When Lin Yuan woke up, he found that he had become a poor scholar during the Qingli period of the Northern Song Dynasty. At the beginning, he only had a shabby house, a few acres of thin fields, and a hard-core golden finger of "God's Arm Crossbow Design".
Originally wanting to get rich by following the routines of Internet articles, he built a curved shaft plow to increase production and improved looms to help fellow villagers make money. Just when he thought life would calm down, a group of black-armored forbidden troops broke through the door. The leading general unfolded the imperial edict and read expressionlessly: "By God's blessing, the emperor has issued an edict: Xuan Linyuan enters the palace to meet the Holy Spirit."
In the Imperial Study Room, Song Renzong placed a list of annual tributes from the "Chanyuan Alliance" in front of him: "Lin Aiqing, I heard that you can make divine arm crossbows? Then... Can you make me a few cannons that can push to the sixteen states of Youyun?"
Only then did Lin Yuan realize that this emperor, who was known for his "benevolence", actually had a strong heart. When the thinking of science and engineering collides with the eternal emperor, the friction is not only gunpowder, but also thunder that changes the era.
When the report of the urgent battle at the border came, Lin Yuan looked at the drawings he had designed and asked the soul question: "Your Majesty, if this shot is fired, history will really be different."
How will this story unfold? Is it to enrich the country and strengthen the army and restore the glory of the Han and Tang Dynasties? Or is it the explosion of technology that started the Song Dynasty of steampunk? Or is this all a page destined to be erased from history?
