"The Romance of All Weapons":
At the peak of the Spring and Autumn Period of the Qin Dynasty, hundreds of schools of thought including Mohism, military strategists, and kendo contended. Later, the sword god Lin Qingyi defeated 12,000 enemies with one sword, and kendo took the lead. The Mohist family retreated, and the military strategists were broken up into many weapon sects and lost their former glory.
From then on, the Qin people's reputation for favoring swords spread far and wide.
The words "All the heroes in the world come from my sword sect" made all the young people in the empire practice with swords, hoping to one day succeed and become famous in the Qin Dynasty.
The story of this book slowly unfolds from the young man learning swordsmanship in Jiangnan Town, and depicts for you a great empire that has nothing to do with the historical Qin Dynasty.
