Yang Ji continued to look down, and there were a lot of scattered clues like this. ∈↗Not every place was recorded in such detail. As long as there was a Nongsang Guku, he had collected them. .
Moreover, Yang Ji discovered that the pages inserted by Chen Sicheng in the library were very miscellaneous, and not all of them were from Nongsangsi. Some of them were completely unrelated to Nongsangsi. Just because they appeared in them. Narrative about the previous dynasty.
"He is collecting information about the previous dynasty."
Yang Ji flipped through several pages and found information about the previous dynasty. Some of the information was very new and was clearly collected by Chen Lao Sicheng from outside.
These materials from the previous dynasties were very scattered. Looking at them individually, Yang Ji really couldn't judge the basis for such collection. Until he saw an object the size of a child's palm in the book page. It was withered and incomplete, and some places were still blurry.
"Map of the previous dynasty!"
Yang Ji stretched out two fingers and picked up the piece of paper from the pages of the book. Facing the light of the oil lamp, it was clearly an incomplete map of the former dynasty, with densely packed winding curves on it.
In the center of the map, the word "Langya" is clearly visible. It's just different from what Yang Ji knew. The map of Langya shown on this piece of paper is very different from what Yang Ji knew.
——This is a map of the previous dynasty more than a thousand years ago!
In the flash of lightning, Yang Ji looked at the incomplete map of the previous dynasty in his hand, and countless thoughts flashed through his mind. The rise of dragons and snakes, changes in the sea, more than a thousand years of time, crustal movements, and tragic wars can all lead to changes in the surface terrain. .
There is no doubt that the current mountain topography of Langya County has changed greatly from that of the previous dynasty more than a thousand years ago. It is undoubtedly difficult to see the current terrain from the maps of the previous dynasty.
But seeing this, Yang Ji already understood what Chen Lao Sicheng wanted to do.
"...He wanted to find the Nongsang Ancient Library through the map of the previous dynasty, and then determine its location by comparing it with the modern map."
A thought flashed through Yang Ji's mind, and he finally fully understood Chen Lao Sicheng's thinking. In more than a thousand years, the characters, cities, and terrain will have changed greatly.
However, everything remains unchanged. No matter how it changes over the past thousand years, there are always some things that will not change. As long as you find those things that remain unchanged, you can roughly determine the positions on the two maps. Then find out The location of Nongsang Ancient Cave.
"...No wonder Chen Lao Sicheng spent so much energy on drawing the Langya map."
Yang Ji suddenly understood. He had completely understood Chen Laosicheng's plan. If he wanted to determine the Nongsang Ancient Library by comparing the two maps, he must first have a map of Langya County.
Chen Laosicheng must have wanted to draw a complete map of Langya, then compare the two maps to find similarities, and then carry out the final positioning work.
"It's a pity that the year never ends. Chen Lao Sicheng spent so much energy, but in the end he couldn't complete it."
Yang Ji sighed in his heart and couldn't help but secretly regret it.
He had actually completed more than 90% of this work. Unfortunately, even when he died, he still was not able to draw a complete map of Langya.
Yang Ji secretly regretted that this work could only be completed by him now.
Looking back all the way, Yang Ji saw many incomplete maps that Chen Lao Sicheng had collected from who knows where. These things were only part of them and not complete.
But looking at these incomplete maps of the previous dynasty, Yang Ji had slowly pieced together a complete map of the previous dynasty in his mind. Turning to the last page of the book, in the cover, Yang Ji found a map drawn by Lao Sicheng.
A map.
He folded the map into a square shape, and after opening it, it was almost exactly the same as the map that Yang Ji put together in his mind. There was an eye-catching black spot on the upper left side of the map, which was the location of Nongsang Ancient Cave.
"Master Chen, don't worry. No matter what, I will fulfill your last wish."
Yang Ji sighed deeply, pulled out the map inside, closed the book, and inserted it back into its original position on the bookshelf.
Leaving the room and passing through the alley where he came from, Yang Ji returned to the lobby of Nongsangsi Yamen. He leaned down and collected the drawings on the ground one by one, flattened them carefully, and arranged them.
Then put it on the desk.
Chen Lao Sicheng's work has been completed 90%. Now there is only the last and most critical step left!
Yang Ji took out a Nongsangsi writing brush, spread out a piece of paper, dipped it in ink, pondered for a moment, and then drew the Langya map in his mind, which was made up of hundreds of drawings.
Integrating hundreds of complicated draft drawings into a complete map is undoubtedly a huge task that requires a lot of effort and time for an ordinary person like Chen Lao Sicheng.
But for a warrior like Yang Ji, it is far less difficult than imagined.
The lights flickered, and Yang Ji wrote alone in the firelight. It was not difficult to put these draft drawings together, but it was necessary to simplify this huge "Langya Map" into a map of the same format according to the abbreviation method of the previous maps.
But it's not easy.
Chen Lao Sicheng's map is too detailed. But the real map is far from that detailed - at least the maps of the previous dynasties collected by Chen Lao Sicheng are far from so detailed. Yang Ji needs to trim these detailed terrains, and
Minimize it to a certain scale to create a standard map similar to the previous map.
"No! There are at least five or six places in this map that are not perfect, so there is no way to create the map you want."
Half an hour later, Yang Ji stopped his brush, his eyebrows deeply furrowed, and he looked at the brush. There were still some things that Old Sicheng could not draw.
Yang Ji originally thought it would not have much impact, but at the last step, Yang Ji discovered that without these parts, this map could not be produced at all.
"We can only stop for a moment. We have to fully paint the remaining places before we can describe it."
Yang Ji sighed and put the brush aside. Fortunately, there weren't many places that Old Sicheng couldn't draw. With Yang Ji's ability as a warrior, it wouldn't take long for him to finish it.
The next day, at dawn, Yang Ji rushed to the northwest. In the next few days, Yang Ji was busy running around. There were cliffs everywhere, and abysses and chasms everywhere... Yang Ji took a pen and paper and went to a place.
Draw a picture everywhere.
Five days later, Yang Ji returned a stack of manuscript papers to Ganongsangsi Yamen.
"Finally finished!"
Yang Ji hung the pen on the pen holder, looked at a small map of Langya with still wet ink in front of him, smiled and let out a long breath, as if a heavy burden had been lifted.
No matter what, I finally completed the last step of Lao Sicheng's last wish! The map in front of me was only the size of a palm, and compared with the hundreds of drawings, it was far less detailed, but this was exactly what I needed.
Yang Ji's left palm held the Langya map he had drawn, and his right palm held the Langya map of the previous dynasty that Lao Sicheng had summarized from those ancient books and maps. He compared the left and right, his eyes wandering.
Whether you can find Nongsang Guku depends on these last two pictures.
Yang Ji looked solemn and looked at the two maps without moving. From the content point of view, the topography of the two maps was completely different.
If they didn't know better, many people might think that these might be two completely unrelated maps at first glance. However, Yang Ji carefully distinguished and found some similarities between these two seemingly completely different maps.
"Ten Thousand Tombs Ridge..."
Yang Ji's eyes were sharp, and he suddenly stretched out a finger and clicked on a point on the map among the messy and twisted lines, "This location is Wanfenling."
The origin of Wanfenling is ancient, and it has been a battlefield in the past dynasties. Whether it is the previous dynasty or the current dynasty, the location of Wanfenling, a mass graveyard, has never changed.
No matter how the two maps change, the location of Ten Thousand Tombs Ridge will never change. In thousands of years, if the land changes, this place will still be here.
The first point is confirmed!
Yang Ji breathed a sigh of relief. In the beginning, Wanfenling was an unexpected gain. As long as you find the first point, there will be a second unchanging point and a third unchanging point...
As long as three different points were determined on the two maps, Yang Ji could basically find the location of the Nongsang Ancient Cave of the previous dynasty on the Langya map of the Han Dynasty.
"Langya City can no longer be used as a basis for positioning, and the official road cannot be used. The previous dynasty was completely different from now. The current city might have been a wasteland before."
Yang Ji secretly thought in his heart. The outstretched index finger kept wandering among the twisted and complicated lines. In Yang Ji's eyes, these twisted lines were like a constantly changing mountain and stream.
Langya County is close to the sea, and the constant collision and squeezing between the sea and the land will cause earthquakes. In Langya County, earthquakes are not too frequent, but there will always be one every few decades.
Therefore, more than ten years ago, when Pingchuan City suffered a disaster from the underworld, the imperial court covered up the truth and said it was an earthquake. No one suspected that this was the reason.
These earthquakes have long been recorded in the Langya County Chronicles.
Yang Ji had come across records in this area when he was reading books before. Earthquakes were precisely the cause of the changes in the sea and the land.
More than a thousand years have been enough for the terrain of Langya County to undergo great changes. This has caused great trouble to latecomers like Yang Ji.
Yang Ji frowned and said nothing. Among these complex and twisted lines, he kept trying to identify things that could be connected.
"Mountains, rivers, these are completely useless as a basis for identification..."
Yang Ji frowned tightly. It was not easy to identify three constant points on two different maps.
Yang Ji thought hard, looking at the two small maps in front of him with concentration, motionless.
"Pingchuan City..."
An idea flashed in Yang Ji's mind, and he suddenly remembered Pingchuan City, "Although Pingchuan City may not have existed during the previous dynasty, there is a huge space-time vortex outside Pingchuan City that runs through the underworld." (To be continued, please search Piaotian Literature.
