The medicinal properties of the source plant are in the source plant, and the source plant needs to be burned into a liquid state first.
It sounds so simple.
This is a source plant at the level of a mythical beast.
It is difficult to burn it into a liquid state.
When the temperature is high, the source plants will be burned to ashes.
If the temperature is low, the medicinal properties of the source plant will be lost in vain, and the medicinal liquid will not be quenched.
The temperature should be just right.
To refine an elixir, a large number of sources are needed.
In an alchemy furnace, these source plants must be put in.
In the end, all the medicinal liquids must be integrated at the moment when all the source plants are tempered.
Why temper together?
Because the medicinal properties will be lost.
If the medicinal solution is taken out, the temperature will become lower and the medicinal properties will be lost immediately.
Once it becomes a solid state and the liquid medicine is melted, most of its medicinal properties will be lost.
And many of these medicinal properties will become impurities.
This source plant will be useless.
Even if you put it back into the alchemy furnace, the medicine is either not powerful enough.
Either there are too many impurities and it needs to be tempered again.
What if it is not taken out but placed in the alchemy furnace to maintain a good temperature?
Nope either.
Even if the temperature remains unchanged, the medicinal properties will slowly be lost, but the loss rate will be slower.
At the same time, the liquid medicine will not turn into impurities during the loss process.
Once the loss of medicinal properties of the medicinal solution reaches a critical point, the medicinal solution will also become impurities and become unusable.
Therefore, it is impossible for an alchemist to refine the source plants one by one.
They must be tempered together.
Moreover, many source plants have complex reactions, and it is necessary to temper other source plants first, and then use the medicinal properties of other source plants to refine it.
That's right, it's not tempered by flames, but by the medicinal properties of other plants.
This is very complicated, and it is very difficult for an alchemist to achieve perfection.
This is why perfect quality is so difficult to refine.
This is also why the alchemist will be mentally exhausted after refining a batch of elixirs.
Of course it will be consumed!
Because the alchemist needs to concentrate.
Because the alchemist needs to control the temperature in the alchemy furnace to be different.
Each source plant requires a different temperature, so the alchemist must isolate the source plants and concentrate on refining.
This tests the alchemist's ability.
The Nether Fire can help him temper every source plant as quickly as possible.
It can be done in an instant.
Even if the same source plant requires the same temperature, he can use the ghost fire to refine the two source plants at the same time and temper them together.
In this case, even a hundred species of source plants would only take a quarter of an hour to be tempered.
In a quarter of an hour, even the first tempered source plant will not lose its medicinal properties or become impurities.
Then he could fuse these medicinal liquids however he wanted.
His control over the ghost fire has reached the point where he can wave his fingers like an arm, which is far beyond what the earth fire can match.
Ordinary alchemists use earth fire, no matter how good the earth fire is, it is impossible to achieve the effect he has.
After all, it is an external force.
The ground fire can be very stable, which is already very good.
The temperature of some earth fire flames is unstable, sometimes high and sometimes low, making it impossible to refine elixirs.
Even if you find a ground fire with a stable temperature, it will be useless. It is not your own power and cannot be controlled.
However, a half-step Supreme Realm expert who has understood the rules of fire can use his own flames to refine divine beast-level pills without relying on earthly fire.
