Once the old man checked every herb, he nodded to himself. "Everything is in order. You two, follow me."
The old man went to the corner of the hut and made a sequence of hand seals. In a instant, the walls moved and a passage leading to a row of stairs was revealed.
Seeing the old man walking down the stairs, Thomas and Nana exchanged glances before following right after him.
It was a long row of stairs, an unknown amount time had passed before a ten square meters room filled with inscriptions stood before them.
The old man then stepped into a small circle in the middle of the room. Turning back to face the two visitors, he smiled. "Come on in to this old man's alchemy room. I will be starting soon, so feel free to sit down anywhere."
For a moment Thomas thought the system had translated wrongly as he asked. "Alchemy Room?"
"Yes, this old man happens to have some achievement in both inscriptions and alchemy thought the right title would be Pill Refiner since my knowledge of alchemy is only centered on herbology and the art of refining pills."
Thomas and Nana sat in the ground and watched as the the Sage pulled out a jet black object with size of a small water basin.
So this is a pill furnace. The corner of Thomas' lips raised. Surely, it looked pretty similar to the depictions of the ones used in fantasy movies and shows, only it's size was quite small though.
The only thing to which he was confused was that as the old man is most definitely a demon, he shouldn't be able to perform alchemy. In the inherited memories of the demons there was a little information about alchemy and it goes this way;
1: The size of a pill furnace didn't matter much as long the one performing the alchemy doesn't plan on producing a high amount of pills or if it is an Alchemy Cauldron for brewing potions.
2: Pill Refining the refining simply done through the use of a highly positive source of energy to purify all the contents of the furnace into a medicinal liquid that would then be condensed it a pill with the use of a set of spirit-based runes called inscriptions.
3: Potions in the other hand were brewed without the use of inscriptions, would need a big cauldron and instead of just herbs, it would use other thing such as Jetbat's Wing, Phoenix Tail, Dragon Blood and many others. Because of its highly energetic and unstable state, it would remain in a liquid form which the alchemist would pour into a special bottle made to contain all the medicinal potency.
For a highly experienced expert of the Demon Race, it wasn't hard for him to recall the formula to a pill he hadn't refined in centuries.
The Old Sage then organized the herbs in order of use and placed them by his side; turning to the furnace again, he formed a series of hand seals and then began pouring his large amount of silver mist.
As the furnace greedily absorbed all of the energy, countless thin runes in the interior of the furnace lit up forming an perfect formation.
Soon, a pale yellow flame was born in it's center.
It seems since the old man as a demon didn't possess a positive energy to perform alchemy, he relied on this thin formation to produce this highly positive flame. Even Thomas who only knew a little about alchemy
Orderly placing the 3rd and 4rd herbs Nana collected into the pill furnace, the old Sage then began pouring his demon into it, using the Yellowstone Flame in his furnace to refine these herbs and extract their medicinal essence.
As the all the 3rd and 4rd grade herbs were refined into medicinal liquid under the shimmering yellow flames.
Soon a total of eight drops of the pure herbal began merging together and undergoing miraculous changes.
Little by little the drops melted into each other. It was a slow process and with each pair of drops merging, a milky white light would illuminate the whole room that was filled with a pure herbal scent.
Nana sniffed before yawing, for some reason this scent made her feel very warm and comfortable. All it took was a couple minutes feeling this scent and she was already in deep sleep. On the other way, Thomas felt the exact opposite.
All his pores glowed and his blood burned as this scent was absorbed into his body. Immediately he felt this scent was very beneficial to him to the point his own physique showed signs of leveling up once more.
Once a long time has passed, the old man who kept his eyes shut the entire time finally acted. His hands rapidly moving draw multiple lines in the air, each motion was perfectly calculated and with a grace Thomas had never seen before.
All the few drops that remained was the essence of the essence and once these inscription were drawled in the air, they were immediately attracted to it.
