"There are two essential tools for a painter, one is the immortal paper, and the other is the immortal brush. At that time, he had already attained immortality. Brushes capable of being used by immortals were rare in this world, and even the raw materials for manufacturing such brushes were lacking. Without materials, even the Yingtian Immortal couldn't make one."
"For the immortal paper, he was not so worried, for he could create such paper from wood shavings he took from himself. But the brush, that was difficult."
"The nearest material for the brush was our hair, probably because we all belong to the human race. Our hair couldn't be used to create an immortal brush, so his attention was focused on the Qilin Immortal."
"A clump of fur from the tail of the Qilin Immortal is suitable for making an immortal brush."
