After receiving Lao Zhu's reply, except for a certain loss that was not accepted, Lao Zhu agreed to most of Zhu Yuan's requests and opinions.

On the side of Mingzhou, the Navy Governor's Mansion and the Camp and Sea Division have also become more busy.

Moreover, in order to make the communication between Jinling and Mingzhou more convenient, Lao Zhu also asked Wenzao to organize three teams of people to ensure that as long as needed, letters can arrive in the two places every day.

In mid-May, the third batch of grain convoys also began to go to various places to load grain, as well as another 100,000 quintals of fish that were planned.

It is expected to choose the right time to go to sea in late May.

On May 24, news came from Shandong that the second batch of grain convoys had finally arrived, compared with the first batch of 13 days, the second batch of grain convoys departed from April 29 to May 21, the whole journey was 22 days, although the time was longer, but compared with the estimated longest period of 45 days of Yinghai Division, it was still quite a smooth task

However, because of the long time and the wind and waves encountered on the way, the loss was more than the first time, and there were nearly 12,000 stone of grain in the whole process, or left the team to dock, or sank for some reason, and the loss ratio reached 6%.

The number of which sank directly was 3,700 stones.

In any case, it is still far from acceptable.

From the beginning of May to the end of this month, there is no strong wind and waves that can not go to sea, and the sea fishing fleet follows the big yellow croaker group all the way to the north, and has gradually turned from the yellow ocean to the Daiqu ocean, and then to the north of the big sea.

Compared with the Huang Dayang and Daiqu Yang near the main island of Zhoushan, in this era, the Daji Ocean in the north used to be a dangerous place that fishermen would not easily set foot in.

This time is different.

Not only did the Yinghai Division and the Navy Governor's Office send a large number of nearby support teams, but the two major yamen also built navigation lighthouses and anchorage ports on Dajishan Island and Xiaojishan Island in advance, as well as the nearby Dajishan Island and Xiaoyangshan Island and Shengsi Islands.

In addition, Ojisan Island is less than 50 miles away from Matsue Prefecture due east, and under the operation of the Yingkai Division, Matsue Prefecture also set up a lighthouse and repaired the port of mooring.

As a result, the fishing grounds of Daji Mountain, centered on Daji Mountain, have no way except for the north, and there are lighthouses and ports in the east, west, and south, within fifty miles. If the weather is fine, you can see the smoke column or lights in the distance.

Not to mention the island itself.

Because of the special location, the Navy Governor's Office specially set up a 100-household office on this 100-acre island, and planned to transform the entire Dajishan Island into an emergency stop and temporary transfer station.

In addition to the port call, a number of barracks will be built on the island to withstand hurricanes.

It's also about preparing for the future.

Starting next spring, the fishing team will continue to go north to catch small yellow croaker in Sheshan Ocean, which was once a fisherman's choice but would not easily set foot in the northern part of the Daji Ocean.

Sheshanyang, a radius of 100 miles, wants to dock in case of trouble, in addition to the Sheshan Island named after Sheshanyang in the sea off Chongming, and then it is Dajishan Island.

May twenty-six.

Compared with the interval of more than a month between the first batch of grain convoys and the second batch of grain convoys, this time, after all aspects were more and more perfect, the third batch of grain convoys set off again five days after the second batch arrived in Shandong, taking advantage of a good southwest wind.

This time, it was Zhang Cundao, the senator of the Navy Governor's Office, who led the team, Hua Gao's nephew Hua Yue as the deputy, and the number of soldiers was still 3,000, and the number of people increased to 9,000, plus the other officials of the battalion and sea division who accompanied the ship, totaling more than 12,000 people.

According to the arrangement, the Navy Governor's Office has issued an order to Shandong, and after handing over the grain, the commander of the battalion Haiwei only needs to send 1,000 soldiers to return with the people, and the remaining 2,000 elite soldiers, together with another 3,000 people, will lead some ships around the Shandong Peninsula and dock at Laizhou to wait for the follow-up.

After arriving in Shandong, the Zhangcun Daoist Department that set off this time also only needed to send 1,000 soldiers to follow the people back, and at the same time left 5,000 soldiers and people.

It's not ten thousand, it's four thousand.

Lao Zhu asked for 15,000 elite soldiers, and the remaining 11,000 soldiers will either follow the fourth batch of grain convoys or sail to the north alone in the next two decades or so, and it is expected that by the end of July, a large number of sea ships and people will be assembled in Laizhou.

The first day of June.

Off the coast of Mingzhou, navigation lighthouses everywhere once again lit up three fireworks.

According to the judgment of the meteorological team, the Yinghai Division issued another hurricane warning in the first year of Hongwu the day before yesterday, requiring all ships at sea to dock as soon as possible and reminding coastal residents to prepare for hurricanes.

Southwest of Dinghai, south bank of Yongjiang River.

Zhu Yuan got up in the morning, went to the camp of Yinghaiwei for half an hour as usual, and then set off here to check the construction of the resettlement houses for the displaced people in Shandong.

At the northern foot of Chenshan, in just over a month, more than 5,000 acres of land have been built into more than 5,000 yards of uniform size.

Zhu Yuan was not surprised.

As long as this nation stimulates productivity, a skyscraper a few hundred meters high will only take more than ten days. What's more, it is the concerted efforts of more than 20,000 people at the moment, and what is built is only a mud house.

After completing the construction of their own houses, the laborers from Shandong Province have begun to dig and kiln on another plot of land set aside nearby, preparing to build another batch of brick houses for the navy sergeants.

Because of the hurricane warning, there are more people here today, and under the guidance of craftsmen sent by the Yinghai Division, the thatched roof is compacted and reinforced with various wood and stone materials to prevent the thatched house from being damaged by the hurricane.

Seeing that all kinds of clothes were still rough and ragged in the summer, all kinds of people of all ages and children were busy, and occasionally people came to kowtow to him, Zhu Yuan wanted to leave.

I can't bear to look at it.

After walking roughly, he felt that his physical strength was a little exhausted, so Zhu Yuan got into the sedan chair.

Waiting for the sedan chair driver to start moving forward, Zhu Yuan lifted the curtain and said to Liu Lian, who had been accompanying him: "You take the time to plan, the thatched roof is too unstable, and when this gust of wind passes, start burning tiles, at least the roofs of all houses must be replaced with tiles." ”

Liu Lian did not object at all to the benefit of the people, and immediately nodded: "Hanlin, the lower officials have remembered it." ”

Zhu Yuan asked again: "Also, did you plan to temporarily allocate half of the house to house other soldiers and soldiers?" ”

"Drawn," Liu Lian pointed in one direction: "In the east." ”

"Let's take a look."

This is also what was explained after the hurricane warning was issued the day before yesterday.

Because of the hurricane, the community temporarily set aside half of the yard to house the many soldiers who still live in tents or cabins.

No way.

Like last time, the house is still not enough.

Zhu Yuan's initial idea was to receive a few people per household, and his subordinate officials reminded him that the displaced people in Shandong were all dragging their families, men, women, young and old, and if each household stuffed a few soldiers and husbands over, I was afraid that it would be inconvenient.

So it was changed to vacate half of the yard.

After checking again, the time came to noon.

I rushed to the bakery for a simple lunch, and inspected the warehouse and the riverside dock until the first hour of the unitary hour, that is, at five o'clock in the afternoon, before crossing the river and returning to the city.

Summer days are long.

Zhu Yuan returned to the Yinghai Envoy's mansion, and the sunset had just set on the eaves.

Dai Sanchun led Cui Shen, the director of the Instrument Bureau of Tai Hospital, who had been staying in Mingzhou, for a long time, and Cui Shen brought a newly built stone machine over.

Bang, grinding on the stone wheel also.

The stone machine, similar to the small lathe that later polished keys or car beads, was mainly used for cutting and polishing jade.

It all started a few days ago.

Freehand added a group of little girls in the inner house, Zhu Yuan gave a name, and casually ordered to cut some colored crystals to make an identity tag.

Freehand asked He Xuan to instruct Cui Shen.

Cui Shen had no opinion, but he accidentally ran into Liu Lian.

Liu Lian reprimanded He Xuan, found Zhu Yuan again, and continued to accuse himself of being an official, using public instruments for private purposes, damaging public fat and private, and not doing his job, and also said that the Instrument Bureau has been polishing and making all kinds of observation and measuring instruments day and night, and the manpower is not enough, and Zhu Yuan really shouldn't be like this.

The selfless officials of the Grand Duke cannot be provoked.

Can afford to hide.

Zhu Yuan asked people to find tools, planning to let the girls cut and polish by themselves.

Tools were found quickly.

There are two ways to cut crystal, line cutting, and also using a wire saw to solve jade sand, like sawing wood, cutting the crystal little by little.

The efficiency of wire cutting is very low.

Not to mention large crystals, even ordinary crystal stones with thick arms require a laborer to be busy for a day or two to cut.

There is another one, which is machine cutting.

However, due to the limitations of the grinding wheel, the cutting is only suitable for smaller pieces of crystal.

Not only that, but the grinding wheel itself is also troublesome to process in this era, and the cutting and grinding are worn, and they are also consumables. Therefore, craftsmen still use the most primitive and clumsy wire cutting to cut, and the stone machine is mainly used for grinding.

Only then did Zhu Yuan understand why the progress of the Machinery Bureau in making telescopes, surveying instruments, microscopes and other equipment was so slow.

In the case of telescope lenses, each process takes several days from cutting to polishing to final polishing, and a finished lens can take ten years to complete. Moreover, even if it is done, it may not be suitable for use, so it also needs to be reprocessed, and once the secondary processing is not completed, it will be directly reduced to scrap.

At the end of the day, it's still not very productive.

Zhu Yuan has always been very interested in improving productivity.

After roughly looking at the primitive stone structure of this era, Zhu Yuan had a series of thoughts.

The first is the grinding wheel.

The grinding wheels of this era were directly carved and polished with stones of various materials, which was also time-consuming and labor-intensive.

This is the first thing to change.

Moreover, it doesn't take much thought, as far as I can remember, I have seen all kinds of grinding wheels.

Zhu Yuan soon proposed a plan to artificially make grinding wheels with the jade sand used in wire cutting, which was later the commonplace grinding slice.

After many tests, the finished product was quickly baked.

The materials are fine sand, fish gelatin, and gauze.

Fine sand is commonly used by jade craftsmen to solve jade sand.

Jieyu sand is not a special kind of sand and gravel, but a fine sand used for 'Jieyu'.

How do you say that sentence, the stones of other mountains can attack jade.

The material of jade sand is the stone that can be used to attack jade, and there are mainly two kinds of common ones in this era, garnet and corundum.

Then there's the gelatin.

Local materials.

Finally, gauze plays a supporting and fixing role.

This was the opinion of a craftsman from the Instrument Bureau. Interesting, inspired by the soles of the lakes on the wall when the women were making shoes, Zhu Yuan also deliberately found and saw it, and then, vaguely, also collected some related memories.

Probably when women make shoes, they use the lake of rags on the wall with a noodle lake, and the dried hard embryo is cut and can be used to hold the soles.

The fabric, which was originally very soft, becomes very hard when it is made into a sole embryo.

Speaking of grinding wheels, if it is only fine sand and fish gelatin, made into a grinding wheel, it will be very brittle, and adding a layer of gauze in the middle is equivalent to adding a layer of bones.

The disadvantage is that this kind of grinding wheel cannot be fired in the kiln and can only be baked at low temperature.

Therefore, it is more time-consuming and the hardness is a little worse.

Zhu Yuan is already asking craftsmen to improve the process, making grinding wheel slices that are harder and more elastic and will not break easily through kiln firing.

For now, make do for the time being.

And then there's the slam machine.

In the traditional stone machine, the rotation during grinding is to pull the shaft repeatedly with a rope, and you can imagine how slow the rotation speed is.

Zhu Yuan's improvement method, the core is one, adding bearings.

Another result of bearing labor saving is actually to maximize the efficiency of manpower utilization.

Then, inspired by the bicycles of later generations, he made a pedal transmission model. Not a chain drive, of course, but a belt drive. Moreover, the bike is a small wheel with a big wheel, and the brand new stone machine, of course, is a big wheel with a small wheel in order to maximize the revs.

After the initial completion of the sample and put into use, what Cui Shen sent today is already the second generation.

Quite a simple makeover, from the first generation of single pedals, to double pedals.

Zhu Yuan saw the prototype and asked people to bring crystals for testing on the spot.

Two craftsmen stepped on the pedals, and another craftsman operated, loaded a grinding wheel only as thick as a few sheets of paper, and the craftsman stepped on the pedals, and the stone machine began to operate.

Crystals are delivered.

There is also an apprentice next to him, constantly pouring water on the crystal to cool down.

In the crowd watching, it was just a cup of tea, and a piece of crystal that was slightly thicker than his thumb was cut into two pieces, and Zhu Yuan had seen the previous one-man machine, and in comparison, the speed was much faster. Moreover, compared with the previous original stone machine, the cutting efficiency has increased by more than ten times.

It's simple.

Single-person slam machine, because only one person exerts force, the speed of the crystal is slightly faster, it will be stuck, or there will be a belt slippage or even directly break the slice and other failures.

The two-person stone machine, with an explanation that Zhu Yuan was more familiar with later, was that the power was doubled.

Although an additional operator was added, the previous problem no longer appeared. All in all, the efficiency is still greatly improved.

Zhu Yuan watched a demonstration, and after thinking about it, he asked people to find an iron rod, and when he operated it again, he quickly cut it into two sections.

After watching the demonstration, Zhu Yuan rightly ignored Liu Lian next to him, and directly ordered Cui Shen to send a brand-new two-person machine to himself tomorrow, only to find that Wu Zhen, the deputy governor of the navy, appeared here at some point, looking very interested.

After greeting him, Zhu Yuan asked Wu Zhen with a smile: "Do you think that I am not doing my job?" ”

Wu Zhen smiled and shook his head.

It's just that there are some objections in his expression.

Zhu Yuan personally walked over to check the two-person machine, and said to Wu Zhen: "I once told my ancestors a truth, the reason why we are the primates of all things, the key is to use tools. Since this is our strength, we should work tirelessly to create more and better tools to achieve the goal of continuously improving productivity. ”

In the first half, Wu Zhen and the others who were in the audience did not know that Zhu Yuan had already told them about economic terms such as productivity.

I have to agree.

Zhu Yuan continued: "At the moment of the great drought in Huaidong, the ancestor still asked me in the letter if there was a way, but I didn't. It's not that there isn't, but the productivity generated by the tools we can use today isn't enough to deal with it. Think about it, if we can create a large number of large-scale water pumping equipment to divert water from the Yangtze River or onshore wells to the fields, the drought will be solved. Actually, we have the corresponding equipment, all kinds of waterwheels, the problem is that no one has ever thought of making better waterwheels on a continuous basis, and the old-fashioned waterwheels, like the previous ones that were not efficient at all, are primitive and crude, so that we are still helpless against the drought. ”

After hearing this, Wu Zhen paused, retracted his expression, and arched his hand towards Zhu Yuan: "Hanlin, the cadres are taught." ”

Liu Lian also gave his hand: "Meng Zao is taught." ”

When the others saw the two Shangguan salutes, they followed suit.

Zhu Yuan just waved his hand, left the room in the outer courtyard, and planned to return to the inner house, but when he went out, he found that Wu Zhen followed.

Look ahead.

Wu Zhen's expression was slightly embarrassed, and he hesitated a little and said, "Hanlin, can you talk?" ”

Zhu Yuan nodded: "Go to my office." ”
