Liu Yu's spiritual sense penetrated into the cauldron, carefully regulating the size and temperature of the flame, removing impurities and refining the essence of the spiritual medicine.

According to the pill recipe, get familiar with the process of alchemy step by step.

For a period of time, he kept pinching the magic tricks and putting spiritual medicines into them according to the requirements of the Spirit Gathering Pill recipe.

Fuse the essence of the elixir extracted from the cauldron into a circle the size of marbles to start condense the pill.

As time passed little by little, strands of medicinal fragrance gradually spread out from the small tripod, which made people feel refreshed.

Liu Yu's forehead was sweating, but his face showed expectation, and he felt a little excited.

The next moment, his magic trick changed, and a red light appeared on the magic circle, and the flame slowly extinguished.

The spiritual consciousness moved and controlled the cauldron to fly up.

At this time, the rich aroma of medicine gradually faded, and a strange smell filled the air.

"Could it be?"

Liu Yu's face changed, as if he had thought of something, so he hurriedly stepped forward and took a look.

I saw a few mottled elixirs lying on the bottom of the cauldron, which was very different from the spirit-gathering pills I saw on weekdays.

"Shi Dan?"

Liu Yu's face turned dark, feeling a little regretful, but it was natural.

After all, this is the first time he has refining. He is not a genius in alchemy, but he has a little advantage over ordinary monks.

The so-called secondary elixir is a product of failure in alchemy.

It is caused by the error in the heat or the timing of the furnace opening and most of the loss of medicine. The spiritual power contained in this type of secondary pill is extremely small and its effect is minimal.

Smiling bitterly, Liu Yu calmed down and put away the second pill at will.

Pour out the impurity powder in the cauldron, then clean it with clean water, and then start refining the alchemy again after the copper cauldron has completely cooled down.
