"What is oyster cement?" Wang Shouzhe put down his maritime merchant thoughts and asked curiously.

"Oyster cement is a building material made by objects like oysters, shells, and so on, processed by kiln-burning and other methods." Chen Fanghua explained, "Using oyster cement and river sand in a suitable ratio can ensure a good bond between bricks, tiles, and stones, making the stones as solid as a whole. It is often used in the walls of prominent families or government offices. Because it isn't mass-produced, its cost is relatively high. Since you come from a noble lineage, young master Wang, it's completely normal for you to be unfamiliar with this basic building material."

"I see." Wang Shouzhe 'understood suddenly', full of joy, "Reading ten thousand books is no better than traveling ten thousand miles. I did gain some new insights."
