Yang Nianzhong has pointed out the crux of the problem, the weight of this cross does not match its volume, so where did it run with less than a dozen grams of weight? In addition, this cross is a cube, and it is particularly thick, so there must be something greasy in the cross.

Everyone has curiosity, Yang Nianzhong's curiosity can't even catch up with 10 cats, and the curiosity of the grandmother is even more undiminished, neither of them spoke, one smoked and the other drank coffee, so he frowned and looked at the cross on the coffee table.

In fact, Yang Nianzhong was waiting, using these clues to guide the grandmother step by step to unlock the secret of this cross, and remove his role from the middle. The grandmother did not let her doubt any of her unconventional judgments, which is why she did so many things to verify the secret of the cross.

And with the current progress, Yang Nianzhong felt very satisfied, so Yang Nianzhong felt very relaxed, sitting there smoking a cigar, smiling, not in a hurry at all.

After a while, the old grandmother really couldn't figure out what kind of secret was in the cross and chose to give up, looking at Yang Nianzhong's smiling appearance, she shook her head helplessly and said.

"Little monkey, you won, I really can't find anything different about this cross, don't hide it, tell me what the hell is going on?"

As soon as he saw the old grandmother's convincing, he began to ask himself for help, and asked with a happy smile in the year of the goat. "The secret hidden by the weight of the dozen grams that grandma disappeared is inside this cross, but this cross is special."

"It's both your father's relic and the key to the safe, but I don't know how this cross unlocks the safe, so I don't dare touch him."

As soon as the old man heard Yang Nianzhong say this, he knew that Yang Nianzhong planned to make some changes to this cross, and it was possible to disassemble and change it for him, but Yang Nianzhong didn't know what the cross as the key had to do with the insurance lock of Henry Bank? How this key opens the lock.

As soon as he saw Yang Nianzhong's appearance, the old man smiled, picked up the pen and paper again, and began to recall what was the relationship between the key to this cross and the safe? The secret of how to open the lock of the safe lies at the bottom of the cross.

This cross is the keyhole of the square safe and the bottom of the cross, the square column is perfectly matched, insert your cross into the keyhole, and then turn the safe clockwise up to open the lock.

But this insurance is expensive and has a 6-digit password to open the safe, if you can't have this alone, you also have to have a 6-digit password to open the safe, which is also the key to the problem.

When Yang Nianzhong used his special function to check the internal space of the cross, he found that the bottom column of the cross had a counterclockwise design of the bolt, and the grandmother explained that the cross must be inserted in the safe and rotated clockwise to open the lock of the safe.

The secret inside the cross is to rotate counterclockwise, and then tighten the cross tighter and tighter, so that the bottom of the cross and the structure above do not produce any gaps, so that people can see that there is a secret in the cross, this design is very ingenious.

Now Yang Nianzhong already knows that the cross needs to rotate clockwise to open the safe, and to unlock the secret of the cross, it needs to rotate counterclockwise, plus Yang Nianzhong has used the most accurate caliper to calculate the diameter and width of the pillar at the bottom of the cross, and other important information.

Then Yang Nianzhong has nothing to hesitate, put the tools he bought in the toolbox are two small wrenches, take out these two wrenches, Yang Nianzhong looked at the old man and asked.

"Grandma, I have recorded the key to this cross, both in width and length, and in order to unlock the secret of this cross, the lower part of the cross must be opened."

"But I can't tell if the cross will break into two pieces if I twist it with a wrench, so I'd like to ask you to double-check if you really let me do it?"

The old man nodded firmly and told Yang Nianzhong, you can rest assured and boldly do it for me, even if you destroy this cross, once you get the promise of the old grandmother, Yang Nianzhong will no longer have anything to hesitate.

The upper end of the cross and the lower end of the cross were fixed with two wrenches, and then twisted counterclockwise, only to hear a rattle, the lower and upper ends of the cross column were really twisted, and did not break into two parts.

Then Yang Nianzhong put down the two wrenches, unscrewed the cross little by little with his own hands, and after disassembling it into two parts, Yang Nianzhong picked up the cross pillar at the lower end and put it in front of him, and saw that it was black inside, and he couldn't see anything.

At this time, Yang Nianzhong turned on the lamp, put the lamp on the coffee table, and brought the column to the bottom of the lamp, and you could see that there was something inside.

"I didn't expect that this pillar key to open the safe could really be removed, if I had known, I would have done it a long time ago, it's really old and useless."

Yang Nianzhong smiled slightly, opened the toolbox and took out a small pair of tweezers from it, and gently pulled out the lump of stuffed things in the column, and at first glance it was a rolled-up piece of paper, the paper had begun to turn yellow, but it was very strong.

The height and width of this paper is exactly the standard of a cigarette stuffed into the column of the cross, Yang Nianzhong took out this small paper ball from it, and gently opened it, and what was recorded on it was a piece of text, and there were many numbers.

But Yang Nianzhong was annoyed when he saw these words, why? These words are so strange, they don't look like English or French, Yang Nianzhong didn't know what was written on them, so he looked back at the old man and asked.

"Grandma, you see there is a text on it, but this text looks like both English and French, and there are some strange symbols, I don't understand what language it is, do you know?"

The old lady took the note, looked at it carefully, shook her head and said. "It's Hebrew, it's the Jewish language, but unfortunately I know both English and German, and I'm fluent in Polish, but I don't know Hebrew."

Yang Nianzhong was even more stupid when he heard the old man say this, the old man is a Jew, what is written on it is Hebrew script and language, and the old man can't read or read, so the words on this note have become a mystery.

Fortunately, Yang Nianzhong will carry a mobile phone or laptop with him, even if Yang Nianzhong does not have a computer, there is still a computer in the study room of the presidential suite for guests to use.

So Yang Nianzhong used the pen and paper he prepared to start recording these Hebrew words, and then ran to the study and began to check the meaning of these letters, what kind of words they composed together. It took more than two hours to understand that this one, which is only 10 cubic centimeters square, has the meaning of Hebrew words on both sides.
