Industrial Time Travel: I Am a Hanger-On by Li Bai's Side

In 740 AD, outside Jianmen Pass, a metallurgical engineer from 2026 opened his eyes. Gu Yunzhou, a Ph. D. From the Institute of Metal Research, Chinese Academy of Sciences in Shenyang, had just stayed up all night in the laboratory before traveling through time. With a head full of materials science, smelting technology and modern knowledge, he landed in the prosperous Kaiyuan era of the Tang Dynasty - penniless, stumbling on the language, and the first person he met was named Li Bai. This is not a story about "helping poets to rise to prominence". Li Bai did not need his help and did not care about fame. He just became interested in this young man who spoke strangely and knew the "iron-making recipe", and casually accepted him into his team of hangers-on. From then on, a 40-year-old poet and a 28-year-old engineer traveled together in the last golden age of the Tang Dynasty. Gu Yunzhou has no system and no golden fingers. What he has is the rigorous mind of an engineering doctorate and a clear understanding of the direction of history: the Anshi Rebellion is still fifteen years away. A span of six seasons, forty-two years. From Jiannan Shu Road to Chang'an Wine Shop, from Luoyang Iron Factory to Anshi Fenghuo, Gu Yunzhou took root in the troubled times step by step - not relying on poetry, but relying on charcoal, iron, coking coal and a set of smelting techniques that slowly changed the times. And Li Bai was always the one who walked in front of him and kept pushing him further. This is an industrial flow time travel, and it is also a true historical friendship. There is no dimension reduction attack, just people from two eras walking on the same road and changing each other.
