Deep in the Grand View Garden, a bronze steam engine is quietly running under the Xiaoxiang Pavilion, and its pulse resonates with the lines of the psychic jade on Daiyu's wrist. When Daiyu came into contact with the principle of steam for the first time, she discovered that these machines can amplify her perception of the emotions of vegetation; the elders of the Jia family regarded steam as a heresy, and Baoyu was obsessed with its power. The relationship between the two went from tacit understanding to rift; Daiyu accidentally activated the "steam talisman array" recorded in the ancient scrolls, causing some buildings in the Grand View Garden to levitate, causing shock to the government and the public; Wang Shuirong of Beijing intervened as a steam consultant, but in fact he coveted the core of the talisman array; Daiyu displayed steam lanterns during the Yuanchun Provincial Festival, but was accused by the queen of Magic, the Jia family is in a crisis of inspection; Daiyu, Zijuan and Baochai secretly repair the damaged steam core, and find that it is connected to the fate of the Twelve Hairpins of Jinling; Baoyu is imprisoned by Jia Zheng for protecting the steam furnace, and Daiyu has to team up with Tanchun to break into the archives of the Ministry of Industry; The key to the steam era - a set of tools that can rewrite The "sequencer" of the gear of destiny - hidden in the roots of the purple grass in Daiyu's previous life; Daiyu enters the illusion of Taiyu through the resonance of steam, and sees the prophetic book of the changes of the vigilant fairy; she must make a choice between Baoyu, her family and the changes in the world, and the ultimate secret of steam points to the destruction and rebirth of the Grand View Garden
