Early the next morning, Zhao Xin was ready to set off again, this is the last inspection, according to the progress of the project asked yesterday, today, the work of hoisting cement prefabricated parts of the entire bridge deck will be completed, the laying work, yesterday carried out a part, today will complete almost most of the link part, and then after pouring, waiting for the process of condensation.

Today's inspection is destined to not last long, Zhao Xin has been in Bianliang for a long time, and if he stays any longer, it will not be more useful, although in Bianliang, the distance between him and the concubine is closer, but Zhao Xin can't enter the palace casually, let alone enter the harem, if you simply communicate, relying on the developed logistics system of the Ding Navy, you can guarantee that you receive a letter in 3 days.

Taking advantage of the morning, when it was easier to get out of the city, Zhao Xin quickly went out of the city, but as soon as he walked out of the city, he met Han Qi.

Of course, Han Qi didn't pass by here by chance, he did it on purpose, he inspected yesterday, so he gained a lot, and after returning to Bianliang that day, he summoned the person in charge of his subordinates to discuss the half-finished fortress and the use of cranes.

The semi-finished fortress, this is just a certain adjustment to the existing fortress, and some steps have been reduced.

The craftsmen who can build the fortress, as long as they have such an idea, according to this idea, they can also get similar results, and even to some extent, it is better than the solution given by Zhao Xin, but the crane is different.

Although Zhao Xin gave Han Qi a brief description of the role of the crane, this theory, as well as the pulley block in the crane, is still very unfamiliar, even if Zhao Xin played the package ticket, this is very simple to use, as long as you understand the method of use a little, and then cooperate with each other, you can finally use it.

But he doesn't understand or doesn't understand, and even very unfamiliar, in this case, how can he rest assured.

Han Qi himself is just going to watch for a day, what is there to see about repairing the bridge, although Ding Haijun's construction method is very good, saving a lot of manpower and material resources, and the speed is quite fast, but it is enough to watch for one day, there is no need to look at the next day.

But he couldn't figure out the working principle of the crane, which made Han Qi a headache, he discussed it with the staff, and selected two younger and clever ones from the staff, and wanted to take advantage of the crane's work interval to operate.

Seeing Han Qi's convoy, Zhao Xin was also a little surprised, after knowing Han Qi's purpose, Zhao Xin also agreed, this thing is a gesture, maybe yesterday, because the workload of the crane is relatively large, there is not much time, but today, it will take half a day at most, under the premise of being able to complete all the work, there is not much problem in the experiment.

Han Qi is one of the few officials favored by Zhao Xin in the entire Northern Song Dynasty political arena, Ye Qingchen's ability is not low, and even in some aspects, he has a common language with Zhao Xin, but he is used to being relatively conservative and is not easy to accept new things.

Zhao Xin also told him about opening a bank and establishing a credit currency system, but Ye Qingchen did not say anything.

Credit currency, in the whole world, also began in the Northern Song Dynasty, the Northern Song Dynasty had a huge economic system, and the commercial activities of the people were quite active, but the basic currency of the Northern Song Dynasty was copper.

China is a country with a lot of land and resources, but in some major minerals, it cannot be called Bo, for example, high-quality iron ore, such as copper, with copper coins as raw materials, the entire Northern Song Dynasty, at least tens of billions of copper coins, to be able to support the entire huge market.

Tens of billions of guan, that is hundreds of billions of kilograms of copper, hundreds of millions of tons, for the Northern Song Dynasty, this is a problem that cannot be solved at all, for the time being, the entire Northern Song Dynasty, the total amount of copper coins, that is, hundreds of millions of guan, the serious shortage of money supply, has affected the basic economy of the Northern Song Dynasty.

Various alternative currencies began to appear, such as iron coins, dangwu, and even jiaozi, which were in fact helpless choices.

If the economic foundation of the Northern Song Dynasty, coupled with the reasonable number of issuances and exchange methods, this may not open a new chapter, and the income from the simple minting and issuance of coins can support a considerable aspect of the Northern Song Dynasty's finances, and the financial deficit of the Northern Song Dynasty will not deteriorate to this extent.

Without a co-ordinated monetary vision, or even knowing economics, after the issuance of Jiaozi obtained the first batch of benefits, the government began to regard Jiaozi as a solution to the problem, without considering the actual increase in issuance, and frantically increased issuance.

At the beginning, it was still relatively sought-after, almost a novelty Jiaozi, and soon declined.

Of course, in this era, there have been no problems yet, Jiaozi is basically popular in Sichuan, and rarely appears outside, but Ye Qingchen still doesn't dare to make up his mind easily.

On the one hand, the Dinghai currency is exquisitely made, even if it is the official of the Northern Song Dynasty, there is no way to complete the copy, on the other hand, it is because the currency of the entire Northern Song Dynasty is insufficient, not to mention a little bit of Dinghai currency, even if it is 10 times, or even 100 times, it doesn't matter.

Zhao Xin himself pinned his hopes on letting the three divisions take the lead and set up a bank similar to the issuing bank to coordinate the entire financial affairs, as long as it is slightly adjusted, it will play a higher role than the current Dinghai Bank, which is very helpful for alleviating the capital crisis of the entire Northern Song Dynasty.

Ye Qingchen's conservatism, in fact, is a waste of such an opportunity, some of Zhao Xin's practices are definitely more radical than the entire Northern Song Dynasty, such a radical approach, of course, will cause a little more conservative officials to be very uncomfortable, even if it is Han Qi, it is impossible to accept it all, let alone Ye Qingchen.

But Han Qi is much better than Ye Qingchen in this regard, compared to Ye Qingchen, who is a little more conservative, as long as there are clear benefits, or interests, Han Qi will do it, this is worth affirming, such a character and habits, it is easy to go to a high position, even in the future, after Zhao Xin's goal is achieved, when he takes enough chips from the periphery and then obtains the authority of the Northern Song Dynasty, such a relatively open and capable Zai Fu can also be used.

One party is intentional, one side is intentional, and the two sides quickly reached a consensus, and once again moved forward to the construction site, but compared to before, this time the lineup is much larger.

Before he saw Zhao Xin, Han Qi was also at a loss, he was also afraid that Zhao Xin would shirk it, and after getting Zhao Xin's affirmative reply, he relaxed a lot.

In two days, Han Qi and Zhao Xin visited the construction of the bridge, and the bridge built like building blocks was almost completed at a speed that could be seen by the naked eye.

As for the two selected staff members who will be crane operators in the future, they also have a simple understanding of construction, which they heard from Han Qi before, which is completely different from what they see now.

The cement they heard about hoisting before, they thought it was about 1,000 catties, or even a slightly larger boulder, but now they see it is completely different, this is completely tens of thousands of catties, or even a larger boulder.

This is not wrong, every time 8 cubic meters, that is, about 20 tons, is not 40,000 catties, this is traditional, that is the power that human power cannot reach, dozens of people, hundreds of people, may not be able to move.

However, the crane was able to pull them up with the labor-saving pulley, and they couldn't help but be happy at the thought that they were going to operate such a powerful thing.

It's a pity to wait, according to the agreement between Zhao Xin and Han Qi, this morning, the construction of the entire bridge prefabricated parts will be completely completed, and when the time comes, some basic materials will be transported, such as cement, steel bars and some iron tools, cranes will be used.

This kind of use, which is looser, does not require much speed and accuracy, which can be manipulated by them.

Sure enough, at noon, after all the prefabricated parts had been put into different positions, under Zhao Xin's order, they began to be replaced.

Each crane, generally has two positions, one main and one secondary, is also used, and a tryer with the help of a senior person carries out the operation of the crane.

The operation of the crane, because of the relationship between Zhao Xin, pays more attention to the operation, up and down, left and right, very distinct, and the adjustment is a little more complicated, for normal intelligent businessmen, a little proficiency and guidance, you will understand.

Seeing his subordinates, he stumbled and started the operation, Han Qi looked at it with interest, but after a while, he was a little bored, and there were many failures, even if he succeeded, it was dull.

The operation of a crane is not a show-off, it is about stability and efficiency, not cool, of course, there is nothing to look at.

At this time, the construction of the bridge deck began, and a large number of people gathered on the bridge deck, which made Han Qi interested, and in only two days, he basically completed the prototype of the bridge, even if it was just a short bridge, it was also very interesting, and he would even be interested in walking around the bridge.

Even if it is not completely bonded, some preset mechanisms, so that the iron ring and the different parts of the prefabricated parts, are perfectly combined, and already have the strength to cross the pedestrian, in the future, when the layers of cement, after the condensation, will form a fairly strong bridge.

That's the real bridge, the bridge with a strong load-bearing capacity, the railway bridge, compared to the general bridge, and even some ancient legendary bridges, the load-bearing capacity is much stronger, the reason is his use.

Not to mention the weight of the rails, sleepers, and other railways themselves, the weight of the train itself, because the whole carriage, unlike the carriages of later generations, reached 60 tons, which was so terrible, and the strength requirements for the carriage were very high.

The weight of 15 tons, as long as it is slightly reinforced, it can have a high-strength steel plate, and the weight is not so large, but the weight of a simple carriage is at least about 7 tons, plus horses, and other ancillary equipment, the weight of a carriage is at least about 30 tons.

This level greatly exceeds the weight of ordinary pedestrians, and even some new four-wheeled carriages will not have a high total weight.

When the cement is not condensed, and after condensation, the strength between them is absolutely different, but even if the cement is not condensed, it is enough to withstand the huge weight of the prefab.

On the other hand, those Han Qi's staff, their progress is very good, 10 cranes, already ready to be delivered to the Northern Song Dynasty, Han Qi brought the staff, will also become the first batch of people to operate the crane, for them, Ding Haijun's skilled people, there is no secret, even some small skills usually summed up, also taught one by one.

Because of the simplicity, this manipulation is only under the premise that the animal provides power, and begins to transport things from a low place to a high place at a certain speed, and then transports them to a suitable position through the movement of the arm and position, which is full of novelty for these operators.

A day's time, in such a visit, very fulfilling passed, Han Qi gained a lot, he got to know the personnel sent out, and knew that they had basically mastered it, and they might not be able to implement it alone, but if you explore it, you can still do it.

The operation of this crane is very simple and intuitive, and the adaptability is very good, even if no one imparts experience, you can get started quickly, and the effect is outstanding, the largest of which weighs 500 stones, that is, about 25 tons, which is much higher than they estimated before, I don't know how much.

Han Qi was satisfied, he could finally put the new style of fortress into actual combat, in the future, in a short period of time, a large number of such fortresses will be built, and even in the war, it will be accompanied by the increase of the war pattern, constantly extending forward, giving strong support to the army.

Han Qi packed up, he was going to put forward this in the next regular meeting of the Privy Council, and put the fortress system currently under construction in the north from a finished product to a semi-finished product, reducing the defense at the same time, but also greatly reducing the cost, and at the same time, the crane will be placed on the northern border.

According to the agreement with Ding Haijun, it will be provided every 2 months, so that although it has taken a little longer, the excellent performance of the crane is enough to make up for all this.

Han Qi came with Zhao Xin, but when he went back, Zhao Xin did not go back with Han Qi, and Zhao Xin's purpose of coming to Bianliang had been achieved.

After the Spring Festival, Zhao Xin should have left, this time to Bianliang, the time was more than 40 days, of course, a lot of things have been done, whether it is the sales of new products in Bianliang, or the landing of the railway project, have basically achieved the goal, cure in this process, how much money has been invested, for Zhao Xin, it is not a big problem, in this case, returning to Bianliang, is a waste of time, going back is the most correct choice.
