During the previous night:
"Do you dare threaten us? Know your place!" Layla's voice commanded everyone's attention. Every elder in the valley followed the blasts of the battle, leaving the place empty of Supremacy Phase cultivators behind them.
However, there was an exception. Many figures dressed in black assembled around the sixteenth-highest mountain. As if they knew it would happen, they all channeled their Qi simultaneously a few seconds before the first blast of Layla's attack, isolating the mountain from the rest of the valley.
The black-hooded cultivators split into two teams. The first team created a human formation as they circled the mountain, covering it with a dome made of Darkness Qi, Wind Qi, Sound Qi, and Light Qi. It was practically one huge combined technique generated by all those cultivators.
Due to the barrier, the sect members residing on that mountain remained unaware of Layla's attack.
