Protagonist Xue Bufan: A social code farmer with little hair but a lot of dirty talk.
The creed of life is to never stand up if you can lie down, and never make a move if you can have sex.
As a result, he missed the mark and was directly assigned to Daqin by the system to engage in technological poverty alleviation.
Another protagonist, Ying Zheng (Brother Zheng): The biggest father of Party A in the world, the ultimate king of books, and late-stage obsessive-compulsive disorder.
In the early stage, Xue Bufan looked like a walking humanoid bug. Later, I discovered that this bug was really interesting and it was a super patch that allowed Daqin to directly upgrade to the new version.
