"After time travel, I was scolded as a cheap slave by my daughter. Later, she blocked an arrow for me, and I rubbed an empire of stars with my hands for her."
Modern deliveryman Lin Zhigang, with a mortgage and memories of oil pollution, has transformed into the lowest "barbarian craftsman slave" in ancient times.
When they met for the first time, Jiang Xiaoyu, the daughter of the Shangshu Mansion, pinched her nose and sneered coldly: "A vulgar person with dirty hands is worthy of stepping into the door of my Jiang family?"
He looked down at his hands repairing the car and smiled.
Later——
He used a lever to repair the carriage that all the craftsmen in the city were helpless about, and the house was shaken.
He used a few knots to save the life of the current minister, and was promoted to a retainer.
He made a self-ringing bell and presented a universal instrument. The stars he rubbed with his hands rotated forever in the palace.
The daughter who used to ridicule him, but when he was falsely accused and imprisoned, she risked the lives and reputation of her entire family and knelt in front of the palace gate to cry out for him.
When he was coughing up blood and supervising the work, and his life was hanging by a thread, he used his body to block the poisonous arrow from him.
He held her dying, his eyes were red, and his voice was heartbreaking:
"Jiang Xiaoyu! Water transportation, national foundation, and Qianqiu achievements—all of them combined are not even one ten thousandth as important as you!"
From "You don't deserve it" to "I only want you",
From a humble craftsman slave with greasy hands to the "Lin Gong" who is in charge of national weapons and is famous all over the world.
In his journey, he did not rely on the system or golden fingers.
It is about mathematics, physics and chemistry engraved in the bones, and an ingenuity that wants this era to see science, women, and mortals change their lives.
"This is a delivery boy using physics to change the world, and at the same time, he asked the proud daughter to subvert Tsunada for him.
