Cape Town, South Africa, Standard Chartered Bank Safe Lobby.

"Yes, sir," said a black manager, who was speaking in authentic English to Miao Kun, who was disguised in disguise, "Our counter numbers are not Arabic numeral numbers, but are sorted alphabetically according to the account number provided by the customer.

"It's still ......," he pursed his thick lips and smiled with a mouthful of small white teeth, "The practice left over from the Mandela period can't be changed later!"

"Oh...... Hehe......" Because of the mask, Miao Kun even had to be extremely careful with his ordinary smile, for fear of revealing flaws, "I have heard my brother mention this!"

"In that case, please take a look, there should be no problem with my brother's account, right?" As he spoke, Miao Kun picked up the pen and wrote the five English letters "Tytal" on the paper.

"Wait a minute," the bank manager pulled out his tablet, looked it up, and quickly nodded, "yes, we do have this account number!"

Oh yes!

Miao Kun was silent on the surface, but he was already ecstatic in his heart, he didn't expect that his guess would really come true.

"That'...... Do you need to open it now, sir?" asked the bank manager politely.

"Of course...... Miao Kun nodded and said, "Otherwise, I came all the way from the United States, I can't just chat with you, right?"

"Hehe, you're kidding!" the black manager laughed.

"My brother also told me that to create an account with you, you must have two identical letters, right?"

"Yes, and it's case-sensitive...... the bank manager smiled, "but ...... That was the rule a long, long time ago, and now we open the safe, but it's not that troublesome!"

"Hmm......" Miao Kun glanced left and right and asked, "Then what do I need to do next?

"Oh...... No, no, no...... There is no need to register, we will protect the privacy of our customers 100%, ......" The black manager hurriedly and politely pointed to the inside of the bank, "You come with me! Please ...... here"

"Thank you very much!" Miao Kun thanked politely, but he couldn't help but show a hint of trium in his eyes. In fact, long before he arrived, he had already done a lot of homework and learned about the safe procedures here.

Unexpectedly, there is really a safe account called "Tytal" here, and it is obvious that this mysterious safe cabinet is the real clue left by Green!

There is still a big gap between the safe deposit box area of Standard Chartered Bank in South Africa and some large banks, and the area is far worse than Miao Kun imagined.

So when the bank manager led him into a small secret room, he even felt a little depressed wearing a mask.

Since there weren't many safes in the room, the manager quickly found the one marked "Tytal".

At this moment, Miao Kun finally understood why Green had hidden the fake diamond in the Tidal Generator, but why he didn't use the word "Tidal" as a password.

Because, Standard Chartered Bank has a rule to open an account, the account must contain two identical letters, and it must be case-sensitive.

That's why Green uses the technical abbreviation of "Tytal" as a password. It is precisely because of this that Miao Kun smelled the clues hidden behind Green and chased him all the way here.

"Sir," the black manager opened an old-fashioned keyboard under the safe and said to Miao Kun, "Now please type the password!"

"Oh...... Okay!" Miao Kun approached the safe and looked at the old-fashioned keyboard, but saw that the keyboard was similar to the current computer keyboard, with both letters and numbers on it.

Call......

Since the mask couldn't dissipate sweat, all the sweat was left along Miao Kun's neck and around his collarbone, soaking the shirt on his chest, which was very uncomfortable and awkward.

But at this time, Miao Kun didn't care about anything else, he exhaled softly, rubbed his hands unnaturally from the sides of his shirt, and then pressed the string of letters and numbers "GDP2056" on the keyboard with bated breath.

These letters and numbers are the diamond codes that Green left behind, and the ones written after "Tytal" on the generator box where the fake diamonds are hidden.

Miao Kun believes that since "Tytal" is an account number, the "GDP2056" behind it must be the password.

At this moment, he typed the string of letters and numbers on the keyboard as it was.

After entering, he immediately held his breath and stared earnestly at the two red lights on the safe.

Backbite......

As the safe beeped, one of the red lights turned green.

Wow......

Miao Kun raised his arm excitedly, and just wanted to touch the safe, but soon found that there was a red light on the safe that had not yet turned green.

"Oh......" Miao Kun suddenly realized, hurriedly took out a fingerprint from his pocket, and said to the black manager, "My brother has passed away, so I should be in line with the rules by wearing his fingerprint and fingerprinting, right?"

"Hmm...... In principle, as long as you can open the safe, we will not pursue your identity, but sir......" said the black manager, "Are you mistaken? You can also see, what you need to open is the first locker of our bank, which was still used with a key at that time, and did not need to enter fingerprints!"

"......" Miao Kun suddenly trembled, as if struck by lightning, he didn't expect that his homework was not done properly, and he thought that with Green's fingerprint, he would be able to open the cabinet!

Frustrated, he reached unnaturally into his pockets with his hands. However, how could he have any keys in his pocket?

"Sir......" the manager hurriedly asked, "your brother, is there any confusion? Did he give you the key?"

"Hmm...... What's this...... This ......" Actually, Miao Kun's face is now covered with sweat, but because he is wearing a mask, he can't see it at all. "Hmm...... Of course...... Of course I did......

"But......" Miao Kun hesitated for a long time before he hesitated, "the key...... Key...... It's not going to fall to the United States, is it?

"Hehe......" he laughed unnaturally, "brother, do you think this is the most bitter joke in the world?"

"No, no, ......no," the black manager hurriedly waved his hand and said, "Don't worry, it's okay if you don't have a key! You know that the PIN code is fine, after entering the PIN code, even if you don't have the password and key, the safe will open automatically!"

"What the hell? secret code?" Miao Kun frowned.

It's a 13-digit password, and the password is composed entirely of English letters. At the time, this was a first for us at Standard Chartered!", said the black manager, "We added the security code to the lockers!"

"At the time, the 13-digit cipher was synonymous with being impossible to decipher, and the bankers of the older generation called it foolproof......"

"Crypto Code...... English Alphabet...... 13-bit ...... 13...... "Miao Kun pondered carefully, the gears of his thinking were flying at high speed, and his brain was about to boil.

"Sir...... "Sir," the black manager cautiously urged, "can you remember that your brother told you about the code, and if there is no code, then ...... Well...... Then ......"

"Wait a minute! I ...... I ......" Miao Kun's eyes lit up suddenly, and he said excitedly, "I seem to remember, and I ask, will these 13-digit secret codes not be repeated?"

"Hmm...... What's this...... I have no comment!" the black man smiled, his expression already stiffening.

"Good...... I...... I'm almost remembered, come on......"

As he spoke, Miao Kun pressed one letter after another on the keyboard, and every time he pressed a letter, he had to think for a long time, although he wasted a lot of time, but the 13 letters were finally entered.

As a result, before Miao Kun had time to make mental preparations, another red light on the safe turned green, and the safe clicked and popped up automatically......
