"Accidentally? Of course, it's not accidental, but if it's not accidental, what do these four words mean? Are these four words related to this emperor's tomb? Seongnam frowned and analyzed. Just when Chengnan was restless, suddenly Chengnan's eyes skimmed at a row of stones under his feet, each of which was engraved with an Arabic numeral, a total of ten Arabic numerals. "Officer Zhang? Is this the weird thing you just said? Seongnam asked, pointing to the rocks in front of him.

"That's right, you see these numbers are like the buttons on your phone." Zhang Mei nodded.

"Wait!" Seongnam suddenly raised his hand and cut off Zhang Mei's speech. "What's wrong?" Zhang Mei looked at Chengnan strangely. "A cell phone? Digit? Strange note? Seongnam said as he walked around like a headless fly. Suddenly, Cheng Nan's eyes flashed, and he looked up at Zhang Mei with excitement and said, "You said that each of them carried such a note, so does it mean that this note is very important?" ”

"Definitely, and I think this note must have something to do with this grave? You say, why don't they come down with this thing? Zhang Mei naturally understood this, but she didn't know what these had to do with what she just said.

"Because it suddenly occurred to me that the mobile phone left by Han Xiao is likely to tell us how to open this door, because now only we can mention him for revenge, and if we want to mention him for revenge, only let me go in and catch which masked man, so this reason is also valid, second, and if the mobile phone he told us really wants to tell us how to open the stone gate, then if it is not Han Xiao's mobile phone that can let us enter the stone gate, then this method of opening the stone door is related to the mobile phone, I couldn't figure out what this stone gate had to do with my mobile phone, but just now Officer Zhang's words reminded me! Seongnam became more and more excited.

"Which word?" Zhang Mei was puzzled. "You say the numbers on those rocks are like the keys on your phone! That's right! Why are there these numbers outside these stone gates? What are these numbers for? Apparently these numbers should be the code used to open the stone door? I've said before that this kind of permutation of numeric ciphers has been around since ancient times. The more Seongnam spoke, the more excited he became.

"But even if Han Xiao wants to remind us that what is needed to open the stone door is a password, and what is needed is to press these digital stones regularly, but we don't know what the password is?" Zhang Mei said depressedly.

"Is it possible that the password is this?" Seongnam shook the note in his hand and smiled. "Huh?" Zhang Mei was stunned for a moment and wondered: "This matter, Chinese characters are not numbers, what could be passwords?" ”
