National Astronomical Observatories of China

Three days later.

"Yongchang, have you read the latest issue of *Nature*?"

Just as Lü Yongchang was sitting in his office, struggling with the significance hidden behind sonoluminescence, Fang Xu's voice came from the side.

He was slightly startled and looked up at Fang Xu. "Huh? No, I haven't. What's up?"

Looking at Fang Xu's mysterious expression, a hint of doubt flashed in Lü Yongchang's eyes.

*Nature*...

As far as he could remember, there shouldn't have been any major events in the academic world during this period.

"You really should take a look!" The mysterious look in Fang Xu's eyes grew stronger. "I've never seen such a fantastical thing in my life!"

A trace of unease flashed through Lü Yongchang's heart. He frowned tightly and asked softly, "Brother Xu, what on earth is going on?"

Fang Xu shook his head with a smile. "You... you're just too impatient!"

"Alright, I won't tease you anymore. An astronomical laboratory in the US published a paper in *Nature*. According to their observations, the sun has shown a lot of abnormal data in the past month."

"Based on these observational data, this laboratory deduced a conclusion."

"Hahaha, Yongchang, you definitely can't guess what their conclusion is!"

Just as Fang Xu was halfway through his words, Lü Yongchang's face suddenly changed drastically!

Hearing Fang Xu's question, Lü Yongchang murmured to himself, "The sun has entered its old age..."

Fang Xu, who was about to say this absurd conclusion, was slightly stunned. Then he looked at Lü Yongchang with a strange expression. "You... you said you haven't read the latest issue of *Nature*, right?"

Lü Yongchang ignored Fang Xu's words.

At this moment, his mind was already in chaos.

How could it be so soon?!

He remembered that in his previous life, this paper should have appeared two months later!

Could it be that... the changes in the sun have accelerated?!

The terrifying scene of the helium flash appeared in front of him again.

"Yongchang? Yongchang, what's wrong with you?"

Perhaps because Lü Yongchang's face was too pale, Fang Xu was also a little flustered. He shouted loudly for Lü Yongchang while turning his head to shout at a researcher beside him, "What are you standing there for! Call the medical staff quickly!"

Lü Yongchang slowly waved his hand, stopping the researcher's actions.

"I'm fine... no need to call the medical staff."

Fang Xu frowned tightly and said in a low voice, "This is still fine? Do you know what your face looks like!"

Lü Yongchang swallowed slightly and said softly, "Brother Xu, I need an astronomical telescope."

Fang Xu: "Huh???"

Lü Yongchang suddenly reached out and tightly grabbed Fang Xu's arm. "Brother Xu, trust me! Never mind the reason, I need an astronomical laboratory that can analyze solar data!"

Looking at the extreme fear in the depths of Lü Yongchang's eyes, Fang Xu swallowed slightly.

Although he didn't know what had happened, he still nodded slightly and said with a solemn expression, "Okay... I understand."

"And... show me the latest issue of the *Nature* magazine!"

Lü Yongchang gritted his teeth and added softly.

...

Looking at the extremely familiar data in the *Nature* magazine, the last trace of luck in Lü Yongchang's heart completely vanished.

The changes in the sun had actually advanced!

This was unreasonable!!!

Could it be that... the changes in the sun in his previous life were not a natural phenomenon?!

A terrifying thought gradually emerged in the bottom of Lü Yongchang's heart.

He quickly shook his head, throwing out the despairing thought in his mind.

"Knock, knock, knock!"

A knock on the door came.

Lü Yongchang didn't look up. He just stared blankly at the *Nature* magazine on the desk. "Come in, the door isn't locked..."

"Click..."

The sound of the spring lock came, and the door opened.

"Yongchang, I've applied to Minister Hong."

Fang Xu's voice came.

Hearing this news, Lü Yongchang's eyes lit up slightly. He looked up at Fang Xu standing at the door. "Have you contacted a reliable astronomical laboratory?!"

Fang Xu nodded slightly.

"Minister Hong takes your words very seriously and directly contacted the National Astronomical Observatories of China."

"Now it's up to you. When are you going to set off?"

Lü Yongchang suddenly stood up from his chair and looked at Fang Xu with burning eyes. "Of course, right now!"

"We have to be fast! I... we may not have time to waste..."

As he said this, a hint of bitterness flashed in Lü Yongchang's eyes.

Seeing this, the doubt in Fang Xu's eyes grew stronger, but he still nodded slightly. "I understand."

"There's a helicopter outside the laboratory right now. You..."

Before Fang Xu could finish his words, Lü Yongchang grabbed the pen on the desk and resolutely walked out of the office door.

...

Two hours later.

An armed helicopter slowly landed on the helipad in front of the National Astronomical Observatories of China.

Before the helicopter even stopped steadily, Lü Yongchang jumped down directly.

The whistling sound of the overhead propeller made a trace of nostalgic color flash in his eyes.

"Professor Lü, welcome!"

When the helicopter propeller slowly stopped, an old man with graying temples walked towards Lü Yongchang.

"You are..."

A bit of doubt flashed in Lü Yongchang's eyes.

"Hehe, I forgot to introduce myself." The old man had a big smile on his face and said cheerfully, "I'm Ye Nangeng, the director of the National Astronomical Observatories of China."

Lü Yongchang was slightly startled and quickly bowed respectfully to the old man. "Old Ye, I'm so blind that I didn't recognize you. I'm really sorry!"

Ye Nangeng waved his hand with a smile, not caring at all. "Don't say that!"

"Compared with controlled nuclear fusion, being the director of this observatory isn't anything to brag about!"

Suddenly, Ye Nangeng changed the topic.

"By the way, I heard from Minister Hong that you came here to study solar data?"

Lü Yongchang quickly nodded. "That's right!"

"What's the reason?" Old Ye frowned. "Could it be because of that paper in *Nature*?"

Seeing the change in Lü Yongchang's expression, Ye Nangeng immediately knew he was right.

As he led Lü Yongchang towards the observatory, he frowned and said, "Professor Lü, no offense."

"This paper in *Nature* has a lot of flaws!"

"The sun is currently still in its middle - aged prime, which is an undeniable conclusion."

"When we saw this paper, we also observed the sun. Although some data are indeed a bit abnormal, this definitely doesn't mean that the sun has entered its old age!"

Listening to Ye Nangeng's words, a bit of bitterness flashed in Lü Yongchang's eyes.

In his previous life, it was the same.

Everyone thought that these minor data changes of the sun were just a coincidence.

And because of this, humanity lost two whole years of escape time!
