The three brothers of the Qian family brought back by Liu Ye also played a big role. With their experience and ability as businessmen, they established the first chamber of commerce in the capital after obtaining Liu Ye's approval.

The current role of the chamber of commerce is simple: to provide a guarantee for the 'exchange' of each item, to clearly mark the price, and to provide a place for the 'exchange' of meetings.

The emergence of the Chamber of Commerce was Liu Ye, who borrowed from the wasteland assembly and witnessed the prosperity of the assembly, and Liu Ye also came up with the idea of establishing a small assembly.

This idea hit it off with the three brothers of the Qian family, and they immediately made suggestions, so there was the prototype of the current one.

Although the function of the chamber of commerce is still very simple, Liu Ye believes that with the strength of the capital, the function and influence of the chamber of commerce will become greater and greater.

Liu Ye is deeply aware of the difference between the identities of the participants and the organizers, and although the participants can get certain convenience and benefits, they will definitely be exploited by the organizers.

Just like the six northern cities, they only need to organize it, and they can get a lot of supplies, which can be said to be effortless.

The appearance of the Chamber of Commerce is very popular with the citizens of Dadu, firstly, they can experience what the famous wasteland opportunities are like, and secondly, there are indeed many problems in the previous 'exchange' of Dadu.

Often the same thing, because of the different needs of the 'exchange', can often be 'exchanged' for different prices. This kind of 'exchange' is often irreversible, and sometimes too much disparity can cause a lot of disputes.

These disputes seem to be trivial matters, but once they accumulate, they will slowly take root in people's hearts.

The emergence of the Chamber of Commerce is in response to the situation, not only open and transparent, but also Liu Ye took the opportunity to unify the standard of 'exchange' and put forward the concept of equivalent 'exchange'.

Considering that heavy metals can no longer meet people's needs, Liu Ye set the equivalent 'exchange' as three things: bullets, grenades and nuclear batteries.

The approximate price of "handover" is as follows: 100 rounds of ammunition can be "exchanged" for one grenade, 100 grenades can be "exchanged" for a miniature nuclear battery, and one miniature nuclear battery can be "exchanged" for 10,000 rounds of ammunition.

As for the nuclear energy battery, according to the four types of large, medium, small and micro, the decimal system is used as the 'alternating' grade. For example, ten miniature nuclear batteries can be 'swapped' for one small nuclear battery.

At first, people were a little uncomfortable with such a price, but after Liu Ye forced it for a while, people gradually discovered the benefits.

Many unnecessary disputes have completely disappeared, because the root cause of many disputes is due to the unclear and cumbersome "exchange" of units. Nowadays, it is transparent and fixed, and people have rod scales in their hearts, and the efficiency of 'exchange' has been improved a lot.

In addition, the emergence of the chamber of commerce has directly spawned a group of people who rely on the 'exchange' price difference to make profits. By chance, they found that buying at a difference and selling at a high price could bring them a lot of profits, so they started a similar business.

This part is the prototype of the businessman, which can be regarded as the companion of the three brothers of the Qian family. But Liu Ye did not want these people to sit on the throne now, but he deeply understood that business must be built on a deep agricultural and industrial foundation.

In the current social form, if they grasp too many resources through the price difference, it will affect their own rule, and even 'disrupt' the social form.

Therefore, Liu Ye only told the three brothers of the Qian family to secretly monitor them, absorb them into the internal management of the Chamber of Commerce, and not allow them to hoard Juqi. Once discovered, the functions of the chamber of commerce will be used to adjust and reduce the value of the 'exchange' of the materials in their hands.

At the beginning, there were indeed a few people who had such thoughts, and after the money in their hands increased, they became angry and did not pay much attention to other people. But after being suppressed by Liu Ye, he gradually understood the reason, honestly behaved with his tail between his legs, and started a small business dutifully.

But even so, the material wealth of these people is higher than the average of others. Many people were red-eyed when they saw this, and they also wanted to enter the chamber of commerce to do such a business.

However, Liu Ye expected such a result in advance. From the outset, he limited the number of such persons with the corresponding merchant certificates, and issued only three such certificates per year.

It is also very difficult to get a certificate, and it must be recognized by the owner of the chamber of commerce. In this way, the enthusiasm of the city residents to become merchants was greatly reduced, and they could earn a lot of income from their work anyway, and everyone became more steady.

Seeing this, Liu Ye slowly put his mind at ease. After all, now the agriculture of the capital has just started, if a bunch of people run to become merchants, then the farmland of *** will be uncultivated, and the development foundation of the capital will collapse.

As soon as Liu Ye came back, he came up with three new things in a row, the establishment of the Blaster Regiment, the establishment of the Dadutang education system, and the rise of the Chamber of Commerce.

Although each of these measures did not make the capital city develop by a leap and bound, these three new things made the citizens 'refreshed', and they vaguely felt that the development of the capital city would be completely beyond imagination if this continued.

However, Liu Ye's next thing directly strengthened their feelings.

Liu Ye lifted out a huge iron bump and asked the terrier to help repair it. The lump actually moved, and it also moved several other machines in an abandoned factory in the city.

I heard rumors that that iron lump was a broken *** pulled by the city lord from Area C, what is it called a medium-sized generator. The abandoned factory that was driven into operation seems to be called "Huaxia Iron and Steel Factory" according to the identification of several literate city residents.

Hardly any of the city's citizens knew what steel was. The only thing the townspeople had of was that the long rusty iron rods near their houses seemed to have something to do with steel.

Either way, the citizens of the capital have a hunch that their lives may change again.

In particular, the group of people who had just been absorbed into the Chamber of Commerce were keenly aware of the value of those scrap iron rods, and immediately secretly bought them. There are a lot of this kind of things in every household, and they are generally sharpened as steel spears, although they are useful, they are not as effective as those in their hands.

Therefore, many people didn't think much about it, and they 'handed it over'.

Liu Ye did not stop the actions of this group of businessmen, after all, there is no trace of the eight characters yet.

Soon, the group of merchants collected nearly 65% of the scrap steel in the capital. Even the three brothers of the Qian family admired the boldness of these people, they can be said to have 'spent' their families to collect these steels, and once the investment failed, it was really useless. At present, even the three brothers of the Qian family have not understood what these waste iron rods can be used for.

Just when the businessmen were frantically buying steel, Liu Ye was standing in the Huaxia Iron and Steel Plant with a black face with a black face, excitedly waiting for what was about to happen.

Fifteen men took turns leading truckloads of coal into a large furnace that burned red like magma underground.

In the front is a knife-shaped iron mold, and in the back is connected to an abandoned generator that Liu Ye pulled from Area C.

"Let's get started!" Liu Ye glanced at Nan Tiancheng and said.

Nan Tiancheng nodded cautiously and forcefully pulled down the rusty gate in his hand.

A humming sound rang out, and the generator spun around, and the furnace in front of it seemed to be infused with a force that burned even more red.

Liu Ye threw a piece of scrap steel that could be seen everywhere in the capital into the furnace, and the scorching temperature hit, except for Liu Ye, Feng and Ruiyan, everyone couldn't help but take a step back in unison.

The piece of steel slowly became red under the burning of the high temperature, and there were several black bear guards wearing shorts next to him who were sweating profusely pulling a huge bellows.

Several new types of seams on the bellows are obvious, and they look like they have just been manufactured.

Strong winds blow into the furnace from the bottom, and the steel melts faster. After about twenty minutes, the piece of steel turned into a liquid-like substance, flowing slowly.

Ignoring the terrifying heat emitted by the furnace, Liu Ye stepped forward, pressed the handle of the furnace, tilted it open, and introduced it into the knife-shaped mold in front of him.

The fiery molten iron flows into the mold, making a slight sound, and gradually condenses and forms under the action of low temperature.

"Good! Almost! It's time to take it out! ”

Seeing that the steel gradually regained its form, Liu Ye immediately clamped it out with pliers, put it into the cold water next to it, and shook it up and down slightly.

As he shook, a puff of green smoke rose and the cold water boiled.

Three minutes later, Liu Ye took out the knife-shaped mold, opened the grinding wheel next to it, and polished it.

Mars raged for a while, and although the rest of the prop was still rough, the cutting edge was already open.

Liu Ye took the end of the knife and slashed at the bone the thickness of a small thumb next to him, and after the click, the bone immediately split in half.

"Well, the edge is not very flat, but the hardness of the steel should be enough! In the future, we can only start from the tenacity 'sex' aspect to continue to improve the sharpness! Liu Ye picked up the knife and looked at the uneven surface and thought to himself.

The prop in his hand is a trial knife made by Liu Ye according to the previous soil method and then using the machine in the steel mill.

Because the generators still did not have enough power, they could only start some small equipment, and the furnaces could only barely run under the power of the coal mine and the power generation.

But if you want to start up the other machines in the steel plant completely, a generator is not enough, you have to build a power plant.

Liu Ye has always had the idea of building a power plant, but he lacks the corresponding conditions, and it seems that it is possible at present.
