The formation laid out by that old Daoist was extraordinarily powerful.
First, it spanned multiple starfields and countless worlds, yet allowed travel between them in a short amount of time. In other words, this grand formation was a teleportation array whose speed far surpassed that of ancient teleportation formations — by several times over.
Its only drawback was that, despite covering multiple worlds, its reach was ultimately limited. Not every location could be accessed through it.
But possessing such terrifying speed was already remarkable — even inconceivable.
And the reason it could achieve this was not merely due to the old Daoist's brilliant arrangement of the formation. More importantly, it was backed by an enormously powerful energy source.
That source was the shell of the Dark Demon God.
The Sacred Deer had once said that the Dark Demon God wielded the power of space.
Perhaps it was precisely because of this that the formation had been granted power exceeding that of ordinary teleportation formations by several times.
Of course, even with teleportation, one could not go wherever one pleased. One had to first reach the main formation, and then, from within it, activate the barrier gate leading to a desired destination before stepping through.
The place where Chu Feng currently stood was precisely the main formation.
As for the barrier gates scattered across various locations, some were merely hidden gates, while others were concealed within ancient ruins. Those ruins were all the handiwork left behind by Zhuge Yuankong.
This formation was far too powerful and far too extraordinary, making it no easy task to control.
Though Chu Feng had grasped the formation's power, he had not yet fully mastered it. As such, he could not use the power here completely at will.
Teleportation was one such example. To select the specific barrier gate he wanted from among those scattered throughout the world, he still needed to search through them slowly.
Chu Feng had originally been searching for the barrier gate leading to the Upper Realm of Reincarnation. But during his search, he stumbled upon a different barrier gate — one connected to a set of ruins.
And within those ruins, he detected the figures of Long Xiaoxiao and her companions.
It was not just Long Xiaoxiao — Long Shengbu, Long Nanxun, and Elder Rui Yun were all there as well.
As for the two genius Spirit World Masters, Chen Guang and Yue Yang, they were nowhere to be found.
Because Chu Feng had taken control of the main formation, and the power of those ruins was also tied to it, there was a definitive connection between them. So despite the ruins being immensely far away from Chu Feng, he could still sense everything within them.
Throughout the entirety of those ruins, there was no trace of Chen Guang and Yue Yang's auras.
The two of them might have perished, or they might never have entered those ruins in the first place. But neither possibility was Chu Feng's primary concern. What mattered was that Long Xiaoxiao and her group had already ventured into the deepest part of the ruins.
Though Chu Feng had long known that Long Xiaoxiao had sought his help specifically to break through a formation, he had not expected that the formation they needed to breach was one left behind by the old Daoist.
Of course, they had no idea who the old Daoist was. They only knew the name Zhuge Yuankong.
At this moment, they had already entered the depths of the ruins, and from all appearances, they were not in any immediate danger.
The reason Chu Feng felt their situation was perilous, however, had to do with one other figure.
It was a woman. She appeared middle-aged, with a dignified appearance and an extraordinary bearing — the kind of woman who radiated an overwhelming presence.
At this moment, this woman wielded an incredibly powerful force within her body.
It was the power of those ruins.
In simple terms, this woman had already seized control of the ruins.
If that were all there was to it, it would not have been enough to make Chu Feng worry. After all, when breaking through ruins, if a Spirit World Master could seize control of the main formation's power, they would typically do so.
But what Chu Feng could sense was that this woman was using the power of the ruins to drive an offensive formation — and that formation's might was formidable.
Yet there were clearly no enemies inside those ruins, so why would she deploy such a powerful attack array?
The only possibility Chu Feng could imagine was one: this woman was very likely planning to act against Long Xiaoxiao and the others.
"Miss Yu Ting, wait here for me for a moment. I'll be right back."
After saying this to Yu Ting, Chu Feng opened a barrier gate that led to those ruins and immediately stepped through.
Though Chu Feng had gained control over the formation's power, he had not yet achieved full mastery. To help Long Xiaoxiao and her group now, he needed to enter the ruins in person before he could harness the power within.
But even though the Dark Demon God's power was immense and could bridge vast distances in a short time, it still required some time to do so. Chu Feng had to set out for the ruins right now — otherwise, if he delayed too long, he might not be able to save them.
The noble woman who had seized control of the main formation's power within those ruins was none other than the renowned Insight Celestial Master.
This Insight Celestial Master not only possessed the art of prophecy, but she was also a Sacred Robe Spirit World Master who had comprehended the fourth level of the Dragon Transformation.
The fourth level of the Dragon Transformation — that was power comparable to an eight-rank Martial Emperor.
But the Insight Celestial Master's prowess was not limited to the ways of the Spirit. Her cultivation was also extraordinarily formidable.
She was a nine-rank Martial Emperor — a peak-level Emperor.
