Liu Ming's face was slightly pale, although he possessed one hundred and fifty-three mana crystals that granted him profound mana, maintaining such a large formation on his own was extremely strenuous.
"Your cultivation is not enough; even with the Guiding Formation, it seems you still can't trigger the Jiutian Divine Thunder," Luo Hou's voice emerged in Liu Ming's mind.
"Senior Luo Hou, what should we do now? I fear my mana won't support the formation much longer," Liu Ming asked urgently.
"Now we can only take a risky move. Boy, use your Yuan Spirit Flying Sword to draw down the divine thunder," Luo Hou slowly said.
On hearing this, Liu Ming was greatly shocked. The Jiutian Divine Thunder was at stake, and although his Yuan Spirit Flying Sword was only a nascent magical treasure, directly striking it might damage it.
