[Transmigration, alternate history, decisive and ruthless.]
Lu Huaian was transmigrated years ago and ennobled as the Marquis of Ding'an.
On his wedding night, the emperor schemes to kill him out of suspicion, while the Grand Princess chooses to go along with it in pursuit of power.
By a twist of fate, he survives the disaster. When he wakes, he is already at the frontier, and from that moment on, he ventures ever further down the path of technological development.
His wife, who once felt nothing for him, also begins to think of him constantly.
