In fact, Xiong Ba could invoke Hongmeng's incarnation of Divine Power from the Divine Spirit Mark with just a single thought. Even in situations of extreme danger, where annihilation was imminent before they could react, Hongmeng's Divine Power incarnation within the Divine Spirit Mark would autonomously revive and protect their lives.
As for Bibi Dong, even though she had already used the Divine Power within the Divine Spirit Mark once, in reality, Hongmeng's brand was still there. It could shelter her just the same.
They were simply unaware, believing that once the power within the Divine Spirit Mark had been used, it couldn't be utilized again until after a recovery period. In fact, this was a misconception imparted to them by Hongmeng. It was to prevent them from relying too heavily on his strength.
