Although the rift had appeared, the old Daoist did not immediately activate the formation.
Instead, his formation continued for quite some time—even longer than it had taken to tear open the rift in the first place.
Though suspicions arose in everyone's minds, no one dared to ask. After all, whether the Source of the Dragon Vein could be opened, and how it would be opened, all depended on the old Daoist.
They could only choose to trust him, and trust him they did.
During this time, naturally no one sat idle. They tried every means possible to peer through the rift and catch a glimpse of what lay inside the Source of the Dragon Vein.
But the rift remained pitch black. No matter what methods they used, they could not see a thing within—as though the rift were merely decorative and didn't actually lead to the Source of the Dragon Vein.
Thus, after a full six hours had passed, the old Daoist finally turned his gaze toward Chu Feng and Dragon Xiaoxiao.
"You two, go in. Chu Feng—just do as I told you."
The old Daoist said.
"As you command."
Having said this, Chu Feng brought Dragon Xiaoxiao and entered through the rift.
However, after passing through the rift, Chu Feng and Dragon Xiaoxiao were startled to find that they had entered a pitch-black world.
Even after passing through the rift, they had clearly not actually entered the Source of the Dragon Vein.
Moreover, some force had sealed them here.
If they wished to continue forward, they would have to break through this force.
Fortunately, within the force blocking them, faintly flowing runes could be seen—that was the clue.
So Chu Feng didn't delay. He immediately released his Mental Power to sense and analyze the contents of those runes.
But after sensing them, Chu Feng furrowed his brows.
He found that the contents of the runes were not difficult to comprehend at all. In fact, he grasped their meaning with ease.
What blocked them was a Yin-Yang Barrier.
To break through this Yin-Yang Barrier was actually quite simple—the runes already provided a method for doing so.
It was as if a locked door stood before you, yet hanging on the wall right beside it was the key to the lock.
But if one were to call it simple, it wasn't exactly simple either.
Breaking this formation required two people to cooperate in setting it up together.
But mere cooperation wouldn't do—they actually had to stand bare before each other.
This left Chu Feng quite embarrassed. What sort of ridiculous condition was this?
If he told Dragon Xiaoxiao about this, she would surely think he was some kind of pervert.
Still, Chu Feng couldn't help but glance at Dragon Xiaoxiao.
Though it was pitch black here, Chu Feng could still clearly see Dragon Xiaoxiao.
One look was all it took. He found that Dragon Xiaoxiao's little face was flushed red, her head lowered in silence.
It seemed she had sensed his gaze, because her already crimson face turned even redder.
"Uh..."
"Princess Xiaoxiao... did you also discover the method to break the formation?"
Chu Feng asked.
"Yes."
Dragon Xiaoxiao nodded.
"This method is far too strange. It must be some kind of prank."
"Let's just set up the formation the normal way and see if it works to break through."
Chu Feng said.
"Alright."
Dragon Xiaoxiao agreed.
With their minds made up, the two didn't hesitate. They immediately began setting up the formation based on what they had comprehended here.
Sure enough, once the two combined their efforts, this formation proved to be quite extraordinary.
