"So this is the alchemy furnace."

Lin Yu looked at the object in front of him that looked like a huge furnace and said with some surprise.

"yes, haven't you ever seen one?"

Cheng Xing'er looked at Lin Yu with disdain, as if she was looking at a dirt bun.

Lin Yu smiled and didn't take Cheng Xing'er's words to heart.

"Yes, it's the first time I've seen this alchemy furnace."

In Lin Yu's mind, the concept of an alchemy furnace only existed in those fantasy novels of Blue Star.

He felt that these Dan furnaces should be relatively small.

"It's so big, no wonder it has to be put in a special alchemy room."

Cheng Xing'er pursed her lips, but still explained to Lin Yu.

"This alchemy furnace is just relatively ordinary, and the flame needed for alchemy needs to trigger the earth fire."

"Ordinary flames can't refine some medicinal herbs at all."

Lin Yu thought about it, it was also the same reason, after all, some of these medicinal materials were more difficult to deal with than gold and stone.

If you can really make a fire and make alchemy, then wouldn't this alchemist be all over the street?

But Cheng Xing'er then spoke again.

"It's not that there are no small alchemy furnaces, it's just that the price of small alchemy furnaces is more than ten times that of this kind of alchemy furnace."

"These alchemy furnaces are all made by famous alchemists, and basically those famous alchemists will have their own alchemy furnaces."

"Moreover, if an alchemist wants to use this kind of Dan furnace, he must practice the previous fire-attribute technique or combat technique."

Lin Yu gave her a thumbs up.

"I didn't expect you to be a big person, but you know a lot."

"That's, don't look at who I am!"

Cheng Xing'er puffed out his chest and looked proud.

"And oh, I said I'm not small!"

Cheng Xing'er glanced at Lin Yu fiercely, and threatened with teeth and claws.

"Okay, okay, got it."

Lin Yu didn't even bother to be perfunctory.

"Are you here to do alchemy?"

"I've heard that alchemists will refine very delicious pills......

Speaking of this, the saliva at the corner of Cheng Xing'er's mouth was about to flow out.

However, Cheng Xing'er thought of something and glanced at Lin Yu suspiciously.

"But it's the first time you've even seen an alchemy furnace, and you don't seem to be an alchemist."

Lin Yu nodded.

"It's true that I'm not an alchemist, and I'm not here for alchemy."

"It's just that there were a few pills that were not of good quality before, and I plan to refine the Cheng Dan again."

Cheng Xing'er didn't seem to know much about pills, and when she knew that Lin Yu was not an alchemist, she was a little bored.

She found a place to sit down with a big grin, her little eyes searching around.

Lin Yu looked at her like this, didn't care about her anymore, took out the porcelain vase and hydrangea and put them on the table.

Then he came to the alchemy furnace, and there was a jade slip next to the alchemy furnace, which recorded the use of the alchemy furnace.

Lin Yu immersed his divine sense in it and learned about it.

The first thing to do when using the alchemy furnace is to activate the formation in the Dan furnace, and the function of this formation is to extract the earth fire into the Dan furnace.

Then the alchemist can control the formation through the True Qi control formation, and never control the firepower of the alchemy furnace.

In fact, the operation method of this alchemy furnace is not difficult, the difficult thing is to master the heat and understand the combination of medicinal materials in the future.

After all, if an alchemist wants to make a pill, he must first have a pill, except for some more popular pills, many alchemists will treat them as treasures after researching the pills.

Unless it is a personal disciple, Dan Fang would rather rot in a coffin than pass it out easily.

After Lin Yu read the introduction, he began to experiment for a while.

By the time Lin Yu felt the same, Cheng Xing'er had already fallen asleep on the seat.

Lin Yu looked at Cheng Xing'er's sleeping appearance and smiled dumbly.

He shook his head, removed the roots of the hydrangea grass, threw the leaves and main stems into the alchemy furnace, and then activated the formation.

With a whistling sound, bursts of heat emanated from under the Dan furnace, and even the temperature of the alchemy room was a few points higher.

Cheng Xing'er seemed to feel something, rolled over and continued to fall asleep.

The seats of this alchemy furnace seem to be specially made, and they look larger than usual, and Cheng Xing'er's physique is just right to lie in it.

Looking at her comfortable appearance, Lin Yu felt that his mood would be much better.

Retracting his gaze towards Chengxing'er, Lin Yu patiently adjusted the firepower of the alchemy furnace.

Seeing this method in the jade slip before, Lin Yu felt that it was enough to have a hand, but now he has started it himself.

Lin Yu had only one thought in his heart, and that was that he didn't seem to have any hands.

After a period of scrambling, Lin Yu still managed to melt the hydrangea into juice.

As the flame burns, the juice becomes more and more viscous.

Lin Yu took out a few herbs from his arms again.

These herbs were all collected by him in the small courtyard where Jiu Lao lived, and they were not particularly precious, and Jiu Lao didn't care about his use.

Lin Yu threw an herb that looked like a dog's tail flower in the Blue Star into it, and this herb was called Qingxin Flower.

It doesn't look very good-looking, but it is a good auxiliary material that can neutralize the medicinal properties of hydrangea.

Although the Purple Star Pill and the Purple Hydrangea both have a purple in their names, the Purple Hydrangea is a strong herb, and the Purple Star Pill is a cold pill.

If the two are allowed to come into direct contact, not only will they not be able to improve the quality of the Purple Star Pill, but it may even have the opposite effect, making the Purple Star Pill a waste pill.

After the Qingxin Flower also melted, Lin Yu put in the remaining herbs again.

The effect of these herbs is to maximize the effect of hydrangea grass, similar to the effect of medicine.

After everything was ready, Lin Yu carefully added the Purple Star Pill to it and adjusted the firepower of the alchemy furnace again.

Lin Yu really didn't dare to be distracted this time, because once the heat was not mastered, this Purple Star Pill would turn into coke.

Lin Yu's eyes stared at the three Purple Star Pills in the alchemy furnace, this Purple Star Pill was already a formed elixir, and if you want to refine it, you must first turn them into liquid again, which is a great test of the alchemist's ability to control.

Fortunately, Lin Yu had countless experiences of reversing his true qi in his future dreams, and his control over his true qi was not even comparable to Su Ke'er's now.

As time passed, the sweat on Lin Yu's forehead began to drip into his eyes, giving him a sour feeling.

But he didn't dare to wipe the sweat, and carefully controlled the input of true qi.

By the time the true qi in Lin Yu's body was used, these three Purple Star Pills finally began to melt.

Lin Yu's spirit perked up, and he increased the input of true qi, and slowly, the Purple Star Pill began to merge with the medicinal liquid in the alchemy furnace.

Lin Yu breathed a sigh of relief, and the next thing was simple.

After a period of boring waiting, bursts of tempting fragrance emanated from the alchemy furnace, and even Cheng Xing'er woke up.

She looked at the three round pills in the alchemy furnace, and she couldn't take her eyes off.
