Valerian did not intend to go easy on a creature that was after his life. So when the beast was flung into the void, the young man moved and used the momentum from the previous blow in the ribcage. Then he delivered another punch to the body of the beast. His punches were hard and significantly impacted the beast, making it groan.
The beast was left without any air to breathe. He did not understand how this human could produce this much strength from his fists. Magical beasts were not only blessed with magical capabilities but also physical strength too. Valerian, however, did not intend to leave things halfway. He kept delivering punches from left and right to the beast's body.
Valerian was delivering all the momentum behind the punches to the body, and he had already broken up the ribs of the tiger beast. The bones had been fragmented and pierced through the beast's lungs, turning them into a sieve.
