Chapter 383
In Himan's workshop, Cheng Dalei picked up a piece of blue paper from the medicinal liquid with tweezers.
"What is this paper made of?"
"It is made from a type of water grass harvested from the river, then soaked in a specially prepared medicinal liquid," Himan said. "In this way, it won't fade for a long time."
"Can others replicate this?" Cheng Dalei asked.
"Take a look for yourself."
Himan picked up a piece of air-dried paper and held it up to the sun, and the initially blue paper displayed a dazzling array of colors, as splendid as a rainbow. Cheng Dalei's eyes sparkled; he had never even heard of paper with such characteristics, let alone seen it.
"Is the cost high?" asked Cheng Dalei.
"It's made with the juices of several local plants. The raw materials are locally available, and the formula for the pigment is unique to us."
