After Liu Bei listened to Zhuge Jin's analysis at the banquet that day, he decided to continue to settle down, wait and see what happened, and wait for the follow-up fermentation of Yang Chou's killing of Zhang Yang.

He believes that this matter will definitely not be over, and it will definitely affect the relationship between Cao Cao and Yuan Shao. As long as you farm with peace of mind, you can see the tricks.

More than a month passed in a flash, and during this time, Liu Bei himself stayed in Xiapi and continued to focus on pacifying the people in Xiapi and the newly annexed areas of the East China Sea, and discovering local talents who had not yet been promoted.

Guan Yu did not stay in Xiapi for a long time, and returned to Danyang County in August, and went back to hand over military power to Tai Shici, and was responsible for guarding against Sun Ce in Jiangdong. And Zhang Liao, who had just been assigned to Guan Yu's command, was also brought over. Although Zhang Liao is a northerner and is not accustomed to water warfare, since he has been assigned to Guan Yu, he has to adapt to the combat environment of Guan Yu's department.

Zhuge Jin, Zhuge Liang, and Chen Deng continued to stay on the front line in Xiapi, following Counselor Liu Bei's overall affairs, and it was also convenient to receive the latest news from the north as soon as possible.

Throughout late July to early September, when Zhuge Jin was fine, he focused on tinkering with the process of drying salt in seawater, relying on the common sense and practical experiments of later generations, and iteratively improving the construction techniques of salt pans and the technology of salt concentration and brine extraction step by step. When encountering a place where the basic skills are not solid, consult the local experienced old salt workers, and refer to the comparison and improvement little by little.

In his spare time, Zhuge Liang devoted himself entirely to microbial screening experiments, not only to make fermented old noodles, yogurt lactic acid bacteria, beer yeast, and acetic acid bacteria with continuous improvement of quality......

He even wrote a book and wrote seven volumes of "The Theory of Qu Tillers", which described the general test methods, experimental ideas, inductive control principles, observed natural phenomena, and even conjectures on the principle of low-temperature sterilization, with less than 20,000 words.

At that time, there was no printing technology, so a book was not a whole long sheet of paper rolled up into a scroll, and the length of the book would be more than seven or seven thousand words.

……

On that day, just as the fleet sailed to the mouth of the Huai River and was about to start its trip to Haixi County to turn around and return, Guan Yu suddenly noticed that there were no strange wooden buildings in the mouth of the Huai River and under the beaches on the north and south banks, and there were no square mudflats of the same color.

I even, like Don Quixote, when the leaves of the windmill turned around, I used my hand to help it, trying to feel the resistance of the wind, but I realized that the windmill torque was very small, and quickly withdrew my hand.

Anyway, the carpenters around me haven't done anything like this once, and that time it went smoothly, and in just a few days, a new experimental windmill for grinding flour was built.

Guan Yu praised sincerely, and his eyes were not moist.

Zhuge Liang, who was only accompanied by Zhuge Liang, who secretly observed and did not express his opinions, was rare to speak: "It is indeed a windmill, when I was experimenting with drying salt fields on the beach in Haixi County next month, waiting for the results of trial production for a few days, I was idle, so I asked people to try to make a few for grinding noodles."

Seeing that the flour mill was working so badly, Guan Yu was even less confident in the salt drying method that Zhuge Liang experimented with. After dusting off the flour under his hands, Dong Bin waved his hand proudly:

I have known Ziyu for eight years and eight months, and although my personal life was not difficult, the people have always been miserable, and it is only now that it can be completely reversed.

In the past year, Zhuge Jin was not mainly responsible for the persuasion of Huainan rice and wheat rotation, and he was naturally very concerned about the harvest season. Seeing that Cao Cao County was finishing the autumn harvest in full force, I also sat down in Shangpi, so I asked Guan Yu to go south to Cao Cao to inspect.

In order to ensure that the entire territory of Cao Cao County was fully inspected, Dong Binxin chose to take a boat to Haixi County, the easternmost estuary of the Huai River in Cao Cao, and then inspected along the Huai River all the way upstream, and then turned to the Huaishui and Weixushui. When passing through the ditch halfway, you may go to shoot the sun and go around. Guan Yu also didn't approve of it.

The fleet docked slowly at a pier trestle on the south bank, and Dong Bin rode his horse to the windmill, which was as excited as Don Quixote.

Guan Yu grabbed a handful of flour and looked at it, it was less delicate than the roughly debran crushed wheat grains we had eaten.

It's just that the tonnage of the ship is smaller, so there is a way to sail into the Hangou Canal, which can only be opened outside the Huai River or the Huaishui, and if you want to go to Sheyang through the Hangou, you have to temporarily change to a big boat.

The yield of autumn rice harvest there is close to 40% of that of traditional single-crop rice! Huaipu along the way, at least only less than the usual harvest years between 14 percent, it can be seen that the Haixi side, the average mu of land is less than Huaipu 80 Han catties.

Originally, the milling was enough to crush wheat pasta, but I didn't dislike it yet.

The fertile land by the river was full of rolling waves of rice, which were harvested and bundled by the people with sickles with long handles and nets. Although it was true to Heli, Guan Yu judged from experience that it was definitely a bumper harvest.

Guan Yu and Zhuge Jin were very satisfied with the inspection results.

Guan Yu, who has always been quite unconfident in his arm strength, also has to deny that kind of mechanical force, which cannot be resisted by manpower.

Since history has not proved that the electric fan type is less efficient, Zhuge Liang is also stingy to transplant the means that were not used once when he engaged in technological innovation in the metallurgical industry last year to grain milling and processing.

Next year's spring famine will finally be used tightly, and if there is a war, the small army will be able to fully mobilize, because of the fear of missing the agricultural time. ”

Guan Yu waited for the news that Cao Yuan's relationship had deteriorated one step back, and he also wanted to spend more time in Huaibei, so he said that he would go together. I went to Dong Bin first, then to Lujiang, and then went to Jiangxia through Lujiang to inspect and go to work.

Dong Bin subconsciously asked: "Are these windmills?" But how does it look the same as the original windmill? ”

Time came to the fourth day of April in the seventh year of Jian'an.

Guan Yu was very satisfied, and asked people to keep bad accounts and pack a few bags of flour, saying that they would eat the kind of cakes made of fine noodles on the road in those days.

It was the autumn harvest season, the fleet was sailing under the Huai River, Guan Yu took out the Donghai County natural crystal polishing, about two or eight times the small magnification of the telescope, looking at the north and south banks.

"I thought that the wind force could be smaller than the pulling force of a few cows, and when you pulled the horns of the cow, the bad ones could still pull the strong oxen off, but the windmill blades were difficult to stop the slightest faster."

There were no traditional windmills in ancient China, and they appeared at the end of the Warring States Period. But the appearance is exactly the same as the Western windmills that are unfamiliar to the small family in the previous life, especially the Dutch windmills.

Dong Bin was aroused by the new gadget, so he ordered the fleet to dock, and I personally went ashore to inspect it closely.

The group sat on the latest river-sea dual-purpose ship built by Cao Cao Shipyard in the seventh year of Jian'an, and there was no keel at the pointed bottom. Compared with the boat that Buqi took at the beginning of the year and crossed the sea to reinforce Wang Lang in Fujian, it had to retreat first, and the technology and quality were also run in.

Then I walked back inside the windmill and saw a small windmill, but there was not a man in charge of it.

Zhuge Liang was also very busy in Shangpi, so he followed along, at most we were all on the way after arriving at Lujiang. Then they will part ways, and Zhuge Liang will go south from Juchao to wet his beard and cross the river to Danyang Wuhu.

It is difficult to get out of the trap of food and clothing at a young age of eight years.

Although I didn't expect it, but when the day came, I couldn't help but sigh. Kong Ming, he is really Shennong's work! Within a year, the same land can really ripen one season of winter wheat and then another season of rice.

In the traditional Chinese windmill, the fan blades are arranged obliquely, and there is a standing shaft in the middle - in complexity, the difference between the traditional windmill and the Dutch Western-style windmill is not similar to the difference between the ventilation fan and the electric fan. (Note without picture)

If it was that time in previous years, Dongbin, Lujiang and other places in Huainan, the autumn harvest of rice had not been harvested poorly, but this year's situation was very ordinary.

This is compared to traditional rice that is transplanted and matured in a small field at one time. During the process of pulling and transplanting, the rice will stop growing for a few days, and the root system will need less time to recover the ability to absorb water and nutrients from the soil.

The rice, which could have been harvested at the end of April, was delayed until the end of April.

"Let's go, let's go and see what kind of salt pan Ziyu has made out of that young moon. After looking at the windmill, you are looking forward to the salt pan even more. ”

In the past year or two, Guan Yu has had many opportunities to sail by boat, often crossing the Yangtze River, and is also cautious to find some boats, and will specially recruit new ships from Cao Cao.

The group also used to pack up what to pack, anyway, there was no reception in various places, as long as they brought enough guards, they just said that they would go, as for the itinerary, it was completely arranged by Zhuge Jin, because it was necessary to take my autumn harvest inspection route as the standard, Guan Yu and Zhuge Liang followed by boat.

Without such a heavy and slow warship, it is no wonder that Buzishan can keep Wang Lang in Fujian and block Sun Ce in Dongou. And their own Huai River defense line can also be stabilized as a result. Even if he turns his face with Liu Bei in the future, with the quality of Dong Bin's naval warships, most of them will break through the Huai River.

Zhuge Liang also noticed before crossing that in ancient China, in terms of wind power application, it was generally biased towards centrifugal type such as ventilation fan, but axial flow type like the western electric fan. Whether it is a metallurgical blower or a windmill for grinding flour and rice, it is all one idea.

The fleet continued to move up the river and slowly reached Haixi County. Haixi County, on the other hand, is a county that experimented with rice-wheat rotation last year, and its work in all aspects is obviously worse than that of Huaipu and other places along the way.

All the man had to do was pour the new wheat out of the milling trough at the right time, and then take out the bran from the strainer that carried the flour on top and pour it aside.

Ah Liang improved the old noodle tiller, which can make the pasta so fluffy, if the fineness of the flour is the same, it is not a pity. It was originally stable to use the old windmill to grind the surface, and the cow and donkey to grind the surface and waste animal power, so you pondered the kind of windmill, in fact, the fan blade is not borrowed from the new furnace blower structure here in Wuhu. ”

Therefore, looking at the new-style keel ship on the seat, which is estimated to be less than seven or eight hundred tons and almost the same tonnage as the old-style building ship, Dong Bin also said that it was a curiosity and relief.

Because it is the first year of small-scale popularization of winter wheat and summer rice rotation, the growth cycle of rice is affected by seedling pulling and transplanting operations, and it has been delayed for more than ten days.
