And Mu Chen's purpose is to use the poison induction pill to guide the toxins in the little medicine fairy's body, and then excrete all of them from the body.

In addition, Mu Chen's leech clan blood exchange technique brought from Jade Spirit in the fox demon little red lady plane changed all the blood in the little medicine fairy's body, because the blood of the little medicine fairy itself is highly poisonous.

If he didn't do this, then the little medicine fairy's doom poison body would not be able to completely change, but in this case, it would be too harmful to the little medicine fairy.

If she didn't have enough spiritual power to repair her body, she would definitely not be able to persevere, after all, blood exchange is not a simple blood exchange.

The reason why Jin Renfeng could exchange Dongfang Huaizhu's father's blood for himself was precisely because his own strength was not weak.

If you really want to say it, the Jin Renfeng at that time was already at the level of the early stage of the Jindan Realm, and if you convert it, in the world on this side of the Dou Breaking Firmament, at least they are all Dou Huang level powerhouses.

And what about the little medicine fairy? She's just a little girl who fights, and if you really want to compare her with ordinary people, she's a little stronger than ordinary people at most.

In the low-level martial arts plane, he can only be regarded as a third-rate master at most, and even the second-rate is not ranked.

Her body is not much stronger than ordinary people, such a fragile little girl, if it were not for Mu Chen's help, just pulling out the blood in her body would be enough to kill her.

As for whose blood he wanted to exchange for her, Mu Chen was naturally ready for a long time, and this kind of thing of exchanging his blood for her, unless he had a bad brain, he wouldn't do it.

After all, the blood in his body is not just a bloodline, but a collection of black dragon bloodlines and the ability of the sun's light, and the black armor that can maximize the potential is his biggest hole card, how could he do such a thing?

Moreover, the bloodline he wants to exchange for the little medicine immortal is the spiritual blood of the Dongfang family, and as for whose blood it is, it is naturally Dongfang Yueyue.

After all, the force value of the fox demon little red lady plane is not low at all, there are many people who have the ability to destroy the world, but the lifespan of the human race is really pitiful.

Even if Dongfang Yue finally broke through to the Jindan Realm, it had no effect, and in the end he still died of old age, and before Dongfang Yue died of old age, he deliberately gave all his spiritual blood to Mu Chen.

In the early days, the blood was placed in the storage space by Mu Chen, but when the system recovered, his four-dimensional space bag could be used, and finally Mu Chen put all these things in the four-dimensional space bag.

After all, compared to the limited storage space, the system's four-dimensional space bag is infinitely large, and it is also more secure.

Moreover, the four-dimensional space bag is his personal thing, and it is more than one level more convenient than the storage bag.

When Mu Chen walked into the room, the little doctor fairy was lying on the table boringly, supporting his little head with one hand, as if he was thinking about something, he was very engrossed, and he didn't even notice that Mu Chen walked in.

"Little Doctor Fairy, what are you thinking? Thinking so intrigued. Mu Chen looked at the little medicine fairy and asked jokingly.

"Huh? There you are? As soon as Mu Chen spoke, he immediately pulled the little doctor fairy back from his fantasy, and when he saw Mu Chen walking in, the little doctor fairy couldn't help but blush, not knowing what he was thinking.

Of course, Mu Chen also noticed the change in the face of the little medicine fairy, and there was a slight hint of panic on the other party's face, and such a look would only appear on the face of someone who had done something bad.

It can be seen from here that what Xiao Yixian was thinking about just now must have something to do with Mu Chen, of course, Mu Chen didn't bother to ask about it.

"Okay, don't think about those useless things, since you have entered my door, I should have taught you things directly, but now the main purpose is to solve your special physique, but before that, I still want to ask you, would you like to learn alchemy?" Mu Chen asked the little doctor fairy directly.

Mu Chen didn't plan to teach Xiao Yan alchemy, after all, Mu Chen didn't plan to let Xiao Yan become an alchemist, not for anything else, Mu Chen came to this plane, but he planned to absorb the alien fire and let his World-Destroying Demon Yan evolve, he naturally wouldn't give this opportunity to others.

Even if it was his own disciple, he would not give up this opportunity easily.

Moreover, with the Yang Yan recipe taught by Mu Chen, Xiao Yan's future achievements will definitely be stronger than in the original book, so there is no need for him to learn any alchemy at all, after all, the pill is only an auxiliary, and the strength is real.

As long as his strength is strong, is he still afraid that there will be no pills in the future?

As for why he wanted to teach Xiao Yixian alchemy, what Mu Chen wanted to exchange for her was Dongfang Yue's blood after that, and after the blood exchange, Xiao Yixian naturally had pure Yangyan.

Although the power of pure Yang Yan is a little worse than that of the World-Destroying Demon Yan, it is more than enough to use it for alchemy, which is why Mu Chen asked the little doctor if he wanted to learn alchemy.

"Alchemy? Learn, of course I have to learn, if you learn alchemy, you can become a great alchemist, why not learn? After hearing Mu Chen's words, the little doctor immediately replied.

You must know that there are many people in the Douqi Continent who want to learn alchemy, but they don't have this opportunity, and at this moment, the opportunity is in front of their eyes, she is not a fool, how can she not want it?

"Okay, I'll put some of the foundations of alchemy into your body now, and I'll be alchemy in the house later, and you'll be watching from the side, if there's anything you don't understand, just ask me questions when I'm done alchemy." Mu Chen said.

After saying that, he walked directly to the little medicine fairy without saying anything, and then lightly touched her forehead.

Then Mu Chen directly launched the Soul Awakening Technique, which put some of the foundations of alchemy into her mind, and as for those massive memories, Mu Chen really didn't dare to transmit them all into her mind at once.

After all, no matter how good the little medicine fairy is, he is just an ordinary person, and the bearing capacity of the brain is not strong, otherwise, Mu Chen only needs to put all the memories of Yao Lao into her mind, and her alchemy ability can immediately catch up with Mu Chen.

But he can only think about this kind of thing, you must know that Yao Lao's memory is very huge, and he can digest it, which does not mean that others can also digest it.

"Got it?" After the little medicine fairy had almost completely digested those memories, Mu Chen spoke.

"Uh.... I kind of know some of the basic steps. The little medicine fairy replied.
