Weapons, in this era is the sword and halberd, is particularly important to a country's army, a few days ago Liu Rong watched the entire production process of the barracks, found a lot of deficiencies, can also be called disadvantages.

First of all, although the whole barracks is a whole, in fact, it is based on workshops, a skilled blacksmith master, with a few apprentices, is a workshop, and each workshop may learn from each other or have a connection, but in fact, this connection is not so strong.

For example, the master of this workshop is more skilled, and the blade of the sword is thinner to meet the requirements, and the master is poorer, according to experience, he will make the blade thicker to meet the requirements.

There is also the production of spear heads and halberd heads, and Liu Rong also found that the size of the halberd heads produced by each workshop is also different.

Even, in the entire division barracks, he did not find the existence of a similar ruler.

A master is there to measure it visually or with the palm of his hand......

The disadvantage of this is that it cannot be mass-produced, a sword requires a matching wooden handle scabbard, and a halberd head must also have a suitable wooden handle to match, after any of the parts are damaged, it is very difficult to quickly find the matching parts, and the rest of the parts can only be taken back to the barracks for rematching.

If the size of these parts can be unified, these troubles will be saved, and the barracks only need to produce parts according to the size, just like the spare parts produced by each automobile company in the previous life for the cars in their own factories, the parts of the car are broken, and they only need to be retrieved from the manufacturer according to the specification name.

Compared with the parts of the car, the swords, guns and halberd accessories produced by the division barracks are much simpler, but if they are really built according to the unified style, it is a very big improvement in terms of material saving and building efficiency.

Therefore, Liu Rong's first suggestion was to make rulers and distribute them to each workshop so that they could be familiar with the use of rulers.

Later, Liu Rong drew the shape of a ruler, and after thinking about it, he drew the pattern of a tape measure and vernier caliper, and made annotations on the side.

Such as a tape measure, which can be made of silk. Vernier calipers, divided into upper and lower scales, how to calculate.

As for the current size, Liu Rong has not made any further modifications, this is too systematic and deep-rooted, and it is not easy to change.

Today's one foot, Liu Rong has probably been compared, which is about 24 centimeters in his previous life. One foot is ten inches, and one inch is about 2.4 centimeters in the previous life.

Think about the seven-foot man in ancient times, the height is about 1.7 meters, so as long as he is a normal adult man, he can call himself a seven-foot man.

Second, the size of the sword, gun and halberd is specified in detail, and the size is strictly followed.

Strictly according to the size of the building, perhaps in the early stage of the construction of a little slower, but after a certain period of time after the craftsmen are skilled, the impact is absolutely unprecedented, which is similar to the Qin Shi Huang at that time with the same track book and the same text.

Third, increase the number of forging and quenching.

The use of forging to reduce the carbon content of iron as much as possible, is the so-called 100 refining into steel, the performance of steel is much harder than iron.

Fourth, the improvement of quenching fluid.

The quenching solution is not necessarily all water, and a little salt or vegetable oil can be added to it, which can better achieve the quenching effect.

But Liu Rong didn't know the mystery in his previous life, he could only put forward such a general idea, and the specific effect still had to be summarized by the craftsmen in practice.

Finally, Liu Rong put forward the theory of assembly operation.

Human energy is limited, if a person focuses on only one thing for many years, it is easy to achieve the effect of mastery.

Think about it, if an iron smith is still thinking about how to make the handle of this knife after it is forged? What kind of wood should I choose? Undoubtedly, it was distracted and hurt.

Forging allows it to only do this job, which is boring, but it does achieve the effect of mastery.

This is the case with the assembly line in the previous life, and it has been tested in practice in the correct way, which has the effect of specialization in the industry.

As long as the dimensions are executed exactly according to the specifications, the hilt, scabbard, halberd handle, etc. can be done by someone who specializes in making them, and finally it is enough to assemble them together.

On weekdays, if the war is not tight, you can produce some easily damaged parts, such as sword blades, halberd handles, etc., and the rest can be completely recycled and reassembled. It saves both effort and money.

Four full volumes of silk silk were densely written, and Liu Rong tried his best to annotate in detail the feasible methods and the effects that would produce after each of the suggested methods.

There's no way, if you don't write clearly, you may be able to explain it clearly at the time, but it's still the people below who do things, so you can't let him explain every one.

If it can be solved at once, he definitely doesn't want to come twice. Even if it's a little troublesome now, it's worth it.

Therefore, for a whole afternoon, Liu Rong was in the hall, thinking, writing and painting!

The three empresses had already returned to the hall, and when they saw the emperor frowning and pondering, they did not dare to make a sound, and only quietly studied some ink for him when his ink was exhausted.

Sometimes, when the ink on the brush dried, Liu Rong also forgot to go to the inkstone to dip in ink, but just counted a few times on his tongue, and then wrote again, until the ink was light, and then went to the inkstone to dip in ink.

The three of them looked at each other.

It's just that there are some ideas, thinking about simplicity, but if you want to jump on paper, you have to spend some brain cells, and Liu Rong is exactly like this at the moment.

It wasn't until Liu Rong put down the pen in his hand, stretched out his arms, and got up for a lazy waist that the three of them suddenly felt relaxed.

The queen picked up a cup of tea and said, "Your Majesty, drink some moisturizing mouth!" ”

Liu Rong took it and drank it all.

Wang said, "Your Majesty, the concubine sent someone to my father, and my father replied, I will work overnight today, and all the tools will be delivered early tomorrow morning." ”

"Hmm!" Liu Rong looked at the sky, it was almost evening, and said, "Early tomorrow morning, you don't have to go to the backyard to serve, the preliminary process of the two kinds of paper is almost the same, according to the previous method, I ordered someone to chop the bamboo and cook it, and when I finished the activity, I can start the later process." ”

The three of them agreed.

Had dinner and was speechless all night.

The next day, Liu Rong, who had been practicing martial arts in the backyard for nearly an hour, vaguely heard a noise in front of him, and it was estimated that the queen had started.

Abandoning distractions, he continued his luck and began to try to see if he could combine luck with tai chi.

At first, the air flow in his body would collapse the moment his body moved.

But slowly, the air flow can last for a while after his body moves, which gives Liu Rong hope that his idea is still working.

Since it works, then you have to try, and at the moment, Liu Rong tried it over and over again.

Luck, Tai Chi got up, the breath collapsed, and it only lasted for a second.

Again, luck, momentum, this time the breath should be more than a second!

Hey? The pain in the body began to appear again, and it seems that it is working again.

Well, after a while, go to Zhao Yun and ask, what's going on?
