I'm fighting back in the ninja world with spells

Thank you, people are in the ninja world, just got out of the hospital bed!
Surrounded by a group of people in black robes with frantic eyes, there is also a big gray back named Feiduan who is laughing wildly at him.
Just because he was the second 'lucky one' who successfully 'survived' and obtained the [immortal body] in this divine selection ceremony.
Shinji Akagi is a little numb...
What made him even more depressed was that after the transformation, his body had no chakra, but he could no longer practice any ninjutsu.
This means that he will become the first undead to endure!
But the activation of a strange system brought a whole new change to his life.
Can't learn ninjutsu?
small issue!
Here are all kinds of magical spells for you to choose from!
Crimson blood exercises, spirit spells, ten kinds of shadow spells... everything.
Wait a minute!
Why is there [Cursed Wind Cave]? !
Is this also a spell? ! ! !
Forget it, whatever, the field expands, and there are boundless spaces!
