no matter how you think about it, it's too weird.

Since the alchemy failed, the next step is to see how the refining mountain ding performs.

Repeating the old technique, Han Tu repeated the previous operation, completing the action of putting the spirit grass and other materials into the Dan furnace. The difference is that this time, the target has been changed from the Purple Light Ding to the Refining Mountain Ding.

At the same time as the medicinal herbs were put in, Han Tu urged the spiritual fire to provide enough temperature for the Dan furnace. Next, let's see what kind of magic this mountain refining tripod is.

As the medicinal herbs were continuously refined, new spirit herbs were also put into it under just the right conditions. Gradually, a portion of the ingredients has been put in. At the same time, in Han Tu's blind spot, one of the feet suddenly lit up with a faint light.

Compared to the flames in the Dan furnace, this light was really small. But such a fragile light is endless, as if it will never be extinguished.

After it seemed like a whole copy of the material, Han Tu stopped thinking about putting it in, intending to see what would happen first. Perhaps because of the ability to become a pill, the time for this second refining was actually longer than when using the Purple Light Ding.

In the blink of an eye, the time for a stick of incense passed.

Han Tu was still very nervous, but after smelling a burst of danxiang, he breathed a long sigh of relief. It seems that this Dan has been practiced.

He took the Pure Heart Pill out of the Dan furnace and put it in his hand to examine it carefully. Although he had never seen the Pure Heart Pill, out of intuition, he still found at first glance that the quality of this Pure Heart Pill should belong to the worse one.

Han Tu casually put the pill into the porcelain bottle and looked at the remaining medicinal materials. Next, it's time to try refining three medicinal herbs at the same time.

Time flies, and when Han Tu comes back to his senses again, it is already half an hour later. This time the Dan incense is much richer than before, to be honest, after experiencing these two alchemies, I can successfully refine it for anyone who has no experience, and I can even refine the legendary Zhuji Dan that has been lost. Judging from this kind of point, it is enough to show that the probability of becoming a pill in this refining mountain is almost ten percent.

Because of this, Cheng Dan did not bring much joy to Han Tu. On the contrary, it was the tempting danxiang that made Han Tu's eyes shine.

Seemingly...... As long as you put more than three parts of medicinal materials at the same time, it is enough to make a top-grade elixir!

Han Tu held his cheek with one hand and fell into deep thought.

It's just a little strange, normally speaking, refining the pill requires the alchemist to make constant adjustments in other aspects according to the temperature of different spirit grasses, in order to ensure the successful cultivation of the pill.

But how did this refining mountain tripod refine the elixir by itself? Obviously, what he provided for it was only a little aura!

For a while, Han Tu couldn't help but think about the machine spirit. If there really is a self-aware machine spirit in this Lianshan Shiding, and this tool spirit also has a lot of Dan recipes, then it makes sense.

Thinking of this, Han Tu hurriedly bowed respectfully to the Dan furnace.

"I've seen the machine spirit seniors. ”

But even though Han Tu said this, the refining mountain ding still didn't have any reaction. Fortunately, no one else was present at this time, otherwise it would have been misunderstood whether Han Tu had mental problems.

Han Tu smiled slightly awkwardly, full of self-deprecation.

Then he remembered something else. While it was still dark, he planned to buy a few more copies of the Pure Heart Pill materials to try to refine different copies at the same time.

......

At this time, the old man in the spirit grass house was squatting at the door watching others play chess, looking intoxicated. But how can anyone who has cultivated to such a level not feel the presence of others?

Almost as soon as Han Tu stepped into this town, he felt it immediately. However, because I looked at the rise of the next issue, I didn't care about the former.

And Han Tu didn't mean to disturb the old man Yaxing at all. Since the other party is so fascinated and has plenty of time, why rush to this time?

"Eh, you stinky chess basket! If you go there, won't you be fine?"

"Phew, don't you accept you to play, don't you understand if you don't speak a game of chess?"

"I'll go down, I'll go down!"

The game ended with Kuroko winning, and the old man took the initiative to ask when he saw that Han Tu was still standing beside him, but he didn't bother himself at all.

"Do you want to sell or buy it?"

For Han Tu, there are only two possibilities, one is that all the materials are destroyed, and he is unwilling, so he wants to buy a few more materials to try.

And the second possibility is that after refining a few copies failed, he felt a little distressed about the spirit stones, so he planned to sell the remaining materials.

"What? I want to sell materials, right? The old man will make it clear to you first, this is not the same price as buying it if you sell it back!"
