Yang Nianzhong had already activated his own special function perspective, and saw clearly that there was a void space in the lower half of the sterling silver cross, and there was a roll of things in the space that was not the same as the density of the sterling silver cross, which proved that there was something in the column in the lower half of the cross.

But sitting opposite Yang Nianzhong was a 90-year-old grandmother, don't look at this old man is very humorous, but the so-called old man is an old traitor and an old spirit, plus this old man has taught a student all his life.

If there is a little abnormality in himself, he will be seen by the old man, and Yang Nianzhong has hidden the special function for so long, and it will definitely be discovered by the old man.

Therefore, Yang Nianzhong did not dare to blatantly tell the secret inside this cross, but looked at the old man with this cross and said. "Grandma, did you say that this cross was handed down by your father, the key to open your father's safe at Henry's Bank in Lausanne, Switzerland?"

When the old man saw Yang Nianzhong, he looked left and right at the cross around his neck, and looked at it for more than ten minutes before he asked such a question, and the old grandmother smiled and pursed her mouth.

"The little monkey is right, this cross is the key, the technology back then was not as developed as it is now, and it was a password, a fingerprint, and a red film to open the safe."

"Instead, you need a special key, which can be any item, as long as the size is right, Henry Bank will find a professional locksmith to make the lock of the safe, and then use the item you choose as a key to open it."

"This cross was left to my father by my grandmother, so my father used this cross as a key to lock his safe."

Yang Nianzhong nodded, Swiss locksmiths and Swiss watchmakers, that is world-famous, how big a place is the watch, the Swiss can make the watch so fine, it is too simple to make a lock that is opened with a cross.

And this cross is the key used by the old man's father to open the lock of the safe, so this cross cannot be moved, but if this cross is not moved, how can the contents be taken out and made public, it is possible that the roll of paper hidden in the cross is the password left by the grandmother's father.

But there is no need to write such a large piece of paper and stuff it inside the cross for a few digits, so Yang Nianzhong began to frown again, pulled down the chain of the cross in front of the old man, and then gently threw the cross into the air, and saw the big head of the cross rushing down and falling on the table.

"Smack,"

"Smack"

This voice is very ugly, and the table top is very hard, Yang Nianzhong didn't dare to throw the cross on the table if it was more than ten centimeters high, and every time the cross fell on the table, it was head-down, Yang Nianzhong had an idea at this time, looked at the old grandmother and said with a smile.

"Grandma, the key to your father's legacy of the safe and the wealth inside lies in this cross, if I guess correctly, this cross is not only a key, but also a hidden code."

The old grandmother sat opposite Yang Nianzhong, Yang Nianzhong originally thought that if he said such a thing, the old man would be very excited and happy. But I didn't expect the old lady to be very calm, took a sip of the coffee cup, put the coffee cup on the table mat in front of the air-conditioned room, and looked at what Yang Nianzhong said.

"Child, have you discovered any secret in this cross? In that case, then you can go and prove it to me. ”

is worthy of being a teacher all his life, you look at what people say, let you go and show me the proof, and you don't feel sorry for the only relic left to him by your father, which is particularly special in Yang Nianzhong.

Yang Nianzhong knew that this cross was of great significance to the old man, this was the only thing his father left him, and it was also the key to open the safe, Yang Nianzhong did not dare to destroy this sterling silver cross.

So Yang Nianzhong began to prove to the old man that there was indeed a secret in this cross through various experiments, how to prove it? Easy to do Yang Nianzhong hurriedly returned to his bedroom, got dressed, and then walked out, while arranging his collar, he looked at the old man and said.

"Grandma, you rest in the house first, if you want to use anything, call the hotel switchboard and ask them to prepare it for you, I will go buy some items and come back soon."

When the old man saw Yang Nianzhong, he went out in such a hurry and smiled, and said goodbye to Yang Nianzhong while instructing.

"Kid, it snowed again in the early hours of yesterday morning, and it will definitely be very cold outside, so you should be careful not to catch a cold when you go out."

Yang Nianzhong saw that the old man was so good to him, and he also felt warm in his heart, Yang Nianzhong grew up living with his mother since he was a child, and there were two mothers and sons in the family, and he was not loved by grandfathers and grandparents like grandparents.

Therefore, Yang Nianzhong's growth trajectory lacks the important link of the love of the main parents, and when he saw that this grandmother was so kind and cared about himself, Yang Nianzhong found the missing emotion in this grandmother.

So Yang Nianzhong smiled slightly, hurriedly ran to the old man's side and hugged the old woman who stood up, kissed the old man's cheek and said.

"Got it, grandma."

And what about the old grandmother, seeing Yang Nianzhong's appearance, he smiled and patted Yang Nianzhong's brain, Yang Nianzhong ran out with a smile, why did Yang Nianzhong run out? I went to the mall to buy the tools I needed.

These tools include electronic scales for detecting the weight of jewelry, such electronic scales do not look small, but the weight of the detection can definitely reach a difference of 1/10,000, which is specialized in identifying the weight of diamonds.

The other tool is the caliper, which is also jewelry-grade, you don't look small, but the length and width of the jewelry are measured with great accuracy.

In addition to these, Yang Nianzhong also bought some other tools, let's not list them one by one, after preparing these tools, it was almost noon, Yang Nianzhong came out of the mall, and actually saw a Chinese couple selling traditional Chinese delicacies such as fried chestnuts with sugar on the street corner.

Steaming smoke came out of the machine, and the aroma of sugar-fried chestnuts could be smelled from dozens of meters away, and there were many people who bought sugar-fried chestnuts.

As soon as Yang Nianzhong saw these sugar-fried chestnuts, he couldn't help but swallow his saliva, and then thought of his grandmother waiting for him in the hotel room, Yang Nianzhong's eyes lit up, and he hurriedly ran in front of the Chinese couple and asked in Mandarin.

"Hello, how much does it cost to fry chestnuts with sugar?"

The Chinese couple was busy with their heads down, looking for money for customers to sell sugar and fried chestnuts, and suddenly they heard Mandarin and felt very cordial, and when they looked up, they saw a young man with a toolbox in his hand, smiling in front of the couple.

As soon as he saw that the two siblings and husband were particularly happy, the man smiled and came over. "Where is the little brother from? Mandarin is really standard, fried chestnuts in sugar are two euros a piece, and the weight is 200 grams. ”

"For the sake of our compatriots, how about I give you a cheaper price, and if you give 4 euros, I'll sell you 500 grams?"
