As it turned out, Du Youqian's suspicions were a bit unnecessary.
Nothing happened all the way until he walked out of the tunnel.
Looking back, his earlier cautiousness seemed somewhat laughable.
Of course, if he had to do it all over again, he would still choose to be on maximum alert.
Outside the tunnel was an extremely vast underground space, about the size of fifty soccer fields.
It was roughly a mile or so long and wide, but its shape was irregular, likely built according to the mountain's natural contours.
A number of thick stone pillars stood on the ground in a specific pattern, making it look like a plaza or a grand hall of ancient design.
But Du Youqian, with his discerning eyes, could tell that the stone pillars were actually meant to work in conjunction with an Array.
Du Youqian cautiously extended his Divine Sense to probe the area.
