As the Queen of Inner Earth, Flame had a thorough understanding of Earth's center. While her status as The Second-Level God Slander made resisting Sophronyx a challenging task, she faced no difficulty in launching an attack to the weakest part of the Earth's center. Sophronyx would certainly never risk allowing Flame to strike any part of the Earth's core with her Life Red Lotus. This was why he had tried his best to restrain his power during the conflict, so as not to inadvertently unleash it. The Earth's core was a sensitive area, the slightest change here could spell a massive disaster in the outside world due to the butterfly effect. If the Earth's center were to collapse and the Earth's Core Magma destroyed the planet's interior, the entire planet could be in serious danger.
Ji Dong relayed two pieces of information to Flame through their soul connection; the first was to use the survival of the planet as a threat, the second was to shift the battlefield to the Core Lake.
