Before the installation of the familiar star tires, the horse-drawn carriage had an average speed of only 13 miles per hour on this road, but now the speed of the car has almost doubled, and the tires are a big credit, but they can't be fully attributed to the tires.

Since returning to Krasbourg from the Silver Sky ten days ago, Roland has gathered Matvey, Kafta and Molozov to form a "Carriage Improvement Technology Research Group". In addition to fitting the wheels with familiar star tires, the strong technical team also had to design a suspension acceleration system for the carriage.

Roland himself was the only layman on the team, but fortunately he had experience on Earth to draw on, and at his prompting, it only took the "all-star" team of trap warlocks to create a complete set of improvements including "familiar star twill tires" + "spring suspension suspension system". According to the old man Matvey, "this scheme not only completely improved the structure of the carriage, but even redefined the time-honored concept of the 'carriage'".

Over the next few days, Roland's technical team repeatedly tested the new carriage in different road conditions, and the results confirmed that the new carriage equipped with familiar star tires and a spring-loaded suspension suspension system had great advantages over traditional carriages in all aspects, both in terms of speed and ride comfort.

"Congratulations, Your Royal Highness, on making history once again, and it is to be expected that our new carriages and star tires will be popular all over the Far East once they are introduced to the market, and in time they will become the ace export products of the Far East, along with soaps, mercury mirrors and clocks, and even the arrogant gringos will have to compete with each other." Morozov smiled and snapped his fingers, "Brother Kafta, go and bring the bottle of champagne in the carriage, I want to invite everyone to have a drink to celebrate!" ”

"Huh?! You throw the bottle directly in the carriage and are not afraid of breaking it? Kafta was taken aback.

"In fact, it's intact, and this little experiment proves how comfortable our carriage ride is, and even if you don't trust my ass, at least you have to trust the bottle of champagne."

Morozov's witty remark drew a burst of cheerful laughter. At Roland's call, everyone raised their glasses to champagne, including Leonid and Natalia, and although they had long since lost their sense of taste, they did not prevent them from sharing the joy of success.

The problems in the technical link have been solved one after another, and the "star tires" and "new carriages" have naturally entered the stage of industrial production and commercial promotion.

Since July, Roland has been in charge of the construction of a tyre factory and a car factory in the Karon Industrial Area. At the same time, as autumn deepens, farmland across the Far East is ushering in the harvest season, and the 200 rural farm pilots that Roland focuses on are no exception. In order to confirm the effectiveness of the management of rural communes, state-owned controlled farms, and the implementation of the enterprise business model, Roland had to take time out to frequently go to the countryside to inspect the harvest in addition to preparing for the construction of the factory, and at the busiest time, he made more than ten trips back and forth from the Colasburg to the Caron industrial area and then to the rural farm, and he had to pay careful attention to eating and sleeping time, so he did not bother to personally come forward to promote the new horse-drawn carriage equipped with familiar star tires and spring suspension system.

Fortunately, the current government of Kolas is on the right track, and all walks of life have entered a stage of benign development under the appropriate regulation of the government, and new products with great commercial prospects such as star tires and new horse-drawn carriages have just been born, attracting the attention of everyone from cabinet ministers to ordinary businessmen. There is no need for Roland to wave the flag himself, a complete set of propaganda machines designed by him himself began to operate automatically, and through the "Far Eastern Evening News" and "Motherland Daily", two news platforms facing the whole country, the many benefits of star tires and new horse-drawn carriages were popularized to the general public in the form of communication reports.

These reports were not of a commercial nature, but the industrialists and merchants, who were always following the news, sniffed out the business opportunities from these reports and immediately heard the news, and they inquired through various channels to find out the inside information, revealing a strong interest in investing in this industry.

Roland's two factories, though not small, could not meet the needs of road transport across the country – nor could they be met by government funding alone – so they welcomed the presence of industrial and commercial leaders who were interested in investing. Anyway, the raw materials of tires and the technical patents of the carriage suspension system are in his hands, and opening up the downstream links of the industrial chain to private investors will not only not harm his interests, but will gain greater benefits because of the rapid growth of the entire industry.

If we look at this issue from the perspective of the country's macroeconomic helmsman, Roland argues that the introduction of industry competitors can help to reduce the market prices of related products and services, and promote the modification of the rental and long-distance carriages in towns. With the popularization of tires and new horse-drawn carriages, ordinary people will not need to spend more money to get a more convenient and comfortable travel experience than before, and they will experience the benefits of technological innovation, and thus they will also feel the efforts of national leaders, including His Royal Highness, to improve public services and enhance people's happiness.

To this day, the kingdom of Kolas has not been accepted as a full member of the Varess community, and the Far East is still a desolate and backward heretical penal colony in the eyes of foreigners. In the year since its establishment, the Kolas government has made many efforts in the field of diplomacy to change its international image, but with little success. No one, including Roland, thought that the breakthrough would first appear in the business field. The 21st World Exposition of Vares, held in Bethlehem, the capital of Canaan, in August, unexpectedly became a stage for the Far East's exhibits to shine, impressing the world with the fledgling new regime of the Far Eastern kingdom of Koras.

The "World's Fair" in Vares, also known as the "World Fair", is a commercial exhibition under the "Holy Light Alliance", an international alliance based on a common faith. The World Expo is held every five years, initially on a rotating basis in capitals, but has since expanded to other major commercial cities.

During the preparation of the World Expo, leading figures in the business community of various countries will receive invitations to participate in the exhibition and selection activities with their signature products. The expo has a jury composed of industry experts, and each edition selects the top ten outstanding products, in addition to the quality of the products themselves, but also pays great attention to the application of new technologies and processes.

Since the Kingdom of Kolas is neither a full member nor an observer state of the Holy Light Alliance, it is reasonable that it is not eligible to participate in the Bethlehem Expo, but due to the deep friendship that the Prince of Canaan and the Prince of the Far East have formed during their adventures in Akron, the "Nightmare City", this seemingly impossible has also taken a turn for the worse.
