Unequivocal, irrefutable, verifiable proof!
There was no greater evidence than the Alchemic Stars of Mortal Spirituality for an Alchemist's skills, proven and accepted by the grand Alchemic Dao! It spoke volumes, revealing that an alchemist has sufficient knowledge, skill, and ability to concoct alchemical products in the ninth-grade without any outside or external assistance.
"You!" San Luoyang was uncharacteristically tongue-tied, unimaginably vexed by the situation. Suddenly, within his eyes, seven colorful stars manifested in each, mirroring Wei Wuyin's Alchemic Stars!
He, too, had attained the Alchemic Dao's approval, granted a higher Will towards the way of alchemy.
