Pokémon: the Strongest Winner in Life

Traveling to the world of Pokémon, I have an older sister, Sirona, who is a younger brother. She originally wanted to rely on her own abilities to become the strongest trainer, but... "Congratulations to the master for opening the newbie gift package and winning the divine beast lottery once!" "Congratulations to the master for drawing the super mythical beast Flash Rayquaza!" Wuyou looked at the Poke Ball in his hand and was speechless. Obviously my dream is to become the strongest trainer by my own ability. What does the system mean? "Why has my dream been realized before it even started?" Wuyou's face was troubled, but his heart was filled with joy. This novel and its characters are purely fictitious.
