The Golden County Magistrate

Chen Yan did not answer him directly. He took out a fountain pen from his bosom and started drawing between the two points he pointed to.

Before everyone could be amazed by the unprecedented pen, their attention was attracted by the line he drew.

In a blink of an eye, a series of winding lines were drawn on the topographic map, and finally connected the two points together.

"It is the most correct way to construct along this line!" He said heavily.

Everyone was stunned.

Even Xueyan was the same. She was surprised and said, "Master Chen, did you draw it wrong? If you draw it like this, won't it make the line longer?"

In the original architectural book, the line that Jin Ze and others thought of was basically a straight line.

Therefore, when they looked at the two points pointed by Chen Yan before, they also imagined it as a straight line.

But unexpectedly, the line he drew was not only not a straight line, but also went around in many places, and even went around in two circles in a few places!

The distance on the straight line was about one foot, but now it has become at least three feet!

Jin Ze sneered again and was about to speak.

"Shut up and listen to me!" Chen Yan said coldly. Without waiting for Jin Ze to get angry, he moved his finger on the topographic map: "From here to here, and here, and here..."

He pointed to dozens of locations in one breath, and then said: "These places are natural canyons, and the terrain is lower than the Fairy River. Although it is a long detour, it is not necessary to break through the mountains. As long as the blockage is broken through at the junction between the canyons, the canyons can be used as a road to lead the Fairy River water to the east into Jizhou!"

The cabin was instantly quiet.

Everyone stared at the places he pointed at. After a while, Jin Ze turned to Zeng Hong and said, "Are these places really canyons?"

Zeng Hong said in panic, "This, it is indeed not visible from the map."

A person next to him quickly took out the map he brought, put it on the table, and unfolded it to look at it carefully.

In fact, they didn't know how many times they had looked at this map. Even if they looked at it again at this moment, the result would be the same.

The map of the Great Zhou was limited by the limitations of human exploration. In places like Tianxuan Mountain, where there are deep mountains and old forests, even horses cannot walk, and people can only walk and climb to explore, which is extremely time-consuming and laborious.

It takes time and energy, but some places are directly cliffs and gullies, and it is impossible to even go through them. The surveyors can only climb high and look far, and rely on their eyesight to determine the terrain. They can see some peaks in the deep mountains, but can't observe canyons at all.

Therefore, the maps drawn do not have those at all.

"Hmph, you can't even see it on the map, and you want me to believe your nonsense?" Jin Ze snorted coldly.

Without saying a word, Chen Yan grabbed the map and tore it into pieces.

Everyone was shocked before they could stop him: "You are crazy! This map is so important, how dare you..."

Before he finished speaking, Chen Yan had taken out a brand new map from his arms, unfolded it into a three-foot square, and placed it on the table.

"This is..." Jin Ze said in surprise.

"Those useless things have been torn up long ago. Take a good look. This is the complete map of Tianxuan Mountain!" Chen Yan said coldly.

Everyone had no time to pay attention to his words because their attention was all attracted by the map.

Even Xueyan was no exception. She came closer and took a closer look. The more she looked, the more shocked she was.

There was such a detailed map in the world, which simply overturned her understanding of maps!

This map was prepared by Chen Yan before he came. It has been improved compared to the one he gave to Tang Yun last time, such as the scale and details. However, this map does not include the entire Great Zhou territory. It is a partial enlargement, only including the Tianxuan Mountains and its surrounding hundreds of miles.

But because it is enlarged, it can show more details, from grasslands to forests, from mountains to rivers, and even places where people live are marked.

And most importantly - all rivers, canyons, peaks, etc. are marked, including some places that used to be rivers but are now dry and covered by sand and mud.

It is even painted, with different objects using different colors, so although it is much more complicated than ordinary maps, it is still clear and easy to understand.

From this map, you can clearly see that the places Chen Yan mentioned are indeed canyons!

"Impossible... How can there be such a detailed map..." Jin Ze murmured, his fingers trembling as he slowly slid across the map, and he couldn't believe it.

The expressions of the others were not much better. They were all veterans who had studied water affairs for decades. How could they not be surprised when they suddenly saw this magical thing that was beyond common sense?

Chen Yan took in everyone's reactions and sneered slightly.

This picture was already a dimensionality reduction attack.

Long before he suggested to Tang Yun that he use gunpowder to blow through the barrier of Tianxuan Mountain,He had studied the topography of all places in Da Zhou in depth.

Of course, the original purpose was not disaster relief, but to find mineral deposits.

Later, after Tang Yun agreed to spend a huge amount of money to buy gunpowder, he carefully studied the topography of the Fairy River and Tianxuan Mountain again, and re-drew this enhanced map with the help of the topographic data that had been explored in recent years with huge manpower and material resources.

Tianxuan Mountain was obviously formed by the rise of the valley caused by crustal movement, which formed the current continuous mountain terrain. Therefore, there are hundreds of river-type canyons between the peaks in the mountains.

He also repeatedly studied which routes to take many times, and finally chose the current route.

After a long time, Zeng Hong raised his head and said suspiciously: "Is this map really reliable?"

Chen Yan's eyes were as cold as a blade: "If Lord Zeng doesn't believe it, you can send people to explore and see if it is as I said!"

Xue Yan, who was next to him, was seeing him so cold for the first time. There was an unprecedented sharp and majestic look, which made her heart tremble.

Oh my God!

This county magistrate, who was usually laughing and joking, not serious, and greedy for money, actually had such a terrifying side!

"Humph, it's easy to say, how can this be surveyed clearly in a few words?" A person next to him muttered.

"If it can't be surveyed clearly, that's your problem, not mine." Chen Yan said bluntly.

"You!" The man was speechless for a while.

"Okay! This map will be left here, and I will make a conclusion after studying it. County Magistrate Chen, you go back and rest." Jin Ze ordered him to leave.

Chen Yan had been eager to leave, and returned to his normal state: "Then I will take my leave for now."

Xue Yan followed him out of the cabin. After Zeng Hong closed the cabin door, he frowned and said: "Sir, should we trust this man?"

Jin Ze let out a long sigh and said: "It is impossible not to trust him now. The emperor is concerned about this matter and requires us to work together. Since he has this map, we will trust him for now. If we arrive at the place and find that the terrain does not match the map, then the responsibility will be on him, not us, understand?"
