When the gas tank exploded, Li Dejiang, an engineering student at Zhejiang University, was directly transformed into the second son of the Li Jing family during the Zhenguan period - a naive boy who "talked nonsense" after falling off a horse. He searched all over his body for his cell phone, pulled Li Jing's beard to ask for the WiFi password, and said "Happy Father's Day" to his father. As soon as he arrived in the Tang Dynasty, his life turned into a huge oolong scene.
But who would have thought that this stupid boy has a "cheating" skill hidden in his hands: he can accurately calculate the range of the trebuchet, but he forgets to calculate the wind direction and destroys his own grain and grass; the improved keel waterwheel saved the drought, but the drawings did not indicate the dimensions. Squatting on the field bank and "gesturing" with carpenters to make changes; in order to find potatoes with "ten times the yield per mu", he ran all over Chang'an carrying a round picture of a pimple. He also mistook radishes and sweet potatoes as targets, and cried while holding radishes until the caravan set off for the third time.
Entering the court, it was even more difficult: preparing gunpowder to blow up half the courtyard wall and hitting Qin Shubao's dog, but Taizong rewarded him with brimstone and saltpeter so that he could "continue playing"; building a fire door and a gun that shattered the emperor's teacup, thinking "I must use better iron"; building a public toilet and squatting next to it to record the "feces fermentation account", scaring the officials to take a detour, but they really prevented the plague.
Later, he joined the army in the Western Regions and brought half a bag of potato seeds as dry food. He chased the enemy into the desert and relied on the stars to identify the direction. After winning the battle, he grabbed the king and asked "Is there any crop with a higher yield than potatoes?"
While others were fighting for power, he thought about installing steam engines on plows and equipping the Tang army with flintlock muskets.
