Modern Science and Technology Came to Fruition in the Tang Dynasty

When I opened my eyes, I became Pei Yuan, a poor man from the Zhenguan period. >The family is surrounded by walls, creditors have blocked the door, and even the rice jar has reached its bottom. >I silently took out the chemical formula: soap, perfume, sugar... Make a lot of money from it first. >The improved waterwheel is worshiped by old farmers as gods, and the refined steel formula makes the general supervisor jealous. >Until one day, Li Shimin narrowed his eyes while looking at Quyuanli's report on increasing production: >"Is this Pei Yuan a blessing from God?" >He waved his hand: "Xuan Peiyuan enters the palace and gets me something bigger!" >I spent the night sketching out the steam engine - this time it seemed like I was going a little too far.
