The bed boards were made up of smoothly polished ivory boards pieced together, with hardly any gaps visible between them.
Lin Shuo instructed the soldiers to pry open those ivory boards one by one while he carefully observed and explored the wall near the bed.
Soon, he noticed a small protrusion. He pressed down on it firmly, and a hidden door appeared on the wall.
He was just about to have torches prepared to go inside when a soldier who was prying open the ivory boards shouted, "There's something here!"
Lin Shuo went over to take a look. Beneath the ivory boards was a gap containing many letters, neatly tied in bundles.
He had the soldiers keep an eye on this spot and personally handed the letters over to the Duke before leading a team with torches into the hidden door.
