Chu Feng was brought by Wuming Xingyun into another world within Ice Summit Peak.
This world had been forged by the Spirit World Immortal King, and the grand formation from which one could obtain the Nine Dragons Saint Robe was hidden within it as well.
To help Baili Luò break her reverse seal, Wuming Xingyun had drawn upon the power of a grand formation within this world.
That formation had not been constructed long ago — it was the work of a Saint Robe Spirit World Master.
Moreover, traces of several auras were embedded within it. Chu Feng speculated that it had very likely been created jointly by Wuming Xingyun, the Fox Immortal Empress, Liangqiu Chengfeng, and Grandmaster Long Xuan.
The construction was sealed off. From the outside, it looked like nothing more than an ordinary palace, but without the formation key, one could neither enter nor see what lay within.
Still, Chu Feng did not fear that Wuming Xingyun would do anything to harm Baili Luò.
With Wuming Xingyun's strength, if he truly wished to do Baili Luò ill, there was nothing Chu Feng could do to stop him.
At that moment, Chu Feng stood atop the peak beyond the formation's boundary, gazing toward a distant mountain range.
That place was invisible to the naked eye — even with Chu Feng's cultivation, he could not see it normally.
Despite this world having been carved out through the art of formation barriers, it was truly vast.
Yet beneath his Heavenly Eyes, Chu Feng could see what he wished to see.
There, a towering grand formation loomed. Within it, an entirely new world had been freshly carved out, and what that world actually looked like, no one knew.
What could be seen was that atop the formation floated a robe.
The robe was white and appeared quite plain, with nothing remarkable about it.
But Chu Feng knew that this unassuming garment was none other than the legendary Nine Dragons Saint Robe — forged by the Spirit World Immortal King using the dragon qi of the Nine Dragons Upper Realm.
Legend held that breaking through the formation would grant one the Nine Dragons Saint Robe.
However, the robe was protected by an invisible formation of immense power. Though Chu Feng could break through the formation, no one had yet managed to actually obtain the Nine Dragons Saint Robe.
The formation's entrance consisted of twelve zodiac statues arranged in a circle, each towering over a thousand meters tall. Their gaping maws served as the points of entry.
In other words, the formation had twelve entrances.
On the stone wall within the Fire Prison, Chu Feng had not only discovered the records describing this place — he had committed them all to memory.
He knew that the formation was extraordinarily complex. Different entrances led to different trials, each varying in difficulty, but the difficulty of each trial corresponded to the quality of the clue obtained upon completion.
Furthermore, each entrance allowed only one person at a time. Unless that person either successfully entered the formation or exited, a second person could not follow.
On the surface, the Dragon zodiac entrance appeared to be the most difficult.
The Rat zodiac entrance, by contrast, seemed to be the easiest.
But according to what the stone wall had recorded, Chu Feng knew that hidden within the Rat zodiac entrance was a secret passage — one that could only be opened through a special method.
In truth, the Rat zodiac's secret passage was the most difficult of all.
"What's the matter, kid? You interested in that Nine Dragons Saint Robe too?"
A voice came from behind Chu Feng — the Fox Immortal Empress.
She had appeared behind him without a sound. Her pair of eyes were hauntingly beautiful, the very essence of the soul-stealing charm spoken of in legends. Anyone with weak willpower would likely be captivated after a single glance.
But Chu Feng was not significantly affected.
"Senior, I am a Spirit World Master myself — how could I possibly not be interested?" Chu Feng replied with a faint smile. Then he added, "Fox Immortal Senior, is this formation truly so difficult that even you cannot break through it?"
"My, my — this is our first meeting, yet you already know who I am?" The Fox Immortal Empress looked at Chu Feng with surprise.
"Senior's fame precedes you. How could I not know?" Chu Feng said.
"So the elders of your Chu Heavenly Clan must have specifically shown you my portrait and warned you to stay away from me?" The Fox Immortal Empress said with a hint of reproach, clearly unhappy about how the world regarded her with such wariness.
"They did not. Besides, I hold no fear toward Senior — only respect." Chu Feng was not merely flattering her. As a Saint Robe Spirit World Master, the Fox Immortal Empress truly deserved his respect.
"My, my — sweet talker, aren't you." The Fox Immortal Empress chuckled, then said, "I have heard, however, that the Chu Heavenly Clan has produced a remarkable young man — the son of Chu Xuanyuan, named Chu Feng."
