The purpose of writing "The First Assistant of Da Luo" is to bring engineering thinking into full swing with the situation of the Jiajing Dynasty. I stuffed the CAD drawings into the alchemy furnace, folded the sea ban into sails, and let Zhang Cong realize the formula of "harmony between man and nature" in the Longji Stone Chamber - without mountains, rivers and people's hearts, technology will end up being nothing more than an exquisite empty talk. I will try my best to tell every story!
