"Here we are."

Mr. Grunfield, dressed like a little adult, dressed in a child's suit and tie, sat on a swing in his back garden, watching the fallen leaves on the ground begin to move without wind, and quickly gathered to form a string of numbers.

202906170115

This string of numbers, every day at the end of the month, at 14 o'clock in the afternoon, will inevitably appear on time.

Appears in all sorts of supernatural ways, as if by magic.

Sometimes it's in his notebook, sometimes it's in the form of water stains when he goes to the toilet, and what's even more amazing is that it's in his room with his clothes and the numbers formed by building block toys.

Without exception, it's all this string of numbers.

In 1977, Glenfield, who was only 9 years old, faced this string of numbers for half a year, from the initial panic to the later calm acceptance, he couldn't help but have such an idea in his heart.

He wanted to figure out what the numbers meant.

He is only 9 years old, he likes to read a lot of books, and it is rare to be buried in the library all day, and adults are so worried about his body that they tell him to go to the lawn to play more, maybe football is more fun than reading.

Grunfield refused, and he had to figure out what the string of numbers meant.

He began to consult books, trying to find answers in books, but it was not easy, and it was impossible to explain this as a textbook. Until one day, when he was pondering the number in the library, the librarian was already familiar with him, walked over and glanced at him, and said, "Isn't this time?" ”

"When?"

Little Grenfield wondered, "20:29:06? But what about the numbers that follow? ”

"No, I'm talking about the year and the month ......"

"Year and month? There are only 12 months in a year, where are there 20 months? ”

"No, the standard format for dates in the United States is MM/DD/YYYYY, and the standard format for dates in the UK is dd/mm/y

After the librarian finished speaking, he took the mop and left.

Grenfield suddenly realized, "Is it time?" ”

However, when the boy understood this, a bigger question arose, "If it's time, why is it 51 years later?" ”

That's half a century away!

Grunfield couldn't figure it out.

It just happened unexpectedly.

The 8-month figure appeared, changed, and after time, a longer string of more complex numbers was revealed.

And this string of numbers is so complicated that Grunfield can't figure it out.

So, he was born with this sense of mission, and this string of numbers must be about saving the world......

Well, although the numbers continued to appear on time at the end of the month after that, they never appeared again after Grenfield was 12 years old.

After that, Grunfield entered a high school where learning and life were more complicated, entered college, entered society, and entered the workplace...... I have long forgotten the string of numbers and life experiences.

Now he is 55 years old, he is already a high-level official at NASA, he has a wife and children, and the children are about to graduate from college, and a happy life is what describes him.

But......

Grenfield's eyes were confused for a moment, and he re-met Yu Ze's eyes, he secretly felt that this young man's eyes were so clear.

He knows this young man from China, and perhaps anyone in the United States who has not yet left society should know this young man who has been particularly popular recently.

Grunfield was surprised to hear his name called, didn't he just see this young man talking to the president?

Why do you come to take the initiative to say hello to yourself? No, how did the other person know his name?

It stands to reason that he is not a famous NASA official, there are so many celebrities here, it can't be his turn anyway, right?

Besides, how did the other party know his name?

"Hello, Mr. Yu!"

Grenfield, though surprised, replied quickly.

"Mr. Grunfield, can we talk?"

Yu Ze glanced at the man next to him.

The man was very clever, and nodded politely and walked away.

"Mr. Grenfield, remember this time?"

Yu Ze took out a note and handed it to Grenfield.

He was still wondering what Yu Ze was going to talk about privately with him, so he took the note in a daze and looked at it - 202906170115.

"What is this ......?"

Before Grunfield could finish speaking, the long-sealed memory instantly struck his brain, like a lightning strike.

"And this ......"

Yu Ze handed over another note, and Grunfield took it again in a daze, this time, not only the dusty memory, but also a feeling that he already knew the answer came to his heart.

"ICRS coordinates!"

Glenfield blurted out.

Yes, he remembered!

The experience of being a child makes this dusty memory really profound, even if it is forgotten with the passage of time, it is quickly recalled after triggering the keyword.

202906170115 don't say it, the second string of numbers, he also recalled.

Only then did he realize that when he was a child, he couldn't figure it out, and he found a number that many adults couldn't figure out for help, and it turned out to be ICRS coordinates!

This is normal, ICRS is the abbreviation of the International Celestial Globe Reference System, which belongs to the current standard of the Celestial Globe Reference System adopted by the International Astronomical Union, but it was only adopted at the 23rd Congress in 1997 and officially launched in 1998.

No wonder he couldn't understand the meaning of the numbers when he was a child, because it would be 20 years before the adoption of ICRS, and he would not be introduced until he was 30 years old!

"Why ...... You"

Grenfield stopped his words and looked sideways with a solemn expression, "Mr. Yu, please come with me." ”

They walked to another no-man's corner, Yu Ze motioned to the two guards to pay attention to the approach of the others, and Grunfield suppressed his excitement: "Mr. Yu, why do you know these two sets of data?" ”

"Mr. Grunfield, the apocalypse is also coming."

As soon as Yu Ze spoke, he suppressed Grenfield.

There are two reasons, the first is that these two sets of numbers are supernatural phenomena that he witnessed as a child, and he forgot them over time, and he can also recall them after triggering keywords, which is unforgettable.

The second reason is his position, he is the head of the Planetary Defense Coordination Office, a senior NASA official who is supposed to prevent the apocalyptic disaster on Earth, and is quite sensitive to the word doomsday.

After taking a few deep breaths, Grunfield calmed down: "Mr. Yu, why do you say that?" ”

"These two sets of data are time and ICRS coordinate systems, and maybe, Mr. Glenfield, you should verify them with your strength."

Sometimes curiosity and confusion are the best sources of motivation to drive one's actions.
