Chu Han devoted all his attention to the thin booklet "Heaven and Earth Furnace", and firmly remembered every word in "Heaven and Earth Furnace", as if he had engraved it into his soul.

Syllable!

Chu Han closed the Heaven and Earth Furnace, took the book back into the storage ring, and slowly closed his eyes.

At this moment, in Chu Han's mind, words and patterns are piecing together different pictures.

Heaven and earth are furnaces and stars turn into fire!

Chu Han felt more and more that this set of cheats was terrifying, both in terms of complexity and function, far exceeding the Thunder Fire Separation Method.

Minutes and seconds passed.

Chu Han was always immersed in research, carefully studying every detail, and no one disturbed him in this Yunlai Inn.

Before I knew it, three days had passed.

During these three days, Chu Han had been studying in retreat, and Shen Bing'er, Qi Ju, Feng Han, and Junchen did not come to disturb Chu Han, and they were all cultivating in their respective rooms.

"I see!"

Suddenly, Chu Han opened his eyes suddenly, and a flash of ecstasy flashed in his eyes.

"Star fire, heaven and earth furnace, amazing, really powerful!"

Chu Han couldn't help but exclaim, he waved his hand suddenly, his fingertips rhythmized in the space, and suddenly a spiritual power with spatial fluctuations burst out, forming an almost transparent Ding Furnace in front of him.

Heaven and Earth Furnace!

Chu Han stared at the Ding furnace in front of him, which seemed to be formless and substantial, but in fact it was all-encompassing, revealing mysterious fluctuations.

"I have mastered the Xingchen Fire and the Heaven and Earth Furnace, now let's try refining some pills!"

Chu Han couldn't wait to use the Heaven and Earth Furnace to refine the pill, his eyes rolled, and after a little thought, he had the answer in his heart.

"Refining the Xuanling Pill! Shen Bing'er will soon break through to the Earth Xuanling Realm, and this pill still has some effect on her!"

Chu Han nodded silently, Shen Bing'er is still the strength of the Qi Transformation Realm, but this is what Chu Han wants Shen Bing'er to suppress, just for a better foundation, but the suppression can't be suppressed for long.

Chu Han believed that it wouldn't take long for Shen Bing'er to break through the Qi Transformation Realm and enter the Spirit Realm, and the Spirit Realm would not bother Shen Bing'er for too long.

Three-pattern elixir, Xuanling pill.

It can increase the spiritual power of the Earth Xuan Realm martial artists, but it is only the most effective for the Earth Xuan Realm martial artists.

Chu Han thought very clearly, since he needed alchemy, he would refine something that could be used, and it would not waste time or medicinal materials.

"Let's get started!"

Chu Han had refined the Xuanling Pill, and the Xuanling Pill's recipe and refining method were all imprinted in his mind, and there was no doubt at all.

Whoa!

Chu Han moved his wrist, and a pile of medicinal materials appeared in the room, these medicinal materials were all Yu Haoyang's collection, and the medicinal materials stored by the president of the Tiannan City Alchemist Guild were almost comparable to the medicinal materials library of the Jiang Xue City Alchemist Guild.

呲呲呲......

With a wave of his palm, Chu Han shuttled between the medicinal materials with the power of Lei Yan, as if it was attractive, extracting all the medicinal materials needed to refine the Xuanling Pill.

Airplanes!

Chu Han's eyes flashed, and with a flip of his hand, the invisible furnace with spatial fluctuations appeared out of thin air, which was the heaven and earth furnace that Chu Han had just learned.

Shout!

Chu Han's finger lightly clicked, and a thunder flame electric flower floated through the air, landed under the Heaven and Earth Furnace, and suddenly bloomed.

WhewW......

A scorching flame rose and instantly covered the Heaven and Earth Furnace, the scorching heat distorting the air around it.

Whoa......

Chu Han controlled the medicinal materials needed to refine the Xuanling Pill, and these medicinal materials crossed parabolas in the air and fell into the Heaven and Earth Furnace.

"Star Fire!"

Chu Han's brows furrowed tightly, and the power of the thunder flame on his wrist changed suddenly, and in an instant, the fire under the Heaven and Earth Furnace changed, and the terrifying flames were like deep stars, emitting strange fluctuations.

As the medicinal materials continue to enter the heaven and earth furnace, the temperature of the star flame continues to change, sometimes it becomes high, sometimes it is low, and different changes occur with the refining of different medicinal materials.

WhewW......

As the flames burned, Chu Han gradually realized something.

This is where the Heaven and Earth Furnace and the Star Fire are the most powerful match.

Chu Hancai used the Star Fire in the quenching competition, but at that time he didn't have the Heaven and Earth Furnace, he needed to use the Star Fire to heat up the space medium, and then use the space medium to warm the medicinal materials.

However, heaven and earth furnaces are different.

The Heaven and Earth Furnace is paired with the Star Fire, as if there is no medium, and the temperature of the Star Fire can be directly roasted on the medicinal herbs.

At the beginning, Chu Han was still a little uncomfortable.

For a long time, alchemy is based on the temperature of the Dan furnace, and the increase or decrease of the flame temperature is to change the temperature of the Dan furnace, and the temperature of the Dan furnace is to adapt to the temperature of the medicinal materials.

With the medium of Dan furnace, there is a great need for superb fire control technology.

However, now it is different, Chu Han can use the Xingchen Fire to directly cauterize the elixir, omitting the intermediate steps, and he can directly adjust the temperature of the Xingchen Fire to adapt to the temperature of the medicinal materials.

The simplicity of such steps is an irreparable difference in alchemy techniques, but under the combination of Xingchen Fire and Heaven and Earth Furnace, this problem is perfectly solved.

WhewW......

As the flame of the stars burned, the medicinal materials in the Heaven and Earth Furnace gradually fused, forming drops of essence containing rich medicinal properties.

"Fusion Potion!"

Chu Han was surprised in his heart, he didn't expect that with the cooperation of the Heaven and Earth Furnace and the Star Fire, refining the pill would become so easy.

The quenched liquid was constantly bubbling in the furnace, and under the squeeze of the power of space, it fused together little by little.

Grunt......

The inner furnace of heaven and earth rotates, so that the liquid medicine does not stop rotating.

As the speed of rotation gets faster and faster, the quenching of the star fire becomes more and more symmetrical.

It didn't take long for a wisp of medicinal incense to hit......

"Condense into Dan!"

Chu Han's eyes flashed, he didn't expect that the first time he used the Heaven and Earth Furnace and the Star Fire to refine the pill would be so smooth, he was still a little uncomfortable with this Heaven and Earth Furnace, and it was more difficult to control than the traditional Dan Furnace, but he had figured out some doorways, and he was confident that the next refining would be better.

The star fire was extinguished, and the Heaven and Earth Furnace rotated rapidly, causing the liquid medicine in it to rotate non-stop, constantly squeezing and converging together.

The liquid medicine formed a more round ball, constantly permeating with heat, and the clear three Dan lines slowly formed.

Dancheng!

The corners of Chu Han's mouth slightly curled up with a touch of evil arc, this experiment gave him a deeper understanding of the mastery of the Heaven and Earth Furnace.

Shout!

The Xuanling Pill flew into Chu Han's jade bottle, and as Chu Han covered the jade bottle, only this heaven and earth furnace was left in the space in front of him.

"I'm still a little unskilled, I should refine some more pills. ”

Chu Han took a deep breath, after he discovered the strength of the Heaven and Earth Furnace, he made up his mind to practice the Heaven and Earth Furnace well.
