Introduction to science fiction time travel novels In 2026, seven top academics mistakenly entered a mysterious room deep in the university. Out of curiosity, they used acupuncture needles to touch the bronze acupuncture figurines. However, they coincided with thunderstorms and meteor showers, and were involved in the emergency space-time agreement of the alien AI "Tianji" in the early years of Zhenguan, which was in parallel time and space. The spaceship is hidden deep in the Zhongnan Mountains, with only 5.7% Of its energy remaining. The AI ​​in the cloud has become "scrap iron" waiting to be recharged, while the AR glasses and laptops carried by the seven people have become the only technological fire that spans thousands of years. There are no cheating superpowers, only the knowledge barriers of their respective professions - AI engineers are in charge of Tianji operation and maintenance, business elites coordinate the realization of resources, mechanical experts build industrial prototypes, medical students build medical systems, agriculturists improve crops, physicists crack the principles, and new energy experts tackle difficult problems. Using Mojing Academy as a springboard, they used activated carbon to purify refined salt and decolorized brown sugar to earn their first pot of gold. They used voltaic piles made of copper coins to keep Tianji alive, and quietly planted the seeds of the industrial revolution in the soil of farming civilization. The collision of alien technology and the customs of the Tang Dynasty, the interweaving of hard-core technology and survival wisdom, they not only have to deal with government investigations and Hushang games, but also solve the energy dilemma and promote technological iteration. Tianji energy gradually recovers, unlocking not only heavy industry blueprints and interstellar databases, but also the ultimate choice of returning to modernity and rebuilding civilization. This is not a cool story about a solo counterattack, but a hard-core time travel with teamwork. Every technological breakthrough is down-to-earth, and every collision between civilizations is thrilling.
