The tremor came suddenly, catching everyone off guard.
Yan Tingfeng abruptly turned around, only to see a massive gate had appeared before them.
The five of them were thoroughly separated.
"There was no earthquake warning today!" Professor Foo exclaimed in shock, "We have to get out of here fast, or if Yan Mountain gets sealed off, we're done for!"
In the last three hundred years, Yan Mountain had been sealed off numerous times.
With each occurrence, many people had lost their lives within it, and eventually, not even a single body could be found.
Perhaps they had become one with the depths of the ground, merged with Yan Mountain itself.
"We can't leave," Xiang Lefeng said sharply. "They're trapped inside; we have to open the stone gate!"
However, before he could act, his collar was yanked backward by a hand.
"Bang!"
Just as Xiang Lefeng stumbled backward the very next second, another giant rock fell, crashing in front of him.
A drop of cold sweat beaded on his forehead.
