Three days had passed since the great battle of Hundred Sects.
The Crimson Rainbow Sect had been in an excited state during these three days.
It was only after three days that the disciples formally resumed their cultivation.
Su Tong had also returned to his residence.
At this time, he was studying the small box he had obtained from the Hidden Spirit Sect.
"How exactly does one open this thing?"
Su Tong had studied it for a long time but still did not know what material it was made of or how to open it.
Even when Su Tong tried to use force, he could not damage it one bit.
Back in the Hidden Spirit Sect, he had thought about asking the Sect Master what this thing was and how to open it.
But he still felt it was inappropriate to ask about their Sect's possessions.
He could only figure it out himself.
"Roar!"
A beast's roar sounded, then a purple light swept toward Su Tong's bosom.
It was the Thunder Crystal Beast Su Tong had raised before.
"Go down, do you really think you're still the little thing from back then?"
After a few months, the Thunder Crystal Beast had grown considerably in size, and Su Tong could even ride it now.
Falling into Su Tong's embrace at this time looked a bit silly.
"Roar!"
The Thunder Crystal Beast let out a disgruntled roar.
Then obediently lay down at Su Tong's feet.
"Infusing it with spiritual energy doesn't seem to have any effect either!"
Su Tong tried infusing it with many different kinds of spiritual energy, even mixing them, but the small box remained completely unmoved.
"Could it be... mental energy?"
Su Tong hesitated for a moment, then tried using his mental energy.
A formless ripple surged out.
Then it invaded the interior of the small box.
"It's working!"
At this time, Su Tong saw the small box reveal a trace of luster on its surface.
As the mental energy seeped in, the luster grew increasingly brighter.
A moment later, a pattern actually emerged on the surface of the small box.
The pattern became clearer and clearer. After a while, Su Tong saw that a character had been outlined on the small box.
Su Tong: "..."
Looking at the character on the small box, Su Tong was also a bit helpless.
It was clearly the character "open" written in seal script.
"Click!"
At this moment, the small box made a soft clicking sound.
Then a ray of light emanated from within the small box.
Su Tong's vision blurred for a moment, and he found himself in a dark space.
"This is... the space inside the box?"
Su Tong realized that this was the space within the small box.
His spirit had entered the small box, not his physical body.
Just as Su Tong was lost in thought, a gleam of light appeared in the darkness ahead.
This gleam of light slowly began to take shape.
Rays of light, connecting together.
"What's this?"
Su Tong looked on curiously as the rays of light lined up like strands, sketching a complex pattern before him.
"This is... a formation?"
At this time, Su Tong finally realized.
The glowing strands outlined a formation pattern.
Though Su Tong did not know what purpose this formation served.
But he could clearly see its every stroke and line, and committed it to memory.
As the light continued sketching, the formation gradually took shape.
With the final stroke, the formation was complete!
A flash of light, then a scene appeared before Su Tong.
"That's Yunling Island?"
After a glance, Su Tong knew that it was Yunling Island.
As Yunling Island appeared, the formation also began to move slowly.
It approached Yunling Island, eventually merging with the island.
"It fits perfectly. So this is the Yun Ling Formation. No wonder Yunling Island can have ten times the spiritual energy, it's due to this formation."
Su Tong now understood.
Luo Zi Yin had said Yunling Island was where the Hidden Spirit Sect's headquarters was located.
So it was normal for a Sect to set up formations on their land to enhance the abundance of spiritual energy.
Just like in the Crimson Rainbow Sect, there were also such formations, only they were set up near where the Elders lived.
"A formation covering the entire Yunling Island on such a grand scale, probably only the Hidden Spirit Sect is capable of this!"
Su Tong now grasped the whole picture.
Yunling Island's wondrous nature was indeed man-made.
It was a formation set up by a Sect, to aid disciples in their cultivation.
Su Tong now understood why all the Hidden Spirit Sect disciples were at the Returning Void Realm.
Cultivating in a place filled with ten times the spiritual energy, not reaching the Returning Void Realm would make one a real failure.
As Yunling Island merged perfectly with the formation, the island vanished from sight.
A ray of light appeared again.
First a dot, then it began sketching stroke by stroke.
It actually started drawing the formation again from the beginning.
Now that he understood everything, Su Tong also withdrew his mental energy from the box.
As Su Tong's spirit retracted, the small box reverted to its original seamless peculiar object.
"The Yun Ling Formation?"
Looking at the small box before him, Su Tong was rather moved.
"Setting up a formation on the entire Yunling Island would be difficult, but setting one up within the Crimson Rainbow Sect should be doable!"
Su Tong now had a bold idea.
"But this will depend on whether Luo Zi Yin and those Elders have the guts to do it."
Setting up a formation required considerable expenditure of money and resources.
This was naturally something Su Tong could not afford.
The Crimson Rainbow Sect would have to bleed for this.
But even if they disagreed, Su Tong wouldn't say much more. After all, he might be leaving the Crimson Rainbow Sect and even the Northern Domain before long.
With this thought, Su Tong put away the small box, then called out to the Thunder Crystal Beast lying on the ground: "Let's go to the Discussion Hall, Little Thunder!"
"Roar!"
The Thunder Crystal Beast understood Su Tong's words and stood up.
Then carried Su Tong towards the Crimson Rainbow Sect's Discussion Hall.
Before long, Sect Master Luo Zi Yin and the other Elders had all been summoned over.
Although confused, they were still very courteous to Su Tong, given the immense contributions he had made to the Crimson Rainbow Sect.
"Elder Su Tong gathered so many people to the Discussion Hall, could it be that there is important business?"
Luo Zi Yin looked at Su Tong with a smile and asked.
The other Elders also looked towards Su Tong.
"Does the Sect Master and Elders know the current strength of the Sect's disciples?"
Su Tong did not answer her question, but instead asked one of his own.
"We do. There are 175 disciples at the Spirit Refining Realm, the rest are at the Body Tempering Realm!"
One Elder answered Su Tong's question.
He was the one responsible for assessing and allocating resources each month based on the disciples' strengths.
"Have you Elders ever thought of raising the Sect's disciples to the Qi Condensation Realm and even the Returning Void Realm?"
Su Tong's words were like a sudden clap of thunder that stunned everyone present.
"Of course we have thought about it. If all the Crimson Rainbow Sect disciples reached the Returning Void Realm, then our Sect could become as powerful as the Hidden Spirit Sect, reigning over the entire Northern Domain."
The Grand Elder answered Su Tong's question.
Then added: "But no one can achieve that in such a short period of time."
The other Elders also nodded in agreement.
Forget about the disciples, many of these Elders had not even reached the Returning Void Realm themselves.
Su Tong looked at the group of Elders, then said softly: "I can do it!"
A soft murmur, like a crack of thunder!
