There is no reason to criticize the officials. Chen Fei also did not return the copper coin to the radish head.

returned to the bedroom, lined up the seventeen copper coins on the table one by one, and looked at them in a daze.

Lin Xi was very abnormal and did not wander around the garden, but sat on the bed in a daze, but she also noticed the difference, Chen Fei did not deliberately do anything to her this time, just sat on the table by herself, looking at the copper coin in a daze.

After being silent for a long time, Chen Fei said in a deep voice: "Do you know, these copper coins may be a child's income for half a year, but when the tax was levied today, seventeen were levied, and he only had four left." ”

Lin Xi listened in a daze, didn't dare to talk, and didn't dare to look at Chen Fei.

"I want to return these seventeen copper coins to him, but I can't! I gave it back to him, what about the other turnip heads? This is the foundation on which Datang still stands on this land. Chen Fei covered his face with his hands for a long time before letting go.

At dusk, the duplicate sand table had been brought, Chen Fei put the sand table on his table, put away his mood and looked at it seriously.

With this 3D map, Chen Fei has an intuitive understanding of the terrain of Hutou Pass, there is a narrow pass in the west, and the three gates of Hutou Pass stand here, and Hutou County and Hutou Pass are close to each other, two kilometers away from Hutou Pass, is the mine, there is a river next to the mine, zigzag, but it is generally a huge C-shape, directly extending to the bottom of the map - south. The huge plateau is also very obvious on this map, like two faults, all of which are lofty mountains, and Crescent Bay is also a small one on the map.

Chen Fei looked at the map carefully, arranged in the direction of north and south according to the standard, in this square map, Hutou Pass is at the top of the far left, the upper left corner is the mine, the Hutou River has a big "C", falling in the lower right corner of the map, and the long cliff is almost parallel to the lower edge of the map, what makes Chen Fei care is that the huge slope on the cliff is only about five kilometers away from Hutou County in a straight line.

Is it possible to create a road directly to connect to this slope?

Chen Fei's heart moved, and he began to try to plan a path in it, but he found a small red valley, colorful on the map, Chen Fei didn't care too much, but at this moment, he heard three words marked on it: Falling Dragon Valley.

The name...... Chen Fei was immediately startled, and hurriedly found Sun Qiao to ask, and immediately understood.

"This is the fifth-level Demonic Beast Fire Dragon King who was personally killed, at that time, this evil dragon almost destroyed the entire Tiger Head Pass, Chen Zu had better duel with this dragon here, and finally kill it," Sun Qiao said mysteriously, "The dragon bones of the evil dragon are still buried in the Falling Dragon Cave." ”

asked about the size of this dragon again, Chen Fei was even more shocked, according to what Sun Qiao said, this dragon is forty meters long! You must know that the largest blue whale on the earth is only 33 meters, and this is the limit, and the average blue whale can grow to 20 meters, which is already extremely remarkable.

When this thing is empty, you must take a look. Chen Fei secretly said in his heart, Lin Xi was still in a daze outside at the moment, and there was no one in the house, so Chen Fei quietly started Bole.

"Bole, the shortest route from the mine to the impact lake." Chen Fei said in his heart, the impact lake is the lake that the Tiger Leaping Gorge Waterfall knocked out, and the next moment he was speechless, Bole directly connected a straight line between the mine and the impact lake......

Lao Tzu flew over! Chen Fei was speechless, although this is indeed the shortest route.

So cautiously added: "Ground route." ”

Chen Fei was speechless again, viaducts, tunnels......

Just a little bit to supplement the conditions, after half an hour Bole finally calculated a most reasonable route, with a minimum amount of construction route, the most reasonable route directly from Hutou County through the Falling Dragon Valley straight into the landslide area, such a route is obviously the most reasonable, and in the big landslide down is to increase the volume, but this road in the mountains, although has deliberately avoided many places to open mountains and bridges, but the amount of construction is still very large, Hutou County's primary construction machinery only hoes, senior construction machinery is a pickaxeIt is too difficult to complete this construction volume in 40 days, plus mining and handling, it must be too late for 40 days, so Chen Fei chose the second method: river transportation.

The mine is on the Hutou River, Chen Fei's plan is to go down the river, stop the boat when he reaches the Hutou Gorge - that is, the turbulent area, and open a mountain road to the bottom of the big cliff, where is the gentle area of the river, although the river is too shallow, but Chen Fei can try to make a flat-bottomed boat, even if he can't build it, he will make hundreds of bamboo rows in a hurry, how to say that these iron ores will be transported to Zhuzhou!

Now that the route drawn by Bole has come out, of course, Chen Fei and Bole do not have specific data, such as soil quality, roadbed, etc., but this road is already the most reasonable plan at present.

Now there are only 39 days left before the grain is delivered, Chen Fei does not dare to be idle, and immediately begins to carve the route projected by Bole in his eyes, this map is made of dough, but it is easy to sharpen, but if it is cut too much, it is not easy to make up for it, it is because Chen Fei is cautious and does not dare to slack off.

This is not an easy task, a mountain is only half the size of an egg, how easy is it to carve a path on it?

It's like looking at a word the size of a sesame seed, just two hours, Chen Fei's eyes are already sour, but Chen Fei is holding on, knowing that there is the slightest deviation here, and the actual construction is the amount of construction for most of the day, so he is cautious, until midnight, his eyes are really swollen and painful, and then he came outside the house to look at the night sky and relax.

It's just this starry sky...... It's not even as good as the starry sky of Daliang Mountain. Tang Wang once said that the planet of the interstellar zoo is a huge planet that deviates from the main star area, and it seems to be true at this moment, the stars in the sky are extremely sparse, and occasionally see one or two, which is also small and pitiful.

"Your Highness, the slave maid will make you a supper, what do you want to eat?" A servant girl saluted, Chen Fei was startled, and said, "Uh...... You give me a kettle of hot water, I'll put a compress on my eyes. ”

"Yes, Your Highness."

The servant girl retreated, and Chen Fei also sighed secretly in his heart, there is no easy person in this era, his own light movement, this servant girl immediately woke up, and it is not easy to be an ordinary person.

Waiting until the maid brought hot water, Chen Fei simply asked her to massage her eyes with a hot compress, the maid looked at the sand table and was obviously very curious, but she didn't dare to ask under the huge gap in identity, just peeked at it from time to time, Chen Fei smiled secretly and explained it simply, the maid was naturally amazed again, and finally it was over, Chen Fei carved it again.

It wasn't until dawn that Chen Fei finally completed the carving of this road, and directly knocked on Sun Qiao's door carefully.

Sun Qiao scolded and opened the door, and when he saw Chen Fei, he was stunned for a moment, and even said to ask Chen Fei to forgive his sins, Chen Fei scolded a few words of old **, and directly put the sand table on the table.

Sun Qiao immediately understood when he saw it, "Mingfu, you...... Or do you want to go by water? After looking at it for a while, he immediately exclaimed: "Wonderful! Wonderful! Mingfu is really Crouching Tiger, Hidden Dragon among the people you bring, this route is extraordinary! Extraordinary! ”

……

Chen Fei wants to say that Lao Tzu carved it for a long time, you dead old man, gave the credit to others with a word? But after thinking about it, it's okay, it's nothing to be in the limelight, but this ability can't come out overnight, I'm afraid that some people will doubt it when you look into it, and pinched your nose and said vaguely: "Well, my subordinates got it." ”

"Ming Mansion, please be sure to introduce me, for this person, I really admire it from the bottom of my heart!"
