Chapter 99:

Such an important thing, how dare the guards do it.
So Li Cheng looked at the three princes, and the three princes would not dare to get this map if they didn't speak.
Of course, apart from the three princes, it depends on what Qing prince thinks. This matter originally had Yan Guo's share, so naturally I have to ask people's opinions.
The third prince twisted his eyebrows and pondered for a while. He thought of Li Chengze's cleverness and always thought of places that others could not think of. He must be confident in his heart to say this. After all, no one would dare to joke with this map for no reason. If you destroy the map, it will be a crime.
So the third prince said: "You can tear it down."
After speaking, the third prince turned his head to look at Prince Qing, and said, "What does the prince mean."
The three princes agreed to what the Lord Qing could do, and besides, they were indeed in a situation where they could not find a way.
The man had been walking since he took them into the mountain. At first he saw a place similar to the entrance of a map, but he didn't expect that he would be wrong after walking in. The road conditions were exactly the same, and he couldn't follow the route on the map at all.
Li Cheng seems to have discovered something right now, how can he object? Anyway, even if no useful information is found at the end, the map can still be used.
So Lord Qing nodded.
So, the guard got the order and took the map, and Li Cheng handed him the Dragon and Phoenix Dagger.
The dragon and phoenix dagger blows and breaks the hair, the size is right, and it must be much better than the guard's own long knife.
The two people laid the map flat on the ground and pulled the map tightly, and then one person started using the dragon and phoenix dagger bit by bit to slowly roll the thin sheepskin into pieces.
Fortunately, there is this dragon and phoenix dagger, otherwise it may not be able to separate this thing.
Originally the guard had a solemn expression, but he was relieved after he started. The Dragon and Phoenix Dagger was much easier to use than he thought.
With the last cracking sound and a crash, the parchment rolls were completely separated into two pieces.
The three princes and the Yan National Day prince grabbed one side at the same time, and when they held it in front of them, there were surprises in their eyes.
"Sure enough, there is a mystery! It turns out that the real map is inside!" The three princes were full of excitement, but his expression changed in the next second, "Is a piece missing?"
Others leaned over and saw a blank bar in the middle of the map.
Prince Qing said in a deep voice, "It's the same with me."
The third prince went to see Li Chengze subconsciously and asked, "Chengze, why is this?"
Li Cheng was not surprised, his complexion remained as usual, he only said one sentence: "You may bring charcoal."
Naturally they brought them, not only this, because it is not easy to enter Yuershan. They brought a lot of things, which may be used.
Soon a guard brought something in front of him, and also found a large flat and smooth stone so that he could write on it.
"Dragon and Phoenix Dagger." Li Cheng continued.
The guard once again handed the dragon and phoenix dagger to his hand.
Everyone stared at him to see what he was going to do.
I saw Li Cheng drew the dragon and phoenix dagger out of the scabbard, and then laid it flat in front of him, watching the dragon-shaped pattern on that side, and began to draw on the paper, coming and going, less than a quarter of an hour, appeared on the paper A map.
Everyone opened their eyes wide, wondering how he drew it.
Before he had time to get an overview, Li Cheng finished painting this side, changed another side, and continued painting facing the phoenix pattern.
Finally, when the drawing was finished, two topographic maps appeared on the two sheets.
The dragon and phoenix dagger was returned to Prince Qing, and Li Cheng pointed to the two pictures and said, "This is the missing part of the two parchment scrolls."
The three princes and Qing princes are all looking at that part of the map.
Ju is very curious, and invariably asked: "How did you draw it."
Lord Qing didn't believe in evil, so he pulled out the dragon and phoenix dagger and looked at it repeatedly. No matter how he looked at it, he couldn't see the missing two parts of the map.
Li Cheng sighed and said, "Don't look at the black dragon pattern, just look at the white place."
This is the visual surprise caused by the color. For example, in a picture, the dark part will automatically move forward and the light part will move back.
The dagger body of this dragon and phoenix dagger to escape the summer heat, the dragon and phoenix patterns all over the body are black. Naturally, when people's eyes are placed, it is as if there are only these two dragons and phoenixes on the face of the dagger.
But if you ignore the black parts and only look at the white areas, you will find that the places you ignored and ignored are actually topographic maps. The only white belly on the dragon is no longer the abdomen, but also becomes a topographic map.
The three princes and Qing princes both followed what Li Chengze said to look again. This time, this time, they saw a little better.
"It turned out to be true, and Cheng is really talented! Blame Father Father must have you follow along."
Li Cheng said: "The three princes are utterly praised, and the Cao Min dare not be.
The three princes laughed and patted Li Chengze on the shoulder affectionately, "You are agile in thinking, wise, and you have done a great job. I will tell my father when I go back."
The fifth prince also admired Li Chengze very much, and nodded in agreement.
After a while, he couldn't help walking by Li Chengze's side and asked: "Why did you think that the map was not real in the first place? It was also related to the dragon and phoenix dagger. If the king remembered correctly, you must have been close. Have never seen dragons and phoenix daggers?"
Li Cheng pondered for a while before he said: "Guess, that piece of different shades on the original map is very similar to the handle of a dagger, what do you think of it? Naturally it is in the same place as it. Dragon and Phoenix Dagger."
The fifth prince was silent for a while, and said his heart, except for you, none of us expected.

To make up for the missing part of the parchment scroll, the third prince ordered the people to simply draw the topographic map on the parchment scroll as it is on paper, adding the part of the house from the dragon and phoenix dagger.
About half an hour later, they finished drawing the map without making a mistake.
Now that I think about it carefully, these things have always been one after another.
First of all, the two observances that the people of Yan country accidentally got were like lions and beasts. One was easy to open, with a dragon and phoenix dagger inside, and the other had a very complicated mechanism lock. It took the people of Yan country even five years to fail to open it. Only then did it have a chance to be sent to Daye.
Until I met Li Chengze, a proficient mathematics wizard.
After that, he took out the sheepskin scroll map and guided them to Yulianshan.
After entering the mountain, they found that it was wrong, the route was completely wrong, and there was no place at all.
If it were not for Li Chengze, perhaps they would never have guessed that this very difficult map was a fake.
Of course, it can't be said to be fake, but it's really hidden on the other side, and part of the dragon and phoenix dagger is missing.
No matter which one of them has a problem or cannot be solved, I am afraid that in the end, the location of the secret room on the map will not be found.
So speaking, the biggest credit here is Li Chengze.
Without him, they are afraid that sooner or later they will return without success.
The three princes really admire him. In fact, I have seen him before, and I also know that Li Cheng would write a novel, which was very popular in Beijing at that time, and now he is quite famous, although he has only written two books in total.
It would have caused trouble. At first, the three princes naturally pretended not to know Li Cheng. After all, Li Cheng married a lady from the Gu family and was the uncle of the Gu family. Now that the crown prince is standing, several adult princes are not staring at them, no matter whether you have that mind or not, it will be bad if you make the emperor doubt.
Shake off the complicated thoughts in the fun, hold the new map and set off again.
Walking back and forth in the deep mountains, turning around following the map.
For some reason, luck was surprisingly good, they hadn’t even seen a beast after they had been in for so long.
Perhaps it was because they were all sprinkled with exorcism. The exorcism was assigned by the emperor who accompanied them here, and Li Cheng thought that the emperor in the palace had some ability.
Occasionally a few small animals bumped into them, and before the guards raised their arrows, they ran away quickly by themselves.
The only animal that was fierce and bigger was a wild boar, which rushed out quickly, and was then solved by the guard with a continuous crossbow.
This time, I didn't find the wrong way. When I found the door of the cave, the time had passed.
The cave door is hidden behind a large hanging wisteria.
The entwined wisteria resembles a waterfall, spectacular and beautiful.
Everyone was stunned for a moment, but they didn't expect to be in this place.
Entering from behind the clusters of flower vines, the guard followed the instructions and scraped the mud wall with a big knife for half an hour, and all the stone wall doors inside were exposed.
Several people present were not excited.
Sure enough, there is another mechanism in the door, and it is still a math problem.
Everyone looked at Li Chengze.
Li Cheng expressionlessly picked up the charcoal pencil on the paper and counted silently.
To figure out the answer, I twisted a raised switch on the wall a few times.
With a "boom" sound, Shimen slowly opened...
The third prince gave an order to "enter."
The guards were in front and they were behind, and walked in together.
...
Gu Celadon waited anxiously at home and couldn't sit still. The two maids saw her in a bad mood, but they didn't know why.
While thinking that the lady likes to eat iced milk and iced cheese, she walked over and asked: "Madam, do you want to eat some ice, and the slave and maid will let the kitchen make a bowl?"
Usually Gu Celadon is greedy, but now she has no thoughts and doesn't want to eat it at all.
Fucked his eyebrows, shook his head and said, "No, my father-in-law wouldn't let me eat more ice. You don't need to wait on me here. You can go and take a look outside. Has the prince come back?"
Fortunately, Li Cheng didn't make Gu Celadon anxious all night, and the group finally came back as you approached the hour.
When Gu Qingci saw someone, he pulled him up and down to look up and down. Seeing that Li Cheng was fine, his heart fell back to his stomach, but he was still aggrieved: "It's dark, how can I return? I am worried to death."
Where can you stay in the mountains at night?
Li Cheng knew what she was afraid of, and squeezed her hand and said, "It's okay, it's okay. We came out before dark, and we didn't encounter any danger."
The two entered the inner room and talked. Gu Celadon asked softly: "What can I find?"
Li Cheng smiled, then nodded.
Gu Celadon was overjoyed, "That means we can go back soon, right?"
"Yes," Li Cheng sighed, "The next thing is that the three princes should be busy. As a husband, just accompany my officials, okay?"
