Marvel's Summoning the Nightmare Knight

Wait, stay away from me, who are you? All the same person? Don't be kidding, it's obviously so different... And you said I was your contractor? But I'm just a nameless little good student, not a cheating protagonist at all? What? Believe in yourself... I can't help it, I think I'm doing fine now... Qin Yunxiao, who was hanging upside down on the tree: Wait, I didn't say anything just now. I accepted this contract and just asked a few people to save me! ! ! This is a story about an ordinary student who accidentally saves the world with seven nightmare bats. It is also a story about trying to protect and regain the emotions while putting aside the funny shell. PS Nightmare Bat is Batman who has obtained the seven dark dimensions corresponding to the power of the Justice League.
