Xiao Ai patiently patrols the flea market, and now she has a soft spot for antiques.

Although she couldn't explain such a huge change in her hobbies after being discharged from the hospital, it was this passion that prompted her to look for treasures.

There are all kinds of antiques on the stalls. It is really difficult for people without eyesight to distinguish the authenticity of treasures.

Suddenly, on a stall, I saw a metal cylinder about two inches long, one end was smooth, and the other end seemed to have five petals. The whole body is jet black, and there are obvious grooves on the barrel body. Xiao Ai figured out in his heart that this groove resembled a figure and a text, and it was difficult to distinguish for a while, but he liked it very much.

The weight is not heavy, but it is not clear what kind of metal it is made of. I was wondering which dynasty it was.

Suddenly, I heard someone beside me: "This utensil is so special!" Girl, can you let me appreciate it? ”

Xiao Ai turned his head to see an old man in his early 50s, wearing a pair of reading glasses and a begging gaze.

She said, "I'll show you." ”

The middle-aged man held the utensils in his hand, took out a magnifying glass, looked left and right, and looked very professional. He muttered, "It's so weird, it's rare in history."

Xiao Ai said curiously: "Uncle, what is the mystery of discovering......?"

The uncle sighed, "I'm not sure for a while." It may be a key, it is estimated that this is a yin and yang key, which is half of it. He said while returning the utensils to Xiao Ai: "If it weren't for my old dizziness, cataract recently, and the transplanted cornea, maybe I would have looked more closely." ”

Xiao Ai was very energetic when she heard the word "transplant", why do the people she meets now like transplantation for treatment? ”

Then he asked, "Uncle, when did you transplant your cornea?" ”

The uncle said: "Coincidentally, it was Valentine's Day night, and it was raining that day, so I remember it very clearly." ”

When Xiao Ai heard this, the nerves in his whole body seemed to be electrified, and goosebumps stood up. Is there such a coincidence? An idea came to Xiao Ai's mind, it couldn't be donated by the same person! Then he asked, "Which hospital is it?" ”

"The Seventh Hospital," the uncle said.

Xiao Ai felt that her curiosity had reached its peak now. It is now more certain that nine times out of ten their transplanted organs came from the same person. Maybe he can find out something related to his own experience. He said, "Uncle, since we both like this thing, I decided to buy it, how about we make friends and study it together?" ”

When the uncle heard this, he was delighted and said, "Okay! I'm in the front corner of the shop with a key, you can come, I'm in the store every day. The uncle paused and said, "My surname is Zhang, call me Uncle Zhang." I don't know what you call it? ”

Xiao Ai stretched out his right hand and shook hands with Uncle Zhang and said, "Call me Xiao Ai." ”
