Traveling Through the 70S, I Have a Secret That I Can't Tell

Two male protagonists + sweet but not abusive + system + protagonist's suffering Ying Nian was originally a good young man in the 21st century. After working hard for seven or eight years, he finally bought a 50-square-meter "big house" in a small city on the 18th tier. Today was a good day to accept the new house after the decoration was completed. Unexpectedly, he fell down as soon as he stepped over the threshold. When he opened his eyes, he saw this scene in front of him. Going to the countryside? No---, ok, my elbow can't twist my thigh Don't want to prepare luggage? No---Okay, I have arms and legs so I won't starve to death. No... Ying Nian's vision went dark, and his heart was still racing the second before he fainted. What the hell? I... I have to keep a secret and I can't tell it. Fortunately, God has been kind to me. I actually had a good career and love in 1970.
