Wang Zhan's mental energy remained spread to its maximum range.
While Huang Pufeng was talking to Du Ming, Wang Zhan sensed that something outside seemed to have changed.
Suddenly, the ground vibrated slightly.
The vibration was so faint it was almost imperceptible, but under the coverage of Wang Zhan's mental energy, this sudden change was exceptionally obvious.
"Shut up!" Wang Zhan said, frowning.
Huang Pufeng and the other two were startled by Wang Zhan's sharp whisper. However, Huangfu and Song Dongming knew Wang Zhan wouldn't speak without reason, so they both consciously fell silent.
A few seconds later, the tremors occurred again.
This time, the tremors were significantly stronger, so much so that Huang Pufeng and Song Dongming both felt them.
"Is it an earthquake?" Song Dongming asked instinctively.
"I don't know... This is bad!"
Wang Zhan's expression suddenly changed drastically. He hastily said, "Quick, take Du Ming and get out of here!"
