Dalia's lab was not too big but was well equipped with most of the items one would need for alchemy. Dalia was very picky with her tools so every alchemy tools here were the best of the best. So Elena did not need to take out any other equipment to start the alchemy process.
First Elena took out a total of 10 Forest Dragon's Leaf and then she washed them with spirit spring water. Spirit spring water was special as they also contained natural energy and were the best things to handle Forest Dragon's Leaves.
Then she left the leaves to dry out while taking out a fruit called Ouran and a berry called the Jokaberries. They were all quite rare items but nowhere near as rare as the Forest Dragon's Leaf.
Elena handled those items like an expert and everyone watched her while holding the breath. She first pinched the berries to extract juice from it and then put the Ouran fruit in the juice.
