After a moment of silence, Liu Yu calmed down his ups and downs.

With a wave of his hand, dozens of jade boxes appeared around him, containing thirty-three types of spiritual herbs containing Canglang Spiritual Water.

Then he took out dozens of jade bottles and placed them beside him.

To prepare the spiritual water, what is needed is the essence and medicinal power of the spiritual grass and elixir itself. As for the unnecessary medicinal properties and impurities, all unnecessary medicinal properties and impurities need to be removed.

In this first step, the essence and medicinal power are extracted.

The jade bottle made of spiritual jade can well preserve the potency of medicine and prolong the effective time of medicine and the passage of spiritual power. It is best used to preserve the essence.

Gather your energy and concentrate your mind, hold your essence and keep it together.

Liu Yu adjusted her state, and after getting ready, she waved her hand and gently landed the Xuanhuang Cauldron, the ultimate alchemy furnace weapon, in front of her.

Afterwards, he palmed his hands, and the foundation-building true fire emerged from his palms, fell to the fire door of the Xuanhuang Cauldron, and began to preheat the alchemy furnace.

The orange flame burned slowly, growing from small to large, and at the same time, the temperature of the alchemy room also gradually increased.

After a quarter of an hour, the fire door turned reddish and the preheating preparation was almost complete.

Through spiritual observation and spiritual induction, Liu Yu relied on experience to judge that the time was right, so he no longer hesitated.

He stretched out his hand and pointed, and the Xinglan Fruit floated up from the jade box and floated towards the Xuanhuang Cauldron. With a thought, he controlled the lid of the cauldron to rise and fall again after the elixir entered it.

After the Xinglan Fruit entered, Liu Yu's technique changed, and the speed of pinching was only a few minutes faster.

At the same time, the foundation-building true fire in the fire gate suddenly rose, burning more violently, and the firepower became a little more intense.

Under the hot temperatures, the star berries began to show signs of melting.

Liu Yu's eyes were as calm as water, and he controlled the process calmly.

He had already done this kind of thing like refining the essence of elixirs thousands of times, and he was already familiar with it. At this time, he didn't have any panic or impatience.

He skillfully controls the Xuanhuang Cauldron to perform various operations, and his consciousness is always observing every change in the elixir.

Sometimes the fire power is increased, sometimes the fire power is reduced, sometimes the fire is warm and simmered, and sometimes the fire is burned.

With his powerful spiritual consciousness, Liu Yu carefully controlled the changes in the elixir and accurately adjusted the size of the flame.

More than a quarter of an hour later, he suddenly raised his arm.

A gap appeared in the black and yellow cauldron cover, and it quickly fell down. A fruit core fell into the jade box that previously contained the Xinglan fruit.

This is the core of the Xinglan Fruit, which is equivalent to the seed of the Dark Star Spirit Tree.

With this fruit core, Liu Yu can use the Immortal Mansion to spawn the Dark Star Spirit Tree, thereby continuously obtaining the main medicine Xinglan Fruit.

The appearance of the core means that the Xinglan fruit in the cauldron has been completely refined. The next step is to extract the essence of the elixir and separate impurities and unnecessary medicinal properties.

Liu Yu's expression remained unchanged, and his spiritual consciousness always controlled the furnace, flames, and elixir, purifying, refining, and separating them in an orderly manner, carefully controlling every detail.

The sunlight shifted slightly, and another quarter of an hour passed.

The speed of pinching the spell in his hand gradually slowed down, and the purification of Xinglan Fruit was about to be completed, but Liu Yu's expression remained unchanged. This consumption was nothing to a foundation-building monk.

Suddenly, the magic formula in his hand changed again, and the black and yellow cauldron lid opened wide.

A long and thin "water stream" flew out from the cauldron.

This "water flow" is as blue as the blue sky, dotted with sparkling silver lights everywhere, like a vast galaxy, flowing from the sky, accompanied by a rich fragrance and aura.

The "water flow" falls directly towards the jade bottle, accurately falling into the bottle through the mouth of the bottle, without any waste.

It wasn't until the bottle was corked that the strong fragrance slowly faded away.

In the Xuanhuang Cauldron, there was only a lump of gray mixed with blue liquid, which was a combination of impurities and unnecessary medicinal properties.

Liu Yu stood up, cleaned out the liquid, and used the spiritual spring taken from the ancient well of Xianfu to carefully clean the inside of the Xuanhuang Cauldron.

Then, start processing the next spiritual grass.

It took nearly two quarters of an hour to purify the Xinglan fruit. This is because the fruit is the main medicine of Canglang Lingshui, which is of the highest grade and has special properties. In addition, part of the medicinal properties need to be separated.

The remaining spiritual herbs and elixirs are not as good as Xinglan Guo in terms of grade and age. The requirements for purification are not as high, and there is no need to separate the medicinal properties, so the speed will be faster.

Preheating, refining, purifying, cleaning the alchemy furnace

The cycle goes on and on like this, and the five hours pass quickly.

As the final Biyoucao essence is extracted, the process of refining the elixir essence is officially completed.

Using mana to dry the sweat on his forehead, Liu Yuan nodded slightly as he looked at the thirty-three jade bottles containing the essence of elixirs in front of him.

Then he put away the Xuanhuang Cauldron without hesitation and began to prepare the spiritual water.

He took out an emerald green, specially refined large jade bowl and placed it on a wooden table.

Liu Yu added the elixir essences one by one into the jade bowl according to the description on the formula. The order and proportion were all in accordance with the formula.

There was no "genius" idea to modify the formula or improve Canglang Lingshui suddenly.

As the elixir essences were added one by one, the essences of various colors in the jade bowl began to merge, gradually creating a chain reaction.

"Puff"

From time to time, bubbles expand and explode, making a sound like boiling hot water, as if it is about to explode at any time.

There was no fluctuation in Liu Yu's eyes, and she followed the steps on the formula. After the bowl calmed down a little, she continued to add the elixir essence into it.

"Zi Zi"

Like high-concentration sulfuric acid dripping on the skin, the jade bowl made a corrosive sound again, as if it was about to corrode and penetrate the jade bowl.

However, this jade bowl was specially made to cope with this situation, so Liu Yu did not need to worry about it.

At this time, the jade bowl is full of colors, just like the pigments in a large dye vat. The various colors are mixed together, and there is a "strange" smell, which tends to eventually turn them into gray.

From time to time, there are bubbles rolling in it, and green smoke rises. Where is the slightest trace of spiritual water?

"Could it be a scam from beginning to end?"

"Is the formula of Canglang Spiritual Water real or fake?"

Seeing this appearance, Liu Yu could not help but feel a little suspicious.

However, the final configuration was not completed yet, so he temporarily suppressed his inner doubts and continued with the configuration.

I waited quietly for half an hour, watching the essence of the elixir in the jade bowl change naturally.

Seeing that the time was almost up, Liu Yu picked up the last jade bottle containing Xinglan fruit essence, uncorked the bottle, pointed the mouth of the bottle at the jade bowl, and poured out all the elixir essence inside.

The azure blue liquid with silvery light sank directly into the half-gray liquid in the jade bowl without making any sound.

The addition of Xinglan fruit essence has immediate effects.

Suddenly, all the reactions such as rolling, bubbles, and green smoke disappeared instantly, and all the liquid in the jade bowl became "quiet".

Liu Yu opened his eyes wide and carefully observed all this happening, feeling a little curious.

At the same time, he held the thick earth sky umbrella in his hand and kept it in a semi-excited state. If the situation went wrong and a violent reaction occurred, he could protect himself in a single thought.

At this moment, the situation in the jade bowl changed.

With the addition of Xinglan Fruit Essence, the tendency of all Spirit Grass Essences to turn gray slowly stopped, and instead gradually became dyed with a layer of blue, as if they were soaked in blue liquid.

This change happens slowly and steadily, and as time goes by, there are more and more blue colors.

A quarter of an hour later, all the liquid had been assimilated into a blue color, with sparkling silver light in it, just like the light of stars.

At the same time, the "strange" smell has disappeared, and instead a rich fragrance has begun to permeate the air, just like the original fragrance of Xinglan fruit essence.

"Is this Canglang Spiritual Water?"

Liu Yu witnessed all the changes, but couldn't understand the rationale.

But according to the formula, this is "Canglang Lingshui".

However, he does not need to understand the principle behind it at the moment, as long as the effect of Canglang Spiritual Water is exactly as stated in the formula.

Take out two new jade bottles and pour the blue liquid in the jade bowls into the two jade bottles respectively, filling each one to the full.

This much weight is enough for three people.

With Liu Yu's always cautious character, he naturally had no idea of ​​taking it directly.

Let’s not talk about whether Qingsong, an old thief, tampered with the formula. Let’s assume that he didn’t tamper with the formula. Liu Yu wouldn’t believe it all.

Not every former monk has good intentions towards those who come after him.

What some ancient monks left behind was not a legacy, but pits and traps that harmed the lives of later monks.

For example, there are some demonic monks who harbor deep malice towards the world before they die.

They will deliberately arrange the cave to look like the inheritance left by the righteous monks, and then spread the location of the cave through maps, jade slips, etc., attracting some monks who like "adventure" and "novelty hunting" to come.

In fact, there are many traps in the cave, with murderous intentions at every step, trapping the lives of later monks in order to vent their resentment for not achieving immortality.

Even if there are monks with strong strength, good luck, and spending a huge price to pass through many levels, they will still get nothing. In the end, they can only draw water from a bamboo basket and accept the reality of heavy losses.

The "Summary of Demonic Cultivation" records a kind of "fishing law enforcement", which involves setting traps to look like ancient caves, and then spreading the news to attract monks to come to explore and hunt for treasures, and then calmly harvest and absorb resources.

Demonic monks have regrets and resentments before they die, so why don’t righteous monks do the same?
