Hearing his reply, Wan Yi Jun gave an agreeing nod and turned to the rest of the people.
"Did you see a window in the other cells? But this cell doesn't have a window but a crack is in the exact place where the window used to be." He explained it with a gentle smile.
"So the prisoner escaped through the window?" Bing Wen foolishly asked as he held onto the chain with both hands,
"Yes. the person who was in this cell, tried his best to break the window and the chains together," Wan Yi added as he lend a hand to lift the chain into the cell. As he said, there was a broken piece of a metal window frame was tied on the other end of it,
"See these markings on the wall, it was evident that whoever was tied up in this cell, tried to break the chains by hitting it on the walls." He gathered their attention towards the faded markings on the stone wall.
