Three days later.

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

Just as Lü Yongchang was sitting in his office pondering the meaning behind the sonoluminescence phenomenon, Fang Xu's voice came from the side.

He was slightly taken aback, then looked up at Fang Xu: "Huh? I didn't see it, what's wrong?"

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

Nature...

As far as I can remember, nothing major should have happened in academia during this period.

"Then you really should go see it!" Fang Xu's eyes grew even more mysterious. "I've never seen anything so fantastic in my life!"

A sense of unease flashed through Lü Yongchang's mind. He frowned and asked softly, "Brother Xu, what exactly happened?"

Fang Xu smiled and shook his head, saying, "You... you're just too impatient!"

"Alright, I'm not teasing you anymore. An astronomical laboratory in the United States published a paper in Nature. According to their observations, the sun has shown many unusual data in the past month."

"Based on this observational data, the laboratory has drawn a conclusion."

"Hahaha, Yongchang, you'll never guess what their conclusion will be!"

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

Upon hearing Fang Xu's question, Lü Yongchang muttered to himself, "The sun has entered its aging period..."

Fang Xu, who was about to utter this absurd conclusion, paused slightly, then looked at Lü Yongchang with a strange expression: "You...you said you hadn't read the latest issue of Nature?"

Lü Yongchang ignored Fang Xu's words.

At this moment, he was already in a state of utter confusion.

How could it be so fast?!

I remember in my previous life, this paper appeared about two months later!

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

The terrifying scene of the helium flash reappeared before his eyes.

"Yongchang? Yongchang, what's wrong?"

Perhaps because Lü Yongchang's complexion was so terrible, Fang Xu also panicked. He called out Lü Yongchang's name loudly while turning to the researcher next to him and shouting, "What are you standing there for! Quickly call the medical staff!"

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

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

Fang Xu frowned deeply and said in a low voice, "This is nothing? Do you know how pale you look!"

Lu Yongchang swallowed hard and said softly, "Brother Xu, I need a telescope."

Fang Xu: "Huh???"

Lu Yongchang suddenly reached out and grabbed Fang Xu's arm tightly: "Brother Xu, trust me! Forget the reason, I need an astronomical laboratory that can analyze solar data!"

Seeing the extreme fear deep in Lü Yongchang's eyes, Fang Xu swallowed hard.

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

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

Lü Yongchang gritted his teeth and added softly.

...

As he looked at the extremely familiar data in the Nature magazine, the last glimmer of hope in Lü Yongchang's heart was completely extinguished.

The sun's changes have actually occurred earlier than expected!

This doesn't make sense!!!

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

A chilling thought suddenly surfaced in Lü Yongchang's mind.

He quickly shook his head, trying to shake the despairing thought out of his mind.

"Knock knock knock!"

A knock came at the door.

Lü Yongchang didn't look up, just stared blankly at the Nature magazine on his desk: "Come in, the door's unlocked..."

"Click..."

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

"Yongchang, I have already applied to Minister Hong."

Fang Xu's voice came through.

Upon hearing this news, Lü Yongchang's eyes lit up slightly. He looked up at Fang Xu, who was standing at the door, and asked, "Have you contacted a reliable astronomy laboratory?!"

Fang Xu nodded slightly.

"Minister Hong took your words very seriously and contacted the Xia State Observatory directly."

"Now it's up to you. When do you plan to leave?"

Lu Yongchang suddenly stood up from his chair, his gaze fixed intently on Fang Xu: "Now, of course!"

"We have to be quick! We...we might not have any time to waste..."

At this point, a bitter look flashed in Lü Yongchang's eyes.

Seeing this, Fang Xu's eyes showed even more confusion, but he still nodded slightly: "I understand."

"There are helicopters right outside the lab right now, you..."

Before Fang Xu could finish speaking, Lü Yongchang grabbed the pen from the desk and resolutely walked out of the office.

...

Two hours later.

An armed helicopter slowly landed on the helipad in front of the Xia Kingdom Observatory.

Before the helicopter had even come to a complete stop, Lü Yongchang jumped out.

The roar of the propellers overhead brought a touch of nostalgia to his eyes.

"Professor Lü, welcome, welcome!"

As the helicopter rotor slowly came to a stop, an elderly man with graying temples came to greet Lü Yongchang.

"You are...?"

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

"Hehehe, I forgot to introduce myself." The old man said with a smile, "I am Ye Nangeng, the director of the Xia Kingdom Observatory."

Lu Yongchang was slightly startled and quickly bowed respectfully to the old man: "Elder Ye, I was blind to your greatness, please forgive my rudeness!"

Ye Nangeng waved his hand with a chuckle, saying nonchalantly, "Don't say that!"

"Compared to controlled nuclear fusion, I, as the director of an observatory, have nothing to say!"

Suddenly, Ye Nangeng changed the subject.

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

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

"The reason?" Old Ye frowned deeply. "Could it be because of that paper in Nature?"

Seeing the change in Lü Yongchang's expression, Ye Nangeng instantly knew that he had guessed correctly.

As he led Lü Yongchang toward the observatory, he frowned and said, "Professor Lü, it's not that I'm saying this."

"This paper in Nature is full of dubious quality!"

"The sun is currently in its prime, which is an indisputable conclusion."

"While reading this paper, we also observed the sun. Although some data is indeed a bit abnormal, this absolutely does not mean that the sun has entered its aging period!"

Hearing Ye Nangeng's words, a hint of bitterness flashed in Lü Yongchang's eyes.

That's how it was in my past life.

Everyone thought that these tiny changes in the sun's data were just a coincidence.

As a result, humanity lost two whole years to escape!
