A scout from the Investigation Battalion led the way.
"Alliance Leader, the main abnormal force headed this way."
The scout pointed at the dunes ahead and called out.
"Our men have been trailing them, but they haven't dared get too close."
Su Ming nodded slightly and looked into the distance.
Yellow sand filled the sky, stretching beyond sight.
He could faintly sense a trace of abnormal aura ahead.
There were quite a few of them, moving slowly.
"Slow down."
Su Ming gave the order.
"Don't let them discover us."
"As you command."
Everyone immediately concealed their auras and slowed their steps.
Like fish swimming through a sea of sand, the group advanced without a sound.
They walked for roughly four hours.
A vast depression appeared between the dunes ahead.
A cluster of ruined buildings stood at its center.
Judging by its size, it looked like an abandoned ancient city.
But most of it lay buried beneath the yellow sand.
Only the outlines of its highest points remained visible.
The main abnormal force had stopped outside the depression.
Densely packed soldiers were clearing the dunes and digging out an entrance.
"What is that place?"
Su Ming asked quietly.
The scout beside him thought for a moment before answering.
"Alliance Leader, those should be the ancient ruins of Yellow Sand City."
"They say it was destroyed during the ancient war, too."
"It's been buried under the sand for tens of thousands of years. No one has ever paid it any attention."
"Why are the abnormals digging it up?"
The scout looked utterly puzzled.
It was just an abandoned ancient city.
Did that really warrant mobilizing so many troops?
Su Ming's gaze sharpened slightly.
He could sense it.
Deep within those ruins, there was a faint spatial fluctuation.
It somewhat resembled the fluctuations
