This month, Zhang Fan was very surprised.

Although he still couldn't beat Bob, Bob very willingly handed over all the food from the automated restaurant to him.

Zhang Fan was flattered and grateful, and wanted to share half of his food with Bob, but Bob firmly refused and obediently went back to eating his own biscuit.

Bob thought to himself: I would never eat food grown from alien corpses.

The biscuits are made from the previous season's crops. Once the current season's crops have absorbed the "fertilizer," the next season's crops will resume normal nutrient levels. At that point, Bob will resume his competition for food with him.

Zhang Fan didn't think too much about it, happily finished her dinner, and happily went back to her room to sleep.

In a dream.

Silicon-based...carbon-based civilization...memory inheritance...the transfer of knowledge between different individuals...the material transmission of knowledge...memory absorption...knowledge inheritance...

When Zhang Fan woke up in the morning, he felt extremely overwhelmed.

Lately, he's been having strange dreams about a place called "Silicon-based Civilization." Strangely, he can understand the so-called silicon-based language in his dreams.

He dreamt that he was a soldier, different kinds of soldiers, that he was born, grew up, studied, lived, and enlisted there...

Every morning when Zhang Fan wakes up, he feels like his mind is a mess and he has a headache. Only by reading books and constantly studying can he feel a little better.

After reading all the books on the shelves in the lounge, Zhang Fan began frantically searching for every book he could find at the "Bird's Nest" base, including all the operation manuals he could find, and even unrelated food labels and instructions.

Zhang Fan felt he had never been so eager for knowledge. After he had sifted through everything with text in the "Bird's Nest" base, he began to turn his attention to the main computer of the "Bird's Nest".

The main computer in the "Bird's Nest" is the brain of the entire base, and its designers call it the "Phoenix".

"Phoenix" not only stores all the data from the Bird's Nest base, but also all the knowledge, technology, culture, music, and philosophy of human civilization to date...

Phoenix is ​​also a highly intelligent AI. It can even "memorize" the user's input and update itself, thus achieving a state similar to "self-evolution".

"Access restrictions prevent data reading."

Well?

Zhang Fan was somewhat surprised that he couldn't read the "Phoenix" database even with Professor Su Muran's access privileges.

A row of 25 boxes pops up on the main screen, indicating that a 25-digit password is required.

Zhang Fan was unaware that the "Phoenix" database possessed the highest level of confidentiality, which even its designers could not crack.

Why can't this password be cracked?

Because no one knows what the password is. The 25-digit password is divided into 5 groups of 5 digits each and stored in the National Security Center of the five permanent members of the United Nations Security Council, which designed and built the "Bird's Nest" Mars base.

In other words, each country owner only knows five of the 25-digit code. Even these five digits are not limited to using their own country's numbers or characters.

The code could be any script or dialect on Earth, or even hieroglyphs from an unknown tribe in the Amazon rainforest.

Scientists have made calculations.

Even if the world's fastest supercomputer, the Galaxy III, were to work day and night to crack this code, it would take a million years!

Zhang Fan glanced at it and then issued an instruction to "Phoenix": "Use the 'Silicon-based Two-Dimensional Sequence Combination Model' to calculate the password."

The meaning is unclear, and the instruction cannot be recognized.

"Switch to manual input".

Zhang Fan quickly programmed on the computer using the keyboard, and after completing the mathematical model, he pressed the Enter key.

"Phoenix" began to automatically perform calculations according to the model program input by Zhang Fan.

A few minutes later...

"Password correct."

"Unofficial astronaut Zhang Fan has received the highest authorization."

"Start reading the database."

Zhang Fan opened the "Phoenix" digital library.

Which books should I read first?

Zhang Fan first searched for books related to the field of space science. Even so, the catalog of books starting with the A category had hundreds of pages.

Let's start from the first page.

Introduction to Aerospace Technology, Introduction to Interstellar Navigation, Aerospace Mechanical Engineering and Automation, Flight Dynamics of Long-Range Rockets, Fundamentals of Solid Rocket Engine Combustion, Heat Transfer of Solid Rocket Engines, You Can't See Me Haha, Theoretical Foundations of Rocket Engines, Launch Vehicle Design and Manufacturing, Principles of Aerodynamics, Research on Ballistic Measurement and Trajectory Reconstruction Technology, Variable Center of Mass Control Technology and Glide Slide Trajectory Optimization for Ballistic Missiles, Introduction to Aviation...

Zhang Fan thought to himself, "I'll finish reading these books today."

You read that right, he's going to read all of these books in one day!

If the leaders of the five permanent members of the UN Security Council on Earth knew that Zhang Fan cracked the code and obtained the highest authorization simply to read a book, they would definitely want to kill him...

As Zhang Fan read further, he discovered many errors in the book.

Is the area of ​​a circle S = πr²?

That's not right. If you unfold the circle in four-dimensional space, this formula is wrong.

Also, the mathematical constant π can only be taken up to 2 trillion decimal places now.

The accuracy is ridiculously low! What's the difference between this and driving with your eyes closed during interstellar travel?!

Left with no other choice, Zhang Fan could only take a pen and a blank sheet of paper and take notes while reading the book to correct the errors.

...

Human survival point.

The one hour in the evening is, as usual, prime time to watch Mars TV live.

The way Zhang Fan diligently studied and took notes was soothing to everyone.

Wow, they're studying so hard even in a place like that!

"Ugh, stop talking. Compared to Zhang Dada, I'm so ashamed."

"A top student isn't scary; what's scary is when a top student works even harder than you!"

"And he's even more handsome than you!"

"A man who is serious is so handsome!"

"Zhang Dada is so incredibly handsome!"

"Uh-huh!"

Those around him, especially the young women, nodded in agreement.

Every night after finishing his reading, Zhang Fan would take his notes to "Phoenix" to verify each item.

"Verification 1: Correct the accurate value of the constant c (speed of light) in the mass-energy equivalence equation E=mc2."

Please provide a proof or data model.

Zhang Fan began typing the process of evaluating the constant c and its related mathematical model onto the screen, and finally pressed Enter.

"Start verification."

The proof process has been verified to be error-free.

The accurate value of the constant c in the mass-energy equivalence equation E=mc² has been corrected.

The system detected that there are a total of 10 records in the database containing the constant 'c'. Should all records be corrected?

"yes."

The database has been fully corrected.

"Verification 2..."

Unfortunately, Zhang Fan's nightly calculations with "Phoenix" were after the live broadcast time, otherwise the physicists on Earth would go crazy if they saw it.

...

Wano Country, the human survival point in Kyoto.

Kazuo Yasuda turned off the television after the live broadcast ended.

"Madam, how is the situation at the school now?"

“Darling, my temporary school is back on track. We usually play videos of Zhang Fan studying during self-study time, and the effect is excellent. The school has launched a ‘mass learning’ campaign, and the children are studying even harder than before the New Era. I see the hope for the future of humanity in these children!”

"That's good." Kazuo Yasuda nodded with satisfaction.

“Sigh.” Mrs. Kang Tian’s tone changed. “Zhang Fan is a role model for all mankind, but he is all alone on Mars. He is really pitiful. He doesn’t even have anyone to talk to.”

"That won't be the case for long."

"Hmm? Darling, what do you mean?"

"I learned at the Cabinet meeting held at the Ministry of Foreign Affairs today that our country's 'Vulcan' Mars probe, launched two months into the new era..."

"It will reach Mars orbit tomorrow."
