Breakthrough

'Will my body hold on ?' He thought to himself . His mind racing with possible solution. 

With 40 AP left, he allocated them to his endurance, recognizing its importance in increasing his overall tolerance. 

Endurance (A-) > (A+) =40

The pressure from his body had subsided a little, but he felt like he needed to build a much stronger body to achieve better effects. 

He could still see a lot of black-red aura pouring out of his skin, and he could tell that it was not good news for him at all. 

'I needed to confined everything to build up the energy pressure more. ' He thought to himself. 

If this breakthrough depended on his capacity, and his body was the vessel, then creating a super hard body was the key . 

Enhance Bones (I)> (XX)

Bone Control (I) > (XX) 

After increasing the skill of these two abilities, he exerted control over the bones inside his body, to form exoskeleton around him. .
