The main reason was that the knocking sound was too hurried. It was obvious that the person at the door was very anxious. This also puzzled Qin Yue and Song Xiaomei.

Puzzled, the two cute girls walked to the door of the courtyard. When they looked outside, they immediately revealed puzzled expressions.

That was because the person at the door was their friend, Hei Niu, who had an eagle as her Summoned Beast. It was really strange for Hei Niu to appear so anxiously.

The courtyard door was opened by Song Xiaomei, who asked in puzzlement.

"Sister Hei Niu, why are you here? Why are you in such a hurry? Did something happen?"

"Something big happened, and it has something to do with you guys. It's very serious," Hei Niu said anxiously, her expression very grave.

"Something to do with us? What's the big issue?" Song Xiaomei said hurriedly.
