Nie Fei's eyes swept away, and sure enough, he saw that everyone was queuing. Therefore, Nie Fei walked to the end of the line, and like everyone else, waited in line to buy the double-edged grass.

Finally, Nie Fei finally arrived. The guy asked Nie Fei, "What herbs do you want?"

"Two double-edged grasses. ”

With a move behind the man, a medicine cabinet opened, and two double-edged grasses flew into his hands. The guy slapped the two double-edged grasses on the counter, "A total of 100 spirit stones, bring them." ”

Nie Fei had long known the price of this double-edged grass, and a hundred spirit stones was the standard price. But when Nie Fei buys things, he has always had to bargain, so he said, "Senior brother, how about two fifty spirit stones?" Nie Fei's idea was to lower the price first, and then the two of them would move closer to the middle together, as long as the transaction was below eighty spirit stones.

The guy's eyebrows furrowed, "Do you want to buy it?" Baicaotang is also a place for you to bargain? I know that Elder Lin has always been short of money, and I pity him too, but I can't give it away for nothing. You have to come back when you have enough spirit stones, and you can't miss a spirit stone. ”

How could Nie Fei miss so many spirit stones? He saw that guy looked down on Lin Qiao again and again, and his heart was not very comfortable. After sneering, he took out a hundred spirit stones from the storage bag, slapped them on the counter with a bang, grabbed two double-edged grasses and turned away.

The guy looked at Nie Fei's back and was a little stunned. Lin Qiao was a frequent visitor here, he clearly remembered that the last time Lin Qiao came, he had spent all the spirit stones, and it was only two days of hard work, where did he get a hundred spirit stones?

He was a little puzzled, and he was stunned. As for saying that these spirit stones might be Nie Fei's own, he hadn't even thought about it.

......

Nie Fei returned to his residence, and as soon as he walked in the door, he saw Master Lin Qiao walking around the courtyard with his head down, as if he had something on his mind.

Nie Fei was slightly surprised, and hurriedly stepped forward and asked, "Master, why don't you come to the house?"

Lin Qiao stopped and smiled slightly: "Nie Fei, are you back?" Nie Fei saw that Lin Qiao's smile was slightly strange, and he couldn't help but be surprised again. Lin Qiao continued: "It's good to come back. Nie Fei, I have something I want to talk to you about......"

Nie Fei waited for Lin Qiao to continue, but Lin Qiao didn't say anything. Nie Fei clearly saw that Lin Qiao's face showed a rather embarrassed look, as if he didn't know how to speak.

Nie Fei smiled and said, "Master, what do you want to say to your disciple?"

After a while, Lin Qiao's expression became firm, and he said, "Nie Fei, that's the case, Master, the double-edged grass that I need to refine the detoxification powder is gone now, so I have to buy some." But...... But Master, I've been a little short of money lately, can you see if you can ...... Can you lend Master a hundred spirit stones?" Lin Qiao's face turned red when he said this, which showed how embarrassed he was.

Nie Fei sighed slightly in his heart, "It's really not easy to be a master in this role. Of course, he didn't show it on his face, and said, "So that's the case, what else should I do." There is a good saying, if the master has something, the disciple will obey it. The disciple then presented the spirit stone. Saying that, Nie Fei took out a hundred spirit stones from the storage bag and handed them to Lin Qiao.

Lin Qiaoden was in ecstasy, took the spirit stone with both hands, and said excitedly: "Nie Fei, you are really a good disciple of Master. Don't worry, when the master's elixir is refined and the elixir is sold, these spirit stones will be returned to you. At that time, Master will give you some more, which will be counted as interest. In short, you will never be disadvantaged. ”

Nie Fei thought to himself: That is to say, these spirit stones, don't expect to come back.

Lin Qiao threw the spirit stone into the storage bag and walked out of the courtyard gate happily. Nie Fei didn't ask him what he was going to do, did he still need to ask? He must have had a spirit stone and went to buy double-edged grass.

Nie Fei looked at the back of this master and shook his head, "This master, I don't know how to mix it, it's too miserable, even a hundred spirit stones have to be borrowed from the disciple." ”

......

Back in his room, Nie Fei began to prepare to refine the detoxification powder according to his own method.

In fact, if you want to talk about preparation, everything is complete now, the double-edged grass is there, and the fire feather beast Neidan also has it. The first operation is that the herb and the inner pill are each ground and dissolved in the solution.

This kind of operation, for Nie Fei, is like being familiar with a car, he can do it with his eyes closed. In a short time, he had prepared the two solutions. The solution of the double-edged grass showed a pink color, which was similar to the color of the Fire Feather Pill solution.

Next, it was the most critical step, Nie Fei wanted to mix the two solutions to see if the solution of the Fire Feather Pill could extract the fire poison from the double-edged grass.

Every time there was such a critical moment, Nie Fei's heart was always extremely calm, which was the opposite of Lin Qiao. When Lin Qiao was refining the detoxification powder, he was so nervous that his hands kept trembling. This situation, in Nie Fei's case, will never occur.

Nie Fei lifted the jade cup containing the Fire Feather Pill solution in his left hand and slowly added it to the double-edged grass solution. At the same time, a thin jade stick in the right hand was constantly stirred in the jade cup of the double-edged grass.

As soon as the solution of the Fire Feather Pill was injected into the solution of the double-edged grass, it immediately reacted. This reaction is mainly reflected in the color change. As soon as the two solutions were mixed together, the color suddenly turned into a red like blood, and as Nie Fei stirred, the red swirled like a whirlpool, looking like a ball of blood stirring.

As the Fire Feather Pill solution continues to be injected, the color becomes darker and darker. It wasn't until the color stopped changing completely that Nie Fei stopped adding to it, took away the jade stick used for stirring, and let the mixed solution slowly come to a standstill.

After a few moments, the solution begins to stratify. The upper layer is a dark red liquid, while the lower layer is a clear liquid with a slight green tinge.

Seeing this, Nie Fei was so excited that he couldn't help but clap his hands and jump. When this situation occurs, it means that the real yàn has become, and the dark red liquid in the upper layer is the extracted fire poison, and the clear liquid in the lower layer is undoubtedly the active ingredient of the double-edged grass.

Then, Nie Fei used a funnel to take the liquid out of the jade cup. Actually, it's not difficult, the preparation of the funnel, as mentioned above, is to drill a small hole at the bottom of a jade bowl, and then pour the solution into the jade bowl, and when it is fully still, open the small hole, and the clear liquid will naturally flow out.

Nie Fei looked at the clear liquid, this is the effective ingredient of detoxification, look at how pure it is.

So far, Nie Fei can loudly announce to the world that the detoxification powder has been successfully refined by him, and he is also a first-level alchemist. "If you want to become an alchemist, who said that you have to cultivate wood aura, that's just the shallow understanding of the ignorant. I don't cultivate Wood Spiritual Qi, don't I still refine the detoxification dispersion?" Nie Fei thought proudly in his heart.
