Although Wu Mei's question was intricate, Zhan Yun absolutely would not drop the ball; deceiving people was, after all, a strength of the lineage of the Valley of Ghosts.
At this moment, Zhan Yun gave a mysterious smile, "Do you think any place is suitable for setting up an Earth Formation?"
"An Earth Formation is also limited by the terrain?" Wu Mei asked in surprise.
Zhan Yun chuckled, "Of course! An Earth Formation not only requires special terrain but also can only function for a period of time and needs a very long cooldown period."
"What do you mean?" Wu Mei asked.
Zhan Yun heaved a long sigh, "The power of the earth is vast, but it isn't something that can be employed on a whim. Take Zhuge Liang's Eight Trigrams Array as an example, once activated, it cannot be maintained for more than three days. After three days, the Formation automatically becomes ineffective."
