"¡BOOOM!"
The sound that originated was not different from the one of a missile landing on a building before shattering it to pieces.
Aaron clenched his teeth as that punch violently pushed his body back. Luckily, his feet were still in contact with the ground, so he was able to use the friction to diminish the momentum and regain control of his body in a matter of seconds.
Everybody saw how Aaron's body stopped twenty meters away from Cain, with a clear fist imprint in its abdomen. What left everybody shocked was the blood leaking from the corner of his mouth.
Even Aaron was surprised to see that. His body was incredibly resilient, and the technique he trained not only transmuted his skin but all the flesh and viscera, granting him overwhelming defensive power.
The fact that Cain was able to generate internal damage in someone so powerful as Aaron left all the soldiers in a state of shock.
