"In this case, you have already prepared. I am afraid that what awaits us next will be a tough battle."
After speaking, Zhishen shook his head, turned around and returned to his room.
Zhang Yifeng, with a solemn look on his face, turned around and returned to the alchemy room to continue refining the alchemy.
After a night of tireless refining, Zhang Yifeng put all the refined elixirs into the storage ring, and then swallowed one elixir.
It seems that Muxue has already tested the efficacy of the elixir. In this case, Zhang Yifeng should go to the meeting place to have a look.
However, just as Zhang Yifeng walked out of the alchemy room, a woman in white with an indifferent expression appeared outside the door of the alchemy room.
Feeling the vitality of the visitor, Zhang Yifeng knew that Muxue did not send a spirit puppet this time.
"Haha, isn't this Miss Muxue? Why didn't you send a spirit puppet this time?"
Zhang Yifeng faced Muxue himself and chuckled.
"You! Forget it, your elixir is indeed effective, but the effect is so poor that it can be described as tasteless!"
Mu Xue was teased by Zhang Yifeng, and her beautiful eyebrows furrowed slightly, with a slight blush of annoyance on her face.
"Ahem, Miss Muxue, have you forgotten that the prescription you gave me is for castration. I can improve the prescription in half a day, which is pretty good, right?"
Zhang Yifeng shrugged helplessly, if you just gave me the complete prescription, there would be no need for it like this.
"You, hum, okay, I admit that you do have some talent in alchemy. In this case, I can give you this prescription. But in order to prevent you from changing your mind later, we must swear by the inner demon!"
Zhang Yifeng raised his brows when he heard this. Taking an oath by one's inner demon can be said to be a very strict oath in Lingyue Continent. If you don't do it right, your future may be ruined.
However, Zhang Yifeng originally didn't want to do anything like burning bridges across rivers, so he immediately nodded and agreed to Muxue's request.
Then the two of them each swore an oath with a drop of their heart's blood. The next second, a black energy fell from the sky into their blood, and the oath of the inner demon was completed.
The two people's oath is also very simple, that is, Mu Xue must give Zhang Yifeng a complete prescription without any private tampering.
As for Zhang Yifeng, after successfully improving the prescription, he must hand over a complete copy of the improved prescription to Muxue. If there is any violation, he will suffer the pain of the devil eating his heart.
After completing the oath, Muxue was very generous and directly handed the original prescription that she carried with her to Zhang Yifeng.
"This is the original recipe. No matter whether you can refine it or not, this recipe must not be damaged, otherwise I will make you walk away without being able to take it!"
With a cold snort, Muxue turned and left, while Zhang Yifeng looked at the original prescription in his hand, dumbfounded.
Judging from the prescription, what Muxue gave before was really a castrated version of castration, and even some of the medicinal ingredients were not from the original recipe at all.
Zhang Yifeng was able to successfully improve himself, but he doesn't know whether to say he is lucky or talented.
He shook his head helplessly, and after reading the prescription carefully and completely, Zhang Yifeng had already memorized all the medicinal materials required for the prescription.
Then, Zhang Yifeng silently began to deduce it in his mind. However, no matter how Zhang Yifeng deduce it, he always felt that it was a little bit wrong.
The shortcoming was not Zhang Yifeng's insufficient deduction, but the problem with the prescription given by Mu Xue.
However, according to the oath of the inner demon, Muxue would not hide any details secretly, that is, there is something wrong with the prescription itself.
Zhang Yifeng is proficient in the art of alchemy, and he has a clear mind about the possible manipulations that can be done on the prescription, so he immediately begins to experiment.
Sure enough, after boiling, roasting, and various testing methods, the last medicinal ingredient on the prescription appeared in front of Zhang Yifeng.
It seemed that Muxue's master had hidden it well enough. Even his apprentices did not tell him that there was such a detail in the prescription.
Of course, this was just Zhang Yifeng overthinking. In fact, it was just Muxue's master who died of serious injuries before he could tell Muxue the secret of the prescription.
Therefore, over the years, the medicinal liquid that Muxue refined has always lacked such a medicinal ingredient, which has resulted in the medicinal liquid increasing its effect on the body less and less.
He put the prescription away helplessly. At this time, the prescription had been tortured by Zhang Yifeng and had become missing corners. It looked more like a prescription passed down from the ancestors.
After the prescription was completely completed, Zhang Yifeng immediately performed the deduction again in the sea of consciousness. This time it was much faster, and many medicinal materials could match the prescription.
After a period of exploration, Zhang Yifeng finally had a general direction. Then he went to the alchemy room to ask for the necessary materials, and then started the formal improvement.
Finally, after a day and night of continuous attempts, Zhang Yifeng developed a brand new recipe.
Feeling the warm elixir in his hand, Zhang Yifeng's eyes flashed with light. The elixir refined from this improved elixir was at least ten times more effective than before.
After all, the medicinal solution originally used by Muxue always lacked some medicinal ingredients. This also resulted in the quality of the medicinal solution in Muxue's hands not being very good, so its effectiveness was limited.
A look of perseverance flashed across Zhang Yifeng's eyes, and the next second Zhang Yifeng swallowed the pill in his hand.
The elixir melted immediately in his mouth, and the pure liquid rushed toward Zhang Yifeng's limbs and acupuncture points. Suddenly, a huge tearing feeling came from his body.
However, Zhang Yifeng is not a fool, and his resistance to pain is also very strong. Even if there is such heartbreaking pain in his body, Zhang Yifeng can still bear it with a calm expression.
The violent liquid medicine continued to wash away Zhang Yifeng's body, and Zhang Yifeng's War Immortal Body was also washed by the liquid medicine at this time and began to slowly advance.
Zhang Yifeng was overjoyed when he saw this, and immediately grabbed another pill and swallowed it. The training progress of the Fighting Immortal Body immediately improved a lot.
Finally, when Zhang Yifeng had taken only three pills, Zhang Yifeng's War Immortal Body broke through again.
Powerful golden light exploded from Zhang Yifeng's body, and powerful aura continued to overflow from Zhang Yifeng's body.
Fortunately, Zhang Yifeng quickly controlled the abnormality in his body, so he did not attract the attention of any powerful being.
However, the War Immortal Body has taken another step forward, which is definitely a good thing for Zhang Yifeng. Originally, he just wanted to use this elixir to improve his physical strength.
As a result, I didn't expect that this elixir could actually improve the progress of the Fighting Immortal Body. It seems that this elixir will be refined more in the future to assist the training of the Fighting Immortal Body.
