Liu Qian's magic show is popular all over the country, and Xiao Ming also started to learn magic. He invented a magic box. When any pair of real numbers $(a, b)$ enters it, a new real number is obtained: $a^{2} + b - 1$. For example, if $(3, -2)$ is placed in it, then $3^{2} + (-2) - 1 = 6$ is obtained.
