[Eon's POV: ]
Miss Mia started with the stone and then finished the harmonic mixture of high-purity acids and other supporting chemicals. She then went ahead and used the artifacts of Primary and Secondary 'divisional' reactions on them independently before getting on to create her own unique alchemy magic circle.
'People were excited when they saw the unique magic circle that not only contained the formulas to encode certain features but also decode some certain ones that the caster wanted. Their reaction to this self-made alchemy circle was so powerful that the whole of the stadium from the inside and the outside was filled with cheers and applause.'
The major reason the general public applauded was mostly thanks to the great commentary of the announcer who was explaining everything to them in simple terms however, the other reason was how she had created the attractive magic circle.
