Wearing red clothes, but with different stances; the two died for their country and love, and the story should have ended there.
Xiao Shuhe (present life: Xie Yanhe) - strategic, calm and restrained; in ancient times, he was the sixth prince/regent, and in the future he will be an external curatorial consultant for the "Institute of Time Ethics".
Duan Zi'ang (current life: Duan Ziyou) - executive type, decisive and sharp; he was an assassin leader in ancient times, and has a combined background in cultural relic restoration and material engineering in the future.
But he woke up in the Node City thousands of years away - where the bifurcation of history can be observed, but crude rewriting is prohibited. Xie Yanhe and Duan Ziyou got a chance: to return to a parallel Zimo Dynasty with a "low intervention package" (basic medical care, paper, ink and water conservancy, non-lethal armor, and copper bell signal network).
They no longer compete for supremacy, but mend the cracks in the world: building civilian communications with bells and flags, stabilizing people's hearts with canals and warehouses, and reducing unnecessary casualties with armor formations that "protect without killing." The faster the reform, the tighter the "causal threshold" - history will use other methods to recover the "entropy debt". Between disasters, famine, the old aristocracy's counterattack, and ethical trials, they learn restraint and choice: save you, but not destroy the world; love each other, but also let more people live.
The peach blossoms will still fall, but this time, they use them as fire - to light up the way home.
Intention: The great responsibilities of family and country, sincere feelings will always be found, again and again
