My Parents Are Both Working, so the System Asked Me to Sit on the Bed

[Seventies + Space + System + Entrepreneurship + Craftsmanship + Good Luck] When I was reincarnated, I thought I would come to a whole new world, but I never expected that I would be in the 1970s. But I am very lucky to be born in a dual-income family. In this era, a dual-income family is equivalent to a well-off life. Although he is not rich, he is still very satisfied with this kind of life. But I never expected that when I was 5 years old, a deceptive system would appear and even let me, a child, go to the Kang bed. But after finishing the first game in my life and seeing the rewards, I realized how great this system is.
