On the first floor of the huge Secret Pavilion, there were more than 1,000 people scattered around, all of them were carefully selecting the secret formula, and no one spoke during the period, making this place seem very quiet, only the slight sound of footsteps echoed here.

After Feng Xuan had just chosen that Wind Shadow Step, after that, he silently felt dozens of mystical techniques, but he couldn't find his own, and then he looked at more than a dozen jade slips and found that it was still the same, which made him lose a little interest in the first layer of this secret pavilion, and he had a small expectation for the second layer.

And half an hour has passed at this time, and there is still half an hour, whether they choose the secret or not, Feng Xuan and they will be teleported out of the Lu on their own to end this trip.

In the deepest part of the first floor of this Secret Pavilion, there is a staircase leading to the second floor, but at the end of this staircase, there is a transparent light curtain, separating the first floor from the second floor, making it impossible for people to go to the second floor, and can only look away.

At this time, in front of this staircase, a white-clothed and extremely handsome face of Saint Jin was standing here, his sharp eyes looked up at the light curtain at the end of the staircase, and a look of helplessness appeared in the depths of his eyes, shaking his head, he turned around and left this place.

Just a dozen breaths after Shengjin left the staircase, Feng Xuan's figure slowly walked through the wooden cabinet and came here.

"This is it. Feng Xuan looked at the staircase in front of him, his gaze slowly moving upward, and finally at the light curtain that separated the first and second floors.

After a moment of silence, Feng Xuan took out a golden token from the storage ring, which was the token that Renyoko gave him to enter the second layer of the Secret Pavilion.

As the golden token was taken out, a golden light immediately rushed out from it, shooting into the light curtain at the end of the staircase.

At this time, the light curtain violently rippled endlessly, and soon this light curtain gradually faded until it disappeared completely.

At the first moment when the transparent light curtain disappeared, outside the Juezang Pavilion, the two elders of Yin and Yang on the left and right of the huge wooden door both opened their eyes at this time, but then the two of them closed their eyes again, and their faces did not change in the slightest.

Almost at the moment when the transparent light curtain dissipated, Feng Xuan rushed up the stairs as fast as lightning on his toes, and rushed into the second floor of the Secret Hidden Pavilion, and the transparent light curtain also reappeared at this time, blocking the first and second floors.

The second floor of the Jue Zang Pavilion, which is much smaller than the first floor, hundreds of jade slips that emit bursts of powerful spiritual yuan fluctuations float quietly in mid-air, there are no wooden cabinets here, only these jade slips with white light diffusion, and there is only a staircase leading to the third floor.

Feng Xuan walked among the hundreds of jade slips that emitted powerful spirit element fluctuations, he looked at a jade slip in front of him that emitted more powerful spirit element fluctuations than the other jade slips around him, reached out and took it in his hand, and the amount of soul power also probed into it at this time.

"Tiger Roar Jue, Late Ground Level Xuan Jue, Attack Xuan Jue, the sound of a tiger roar from the mouth, shocking people's hearts, collapse consciousness, exclusive sonic attack, extremely powerful. ”

"It has reached the late stage of the prefecture level, and it is also a rare sonic attack, this kind of mystery is specialized in people's consciousness, and it will not have a direct impact on the body, which is unguardable," Feng Xuan looked at the jade slip filled with white light in his hand, and his eyes showed a strong brilliance.

"Just choose this mystery...... Huh?" Feng Xuan looked around, and before he finished speaking, his eyes were staring at one place a little strangely.

The hundreds of jade slips floating in the air in the second layer are all emitting bursts of soft white light, but one of the jade slips has no white light emitted, and there are bursts of black light on it, making this jade slip unique and particularly conspicuous among the hundreds of jade slips.

This unique jade slip, not only has black light scattered on it, but also a very small black lightning wandering in this jade slip, a subtle sense of destruction quietly dispersed on this jade slip, but it did not disperse far away, just within a zhang range, only a pity that there are a few cracks on this jade slip, almost through the entire jade slip, making this jade slip seem to collapse and disintegrate at any time.

Feng Xuan's eyes were looking at this jade slip, when he first saw this jade slip before, his eyes lit up, but when he saw the cracks on the jade slip, the light in his eyes quickly became dim like a deflated ball.

However, Feng Xuan still walked towards the broken jade slip, he wanted to know why this jade slip was like this, and it was still placed in the second layer of this secret pavilion.

Looking at the jade slip in front of him that emitted bursts of black light and black lightning, and looking at this jade slip so closely, in addition to those few big cracks on this jade slip, there are also small cracks, like a spider web covering the entire jade slip, which makes this jade slip seem to be completely turned into ashes if you touch it slightly.

Looking at the broken jade slip in front of him, Feng Xuan's eyes were a little confused at this time, as if there was a force in his heart pulling him, making his hand gently move to the jade slip in front of him, and holding the broken jade slip under his confused eyes.

"Bang!"

The black mangyu was shattered and turned into flying ashes, and when it turned into flying ashes, a small black lightning bolt rushed into Feng Xuan's eyebrows and entered his sea of consciousness in a flash.

And the confusion in Feng Xuan's eyes gradually dissipated at this time, and slowly turned into clarity.

"How so, is this another recipe I chose? And it seems that this recipe can't be put back. Feng Xuan felt the tiny black lightning in the sea of knowledge, and said blankly.

Coupled with the Wind Shadow Step that Feng Xuan chose from the first layer and the Tiger Roar Technique in this layer, plus the black lightning in this Broken Jade Slip, he had already chosen three kinds of Mystery Formula, and Yin Lao, one of the two elders of Yin and Yang in front of him, said that one person could only choose two kinds of Mystery Formula, and he could not go any further.

Now Feng Xuan has only one of the secret tricks, and the black lightning in the sea of his consciousness is estimated to be unable to get it, so he can only choose one of them between the Wind Shadow Step and the Tiger Roar Technique.

With a flip of his palm, two jade slips emitting bursts of white light appeared in Feng Xuan's hands, looking at the two jade slips in his hand, Feng Xuan didn't know which one to choose, whether it was the body technique or the sonic attack technique, it was what he was lacking now.

However, just when Feng Xuan was struggling with which kind of secret trick to choose, an hour had passed, and the time for choosing a secret had arrived, and a black hole appeared out of thin air, directly sucking Feng Xuan's entire body into it, which had not yet reacted, and disappeared in a flash.

The same situation did not only appear here in Feng Xuan, in the first layer of the Jue Treasure Pavilion, a huge black hole appeared directly, and the suction exploded, whether it was the person who chose the Xuan Jue or not, they were all sucked into it, and in the blink of an eye, the thousands of Dao people here were all sucked away, and slowly disappeared as the huge black hole flickered slightly.
