Under the moonlight, a carved golden dragon on the wooden box flashed with golden light, and at a glance, I knew that it was a precious thing, but I didn't understand what Xiao Lianshan meant by suddenly giving me this wooden box, I looked at Xiao Lianshan in surprise and found that he was concentrating on polishing the silver gun in his hand.

I hesitated for a moment to open the wooden box on the table, which was a golden gold pen, looking at the style should be old and the nib of the pen has a red mark, presumably this is the thing used by the emperor, next to the gold pen there is a roll of yellowed rice paper, I carefully took it out of the wooden box, slowly unfolded it on the stone table, and frowned at a glance.

On the rice paper is a painting, and it is a very strange picture, at the top is a fierce white tiger around a silver disk, and on the left side of the picture is a mouse and a horse's tail connected, but each looking ahead, on top of the mouse and the horse is a dragon rising into the sky, and below the picture is a star chart that I can't read.

"Dad, this ...... What is it? "I watched it for a long time and asked Xiao Lianshan in confusion." What are you doing with this all of a sudden? ”

"You're in the right place, but you're in the wrong place." Xiao Lianshan looked at the silver gun in his hand very calmly and said lightly. "Genghis Khan's treasure should be related, but the entrance is not what you thought before, I sent someone to dig in, but I didn't find the entrance to the treasure."

"Ah, you sent someone in there to dig in?" I looked at Xiao Lianshan in shock.

"There are some things that are much easier for me to do than you do, and it's not like I haven't done these things before." Xiao Lianshan smiled faintly and replied disappreciatively.

"Is there nothing in half the room?"

"I didn't find the entrance, but I dug up this wooden box in your hand in the ground of half of the room, and it must be related to Genghis Khan's treasure." Xiao Lianshan replied calmly.

"This wooden box was found under half a room!" I stood up and looked excitedly at the things on the stone table.

"The gold pen and pattern in the wooden box should be the lines left by Zhu Di." Xiao Lianshan turned his head to look at me, pushed the wooden box in front of me and smiled faintly. "I already have my own memories, so let your memories start here."

I woke everyone up early the next morning, took out the contents of the wooden box and put them in front of them, and when I learned that Xiao Lianshan actually sent someone to dig out half of the room, I was as stunned as I had just learned the news, but I thought about it later, Xiao Lianshan's past in this life should be very exciting, black and white have friends he knows and makes deeply, maybe what is difficult to do in our eyes, but it is very simple in his eyes.

The key now is to untie the thread in the wooden box as soon as possible, Nie Haoran has not much time left for me, and there are still nine days left for the next cloudy day to come.

We studied it for two days without any progress, and we carefully checked the gold pen many times, although it was precious and valuable, it was just a gold pen, and there was no mechanism or mystery in it, and we did not find a word on these two things.

"What is this, playing dumb riddles? There are no hints, what does Zhu Di want to prompt with a pen and a painting? Gu Xiaoxiao rubbed her eyes tiredly.

"There are dragons, tigers, horses, and rats in the painting, and these things should be a metaphor for something." Han Yu said tiredly and limply on the chair.

"Nangong Yi, are you well-informed, do you have any allusions about the white tiger and the disc?" I asked anxiously.

"No, I've thought about it over and over again, and there's really no record of the two." Nangong Yi shook her head and replied.

"White Tiger...... The white tiger, in Taoism, is one of the four elephants of the Seven Stars of the West, the seven Western Houses of the Twenty-eight Houses, and its image of the Tiger, located in the West, belongs to the gold, the main killing, the color is white, and the name is the White Tiger. Han Yu slowly straightened up and said thoughtfully. But I know exactly what the disc is. ”

"The Western Seven Nights......" After slowly looking at the painting again, he turned around and walked to the side, pushed open the window, looked up for a long time, and suddenly turned his head and pointed to the night sky and said to us. The disc refers to whether this is the case. ”

We all turned our heads to look at the past, and a bright moon hung in the sky like a round silver platter.

"That's right, why didn't I think of this, the White Tiger is the Lord of the West, and the disc of the West of course refers to the moon!" Gu Xiaoxiao's eyes lit up and said happily. "The white tiger holding the moon should be pointing to the direction, and it also determines the direction of this painting."

After hearing this, Nangong Yi immediately took out a clean white paper, marked the south, south, north, and west on it, and then copied the star map under the rice paper, the only thing we could be sure of before was the distribution map of the stars on this painting, but because there was no direction, she couldn't judge what the stars were, and after Nangong Yi copied it, she looked at it for a long time and said happily.

"This nakushatra chart is the constellation of Ursa Minor!"

We gathered around and saw Nangong Yi connect the transcribed stars with lines on a white piece of paper and mark the directions, and sure enough, it was a shape similar to that of a bear.

Gu Xiaoxiao suddenly saw the pen in Nangong Yi's hand, and with a shocked face, she slowly drew lines on the paper that we couldn't understand, and after she finished drawing, a complete circular star map appeared in front of us.

"My grandfather taught me to see, and the most important thing is this nakshatra map, according to the direction marked in the original painting, this nakshatra is located in the north." Gu Xiaoxiao took a pen and drew a circle on one of the stars, and then told us seriously. "This star is called the North Star, the most respected star of the sky, and the center of its new star and sky, the fortune of the sky is endless, and the stars do not move, and the stars arch in their place."

"North Star!" I was surprised to say it.

"This constellation chart is Ziweiyuan, one of the walls." Han Yu is also quite proficient in star images, and continued to say to us. "Ziwei Yuan is the middle wall of the wall, located in the center of the North Heaven, so it is called the Middle Palace, it is the place where the Emperor of Heaven lives, with the north as the center, there are fifteen stars, divided into two columns of the left wall and the right wall, called Ziwei Yuan in the north of the Beidou, the left and right ring columns, the image of Yiwei."

"The North Star is also known as the Purple Palace...... The constellation diagram on this painting is actually an allusion to the Forbidden City! Gu Xiaoxiao said with certainty.

"This gold pen and painting should be left by Zhu Di, it should be a line related to the treasure of Genghis Khan, and the painting mentions the Forbidden City again, presumably the treasure and the remains of Genghis Khan must be under the Forbidden City." I said happily.

"But even if we know that the stars in this picture are alluding to the Forbidden City, and the white tiger hugging the moon is a hint of direction, then what does this soaring dragon and the rat and horse connected to the tail below mean?"

"Since the white tiger is hinting at the direction, will the dragon also mean the same?" I asked, a little confused.

"It shouldn't be, the white tiger can already mark the direction of this painting, no need to do more, the green dragon in the east of the four elephants, corresponds to the white tiger, and it seems that it does not match the position in the painting." Han Yu shook his head and said surely. "And rats and horses aren't directions."

"Under what circumstances do rats and horses get together?" Nangong Yi also muttered to herself in confusion.

"There are rats and horses in the zodiac, the rat is the rat, and the horse is the noon horse, which represents different years, and the two cannot appear at the same time, if there is, it is also noon opposition, and there will be no connection." Han Yu shook his head and replied.

We walked up and looked at it for a long time, and suddenly took a pen and drew a line on the white paper, and we were surprised to find that the line through the rat's head and the horse's head was impartial and just crossed the north star, and the rat's head was just facing the north star.

"Here the rat and the horse are connected, which should refer to noon, and the ancients thought that due north, noon is due south, which is why the rat's head is exactly aimed at the north star in the picture, and the noon here is also marking the direction." Said calmly.

I suddenly frowned, slowly buried my head and looked at the painting in front of me, muttering noon repeatedly, and then said with some surprise.

"The constellation diagram is a metaphor for the Forbidden City, judging from the rats and horses in the picture, it is just on the north-south axis of the Forbidden City.

"What do you mean?" The others asked in unison.

"There is a gate in the Forbidden City that happens to be on the north-south axis, and it is located at noon."

"Noon!" Nangong Yi suddenly realized, pointed to the painting, and said excitedly. "The noon gate is the main gate of the Forbidden City, the noon is called the noon gate, the mouse and the horse are connected together, the north-south symmetry is exactly the noon, and then the Forbidden City is linked to the star map, which should refer to the noon gate!"

"Does it mean that Genghis Khan's treasures and remains are hidden under the noon gate?" Han Yu frowned and said with some surprise. "If that's the case, then it's a big trouble, it's a very prominent location in the Forbidden City, who dares to dig down there."

"It shouldn't be the noon gate, imagine that Zhu Di will also enter it, his entry and exit of the noon gate will inevitably attract the attention of many people, the secret of the treasure will be leaked sooner or later, the passage to enter the treasure should be elsewhere, there should be other reasons for the noon gate here." Nangong Yi shook his head and said.

"If we are right, then we will unravel the meaning of everything in this painting, and all that remains is this soaring dragon between the white tiger hugging the moon and the noon gate." Gu Xiaoxiao pursed her lips and took a few steps back and forth, and said thoughtfully. "Maybe we won't be able to fully grasp the meaning of this painting until we unravel the dragon."

"There is a dragon ...... on the noon gate"

Nangong Yi pondered for a moment and then said to us that the Noon Gate is the main gate of the Forbidden City. The east and west north city platforms are connected, surrounding a square square, the north gatehouse, facing nine rooms, the top of the yellow tile palace with heavy eaves.

There are ten rooms on the east and west city platforms, row up from both sides of the gatehouse to the south, the shape is like the goose wings, also called the wild goose wing building, there is a heavy eaves to gather the spire que pavilion at the north and south ends of the east and west wild goose wing building.

And the majestic noon gate, like a mountain embrace, five peaks protruding, majestic, but there is no dragon pattern on the noon gate.
