Forcing a king to obey?

Two weeks later…

An old woman and a young, blue-haired girl in purple dresses arrived at the gates of the royal capital of the Green Leaf kingdom.

"Grandma, can we really find aunt Hannah's family here?" The young girl asked.

The old lady looked at the giant city in front of her and shook her head. "I'm not sure, but we will surely find about their whereabouts. After that, we only need to go there and take back our family's heirloom."

The young girl nodded and then said annoyedly, "If grandma had recovered completely, we could force this kingdom's king to do our bidding, but now, sigh. We have to do everything ourselves."

"You little girl, you shouldn't always think like that. Although I'm strong, who can say for sure there isn't some old geezer hiding here?" The old woman said in a slightly reproachful tone.
