Rebirth: Starting from Lighting Up the Tech Tree

Shen Yiming finished writing the last entry of his diary in the convalescent room at the home port. It wasn't that he couldn't write anymore; he felt he had enough. Outside the window, the quantum light stream of the home port was slowly turning for what seemed like its umpteenth time today. When he put down his pen, his hand was steady, just as steady as when he signed his name at the end of his diary every time over the decades.

After writing the last word, he didn't immediately close the log panel. Instead, he flipped through everything he had written before. He couldn't remember the date of the first entry, but he remembered that when he sat in the communications pod that day, the solar system was visible outside the window, and there were six people inside. He wrote the first line. From that day on, every entry began with the same word. Not intentionally, but out of habit. Later, "Today" became his signature, not at the end, but at the beginning. For decades, every "Today" he sat in the same chair, facing the same window, and wrote the same opening sentence.

He encountered Ji Beihang in the corridor this morning. Ji Beihang had just disembarked from his solo flight vehicle and was walking extremely slowly. It wasn't that he was too old to walk; he was using his feet to sense the incredibly faint quantum light flow vibrations emanating from the mothership floor. Decades of flying had etched countless manual orbital insertion postures into the soles of Ji Beihang's feet, each step a soft landing with an error of less than twenty meters. Now he no longer flies, but his feet remember. He didn't stop as he passed Shen Yiming, merely glancing at him sideways; the two exchanged a very brief look. It wasn't a conversation, but a confirmation. They were both still there.

In his final entry in his diary, Shen Yiming wrote a passage about Ji Beihang. He said that a man who had flown his entire life learned to walk on his own two feet after retiring. He no longer needed to fly, but his feet still retained the postures of countless manual landings, each step a soft landing with an error of less than twenty meters. Not in the sky, but in the corridor. After finishing this passage, he paused for a moment, thinking if there was anything else he wanted to add. No. Everything that needed to be said had already been said in the previous entries. The last entry didn't need many words, just a gesture of closure.

While writing this final entry in his journal, he noticed something he had never seriously considered before. At the end of each entry, he had left a typo for Zuo Weiyang. Not a mistake, but something he deliberately included. He knew Zuo Weiyang would collect these typos in the central journal, putting them one by one into her empty room to digest and absorb. He had asked her last time how much space was left in her room, and she had replied that it was almost full. But Shen Yiming felt that room would never be full, because it wasn't a room, but her own heart. A heart cannot be filled with words; words only make a heart grow larger.

The misspelling he left today was different from before. It wasn't a miswritten homophone, but a stroke. A strange character form that had never appeared in his journal's language, a stroke structure never used by any web-weaving civilization. It wasn't a code, it was a trust. If anyone saw this stroke in this old journal system later, they would know it was the last one. He wrote the stroke very lightly, almost imperceptibly. But Zuo Weiyang would recognize it. She always could.

As he finished writing the last word of his final journal entry, a message from the Starship appeared on his communication panel. It was written by Jian Ning.

She said she heard he had finished writing his last log. She was on duty in the communications cabin today and read the log again from beginning to end. The first word of each one was "Today." Not a calendar, but every single day he sat in the same chair, facing the same window, writing the same sentence. She said she wrote one today too. As usual. The first word was also "Today." His "Today" and her "Today" were separated by decades, but the timeline was connected. The log wasn't for recording voyages; it was for saying that tomorrow would be the same as today.

Shen Yiming read the message but didn't reply. He put down the communication panel and glanced at the light trails of the home port outside the window. He typed one word in the communication bar and then deleted it. It wasn't that he didn't want to reply; he felt he didn't need to. Jian Ning already understood.

A few days later, Zuo Weiyang wrote a line about Shen Yiming in the Central Government's log. She said the retirement log wasn't Uncle Shen's retirement, but the log itself. He finished writing. Not stopping, but handing over. The recipient wasn't the next person, but everyone who would write "Today" at the beginning of any log entry. He spent most of his life doing one thing: saying "Today" at the beginning of each day's log, followed by "The journey continues as usual." From then on, every recorder would write "Today as usual" in any text they wrote to the Central Government, if nothing major happened that day. The copyright of those four words belonged to Shen Yiming. It wasn't a patent, it was a tradition.

As Shen Yiming sat down by the window of the recuperation room at the home port, he saw Jian Ning's latest log entry. The first line in the log system's recently active list was her sentence: "Today's flight path is normal." The rainbow halo outside the window had shifted by a fraction of a degree, exactly the same as on the last voyage.

He finished reading that line, then lowered his head and picked up the electronic pen on the table. The pen tip hovered near the last line of the last page of the log panel. He paused for a few seconds, watching the lights of the home port outside the window circle again and again. The beginning and the end are in the same place; a circle has no end, as Ji Beihang had said.

He put down his pen.

I'm not writing anymore. This is the last one. To be recorded.

Outside the window, the quantum light stream of the home port is spinning. The last word of the journal has been written. Not a period, but a stroke he deliberately left, a mark that doesn't belong to any language, a trace that can never be decoded but can always be recognized. It means nothing, but it signifies that there was a person here, and that he finished writing.

That evening, Zuo Weiyang read Shen Yiming's last entry in the access room. She didn't write anything extra in the central log. She traced an arc along the edge of the paper with her fingertip, resembling the shape of that stroke. She whispered a sentence, so softly that only she and the wind outside the window could hear it.

She said she received it. The last word wasn't the content, it was the warmth. The warmth of the pen tip. It was still warm.

She closed the journal panel. A breeze from Hangzhou slipped in through the window cracks, brushing against her face, neither too hot nor too cold. She took a deep breath, then reached out and opened the window a little wider. The wind blew in, carrying the unique coolness of a late spring evening and the scent of new leaves. She leaned back in her chair and closed her eyes.

Today is the same as always. Tomorrow will be the same too. A new diary will begin each morning, a new "today" will be written down, and a new hand will hold the old pen. It's not the same person, but the warmth of the handwriting is connected.

She opened her eyes and glanced at the old voyage log manuscript on the table. The first page was written in Shen Yiming's handwriting, neat and precise with accurate punctuation. She reached out and touched the edge of the paper. The paper was yellowed, but the writing hadn't faded. She closed the log and put it back on the bookshelf.

Outside the window, the lights of the home port have circled countless times today. No one counts, and there's no need to. The circle has no end. The log has no last line, because every "today" is the first line of a new log. Today, the course remains the same. Everything remains the same.
