On a particularly exciting and terrifying night, Zhang Jin, who was about to kill ghosts, suddenly traveled to ancient times, which frightened him so much! Although he is usually just a fool who fools around, you can't treat him so inhumanely! Fortunately, he met a pretty good-looking young man there who was willing to take him in. This strange young man didn't know how to cook or wash clothes. He could only turn into a gust of wind and get into Zhang Jin's sleeves (?!). So the two of them started a happy life of growing grass (?) And occasionally fighting monsters!
