After inspecting Luoyang New District, Li Su thought in his mind that the place would have to level and divide all the land and complete the dirt roads, which would probably be after the slack season this summer.

To make good drainage channels and other supporting facilities, and to simply circle the low rammed earth city walls, it is estimated that even the slack time of winter farming is needed.

So starting to build a house on a large scale is probably going to happen next year. Fortunately, he was not in a hurry and slowly got into the infrastructure team and accumulated technical experience. It was also quite good.

Moreover, once these technologies are put into large-scale application, they will definitely not escape the fate of technology spread.

After all, craftsmen in construction engineering cannot be managed centrally like craftsmen in workshops. These talents are migrant workers, and you can't hinder the project site.

Fortunately, neither Yuan Shao nor Cao Cao had any chance to build a large-scale project, so Li Su has started to lit this kind of technology tree in the past two years, and even if it spreads, Yuan Shao would have no life to go to the flower.

Even if Cao Cao has a few years to live, he will not have any particularly good application scenarios. Even if he spreads over and Cao Cao forced his construction, Liu Bei could still regard it as building for him.

These large-scale projects have a long return cycle. No matter how fast the project is, it cannot recover the investment in ten or eight years. Cao Cao spent money on his capital and was destroyed before he could make it back. Wouldn't it be wonderful?

So, if you want to learn, learn. Li Su doesn’t care. After learning well, how to build a new city and dig a canal, just treat it as a contribution to the Han Dynasty after reunification.

After inspecting Luoyang New District, Li Su embarked on the road to Wancheng south for a few days and continued his inspection after the busy farming season in this spring.

...

In late March, Li Su first arrived in Wancheng. Gao Shun, the defensive commander of Jingzhou, personally went out to the city for dozens of miles to greet him, and also brought a large number of troops, mainly recruits recruited in the past two years, for Li Su to review and see his achievements in the expansion of the army.

Liu Bei's camp expanded its army by 80,000 last year, of which 40,000 were recruited from farmers' families, and 40,000 were transformed prisoners of war.

This year, the army was expanded by 100,000, and there were also 70,000 prisoners of war. The newly recruited local good families was reduced to 30,000. In addition, an additional part of the difference was raised to make up for last year's war losses.

It is the end of March now. Apart from the 30,000 good families this year, only 10,000 yuan has been collected, and there is still a gap of 20,000 yuan. The prisoners of war have been in place long ago and have begun to undergo hard labor reform in winter.

Now that they have almost become angry, they feel that Liu Bei's service and living conditions are indeed better than those of Yuan Shao and Sun Quan. People's hearts gradually gathered and they officially formed an army.

Therefore, the total force of the mobile troops that Liu Bei's camp can currently be used for expeditions on foreign expeditions (that is, the second-tier city-defense militia that can only defend the inside line) has expanded to about 480,000 people, and by the summer, it can all expand the troops to reach 500,000.

Of course, among the 500,000 people, 200,000 have served less than two years, of which 100,000 are less than one year, and the level of military training is relatively low.

The veterans who took the elite route of war always had about 300,000.

There are also 100,000 soldiers in these 300,000 miles. They were a soldier in more than five years. They fought all the way from Yizhou before the Northern Expedition to Guanzhong. They fought with the Xiliang army in life and death. They were used to the blood of life and death, and their psychological qualities were also very strong.

The remaining 200,000 have three to four years of combat experience, and the overall pace of expansion has always been very steady.

In fact, Li Su didn’t have much to inspect the details of the military expansion. He didn’t understand these ancient military discipline and tactical training, so he just wanted to leave it to professionals to do professional things.

Moreover, with the current military technology optimization of Liu Bei's camp, soldiers do not need the refinement of tactics and war disciplines. Those elite troops that require martial arts, such as the trap camp, can be directly transferred from veterans who have long-term warfare.

As long as the recruits are equipped with a quadrangle gun forged with steel, super long spear rod, array stabbing, or equipped with a divine arm crossbow, aiming and shooting rhythmically, or following instructions to cover shooting, they do not need much martial arts and can be practiced in a few months.

Therefore, the key to training is to keep soldiers strong morale, have seen blood, are not afraid to fight, and maintain a disciplined state of strict formation and unchaotic no matter what the situation is facing.

As for whether the military discipline is good or not, this entry-level indicator, a layman like Li Su can also see that at least Gao Shun's subordinates are more than 100,000, which is obviously different from the original peasant state, or the old troops under Yuan Shao and Sun Ce.

It seems that the troops are moving very neatly, and they can basically implement orders. Even if there are some movements that are more chaotic, they can do it at least in terms of obeying orders.

More importantly, these new army looks very clean and have a different temperament and aura, which is not comparable to the old army.

Before Li Su came, he also heard reports from Zhuge Liang and Huang Yueying, and knew that this was related to the "sewing machine" that Huang Yueying had invented before last winter.

Li Su has been urging this innovation in the field of garment technology last year. This job was not important in the past few years, mainly because there was no surplus of textiles.

In the past few years, the entire industrial chain of a set of clothes was completed, and the labor intensity of the spinning and silk weaving links was much more laborious than the final tailor.

Suppose a set of clothes is turned from cotton or silk to a finished product, and it takes a female worker fifty hours to manufacture the fabric in the front, and the tailor only counts the labor force for more than ten hours. Therefore, the main contradiction lies in the front, the tailor is slower, not standardized, and there is no big problem.

However, as the silk fabric industry uses new brocade weaving machines in large quantities, especially in the past three years, even cotton cloth has begun to use new wide-width looms and hydraulic spinning. In areas under Liu Bei's jurisdiction with new corridor technology, the production efficiency of the textile industry has generally increased by two to three times.

In this case, perhaps the labor time for a set of clothes is reduced from fifty hours to twenty hours, and it seems more troublesome to make tailors after another thirteen or fourteen hours.

The initial sewing machinery was not difficult to invent, so as early as last year, when Li Su destroyed Sun Quan's Jiangdong land, Huang Yueying had already made a hand-crank sewing machine, and later tried to produce a foot-pedal type. However, the testing, promotion and mass production of the machine took time, so it was only last winter that it was put into commercial use on a large scale.

Hand-crank sewing machines are not difficult to build, and they do not involve the industrial revolution. The key is to make the mechanism of hook needles for each circle of the wheel with seams precisely. Let me give you a general idea. Craftsmen can always try to adjust the hook structure themselves.

In theory, foot-pedal sewing machines are more advanced than hand-crank sewing machines. Hand-cranking basically achieves at most about five times the efficiency of hand-sewing needles for women, and cannot be increased faster. If the foot-pedal is done well, it can be at least eight to ten times faster than hand-sewing needles or even faster.

However, after seeing what Huang Yueying invented, Li Su chose to promote the hand-cranking style, which is mainly made by Huang Yueying. It is very different from what he has seen in his impression, and the efficiency and stability are not very good.

This is easier for people born in the 1980s to understand later generations. Friends born in the 1980s should have seen a foot-pedal sewing machine at home when they were young. The older generation would be called "ribbons". The power of the thing to drive the sewing wheel is provided by a reciprocating pedal.

To put it bluntly, this practice requires a mechanism that "changes reciprocating movement into circular movement", such as the crankshaft. It also requires a certain amount of experience. The first few rounds must be stopped at a position that is more suitable for force to be easier to step on.

Sometimes when the sewing needle is not in good condition, the older generation of parents must shake the wheels on the counter before stepping on the sewing machine to give the initial velocity inertia.

However, Li Su has been engaged in industry for more than eight years, but has not put in much effort on the crankshaft that "changes reciprocating motion into circular motion". The crankshaft accuracy and efficiency he has made are not very good.

This is also because Li Su does not need a steam engine, so he does not need a precision crankshaft. The birth of the precision crankshaft was originally intended to turn the piston movement of the steam engine back and forth into the circular motion of the flywheel. Most of the work steps require circumferential work. This thing had to be built during the steam engine revolution.

But in many cases, water trucks do work, in fact, there is no trouble of changing the circle and turning the circle. Therefore, it is not surprising that the crankshaft accuracy and rent reduction are not good enough.

Even if the water truck forging hammers had to use "hammer head to reciprocate", it was not done by the crankshaft.

Instead, relying on the tooth chain and steering wheel, the lifting steering wheel that controls the hammer handle can no longer be stuck after turning to a certain angle, causing the hammer handle to rise naturally and the hammer head to fall naturally. The whole process actually relies on the two links of gravity potential energy storage - free fall to complete the work.

Under such an industrial foundation, the foot-pedal sewing machine that Huang Yueying first built was not what Li Su imagined, when he was a child in his previous life, but was stomped around the two pedals like a bicycle, so that they could be driven to the sewing wheel through the pulley.

The lower part of the entire sewing machine is like a fixed-type dynamic bicycle for fitness. When working, the female worker's lower body will shake left and right as she stepped on the wheels. The upper body will work very unstable and will easily be pricked. So Li Su told not to promote this kind of sewing machine first, and would rather use it by hand.

In which year will the problem of the female sewing worker shaking her upper body when she stepped on her feet, and in which year will she promote the foot-pedal style?

This requires Zhuge Liang to sort out with his wife after he is idle and focus on solving the problems of crankshaft accuracy and drag reduction.

But no matter what, after temporarily mass-producing the most reliable and stable hand-crank sewing machine, even if the efficiency improvement ratio is not so exaggerated, it will be at least five times the speed increase.

Originally, a female worker could tailor a military uniform for fourteen hours, but now she only had three hours. Even if she didn't stay up late and worked overtime and only worked during the day, she could make at least two pieces of clothes a day. If it was sunny in summer, she would work as soon as the sun was dawn and could do half more pieces.

Of course, the speed of making clothes can be improved not only by accelerating the sewing process, but also by acquiring the cutting process.

Li Su originally thought that this link was not too time-consuming and did not deliberately arrange tasks. However, when Huang Yueying was working on it, she also wanted to create a hydraulically driven dress cut by the "hydraulic circular saw cutting wood" for the construction of Luoyang New District.

But soon discovered that the cloth was much softer than wood and was easily deformed in front of the serrated wafer, so it was impossible to cut. Finally, after a while, it was changed to two rough steel wires that were pulled opposite each other, which could act as scissors.

Although the cutting speed of the prototype machine is not fast, fortunately, it can cut a thick stack of fabrics at one time. On the one hand, this can save the trouble of drawing lines on each layer of fabric to confirm the cutting trajectory, and also ensure that the size of each part of the same batch of fabrics is consistent.

Therefore, although this machine did not increase much production speed in the early stages, at least the defective rate of finished products was reduced a little, and the shape of military uniforms of the same batch of sizes was the same. It was not helpful for small-scale clothing for civilian families, but for large-scale mass production of military uniforms in the army, uniforms were still quite good.

After all these measures were used, the military appearance that Li Su saw during his inspection today was clean. Except for the different specifications of the clothes worn by more than 100,000 people, the other styles of clothes are the same, and they look very neat and majestic.

When Li Su watched costume films in later generations, he didn't think there was any problem with this kind of scene. That was because the scenes of filming and TV filming in later generations, the clothing props were produced on a large scale on industrial scale, so he was used to "the clothes of the soldier are the same."

But in fact, since the time traveled through time to the past decade, Li Su has been a long battle formation and has seen various troops. In fact, he has never seen troops with highly unified military uniform specifications.

Even if tens of thousands of elite troops stand there, they all look scattered. No matter how strict the military discipline is, the same is true for the troops. The helmets and armors are slightly different in size and shape, which is an inevitable defect of handicraft processing.

Now after the rectification of this new technology, we have finally achieved a scene where the specifications of the military uniform of the soldiers are strictly unified.

It took Li Su many years to see the basic operations that were easily implemented on the set of later generations of magical dramas.

Behind the neat military appearance, at least tens of thousands of peasant women had saved half a year of working time. These saved labor were also a supplement to Li Su's increase in the collection of local corvee labor in Nanyang. At least it reduced other burdens for the people, and the complaints of the people when they were conquered were not so fierce.

...

After inspecting the military appearance of the troops, Li Su praised Gao Shun's work very much, encouraged her a lot, and briefly explained to Gao Shun: It is certainly a great achievement to be responsible for killing the enemy on the front battlefield.

However, the middle defense line can be stabilized in the rear, and the troops can continuously form combat effectiveness. This contribution is no less than the battle to seize the city. The key is that Gao Shun's work can be summarized and formed experience and promoted, which is a merit.

In the future, even if you are not a local defense envoy, you can return to the court to serve in the Ministry of War, and also have the future of civil servants and military officers.

Gao Shun was naturally grateful for Sikong's encouragement, and said that he would continue to work hard and would never slack off just because he had not been on the battlefield in recent years.

Afterwards, he arranged for chariots and horses to escort Li Su to Bowang County and inspect the work on the canal construction site.
