Zhang Yan noticed something peculiar in Yin Zhishou's tone and asked, "Is there something wrong with this vessel?"
Yin Zhishou shook his head with a bitter smile and said, "Let me have someone fetch the blueprint. You'll understand once you see it, fellow Daoist."
He gave some whispered instructions to a nearby servant. The servant promptly left and, after about as long as it takes to drink a cup of tea, returned carrying a rolled-up blueprint and a black box.
Yin Zhishou reached out to take them. He carefully placed the black box on the table and then unrolled the blueprint in front of Zhang Yan. Infusing it with a trace of Spiritual Energy, he said, "Fellow Daoist, take a look. This blueprint details the dimensions of the sea boat, the materials used in its construction, the number of prohibitions set upon it, and the layout of its various levels—it's all clearly illustrated."
The blueprint, activated by his Spiritual Energy, immediately projected a radiant image into the air.
