The mountain boundary remained quiet.
Too quiet.
From the sect's side, several observation formations had been activated along the outer ridges.
They were carefully hidden.
Invisible to ordinary perception.
But fully active.
Inside the observation hall, Instructor Han stood in front of a large formation array.
Multiple sensing plates were connected together, forming a wide detection network.
Lines of light moved slowly across the surface.
Xu Liang stood beside him.
"They stopped."
Han nodded.
"Yes."
"The fluctuations have stabilized at the boundary."
Yan Rui crossed his arms.
"So they noticed."
Senior Qiao, who stood nearby, spoke calmly.
"Most likely."
The room fell silent.
Both sides had realized something.
Neither had made a move yet.
Lin Xuan stood quietly at the side.
He had already sensed it during cultivation earlier.
The presence that had been approaching—
Had stopped.
Just outside the sect's range.
"They're observing," Lin Xuan said.
Instructor Han glanced at him.
"That matches our readings."
Xu Liang frowned slightly.
"That means they're not ordinary cultivators."
Yan Rui smirked faintly.
"Of course they're not."
"Anyone who can track something like this wouldn't be simple."
Senior Qiao spoke again.
"No one leaves the sect without permission."
His tone was firm.
"We do not expose ourselves unnecessarily."
Lin Xuan understood the reasoning.
If they moved carelessly, the other side might confirm that the source of the fluctuation was within this territory.
For now—
Silence was their best option.
That night, Lin Xuan returned to his courtyard.
The air felt heavier than before.
Not because of the spiritual energy—
But because of the situation.
He sat down and began cultivating.
The moment his spiritual energy circulated—
The network appeared again.
Steady.
Massive.
But now—
There was a clear disturbance at its outer edge.
Not chaotic.
Not aggressive.
Just… present.
Lin Xuan focused on it carefully.
The sensation was different from the node reactions.
More controlled.
More precise.
"They're using detection methods," he murmured.
Far beyond the boundary—
The scouting team remained stationed along the mountain ridge.
They had set up a small observation formation.
A faint barrier concealed their presence.
The formation instrument hovered above a stone platform, emitting soft lines of light.
One of the cultivators spoke quietly.
"The fluctuations are consistent."
Another nodded.
"The source is definitely within that mountain range."
The leader stood at the edge of the ridge, looking toward the distant peaks.
His expression remained calm.
"Any signs of direct movement?"
"No."
"Nothing."
The leader narrowed his eyes slightly.
"They're being cautious."
One of the cultivators asked,
"Do we proceed?"
The leader shook his head.
"Not yet."
He turned his gaze back to the formation instrument.
"If they've already set up observation formations…"
His voice lowered slightly.
"…then they're aware of the system."
The group fell silent.
That changed everything.
Back in the sect—
Inside the observation hall—
Instructor Han studied the shifting lines once more.
Then spoke quietly.
"They're not leaving."
Xu Liang frowned.
"So it becomes a standoff."
Yan Rui shrugged.
"For now."
Senior Qiao remained calm.
"Then we continue observing."
Because at this moment—
Neither side knew the full extent of the other's knowledge.
And the first to make a wrong move—
Would reveal everything.
