Due to last night's nightmare, she finally stayed up until work. She had already thought about taking this artifact to Uncle Zhang for a while.

The first conversation made Xiao Ai remember deeply, and he always felt that Uncle Zhang would make new discoveries.

When I came to the outside of the store, I saw that Uncle Zhang was busy distributing keys to customers. Xiao Ai didn't want to bother, so he looked at the side. The shop is small and decorated in an antique style, like a small museum with locks.

Unexpectedly, there are so many locks in the world, which completely subverts her perception of locks.

Just as he was looking at the surprise, Uncle Zhang said, "Miss Su, welcome to you, what's the matter?" ”

Xiao Ai hurriedly said: "Uncle Zhang, you have collected so many strange locks!" A lot I've never seen before. ”

Uncle Zhang said: "Every line has a doorway for each line, this lock has a long history, since the Spring and Autumn Period and the Warring States Period, the wisdom of the ancients is unimaginable now." At first it was wooden, and later it was made of iron, copper, silver, and gold. ”

He pointed to the locks in the window and said, "They are not the same shapes, even the keyholes are of different grades. The people of Li use the word "one" hole lock, the scholar doctor uses the word "shi" and "Ji" word hole lock, and the birthday celebration uses the word "longevity" and "happiness" hole lock, and the emperor will have another difference, and he shall not trespass the use, and he will be killed if he uses the wrong one. ”

Xiao Ai listened attentively and nodded incessantly. I feel that the wisdom of ancient Chinese craftsmen is really amazing!

She took out the artifact she studied yesterday and gave it to Uncle Zhang and said, "Uncle Zhang, how can you be sure that it is a key?" What shape is the lock, and what is such a strange lock used for? "Xiao Ai's series of questions are like shooting a machine gun.

Uncle Zhang didn't know where to start for a while, so he poured a cup of tea and gave it to Xiao Ai: "It's strange to say, since I changed my cornea, I feel that I can better recognize some antiquities." And there is a special interest in antiquities. You did it first that day, or I would have bought it. ”

When Xiao Ai heard this, she felt that this phenomenon was the same as hers, and she also got some unexplained things because of other people's donated organs. So, she must be so strange now that it comes from donors. When she finds out about the artifact, she must check the donor carefully to solve the puzzle.

Xiao Ai hurriedly informed him of last night's discovery, which made Uncle Zhang very excited.

He looked at it carefully and said, "If you look at the design of these groove lines, there must be a convex groove key." Two round keys, two to insert the set, small touch, open the mechanism, the five petals open automatically, it is estimated that the convex groove key also has five petals. Xiao Ai nodded, and Uncle Zhang said again: "The words on it must be related to locks, but I don't recognize these words." ”

Xiao Ai said: "I also guessed that it might be gold, wood, water, fire and earth."

"In this case, it has something to do with the gossip of the five elements," Uncle Zhang muttered.

Xiao Ai frowned and thought: If it is really like what he said, then where is the other half? So what exactly is this lock? It's really more and more unknown. ”
