Sun Dafu's alchemy furnace looks of good quality.

Although Lu Yi couldn't understand what material was cast from the alchemy furnace, judging from its complex patterns and mysterious formations, this alchemy furnace is of absolutely great value.

Sun Dafu is not tall, only to Lu Yi's shoulder position.

And this alchemy furnace was almost as tall as Sun Dafu. Seeing him holding the alchemy furnace to control the fire was a bit funny.

"Don't look at me, look at the alchemy furnace!" Sun Dafu said with a blank look at Lu Yi.

It is definitely a rare thing to be able to see the alchemist refining spiritual pills with his own eyes.

Through the knowledge in the book, Lu Yi also knows the taboos of some alchemists.

Every alchemist will have his own unique refining technique when refining spiritual pills.

For example, some alchemists with higher grades regard this refining technique as a unique secret technique, which is impossible to spread.

Moreover, the pill recipe is precious, so every pill master will never let others watch it when he refines the spiritual pill.

Especially if you are both alchemists, it is even more impossible.

"Look at it, I... I will open your eyes!"

Sun Dafu hummed proudly, then began to control the purple flame and sent it into the alchemy furnace.

"The first step is called preheating. The casting elixir furnace has a special material and is extremely thermally insulated. It is necessary to preheat with flame in advance, so that the medicinal materials can be condensed into the medicine liquid as soon as possible after entering the elixir furnace."

While controlling the flames, Sun Dafu gave a detailed explanation.

A few minutes later, Sun Dafu said, "Look carefully, I'm going to add medicinal materials!"

Brush!

Sun Dafu sent some medicinal materials from the space ring into the alchemy furnace one after another.

Lu Yi is familiar with these medicinal materials, not very rare, but the age is not low.

"What kind of spiritual pill is this you refined?" Lu Yi said curiously.

"Nonsense, of course it's a first-grade spiritual pill, you idiot." Sun Dafu said contemptuously.

"I'm asking you what the effect of this spiritual pill is!" Lu Yi asked again.

Sun Dafu replied: "Although I am a first-grade alchemist, I can't refine several kinds of elixirs, because even the first-grade alchemist is difficult to refine. Even the second-grade alchemist is less than 70% sure..."

Then Sun Dafu briefly told Lu Yi some of it, which was indeed much more useful than in books.

Generally speaking, if you can successfully refine the first-grade spiritual pill, you can become a first-grade alchemist.

However, each alchemist has different levels, and the same level of spiritual pills is also different, and the difficulty of refining is also different.

For example, it is extremely difficult to refine the elixir that enhances cultivation and improves mental power.

Some auxiliary spiritual pills that can eliminate poison, fire, and disguise are much easier.

"I just became a first-class alchemist. My pill rate was only 40%, but I was more than enough to give you guidance!" Sun Dafu remained arrogant.

"When the elixir rate reaches 100%, you can become a second-grade alchemist?" Lu Yi asked.

"No, it's enough to reach 80%, because although many spiritual pills are first-grade, the difficulty of refining is greater than that of some second-grade spiritual pills." Sun Dafu explained.

Only then did Lu Yi understand.

The grade of the alchemist is divided according to the strength of refining the spiritual pill.

The grade of the elixir is divided according to the efficacy of the elixir and has little to do with the difficulty of refining.

Among them, the promotion of alchemist level is also closely related to the level of cultivation.

For example, an experienced alchemist who cannot keep up with his cultivation level when he is qualified in fire control, mental power, and elixir-making rate. Such a person still cannot improve his alchemist level.

Because when refining the spiritual pill, the consumption of immortal energy is also extremely terrifying.

"Note, I need to condense the pill!" Sun Dafu suddenly became nervous.

At this time, Lu Yi could feel that Sun Dafu's aura was rapidly weakening.

This is because a large amount of immortal energy in the body passes away.

I saw that his forehead was constantly oozing, and his face was bloodless.

"Closed for me!" Sun Dafu shouted in a low voice.

The flames in the alchemy furnace suddenly became violent, and the refined medicine began to condense together.

Lu Yi originally wanted to use his mental power to see what the process of the medicine liquid condensed pill was like.

But I found that an extremely terrifying force was brewing in the alchemy furnace.

"not good!"

Lu Yi's face changed, and he pulled Sun Dafu away and kicked the alchemy furnace into the cultivation room.

"Ah—" Sun Dafu exclaimed.

Immediately afterwards, a roar rang in the practice room.

Fortunately, the training room has undergone special treatment and is reinforced with defensive formations, so there is no terrible consequence.

Otherwise, the explosion just now would not only destroy the entire inn, but even Lu Yi would be in danger of his life.

"What are you doing?" Lu Yi picked up Sun Dafu and scolded angrily.

Sun Dafu originally wanted to explain something, but his expression suddenly became so proud. He didn't say a word, and he even spit out a mouthful of blood.

Seeing that the situation was not good, Lu Yi quickly divided the dragon essence into one and input it into Sun Dafu's body.

Then he took out the golden needle and sealed Sun Dafu's large acupoints, then helped him to vent the disordered meridians in his body, allowing him to gradually calm down the surging blood.

"Huh? Your method is so powerful. What kind of wonderful thing is this?" Sun Dafu looked at the golden needle on his body and showed a curious look.

A few minutes later, Lu Yi took back the golden needle.

"I'm fine!" Sun Dafu cheered and jumped a few times on the spot.

"You fake alchemist, you can actually laugh?" Lu Yi was completely helpless.

I really don’t know if Sun Dafu is simple in his heart or is born stupid.

"Who is a fake alchemist? I am a serious first-class alchemist, okay? I am qualified to be certified!"

Sun Dafu was very dissatisfied and pulled the fire robe in front of Lu Yi, took out a small sign, and swayed it in front of Lu Yi.

"A alchemist who almost blows himself up? Do you think it's a bit credible." Lu Yi sneered.

"I said it was an accident just now, do you believe it? I don't want it like this either..."

Sun Dafu knew that he was in the wrong, so he didn't dare to refute loudly. He silently went to the training room to extinguish the fire, sorted out the residue of the medicinal materials, and took the alchemy furnace back into the ring.

"It's true that it's not possible. I always make mistakes in the last step." Sun Dafu said a little depressed.

In fact, from the skillful method, Lu Yi was sure that Sun Dafu was indeed an alchemist.

As for why refining the spiritual pill failed, Lu Yi is not sure yet.

"I'll ask you, is the spiritual pill you just refined very difficult?"

"On average!"

"Have you ever refined it before?"

"Of course! When I became a first-grade alchemist, I refine it through it!" Sun Dafu said seriously and seriously.

Seeing his appearance, Lu Yi knew that Sun Dafu did not lie to him.

Although Sun Dafu likes to joke, he is not a scheming person who likes to lie.

"It seems that I'm right." Lu Yi murmured in a low voice.

"What?"

"What caused you to fail to refine your alchemy just now should be a restriction in your body. At the last moment, the immortal energy was hindered, making you unable to exert all your strength."

When Lu Yi finished saying this, a murderous intent suddenly burst out in Sun Dafu's eyes.

Immediately afterwards, a phantom sword light flashed in his hand and quickly stabbed Lu Yi's eyebrows.
