The time of the cultivator always passes inadvertently, and before you know it, the time has come to the month of the water season in the year 3011 of the Zixiao Age.

Elixir Valley, floating island, Elixir Xuan, in the independent courtyard of Yan Tianzhen.

Hua Yu and Lan Yumeng were busy in the alchemy pharmacy.

Hua Yu used his spiritual power to manipulate a turquoise vine into a white jade bowl, and at the same time used a secret method to urge the white jade bowl.

After a while, some transparent and vibrant droplets were extracted from the cyan vines, and then the extracted jade liquid was introduced into the jade bottle with spiritual power, and after one process was completed, the next one was extracted and repeated.

The blue-green vines are called "evergreen vines", and the jade liquid extracted is the essence of the vines replaced with "rebirth liquid", and the white jade bowl used to extract the "rebirth liquid" is specially used to extract the essence of various elixirs, and it is one of the common tools for refining medicine.

Hua Yu was busy, Lan Yumeng was not idle next to Hua Yu, I saw her left palm up, a small and delicate incense burner suspended on her palm and constantly rotating, and her right hand was constantly pinching the seal.

Wisps of red smoke floated out of the hollow holes in the lid of the incense burner, and these red smoke were carefully stored in a transparent glass bottle by Lan Yumeng.

After a while, there was no more red smoke floating out of the incense burner, Lan Yumeng hurriedly opened the lid of the stove, there were some gray dust in the incense burner, these dust were her real purpose, as for those red smokes were just incidental things.

It may be that it is difficult to urge the incense burner, a layer of fragrant sweat appeared on Lan Yumeng's forehead, the face towel he wore on his face was also close to his face, and his ears became slightly red. Somehow, looking at this kind of Lan Yumeng, Hua Yu couldn't help but have an indescribable strange feeling in his heart.

Lan Yumeng also seemed to feel that Hua Yu was watching her, and turned her head to look at Hua Yu for a moment before asking, "Senior Brother Yu, what's wrong?"

Hua Yu hurriedly shook his head and suppressed the strange feeling in his heart, and then said: "Senior Sister Yumeng, urging the 'Medicine Refining Furnace' is more consuming of vitality, so it's better to change me for a while!"

Lan Yumeng wiped the fragrant sweat from his forehead and said with a smile: "Okay then! Senior Brother Yu, you come."

Hua Yu took the incense burner, this incense burner is also one of the common tools for refining medicine, called the "alchemy furnace", open the lid of the furnace, put in some brown rhizomes, and then cover the lid, the left hand urges the secret method to suspend the "alchemy furnace" in the palm of the hand, and the right hand keeps pinching the seal.

The brown rhizome is the rhizome of 'Rehmannia Wood', and the last gray dust is the finished product after refining through the "alchemy furnace", which is called 'leaving the dust'.

"Senior Sister Yumeng, what kind of elixir do you say will be refined by real people with these elixirs we dealt with today?"

"Well, I know this, I heard a real person say that he was going to refine the 'Huitian Replenishing Yuan Liquid' today, as if someone entrusted a real person to refine it."

"Oh, is it refining the 'Heaven Replenishing Liquid', this is a great medicine to replenish vitality and make up for the damage to the foundation, I don't know who hurt the foundation?"

"I don't know, the real person didn't say it".

"Oh...".

"What are you two discussing?Did I get you all in order?" While the two were discussing, suddenly, a very beautiful voice appeared in the ears of the two of them, and then a beautiful figure appeared in the alchemy

When the two of them saw the visitor, they immediately replied respectfully: "The other elixirs have been dealt with, and now it's time for the 'Rebirth Liquid' and 'Leaving the Dust'."

"Well, yes, today I want to refine the very cherished 'Huitian Replenishment Liquid', the opportunity is rare, you can watch from the sidelines, and help by the way."

"Thank you to the real person" After hearing the words of the real person, the two of them showed excitement on their faces, and thanked them excitedly. Being able to have the opportunity to watch a real person refine the 'Huitian Replenishing Yuan Liquid' is a difficult opportunity, which is very helpful for the two to improve their knowledge of alchemy.

Although there are many recipes for the production of elixirs that can be found in various classics, it is not enough to know the prescriptions, and it is necessary to have a corresponding level of refining to refine the elixir. Just like another world, many people know how to make an atomic bomb, but how many people can actually make it.

The level of alchemy is slowly improved through continuous practice and research, and it is not something that can be achieved by just mastering knowledge.

For example, Hua Yu could also consult some basic prescriptions from the classics that recorded elixirs, but before systematically studying and refining medicines, it was impossible to refine them successfully according to the prescriptions.

...

"Let's start!" After everything was ready, Yan Tianzhen instructed Hua Yu and Lan Yumeng.

"Yes, real people".

Hearing the real person's password, Hua Yu and Lan Yumeng put all the processed elixirs on the medicine table next to Yan Tianzhen in turn.

Yan Tianzhen spread out his left hand, and a small and delicate jade pool appeared in the palm of his hand, and then the small jade pool became larger and suspended in front of the real person.

This jade pool is Yan Tianzhen's tool for refining medicine, which is both a magic weapon and a spell, similar to Hua Yu's natal spell "Taixu Xuanling Treasure Palace Technique", called "Wanhua Pool". It is a variant of the "Vitality Creation Pool", one of the fundamental spells of the sect.

With a move of her right hand, Yan Tianzhen took out a bunch of elixirs from her storage magic weapon, each of which was covered by a bubble-shaped thing, which should have the effect of protection and isolation.

After Yan Tianzhen took out the elixir, he ordered: "Let the morning rain and dew."

Lan Yumeng took out a jade bottle, and with a finger of his jade hand, some crystal jade dew flew out of the jade bottle, which was the morning dew collected on top of various elixirs in the morning, which was the purest thing to wash the elixir, and was the best at removing the miscellaneous qi contaminated in the elixir.

After the morning rain and dew all converged into the "Wanhua Pool", Yan Tianzhen took out a jade lotus flower that exuded a compelling cold atmosphere from a pile of elixirs, this jade lotus flower is called "Ice Jade Cold Lotus", its nature is cold, it can clear the heart and replenish the mind, enhance cultivation, and only grow in the place where it is yin and cold, it is a very precious elixir.

Yan Tianzhen carefully landed the "Ice Jade Cold Lotus" on the jade liquid in the "Wanhua Pool", and then controlled the Jade Lotus to completely sink into the morning rain and dew.

After that, he took out a fruit that emitted heat from the pile of elixirs, this fruit was the "Burning Sun Fruit" produced by the "Flame Xuanyang Wood", which was yang heat, and if it was used alone, it could quench the true element, wash the marrow and cut the veins.

In the "Heaven Replenishing Yuan Liquid" to be refined today, the two elixirs of "Burning Sun Fruit" and "Ice Jade Cold Lotus" are the main medicines.

Yan Tianzhen put the "Burning Sun Fruit" into the "Wanhua Pool", first kneaded it into juice with spiritual power, and then extracted the washing juice with Yuehua Yulu, Xingchen Essence and other substances, and finally, obtained a blazing fiery red liquid, which kept changing and swimming in the pool.

After reaching this step, Yan Tianzhen said: "The melting of the medicine begins."

Hua Yu and Lan Yumeng hurriedly introduced the five essences of the five elements, such as "Golden Pith Fat", "Leaving the Dust", "Rebirth Liquid", "Rootless Water" and "Ground Inflammation Glue", which had been processed in advance, into the "Wanhua Pool".

Yan Tianzhen urged the "Wanhua Pool", and suddenly the entire pool was shrouded in a light shield composed of light.

With the control of Yan Tianzhen, the "Ice Jade Cold Lotus" emerged from the morning rain and dew, and the fiery red liquid flew above the lotus, constantly circling like a fire dragon, and the five kinds of five elements essence were distributed around the lotus, and they were also rotating around the lotus.

Melting medicine, this step is the most important step in refining medicine, also known as combining medicine, which is the step of fusing various matching elixirs together and finally turning them into medicines.

The fiery red liquid extracted from the "Ice Jade Cold Lotus" and the "Burning Yang Fruit", one yin and one yang, one cold and one hot, is the opposite of yin and yang, as the so-called water and fire are incompatible, it is not easy to melt the two together, plus the other five kinds of essences belonging to the five elements, it is even more difficult to fuse all of these together.

To refine this "Heaven Replenishing Yuan Liquid", it requires not only superb alchemy skills, but also advanced cultivation to do so.

Yan Tianzhen had already put all his energy into the jade pool, and Hua Yu and Lan Yumeng were staring without blinking.

After hovering for a while, the fiery red on the lotus flower seemed to adapt to the cold breath, plunged into the lotus flower, wandering among the lotus, and the petals of the lotus began to slowly close, completely enveloping the fire dragon.

Then, starting with the "Rebirth Liquid", the five essences of the five elements, such as "Rebirth Liquid", "Separation from Dust" and "Golden Pidi", are also continuously integrated into the lotus flower according to the order of the five elements, and the lotus flower becomes a colorful color, and constantly rotates and shines with colorful glow.

Yan Tianzhen also began to become struggling, as if it was not easy to control this colorful lotus, Yan Tianzhen pinched the seal with both hands, recited the mantra mantra, and held it tightly.

In the end, the flickering light of the multicolored lotus flower dissipated, and the multicolored lotus flower also became colorless and transparent, and Yan Tianzhen also stopped.

With a wave of his hand, the real person removed the light shield that shrouded the "Wanhua Pool", stretched out his left hand, and the jade pool became smaller and flew to her palm to levitate, and there was a pool of clear jade liquid in the jade pool, and a crystal clear lotus flower floated in the clear pool of jade liquid.

The real jade pointed a little, and suddenly the petals of the lotus began to open slowly, and there was a small amount of colorful crystal jade liquid in the lotus, and at the moment when the lotus petals opened, a breath full of vitality flew into the noses of several people, and suddenly felt as if the body and soul had been cleansed, and all kinds of dark diseases in the body were cured, and the cultivation was further advanced.

The real person hurriedly closed the lotus petals, while Hua Yu and Lan Yumeng were completely immersed in the beauty of this moment.

The magic of alchemy in real people, the infinite charm of the lotus blossom of the clear pond jade liquid, and the breath emitted by the "Huitian Replenishing Yuan Liquid" full of vitality are all so wonderful.

Sure enough, every kind of knowledge in the cultivation world is so broad and profound, enough for every cultivator to devote his whole life to exploring, and at this moment, Hua Yu was deeply touched.
