"Sir, please wait a minute."

When the bank manager saw the key, his face tightened, and his attitude became respectful.

He opened the drawer, first took out an unopened pair of white gloves and put them on, then took out a magnifying glass, and then carefully took the key in his hand and examined it carefully, as if admiring a peerless antique.

The whole process was actually not long, and after only a few breaths, the bank manager returned the key to Li Renjie and said with a smile: "Sir, you are right, you do have something to put here with me." Excuse me, do you need someone to bring something over now? ”

"It would be great if it could be sent here."

Li Renjie thought that the other party would take him to a remote and mysterious place, which would be in line with the atmosphere of underground trading.

However, it would be nice to be able to bring things directly to the bank, at least it looks very formal, and the chances of accidents are very small.

"Wait a minute."

The bank manager first instructed the secretary to serve Li Renjie the best refreshments, and then made an encrypted phone call and reported the number on the key that Li Renjie had brought him.

For the next hour, Mr. Li waited in the office of the bank manager, a talkative man who told many funny French stories to pass the time.

It wasn't until the bank manager's mobile phone rang that he got up and said to Li Renjie: "Sir, the things have arrived, let's go down." ”

"Okay." Li Renjie nodded lightly and followed the bank manager's footsteps to the bank vault downstairs.

The bank vault is divided into two layers, inside and outside, and what Li Renjie went to was only the outer layer, but he had to go through various cryptographic verifications before entering.

Four heavily armed security guards stood in the four corners of a metal box.

"Please, sir."

The bank manager took Li Renjie to the metal box, and from the beginning to the end, he did not ask Li Renjie what his surname was, nor did he even introduce himself, but only called Li Renjie "sir".

From this point of view, the Merovingian family attaches great importance to privacy, for them Li Renjie is just a customer, and there is no need to know so much information about the customer.

The bank manager opened the key and entered the corresponding password, and the metal box was opened, revealing a wooden box the size of a suitcase.

The wooden box looked as old as the key, with the number "Seven Three Seven" engraved on the top.

The bank manager carefully took out the wooden box with his white-gloved hands and put it on top of the metal box, then turned to face Li Renjie and said with a straight face: "Sir, I need to warn you before opening the box.

Each chest is equipped with a specific key, and the chest contains a built-in bomb that will detonate the contents of the box if the key is not right.

Of course, the person who opened the box would also be killed. ”

His voice paused slightly, and he asked with a smile,

"Sir, do you want to open the box?"

"Yes, I'm going to open the box." Li Renjie nodded in response.

"Good luck." With a wave of his hand, the bank manager and the four security guards retreated into the corner to prevent them from hurting them by detonating the built-in bomb inside the box.

To be honest, Li Renjie was a little nervous in his heart, except that the amount on the key matched the number on the box, he did not have any confirmation that the key in his hand was to open the box, and he was also worried that the built-in bomb would be detonated.

Taking a deep breath and slowly exhaling it, after calming down his good mood, Li Renjie resolutely inserted the key into the keyhole, and then slowly turned the key.

"Click."

As the key turned, there was a snapping sound of a machine spring, followed by a slight bounce of the wooden box lid upward.

It didn't explode, and the key managed to open the box.

The bank manager also looked relieved, waved his hand to let the four security guards out first, and then said to Li Renjie: "Sir, I will turn off the cameras here for the time being, and you can enjoy a private time here." If you're done, you can press the green button on the wall and I'll open the door from the outside. ”

Li Renjie glanced up and found that the camera's flashing red light had gone out, indicating that it had stopped working.

Seeing the green button on the wall, he nodded in response, "Thank you, I believe I won't lose too much time here." ”

"Sir, please." The bank manager said and stepped out and had the door of the safe closed.

Li Renjie was the only one left in the room, and he lifted the lid of the box.

Inside the box was only a letter sealed with a wax seal, and there was not a single word on it.

Li Renjie picked up the letter and looked at the light, and after finding no abnormality, he destroyed the wax mark, opened the envelope, and took out a piece of stationery from inside.

Spreading out the letter, Li Renjie found that there were some numbers and English letters on it, which were basically separated from the middle, and some were only a third, and it was completely impossible to identify what was written.

Li Renjie just glanced at it and recognized that this was an ancient cipher design, the letter paper was originally wrapped around an object, and then something was written on it, and when the letter paper was opened, this situation would appear in front of him.

Unless you find the object that the letter paper was entangled in the first place, it is impossible to solve this puzzle.

Li Renjie looked at the letter paper for a moment, unable to distinguish the contents of it, and then took out his mother's comb and tried to wrap the letter paper around it.

After several attempts at different angles, the separated handwriting came together, and all the words were connected.

What is it?

Li Renjie frowned, there was nothing but a string of numbers scrambled by English.

"Boom."

When the handwriting was combined, it took less than three seconds for a string of fires to suddenly unleash the comb and the letterhead.

The sudden fire was like a ghost fire, but in fact it was because the letter paper and the comb were smeared with different drugs, and when the two were rubbed, they would cause the current reaction, which was a method of burning after reading, mainly used for secrecy.

In three seconds, ordinary people can't remember the string of numbers that are scrambled by the English alphabet, but for Li Renjie, it is not a problem, it has been firmly imprinted in his mind.

Li Renjie simply threw the envelope on it and burned it, waiting for everything to be burned to ashes before pressing the green switch.

"Squeak."

The bank manager opened the door and saw the ashes on the ground and understood everything, and did not ask much, but just stretched out his hand and said with a smile: "I hope Sir is satisfied with our service, according to the rules, you have to hand over the key to us before you can leave." ”

"Thank you, I am very satisfied with your service." Li Renjie handed over the ancient key and left the bank safe.
