This method is summed up in one sentence.

The cliff is too high? That's simple, just fill it up!

The 50-meter-high cliff is a completely unaware of the natural barrier for most ordinary people on the Continent of Sainz. So when he first heard that Xu Yi wanted to build a road to the Kingdom of Ruhrson from here, he thought he was crazy at all.

But for Xu Yi, on a technologically developed earth, a 50-meter-high cliff is not a difficult difficulty at all.

On Earth, there are many ways to solve this problem, but limited to the current technological level on the Synes continent, Xu Yi finally chose the simplest and most crude method, which is to fill the cliff.

Specifically, it is to use a large amount of stone and earth to increase the lower Duchy of Stantin to form a roadbed that is sufficient to connect the other side of the cliff.

It is of course impossible to say that it is completely filled. What Xu Yi asked was to fill out an uphill roadbed that could be used to pave the road.

Considering the height of the cliff and the slope of the road, according to the calculation, the length of this roadbed will be as long as five kilometers. With the roadbed of at least fifty meters wide, the required stone and earthwork will be astronomical.

If we were to use the previous technological level on the Synes continent, whether it was excavation or transportation of stones and earthworks, we could only use manpower. To complete such a huge project, at least tens of thousands of migrant workers would have to be used, and it took several years or even more than ten years to complete it.

Such engineering quantities have no other possibilities except for the reflection of the national will.

Now, with the help of the engineering magic machinery developed by the Xinfei Chamber of Commerce, this project seems much simpler.

After careful exploration and data calculation by the Amley Chamber of Commerce, it was finally estimated that as long as the New Air Chamber of Commerce can provide enough large and medium-sized magic excavators and large magic load-load locomotives, the huge project will require no more than three thousand manpower and will not take more than two years.

If everything goes well, the entire Slu Road will most likely be completed within five years.

However, although the manpower and engineering time are greatly reduced, the investment will not be reduced too much.

According to estimates, the Slu Road will definitely be the most expensive road built by the Amley Chamber of Commerce so far.

Among them, the total length of this section of the road from Xu Yi's private territory to the border between the two countries is more than 140 kilometers. It is estimated that 300,000 gold coins will be invested.

The total length of the Ruhrson Kingdom from the border to Kuraka City is more than 560 kilometers, and it is expected to invest 1.1 million gold coins.

Both sections of highways are paved according to ordinary highway construction standards, and the estimated cost is also according to this standard.

However, from filling the roadbed to finally climbing to the top of the cliff, the total length of the section entering the Rulson Kingdom is only about five kilometers, and the estimated cost may exceed an astonishing 800,000 gold coins.

Together, the total investment of this Slu Highway is 700 kilometers, but the total investment is more than 2 million gold coins, and it may even reach 2.5 million gold coins.

Although the section of the road in the Rulson Kingdom will be invested by the Rulson Kingdom, President Cruise still feels that the cost of this road is too high. Some are not very cost-effective.

In his opinion, instead of spending such a high cost to build such a highway, the Xinfei Chamber of Commerce might as well just go around a circle, at most it only takes one more day and a small amount of freight, which is much more costly than building this road.

However, Xu Yi didn't have much of a sense of the price.

On earth, the construction of a highway is carried out at a cost of tens of millions or even hundreds of millions of yuan per kilometer. On average, the cost of a highway per kilometer is even less than 10,000 gold coins, which is undoubtedly much cheaper.

Although the artificial materials from the Sainz continent are extremely cheap, and the quality of the roads built is far from comparable to the expressways on the earth, the price still makes Xu Yi feel completely acceptable.

The reason why I insisted on investing a lot of money and overcoming such difficulties was actually because Xu Yi did not want to use the method mentioned by President Cruise.

It is certainly feasible to take a detour to transport goods to the Kingdom of Rulson, but if you want to take a detour, you must pass through the territory of the Kingdom of Lampari.

Not to mention that you must pay certain tariffs when entering and leaving the country in the Kingdom of Lampari. If the Kingdom of Lampari is prohibited from passing by, it will be too late for the New Aircraft Chamber of Commerce to seek solutions.

After all, the Xinfei Chamber of Commerce is currently actively developing large magic ships suitable for deep-sea and ocean navigation, and the construction of this Slu Highway, in order to transport the cargo produced by the Xinfei Chamber of Commerce to other parts of the continent more conveniently and quickly.

Although the Principality of Stantin is pleasant in the climate, very suitable for living, and can not be disturbed too much, the terrain here is really limited. If you don’t find a way to solve this problem in advance, the New Aircraft Chamber of Commerce will only have a dead end.

Of course, these issues are not within the considerations of Elder Lisanya. She came to meet Xu Yi this time mainly because the Slu Highway subgrade leveling project happened to pass through the Yueying Forest where the Yueying tribe is located.

To fill the ground and improve the roadbed, of course, it will affect the terrain of the Yueying Forest on a large scale, so Xu Yi must obtain support from the Yueying Tribe in advance.

Before, Xu Yi proposed this project construction to Elder Lisanya and asked for cooperation, he obtained preliminary approval from Elder Lisanya.

This time Elder Lisanya came, and did not show any strange expression. Xu Yi naturally thought she had decided to cooperate.

Sure enough, after hearing Xu Yi's question, Elder Lisanya nodded and said, "Well, there is no problem with cooperation. After all, if you can directly access the Rursun Kingdom, it will also be beneficial to our tribe."

Xu Yi smiled slightly and waited for the following text.

Elder Lisanya paused and said, "But... President Xu, I must make a few requests."

"Speaking."

"First of all, building this highway will cause a lot of damage to the Yueying Forest. Therefore, it will have a certain impact on the lives of our tribe. President Xu. You should give some compensation to our tribe."

Xu Yi couldn't help but smile.

Who said that the elves are so proud that they are disdainful of being as petty as humans? At present, Elder Lisanya is just bargaining with him.

"This is of course. I just don't know how much gold coins do you think we will be satisfied with?" Xu Yi asked with a smile.

"No. Simple gold coins don't mean much to us, and we are not very short of them now." Elder Risanya shook his head. "Oh? Then what compensation do you need?" Xu Yi was slightly surprised.

"We need some practical help. For example, because there is not enough water source in the Yueying Forest, it is always very difficult for our tribe to use water. President Xu, I heard from Erxia that your first contact with their Yege tribe was to help them solve the water source problem. So can you help our tribe solve this problem as well?"

Xu Yi pondered for a moment and nodded: "Although this requires field investigation to know the exact answer, it should not be a problem. For example, with the ability of the siege machinery developed by our Chamber of Commerce, we can mine a large amount of groundwater from Yueying Forest for use for you. I can even create a comprehensive automatic water supply system for your tribe to ensure that each of you tribe can use a clean water source without leaving your home."

"Really?" Elder Lisanya's face showed surprise. "There is such a convenient system? That's great! President Xu, I'll order such a system from you now. It's okay to ask me to pay additionally."

Xu was also puzzled when he saw Elder Lisanya's excitement in his application.

Is every elves tribe facing the water source problem?

Whether it is the Yege Tribe or the Yueying Tribe, the first problem he asked him to help solve is actually this problem.

Regarding this comprehensive automatic water supply system, Xu Yi has actually started a small-scale fact on his own private territory.

For example, a magic water pump is placed underground in his manor, which is continuously pumping groundwater into a newly built water tower in the manor, and then flows into various pipes through the water tower for use in all rooms needed.

This automatic water supply system has been developed less than two months ago and is still in the test stage. After the test is confirmed to be feasible, it will be promoted to the entire territory.

Xu Yi’s goal is to allow every household in the territory to use clean tap water in the first half of next year.

"What about other water sources? Are there any requirements?"

"Apart from the water source problem, there is nothing important."

Elder Lisanya smiled and made several more requests. It turned out that none of them were too important. He just hoped that the Xinfei Chamber of Commerce could provide more convenience to the Yueying Tribe.

For example, Elder Lisanya hopes that the Xinfei Chamber of Commerce will develop newer fertilizer processing machinery for the Yueying tribe's fertilizer processing plant to improve the efficiency and output of the fertilizer processing plant.

For example, the Yueying tribe hopes to build a small elf town outside the Yueying Forest, imitating human towns, and hopes that Xu Yi can negotiate with Grand Duke Stantin and Lord Viron to obtain their approval.

For example, Elder Lisanya hopes that the Xinfei Chamber of Commerce will tailor a special magic sedan for her according to her requirements...

...

After hearing Elder Lisanya's request, Xu Yi's gaze at her changed drastically.

Compared to ordinary elves, this elder Lisanya is more like a shrewd human businessman and has absolutely not given up any of his own interests because of the so-called pride and reserve of the elves.

During the previous process of cooperating with the Yueying tribe, Xu Yi did not have a deep understanding of this, but this time he had a deep understanding.

Because Xu Yi was basically satisfied with all the requirements he made, Elder Lisanya seemed extremely satisfied. After finalizing these compensations, she smiled and nodded.

"Very good, President Xu is indeed the best friend of our elves. As a noble elves, I must respond enough to your generosity. President Xu, in fact, I can provide a brand new solution for this roadbed heightening project, which can save you at least 500,000 gold coins and a lot of time. Are you interested in this?"

Xu Yi was stunned.

No way? What kind of solution can save a full 500,000 gold coins at once? Can it save a lot of time?

This is simply a fantasy!

However, thinking of the usual mystery of the elves, Xu Yi's face immediately became cautious, sat up straight, and stared at Elder Lisanya.

"I would like to hear the details." (To be continued, please search Piaotianwen, novels are better, updated and faster!
