"For ordinary spiritual roots, a slight improvement is not very useful. But if your disciple has a Low-Grade Heavenly Spiritual Root, using this Glazed Immortal Crystal will purify it to a Mid-Grade Heavenly Spiritual Root!"

"A High-Grade Heavenly Spiritual Root might even have a chance to be elevated to a Supreme-Grade Heavenly Spiritual Root!"
