Outside the room, Yuan Fei had already panicked into a dog.

Let him fight the enemy, even if the other party is a more powerful earth-level demon than him, he will not have any fear.

But alchemy......

Even with Xu Yi's advice, he felt unsure. Then, he saw Xu Yi open the door and wink at him. Yuan Fei forcibly calmed down, strode towards the door, and when he was at the door, he suddenly saw the Dan furnace inside.

He was slightly stunned, really let me do alchemy?

He opened his mouth towards Xu Yi and asked with his mouth, "What am I going to do?" ”

The corners of Xu Yi's mouth twitched, and he said with a smile: "Free to play." With that, he walked out and blocked the doorway.

Yuan Fei walked in with a blank face.

Free to play?

I'm free to play with your **......

Xing Chang and Mu Yongzhi glanced at each other, and they both walked over with solemn faces.

Although the two of them couldn't understand Yuan Fei's nonsense just now, they only felt that those words seemed to have some truth, but after thinking about it, it was impossible.

Since this is the case, it is better to take a look at this person's alchemy process with your own eyes, and maybe you will gain something.

As the saying goes, a mule is a horse, and you will know it when you pull it out and slip it on.

However, just as they wanted to enter the room, Xu Yi stretched out his hand to stop them.

Mu Yongzhi frowned slightly, and said, "Brother Yuanshi, what do you mean by this?"

Xu Yi said with a smile: "I am a rough man, I only know how to practice swords, and I don't know anything else." ”

In the room, Yuan Fei couldn't help but glance back.

You're a rough man, your whole family is a rough man. In addition to swordsmanship, what does Lao Tzu not know about qin, chess, calligraphy and painting?

Mu Yongzhi was stunned and said, "What's the matter?"

"I also have a question for both of you. If the two of you answer, then please come in, if you can't answer, hehe......" Xu Yi smiled and did not speak, but everyone understood the meaning of this sentence.

Mu Yongzhi sneered: "Brother Yuanshi, if you ask us how to practice swords, we really don't know. ”

Xu Yi shook his head again and again and said, "How can I deliberately embarrass the two of you, I am asking about the elixir." ”

Xing Chang waved his hand and said impatiently: "What questions, ask quickly." ”

He didn't want to talk to the rough man in front of him who could only play with the sword, with this time and energy, it was better to see how Xu Yi made alchemy.

Xu Yi said in a deep voice: "I want to know what is the difference between the Heaven-Rank Spirit Pill and the Heaven-Rank Spirit Pill that can heal the injuries of the Heaven-Rank powerhouses. ”

Both of them were stunned, they glanced at each other, and then understood it.

Xing Chang sighed lightly and said, "Brother Yuanshi, this question of yours was asked by Elder Daiguimen Gu. ”

Xu Yi said slowly: "So you know." ”

"Elder Gu has been asking for the Heavenly Rank Law Spirit Pill for more than ten years, and even if we are lonely and unheard, we have heard of one or two. Xing Chang shook his head and said, "Brother Yuan, you can't afford to get involved in this matter, so don't ask." ”

However, Xu Yi shook his head resolutely and said, "What if you insist on it." ”

Xing Chang frowned and looked towards Yuan Ding, but saw Yuan Ding looking up at the ceiling, as if there was some peerless secret book on it, attracting his attention, and turning a deaf ear to what happened here.

The two were helpless, knowing that if they didn't satisfy the man in front of them, they were afraid that they wouldn't be able to go in.

"Senior Brother Yuan, the so-called Heaven-Rank Spirit Pill is an ordinary Heaven-Rank Pill, and when the Heaven-Rank Alchemists are refining, they only need to project their own laws into it, and the refining can be completed. Xing Chang explained, "However, if there are Heaven Rank powerhouses who are seriously injured, then they must use a higher grade pill to heal their injuries. ”

Xu Yi's eyes were shining, these could be regarded as the secrets of Dan Dao, he listened attentively and refused to miss a word.

"The Heavenly Rank Alchemist uses the Law Projection Alchemy, which is an ordinary pill. However, if they use the power of the law origin to leave a magic rhyme on the elixir, then ......," Xing Chang said solemnly, "This elixir is called the Heaven Rank Law Pill, and it is a peerless treasure elixir that can make the Heaven Rank powerhouse heal. ”

"Heavenly Rank Law Elixir?" Xu Yi muttered a few words, as if he had an understanding in his heart, "Is this elixir difficult to refine?"

"Nonsense. Mu Yongzhi said impatiently, "That's the elixir that is going to consume the origin of the Heavenly Rank Alchemist's law, who dares to refine more?" Moreover, this kind of elixir is going to be punished by heaven, once the pill is completed, it will usher in a heavenly catastrophe." Whether the pill can cross the heavenly level or not, no one can help, and it can only rely on the pill itself. ”

Xu Yi was stunned for a moment, and said in surprise: "Doesn't that mean that if the pill can't survive the Heavenly Tribulation, even if it succeeds, it is equivalent to failure?"

"Yes, that's exactly the case, and under the Heavenly Tribulation, the Heavenly Rank Law Spirit Pill is destroyed and survived, so let's talk about it, whether this pill is precious or not. ”

Xu Yi finally understood why, with the power of the Skillful Weapon Sect, he still couldn't get a Heaven Rank Law Spirit Pill for Elder Gu for so many years.

Although this elixir is also a heaven-level elixir, it is the top elixir in the heaven-rank. Every time one is refined, it consumes the origin power of a heaven-level alchemist.

This is even greater than the consumption of Cheng Bo and others refining the Didi Pill, and it is definitely difficult to make up for it.

What's even more deceptive is that this elixir has to go through what kind of tribulation? And no one can help with this tribulation. The final result of the top-grade elixir refined by consuming the power of the origin is that nine are destroyed and one is saved, and if you are a heaven-level alchemist, you will never be able to open the furnace easily.

Mu Yongzhi said coldly: "We're done, can Brother Yuan Shi let him go?"

Xu Yi hurriedly stepped out of the way and said apologetically: "Two, it's Yuan Fei's fault, Yuan Fei apologizes to you." ”

In the room, the corners of Yuan Fei's mouth twitched, and he had already made a decision in his heart.

After the two of them change their identities, he must have a good discussion with his dear Senior Brother Xu.

Well, in order to make Senior Brother Xu have stronger self-preservation, he will never release water.

Xing Chang turned his gaze and immediately saw the Dan furnace, as well as Yuan Fei who was standing beside the Dan furnace with an expressionless face.

At this time, Yuan Fei's mental activity was extremely rich, but his face was unwavering, and he couldn't see a single color.

Of course, this is Mi Ji's brilliant makeup skills, but more importantly, it is Yuan Fei's cultivation of the sword heart, and he has already reached the realm where Mount Tai collapses in front of him and his face does not change.

Therefore, even if these two alchemists are also experienced people, they can't see the slightest flaw.

"What about the medicinal herbs?" said Yuan Fei coldly.

He knew that he was talking too much and doing more wrongs now, so he simply raised his posture and looked cold.

Fortunately, many alchemists seemed to be a different person when they were alchemizing, so the two of them did not suspect anything.

The two of them took out the space bag that they had prepared long ago, and each took out some medicinal herbs from the space bag.

Xu Yi could see clearly that the medicinal materials of these two people combined just enough to make up a furnace, and the two main medicines were even more one by one, which was very fair.

Yuan Fei glanced at it and said, "It's very well prepared." ”

Sisters Yuan Ding and Zhang Miaoyan both looked calm, but they secretly said in their hearts, ...... Can you really understand?
