Siheyuan: Stay Away from Animals, I Will Get Rich by Signing In!

Li Jun traveled through the world of "Love in the Courtyard" and became a senior technician in a steel rolling mill. He was bound to the sign-in system at the beginning and received a large amount of materials. He watched the plots in the courtyard with a cold eye, refused to be taken advantage of, and slapped the beasts in the face. While signing in to build up strength, he waited for the opportunity to go south.
