Mechanical cars are the general name for motor vehicles such as automobiles in the Qin State, and people have a strange view of machinery, because these mechanical cars always look strange.

However, the race is only between mechanical cars. The reason is that at this time the car still could not outpace the horse's speed. Horses were still one of the main forces of road transportation in the Qin Kingdom. And these cars are either built very big. Either it's too lightweight. It looks very unsafe. Three-wheeled, four-wheeled to tracked, strange.

And these mechanical cars are much quieter than before. But it's still there, after all.

These vehicles came from the major carriage factories in the Qin State, and they had already begun to shift some of their efforts to the development of mechanical vehicles. It's like a train. One day in the future, the Qin State will definitely replace those horses with mechanical chariots.

None of the cars were able to complete the race, because many cars broke down in the middle of the race, or the water tank boiled up, or the parts were worn out so badly that the entire car was scrapped. Although the competition was not held. But it ushered in a new era in history. The state of Qin is working hard towards the age of machinery.

Compared to horse-drawn carriages, trains have undergone a major change. The first is the emergence of welding technology, so that the train boiler of the Qin State can be built bigger and bigger. The increase in traction meant that Qin's trains could pull more goods and people at once.

The second is that the researchers of the Qin State have focused their new attention on the diesel engine, which is not only lightweight, but also can burst out with several times more traction than the steam engine, not only the diesel engine, but also the tram. People are looking for a more convenient and smaller traction locomotive.

Finally, there is the track of the train. With the advent of steel rails, the Qin state began to modify some of the train tracks that had already been built, and they wanted to replace the original rails with steel rails, because the carrying capacity of trains was limited by these rails. In order to speed up the replacement and laying, the engineers of the Qin State began to think of a way to make the construction possible in winter. This method is modular cement slabs. That is, a certain model cement is poured indoors, and then transported to the engineering unit and linked according to the link points. This technology is an extremely bold and innovative idea. If successful, Qin's engineering project will greatly shorten the construction time.

On behalf of the Qin Navy, Zhang Han submitted a plan to go to sea, and the Qin Navy not only established ports, but also built ships at a very fast pace, and there was a large amount of fine timber in the upper reaches of the Yangtze River for them to use. The South began his large-scale development with log harvesting. Although there was still no faster way to get from the north to the south, the Qin state was working hard to open up this road in the next year. and build railways.

The Navy built a large wooden battleship with more than a hundred guns installed in accordance with the ship identification provided by Shangwen. Two more are under construction. In addition, there was a cruiser with fifty-eight guns, two destroyers, and a frigate. As well as twelve fast gunboats armed with one gun. These ships were larger than originally envisaged.

The number of ships under construction in the Qin State is also speeding up construction, but the personnel situation is not very optimistic. The number of sailors and crews recruited by the Qin State was very limited. At present, the situation of the Qin Navy is very embarrassing. The ship was there, but there were very few guns on board, and not only were there few guns. Even the staff is small. Large battleships required at least nearly four hundred men. But barely 200 people are on duty. There was little attention paid to the club of the navy, mainly because the ocean-going trade was not carried out, and the main resources obtained by the people came from the west and the north. and the vast outback.

Therefore, Zhang Han is very anxious about this, and he hopes that through this plan, he will greatly exchange for the government's support in the next year. It would be desirable for the Navy to be able to break out of the Yangtze River and into the ocean by the end of this year.

The plan is divided into two.

The first was more modest, and the Qin state wanted to obtain the right to use a section of the Yangtze River waterway through the Chu state through diplomatic means. If not, the Qin State would use the warships in its hands to fight a surface war on a limited scale, mainly in the Yangtze River waterway.

The main way is that the fleet will go down the river from the upstream and attack the berths of major ships. In fact, the Chu army also had a water army. And the number of his ships is as high as thousands. But their ships were old-fashioned warships. Although the Qin State was a wooden-hulled ship, it had three sails and was equipped with an advanced firing system. The Qin State devised a rope system to slow down the recoil of artillery. This makes it possible to fight a surface war in a limited space.

Although the navy of the Qin State was small, it was excellent. The Qin navy hoped to harass the other side through constant attacks and force it to give Qin the right to use part of the Yangtze River.

The second is by building large-scale small and medium-sized ships, i.e. expanded versions of gunboats, which are small and agile enough to attack each other quickly. The Navy also hopes to achieve the same purpose as the first plan with low-cost ships.

Wang Jian was an army general, and he didn't know anything about the navy, but he understood that according to the calculation of the war potential of the Chu State, Zhang Han's idea would not work. He immediately returned the plan. Only a copy was left for reference and sent to Shangwen, after all, in foreign affairs. The prime minister still has a lot of say.

The naval program was returned. Zhang Han felt that the scale of the war should be increased. And when this plan was delivered to Shang Wen, Shang Wen's attitude was supportive, but he did not support the plan. The reason is that the Qin State is underdeveloped in the south, and although the Qin State has an old-fashioned naval army and a new-style navy, it is too difficult to supply logistics.

Qin did not have a quick access to the south, nor did it have highways, roads, or railways. Moreover, the Navy lacked important weapons, artillery. The last point is that the materials of the ships of the Qin Navy are still wooden, which is compared to the Chu State Navy, Shang Wen believes that there is no advantage at all.

Analyze it technically. The new warships of the Qin Navy have a speed advantage, but don't forget that you have an advantage at sea, but this is an inland water system. The width of the river is limited, and there is hydrological and meteorological data, and the Qin State does not have an advantage, so the new warships of the Qin State have an advantage in artillery, but the number of your artillery is too small. Hungry tigers can't beat the wolves. Historical data have proved that in the Yangtze River system war, if one side takes advantage of the local hydrometeorological advantages, it adopts the method of fire attack. The consequences were catastrophic.

Shang Wen's idea is still to postpone it for a year. When there is a foundation for the development of the south, and the navy is fully equipped with ironclad ships, or steel hulls, the navy will fight again.
