There are those who help children with myocardial infarction, those who jump off a building, and... time-travel! Some take parent-child photos, some wear parent-child clothes, and some... Parent-child time travel! I am the one who travels through time. Time travel is not what I want, but my sonIt is a thought in my heart. A reluctance time travel, mother and child meet in another time and space, the two depend on each other, from strangers to acquaintances, from exiles to craftsmen, from business careers to official careers, making fun in bloodshed, and having fun in scheming. OpenA journey with only mutual love and no generation gap!
