The beggar emperor at the end of Ming Dynasty - Chapter 580

It took more than three days to weigh the metal iron pillar by Cao Chong.

About 40000 Jin, equivalent to 20 tons, which made Qin Huan feel a little relieved.

It’s not too heavy. It can be rescued.

In order to solve the problem of flexibility, Qin Huan decided to pour another circle of cement around the iron column, the thickness of the bucket, and finally wrap a circle of wood blocks, which can not only control the weight of the keel, but also ensure enough firmness.

The metal iron core has strong tensile strength, and the cement block is not easy to deform. Combined with the shock absorption of wood block, the three elements are definitely stronger than the whole wooden keel.

All the craftsmen were shocked by Qin Huan’s idea. No one thought that the keel could still do this. It’s OK to cast it with metal. Now even cement is used.

However, they thought about the firmness of the cement after solidification, and felt that the cement pouring was not inevitable, so they were busy again under Qin Huan’s orders.

Instead of pouring on the slope, a new slipway was directly selected to build the formwork. After all, cement slurry is much easier to operate than hot metal, but the method of pouring multiple openings at the same time was still adopted.

Similarly, cement pouring is much faster than hot metal pouring. It only took three days from formwork erection to pouring. A reinforced concrete keel with a thick bucket was officially baked. The surface was painted first, then painted with copper oil, and then added with a wooden outer ring.

Qin Huan’s patience was surprisingly good this time. He lived directly in Shanghai and waited for the warship made of new keel to be launched for trial voyage.

Qin Huan didn’t hurry to standardize and let the craftsmen design the relevant process.

Because if it is really feasible, he plans to improve it by reducing the size of the iron core in the middle by half, casting six small iron cores around the periphery, a little bigger than his thumb, then connecting the seven iron cores with iron wire, pouring cement in the middle, and even leaving some steel gaps in advance to connect the ribs.

The keel poured in this way is stronger than a single iron core in any aspect, and can reduce some weight again to become a real reinforced concrete keel.

It was very cumbersome to assemble the keel and ribs. Qin Huan could not help. He just watched it for a few days and joined the team of designing merchant ships.

Qin Huan was full of energy for the great cause of shipbuilding. He fought with a group of craftsmen and completely put down the emperor’s shelf. As a result, the construction efficiency of Shanghai was a little higher than usual.

But Qian bin and Zhang Yan in Nanjing were as big as a fight. Looking at the orders from Qin Huan, they all wanted to cry without tears.

Jiangnan’s new deal has just come to an end. The Government Council is planning to focus its energy on building a national communication network, and the city shipping department has to be aggressive.

The key is that in addition to the Yangtze River, the Yellow River and the Pearl River, a Navy subordinate to the Ministry of justice should be established. Coastal provinces should also establish a navy. Even small river and sea ships may have to have thousands of ships to meet the demand, and the government council should pay the money for building ships and the cost of daily maintenance and operation.

Fortunately, in the future, merchant ships will have to charge operation tax every year, and the tax is not low. Otherwise, Qian bin will really be worried to death. After the last run, even Qin Huan repeatedly said that that would not happen in the future, he did not dare to let the central bank print treasure money indiscriminately.

Qin Huan had clearly told him that the Royal Bank would no longer be responsible for exchanging silver in the future. If the treasure money could not be exchanged for silver in the future, the Royal Bank would theoretically become a victim like other businessmen.

This frightened him, his colleagues in the Government Affairs Council and the chief executive of the central bank.

It seemed that Qin Huan would drag them out one day to calm the people’s anger.

If the amount of work of the Government Affairs Council is still a little huge, in addition to the construction of one or two wharfs, the establishment of Navy and the establishment of special yamen management in all provinces, the workload of the interior government will be absolutely boundless.

However, Qin Huan had to follow Qin Huan’s orders no matter how old he was. Originally, Qin Huan did not intend Zhang Yan and several concubines to interfere in the affairs of the house of internal affairs, but the facts proved that it was unrealistic, at least in a short time, unless he had been staying in Nanjing, so he handed over the power of the house of internal affairs to Zhang Yan again when he left.

However, the government and military affairs are absolutely not allowed to intervene. The military and political yuan and the government affairs yuan are fully responsible. In case of major events, you can send someone to Shanghai for instructions, and the express ship will come day and night.

Qin Huan’s plans were only a rough idea. After the interior government improved them, Zhang Yan decided to hold a business seminar first and invite all influential businessmen from all provinces.

Otherwise, business tax will be levied on trade, and merchant ships will be built according to the size set by the imperial court. Goods will also be packed in specified wooden frames. It is estimated that businessmen along the Yangtze River and businessmen in Jiangsu and Zhejiang will be frightened and become a pot of porridge.

For a time, businessmen from all over the country rushed to Nanjing and all used flying pigeons to deliver books. This was the first large-scale use of Flying Pigeon book network after it was established.

Compared with the road communication network, the flying pigeon book network is much simpler.

Zhang Yan finally understood why Qin Huan insisted on setting up a flying pigeon book network, because it was really convenient.

In just two days, the business seminar has been conveyed to all provinces, prefectures and counties.

Daqin is busy opening chambers of Commerce, building, researching new technologies, promoting emerging crops, building warehouses and post stations, but the frontier is in full swing.

After Qin tie entered the northeast with 100000 troops, he just took a short rest and moved eastward. Wherever he went, whether it was the Korean people, landlords, officials and soldiers, he rose up and defected one after another. In just one month, he won two northern routes. Hogg had to flee to the South with the defeated generals of the eight banners and his people to Japan.

There was no way. He wanted to surrender to the Qin Dynasty. As long as he could save his people’s lives, he would be willing to return to the mountains and forests again, but even so, he was still rejected. It was obvious that Qin Huan wanted to kill them all and never die.

Tokugawa was also surprised to see the Qin army coming. While mobilizing troops to prepare for the battle north, Tokugawa cleaned up the public security in the controlled areas and strengthened management. At this time, it would not refuse Haug’s defection.

After Qin tie occupied the two roads, he did not directly kill them to Gyeonggi road. Instead, he was busy recruiting Korean servants to join the army, while dividing troops to attack huanghaidao and take out Haikou.

On the peninsula in the northeast, a war is brewing, but on the grassland ten thousand miles away from the northwest, a war is imminent.
