Chen Cai and his family simply applied for a single application, but in the end, they attracted a construction team of more than 3,000 people, as well as steel and cement that Hongmen had hoarded for almost a whole year.

In fact, there is already a dirt road between Bengang and Da'an Port, which is used as a passage for land travel in peacetime, but because this road has to connect to the surrounding areas to connect with the location of other indigenous tribe villages, it is naturally a bit bent in planning.

Therefore, this time the new planning of the railway track road is best to form a straight connection with Da'an Port, so as to minimize material loss and control costs.

Fortunately, on the terrain between Bengang and Da'an Port, there are basically no obstructions such as mountains and valleys, and the only thing that is more troublesome is the problem of a few streams.

However, for the Hongmen Engineering Department, which now has rich engineering experience, these problems are really not much of a problem, and they are really just troubles.

The engineering department is the former chief architect of Hongmen Wan Liang single-handedly promoted the establishment of the department, and finally got the consent of Li Tianyang, but unfortunately, Wan Liang because of the early hard work, in Chongzhen five years has died of illness, and now he inherits his will is a group of Bengang school children led by Guo Shuhuan.

The role of Wan Liangqi is not small for Hongmende, it is he who has calculated and practiced the practical formula of cement building, and formulated a series of construction standards, for the concrete construction industry, it can be said that the ancestor has to exist.

Nowadays, more than half of the professional books on engineering and architecture of Bengang School are summarized by Wan Liang, and Guo Shuhuan, these Bengang students, can be said to be his heirs.

The geological survey work was actually completed a long time ago, and don't forget that Hongmen has kept several exploration teams on Dayuan Island, and their mission is not only to explore the various mineral veins on Dayuan Island, but also to survey the various topographical features of the island.

If you compare the latest map of Dayuan Island with later generations, it is not difficult to find that the difference between the two maps is not too big, at least the shape and outline of Dayuan Island are roughly the same.

This is all due to the Dayuan Island exploration team and the mapping team.

The recruitment of more than 3,000 laborers is really a trivial matter for Dayuan Hongmen, which now has a population of more than 300,000, and it is not enough to mention the strong labor of those displaced people who have just come to Dayuan Island to settle for less than half a year.

In order to take care of these newly settled people, the vast majority of these recruited laborers were recruited from these people, which can be regarded as helping them.

The construction was scheduled for the fifth day of the second lunar month, and there was no large-scale groundbreaking ceremony, etc., but after Zhang Yuyan as a representative gave a few casual words to the people present, the construction of this railway track officially began.

Chen Cai and their side have made great progress, and Yang Zhi's side has not lagged too far behind, and after having plenty of time, Yang Zhi's R&D team finally made a breakthrough in underwater sealing technology.

The breakthrough in underwater sealing technology, compared with the breakthrough in steam train technology, is actually of more practical significance to the expansion of Hongmen's strength, because this means that Hongmen will bid farewell to the backward situation of relying on wind power and manpower to operate ships in the next few years.

Is there anything more important than this for Hongmen, a team that started by relying on the ocean?

As the steam engine began to be applied to all aspects, smelters, foundries, dock loading and unloading areas, etc., began to apply the fifth-generation steam engine, which also made Yang Zhi's shipyard shipbuilding speed have been greatly improved.

The most important point is that Yang Zhi and the others have discovered a natural phenomenon a long time ago, and it is finally possible that because of the appearance of the steam engine, this natural phenomenon can be shown in shipbuilding.

The so-called natural phenomenon is actually just a very ordinary phenomenon of the subway barrel floating on the water, and the discovery of this phenomenon was actually discovered by Yang Zhi more than ten years ago, but at first everyone did not understand the reason, and then they could not find the practical value.

It wasn't until Yang Zhi became the director of the shipyard that he had always fantasized in his heart about being able to build a steel battleship that could sail freely on the sea.

Therefore, in the past few years, a large part of the dividends received by Yang Zhi and his shipyard from shipbuilding interests, as well as Hongmen's application for the research and development funds of the shipyard, have been invested in the secret research and development of steel warships.

This is the biggest killer in Yang Zhi's hands, even Li Tianyang never knew that this project existed, Yang Zhi hopes that one day when they make this warship, it will shock the entire Hongmen, and even the whole world, let people know that not only he Chen Cai is a genius in research and development, but he Yang Zhi is not weak at all!

Until now, Yang Zhi and the others have been able to build an iron ship that can carry more than ten tons of materials and float on the sea, but until now, they have not been able to build an iron ship with a displacement of tens or hundreds of tons.

The reason for this is that one of the biggest problems lies in the connection between the steel plates, and in the case that it cannot be melted and molded at one time like artillery, then if I want to build a ship with a displacement of hundreds of tons, I need to connect the steel plates one by one, and ensure that it will not break or leak.

Nowadays, in the Bengang Shipyard, Yang Zhi and the ground steel plates they use are more than three zhang long and wide, and about one and a half inches thick, and the weight of a steel plate alone has reached more than 20 tons.

However, with the application of the steam engine, according to Yang Zhi's requirements, the horsepower of the steam engine it has is one of the best in the entire Hongmen, which brings great convenience to its lifting of various high-weight raw materials.

As for how to overcome the problem of direct connection of steel plates, this problem has not been solved until now, for Yang Zhi and them, as long as there is a goal and a vision, sooner or later a breakthrough will be made.

But now, Yang Zhi's greater focus is still on the development of steam ships, and with the breakthrough of underwater sealing technology, the speed of their ships has been further improved; At the same time, the layout of their seagoing vessels has become more rational, and they are taking a big step towards the practical use of steamships.
