As soon as these words were said, half of the Han court officials had broken the string called reason, but looking at the terrain, they had to accept this fact. When they were young, they all went to the battlefield and knew that the mountain road was difficult to walk, so this time was very reasonable.

"Tell me a different plan, the road construction plan." Zhang Jian couldn't help it and directly relied on his seniority. My life was not for you guys who were squandered. I've lived a few years ago. Let me see if that place is OK before I die, and give me a correct word.

Sun Gan nodded. There will be many old guys from previous generations, senior generations, and even senior generations in this dynasty. These are all old guys who don’t like you, Cao Cao, and Cao Cao can’t do anything good to them, but the respect you should have to be given.

"This is the second solution!" The light curtain changed instantly, and a viaduct appeared on it, connecting directly from this hill to another hill. It might have taken several days to turn over the distance, and it was done directly within a few minutes.

"This is a bridge..." Zhang Jian said with his eyes narrowed, and then he instantly understood the reliability of this plan. He couldn't help but admire Sun Gan. "This method is very good. It is a smooth road from Chengdu to Central and Southern to use this method."

"Well, it's really a smooth road." Sun Gan nodded and said, spending a lot of effort, leading a bunch of masters, and a mathematician for eight months, finally confirmed the design, and now he can finally start construction.

"This plan..." Liu Tong looked at it for a long time and finally spoke, "How much is the value?"

"Your Majesty, please don't ask." Zhao Qi said with a wry smile, "What if the cost of construction exceeds 100 million yuan? Even if the construction cost is less than 100 billion yuan, will everyone here give up the construction? Asking will only make people worry."

As soon as Zhao Qi said this, let alone Liu Tong extinguished the inquiry idea, all the court officials lost interest in asking about this matter. As the old lady often said, what is the use of asking? Can you not repair it after asking? Definitely not. No matter how much the cost is, as long as the Han Dynasty can take out such a thing, everyone in the Han court will definitely repair this road.

Just focus on the land that was ripe for Kushan that year and the fertile soil with a yield of more than ten stones acres, no matter how high the cost is, the Han Dynasty officials would not stop. Since this is the case, don’t ask, and it will save you trouble.

"In short, the county road from Chang'an to Hanzhong, and Hanzhong to Chengdu will be repaired soon. Since it is a straight line of road construction, a regular cavalry legion with one man and two horses can be guaranteed to arrive within eight days from Chang'an to the level." Sun Gan explained with a smile.

The road from Chang'an to Chengdu basically completely solved the problem of Sichuan and Sichuan rebellion.

In fact, the distance from Chang'an to Chengdu is not very far, only more than 600 kilometers. In the past, it took several months to leave Sichuan. If it was slow, it would even last for half a year. In fact, it was more caused by roads. Liu Zhang and Cao Cao's road construction methods were directly straight.

The distance of 600 kilometers, with the marching speed of ordinary cavalry legions, actually arrived in eight days. After all, the rise of the essence of heaven and earth has indeed strengthened a lot of things.

As soon as Sun Gan said this, it was like giving everyone a heart-wrenching injection, even the old guy's breathing was a little heavier. This was the rhythm of going to heaven. From Chang'an to Chengdu, one man and two horses, and the army was dispatched, it only took eight days to arrive.

Compared with the distance between Chengdu and Central and Southern China, the difference is actually only two or three times from the map. Doesn’t this mean that if this road is repaired, it will take only one month to forty days to send troops from Chang'an to get there? This can be directly used as the local essence area!

In terms of the current ruling ability of the Han Dynasty, the march mileage within fifty days is not a matter of interest. The rule limit of the standard empire is almost about one hundred days. Since the road construction can greatly increase the limit range, what's there to say? If you don't repair it, you won't be a human being!

What's more, since the road construction can include that place in the Han ruling area, there is nothing to say. It must be built, and you can go directly through one road and declare that you are all ours!

"Since that's the case, we should start construction now." Zhang Zhao asked suspiciously.

"The construction period will take about fifteen to twenty months, and we will start construction in several places at the same time." Sun Gan nodded and said, and suddenly several old men from the court, who were taken out and sent to the Imperial Medical Office. Their hearts could not withstand this impact.

"Can you hurry up or not." Zhao Qi seemed to be the kind of guy who was particularly slutty. He did not feel heart discomfort due to this impact, and he could still ask excitedly.

But no matter what, he is a person in his nineties. Even if he is a very, very obsessive type, it does not mean that he is confident that he can live to a hundred years old. He has been buried in the neck by the loess. Even if Zhao Qi can eat and drink, he is worried about when his family will be finished.

If I hadn't had any worries before, I felt that it was over, but this guy really didn't want to be over recently. I feel that I have seen more lively in the past two years than in the previous three dynasties. I am the Emperor of the Governor and the Empress, and there will be such a great fun in the future.

With so much fun and not watching the finale, Zhao Qi felt that it would be a bit unfair to die now. The fertile soil that is three-ripe a year can produce twelve stones. Zhao Qi decided that he must survive until that day and then go and see. Now that he cannot die, Zhao Qi suddenly felt urgent.

"This really doesn't work." Sun Gan said helplessly, "This is the fastest speed. No matter how fast I can't guarantee the quality."

"Well, why don't I find some bridges for you. I think this is also a bridge." Zhao Qi said helplessly. I can't survive that time, but I can shorten the construction period. Isn't it just a bridge repair? Is there anyone who can build a bridge of this specification?

"This is OK." Sun Gan nodded and said.

Although Sun Gan nodded in agreement, he did not take it seriously. The bridge he wanted to build and the bridge that Zhao Qi knew were completely different. From Sun Gan's current perspective, basically, the bridge-building workers in this era need to be rebuilt.

"Do you think it's useless?" How could you not see Sun Gan's contempt in his heart if you're a young guy like Zhao Qi, "I see that this mountain is only four or five hundred steps away, and there are still some old guys who can repair this kind of bridge."

"Let me find you the people who built the Three Bridges of Weishui for you." Zhao Qi touched his chin and said.

Zhao Qi worked in Taichang for a long time, and the three bridges of Weishui often involved rituals and music, so Zhao Qi also repaired them. By the way, the three bridges of Weishui are one of the most famous bridges in ancient China. They were built during the Qin and Han dynasties, and the piers of Dongwei Bridge were still in use in the 21st century...

The so-called learning of civil and military skills and selling with the imperial family. In ancient feudal era, even if the major families had some secrets, they would have thought too much about comparing with the royal family that owned the world. The strongest group of bridge-building people in the world were basically squatting in the Han Dynasty Shaofu.

It can be said that in the situation of the Han Dynasty, if it were not for serious crimes, all kinds of characters would definitely be found as long as they were needed.

The bridge-making technology of the Qin and Han dynasties was forcibly lifted to a certain limit because of some freak-level bosses. The Zhongwei Bridge was used from the Qin Dynasty to the end of the Tang Dynasty and was finally destroyed by war. The bridge spanned nearly 900 meters from north to south...

Zhao Qi had never thought about building bridges between mountains before, but Sun Gan opened up and took a picture. Zhao Qi's mind turned around and then realized it.

Isn’t it just a bridge? A bridge on the water is a bridge, and a bridge on the road is also a bridge?

How far can the distance between the two hills? The Weishui Bridge spans nine hundred meters. How far can the two hills in the Hengduan Mountains be so far? Well, even if it can be so far, we can still build it longer. I have a fellow villager who has been doing this for seventy years. Twenty years ago, I heard that it was about to die. Recently, it seems that he was about to die. I think he could do it!

"Yes, the three bridges in Weishui are all about 500 steps. We still have bridge-building techniques of this specification, and we should be able to make two or three hundred people who can build such bridges." Zhang Jian also reacted now.

Zhang Jian was shocked before, but he didn't think deeply. Now that he has reacted, he suddenly realized that this is just a five hundred-step long bridge? I really thought it was difficult to build, and I have studied it for eight months. The old man's life is not for you to consume like this. I will give you a group of people and build it quickly.

We who are almost in the coffin are still waiting to see what the fertile soil with a yield of twelve stones per mu is, and we are still waiting for you to bring some back so that I can fill the grave before I die.

In fact, after Zhang Jian said this, the guys from the previous generation, including Jia Xu, had already reacted. Isn’t this a bridge with a relatively large span? No one else in the Central Plains can repair it, but there are actually hundreds of people in Chang'an that can repair it.

I walked the three bridges of the Wei River all day long, and I got used to it. I forgot that these three bridges are the embodiment of the highest-level bridge-making technology today. As expected, it should be said that it is a blind eye to Mount Tai. Habit is indeed a very terrible force.

"Yes, there are indeed about 300 craftsmen who can build such a long bridge with a span of more than 500 steps in Chang'an. They should work in the Shaofu now." Jia Xu said, pressing his temple, his eyes half closed, and the Weishui Bridge looked too familiar, so even he forgot that there was something else.

Soon Liu Tong called the Young Master to inquire about this matter, but the Young Master to the Young Master looked pale, "I am guilty of one hundred and twenty bridge workers and twenty-four professional bridge craftsmen, and now there are only less than a hundred people left."
