Bai Qing looked at the compass on the marble, and after being discovered, the first thing that came to mind was that there should be another one, and maybe only by finding the other one could he get the clue to open the door.

She immediately lay on the floor and began to look for another pattern, back and forth after searching back and forth, and finally determined that there was only one on this five-story platform, and there was no second.

This is strange, the special thing about this compass is that the two together will form a whole, and it is impossible for there to be only one.

Moreover, this hidden is so secretive, it can only be revealed by contact with sweat (or possibly water), so painstakingly, to leave this compass pattern in this place, Bai Qing believes that it will definitely not be left only half.

The sun outside slowly rose from the sea level, rising higher and higher, and at this moment, Bai Qing found that from the top of the dome overhead, a dark red ray of sunlight shot down, and the strange thing was that this ray of sunlight seemed to have been specially designed, shooting down from the center of the giant pillar, directly hitting the lowest floor, where it was, forming a black circle of light.

What is that? Could it be that there is a second compass there?

Bai Qing immediately ran down the stairs, and sure enough, where the sun shone below, there was a triangle carved from black marble, and where the sun shone on it, there was a roulette wheel pattern that was exactly the same as the above.

It's amazing, it turns out that you can only find it during the day, when the sun shines in, and the design is really ingenious.

Bai Qing leaned over to observe the pattern on it, and saw that on the black marble, there was a circle of fine silver lines, like a delicate dial, the only difference was that the number around it was not twelve, but ten, which just corresponded to the ten stairs here.

In the middle of those ten numbers, there are two silver stars, towards two broken diamonds, dotted in a circular pattern, surrounded by a circle of delicate numbers.

One of the stars is in the middle position, and the other, some distance from it, is now between the numbers "one" and "two".

As the light intensified, the entire silver compass became clearer.

Bai Qing felt that this was because the sun was gradually moving towards the top of the building, and after a while, when the sun moved past, the pattern of this roulette wheel would gradually fade, so she had to hurry up and work out a way to open the gate.

Bai Qing stared at this roulette wheel for a while, and felt that this circle of numbers was very strange, ten numbers, corresponding to ten stairs, if so, then the fifth floor he wanted to go into, was it replaced by this number five?

The answer is clear, it must be so, but how do you open the door? Until now, Bai Qing didn't know where that door was.

At this moment, something strange happened, as the sunlight moved, the second star on the roulette wheel actually began to move.

What's going on? Is this still moving?

Bai Qing immediately stroked the star with her hand, and found that there were no stars on the marble at all, and the movement just now was just the reflection of the light.

Presumably, the pattern on this marble must have been shining by the sun to show the appearance of a star.

At this time, the star slowly moved from the numbers "one" and "two" to the position of "two", which means the second floor.

Seeing this, Bai Qing immediately rushed to the second floor, and on the platform on the second floor, he also found the same thing as the platform on the fifth floor - a protruding triangle, and then she subconsciously pasted her palm covered with sweat beads.

A few seconds later, Bai Qing raised her hand, and was surprised to find that on the triangle carved from black marble, a blue pattern clearly appeared, which was the roulette wheel she saw for the first time, this time, this pattern did not disappear with the disappearance of sweat, but kept appearing...

At this moment, Bai Qing felt a slight vibration under her feet, and hurriedly got up and hid aside, just after she moved her feet, the floor where she was standing suddenly cracked, and the fine cracks were pulled apart to both sides, the gap became bigger and bigger, and the vibration became stronger and stronger, but in just a few seconds, everything stopped, and a large square hole appeared on the original second-floor platform, Bai Qing looked down in shock, and saw that there were several steps below, and at the end of the steps, there was a silver gate.

There was the door she was looking for!

This door must lead to the second floor, Bai Qing finally understood how to use these two roulettes, and it was really very ingenious.

The door to the second floor opened, but Bai Qing didn't want to go down, her goal was the fifth floor.

Time passed slowly, the angle of sunlight gradually changed, and soon, the crack on the second floor platform returned to its original state, Bai Qing walked to the bottom and found that the second star on the compass had been moved to the third position, which was not what she wanted.

Continue to wait, until the star on the compass moves to "five", Bai Qing began to act.

She raced towards the fifth floor, found the triangle, and reached out to cover it.

A few seconds later, the same crack appeared, Bai Qing walked down excitedly, and at the end of the stairs, there was also a silver door.

Bai Qing pushed it lightly and found that the door was not locked.

Gently pushing open a gap, Bai Qing observed from the gap that there was a wide corridor outside, but it was very quiet, there was no sound, and there were no guards in sight.

In the whole square building, this is the core area of the whole building, and if you want to sneak here, Bai Qing doesn't dare to be a little sloppy.

She put her hood back on, straightened her robe, and then slowly pushed the door open and walked out.

Walking on the spacious corridor, Bai Qing struggled like stepping on thorns with every step, it was so quiet that even if she breathed, it seemed to be very loud.

Bai Qing was afraid of disturbing anyone, so she kept covering her mouth with her hands, and her feet were even more gentle.

The whole corridor is brightly lit, and every dozen meters outside, a delicate gate will appear, what is behind the door, Bai Qing does not dare to investigate, it is already difficult not to be found here.

She walked down the hallway, and just then, around the corner in front of her, there was a rush of footsteps, accompanied by the sound of talking.

"Hurry up, we need support over there in the underpass."

"I've heard that a dark ghost has invaded the underground passage, is it true?"

"The specifics are not yet clear...

"There hasn't been such an emergency in so many years, and I think something is wrong."

"Don't say it, let's go down quickly."

"Kick and stare at it."

A few heavy footsteps were about to run over, Bai Qing was startled, and at this time she didn't care about anything else, and when she saw a door at hand, she took the risk of pushing the door and getting in.

As soon as the door closed, a team of guards of the Demon Brake Club ran outside the door.

"It's dangerous!"

Bai Qing exhaled, and at this moment, right behind her, faintly noticed, there was a sharp gaze, looking at herself.
