Modern construction foreman Zu Qing takes a desperate leap from the seventeenth floor to his death, trying to recover the unpaid wages owed to migrant workers. When he opens his eyes again, he has transmigrated into the spineless young heir of the Duke Who Guards the Nation's household in the Great Yan Dynasty. Despised by his biological father and bullied by his adoptive cousin, he's become a laughingstock in the capital.
Who could have guessed that this “useless wastrel” carried the soul of a modern man who understood infrastructure and knew how to invent things?
To deal with his awful relatives, he uses modern accounting to expose the household's embezzlers and seize back control of the family. In a poetry contest at court, he casually recites an adapted version of “Azure Jade Case,” astounding everyone and shattering his reputation as a fool. To ease the people's hardship, he makes cement, builds wheelbarrows, and repairs river embankments, protecting them from floods. When foreign enemies invade, he builds a defense line with cement fortresses and simple crossbow carts, forcing the Northern Di to bow in submission.
His brilliance turns heads at court and wins the hearts of four extraordinary women:
Su Qingwan, the exceptionally talented daughter of the Grand Tutor, draws infrastructure plans for him and willingly stays by his side;
Lin Miaoyin, the gifted daughter of the Imperial Medical Academy's chief physician, tends the wounded on the battlefield and develops soothing medicine for him;
Qin Yuwei, the formidable daughter of the General Who Guards the North, trains troops and protects the border for him, willing to use her martial prowess to keep him safe;
Even the empress, Zhao Lingxi, is moved by his talent for governing and his sincere heart, and is willing to set aside her imperial dignity to rule the realm with him.
From modern construction foreman to the ancient dynasty's Duke Who Guards the Nation, Zu Qing paves the road to prosperity with cement and brightens the Great Yan Empire with his inventions. In the end, he marries the empress as his queen and takes three beauties as consorts. The five of them govern the realm as one, transforming a dynasty beset by internal strife and foreign threats into a prosperous empire with infrastructure everywhere and happy, peaceful people.
It's okay, but the empress's name is Empress Zhao or Xiao. The father wanted to punish his own son too much, and when his enemies met, he became extremely jealous. Wasn't he already killed? How did it come back to life later? The writing is very confusing.
