After returning to Penglai, Luxuan did not immediately set out to search for Fangzhang Immortal Island.
For one thing, he still needed to digest the gains from the second lecture at Violet Cloud Palace and Treasure-Dividing Cliff.
For another.
Now that he knew the spatial layer where Fangzhang was located constantly shifted with the Eastern Sea's Spatial Tides, he could not chase its aura around like a headless fly.
To catch a moving target.
The simplest method was never to run faster than it.
It was to first understand exactly what pattern it followed.
At Penglai's highest point.
Luxuan sat cross-legged at the edge of the World Fetal Membrane.
An invisible thread of origin extended from him all the way to a place deep within the distant Eastern Sea.
Every few years.
That aura would undergo a noticeable shift.
Sometimes eastward.
Sometimes northward.
Occasionally, it would even abruptly vanish from his senses for a few months before reappearing in an entirely different direction.
An ordinary cultivator encountering such a situation would likely have begun to wonder whether their deductions had gone wrong.
But Luxuan grew increasingly certain.
Fangzhang really was continuously drifting through the spatial layers.
"Master."
Yunxiao stood beside him.
"These locations do not seem to be entirely without a pattern."
Luxuan turned his head.
"What did you find?"
Yunxiao raised her hand.
The Nine-River Celestial Chart unfurled on its own.
A phantom image of the Eastern Sea, formed from nine innate water veins, appeared in the sky.
Over the years, she had marked every change in Fangzhang Origin recorded by Luxuan upon the chart.
The first time was at the far eastern edge of the Eastern Sea.
The second time, farther north.
The third time, westward.
The fourth time, it returned near the first location.
Viewed separately, they seemed utterly chaotic.
But once dozens of coordinates were placed together.
An immensely vast arc gradually emerged.
"It is not moving about randomly on its own."
Yunxiao's eyes grew brighter and brighter.
"It is being pushed along by some sort of Spatial Tides between the heaven and earth of the Eastern Sea."
Luxuan understood as well.
The Great Wilderness was not truly completely still.
Especially in a region like the Eastern Sea, where the most Chaos fragments had remained after the creation of heaven and earth.
At intervals, exceedingly subtle tidal shifts would arise within the deeper layers of space.
Ordinary living beings could not sense them.
But the spatial layer containing Fangzhang Immortal Island would be carried along by those tides.
If the Eastern Sea were compared to a true ocean.
Then Fangzhang was like a ship without an anchor.
Wherever the seawater pushed it.
That was where it went.
"Find the pattern of the tides."
Luxuan smiled.
"And we will know where it will appear next."
Yunxiao nodded.
"It is only that this kind of spatial change is not something this disciple is skilled at. The Nine-River Celestial Chart can record it, but truly deducing it is difficult."
"I'll do it!"
A crisp voice came from behind them.
Bixiao had clearly been listening for quite some time.
The young girl flew directly over to the two of them.
The Space-Locking Ring around her wrist flew up on its own.
"I know about space."
Luxuan did not discourage her.
"Give it a try."
Bixiao immediately became serious.
In the past, when she comprehended the Space Great Dao, most of what she considered was how to cut through space, how to leap across it, and how to use the Golden Flood-Dragon Scissors to chase people down.
This was her first time truly deducing Spatial Tides on such a massive scale.
The difficulty was obviously on an entirely different level.
The Space-Locking Ring hovered above the Nine-River Celestial Chart.
Black Dao patterns spread outward bit by bit.
Around the sea chart, which had originally only been able to record locations, layers upon layers of fine spatial ripples gradually appeared.
The first layer of space was stable.
The second layer flowed.
The third layer showed brief dislocations.
At first, Bixiao could barely keep up.
After several dozen layers, fine sweat had already appeared on her forehead.
"So many."
She could not help muttering.
Luxuan did not help her.
He let her continue on her own.
Such an opportunity was rare.
Before they had even found Fangzhang, using the Spatial Tides outside it to let his disciple practice was not a bad idea.
If Fangzhang Immortal Island possessed intelligence.
And learned that before it had even officially emerged into the world, it had already been turned into Penglai's teaching material.
It would probably feel a strangely familiar sense of stifled frustration.
Dongwang Gong had experienced it before.
His review had not been very favorable.
For ten whole years.
Bixiao continued her deductions without pause.
The Space-Locking Ring could stabilize a small patch of space, allowing her to clearly observe how the tides within it flowed.
Meanwhile, Yunxiao used the Nine-River Celestial Chart to make records.
One was responsible for observing.
The other was responsible for recording.
Qiongxiao had initially been unable to offer much help.
Later, she simply began researching whether she could cleave through some place with a single sword strike if its space presented an abnormal obstruction.
Zhao Gongming was even more suited to the task.
The twelve stabilized layers of Myriad Heavens unfolded simultaneously.
The internal space of every layer of the world could simulate a different type of tidal change.
The four disciples gradually formed a complete cooperative system.
Luxuan sat to one side.
He watched with considerable satisfaction.
He had not even made a move himself.
Yet his disciples had already completed most of the preliminary research.
Whenever Yunxiao recorded a set of tidal patterns.
Her comprehension of the Array Dao increased.
Bixiao's understanding of spatial flow improved so visibly that it could be seen with the naked eye.
By simulating Spatial Tides, Zhao Gongming also continuously reinforced the World Fetal Membrane of the Twelve Heavens.
One stream of growth feedback after another entered Luxuan's Primordial Spirit.
Although none of them had broken through to a major realm.
This deeper understanding of the Great Dao itself, once multiplied a hundredfold in return, was no less valuable than an ordinary breakthrough in a minor realm.
Especially the Space Great Dao.
Originally, Luxuan had merely relied on his Primordial Unity Golden Immortal cultivation to forcibly perceive the location of Fangzhang Origin.
Now, however, he had begun to truly understand how the entire deep space of the Eastern Sea flowed.
Thirty years later.
Yunxiao finally drew a complete trajectory on the Nine-River Celestial Chart.
The entire path resembled an enormous ring.
Every three thousand six hundred years.
The spatial layer containing Fangzhang would complete one full circuit.
And there were still ninety-seven years until it next passed through a spatial weak point at the far eastern edge of the Eastern Sea.
"It is here."
Yunxiao pointed to the edge of the Nine-River Celestial Chart.
Bixiao raised her hand and locked onto that patch of space.
Zhao Gongming used the Twelve Heavens to simulate it once more.
In the end.
The three of them raised their heads at the same time.
Their results were completely identical.
Luxuan smiled.
"Very good."
If he had deduced it alone.
With his Primordial Unity Golden Immortal cultivation, he naturally could have found it as well.
But having his disciples complete it themselves.
Carried an entirely different meaning.
Ninety-seven years.
To the Great Wilderness, it was not much different from ninety-seven days.
It was just enough time to prepare.
But Bixiao was clearly already growing impatient.
"Master."
"Are we waiting for it to come to us?"
"Not entirely waiting."
Luxuan looked at that spatial weak point on the map.
"Since we already know it will definitely pass through here."
"We will go there in advance."
"When Fangzhang arrives."
"Lock down the space."
Bixiao immediately looked at her Space-Locking Ring.
Her eyes grew brighter and brighter.
She suddenly understood why her master had given this task to her.
It could run, could it?
Then they would seal off its route first.
Others sought overseas immortal islands through fate and affinity.
Her sect sought overseas immortal islands.
And they had already begun researching how to set an ambush and block its path.
This way of playing was rather novel.
Yet Luxuan found it perfectly reasonable.
It was great when opportunities came knocking on their own.
If they didn't—
He would go over and claim them himself.
It was all the same.
