Ma Qing, a doctor of engineering mechanics, was accidentally electrocuted at a remote sensing archaeological site of Qin Shihuang's Mausoleum, and his soul traveled through the Qin Dynasty and became Ying Qing, the eighteenth son of the First Emperor. His biological mother died young and he has no relatives to support him. He is the most inconspicuous and "transparent" among the princes, and is nicknamed "The Fleeing Young Master" - he will only run away when trouble comes.
The crossing node coincides with the thirty-sixth year of the First Emperor's reign, when the Dongjun meteorite fell to the ground. Because of an unintentional remark at the palace banquet, he was framed by Hu Hai's party and was about to be sent to the bitter cold Longxi to guard the border - anyone with a discerning eye knew that this was a dead end.
Without the blessing of the system, without the magic weapon descending from the sky, Ma Qing only had a brain of modern physics, mathematics and engineering knowledge. At the critical moment of life and death, he had an idea and used his professional knowledge to talk nonsense in the court, claiming that "there is a dragon vein under Xianyang Palace, and he is willing to escape to the earth to find the dragon for his father, in order to live forever."
The first emperor, Ying Zheng, was anxious because his search for immortals was fruitless, so he unexpectedly agreed to this ridiculous request.
From then on, there was a "mad prince" digging holes all day long in the most remote corner of the Great Qin Palace. Everyone laughed at him for being a waste, but they didn't know that the end of the tunnel was digging through the lifeblood of the entire Great Qin...
This is an anti-conventional time-travel story: while other people in time-travel are arrogant and angry, my protagonist starts with only a shovel. In the court, he is a submissive "escape son", but secretly he is a rich infrastructure maniac. Let's see how the engineering man used a shovel to move the gears of destiny of the Qin Empire.
