Are you graduated from the astronomy department?

There was bitterness all over Lü Yongchang's eyes. He slowly shook his head and said, "Old Ye, I've seen the data in the paper."

"I'm not very optimistic about the sun's prospects."

"In my opinion, we need to give some serious thought to... the issue of the survival of human civilization."

Ye Nangeng, who was walking ahead, suddenly stopped in his tracks.

He turned around and looked at Lü Yongchang with a frown. "Professor Lü... don't you think these words are a bit too..."

Ye Nangeng didn't finish his sentence.

But Lü Yongchang understood what he meant.

It was nothing more than words like being overly worried or exaggerating the facts.

He wasn't angry.

On the contrary, he even felt a bit sad and helpless.

The technological level of humanity was really too low!

But at this moment, Lü Yongchang didn't argue with Old Ye.

Without conclusive evidence, no one would believe anything he said.

So, he said in a calm tone, "Old Ye, whether it's true or not, let's wait until I get the observational data and make calculations before we talk."

"I also hope that I made a wrong calculation."

Ye Nangeng's brows knitted tightly. He gave Lü Yongchang a meaningful look and said, "Fine, I'll take you to the observatory right now!"

...

At the observatory of the National Astronomical Observatories of China.

A huge astronomical telescope was placed in the center.

"Hello, Old Ye!"

As soon as they entered the observatory, a researcher greeted Ye Nangeng respectfully.

Old Ye nodded with a smile and said, "Xiao Wang, point the telescope at the sun."

"And show Professor Lü the observational data from a few days ago."

The researcher called Xiao Wang was slightly startled and turned his head to look at Lü Yongchang.

Gradually, his eyes widened more and more.

"You... you're Professor Lü Yongchang?!"

"Professor Lü, you're my idol!"

"No, no, no! You're my fan... Oops! I mean I'm your fan!"

Xiao Wang looked at Lü Yongchang excitedly, speaking incoherently. "Professor Lü, can, can you sign for me?!"

Lü Yongchang: "???"

Ye Nangeng: "???"

Apparently, Old Ye didn't expect this situation either. He glared at the researcher in embarrassment. "Ahem! Xiao Wang! Let's talk about the signature later. Finish the research task first!"

A trace of grievance flashed across Xiao Wang's face. He walked towards the console with a sullen face.

Seeing this, Lü Yongchang couldn't help but laugh. "Don't worry, I won't forget about the signature!"

Hearing this, a flash of excitement appeared in Xiao Wang's eyes, and his steps became brisk as he walked.

Old Ye looked at Lü Yongchang, who was smiling beside him, with a hint of envy. "Professor Lü, you're really popular!"

"Look at Xiao Wang. He's like one of your researchers!"

"I even suspect that if you say the word, he'll switch to your side!"

Facing Old Ye's envy, Lü Yongchang could only spread his hands with a smile to show his helplessness.

...

It didn't take long before Xiao Wang came to Lü Yongchang with a stack of documents.

"Professor Lü, these are the solar observational data from the past month!"

"Look... do you need more?"

"It might take some time to retrieve data from more than a month ago, but..."

Xiao Wang's enthusiasm exceeded Lü Yongchang's expectations. He waved his hand with a bitter smile. "Ahem... no need, no need."

"A month's data is enough."

A clear look of disappointment flashed in Xiao Wang's eyes. "All right."

"Then, Professor Lü, call me if you need anything!"

Lü Yongchang nodded with a bitter smile.

He never expected that he could experience the treatment of a "star".

After Xiao Wang left, Lü Yongchang took a deep breath and looked at the documents in front of him with a solemn expression.

Seeing this, Old Ye's eyebrows twitched slightly.

He was a bit skeptical whether Lü Yongchang could understand these highly professional data!

"These data... have problems."

Lü Yongchang said in a serious and low voice.

"Oh? What kind of problems?" Old Ye casually moved closer to Lü Yongchang and asked.

"Look, the magnetic field strength. Starting from half a month ago, the sun's magnetic field strength has increased significantly!"

"Besides, there are also problems with these other data!"

As he spoke, Lü Yongchang pointed at the documents in front of him. "If I'm not mistaken, solar flare activities should have been more frequent during this period, right?"

A trace of shock flashed in Old Ye's eyes.

In just a few minutes, among so much data, Lü Yongchang not only pointed out several problematic data items but also accurately judged the current situation of the sun!

This ability...

"Professor Lü, are you... graduated from the astronomy department?"

Ye Nangeng looked at Lü Yongchang in front of him in disbelief and blurted out subconsciously.

Lü Yongchang was slightly startled, then shook his head with a smile. "Old Ye, I'm from the Physics Department of Sandaokou University. Currently... I haven't really graduated yet. The graduation certificate hasn't been issued."

This was true.

Some time ago, because he was busy with the matter of Pangu - 1, he had no time to go to Sandaokou University to get his graduation certificate.

Old Ye swallowed slightly and looked at Lü Yongchang in disbelief. "Then how did you..."

"Self - taught. I taught myself everything!"

Lü Yongchang made a joke to get past the question.

"Incredible!" Ye Nangeng's eyes widened like bells. He murmured to himself, "I've never seen anyone like you!"

"Ahem!"

To prevent Old Ye from continuing to marvel, Lü Yongchang coughed softly. "Old Ye, do you have any draft paper here?"

"I need to check some things."

Old Ye nodded in amazement and took a few blank A4 papers from the side. "Are these enough?"

Lü Yongchang took the A4 papers, took out his pen from his pocket, and nodded. "Enough, enough!"

As he spoke, he sat on the chair and quickly wrote an equation on the A4 paper.

Ye Nangeng hurriedly leaned over and stared intently at Lü Yongchang's handwriting.

At first, Ye Nangeng could follow Lü Yongchang's train of thought.

But after a few minutes.

Ye Nangeng looked up with a confused expression and glanced at Lü Yongchang, who was writing furiously, with a lack of confidence.

Was his ability too low?

That shouldn't be the case!

He had some confidence in his math skills.

Although he couldn't handle those difficult problems in the history of mathematics, solving some astronomy - related problems was easy for him.

But now...

He just couldn't understand the change process of Lü Yongchang's series of equations!

At this moment, he couldn't help but think of his college days.

The fear of being dominated by advanced mathematics!

...

Half an hour later.

Lü Yongchang let out a deep sigh and put down the pen in his hand with a solemn expression.

"How is it?"

Unconsciously, Old Ye's attitude towards Lü Yongchang had changed a great deal. "Is there any result?"
