I see!! I asked because of what Azazel said.

''Although it was only temporary, his body did indeed handle the power of infinity. If it was an ordinary Devil or Dragon, their body wouldn’t be able to withstand it and they’d die within a few seconds".

So this made me wonder how did vali was able to whistand that power, so was it a blessing like she did with Diodora and Shalba or real power of infinity that Issei used. Because it was stated that issei awakened ophis power( the one she gave him when his body was rebuild), so the power that Vali used isn't as powerful as the one Issei used?? Forgive me Hahah i just have soo many questions, and hope that Vali's powerup isn't an asspull just to reach Issei's level or surpass him again.
