After completing today's learning content, Zhang Fan planned to work with "Phoenix" to verify his notes. Upon returning to the main control room...

He noticed a red light flashing on the control panel on the right.

Hmm? What kind of light is this? I hadn't noticed it before.

Zhang Fan sat down there, filled a glass of water from the water dispenser next to him, and casually pressed the button next to the red light.

drop--

When the red light goes out, the communication system automatically projects the image onto the large screen in the main control room.

puff--

Zhang Fan spat out a mouthful of water.

"No Lu Xi... Dao Su Lu... Ya Da... Da Mai... Ha Ya Ku..."

What... what's going on? So you can watch movies here after all?

Zhang Fan was shocked. "Why didn't I notice sooner!"

Seriously?

Is this really that exciting? Which astronaut forgot to take this personal treasure with them?

Looking at the background in the picture, it seems to be a place like a spaceship.

Are astronauts this professional even when watching a film? It's a shame we haven't seen the male lead appear yet.

Zhang Fan swallowed hard, his blood rushing to his head, sweat beading on his forehead—it was hot.

So he took off all his clothes. Anyway, he was the only one at the "Bird's Nest" base, and he was the only male animal in the entire solar system besides Bob, so no one would see him running around naked.

The girl in the picture has opened her eyes.

The two looked at each other.

The image freezes.

The girl's eyes widened...

"Wow—" the girl in the video exclaimed, then rattled off a string of words. Zhang Fan could tell it was in a foreign language, but he didn't know what it was saying.

"Oh ho ho! Let's die in this pot!"

What? He didn't even put Chinese subtitles on it. This guy's movie selection is terrible.

"Dance of the opera..."

This plot is no good. There's too much dialogue and it's too wordy. Why aren't we getting to the main story yet?

"Ah... Damn it." The girl in the video slapped her forehead, finally remembering to turn on the simultaneous interpretation system.

I've already taken my pants off, and this is what you show me?

"Hello, hello, can you hear me?" The girl in the video waved to Zhang Fan as she spoke.

puff--

Zhang Fan spat out another mouthful of water.

Real-time communication? Isn't this a movie?

In his excitement, Zhang Fan stood up. As he stood up, the camera lens moved downwards.

"ah!!!"

In the other scene, the girl quickly covered her face.

"Wow!!!"

The girl finally remembered she wasn't wearing any clothes and quickly left the screen. Zhang Fan hurriedly put on his work clothes.

About 10 minutes later, the two reappeared on the communication screen, sitting upright, looking serious and with red faces.

A girl doesn't need 10 minutes to get dressed, but she needs more time to calm down.

"Hey, hey, is your air conditioner broken too?" Yui Ishihara spoke first.

"What air conditioner?" Zhang Fan didn't quite understand what the other person meant.

"My air conditioner's mainboard burned out, so it can't cool down. It's very hot here." Through the girl's explanation, Zhang Fan finally understood that she wasn't wearing clothes because she was hot.

"It's 30 degrees Celsius here. Is it hot where you are too?"

"Yes, yes." Zhang Fan nodded quickly, then guiltily turned up the air conditioner temperature a few degrees.

"Okay." The girl nodded in understanding, her tone becoming much more relaxed. "Are you alone over there too?"

"Yes." Zhang Fan nodded. The fact that the other person asked this meant that she was also alone and not inside the "Bird's Nest." "Where are you?"

"I'm on the 'Vulcan', what about you?"

"I'm at the 'Bird's Nest' Mars base, Vulcan? Where is that?"

Through the girl's explanation, Zhang Fan finally understood her situation.

The Soyuz Joint Mars Space Station is located in orbit 500 kilometers above the Martian surface and is the most important and only Mars space station for Earth's exploration of Mars.

The Soyuz spacecraft was built earlier than Tiangong. At that time, no single country could afford the enormous cost of building a space station on Mars. Therefore, the Soyuz spacecraft was jointly built by major spacefaring nations such as China, the United States, Russia, Japan, and Europe. Other countries also participated in the funding and were authorized to use it.

"My name is Ishihara Yui. What is your name, sir?"

"My name is Zhang Fan."

"Mr. Zhang Fan, I'm so happy right now." Ishihara Yui's eyelashes fluttered, and her eyes became misty, clearly on the verge of tears. "I thought I was the only person left in the world, 555... Waaah..."

"Calm down, Ms. Ishihara, calm down." Zhang Fan saw that she seemed about to cry endlessly, so he had no choice but to try to comfort her, after all, they were the only two humans left in the solar system.

"I'm sorry, Mr. Zhang Fan, you can just call me Yui. I'm so excited, it's been so long since anyone has spoken to me." Yui Ishihara wiped away her tears and began to confide in Zhang Fan about her current predicament.

“Okay, Yui, I understand now,” Zhang Fan said. “Let me see the malfunction interface of the ‘Vulcan’.”

"Okay, I see. Now do as I say."

Following Zhang Fan's step-by-step instructions, Ishihara Yui disassembled the air conditioning mainboard of the "Vulcan". The mainboard had a hole the size of an egg burned in the middle, which could not be repaired.

It's too hot to stay here.

Following Zhang Fan's guidance, Ishihara Yui finally opened the connecting hatch between the "Vulcan" and the "Soyuz" and transferred to the space station.

"Thank you, Mr. Zhang Fan." Ishihara Yui was moved to tears.

The Soyuz Joint Space Station on Mars is enormous, with a total mass of 623 tons. It is used as a transit station for human landings on Mars and has very comprehensive internal modules.

However, for Yui Ishihara alone, this place was too big and too empty. She began to feel the terror of deep space phobia, so she could only try to find something to talk about with her only support to dispel her loneliness.

"Mr. Zhang Fan, what are you doing?"

“I’m working with ‘Xiaofeng’ to verify some theorems.”

"Xiaofeng? Do you have other girls with you?"

“No, oh! This ‘Little Phoenix’…” Zhang Fan finally managed to explain that “Little Phoenix” was his name for “Phoenix,” the brain of the “Bird’s Nest” Mars base.

"What do you need to verify?" Ishihara Yui nodded, relieved.

"For example, the value of the speed of light c in the mass-energy equivalence equation E=mc2. In this equation, the speed of light is a constant, but according to the definition of silicon-based physics, the speed of light is a variable."

"Huh?" Yui Ishihara said she didn't understand.

"For example, the speed of light is different in different media, right?" Zhang Fan explained patiently.

“But I seem to remember my teacher teaching me that in high school, the speed of light is the speed at which light travels in a vacuum, right?” Yui Ishihara replied.

Don't you think this question itself is a paradox?

"What's the meaning?"

"Because light cannot propagate in a vacuum, when a photon enters a vacuum, it is no longer a vacuum."

"Ah..." Yui Ishihara's eyes widened, feeling that it made sense yet also didn't, but she didn't know how to refute it. This was beyond her knowledge.

"Alright, Yui, you should go and get some rest." Zhang Fan said, closing his notebook. "The temperature will drop when the Soyuz spacecraft reaches the dark side of Mars, so remember to cover yourself with a blanket."

"Okay, goodnight Mr. Zhang Fan." The girl felt a warm feeling in her heart.

Goodnight, Yui.

"Uh, that..."

"What?"

"Mr. Zhang Fan, did you hear what I said before when I pleaded for help?"

"What did you say?"

"That's what I swore I would say..."

"No, Yui, what did you swear you said?"

"That's all, goodnight Mr. Zhang Fan."

Goodnight, Yui.
