At the Beginning of the Game, I Became the Steward of the Goddess

After traveling through time and becoming the housekeeper of a down-and-out family, his identity is still a demon that everyone shouts about. Moreover, there are only two people in the family, the eldest lady and him. Han Shen expressed his helplessness. Fortunately, the check-in training system is enabled. As long as you check-in or teach the eldest lady every day, you can get generous rewards... "Punch in on the first day, get full cooking skills, low-level amulet, and 100 gold coins!" "Punch in for seven days and get the Demon Suppressing Tower, the great Heavenly Demon Art, and 1,000 gold coins!" "Punch in for fifteen days and get the essence and blood of the Blood Demon Ancestor, the Shadow Corps!" "Punch in..." Han Shen, who has various terrifying titles, always responds with a smile every time Miss Lin asks about him. "The rumors in the world are not to be believed. I am just the young lady's housekeeper, nothing else." Behind the scenes, the introduction is weak, please read the text.
