It was an exceptionally big coffin. Coffins of the old days were often made into sizes of 1×2×3, 2×3×4, 3×4×5, or 4×5×6, but this was an "all six", which meant it had a 6-cun[1] thick lid, 6-cun thick sideboards, as well as a bottom board of the same thickness.
It was made from cedarwood and manchineel wood. The sturdiness of the two types of wood ensured the coffin's impeccable condition.
Bai Yunsheng and the other two could not see through the boards and had to ask Gu Yu, "Is this the real one?"
"There is indeed a body inside. We'll know after we open it."
Gu Yu put an open palm on the edge of the coffin and exerted a gentle force, which shook the boards of the coffin loose. He then gave it a little push. With a "clank", the boards fell apart.
"..."
You Yu was a little afraid and turned his eyes away from the coffin. A moment later, he realized that instead of the putrid smell he was anticipating, there was instead a faint fragrance of medicinal herbs.
