Old man Huang still didn't tell Ye Zi the reason in the end.

In the evening, after hanging a sign of retreat outside the courtyard gate, Ye Zi sneaked into the jade pendant space.

When Xiaotong and the others saw her come in, they immediately happily surrounded her, chattering non-stop. Ye Zi could see that the two of them had stayed here for a long time, and they were also lonely.

She suddenly felt that in this way, the two of them kept planting herbs, in fact, she couldn't use them up at all, and she didn't lack spirit stones for the time being, so it was better to let the two of them go, let the space be temporarily deserted, and only plant a small amount of rare spirit grass, so that her burden would be lighter.

"When these herbs are harvested, you will not sow any more seeds. I will give you a settling-in allowance to send you back to the world. ”

The two of them were taken aback by Ye Zi's sudden arrangement, and both asked in horror, "Master, did we do something wrong?" Don't drive us away, we'll fix it. ”

Ye Zi smiled and comforted the two: "You are mortals, unlike monks who have a long lifespan, one day, you will grow old, I don't want you to be lonely and helpless." Don't you want to find a sincere person, become your own child, and be happy when you are old? ”

The two were silent.

"I'll give you enough money to settle in, and only you can use it. Whether you live happily or not in the future is up to you. ”

The worry on the faces of the two slowly dissipated, and they were moved to tears, and they both knelt down and kowtowed.

"Thank you for your love, we will live a good life according to your instructions."

After instructing the two of them to do next, Ye Zi entered his bamboo building. I plan to devote myself to researching the refining of the Guiyuan Fire Zhi Pill.

According to the Dan Fang, the method of refining the Guiyuan Huozhi Dan is actually not difficult, and there are only a dozen kinds of materials. But each one is very precious and rare, if it weren't for the harvest in the Immortal Mansion this time, it is estimated that she would not be able to gather these materials.

Take the millennium star grass as an example. Star grass is a very common medicinal herb, but most of them are ten years old, and it is not easy to find a fifty-year-old one, let alone a thousand years old.

Because the star is the favorite food of the herbivore demon beasts, it can help the demon beasts increase the demon element and speed up the cultivation speed.

And she spent a million on figs. Needless to say, it is more valuable.

Thinking that the spirit stones of the flowers were all given by Qi Xuan, she was still a little awkward in her heart. But she had robbed more than one million spirit stones from him, and she would have to take out one million for a while. It's really difficult.

After dispelling the distracting thoughts in his heart, Ye Zi first sank into the dantian, condensed his mind and worked for a long week, and slowly exhaled a breath of turbidity.

Place the alchemy furnace and the materials prepared in advance in front of you one by one.

I watched the palms of my hands rise with orange flames as big as eggs. Ye Zi suddenly remembered. She has already built a foundation, and she can go to heaven and earth to integrate into her body.

This is true of many alchemists.

After the Dan furnace was evenly heated, the leaves calmly wrapped the star grass with spiritual power and threw it into the Dan furnace.

Seeing that the dark green blades of grass and grass roots slowly melted into steam under the high temperature, and finally turned into a small pool of liquid, she did not hurry to put in the second flavor of the herb, a hundred-year-old clover.

Then there are vermilion, blood vine root, chalcedony, stalactites, and purple flowers.

Then there were three drops of the ichor. This spiritual liquid was made of countless spirit stones in advance, and it was refined into vapor at high temperatures. Finally, it turns into a pure liquid, commonly known as spiritual liquid.

Ye Zi spent more than a thousand spirit stones refining these spiritual liquids.

Then there are the two most important steps. Put in the figs and finally the fire sesame fruit.

Looking at the dark green liquid gurgling in the Dan furnace, Ye Zi's nervous forehead was full of fine beads of sweat. Failure is not terrible, but if you want to find these materials again, it will undoubtedly be difficult to ascend to the sky, especially the fire zhiguo, except for the Baiyun Immortal Mansion, I have not heard of any other places at all.

After stabilizing his mind, the leaves calmly wrapped the figs and threw them into the medicinal solution, and with a "pop", after the figs sank into the medicinal liquid, they bubbled up twice, and there was no movement.

But soon, a powerful force suddenly filled the entire Dan furnace. Ye Zi had a hunch that if she couldn't control this power well, the Dan furnace would definitely explode!

But this force was so strong that she couldn't wait for her to guide it, and the Dan furnace trembled violently, and the triangular pillar collided with the ground with a "click" sound.

[Yaotian!] Help me! ]

Ye Zi knew very well that she must not let this furnace of pills be wasted, and calling Yao Tian was also an instinctive move, because she couldn't think of any other way.

Unexpectedly, Yao Tian didn't respond to her, but the black jade pendant on his chest revealed a strong purple light, enveloping the entire Dan furnace.

The Dan furnace was like an angry demon beast being appeased by its master, and it quickly quieted down obediently.

Ye Zi breathed a sigh of relief, and the voice of Yaotian lazily and sleepy sounded in his mind.

[Scared me to death, I thought you were going to die!] ]

Ye Zi wanted to roll her eyes, but at this moment, she couldn't help it. The figs in the Dan furnace had been melted, and the original dark green medicinal liquid had turned into half red and half purple, glowing with a strange luster.

[Why don't you refine a Guiyuan Dan, don't be so nervous, relax!] Yaotian's angry voice sounded in his head again.

The leaves still ignored it, preoccupied with the Dan furnace.

Finally, the half-red and half-purple liquid bubbled, and then boiled normally. This shows that the medicinal properties have been completely fused, and only need to be put in the fire mushroom fruit again!

Ye Zi was overjoyed, lightly wrapped half of the pitted fire sesame fruit with spiritual power, and was about to put it into the Dan furnace, when a loud shout of "stop" sounded in Leng Buding's brain, and her hand shook in shock, and the fire sesame fruit "snapped" and fell on the table.

"What are you doing?" Ye Zi screamed angrily.

[You stupid, you don't know how to do alchemy and don't ask me?] The Fire Zhi Fruit is originally made by condensing the essence of heaven and earth with fire spiritual energy, and it does not need to be refined at high temperatures, as long as it is fused with the medicinal liquid! ]

Ye Zi was stunned and hurriedly asked: [Then what now?] ]

[Control the flame to the size of a diced bean, and when the temperature of the liquid drops to 40 degrees, put the phoenix of the fire mushroom into it, and the residual temperature will slowly melt it.] ]

The leaves are stupid.

[Pea fire is also fire, as long as it burns all the time, the liquid will remain high and the temperature will remain the same, how can it be cold?] ]

Yao Tian was a little crazy: [Won't you use ice attribute spiritual power to help cool down?] You stupid pig! ]

Not to be outdone, Ye Zi fought back: [You are a stupid pig, I am a five-attribute spiritual root, how can I have any ice spiritual power?] ]

[uh......] Yaotian probably didn't expect this, and after a moment of embarrassment, he said: [That can only be risked.] You extinguish the flame and let the liquid cool naturally, but remember, when it is just 40 degrees, you should put in the flame of the bean cube in time, and put in the fire sesame fruit, and the score must be exactly the same, otherwise it will ......]

If Yao Tian didn't finish speaking, Ye Zi naturally knew what it was.

But what else could she do now?

It's just that she wishes she had a thermometer by her side now. While waiting for the cold liquid to cool down, she silently thought: In the future, I must ask someone to build a Dan furnace with a temperature gauge!

Ye Zi once read a scientific report. It is said that at a constant temperature, fingers can touch a metal object for about five seconds at 45 to 50 degrees Celsius. (To be continued.) )
