After being shown by King just how much of a power gap there was between the two of them, Seven fired the area in fear that he might accidentally make King more mad than he already was and as such decided the best course of action was to leave before he got even more hurt than he already was.
"So that's what it was," said Julius, which made him realise why he was losing, to which Ling seemed to agree; however , it had also caused Julius to question something. That being how he failed to block the attacks of Seven but King could do it without seemingly to have any trouble with the task which caused Julius to question King as he wanted to know how hard it was and even if it was possible to attain the same level of strength so that if he had to actually battle someone with the same aspects as Seven in the future, he would be fully prepared for it and ready to absolutely wipe the flow with his opponents.
