At dinner, the eldest aunt came to mix another meal, and when she didn't see Zhou Yingqiang, she said a lot of good things, and then led her niece home.

On the fifth day of the first lunar month, the bored Qingping followed her grandfather into the cave opened on the mountain next to the backyard to store artichokes.

On the innermost side of the cave, there are several bundles of sagebrush piled up, and after moving away, there is a small wooden door that can accommodate a person to enter and exit.

The wooden door enters a cave that is wider than the outside, and the grooves dug into the three walls are inlaid with wooden boards, resembling layers of bookshelves, on which are placed yellowed paper, thread-bound books.

Qingping used to love to read those ancient books such as romance on the wall on the left, the text is not exactly ancient Chinese, easy to understand and the story is interesting.

On the right side, there are books similar to Tang poems and Song Ci, and I heard my grandfather say that they are all his manuscripts, but the previous Qingping was not interested.

There are not many books on the innermost shelf, and they are still some historical records and other books, so Qingping has never turned them.

Grandpa took her to the innermost bookshelf today and asked her to flip through the books.

A traditional Classic of Mountains and Seas, a set of Siku Quanshu, a historical record, and a set of twenty-four histories, all of which are handwritten, the more Qingping rolls her eyes, the brighter it becomes, because she has seen the fonts on these books, and she has seen it in Qin Lao.

When she flipped through all the books, she saw a box similar to the 'gold brick' in Li Changxun's hand in the upper right corner of the top layer.

However, the whole body of this box is jet black, and this box is only half the size of the 'gold brick', perhaps because my grandfather often comes to wipe it, and the jet black is also shiny and shiny.

Qingping took it down, put it on the simple table in the middle of the cave that was propped up for reading, and carefully turned it on with a kerosene lamp.

There was a pair of words in the box, and the place where the words were signed turned out to be Qin Yefeng's seal.

Qingping closed the box carefully, and then tiptoed to put it back in its original position, but when she put it up, she saw a wooden knob on the wooden wall where the box was located.

Remembering the look on her grandfather's face when he sent her in and insisted on her reading the book on this wall, she felt that her grandfather seemed to have something to say to her.

Qingping put the box back on the table, and then turned the knob with her hand, and the bookshelf on the back wall actually moved, opening a passage that could only be passed through by one person.

Qingping took the kerosene lamp and got in.

There is not much space inside, and there is a platform dug into the opposite wall, on which is placed a box that is about sixty centimeters long, about fifty high, and about forty centimeters wide.

The eight legs of the box were inlaid with shiny 'gold plates', and the lock was also gold, but the lock hung was a large brass lock.

Qingping approached the box excitedly, holding the old-fashioned big copper lock, how much she wished that the lock was open, because except for a small accident, this box was exactly the same shape as the box that Kang Yonglu and the three of them dug up in her yard.

The big copper lock was locked, Qingping looked around on the platform, and also groped around the nearby wall, but did not find the key.

Qingping touched the box regretfully, turned around and walked out, and then returned the bookshelf to its original place.

Walked out of the cave and hurried to the door of the hall, but Qingping hesitated.

If this box is real, then Grandpa is afraid that he wants to tell her about her background today, but does she really want to know her background experience? The box looks too simple.
