When the doorbell rang, Chen Hao was stuffing the last piece of watermelon into his mouth.

He looked up, a melon seed still in his mouth, and saw Susan move from the sofa to the coffee table. Carl was staring toward the door, and Nana had already stood up.

"Who is it?" he mumbled, nearly dropping the watermelon from his mouth.

No one answered. The doorbell rang again, this time more urgently.

He wiped his mouth and got up to open the door. Three or four people stood outside, holding notebooks and recorders, with video cameras slung over their shoulders. The woman in front handed him the microphone: "Are you Chen Hao? We are reporters from the city TV station and Science Weekly, and we'd like to interview you about your extraterrestrial experiences."

Chen Hao stood frozen at the door, his hand still gripping the doorknob.

He glanced back at the living room. Susan sat up straighter, and Carl quietly took a half-step closer to her. Nana stood still, her eyes flickering slightly—a signal that she was accessing the database.

"Now?" he asked.

"The sooner the better," the reporter said. "The whole city is waiting for this story."

He took a deep breath and stepped aside to make way.

A group of people filed in, greeting each other and setting up equipment and wiring. One male reporter almost tripped over a tilted coat rack and had to grab it to steady himself.

"This place... is quite lively," he muttered.

“The floor was just mopped,” Nana said calmly. “The cleaning process isn’t fully optimized yet.”

The reporters laughed, and the atmosphere eased a bit.

The camera was set up, the lights were turned on, and Chen Hao was seated in the main seat. He sat on the sofa, his hands on his knees, his fingers unconsciously rubbing together.

"Hello everyone," he began, his voice a little dry. "I'm not an expert, nor a scientist. I used to cheat on exams whenever possible, never using my brain. I failed advanced mathematics three times, and I would get a stitch in my side when running 800 meters in PE class."

Laughter broke out in the room again.

“But that trip was real,” he continued. “We went to a planet that nobody knew about. The sky there was purple, and it glowed at night, like someone had sprinkled fluorescent powder on it. The water was sweet, the grass grew taller than a person, and when the wind blew, the whole field moved, like it was breathing.”

Susan chimed in, "The air there is so refreshing. Unlike Earth, which always has this indescribable smell. It was the first time I felt my lungs were clean there."

Carl nodded: "The gravity is low, walking feels like floating. I fell once, rolled twenty meters before stopping, and it didn't hurt at all."

The reporters jotted down notes quickly.

Nana suddenly spoke up: "The atmospheric oxygen content is 28.3%, nitrogen accounts for 67.1%, and there are trace amounts of helium and unknown inert gases. The average daily temperature is 21.5 degrees Celsius, and the temperature difference between day and night does not exceed three degrees. Such an environment is extremely rare among known celestial bodies."

A moment of silence.

"Are you reciting your lessons?" Chen Hao turned to look at her.

"State the facts."

"Don't use such strong words, they won't understand."

“It can be converted.” Nana paused. “It’s like sleeping in spring every day and breathing oxygen with mint added.”

Even the cameraman laughed this time.

The interview continues.

They talked about how the spaceship started, how they traveled through the wormhole, and how they huddled together to sleep on their first night on the strange planet because it was so dark that no one dared to move. They also talked about how Nana suddenly sat up in the middle of the night saying, "An abnormal heartbeat has been detected," when it turned out that Chen Hao's snoring had startled her.

The atmosphere became increasingly relaxed.

Until a reporter wearing glasses raised his hand to ask a question.

"Are you hiding anything?" he asked. "Like resource conflicts? Internal contradictions? Or... is that planet actually not friendly?"

The laughter stopped.

Everyone looked at Chen Hao.

He didn't answer immediately, but turned to look at Susan, then at Carl, and finally at Nana.

Nana nodded gently.

“There is a conflict,” Chen Hao said.

The reporter's eyes lit up.

"The biggest time was the first time Nana mopped the floor at home."

Everyone was taken aback.

"She was moving too much, water was spilled everywhere, chairs tipped over, vases almost broke, and my dad almost slipped. Our whole family was cleaning the floor that afternoon."

Laughter erupted in the room.

“But we didn’t argue,” he continued. “Nobody blamed her. Because she didn’t do it on purpose, she just wanted to help. Just like on that planet, everyone was facing those things for the first time. Fear, mistakes, messing up, but nobody wanted to hurt anyone.”

He paused.

"What we brought back wasn't a secret, it was proof. Proof that even a group of ordinary people could travel that far and return safely."

The reporters were silent for a few seconds, then some began to applaud.

The next questions were much milder.

They asked what creatures they saw, what food they ate, and whether they discovered any relics of civilization.

Carl said seriously, "There's a kind of bug with six legs that glows and leaves a silver trail wherever it crawls. We call it a 'ground lamp'."

Susan added, "You don't need to turn on a flashlight at night, just follow them."

Nana pulled up a simulated video and projected it on the wall: a purple land with silver glitter flowing like a river flowing through the grassland.

“This is a scene reconstructed from memory,” she said. “The real scene is even more beautiful.”

"Then why didn't you release him sooner?" the reporter asked.

“Because,” Chen Hao interjected, “she said she wanted to save electricity.”

Nana said expressionlessly, "Household electricity usage needs to be allocated reasonably."

Everyone laughed so hard they were doubled over.

The interview lasted for over an hour. The last question came from the female reporter.

"If you had another chance, would you still go?"

Chen Hao didn't say anything.

Susan looked down at her hands. Carl gazed out the window. Nana's system hummed softly, as if calculating an answer.

"Yes," Chen Hao said, "but we need to fix the house first."

He pointed to the shoe cabinet that had been knocked askew.

Amid laughter, the reporters packed up their things and prepared to leave.

The cameraman glanced back before leaving and said, "You guys don't look like heroes at all."

“We weren’t like that to begin with,” Chen Hao said. “We’re just ordinary people who were a bit luckier.”

After the door closed, the room became quiet.

Chen Hao leaned back and lay down on the sofa.

"I'm exhausted."

Susan handed her a glass of water.

"You're right."

Carl said, "They laughed when you used the word 'spring'."

After scanning the last recording, Nana said, "Public sentiment feedback analysis complete. Positive feedback accounted for 87.6%, reaching the safe threshold for dissemination."

Chen Hao didn't move, his eyes were closed.

After a while, he suddenly opened his eyes and looked at the calendar on the wall.

It was taken down yesterday, but it's been re-hung today. It's slightly off-center, but still in its original position.

He smiled.

The night outside the window was deep, and the streetlights in the distant community stretched out in a line, like a silver river laid out on the ground.

Susan walked to the window and placed her hand on the glass.

She looked at the lights for a while.

Then she turned and walked toward the door.

"I'm going for a walk outside."
