ChangAn YanHuo: An (initially) Historical Progression Fantasy Saga

This is a Trilogy. Book 1 is complete and Book 2 starts serialization Jan 26th. Synopsis: ==================== He woke up in the wrong millennium. A 21st-century man is stranded in the heart of the Tang Dynasty, Zhang Rulin's first battle is for survival. It's a world of deadly conspiracies and martial masters who can kill with a single touch and he starts with no family, no identity, and no Qi at all. Using his foundation of modern knowledge and hobbies and entering into the service of a shadowy minister, Rulin must use his wits not just to survive, but to protect an innocent family and unravel a treasonous plot that reaches the throne itself, he must walk a path of shadows and steel, adopting the secret identity of the Black Wind Sword. Armed with forbidden knowledge and the mind of an engineer, he will craft new weapons, forge unorthodox alliances, and overcome the most powerful men in the empire. But as he delves deeper into this world of ancient power, the world pushes back. Can a modern man reshape an gilded empire, or will he become just another ghost in the city of smoke and fire?What to Expect==================== - Slow Burn: The story takes a bit to get going and for all the core characters to be introduced. However, in my humble opinion, its well worth the wait. - Historical Fantasy: The history of the world up until the protagonist arrives is identical to real world history. Some liberties were taken with the characterization of historical figures. Fair warning its not entirely historical, since Qi does exist, but is integrated such that it didn't change the flow of history. - Character Driven Story: The protagonist doesn't wait for the plot to happen; he makes it happen. - Multiple Progression Path: Tech, Ranks, Low Qi Cultivation, Martial Arts, and Empire Building. - Smart/Intelligent/Clever Protagonist: Our protagonist is a very well adjusted engineer who doesn't solve every problem with brute force or engineering. - Engineering/Crafting/Technology Gap: The introduction of more modern technology occurs across several fields. - Transmigration/Time Travel/Iseikai: Its historical transmigration, but there's also Qi empowered martial artists. - No System/No Cheats/No LitRPG: There are no RPG elements and the protagonist starts without unique powers outside of his knowledge and modern upbringing. - Secret Identity/Political Intrigue: There's action, but much of the story also revolves around politics and there are many disguises. - No Harem/Thoughtful Romance: There's no harem elements here. Your definition of romance may vary here too. A Strong Found Family Core. ++++++++++++++++++++++++++++++++++AI was used for technical editing, to help with research and translation, cover generation, and some filler text/writing advice (although I promise to commission an artist once I can afford it). I will also share the writing process in bonus chapters once I think the process is well polished.
