Yeah but Cao Cao and Ophis case is a thing.
Cao Cao used the single strongest weapon in the whole series, he hit her with it and it produced a light so strong that even though they put a barier around the light, Ise stated that it could heavily dmg even higher class devils. Ophis on the other hand actually took the hit not the light. After it all ended, ophis didn't even budge.
……I understood that the light created from the holy-spear was intense even from inside the mist! If we didn't have this mist, I wonder how much damage would we, devils, have received just from the torrents? The light of the holy-spear stops, the mist of darkness also disappears, and I looked at Cao Cao and Ophis. Ophis still had a spear pierced through her stomach. But there was no blood flowing out from her stomach and she also didn't have any expression of pain on her face! Cao Cao takes out his spear slowly, Ophis's stomach had a hole but there were no traces of blood. The hole disappears as if nothing happened.
…..So she didn't take any damage? Even with the light of that holy-spear…..? Cao Cao then says it with an astonished face.
"An instant kill attack if it was a devil. I even put a lot of power in it so even other beings would vaporise…… It would have taken half of the power of one of the Gods who are weak against this spear."
Cao Cao then looks at me.
"Did you see that Sekiryuutei? This is Ophis. You cannot give it a critical wound even with the Ultimate Longinus. The damage went through. ---- But it is impossible even for this spear, to take down the power of the infinite."
Since Ophis herself is infinite, does it mean that no matter what kind of attack you do with that spear is useless…..?! So this is a dragon that represents Infinity. Cao Cao continues while tapping his spear on his shoulder.
"She won't even fight back against me who just attacked her. The reason is simple. ---That's because she can kill me any time she wants to. That's why she won't do it, even if I do something like this. Basically she's not interested in anything besides Great-Red. Out of the Top 5 world's strongest not including Great-Red, the strongest one is Ophis, and there is a huge gap between her and the second strongest where you could say that she is on a totally different level. This is what the embodiment of Infinity means."
These guys….. Cao Cao is after Ophis right? Then I thought about it. ……Then what are they planning to do with this "Infinite"? Even if it is Cao Cao, it would be impossible to defeat her right? Or can he beat her if he uses Balance-Breaker or the thing called Truth-Idea…….? No, judging from how Cao Cao spoke, he's basically saying that he can't beat her.
So yeah there's that. I don't think there is any question about Ophis at this point. She IS abstract.
