As soon as these words came out.

Gu Changfeng and Tian Jiuhan were both stunned on the spot, with confused expressions on their faces.

However, Master Lin felt as if he had been struck by lightning, and his face instantly turned pale.

"Master Lin, is what he said true?"

Gu Changfeng glanced at Master Lin suspiciously...

After a moment of silence, Tian Jiuhan also asked, "Master Lin, is the end of the Yangtze really the Yin?"

At this time, Xu Dong smiled and asked, "Master Lin, when you processed the red dragon grass, did you remove the roots?"

"No."

Master Lin raised his head and said with a fearful expression, "For some elixirs, in order to ensure the greatest effectiveness, the spiritual plant must be intact."

"I dealt with the red dragon grass just now in its entirety!"

Hearing this, Xu Dong stepped forward, patted Master Lin on the shoulder, and said, "It's a good thing I'm here today, otherwise your young master might die after taking the elixir."

Master Lin was immediately shocked.

Yes, Xu Dong was right.

Although red dragon grass is yang, its roots are yin and cold.

As soon as he found this recipe, he was so excited that he started refining it, but he completely ignored this point.

Fortunately, the elixir was not fed to the young master immediately, otherwise the consequences would have been disastrous.

"This...could it be that this kid was right?"

Gu Changfeng and Tian Jiuhan both had expressions of disbelief on their faces.

They all knew that this outer disciple had some tricks, otherwise it would be impossible to recognize the Heart-Eating Insect.

However, in their hearts, Master Lin, a world-famous alchemist, is the young master's savior.

As for Xu Fei, in front of Master Lin, the most he could do was come up with ideas, make moves or something like that.

But they never expected that Xu Fei would see Master Lin's mistake at a glance.

Is it possible that this little outer disciple is also proficient in alchemy?

Even more accomplished than Master Lin?

This idea was automatically rejected by the two of them as soon as it emerged.

>

Because Xu Fei's name seems to be unknown in the alchemy world, right? They have never heard of it at all.

"Then what should we do now?"

Master Lin was a little confused at the moment.

"Simple, just remove the roots of the red dragon grass." Xu Dong clasped his hands behind his back and replied.

"But the prescription I prepared was based on overall consideration. If the amount of red dragon grass is reduced, the dosage of medicinal materials will have to be adjusted a lot."

Master Lin's eyes widened and he said to himself, "This is undoubtedly a big project and requires precise calculations."

"Sect Master, please allow me another three or two days..."

Gu Changfeng subconsciously wanted to speak, but Xu Dong waved his hand impatiently, "I still want to practice! I don't have much time to waste, so please lend me the alchemy furnace."

After saying this, he walked to the alchemy furnace and took the elixir that Master Lin had refined.

Master Lin, on the other hand, did not stop him. Just like a student asking a teacher for advice, he watched attentively from the side.

"You made this elixir well, and its quality is also of the highest quality."

"The only flaw is that it contains a hint of Yin Qi."

"The solution is also very simple, which is to return the elixir to the furnace, refine it again, and add a cold-washing grass."

"Cold-washing grass has the effect of neutralizing the yin and cold air, and can remove all the cold air in the elixir."

"This way, everything will be safe."

As he spoke, Xu Dong took out a spiritual grass from his storage ring. It was completely white and looked like an ice sculpture.

It was clear that he was washing cold grass.

"You actually have cold-washing grass!"

When Master Lin saw this, he was shocked and exclaimed again and again.

Washing cold grass is a very rare spiritual grass, far more precious than red dragon grass.

It's so rare that you can't even buy it on the market.

Even with his status, it would be extremely difficult to obtain one.

But at this moment, Xu Dong took it out so easily, which was simply too arrogant.

Xu Dong waved his hand and said nonchalantly, "It's nothing!"

He plundered the four major saint clans in the Saint Demon King's Domain, and even he himself didn't know how much was hidden.

What does a mere cold-washing grass count?

After saying that, Xu Dong put all the elixir and cold-washing grass into the elixir furnace.

Then, he glanced at the room, lit a ray of light, and activated the ground fire switch.

When this move came out, Master Lin's eyes widened.

He could almost conclude that Xu Dong was an alchemist, and he was quite accomplished.

After all, he personally set up this earth fire formation, and non-experts cannot spy on it.

"boom!"

At this moment, the blazing earth fire started to burn.

As time passed by, a strong fragrance of elixir spread out.

Xu Dong sat on the futon, pinching the magic formula and controlling the heat at the same time. His movements were extremely familiar.

Master Lin's eyes widened and he watched attentively, not missing every detail.

When this scene came out, Gu Changfeng and Tian Jiuhan were stunned on the spot.

This, this, this...

It seems that Xu Fei is an alchemist and Master Lin is an alchemist...

It simply subverted their cognition.

"Done!"

About half a stick of incense had passed, and Xu Dong suddenly stood up, with a slight curve in the corner of his mouth, and then gently patted the alchemy furnace with his right hand.

"Whoosh!"

The furnace lid was blown away, and a crystal clear pill shot out.

The original elixir was slightly red in appearance, and besides the fragrance of the elixir,

, accompanied by a faint smell of blood.

But after Xu Dong refined it, the elixir turned into a golden color, as if it were cast from gold.

Moreover, the fragrance of elixir is overflowing!

The fragrance is like an invisible tide, spreading in all directions.

In an instant, it enveloped the entire room and continued to seep out.

“What an amazing scent!”

At this time, Master Lin was restrained.

From a certain perspective, the fragrance of the elixir represents the quality of the elixir.

The elixir Xu Dong refined has such a strong fragrance, which also shows that it is of extremely high quality, far better than the one he refined.

"alright."

"Sect Master, this is the elixir to save your son. Let him take it! It will take about one stick of incense to recover."

After saying that, Xu Dong threw the pill away casually.

Seeing this, Gu Changfeng hurried forward and took the elixir with both hands as if it were a treasure.

Then, he hesitated for a moment, as if he could not make up his mind, and turned to look at Master Lin.

Master Lin smiled bitterly, "This young master's alchemy skills are far better than mine. The sect master can trust him."

Hearing this, Gu Changfeng didn't hesitate at all. He quickly came to the bedside and stuffed the pill into his son's mouth.

Afterwards, everyone waited nervously.

When the elixir entered the young master's mouth, it turned into a pure power of the Yang.

The power of the Sun, like a storm, began to swim through his limbs and bones.

Of course, in addition to the power of the Sun, there is also a warm wood energy.

Because the young master at this moment has become a mortal.

No, his body is even more fragile than that of a mortal. His meridians can break at the touch of a touch, and he cannot support this majestic power of the Yang.
