Axel saw that black necklace around his neck and he felt that Kevin was not powerful enough to remove it, Kevin must have felt their connection because he said to him via their telepathic link, 'This fucking necklace is protected by shields that's why I can't get rid of it, the Chains of Restraint have already destroyed 2 of them but I'm out of strength honey.'
Axel could feel his pain through their mark and his refusal to stay with that necklace any longer, so still following his instincts he focused on their mark again and sent all the energy he could to him through it.
Their friends who were looking at them with concern saw Axel's red aura expand and envelop Kevin completely, and then they saw this aura concentrate completely around Kevin's neck.
hello everyone,
don't worry the bonus chapter is coming :)
