"Don't worry, calm down and think about it!" Lin Mingyuan took the head of the violin and examined it carefully. Finally, he stayed on the lettering of that head. It's a hand-made violin. It's reasonable to say that the lettering should be engraved when it's made. Lin Mingyuan doesn't know the details of the production, but he guesses that it should be like this. The lettering of this violin... Feels a little abrupt, Lin Mingyuan felt that something was wrong and asked Wang Suxin, "have you ever received a gift of lettering before? Other musical instruments, too! "

"No, it's just this one. Generally, what Dad buys is finished products. The finished products don't provide lettering service. Of course, some also have some methods, such as laser, to engrave characters on the finished products."

"But this time, it was really engraved, and the depth of the words was different." Lin Ming is far away.

Wang Suxin pursed her mouth, nodded and said, "so the unreasonable place is on this?"

"I just have this conjecture. Do you mind if I damage the piano a little more?" Asked Lin Mingyuan.

Wang Suxin bit her lip. She obviously didn't mind. Although the piano was broken like this, it could still be stuck, but it couldn't be used any more. She wanted to deal with it as a souvenir, but Lin Mingyuan said so. She nodded and said, "OK, you can do it."

"I know it's a memorial for you, but it's also very meaningful for us to solve the case!" When Lin Ming was far away, Wang Suxin gave a gentle grace, and saw him pop up his sabre. He scratched it with the tip of the sabre and scratched off the paint on the surface.

Wang Suxin's eyes widened and watched the Qin continue to be damaged. As the paint on the surface gradually peeled off, Lin Mingyuan couldn't help laughing. It was really different inside. There were words on the Qin, but there were few words on it now. So Lin Mingyuan peeled off the paint more carefully with the tip of the knife. Time passed, and the two people in the car were very focused, Wang Suxin is toot small mouth, help Lin Mingyuan gently blow off the paint on the head of the piano, let the inside show.

A few minutes later, Lin Mingyuan stops and looks at the number on the piano head. This is a string of numbers, a total of ten. Lin Mingyuan has ruled out Wang Suxin's birthday, and it seems that it is not Wang Qiang's birthday. So what's the significance of this string of numbers here?

It can't be the number of the violin. When Lin Mingyuan thought of it, he shook his head and thought it was too unreliable.

"I'm a stranger to this number, not a score!" Wang Suxin identified and said.

"Well, it's not the score." Lin Mingyuan nodded, two people fell into a short thinking, decided to write down the number first, go back to check the information.

When driving back, Lin Mingyuan's mind was still the same number. The things were sent from England. That is to say, Wang Qiang was in England at that time. Now it seems that the secret is probably on this piano, that is, this group of numbers.

When the car was thrown away, Lin Mingyuan and Wang Suxin went around. After dinner, they strolled back to the place where they lived. After checking, Lin Mingyuan made sure that no one came in and he didn't ask anyone to clean it. When they got home, Lin Mingyuan took the mobile phone and sent the numbers to them. There was a special interpreter in the team to help them understand.

"I think all the way, I really don't know the significance of this number." Wang Suxin couldn't help saying.

"It doesn't matter. Let's think about it. I have an intuition. It should be the evidence left by your father!" Lin Ming is far away.

Wang Suxin picked his eyebrows like Lin Mingyuan, put his hands on his chest and said, "but... What is it?"

More than ten minutes later, Wang Suxin suddenly jumped up from the sofa and said, "this is a set of passwords, right?"

Lin Mingyuan shook his eyebrows and said, "yes."

"Ah? Uncle, you already know? "

"The key is what the password is. There are several commonly used passwords for domestic agents, but this group of numbers is not a sentence at all, so maybe I think too much." Lin Mingyuan stood up, went to the window, opened the window, and was about to light a cigarette. Thinking that Wang Suxin was also there, he said, "you go to the bedroom for a while, I'll have a cigarette."

Wang Suxin curled his lips and said, "you smoke. I'll think about it with you."

At the end of a cigarette, Lin Mingyuan received a reply from his subordinates, listing more than 20 possibilities. Lin Mingyuan called Wang Suxin over, took the reply and analyzed it one by one.

"The conjecture of this particular code is certainly wrong and illogical." Lin Mingyuan first denied one.

"The lyrics of this song, I remember, is an English song, but the corresponding lyrics are that I want to say I loved. That's not right, either Wang Suxin pointed to one of them and said, this one is also pass.

After some negation, there were only two left in front of them. One was from the Bank of Zurich, and the other was the address of a street in Germany.

"One Switzerland, one Germany." Lin Mingyuan tugged his cheek and gently rubbed it. Wang Suxin looked at him and ruled out more than 20 possibilities. Now the remaining two possibilities, she said: "can it be that street? You see, there's specific information on it. I'll use the street view map to have a look."

"I think it should be the bank. You think, the important things should be more reliable in the bank. Moreover, Swiss banks are famous all over the world. If your father stores things in places like Zurich Bank, they are too reliable. They are open 24 hours a day. They are anonymous storage boxes that only know the key but not the person. They have a lease term of at least 50 years. They are spacious and magnificent customer reception rooms How to get the key and password, and the VIP channel that can save lives. Switzerland is a permanent neutral country, so this group of numbers is probably the password of one of the banks! "

Wang Suxin, who was turning over the map, raised his head and blinked. He thought that Lin Mingyuan's analysis was right, and then said, "so we... Go to Switzerland? But it's not good to have only a password, at least a key or something... "

"So, do you think you have a key or something at home?" Lin Mingyuan asked with a smile.

A question got Wang Suxin into thinking. At last, he shook his head and said, "I haven't seen it. Except for the key to the door, my father hasn't taken the key to the house!"

Lin Mingyuan knocked on the screen and saw the street map jump out. It was the street number. It was a street in Hagen, Germany. Originally, it was no surprise, but Lin Mingyuan noticed that according to this address, a key shop was found. Yes, there are all kinds of shops with locks and keys in the streets of China.

This seems to be a clue, thought Lin Mingyuan.
