Yueji: Whose Summoning Spell Is so Useful?

The author has been searching for monthly novels on Tomato for a long time, but he couldn't find the unlimited streaming novel he wanted to read, so he planned to write one by himself (no system, single heroine, unlimited streaming) (if you don't like it, don't criticize it) (if there is anything wrong in the writing, you can point it out, and the author will try his best to correct it)
