The Edo government was preparing for and attacking the rebellious samurai group, and the exploration team also investigated large and small gold and silver mines in Japan. The defeated Tokugawa Iemitsu, Katsunari Mizuno, Tadao Matsuhei and others forever withdrew from the stage of Japan's competition. They were escorted to the capital of Huaxia on the Oriental.

Tokugawa Iemitsu walked out of the carriage of the "Industry" steam locomotive with a look of shock on his face. Between Tianjin and the capital, the people were no longer surprised by the railways that appeared. As long as they had money, civilians were also qualified to buy train tickets.

He saw the neat and orderly streets of Beijing and was extremely surprised by the orderliness here. Because of the establishment of the medical department, the public's medical care and health care were taken unprecedentedly. Urination and defecation on the street were listed as illegal and would face punishment of being arrested and fined by the police.

At the same time, the Ministry of Medicine organized manpower to clear the open and hidden channels in the capital, formulate a waste and sewage discharge system, so that the capital city will be transformed and evolve from a classical city to a modern city.

These greatly stimulated the shogun prisoners such as Tokugawa Iemitsu. At this time, Edo Castle was also in a classical city and was definitely not so neat.

On both sides of the main city road are neat telephone poles, and the distance between each pole is almost the same. Some streets are closed and roads are being paved, and some places are building cement buildings. Among the flat and small wooden buildings that are beyond the end, there are more than three high-rise civil buildings.

There are also further afield where you can faintly see the chimneys of the factory vaguely emitting black smoke, sank into the air.

"The amazing city cannot be compared with Edo Castle." Tokugawa Ie-Ku sighed.

The capital cities that emerged in modern and modern cities began to surpass the classical cities of this era, making other cities only look close to them!

"This street has been blocked by the government, please come here." The officer who escorted them said to Tokugawa Ieguang and his group.

They were going to walk on the main road, but one section of the main road was sealed up, with fences in front and behind and police officers responsible for guarding the road surface, and it seemed that there were still workers busy.

Are you building a road? Before turning the bend, Tokugawa Iemitsu curiously looked at the blocked section with his light and found that there were indeed workers building a road.

But what surprised Tokugawa Iemitsu was that the pavement surface that workers were paving was gray-black, which was completely different from ordinary dirt and gravel roads.

"What kind of stone is used to lay the sealed section? Why is it gray-black? Could it be that such a road is easier to travel?" Tokugawa Iemitsu Army officer who was escorting them.

"This is called a coal tar gravel road. It is very complicated, and I can't explain its principle. Its cost is more expensive than ordinary gravel roads. I don't know the benefits. I heard that it is not easy to seep water, and it will not be muddy on rainy days." The officers who led them did not understand that coal tar is artificial asphalt. They used the coal tar distillation technology to make complex compounds, but they just roughly knew what it was.

There are many things that they don’t have to and cannot know all the principles. As non-technical experts, they only need to know the pros and cons of them and use them calmly.

Tokugawa Iemitsu, Mizuno Katsunari, Ikeda Mizumasa and others looked at each other, unable to understand what kind of object the coal tar gravel road is, and they can only regard it as a special gravel road in their hearts.

The coal asphalt pavement began to be paved in Beijing, and the cost was much more expensive than usual gravel roads and dirt roads, but Chu Yun still developed this technology and put it into use without hesitation. Because coal and corresponding coal by-product processing technology constituted the energy source of Jiuzhou military industrial technology and provided energy for the steam engine.

When developing coal use technology, the coal asphalt technology was also accidentally opened by Chu Yun, and it provides suitable road surfaces for future automobile production. Asphalt roads are more suitable for automobile exercise than ordinary dirt roads and gravel roads.

In fact, asphalt pavement was paved in the UK, France and other places in the early and mid-19th century before the emergence of cars. Shanghai City in China only had the first asphalt gravel road in the early 20th century.

Before the oil technology was launched, Chu Yun used coal-related technologies, and coal asphalt technology became the first choice at present. In addition to coal asphalt technology, there are also petroleum asphalt and natural asphalt, which are not practical for the time being.

Tokugawa Iemitsu and others were surprised by unknown things like asphalt, and were deeply afraid. The technology in the capital seemed to be developing too fast, as if a bunch of novel things suddenly appeared. This was somewhat inconsistent with their impression of the Celestial Kingdom that was once banned by the sea. Now China's ambition to expand outward is stronger than the island countries they are trying to seek development outside.

"You will stay here for a few days. When will our army master want to summon you? I will take you to visit him." The officers who led Tokugawa Iemitsu and other shogunate captives led them to the houses where the envoys from various countries and officials from all over the country came to Beijing to place them.

Tokugawa Iemitsu and others have a special identity. Although they were prisoners of war, they were defeated in the Japanese civil war and did not have direct conflicts with the Chinese mainland. Therefore, their treatment was better than the nobles of the South China countries who directly fought with the Kyushu Army.

After they were taken to the capital, they were unfamiliar with the place and had almost no chance of escaping. Even if they fled back to Japan, they would face them the wanted warned by the new government, and they would be homeless.

The temporary residence of Tokugawa Iemitsu and others was a common courtyard house in the capital. After the officers of the Kyushu Army left, more than a dozen important prisoners of war finally had the opportunity to chat in private.

"Mr. Master, I think their capital seems to be really helping God. It's only forty years before the Battle of Wenlu, and they have produced many strange things. Although after the Battle of Wenlu, we were busy with civil strife and had no time to send people to pay attention to the development of the Supreme Kingdom of the Celestial Kingdom, it is incredible to have such technology in the past forty years." Katsunari Mizuno said.

Many of the important officials present had participated in the invasion of Goryeo and fought with the Ming army. Although the Warring States Army represented by Toyotomi Hideyoshi at that time was defeated and its technology was still far from the Central Plains, they remembered that the Ming army's technology had not reached a complete crushing point. As a result, forty years passed, technology that exceeded that of this era of a hundred years suddenly emerged in mainland China. Various new firearms and inventions emerged, making the Edo Shogunate, which had not made much progress forty years ago, feel incredible.

"Taki Sakai once led an envoy to visit here. Their rulers were about the same age as me. If they could revive China, they should have a destiny." Tokugawa Iemitsu could only blame the sudden increase in technology gap between the two sides on destiny.

However, his guess is almost the same. Who made Chu Yun have a technology system from the future?
