Li Mo, the youngest academician of the Academy of Engineering in the 21st century, traveled to the Liang Dynasty in an experimental accident.
At that time, the dynasty had already suffered from serious problems: the barbarian cavalry in the north were knocking on the gate every year, the feudal towns in the south were separatist and did not obey orders, the powerful officials in the court were in power and the parties were fighting endlessly, and the common people were even more hungry and poorly clothed. And the identity he traveled through time was just the son of a criminal official in Lingnan who was demoted to guard the border and could not even have enough to eat.
But Li Mo soon discovered that the technological level of this world was roughly equivalent to the transitional period between the Tang and Song Dynasties. In other words, the physics, chemistry, and engineering knowledge he has in his mind can be used as a dimensionality reduction attack here.
He began to use the simplest tools to change his destiny step by step.
At first, it was just to survive: he improved the curved shaft plow to triple the output of an acre of land; he invented the water-powered forging hammer to increase the output of ironware. Gradually, the things he made became bigger and bigger: he used coke to make steel to create swords and armor that were far ahead of this era, used a spinning machine driven by a waterwheel to weave cloth that was cheaper than Shu brocade, and used a double-piston steam engine to move the gears of the entire industrial revolution.
The local people called him "the son of heaven". The court regarded him as a serious problem. The barbarian tribe offered a reward of ten thousand dollars for his head.
But Li Mo knew that technology alone could not change this old cannibalistic order. When the emperor summoned him to the capital three times and was given a death edict, he laughed.
Since this emperor doesn't give him a way to survive, then he will create an emperor himself - be the emperor himself.
