A top mechanic accidentally passed through his soul and became the son of a humble carpenter from the Dayin Dynasty. At this time, we are in troubled times, with wars and smoke rising everywhere, and people's lives are like grass. Now that it's here, let's make peace with it! He used Luban ruler as his pen and fine steel as his ink, integrating modern mechanics into traditional mortise and tenon joints. Divine arm crossbows, repeating fire guns, and even steel armor... When the humble workshop resounded with industrial roar, he vowed to build an iron-blooded road to heaven in this era of cold weapons!
