Introduction to the novel "Across the Tang Dynasty: Turning Things Around"
Lin Yu, a student of the Department of Mechanical Engineering in the 21st century, woke up and became the unlucky scholar who was about to be executed during the Zhenguan period! On the execution ground, he relied on his memory to recite "Zhenguan Politicians" to express his innocence. After escaping from death, he was shocked to find that he actually had a "modern technology library" hidden in his mind - capable of restoring soap, glass, gunpowder and other processes.

He even took the risk to experiment with sulfur and gunpowder, burying "shaking thunder" in clay pots into the enemy camp. When it exploded, the fire lit up half of the grassland, and the flag of the Turkic Khan shattered into powder.
