Rebirth: Starting from Lighting Up the Tech Tree

The response from the Builders of Civilization took two whole months.

It's not a matter of distance. Quantum entanglement channels maintain zero latency even at 28,000 light-years. The reason for the wait is simple: the Builders are observing their Festival of Silence—a collective meditation period lasting three Earth months, during which all external communications are automatically cached.

Zuo Cheng did three things in the past two months. He refined the design parameters of the Star Sea from 830 meters to the interface specifications of each subsystem. He helped Zuo Weiyang learn to build a boat with building blocks, although that boat looked more like a crooked bridge. And he checked the blue light on the edge of the twelfth branch icon on the system panel every day.

The Blu-ray display remains unchanged. The recommended progress is stuck at one-third. The system note simply reads: "Waiting."

Yu Ying laughed out loud in her office when she received the automated reply. She turned her chair around to face Zuo Cheng, her eyes shining with a light she hadn't seen for two months.

"We're waiting impatiently. They're celebrating. Sometimes the gap between civilizations in the universe is more absurd than the gap in technology."

The moment the Silence Festival ended, the recommendation letter from the Builders Civilization arrived.

The letter's contents surprised everyone. It wasn't a few lines of solemn recommendation, but a poem of two hundred lines. The Builders civilization used poetry to record all formal inter-civilizational agreements. They believed poetry was an unalterable language, each line's rhythm and syllables forming a natural check code. Changing a single word would cause the entire poem's rhythm to collapse.

After translating the entire poem into Chinese, Tan Yue read it three times. The first 194 lines describe the Builders' civilization's 40 million-year history of construction. They built energy bridges between stars, communication channels between consciousness and matter, and orbital rings capable of holding an entire civilization. The last six lines suddenly stop. It's as if the Builders put down their tools for the first time, looked up, and saw a strange neighbor in the distance.

We build. We build bridges between stars and planets. We build conduits between consciousness and matter. But we have never built trust. Trust cannot be built. It can only be given. We give you trust. Use it to build a spaceship.

Tan Yue said it was the best letter of recommendation he had ever heard. Han Lu said it was the strangest official document she had ever seen. Yu Ying shook her head: "It's not an official document. It's a gift."

The builder also included a technical document in the appendix to the poem, showcasing their self-developed woven quantum repeater amplification technology, which can extend the effective coverage of quantum entanglement channels by three times. The document concluded: "You may need to contact people further away. This is for you. It's free. Our civilization doesn't need money."

Zuo Cheng looked at the words and his lips twitched slightly. A civilization 28,000 light-years away had sent a gift, with the note that it was free.

Second recommendation secured. One last one needed.

The Observer civilization's response came long after the Builder's. The letter had actually arrived long ago, but the Observer's language contained a dimension that humans couldn't directly perceive: emotional coloring. Every word carried a specific emotional tone, like tone and expression compressed into the text itself. The Web-based automatic translation system lagged for a full half-day.

Yu Ying and her team manually decoded the words. She drew a three-layer color spectrum model on the whiteboard, breaking down the emotional pigments of each word into frequency, intensity, and decay curves. Forty-seven words, each with three layers of meaning. When they reached the twelfth word, she said something that made everyone stop.

"They weren't writing letters. They were compressing an entire memory into a single sentence."

The translated recommendation letter consisted of only one sentence. But that sentence carried three layers of emotional weight.

The first layer is curiosity. The second layer is relief. The third layer is something that no human vocabulary can accurately describe. Yu Ying searched for a long time and finally found the closest word in Chinese: anticipation.

The observer's recommendation letter reads: "We've been watching. Watching for a long time. From your first heartbeat to your first broadcast. We never speak. Because the observer only watches and doesn't speak. Today is the first time the observer has spoken since its inception. For you. Recommendation."

A note at the end: We never make recommendations to others. Not because our standards are too high. It's because no one ever asks us. Thank you for asking.

The control center remained silent for a long time. Han Lu wiped her eyes with the back of her hand. Chen Hao stood in front of the projector, his lips moved but he didn't say anything.

Zuo Cheng projected the three letters side-by-side onto the wall. On the left were the listener's five lines. In the middle was the builder's two-hundred-line poem. On the right was the viewer's single sentence, conveying three layers of emotion. Three letters, three civilizations, none out of obligation. All stemmed from something deeper.

In his diary, he called it the basic goodwill between civilizations.

Zuo Cheng submitted three letters of recommendation to the home port.

The verification took less than forty-seven seconds. Shorter than a heartbeat.

Home Port Reply: Host of the 177th node of the Web, Human Civilization, joint recommendation verification passed. All three recommendation letters are valid. Now unlocking the core data of the twelfth branch.

The reply included a note from the founder's code: For the first time in the four billion years since the recommendation system was established, all three letters of recommendation were submitted within the same standard year. It is also the first time that none of the three letters were written out of obligation. The first expressed waiting. The second expressed trust. The third expressed expectation. These three together represent everything worth passing on between civilizations.

The system panel updates automatically. The twelfth branch icon changes from gray to dark blue, indicating it's in budding preparation mode. All four prerequisites are marked as met. The system notification states that the twelfth branch's core data packet has been transferred from the home port to the Blue Star origin node; it is approximately forty-seven exabytes in size, seven hundred times the size of the eleventh branch's core data.

The data package contains the complete quantum field-driven scheme of the first-generation civilization, engineering blueprints for the inertial isolation chamber, the physical theoretical framework for the weaving of a consciousness network, and an encrypted file. Filename: For the first successor of the twelfth branch.

The system notes appeared at the bottom of the panel, and Zuo Cheng read them word by word.

This data packet has been stored in the home port for five billion years. It's waiting for you. Not waiting for humanity. It's waiting for you. Because the condition for activating the twelfth branch isn't what you've achieved. It's what another civilization has chosen for you.

Zuo Cheng closed the panel. He opened the outermost index of the data package. The first item in the index was not a technical document.

This is a warning.

Activating the twelfth branch will bring about an irreversible change. It will permanently bind the activator's consciousness to the Web's core. The activator's will will become the central processor of the Web's consciousness network. The activator will be able to perceive the real-time status of all 177 nodes. The activator will become the de facto coordinator of the Web civilization community.

The price: You will no longer be an individual. You will be a web.

Zuo Cheng turned off the index. The panel returned to standby mode. The blue standby light flickered in the darkness.

It's not in a hurry. It has been waiting for five billion years.

Zuo Cheng wrote the only line of text for today in his diary.

A net. Not an isolated person. Am I ready?
