Bab 1630: "Asmodeus Self-sacrifice Plan" 

Anyway, the virus didn't have Asmodeus' evil aura, which means the chance of getting discovered would be extremely low. 

As for whether the virus would affect Gabriel and make him listen to Ainsley, that's another matter. 

[If we fail to influence the archangel, we will forcefully push Gabriel to the gate with all of our might.] the team leader added. 

He didn't say that to achieve this, he and the other demons, plus the evil spirits, planned to use all their capabilities, even if they had to sacrifice their lives in the end. 

The evil spirits could be revived, but the demons couldn't. 

Still, the merit of 'killing' an archangel by letting the archangel 'give up' on the fight would give the demons involved in the plan a huge merit. 

Maybe, relying on this merit, they could be revived even if they died.
