Inside the vortex of fog, fog surged like a tide and surged rapidly like a fierce spark stirring up a raging flame.
Nonetheless, at the edge of the vortex, they were blocked by an invisible barrier. This was a unique phenomenon that had never happened before. This barrier was the Defensive Formation that Ou Yangming had set up, and it could block the fog in the vortex outside.
Inside the formation, Ou Yangming and his companions stood side by side.
Ou Yangming's eyes were filled with an inexplicable meaning. He looked at He Jian and asked in a calm voice, "Senior He, how much spiritual Qi do you have left in your dantian?"
"70%." He Jian slightly shook his knees, and the sword case on his back also began to shake.
"70%..." Ou Yangming looked like he was deep in thought. His fingers gently stroked his chin as if he was thinking about something.
