According to Zhu Beiguo's diary, during this period, although many people ambitiously submitted various business plans to the Supreme Executive Committee, Xiao Han's department store plan was the first to be approved by the plenary meeting.

A few years later, his "Ledi Supermarket" opened all over Nanyang and gradually went global, earning a huge industry for himself, his children and grandchildren and all the shareholders of the crosser, and becoming an international large-scale multinational retail business empire.

However, the beginning of this business empire was a small department store located outside the gate of Sunflower Girls' College not long after, with an initial capital of only five hundred taels of silver, and there were only two people in total, including the boss of Xiao Han, and the Han girl named Tea Girl.

A few months ago, she was caught by Boss Xiao Han, and a few years later, the tea girl was eighteen years old and became Boss Han's wife......

Of course, that's another story.

The story goes back to the present, no matter what, in the mines and factories, the labor enthusiasm of the Han people has indeed greatly relieved the burden of the traversers and liberated all the traversers physically.

However, this does not mean that everyone has become idle, because each of them has invariably started their own career and life planning, they have a higher level of career to do, in short, it is impossible to be idle, with the gradual take-off of everyone's respective careers in the future, these people are afraid that it is rare to be idle in this life.

Today, in addition to the science and engineering men who are working hard in the cave and the doctors who are working intensively on the development of medicines, all the crew members are also supporting two other big projects: the coal and coke chemical base next to the glass factory, where pyrite boiling furnaces and cupola furnaces are being installed. Another project is the mechanical repair factory and glulam factory built by Boss Luo outside the cave.

In these days, the three members of Huali Quanzhenhai An Hengtong of the metallurgical group and the 30 crew members of the Supreme Executive Committee to support them were busy working at the installation site every morning.

The members of the metallurgical team were determined to complete the installation of the two pieces of equipment before the crew went to sea, and the three of them wanted to slow down the earth's rotation and create more hours a day to work.

During that time, just like Wei @ Hong complained about: These vampires just want to squeeze us during this time.

Ren Ke agreed, and said that it was like holding a whip a few more times before the little donkey got down the grinding, and it was a reason to let the donkey run a few more laps before he was willing to unload the grinding......

From this, you can imagine how intense the work of these young people has been during this time.

At the same time, it was not easy for the crew to support another project, their main task was to help the mechanical team with the infrastructure, and there were many infrastructure tasks in the machinery factory and plywood factory, although they had the help of construction machinery, but the level of fatigue was not much different from the training of sailing.

Recently, in addition to helping with the construction of the glass factory, Boss Luo and his main focus are on the two factories outside the cave gate.

Of course, this is also because of the urgent need for overall construction, because during this period of large-scale construction, the mechanical group received a lot of "business orders".

When the mechanical repair factory was still in the blueprint stage, Cao Limei came to place an order to produce a human-powered rail transporter for the mine that was lighter than the standard wagon.

Because of the factors of oil and maintenance, construction machinery can no longer be used for large-scale transportation operations in the mine.

The feeder rails of the mine were built with karst cave materials, and there are still nearly 40 kilometers of rails and sleepers left.

Cao Limei predicts that with the gradual development of various mining sites, about 10 kilometers of new branch railways will be needed, and it is clear that there is no problem with the labor and materials to build the railway, but what is lacking is rail transport vehicles.

As for the tricycles and bicycles in the cave, most of them have been used for other purposes at present, especially the tricycles, Gu Jin plans to equip some on the Nicole, mainly for the transportation of the newly built dock on Zixia Island, and the bicycles are intended to be used by the traversers themselves, and these vehicles are not suitable for the transportation of the mine.

Obviously, the mechanical group cannot be expected to build steam locomotives and supporting carriages immediately, so Cao Limei's solution for ore transportation is to produce human-powered rail cars and supporting small wagons.

This is a light rail car called a hand-cranked car, with four wheels, driven by levers, crankshafts, gears and other mechanical devices, which can tow several light carriages, operated by four people, and the speed of a single car can reach 20 kilometers per hour.

Because the project is about saving labor, reducing labor intensity and improving mining efficiency, and can also solve the problem of short-distance light-haul transportation by railway without steam locomotives for the time being, Cao Limei submitted the report to the Executive Committee early on, and requested that it be discussed and approved at the plenary meeting.

After consulting with the industry leaders, the committee found that the rail car could be used not only to transport ore, but also to carry people, especially in some short and sporadic transportation of goods and people.

At present, although there are two Stephen 040 tank-type steam locomotives on the entire Ninth railway line, only one is actually running on the railway, due to the lack of drivers.

Chengdong and Huanghai are now very busy, and the latter has to follow the Nicole to the sea, so in this case, the human-powered rail car becomes important, which can relieve the pressure of railway transportation to a considerable extent, especially the feeder transportation between the factories, and it is also economical.

The benefits were obvious, so at a regular general meeting, Cao Limei's proposal was successfully passed, and the Supreme Executive Committee handed over the task of building a human-powered rail car to the mechanical team led by Boss Luo.

And the mechanical group also took this order very quickly.

Previously, they had already rejected many production requests from all sides.

In the past, the mechanical group really rarely took orders for production, except for the necessary maintenance work, they were all focused on their own factories and replication equipment, if it was not very necessary, the mechanical group usually did not accept external orders, the reason is simple - it is not worth it.

In fact, order production itself is not a problem, the processing equipment in the cave is very complete, and the processing capacity is also very strong, but the only problem is to consume valuable industrial materials from the old world, and the consensus of the members of the mechanical team is that these valuable materials should be used for replication equipment and industrial localization, rather than for the production of these low-value and consumable tools.

Therefore, the problem faced by the mechanical group is not the question of whether it can make any equipment now, after all, the machine tools, technical data and raw materials are ready-made, and what else can't be done?

The task faced by the mechanical group is how to replicate these industrial machine tools, and to be able to develop independently in this new world, and to maintain a fairly strong mechanical processing industry capacity when the equipment and materials brought by the old world are exhausted, which is a matter related to the long-term and fundamental interests of the great cause.

Therefore, unless it is absolutely necessary, the two backbones of the mechanical group, Luo Zhengyi and Wang Xue, have been unwilling to consume the equipment and materials in the cave to take orders to make any production equipment.

Therefore, in addition to the necessary daily mechanical maintenance and equipment installation assistance in several factories, the mechanical group usually does not take orders, so that it has been almost three years since the crossing, and the mechanical group has guarded a large number of processing equipment, and has only assembled a few sugarcane harvesters for Lao Wang, and assembled and manufactured two winch lifting equipment for Wang Gong's slipway.

As for this rail car, it is the third task that the mechanical group has received so far, and Boss Luo also emphasized that this is the last task of the year.

Since the fleet went to sea, the mechanical team has been in full swing to start their own business, and their latest achievement is to successfully replicate a simple general-purpose lathe and two Iowa manual rifles using the metal materials brought back by the fleet.

Of course, the equipment is extremely rudimentary, the base of the lathe is actually cement, there are some problems with the machining accuracy, and the tools, bearings and power parts are still old world materials, but this is quite good, in short, it is an exciting start.

For Boss Luo Chengdong Huanghai, although the human-powered rail car on the railway is a very ordinary and simple vehicle, there are a lot of mechanical processing equipment involved in it, and a lot of various materials are consumed.

But Cao Limei's reason is very good, just like the original sugarcane harvester for everyone, it is an order that is not easy to refuse.

In fact, it was purely helpless to make sugarcane harvesters at that time, and the single dogs, including the mechanical group itself, wanted to let the island have a population, a woman, and a labor force as soon as possible, and then make a fortune and marry Bai Fumei to embark on the pinnacle of life, these are already the basic public opinion that permeates the hearts of all adults, if the mechanical group does not want to become everyone's public enemy, then it must be accepted!
