Hua Lingyuan didn't think that they hadn't seen each other, with the experience and experience of these two people, even if she had personally used such an alchemy technique, she would definitely know more than a story.

The four people present knew that this move was just to lead to something, and alchemy was just an excuse to be set outside.

So Xin Bai continued to go against his old ways, and even spoke first again after a short pause.

"I already have a rough idea of what you want to refine, but I don't know why Senior Sister Hua would think of using this method to refine this elixir, using human blood into medicine actually doesn't have much effect, at most it plays the role of a medicine induction, but it will hurt the human body, in fact, it is not necessary. ”

As soon as Hua Lingyuan heard it, she understood that Xin Bai was asking what she was doing with human blood. Looking at Dugu Nanlin again, his expression was the same as Xin Bai, and his eyes flashed with doubt and disapproval.

Ah Xi's appearance was completely different from them, she sat behind Hua Lingyuan and secretly tugged the corner of Hua Lingyuan's clothes with her hand, looking very worried, as if she didn't want Hua Lingyuan to talk about it at all.

But Hua Lingyuan of course didn't pay attention to Ah Xi's actions, she sat very heroically on her two legs, her head slightly tilted to the side to look at the ink exposed in the corner, and one hand was still groping on it.

"Senior Brother Xin doesn't know, Ah Xi told me clearly, the cockroach harms people but only a few drops of human blood, and even the spirit mosquito likes to chase and bite people, which shows that human blood is not as useless as we understand. Maybe the human blood in other elixirs can only be used as a medicine guide, so that those who eat pills can have a comfort, but if you don't really add this thing to the insect repellent elixir, the flying cockroach can be fooled and pounce. ”

Her words made Xin Bai completely quiet, but Dugu Nanlin stared at it with his chest in his hands, and the light in his eyes was a little worrying, which made Ah Xi, who was also in the range of this gaze, even more afraid that there was a hole in the ground to get into.

Hua Lingyuan sensed Ah Xi's fear, turned her head to look at her, touched her hand and soothed her, and then glanced at Dugu Nanlin.

The two looked at each other in mid-air, and the content contained in it was a bit complicated.

Her words are not difficult to understand at all, but they can be scary.

At first, Xin Bai saw that little story, and thought that what Hua Lingyuan told him in such a complicated and obscure way was nothing more than discovering that someone in the medicine hall was using human blood for medicine. That's really not a big deal for him, and human blood does make people feel uncomfortable as a medicine in a sense.

However, on the contrary, it is precisely because human blood has such a meaning for people that there are stricter management measures in such matters as blood collection. Over the years, they have used human blood into medicine many times, but the origin of this blood is clean and innocent, and it must be taken voluntarily by the donor, and the blood must be taken on the premise that it will never harm health.

In addition, to be honest, even the blood used to refine a whole furnace of Dan does not need a lot, so for many years in the pharmaceutical alchemy world, how can this human blood be taboo. Some alchemists even don't even use human blood as medicine, but also add human blood to some special elixirs for blending, and the dosage will be slightly larger.

After such a long time of refining and development, human blood has never found anything dirty in this because of this relationship, so he doesn't feel that it is very serious in this matter, but he is willing to take care of it after seeing that although Hua Lingyuan has more thoughts, he still has some good thoughts.

Judging from what she had just said, it seemed that this was something extraordinary. Although her words are also talking about human blood in medicine, it sounds like she is implying that some kind of harmful thing she refers to with the flying cockroach is coming for this human blood.

So she wanted to say that there were people in this medicine hall and even the entire Xuanqing Sect who were specifically trying to get human blood, and the purpose was still ulterior, which was indeed very different from the nature of occasionally taking some blood into medicine.

"Listen to what you said is the Tao, but why has this spirit insect never been said, you don't want others to say that the wind is rain, if you want to change your mind, it's still too late. ”

Dugu Nanlin and Hua Lingyuan said something like this after eye contact, which sounded a little unbelievable. This is not to blame him, everyone has been talking about the topic of alchemy, and he is really not as proficient as Xin Bai in this regard, so the analysis is not so accurate.

is the same as Hua Lingyuan thought, he needs to use evidence to decide how to deal with affairs, if there is really something crazy for people's blood, how can it be that there is no leakage at all.

Hua Lingyuan can't help it in this regard, she originally came to go around such a big circle this time because of the situation, if you want to say that the witnesses are sitting in front of you, or are they really the two, you won't believe it.

But she can say a little more, maybe this Xin Bai, who appeared here unexpectedly, can be a good assist, and she is grateful to God that he is not the one surnamed Yi, she has a hunch that the turning point of this matter is this Senior Brother Xin.

"How does the senior brother know that no one has said anything about this spirit worm, probably because the existence of this spirit worm is too bizarre, but no one believes it after saying it a few times, the spirit worm is still very powerful and can't leave any traces, and over time, the victim will know that it is in vain, and then he will not want to mention it. But I'm just a coward, I can't always think of self-preservation until the end, anyway, other elixirs are not of much use to me, or this insect repellent can be used in case of accidents, I don't change. ”

She shook her head like a rattle at Dugu Nanlin, and her stubborn appearance would definitely make people who don't know why she didn't know what to do, but Xin Bai and Dugu Nanlin wouldn't.

"Then can this handyman disciple behind you describe to you what the symptoms will be after being injured by this flying cockroach when chatting with you, the more I know, the better you can refine this elixir. ”

Xin Bai answered again.

Hua Lingyuan was finally a little excited when she heard this, and said in her heart that this professional matter really has to talk to professionals, Xin Bai just believed what she said, okay, okay, as long as she takes two more steps forward, this goal should be achieved today.

So she hastened to answer.

"Oh, Senior Brother Xin doesn't know, didn't I say it, the person who was given the disaster by this flying cockroach has been untrusted for many years, so he has been silent about this matter, and if you want to know the situation in detail, where can you talk about it for a day. Senior brother can probably see that Ah Xi is more introverted, and he probably said everything on the day he could tell me, and if he can't say it, he has to think about it slowly. ”
