Moonwell Water was a special holy water from the Moonwells near the Elven Mother Tree.
The Moonwell was a special structure of the Elf Race, a sacred creation they had developed through the Elven Mother Tree and their research into runic power.
It could produce Moonwell Water only near the Mother Tree of Life.
Moreover, each Moonwell could produce water only beneath the moonlight at night, placing severe limits on its production time.
Fortunately, many Moonwells could be built around the Elven Mother Tree, allowing a continuous supply and even a certain surplus.
But its shelf life was less than a day.
Anyone who wanted to use this Moonwell Water could therefore only come to the Elf Race's trading Dungeon Space at Base No. 10.
It could not be taken elsewhere as merchandise at all.
A secondary Elven Mother Tree existed in this Dungeon Space, along with Moonwells, which was why Moonwell Water was available for sale here.
The sale of Moonwell Water here was also the result of negotiations between humanity's higher-ups and the Elf Race.
Under normal circumstances, they would never sell this holy water of their race.
With its special life and moonlight properties, Moonwell Water was extremely expensive. Jiang Ziliu bought less than 100 milliliters, yet it cost him nearly sixty million yuan's worth of Elemental Crystals.
Even so, this was a fair price.
The relatively peace-loving Elf Race, which revered nature and sincerity, rarely considered raising prices for profit.
After obtaining the Moonwell Water, Jiang Ziliu spent one D-grade Elemental Crystal to rent a treehouse in this Dungeon Space, which he could use for only three days.
In trade with other races, Elemental Crystals were the only hard currency that could be used.
Alternatively, precious medicinal herbs and special materials that retained their value could be used.
Ordinary human currency could not be used here!
Next, Jiang Ziliu stayed in his rented little house and began preparing the potion the Green-Skinned Shapeshifting Spirit needed to evolve.
Human pharmacists had their own ranks. By those standards, Jiang Ziliu's pharmaceutical skills placed him roughly at the peak of Silver, or even at Quasi-Gold Rank.
As he continued learning, preparing potions had already become a very basic skill for him.
His main achievement had already advanced to the point of devising potion formulas that could allow a tamed beast to evolve.
Every tamed beast had its own particular circumstances.
Thus, different tamed beasts required completely different evolution potions, just as prescriptions needed to be adjusted for human patients with different constitutions and conditions.
Without support from Probability Judgment, the potion formulas Jiang Ziliu prepared could give a tamed beast a minimum evolution probability of 65%.
Meanwhile, formulas devised by ordinary Gold Rank pharmacists could achieve an evolution probability of only 70% at most.
This time, he had invested heavily, spending nearly 150 million yuan on potion ingredients before successfully preparing the Green-Skinned Shapeshifting Spirit's potion.
The cost was so high because this time he needed the Green-Skinned Shapeshifting Spirit to evolve in a specific direction and develop a healing skill.
If he merely wanted it to evolve without directing its evolution, the cost might not even have reached five hundred thousand yuan.
One small, specified goal could increase both the difficulty of preparing the potion and the required grade of its ingredients by dozens of times or more.
The potion preparation went smoothly.
But this evolution potion was a thick green liquid, rather than the gel-like potions he had prepared before.
Its method of use was also very simple!
Drink it!
After preparing the potion, he summoned the Green-Skinned Shapeshifting Spirit.
True to its nature as a highly intelligent tamed beast, the Green-Skinned Shapeshifting Spirit saw the potion in Jiang Ziliu's hand the moment it appeared, and its instincts told it that the potion would benefit it enormously.
The potion held an immense attraction for it.
Rather than pouncing straight at it, the little fellow conveyed its intense desire to its beast tamer.
Jiang Ziliu did not delay either. He slowly fed it to the little fellow, then finally gave it a drop of Stalactite Vein Milk to swallow.
Used this way, the Stalactite Vein Milk could supply the energy the little fellow needed during its evolution.
After drinking it, the Green-Skinned Shapeshifting Spirit fell into a deep sleep.
Evolution through sleep was a common method of evolution among exotic beasts.
Jiang Ziliu recalled it into his Beast-Taming Space, then continued handling his next tasks.
He took out the Soul-Cleansing Mushroom he had obtained and, together with a low-grade Soul Crystal, began preparing a potion to strengthen his soul.
This time, he did not intend to waste time and wanted to give himself a decent improvement as well.
After using high-grade ingredients such as the Soul-Cleansing Mushroom and Soul Crystal, Jiang Ziliu also added the remaining Moonwell Water so that the entire potion's medicinal effects would take hold more gently.
In the end, he prepared a soul-strengthening potion in pill form.
Taking one such pill would allow his soul strength to increase slowly and steadily over the following month.
The soul was a human's core. Forcibly strengthening it by a large amount within a short time was not a good thing and could not be done frequently.
To address this issue, he made improvements during this potion preparation.
He made the soul potion's strengthening effect gentler and slower, achieving the goal of gradually improving the soul without leaving hidden dangers.
This time, Jiang Ziliu prepared five of these soul-strengthening pills in total, enough to strengthen his soul for the next five months!
After successfully preparing them, he used Probability Judgment to assess them.
"What is the probability of this potion causing potential risks during the soul-strengthening process?"
The answer soon appeared: 0.21%!
This figure was extremely low, with less than a one-in-five-hundred chance of a problem occurring.
But in pharmaceuticals, a figure of 100% was impossible. Potions always carried some medicinal toxicity and some risk.
This ratio was already extraordinarily low. Even many higher-ranked Diamond Rank pharmacists struggled to reduce their potions' risks below 3%!
Jiang Ziliu's ability to keep the risk at 0.21% was also the result of support from Probability Judgment.
After preparing the pills, he swallowed one without hesitation, then placed the remaining four in a jade bottle and tucked it into his spatial orb.
Jade could be used to preserve the medicinal effects of many potions.
He felt no obvious improvement in his soul, only that his mind was exceptionally clear and all his fatigue had vanished.
This was the result of the soul potion releasing its effects slowly.
By the time he finished this step, the Green-Skinned Shapeshifting Spirit had completed its evolution.
Jiang Ziliu summoned it and discovered that its appearance had not changed much, but it possessed a more intelligent spark.
He then opened the information panel and saw the Green-Skinned Shapeshifting Spirit's information.
Green-Skinned Shapeshifting Spirit: Flesh Shapeshifting (SS), Transform into a Plant (C+), Transform into an Animal (C+), Super Digestion (C), Light of Jade (D+).
The Green-Skinned Shapeshifting Spirit had completed its evolution!
Its Flesh Shapeshifting skill was too high-ranked to change, but all its other skills had improved slightly!
Most importantly, it had developed the healing skill Jiang Ziliu wanted most: the D-grade Light of Jade.
When this skill was activated, the Green-Skinned Shapeshifting Spirit could summon a ray of jade light and send it toward a target, using life energy to heal the target's injuries. It even had a slight ability to dispel toxins and negative effects, though this was extremely minor.
It now had healing abilities, and the extremely weak abilities to dispel toxins and negative effects were also very important.
Although their contribution to the overall Light of Jade skill was small, they were indeed present.
As long as he specifically strengthened and improved Light of Jade in the future, these two abilities could also improve to a usable level, or even potentially turn into powerful abilities.
It could be said that this time, the Green-Skinned Shapeshifting Spirit had not only evolved the healing ability Jiang Ziliu needed most, but one that was also highly comprehensive and possessed tremendous growth potential.
Light of Jade could heal not only other targets but also the Green-Skinned Shapeshifting Spirit itself.
This successful evolution filled the healer role in Jiang Ziliu's team of tamed beasts, making the entire team more well-rounded and efficient.
Moreover, this successful evolution also raised the Green-Skinned Shapeshifting Spirit from Nine-Star Gray Rock Rank to Three-Star Black Iron Grade, greatly strengthening its level of life.
The life feedback it produced also let Jiang Ziliu cover the final small stretch of growth at five-star Black Iron Grade, successfully advancing him to a Six-Star Black Iron Grade beast tamer!
