The autumn wind was blowing, and the bushes and jungles on the isolated island began to be covered with a layer of yellow.

However, on the cliffs by the sea, there is a medicine garden, which looks lush.

Among them, there are hundreds of elixirs, which are full of rich medicinal fragrance, and the color is also different from the turquoise of other elixirs, showing a strange dark green!

This is the third month that Xia Yin and Zhang Rouran have come to the island.

Two figures quickly walked towards the cliff from a distance, and a small figure jumped up and down beside the two of them.

From a distance, Zhang Rouran took a few deep breaths, and looked at Xia Yin suspiciously: "Hey, how did I smell a strong medicinal fragrance, and ...... You are mysterious, what are you bringing me here?"

Zhang Rouran has never been to this cliff.

Xia Yin smiled, but did not explain, but continued to walk towards the cliff.

The monkey Xiaosi jumped on Zhang Rouran's shoulder, squeaked, and pointed in the direction of the cliff with one paw, as if he wanted to tell Zhang Rouran something......

Zhang Rouran looked at the monkey Xiaosi with a smile: "Little guy, like your master, he chatters all day long!"

Soon, the two and one beast came to the edge of the cliff.

At this time, the girl Zhang Rouran was already stunned by the scene in front of her!

The one-acre size medicine garden is full of all kinds of elixirs.

Moreover, the girl found that there were many kinds of elixirs among them, which were rare varieties that she had collected in the secret realm cave back then, but what she harvested at that time were all elixirs and seeds that had already died for many years, and now these same elixirs in the medicine garden are flourishing.

The most unbelievable thing for the girl was the hundreds of elixirs with a strong medicinal fragrance, at least hundreds of years old.

"Xia Yin, this ...... What's going on?"

Zhang Rouran looked at Xia Yin with a shocked expression.

More than a month ago, he used the residual effect of the void spirit body, opened Xia Yin's storage ring, and took out everything, in addition to a large number of daily necessities, including a wide variety of elixir seeds......

This medicine garden was opened up and planted by Xia Yin, there is no doubt about it.

But where did these hundreds of elixirs that were at least a hundred years old come from?

Xia Yin glanced at Zhang Rouran, and his face became solemn: "This is my biggest secret, fellow Daoist, you remember, this matter must not be exposed, otherwise it will ......"

Zhang Rouran nodded: "You don't need to say it, I understand!"

For a girl, Xia Yin's ability to share the biggest secret with herself is a kind of absolute trust, which is enough......

Xia Yin couldn't help but let out a long sigh of relief.

Originally, I was still worried about how to explain this matter clearly, but I didn't expect Zhang Rouran to get to the bottom of it at all.

"What about Xiaoding and Yuehua Jinyan I asked you to bring?" asked Xia Yin.

Zhang Rouran smiled, and a small tripod flew out of the storage bag.

This is the girl's own backup.

For Zhang Rouran, who has a void spirit body, many materials need to be melted and refined with a furnace ding.

A wisp of flame, bound by an invisible force, floated in the small ding.

Yuehua Jinyan, originally in Xia Yin's storage ring, after Zhang Rouran helped open the storage ring last time, Xia Yin simply handed over this wisp of flame to the girl for safekeeping.

"What are you...... Do you want to do alchemy?"

Zhang Rouran asked with a surprised face.

Xia Yin nodded slightly: "Yes, I must refine the pill, otherwise I won't be able to cultivate at all, and Si'er also needs the pill for food!"

Zhang Rouran smiled: "I also need the elixir, although the Void Spirit Body is seriously damaged, but I am a foundation building monk, but the mana is seriously consumed, if there is the kind of pill you gave me before, and the amount is enough, I can still slowly cultivate the mana back!"

Xia Yin nodded: "Yes, so alchemy is the most urgent matter now, but I don't have the slightest mana, and we don't have the earth fire, now I can only try you to control Yuehua Jinyan, use it to try, and see if you can do alchemy!"

Zhang Rouran showed a wry smile on her face: "With the power of space that I have left now, I should be able to control Yuehua Jinyan reluctantly, but I can't do alchemy!"

"I will, as long as you control the heat, I will do the rest, so that although the alchemy is very inefficient, it is also the only way, so I can only try!"

Zhang Rouran nodded slightly.

Next, as if building a stove, the two of them found a lot of stones, built them into a circle, up to one meter, hollow, and then put the small ding up, as if they were ready to make a fire to cook.

Next, Zhang softly bent his fingers a little, and the flames in the ding flew into the girl's fingertips.

Even if there is no mana in her body, but after all, the girl has a void spirit body, and for Zhang Rouran, such an act is like a mortal reaching out to take something, which is very common.

Zhang Rouran stretched out her left index finger and lightly touched it on the flame of Yuehua Jinyan......

The invisible restraint that wrapped Yuehua Jinyan quietly opened a hole at the top, as if a teapot with the lid removed, allowing a wisp of Yuehua Jinyan's flame to emerge.

A scorching breath erupted, instantly turning into a boiling heat wave.

Xia Yin, who was caught off guard, instantly felt as if he had fallen into the flames!

On the other hand, there is an invisible force on Zhang Rouran's body to protect his body, and that scorching breath cannot contaminate his body at all.

"This ...... This month Hua Jinyan is so terrifying!"

Xia Yin couldn't help but marvel that his body was so strong that he also felt a burning sensation.

Zhang Rou bent his fingers a little again, making the flames coming out of Yuehua Jinyan a little smaller.

Even so, Xia Yin next to him still felt the rolling heatwave.

The monkey Xiaosi had already fled, running out of a distance of dozens of feet, squeaking in fright.

Xia Yin was not surprised.

"Zhang Daoyou, you control Yuehua Jinyan to fly below Xiaoding, and then try to adjust the size of the firepower!"

Zhang Rouran nodded slightly, flicked her fingers, and Yuehua Jinyan flew to the bottom of Xiaoding on the "stove", quietly levitating.

A wisp of flame burned silently at the bottom of the small ding.

The terrifying heat quickly made most of the small tripods turn red......

"Okay, good, it's really good, control the firepower a little less!"

Xia Yin commanded happily, but he ran to the medicine field in the distance, quickly collected more than twenty hundred-year-old elixirs, held them in his arms, and then rushed back.

Next, Xia Yin removed more than 20 kinds of elixirs from the root soil, and then placed them on the ground very regularly, but his eyes were staring at Xiao Ding: "The firepower is smaller, well, it is smaller, ah, no, no, no, no, don't be too small, a little bigger......"

With the continuous command, Zhang Rouran also cooperated very well to adjust the invisible force that bound the flames, controlling the size of the flames......

In the end, the flames reached a level that Xia Yin was very satisfied with.

"That's it, keep up the firepower!"

Zhang Rouran nodded slightly, letting Yuehua Jinyan quietly levitate below Xiaoding, swaying slightly.

"Okay, next, let's start practicing the control of the flame size, based on the current flame, set the tenth level flame size, come, downgrade one level ......"

Zhang Rouran didn't know what the so-called first level was, so he could only reduce the temperature of the flame at will.

"It's too much, a little bit more, well, a little more...... Yes, yes, that's it, this is to downgrade one level, and now restore the base flame ......"

With Xia Yin's continuous command and adjustment, for most of the day, the two finally formed a tacit understanding, and Zhang Rouran was able to quickly adjust the size of the flame according to Xia Yin's instructions!

This is a very crucial step in alchemy.

In the past, in the house of earth fire under Tianling Peak, Xia Yin could do whatever he wanted by controlling the earth fire switch and adjusting the size of the flame, but now, this action can only be controlled by Zhang Rouran, and it must be done with tacit understanding.

Xia Yin was not in a hurry, and continued to practice this kind of cooperation with Zhang Rouran, constantly adjusting the size of the flames......

Three days later, the tacit understanding between the two people had reached the point where as soon as Xia Yin spoke, Zhang Rouran adjusted the flame to the state that Xia Yin said.

So, Xia Yin began to try alchemy......

According to Xia Yin's instructions, Zhang Rouran adjusted the flame to the right level.

Xia Yin stared at Xiao Ding, paying close attention to the changes in the temperature in the Ding.

Although the mana was lost, the powerful spiritual power still existed, which allowed Xia Yin to easily control the temperature changes in Dingzhong.

Suddenly, Xia Yin quickly grabbed the five elixirs on the ground and threw them into the ding......

"The temperature is two levels!" Xia Yin quickly commanded.

The flames under the ding changed suddenly, and the temperature instantly increased by two times!

A faint medicinal fragrance slowly wafted out from the ding......

After a while, all the five elixirs in Dingzhong turned into medicinal juice.

"Temperature down one level!"

While Xia Yin commanded, he quickly grabbed the three elixirs on the ground and threw them into the dingzhong.

And Zhang Rouran flicked his fingers in the void, and the flames under the ding slightly converged......

After three days of practice, both of them seem to have a very tacit understanding!

Next, Xia Yin continued to put elixirs into the dingzhong, and at the same time instructed Zhang Rouran to adjust the size of the flames......

Half a day later, all the elixirs on the ground had been thrown into Dingzhong and turned into juice.

And the flame under the ding has always maintained a certain temperature, continuing to refine the medicinal juice of the ding.

Xia Yin gently covered the lid of the tripod......

Next, it is the most critical "opening the furnace", which is the last key step in whether or not you can become a Dan.

During this period of time, the control of the heat needs to reach a point of subtle control, and there must be no mistakes.

Xia Yin directly closed his eyes, and his powerful spiritual power was released, enveloping the entire Xiao Ding, closely watching the changes in the Ding Chinese Medicinal Juice, and at the same time, every once in a while, he would issue instructions in his mouth to ask Zhang Rouran to adjust the size of the flames......

This process lasted for an hour!

"Ten levels of temperature increase!"

Xia Yin's voice was short and high-pitched.

Zhang Rouran also bent her fingers a little wisely......

Call!

The flames surged suddenly, and a wave of heat swept in all directions.

At this time, Xia Yin couldn't care about the burning and stinging sensation on his body, his eyes were closed, and he kept paying attention to the changes in Dingzhong that had gradually solidified from the medicinal juice......

"Ceasefire!"

With Xia Yin's shouting, the flames under the ding were suddenly extinguished.

"Open the furnace!"

Xia Yin roared loudly in his mouth, and then quickly reached out and pulled the hot lid off.

Only a strong body like Xia Yin dares to reach out and uncover the hot lid!

Rumble!

A scorching wave of air rose into the sky, flooding with bursts of white mist.

Xia Yin and Zhang Rouran both couldn't wait to look towards Dingzhong.

"Haha, it's done!"

In the cheers, Zhang Rouran jumped up excitedly, hugged Xia Yin, and rode on Xia Yin's waist very unladylikely......

"Hey, Xia Yin, what are you carrying, it makes me so uncomfortable!"

"Ahem......"
