Carefully opening the cap, a strong vitality quickly filled the surroundings, and an indescribable forest scent emanated from the bottle, which lifted Sean's spirit.

The bottle is made of wood-rich crystals and shaped using a special alchemy process, and the master's high level of runes and enchantments make the inside of the bottle look mysterious and beautiful to ignore.

If the Elven Fountain is not treated after it is made, the energy and blessings in it will soon dissipate, and within a few years, it will become an ordinary fountain of life.

And this container is specially made by the elves, although the effect is not difficult to achieve, but this is also part of the sincerity of the elves, at least it can make the buyer's face look better.

Sean used his mana to take out a milliliter of the Elven Secret Spring from the bottle and carefully added it to the half-finished potion that had been prepared long ago.

The potion that was already green was originally green, but after this drop of the Spirit Secret Spring was dripped into it, the color instantly became more profound, and the liquid medicine slowly emitted light, becoming brighter little by little.

With the cap closed, Sean turned to face the potion and brandished the staff in his hand and began to cast spells.

"Apprentice Spell - Matter Conversion 31-1920"

"Apprentice Spell - Universal Super Matter Fusion"

After using several spells in a row, Sean completed this alchemy.

After many purifications and changes, the color of the potion has long since changed from dark green to faintly black.

Ever since he got the Fountain of Life from Satuk more than two months ago, Sean has been thinking about how to use it.

It is impossible to take it directly, and Sean does not need it to maintain his youth or prolong his life, Sean has a long-term vision from the beginning, and has never considered using these foreign substances to continue his life.

The process of configuring the combination potion (20) is very complicated, and there will be occasional free times, and Sean will use this time to do some experiments, trying to find a way to integrate the elven secret fountain into the potion to find the most suitable combination.

As mentioned before, the formula of the medicine must indicate the principle and function of all materials, as well as a detailed analysis of the whole process of the change of the drug, otherwise it is not a complete formula.

Thanks to his extraordinary memory and Lauren's rich legacy, Sean didn't think much about the recipe for long, and he had already chosen a potion that would permanently increase his vitality.

Because he was in a hurry before leaving, Sean didn't know if Lauren had destroyed all of his book collection before he was promoted.

But these were all inconsequential trifles, for in eleven years of experimental assistance, Lauren had already given him all his knowledge little by little as a reward for being an assistant.

The spy servant who was placed in the mage's tower naturally did not understand how talented Sean was.

Fortunately, they didn't know, otherwise Sean wouldn't have been loaded into a prisoner cart by the nobleman and given to the kobold, but would have been imprisoned and interrogated little by little to find out all his memories.

However, there is no what if, since Sean has escaped, he will definitely try to gain more power and make that guy named Brent Broad pay.

Placing the newly completed life potion on the side shelf, Sean carefully counted the amounts.

It was an anonymous potion, perhaps due to its premature age, and its main ingredient, Sean, had never heard of it, and Lauren had inadvertently mentioned that it had been obtained by trading with others when he was a young student at a spellcaster's academy called Gorks.

Lauren was unable to make it because of the lack of the main material, but due to the rarity of the effect, he still regarded it as one of his treasured recipes.

According to the description in the recipe and his own experiments, Sean found that the use of the Elven Secret Spring to replace its main ingredient was extremely suitable, and even many times stronger than the original effect!

The characteristics of the auxiliary materials greatly stimulate the power in the Elven Secret Spring, transforming all abilities into an increase in life force.

After many tests, Sean finally researched the most suitable ratio, and invested a lot of money in auxiliary materials to produce many modifications of this nameless potion in batches.

That's 200 bottles! This is all the money he has earned in more than two months, and the free time in exchange, and of course, counting one-fifth of the Elven Secret Spring.

Sean didn't make so many potions for himself, nor for sale, but all of them to strengthen his weapon, the staff of reincarnation.

The Reincarnation Staff is currently a semi-finished product, so its actual value is not high, about tens of thousands of gold coins, which is far from the cost of hundreds of thousands.

But you can't look at the surface of everything, once the staff is completely made, it will be a treasure that is difficult to buy even a million gold coins, a real apprentice-level top staff, so Sean is willing to invest a lot of money and energy in it, even if it temporarily slows down the progress of strength growth.

After being crafted into a staff, both the Silver Devouring Vine and the Mineral-Eating Beast's Spine have great potential for growth, and through the infusion of life and death energy, the staff will continue to grow, making it more and more powerful until it reaches its upper limit.

Death energy is easy to obtain, and when the future goes to the battlefield, it will be a real corpse all over the field, so the only difficulty now is the source of life energy, so Sean will spend a lot of effort to make this potion rich in vitality.

"Two hundred bottles, it should be enough for the time being."

With a twinkle in his eyes, Sean moved out the small ritual circle that had been prepared in advance, and fixed the staff of reincarnation in its center, his purpose was to use this ritual magic to help the staff absorb potions and produce evolution, so as to add another apprentice-level spell.

According to his speculation, with a large supply of life energy, the staff of reincarnation should have enough power to supply a rune of life with magic.

Sean's body was rippling with mana, and the entire two hundred potion bottles stacked on the side were suspended in the air, and with Sean's control, the corks began to fall off one by one.

The green to black potion poured out of the bottle, wrapping the entire staff, and gradually absorbed by the silver devouring vine on the reincarnation staff during the long ritual process, turning it into food for its growth.

When the green light faded, the new look of the staff of reincarnation appeared in front of Sean.

The silver vines were dyed light green, and after this evolution, the appearance of the reincarnation staff became better, and the spine of the mineral-eating beast at the core of the staff had been completely wrapped in the vines that were growing wildly, and it was not exposed at all, just like an ordinary plant staff.
