Only Zhu Haoying reacted.

"Don't you say what you saw on the map when the fire fold was lit just now, you still want to use fire? No way!" Zhu Haoying said.

As he spoke, Zhu Haoying reached out to snatch the animal skin scroll back.

"Don't make trouble! Let go! Senior Sister Deng!" Bai Lingfeng's cultivation is too low, he can't rob Zhu Haoying, but fortunately he has a good sister.

"Okay, you calm down first and listen to Senior Brother Bai. Deng Qiushuang clapped her hands and glanced back at Zhu Haoying, who was smashed to the ground by herself.

"There was a moonlight shining in here just now, and I saw the mirror we had when we first teleported in, still reflecting the light. It's just that the light of the moon is too soft, and it only illuminates part of the place. Bai Lingfeng said.

"And then?" Zhu Haoying also breathed a sigh of relief when he saw that the little door master was not planning to burn his map with fire.

"I tried the mirror when I came in just now, and it was sunlight, and no matter what angle I set it to, as soon as the sunlight hit the mirror, the whole stone room was lit up. Bai Lingfeng continued: "But just now, I saw that the light reflected by the moonlight through the mirror was very concentrated. ”

"If you look at the mirror, it's the only one in the room that can be reversed, but if it's just lighting, you don't need to move it at all, just fix a position and wait for the sun to come out every day. Bai Lingfeng said.

"So...... Do you think it's a pointer?" Zhu Haoying's breathing was a little short.

"Do you think that's right?" Bai Lingfeng touched Sissi, who had never left his arms.

Sissi tilted her head sideways in anguish.

"I'll try it in the past!" Zhu Haoying said, and her figure slowly dissipated.

"In a hurry, he even used the body method. Bai Lingfeng said.

"It's his treasure map, of course nervous. Deng Qiushuang said with a smile.

Zhu Haoying came to the bronze mirror that could be rotated, he tried it, but he didn't expect it to be quite heavy, that little yellow dog could kick it with one kick?

The true qi in his body is running, and his cultivation in the Refining Pulse Realm can easily turn.

Sure enough, as the little door master said, the moonlight was very soft, and although it could not illuminate the entire stone room, it could concentrate into a beam of light on this mirror.

But with the intervention of the surrounding fire folds, the light of the moon was obscured a lot.

When Zhu Haoying turned the mirror, the stones on the iron shelf made a grinding sound when they turned, which was especially loud in this stone room.

At this time, all the disciples of the Divine Sword Sect in the room looked at him.

"You are not allowed to come up and touch this mirror!" Zhu Haoying stretched out his index finger with one hand and held the iron frame as a fulcrum with the other, and turned around while saying this, pointing everyone in.

It's just that he's a bit silly right now.

"I suddenly felt that my father had made the right decision to demote him to a core disciple. Bai Lingfeng said.

Zhu Haoying returned to Bai Lingfeng's side, smiled happily, and said, "Little Sect Master, I didn't expect you to really have archaeological potential, do you want to consider joining our organization? But let's talk about these later, what should we do next?"

"I don't know. Bai Lingfeng shrugged and said.

"Then you just said you knew?" Zhu Haoying said.

"It's all said, that's all. Bai Lingfeng said.

Zhu Haoying: Convex (艹艹)

"Senior Brother Zhu, can you show me this animal skin scroll?"

Zhu Haoying glanced at Yue Xiaoyang, along the way, this little witch has always been very low-key, and she also knows how to be measured. Even he almost forgot why Yue Xiaoyang became famous.

"Yes, if you do find a treasure, you have a copy of it. Zhu Haoying nodded.

"Then I'll thank Senior Brother Zhu in advance. Yue Xiaoyang thanked him directly, without bargaining, let alone asking how much there was.

With his approval, Bai Lingfeng handed over the animal skin scroll to Yue Xiaoyang.

After Yue Xiaoyang got the animal skin scroll, he opened it and spread it on the ground.

In the middle of the map is a large tree and the flaming bird is the most eye-catching, very eye-catching.

But when Yue Xiaoyang's first reaction when he saw this map, he knew that this map was definitely more than just the thing in front of him.

Because as Bai Lingfeng said before, the animal skin scroll was very large, but the things painted only accounted for about half.

Yue Xiaoyang saw at a glance something that Bai Lingfeng and Zhu Haoying hadn't mentioned before.

She pointed to the circular pattern in the upper right corner of the map and asked, "Is this the sun?"

"yes, this should be for people to get their bearings, and many maps will have it. I've also checked it, and the position of the sun on the map is exactly to the east. Zhu Haoying said.

"Well, I thought so too, so I didn't say it. Is there any problem?" Bai Lingfeng said.

"It's just that I don't think there's a need to waste such a big position to make people determine the direction. Yue Xiaoyang said.

"Is that because people didn't have a compass in the past, they all relied on the sunrise to discern the direction?" Jinbao said, now that Sister Xiaoyang is presiding, he finally dared to interject.

"No, Senior Sister Yue, you reminded me!" Zhu Haoying said suddenly.

"Looking at your reaction, Senior Brother Zhu, people at that time should have already known how to use the stars to discern the direction. Yue Xiaoyang's tone was very calm, obviously he had already guessed.

"Then what does this sun mean?" Bai Lingfeng also fell into deep thought.

Yue Xiaoyang groaned for a moment. Suddenly she looked up, stood up suddenly, and without saying a word, immediately walked under the movable mirror, spread the map on the ground, and reached for the mirror.

"Wow, it's really heavy. Come and help me. Yue Xiaoyang pulled the mirror with both hands, and the mirror just turned slowly.

Bai Lingfeng had already followed when she got up, and at this time, he just stretched out a hand, and the mirror easily turned.

"My strength seems to have increased again compared to when I practiced swords, although it was not obvious. Bai Lingfeng said in his heart.

"Shine the moonlight on the map. Yue Xiaoyang said.

Bai Lingfeng turned the angle of the mirror and found that the bracket of this mirror could actually rotate in all directions without dead ends, and he could easily shine a beam of moonlight on the map.

Immediately changed on the map!

I saw that the icon representing the sun in the upper right corner slowly disappeared, and then the flame bird above the tree also slowly disappeared, but the egg on the tree still existed.

As they begin to disappear, new images appear on the map!

Under the light of the moon's beam, a crescent-shaped pattern slowly appears in the upper left corner of the map. Based on the sun pattern in the upper right corner, it is conceivable that this represents the moon.

When the moon pattern appeared, there were many circles on the map, and next to each of them, there would be an icon.

"Sure enough, there are other secrets. Zhu Haoying snatched the animal skin scroll, studied it carefully, and said while looking at it: "There is no reason, I have also seen this map under the moonlight before, and there was no change at that time." ”

Yue Xiaoyang patted the iron shelf beside him and said, "Maybe it's because the light of the moon is not enough, the mirrors in here should have been specially refined." For sunlight, it is diffusion reflection, and for the moon, it is condensation and absorption. ”

When Zhu Haoying heard this, she immediately stood up and went to check the mirror.

This time he finally saw that the mirror surface was smooth, but there were many hard-to-find lines inside, and these lines looked like countless hexagons neatly arranged.

Instead, the mirror is a combination of these tiny hexagons.

"Well, I'm ...... I can't even find it like this, it seems that the little door master and Senior Sister Yue are more suitable for archaeology than me. Zhu Haoying was a little depressed.

"I'm not going to rob graves. Bai Lingfeng said.

"We don't usually bring out the contents of the tombs, we just want to understand the previous civilizations that were drowned in the long river of history. Zhu Haoying explained.

"I'm not going to dig people's graves. Bai Lingfeng said.

Zhu Haoying: (╯‵□′)╯(┻━┻

Bai Lingfeng felt that he was a little bored, but he wanted to target Zhu Haoying, seeing him let himself go everywhere like this, it was no longer interesting for him to mess around.

He took the animal skin scroll from Zhu Haoying's hand and saw the many new circular patterns on the map.

And on the sides of the circle, there is a small rectangle, which is filled with color.

And the rectangle on the side of each circle is in a different position.

"These rounds...... What does it all mean, why does it look a little familiar?" Bai Lingfeng said.

"Well, you are. Didn't you look at anything when you first came in? Look at your feet. Yue Xiaoyang was really speechless.

Everyone looked at their feet, and sure enough, they saw a circular pattern on the ground, with an iron frame under the mirror as the center, and the diameter should be less than two meters.

And on the side of this circle, there is a rectangular stone. He gently turned the mirror, and the rectangular stone moved.

Bai Lingfeng immediately remembered that he had seen it when he had just been teleported in, and he thought it was a certain formation.

No wonder it looks so familiar, the pattern on the ground is the same as the circle pattern on the map.

"I'll take a look, it's supposed to be like this......" Bai Lingfeng thought for a moment, constantly turning the mirror, but his head looked at the rectangular stone below.

The stone actually moved along the edge of the circle.

"Hey, please. Brothers and sisters, please put out all your fire. Bai Lingfeng said.

The surrounding disciples of the Divine Sword Sect noticed that the little sect master was doing something early in the morning, but they didn't come forward to ask.

Because they don't know the temper of this little door master at all, although they seem to be quite polite, but this harmless appearance in front of people is the most terrifying.

Some disciples even saw that Yue Xiaoyang and the three of them were so familiar with the little sect master, and their hearts sank.

With the infamous deeds of this trio...... Do you have to get back those things that were lent out? Or should you just leave those things that were cheated before?

The little door masters all spoke, and they were still happy to cooperate with such a small request.

Soon, all the fire folds were extinguished.

The moonlight shone through the small holes in the upper room, and it was a milky white transparent light, like a thin veil. Although it was very faint, all the people present were monks, and the surroundings were only a little dim, and they could see.

Through the special material of the mirror, the reflected moonlight is more condensed and bright, forming a beam of light.

"I'll take a look...... It should be calibrated like this. Bai Lingfeng referred to the first pattern on the map, and then looked at the rectangle on the ground, and the two cooperated to rotate the mirror.

The light refracted by the mirror that Bai Lingfeng rotated, through the refraction of other mirrors, finally reflected the moonlight at the bottom of the 10,000-year-old giant tree, that is, the moonlight was reflected on those holes.

And the light refracted by these moonlights, when they find the hole, can actually illuminate the entire hole clearly.

Because every time Bai Lingfeng rotated the mirror, the trajectory of refraction between the mirrors was different.

There were so many mirrors around, as long as Bai Lingfeng turned slightly, the refracted light would jump to different mirrors, so when it finally refracted to the hole on the top, the size of the light was also different.

But it can just illuminate the entire hole.

When Bai Lingfeng got the hang of it, he turned the mirror according to the first pattern.

When he stopped, the moonlight was also accurately refracted through the mirror to a tree hole.

Immediately, everyone was stunned.

"Isn't this the empty mouth we just escaped?" said someone around us.
