《太平广记·卷十三·神仙十三》
两个人相视一笑，就拿出一个玉石匣子中的本子翻看，见上面果然有仙公武丁的名字，于是就给了他两枚药丸让他吃下去。
二人相向而笑，遂出玉函，看素书，果有武丁姓名，于是与药二丸，令服之。
The two looked at each other and smiled, then took out a book from a jade box and flipped through it. They saw the name of the immortal, Wu Ding, on it, so they gave him two pills and told him to swallow them.
