Beast Control: Summon an SSS-Level Girl at the Beginning

This is a world that belongs to the beast master! Some people summoned an extremely powerful five-clawed golden dragon that soared around the world and looked down upon everything in the world, while others summoned a black turtle to guard the border, suppress evil spirits, and protect the border... I, Lu Xuan, am a declining genius. On the day of my awakening, I accidentally summoned a small skeleton. Who would have thought that the little skeleton was actually the God of Death! Death is a girl! Others control beasts, I control gods!
