After Xing Lao had prepared everything according to what Sheng Jiu said, the alchemy continued.

After the first breeze grass was thrown into the Dan Furnace, after the Holy Nine started again, he opened the Ice Purple Thunder Furnace for a while.

"I didn't expect that in such a short period of time, the breeze grass has formed ice ballast."

After seeing the situation inside, Sheng Jiu's brows furrowed.

"Do you want to write this down?" Elder Xing heard what Sheng Jiu said and asked.

"There's no hurry!" I'll try another one again.

Qingfeng Grass Shengjiu picked a lot here, and wasted some of it, but he didn't care, because this medicinal herb was very common in the depths of the back mountain.

After saying that, she took out the breeze grass inside, studied it carefully for a while, then put the ice ballast breeze grass aside, and then put another intact breeze grass into the Dan furnace.

Based on previous speculations, Sheng Jiu believed that Qingfeng Grass could do all of this in just twenty breaths from entering the Dan Furnace to completely forming ice ballast.

Thinking in his heart, the moment the roof of the furnace was closed, the Holy Nine began to clock in.

After she had breathed twenty times, she reached out and suddenly opened the Dan furnace in front of her.

As she thought, the breeze grass was completely frozen ballast.

However, in order to verify his guess more accurately, Sheng Jiu used another Qingfeng grass to conduct an experiment.

Only this time the time to open the roof of the furnace was after nineteen breaths, although there was only one breath in between, but there was an essential difference between the two breezy plants.

"Okay, old! Record that Breeze Grass has twenty breaths. ”

With this result, Sheng Jiu said to Xingtian.

The other party didn't ask, and according to what Sheng Jiu said, he quickly recorded it.

After the record, Xingtian looked at the Holy Nine again, but at this moment, the Holy Nine carefully looked at the Qingfeng grass that had formed ice ballast before.

After a while, he beckoned: "Lingyun!" Go to the kitchen and wash the garlic mortar and bring it to you. ”

"It's the master!" Ling Yun answered, turned around and ran towards the kitchen.

Xingtian felt strange and asked curiously: "This alchemy, you still use garlic mortar?" ”

This garlic mortar, also known as Shi Zhongzi, some people also call garlic mash, although the name is different, but they are all the same utensil.

"I don't want to, but in the current situation, I need to test my suspicions." Sheng Jiu replied flatly.

If she weren't a weirdo, she wouldn't have done so many things, but as Sheng Jiu's research deepened, a whole set of ideas sprouted in his heart.

And now it's just a matter of validating that idea.

"Lingyun has come and gone, it will take a while, can you talk about it first?" Xingtian walked over and asked.

"Look at this Qingfeng grass, in the Ice Purple Thunder Furnace, it only took twenty breaths for all of it to form ice ballast, and this one is the one after nineteen breaths, although the two are only one breath apart, but the degree of freezing is different."

"What do you say this Ding Dan furnace is for freezing herbs into ice ballast?" As he spoke, Sheng Jiu suddenly asked rhetorically.

"This! The old man is not an alchemist, and his head is not as flexible as yours, so he doesn't understand. Xingtian replied directly.

"In my opinion, this cold ice purple thunder furnace has a great origin, and the reason why it freezes the herbs, in fact, the purpose is very simple, the ordinary Dan furnace is to burn the medicinal materials with flames for refining, in the process of incineration, the medicinal materials at the right temperature, directly into medicinal powder, and freeze the medicinal materials, and the medicinal materials that are beaten with ice ballast by external force can also achieve the same effect."
