Capítulo 64: Juggernaut's Heart.

The only good thing was that he was not the only one in the fight with a limit. Zain was also reaching his limit. He couldn't absorb anymore power. His body had reached its limit. Things were so bad that his body was aching with every movement. Even breathing had become laborrous. 

His muscles and bones were screaming out in pain every time he moved. It didn't help that he was bleeding all over.

None of the metal claws had managed to impale him, but all of the cuts on his body were leading to too much blood loss and the shallow cuts on his lungs were making it difficult for him to breathe. This was reducing his stamina and increasing the burden on his body. 

Eventually he became too tired to punch. He fell to his knees while breathing heavily. The sound of his inhalations and exhalations was like a drum being struck. It was so loud that it kept Kelvin from fainting. It kept pulling him back from total blackout.
