He is a modern eighth-level fitter and master of military weapons. He can calibrate to an accuracy of 0.002 Mm with a file.
When he woke up, he became Li Xiang, the eldest son of Tang Prince Li Chengqian - the eldest grandson of Li Shimin.
This year was the eighth year of Zhenguan. Tuyuhun invaded the border, the court was restrained, and the treasury was empty.
The twelve-year-old boy walked out of the East Palace and held out a crossbow machine in the Tai Chi Hall - five hundred steps pierced the Yang, three arrows were fired in succession, and the whole court was shocked.
Li Shimin helped him up with his own hands and said, "I have neglected you for twelve years. From now on, I will not neglect you again."
From then on, there was a young general on the frontier of Datang.
He led three thousand cavalry to attack thousands of miles, burned the enemy camp, captured and killed the enemy chieftain, and was awarded the title of Marquis in one battle.
He made sky-shaking crossbows, bowl-mouth blunderbuss, water-powered forging hammers, and standardized assembly lines, spreading the flames of the industrial revolution in the prosperous age of Zhenguan.
Wei King Li Tai regarded him as a thorn in his side, but he remained motionless; his father Li Chengqian was forced into a desperate situation, so he entered the palace overnight to save the day.
He saved his father, kept the East Palace, and was named the emperor's grandson.
He also wanted to save someone - Empress Changsun, who was about to die of illness in the tenth year of Zhenguan.
This is the death line he has set for himself.
Technological dimensionality reduction, military crushing, court games, and industrial revolution.
How did an engineer + the soul of Huo Qubing stir up the storm in the prosperous Tang Dynasty, growing from a neglected eldest grandson to a generation of heroes in charge of the world's wars?
"Grandpa, my grandson still has a lot of things in his mind that he hasn't come up with yet."
"Travel Lord of the Tang Dynasty" - This is not time travel, this is a dimensionality reduction attack.
