A trace of excitement flashed in the mysterious man's eyes, but he was still unhurried, and said: "Yes, this tower was built in the Tang Dynasty, and its architectural style is also rare in the Tang Dynasty.

And the two are very different, the tower is cylindrical, and the one we are in now is spherical, which is a miracle in the history of architecture! ......”

Listening to the introduction of the mysterious man's profession, Nie Tian remembered a person.

At this time, Brother Huo, who was a little impatient, reminded: "Sir, can you talk about the key points first?" ”

The mysterious man realized that his words were a little long, and said simply: "After I checked a lot of historical materials, I determined that it should have a great relationship with the Empress of the Wu Clan, and the character on the table is her real name.

She has killed Confucianism and worshiped Buddha all her life, and she is convinced of the reincarnation of cause and effect.

I think the password of this mechanism should be her birthday, one is to correspond to her own name, and the other is to indicate that the destiny is for her. And her birth date has been researched to have four possibilities. ”

When everyone heard this, they couldn't help but feel worried, and they asked if they could be more sure.

The mysterious man continued: "The first theory is the seventeenth day of the second lunar month.

The second is the fifteenth day of the first month of the seventh year of Wude, and the eight characters are Gengchen Gengchen Gengchen, but this is 4 years different from the year of birth.

The third is the widely circulated 23rd day of the first month of the lunar calendar, but at that time, Wu Zetian frequently changed the year name and had advanced the date by two months, so it should be the 23rd day of the second lunar month.

The fourth argument is the most complicated. Because the solar calendar and the lunar calendar are repeated once in 19 years, the calculations are verified by using the first three one by one. There are three possible outcomes:

1. Verified by the 23rd day of the first lunar month of the third lunar calendar, the 23rd day of the second lunar month can be obtained as her birthday.

2. Take the second type, that is, the 15th day of the second lunar month.

3. If you take the first type, it is the fourth month of the lunar calendar. ”

Everyone listened to the mysterious man's explanation, and the more they listened, the more confused they became.

Brother Huo was puzzled, so he simply asked directly, "Which one does that gentleman think?" ”

The mysterious man analyzed: "I can be sure that it is the second month of the lunar calendar, because through four statements or verifications, it all points to the second month of the lunar calendar, but I am not sure of this specific date." ”

Listening to the mysterious man's analysis, Nie Tian thought about his recent bizarre experiences in the "Foguang Temple" and the "Fifth People's Hospital" and "on the train", as well as the trance feeling when he touched the stone platform just now.

I feel that I must have some kind of connection with this tower, if Wu Zetian's birthday is February 15 of the lunar calendar, then it is the same day as my birthday, is this a connection?

Thinking of this, Nie Tian said to the mysterious man: "I think it's the fifteenth day of the second lunar month. ”

Everyone turned their heads to Nie Tian, and the mysterious man asked, "Little brother, how did you analyze it?" ”

Nie Tian was a little embarrassed, smiled, and said, "It's just feeling!" ”

Everyone was full of black lines, and Brother Huo said: "Don't mess around, how can this matter rely on feelings!" ”

The mysterious man thought for a while and said to everyone: "Actually, I am also more inclined to fifteen, since the little brother said that the feeling is fifteen, then I will believe his feelings."

There are many things in life, and in the end, it doesn't work out, it's that little luck, are you willing to bet on the fifteenth? ”

Everyone was a figure licking blood on the tip of a knife, and when the mysterious man said this, he was aroused by his gambling temperament and agreed one after another. Only Mao San had a bitter face, but he didn't dare to gnaw.

The mysterious man slowly pressed the number and waited for a moment without any movement.

Several people stood erected in the dark tower hole, breathing in the damp and thin air, quietly waiting for the passage to open, not daring to make a sound, listening attentively, fearing that a moment of negligence would miss the sound of the mechanism opening.

The confined space is already depressing, and now I hope that it is losing little by little, making everyone feel more depressed and gradually anxious.

One minute, two minutes...... Until Brother Huo broke the silence and said, "Sir, I guess there is still a mystery in this mechanism, think about it again, have you forgotten anything?" ”

The mysterious man fell into deep thought, thinking about what was missing, and everyone expressed their opinions, and the arguments grew louder and noisier, and the emotions became more and more anxious.

Brother Huo snorted violently, and everyone immediately quieted down and looked at Brother Huo.

Brother Huo said in a calm and calm tone: "Be quiet, let Mr. think about it, don't disturb Mr.'s clues." ”

Nie Tian secretly admired Brother Huo in his heart, after all, he was the boss and could be so calm at any time.

Nie Tian retracted his somewhat chaotic thoughts and refocused his attention on the stone platform, why was the mysterious man sure that the password was three, and what was the purpose of the hole in the word.

If the hole was originally inlaid with "black fluorescent beads", and it was most likely the archaeologist Xiao Li who took it, could this mysterious man be him?

If it was him, then what was the purpose of him taking such a big risk, colluding with gangsters, and going down the tower without permission?

Nie Tian decided to find an opportunity to test the mysterious man and confirm whether he was the archaeologist Xiao Li.

Looking at the mysterious man who was still pondering, he asked softly, "Sir, do you have a clue?" ”

The mysterious man shook his head and said, "The passage is not opened, but the anti-theft mechanism is not triggered, this is unreasonable, could it be that there is no anti-theft mechanism here?" ”

After a pause, he confirmed his thoughts, and said to Nie Tian: "This design will not be without an anti-theft mechanism, if the password we pressed is wrong, the anti-theft mechanism has already been triggered." Then prove that our password is correct! ”

Nie Tian asked suspiciously, "Sir, why are you sure that the password is three digits instead of other digits?" For example, add the number of the year she was born. ”

Brother Huo wanted to stop Nie Tian from disturbing the mysterious man's thinking anymore, but he felt that the question was quite reasonable, and he listened curiously.

The mysterious man explained: "In ancient times, there were four types of chronology: 1. The chronology of the year of the prince's accession to the throne. But this is the pre-Han chronology, which can naturally be ruled out.

2. Chronological method. It has been there since Emperor Wu of the Han Dynasty, and the Empress Wu of the Wu family has a total of seventeen years since the title of the Emperor of the Lin Dynasty, and she has changed the era name frequently, so it can be inferred that she does not care about the number of the year name. Her birth period is also the so-called former dynasty, with the arrogance of her empress, she should not use the era name of the previous dynasty, right?

3. Chronological method of cadres and branches. This kind of is based on ten heavenly stems and twelve earthly branches, forming sixty chronological numbers, which is often referred to as sixty years and one jiazi. The mechanism here is numeric, so it does not match the trunk number, and it is also excluded.

Fourth, it is a combination of era name and cadre branch, I don't need to explain, you also know that it can be ruled out.

From the technical level, it is already a small probability that the three- to four-digit cryptographic mechanism is selected by ten digits, and the anti-theft design is already foolproof. And this kind of design was already a kind of limit for the time, right?

Considering that the empress's birthday is the second month of the lunar calendar, it can only be three digits. ”

The Black Earth Gang heard it in a fog, only Nie Tian understood what it meant, and confirmed: "I understand, what Mr. means is that the year cannot appear here through analysis, so only the month and date remain."

And the Empress Wu was born in February, so with the date, it is naturally three digits. ”
