Is It Reasonable for the Necromancer to Summon an Angel at the Beginning?

Lin Ce followed the summoning notes left by his great-great-grandfather, and after all the hard work, he finally gathered the materials needed for the summoning. The legendary ferocious three-headed dog? Skeleton soldiers who are good at beating? Or the God of Death who specializes in collecting souls? Or maybe she is a succubus lady who specializes in charming people's hearts? Just when Lin Ce was a little excited about what a necromancer could summon, Lin Ce was interrupted by a sentence: "excuse me, are you my master?" At this time, he saw a girl with two pairs of wings in front of him, slowly falling from the sky to the ground, and as the girl's bare feet landed on the ground, a pure holy light hit her body. Then the girl slowly opened her eyes and saw Lin Ce, who was a necromancer, and said "*! It's a necromancer! Take your life!" What to do? I accidentally summoned an angel at the beginning. She wants to hack me to death. I'm waiting online! ! Save the little skeleton's life! This novel and its characters are purely fictitious.
