Gu Nian thought about her younger brothers and felt that they were giving her a headache. She agreed with Gu Ren's idea of setting up a nursery to discipline her younger brothers.

She began to recall the process of the birth of a life.

Well, if she wanted to use contraception, she could start from here. There were 30 days in a month. Excluding the few days of discomfort, there were only one or two days with a higher chance of winning the lottery. She would rule out these two days and pay more attention to the days next to them.

When she first transmigrated, her period was not regular at all, but ever since she met grandma Xiao, the miracle doctor, she had adjusted it very regularly for her.

Since her period was regular, it would be very easy for her to find her for two or three days when her chances of winning were high.
