Gu Qingfeng glanced at Dan Qiu Sheng and sneered in his heart. He naturally knew that there was a sequence for adding the materials, which was clearly written on the recipe.

After all, whichever medicinal ingredient is put into the cauldron first determines which one will be refined first. Putting them all in at once will be like a hodgepodge. The Seven Profound True Fire will refine all the medicinal ingredients, and then mix them together and turn them into impurities.

Alchemy is like chemistry, there are strict requirements on who reacts chemically first.

So why did he do this? Of course it wasn't to show off, but just because it was too troublesome... Well, actually it was just to show off.

After pouring in the herbs, Gu Qingfeng immediately closed the lid of the cauldron and then activated his master-level soul power and fire-controlling talent.

Under the control of soul power and fire-controlling talent, the seven-colored lotus-like flame in the alchemy cauldron that no one could see instantly split into more than a dozen parts. Each flame wrapped one or two medicinal herbs and began to be refined separately.

If Dan Qiu Sheng saw this scene, he would surely be stunned, because this is equivalent to setting up more than ten alchemy furnaces at once and refining the elixir at the same time, which is equivalent to doing more than ten things at once. It requires extremely huge soul power to perform such delicate operations.

Although Dan Qiu Sheng could barely perform this alchemy technique, he could never put them all into one alchemy furnace and refine them at the same time.

Because the distance is too close, the flames will interfere with each other.

Dan Qiu Sheng couldn't do it because he only knew how to control fire, but couldn't control fire like Gu Qingfeng.

With the help of the fire-controlling talent, more than a dozen flames did not interfere with each other and were in an orderly manner, like automatic robots, refining their own shares automatically.

The medicinal materials were rapidly burned into a delicious and juicy medicinal liquid. Under the refining of the Seven Mysterious True Fire, all impurities were removed one by one, leaving only the essence.

Then Gu Qingfeng used his master-level soul power to control the liquid medicine and began to combine them in pairs in order. Whoever reacted with whom would produce what substance first, and then the new substance produced would react with other substances.

Countless chemical reactions take place simultaneously, increasing the efficiency of alchemy several times.

Just wait another stick of incense and the bone-rotting pill will be ready.

A smile of confidence appeared on Gu Qingfeng's lips.

However, in Dan Qiu Sheng's eyes, Gu Qingfeng simply poured all the herbs into it, and then did nothing but stand there.

It's just like the alchemy furnace can automatically make elixirs.

Isn't this nonsense?

In the past, when he was refining pills, he needed to control the temperature at all times. After all, the flames would explode and were extremely difficult to control. If he was not careful, the temperature would be a little higher or a little lower, which could lead to failure. He also needed to use his soul power to keep a close eye on the changes in the medicinal materials, and use the right temperature of flame according to what state they turned into. This was all delicate work. No one could just pour everything in and then leave it alone.

Even when you are cooking, you still need to stir-fry and control the temperature, let alone making medicine.

It's a pity that a whole pot of excellent medicinal materials was wasted.

Dan Qiu Sheng secretly felt sorry, but when he thought of the pills Gu Qingfeng took out, he instantly felt that it was worth it. The only thing that worried him now was, what if this kid lost and refused to admit his mistake?

Thinking of this, Dan Qiu Sheng couldn't help but move closer to where Gu Qingfeng placed the pills.

He decided that if Gu Qingfeng refused to admit his mistake, he would simply pick up the pills on the ground and put them in his pocket. No matter how powerful Gu Qingfeng's background was, the power behind him would not offend a master alchemist for a bet.

After one stick of incense.

"Done." Gu Qingfeng said lightly, and was about to lift the lid.

Dan Qiusheng kept sneering. "It would take me an hour to refine it at the fastest speed. You can do it in just one stick of incense? I'm afraid the furnace will explode as soon as you lift the lid, right?"

He calmly took two steps back, avoiding the alchemy furnace, and at the same time got one step closer to the hundreds of bottles of pills, and even started to take them.

Just as he put the first medicine bottle into his arms, suddenly a strange medicinal fragrance wafted away.

Dan Qiusheng froze in his tracks. This familiar medicinal scent! How could it be possible!?

He suddenly looked towards Gu Qingfeng, and saw fourteen round, purple-red pills lying quietly in Gu Qingfeng's hands.

It was the Bone-Rotting Pill.

Just as the more beautiful something is, the more dangerous it is, and just as roses all have thorns, the more toxic the poison, the brighter its color.

"What are you doing, old man? You've already lost, and you still dare to steal my pills?"

Dan Qiu Sheng was so shocked at this moment that he just exclaimed that it was impossible. He could not listen to Gu Qingfeng's ridicule at all.

He appeared beside Gu Qingfeng in a flash, snatched the Bone-Rotting Pill and looked at it carefully.

The more I watched, the more shocked I became.

This smell, this color, it's definitely the Bone-Rotting Pill!

But how is this possible? It takes one stick of incense time to refine fourteen of them in one furnace, and this is the first time I'm doing this?

Even someone as strong as me would need an hour, and at most five pills in a furnace. But this kid made fourteen in one furnace. Doesn't that mean that not a single ingredient was wasted?

"Impossible! It must be an illusion. When did you cast an illusion on me?" Dan Qiu Sheng said in disbelief.

"Tsk." Gu Qingfeng said disdainfully: "If it's an illusion, you'll know if you try it."

Gu Qingfeng was teasing him on purpose, but Dan Qiu Sheng looked paranoid and determined that the Bone-Rotting Pill couldn't be real. He thought that Gu Qingfeng must have used some means to make a pill that looked exactly the same.

So he simply picked up a bone-rotting pill and swallowed it.

In just a moment, Dan Qiu Sheng's eyes bulged, and then his face turned pale. He spat out a mouthful of blood, and then he felt his bones soften, as if his whole body was about to melt.

"It's actually... true!" Dan Qiu Sheng said in shock while spitting blood.

Gu Qingfeng was startled: "Hey, hey, hey, old man, don't be dead, do you want to scam me?"

He didn't expect that the old man was so honest and would actually test the poison on himself.

Dan Qiu Sheng also reacted at this time, and hurriedly took out the detoxifying pill for the Fu Gu Dan and swallowed it, and then he gradually got better.

After he recovered, Dan Qiu Sheng looked at Gu Qingfeng with a complicated expression.

With mixed feelings in his heart, he still didn't understand why this kid threw all the herbs in at once and then just stood there and watched as the pill was automatically refined. Could this be a new alchemy technique that has emerged recently?

"How did you do it?" asked Dan Qiusheng.

"Isn't it enough to have hands?" Gu Qingfeng said as he walked to Dan Qiu Sheng, stretched out his hand and took out the bottle of pills that he had just taken away from his arms, and by the way, he also took away the bone-rotting pill that he had refined.

Dan Qiu Sheng stared at it blankly but did not try to stop it.

He didn't react until Gu Qingfeng was about to take away the Seven Profound Cauldron.

"Wait, you have to tell me how you did it, otherwise you're cheating and this game won't count."

Gu Qingfeng got angry when he heard this: "Old idiot, stop taking advantage of your age. You have to accept the loss, you know? Just because you say it doesn't count, it doesn't count. How can you be so shameless? You still want to know my unique alchemy method? Dream on!"

Dan Qiusheng's face turned red and white, but he still couldn't suppress his curiosity and said, "Mr. Gu, I don't ask you to teach me your unique skills. As long as you can solve my doubts, I am willing to exchange treasures for you."

As he spoke, he took out a pill.

"This is a realm-breaking pill I got from an ancient relic. It can help warriors increase their chances of breaking through. Taking this pill can increase the chance of breaking through to the Inner Qi realm by 80%, the True Qi realm by 50%, and the Gang Qi realm by 20%. It is ineffective for Grandmasters. This pill is worth a thousand gold. As long as you can solve my doubts, I will give it to you."
