Once he made up his mind, Ah Zi didn't delay for a moment and started to act.

Since her blood has such a miraculous effect, so that the Dongyuan royal family does not hesitate to risk sacrificing their own credit to hide it from the people, trying to take the demon blood for themselves, then the most direct way to repay Liu Siqi and Hui Niang is to donate their own blood to them.

But how do you give it?

Is it just a cup and a tray to send out?

As soon as the thought came out, Ah Zi immediately shook his head, what is the difference between that and the barbarians of the primitive tribe.

What's more, she hopes that her blood can be put to better use. But now Liu Siqi and Hui Niang don't have any serious illnesses that need urgent treatment, and drinking her healing blood is nothing more than using it as a tonic to replenish their bodies.

So how about storing the blood so that they can take it out when they need it, maybe it could really save their lives?

Thinking of this, the corners of Ah Zi's mouth unconsciously hooked: A dignified doctor immortal, one day he has to rely on his own blood to save his life, such a moment just thinking about it already feels a little fluttering in his heart.

But what is the most convenient and effective way to store it......

Ah Zi couldn't help frowning again, the only knowledge she had now in medicine was the herbal medicine collection and a few entry-level medical books that she copied a few days ago, and now she had to find a way to store blood by herself, it was really difficult for her.

But no matter how hard it is, try it.

She began to rummage through the study for all kinds of books, and finally simply went into the backyard stack to search for them, and even missed lunch time.

Hui Niang searched for her in the main courtyard for a long time, and finally saw her come out of the library with a stunned face, hurriedly pulled her to sit down, and asked her what happened with concern.

"I want to learn how to store medicines." Ah Zi said vaguely.

Hui Niang thought about it and asked her what kind of medicine she wanted to store, maybe she could help.

Ah Zi just woke up from a dream, even if she didn't want Hui Niang and Liu Siqi to know in advance that they were going to donate their blood, it didn't mean that they couldn't ask them how to store blood.

At this time, Ah Zi became interested, looked at Hui Niang with expectant eyes, and said: "It's a kind of juice, I want to find a way to store it for a long time, and I can use it whenever I want." ”

When Hui Niang heard her say this, she also showed a look of embarrassment for a while, but she immediately smiled and wrote on the paper: "Go and ask Mr." ”

When the sun set in the evening, Liu Siqi came back from outside, and before he had time to change his clothes and wash, he was blocked by Hui Niang and Ah Zi and asked.

"Oh? Storing potions? What kind of concoction? ”

Liu Siqi asked with curiosity on his face, but Ah Zi lowered his eyes and whispered with a little weakness: "It's just ordinary juice......"

Asked her to answer vaguely, Liu Siqi said with a straight face: "I ask this because different juices have different ways to store and dispose of them, such as some medicinal juices only need to be boiled, and some may destroy the medicinal effect with the same method." If you don't tell me the specific ingredient source of the potion you're going to deal with, how can I help you? ”

Ah Zi knew that what Liu Siqi said made sense, so she could only whisper back: "Yes...... is the blood of an animal......"

When Liu Siqi heard this, he frowned slightly, staring at Ah Zi, his eyes full of suspicion.

Ah Zi was even more weak-hearted, shrunk his neck, and didn't dare to come out.

Fortunately, Liu Siqi didn't think much about it in the end, but soothed his expression and said softly: "It's best to use the fumigation method I have newly researched to refine it, and then wrap it in agar and sugar coating to make pills." I'll give you the method I've recorded later, and you can just find it. ”

Ah Zi's eyes were full of joy that she couldn't hide after hearing this, thanked her again and again, and then went happily like a little bird.

After the meal, Liu Siqi gave Ah Zi the booklet that recorded the method of fumigation, and then called Hui Niang to ask him alone.

"Did she tell you exactly what kind of medicine she was going to take?" Liu Siqi asked calmly.

Hui Niang shook her head.

Liu Siqi responded, and said: "This little girl is probably going to use her own blood to make medicine." ”

Hui Niang's eyes widened when she heard this, and she looked incredulous.

Liu Siqi shook his head with a smile and said, "I told her about the arrangements I planned to entrust her to Lao He two days ago, and I revealed to her the effect of demon blood. I'm afraid that she is worried about what variables she will have when she leaves the Medicine Immortal Valley, and she wants to use her own blood to make a pill and take it out, so that she can cure and save people when she needs it, and she will not be discovered as a witch. ”

After finishing speaking, thinking of Ah Zi's happy look after taking the method of medicine, he felt that these were nothing, so he breathed a long sigh of relief and said, "Let her go." After all, we have lived together for a while, and we can help her as much as possible before leaving, and we can only rely on her to go on the road in the future. ”

Hui Niang nodded when she heard this, thinking that Ah Zi was going to leave the Medicine Immortal Valley like this, she was reluctant in her heart, and for a while, her eyes were covered with a layer of mist.

"You go to the cabin and see how she is doing," Liu Siqi commanded again, "This fumigation method requires some skill, but I am afraid that it will be difficult for her to succeed the first time like this, if you see any difficulties for her, just come and tell me, I can help her solve it in time." ”

Hui Niang nodded, bowed, and retreated.

After that, Ah Zi stumbled in the cabin, and although Liu Siqi secretly helped, it took three days to finally make four lilac pills.

Looking at the pills quietly placed in the medicine bottle, Ah Zi was indescribably happy.

At this time, Hui Niang walked in, and brought the small notebook with handwriting to Ah Zi: "Mr. asked you to go to the hall, saying that Mr. He has already come to the hall, and he will take you over." ”

Seeing this, Ah Zi's joy just now was swept away, and all that was left was reluctance.

Hui Niang also sighed sadly and stepped forward to comfort her.

Ah Zi looked at Hui Niang, suddenly jumped up as if she remembered something, took out a pill from the medicine bottle that was slightly larger than the other three and had a different shape, handed it to Hui Niang, and said, "This is what I made for you on purpose." ”

Hui Niang took the pill and looked at Ah Zi puzzled.

Ah Zi smiled innocently and urged, "Eat it quickly." When I made this one, I made it with a sugar coating and a layer of medicinal juice. When you put it in your mouth, each layer of icing will release a layer of liquid that will pass through your throat and should heal the wound in your throat. ”

Hui Niang held the pill and was a little embarrassed, but seeing Ah Zi's eyes full of anticipation, it was difficult to refuse, so she had to be respectful and obedient, and put the pill in her mouth.
