Pei Gai said to Xu Yu: "I heard that the Qin Dynasty made soldiers, and the name of the instrument was very strict. ~with~dream~small~say~щ~suimеng~lā that is, in the crossbow machine, the required parts are not less than twenty, if one of them is damaged, you can disassemble the same parts of the crossbow in time to replace it, and do not waste its use......"

Pei Gai's "instrument name" is the "name of the instrument" that was first seen in the "Lü's Spring and Autumn Period", that is, the manufacturer of the utensil should engrave his name on it, "to test its sincerity", so as to facilitate the implementation of the responsible person for product quality problems. As for the "very strict standards", and even the parts of the same kind of crossbow machine can be replaced with each other, it is not a record in ancient books, but a conclusion reached by later generations after studying the unearthed cultural relics of the Qin Dynasty, especially weapons.

It can be seen from this that the reason why Qin was able to annex the Six Kingdoms was not only because of the courage of the soldiers, "donating armor to the enemy, taking the head of the left and the right to take prisoners", but also because of the strong military industry - standardized production and strict liability system, is it possible that the weapons produced in this way are not sophisticated? It is said that this is all the credit of Qin Mo.

In fact, further back, the bronze smelting formula and 30 production design specifications and manufacturing process requirements were recorded in the "Zhou Li Examination Record", and the ancients had long understood the benefits of standardized production. But the problem is easier said than done, there was no big industry at that time, basically all of them were small family workshops, craftsmen are generations, oral tradition, to make qualified products all rely on experience, the understanding of specific parameters is very vague - most of the craftsmen are illiterate, how can it be possible to do it in accordance with the standard process? Therefore, only under the strong government and strict system of Qin, it is possible to form a national-level workshop that can standardize operations.

Since then, successive governments, compared with the strict structure of Qin, have regressed, and the understanding of standardized production is only on paper, even if the "name of the work" may not be able to be fully achieved, let alone in the troubled times, Xuzhou is just a new local force?

Pei Gai didn't pay much attention to this problem at first, although he gathered craftsmen from all over Xuzhou, and gathered together to produce weapons, farm tools, as well as large houses, vehicles, small utensils, jewelry and other products, but basically it still belongs to the craftsmen, just an aggregate of many small workshops, not a factory - the reason is also very simple, Pei Lingjun is busy with things, and he can't manage it at all.

It wasn't until Xu Ziyin entered the curtain that the situation changed slightly, but it did not fundamentally change the model of small workshop aggregation. Soon after Xu Yu entered the background, he followed Pei Gai's Northern Expedition, and along the way, the craftsmen in the army were mainly responsible for repairing damaged weapons, armor, tents, etc., and rarely made new things—how could there be a reason to cut wood, strike iron, and mix leather while marching? It wasn't until he settled in Chenggao that Pei Gai summoned Xu Yu to prepare for a fierce siege battle in the Henan region in the future, and asked him to try to make a cloud ladder.

Xu Yu successfully completed the task, but soon, Pei Gai discovered the shortcomings. Now he said to Xu Yu: "A few days ago, our army's ladder was either burned for the thieves to go up and down the ladder, or the thieves were set up to break the wheels, or the big stones were smashed to smash the front shield. Do you think so? ”

This truth is very simple, Xu Yu naturally understood it as soon as he heard it, and immediately arched his hand and said: "What the envoy said is the right theory, and Yu knows it, but ...... This is easier said than done......"

Pei Gai smiled: "I know that it is difficult, if it is not difficult, why don't you know how to use it?" ”

The benefits of standardized production are obvious, but it was difficult to do in ancient times. First of all, it is necessary to cooperate with the operation of a large workshop, and cannot be built by craftsmen in a dispersed manner - this is not a problem for Pei Gai, the artisan battalion was originally based on the art of war, with Xu Yu as the chief executive and chief designer, and it is easy to transform the work mode and form manual collaboration.

The most important thing is the problem of weights and measures, there are few standard measurement tools in these years, and the material is not up to standard, because of the problems of thermal expansion and contraction, resulting in a large difference between the four times, so the parts are universal, the Qin Dynasty can barely do it, this year because of the lack of relevant awareness, coupled with the troubled times, the technology has regressed.

Of course, Pei Gai couldn't come up with any advanced weights and measures tools, so he had to guide Xu Yu to see if he could try to manufacture the rest of the parts according to the size of a single part, so that the craftsmen could form an assembly line operation, which might reduce the efficiency and slow down at the beginning, but after getting used to it, it would be good, and it would also be beneficial to the manufacture and repair of weapons.

He then placed a large order for twelve ladders, ten artillery trucks, and five crash cars.

The ladder is still the same, and according to Xu Yu's new idea, some of the joints are reinforced with iron nails - no longer only tenon-jointed. The cannon car is a new shape, Pei should take out the drawing to show Xu Yu, Xu Yu took a cursory look, and couldn't help but be overjoyed: "This is not the 'thunderbolt car' made by Wei Wu?!" ”

During the Battle of Guandu, it is said that Cao Cao once improved the trebuchet and made a "thunderbolt" to deal with Yuan's plan to set up a fortress and release arrows. It is said that the biggest advantage of this kind of "thunderbolt" is that there are wheels under the machine, which is convenient for movement, and second, the cannon can rotate 360 degrees, pointing where to hit.

Pei Gai smiled: "If you add wheels and movable guns, what's so difficult, why can't you care?" "If you know these two advantages, can't you still make them, why bother with me to redraw them for you?

The most important and epoch-making improvement point of the artillery cart painted by Pei Gai is to change the manpower stone throwing to the counterweight stone throwing, that is, the short end of the cannon rod is no longer tied to countless long ropes, and when the time comes, the soldiers will pull together to throw the cannon stone into a distance, and change it into a wooden bucket that can be weighted. When fighting, the long end of the cannon rod is first dragged down by the soldiers and force, tied with ropes, and placed into the throwing stones, and then as long as the rope is cut, the short head naturally hangs down because of the action of the heavy objects in the wooden bucket, and the long end is raised, and the cannon stone can be thrown.

In fact, this is quite similar to the "Xiangyang cannon" in the Song and Yuan dynasties. The advantage of the old cannon cart was that it could theoretically be built very large, and as long as there were enough soldiers pulling the ropes, the cannon could be sent out as much as it wanted; The weakness is that it is difficult to cooperate perfectly with the pulling force of multiple people, so the accuracy is very poor. Pei Gai designed the new artillery truck mainly to enhance accuracy.

As for the collision, it is very simple, there is no new idea, it is to put the siege vertebrae on the car, which is convenient to push, and at the same time, put on the "Jie" shaped wooden canopy, covered with leather and wet thatch, which can avoid being broken by throwing stones or arson on the city to a certain extent.

Xu Yu carefully looked at the drawings drawn by Pei Cai - in fact, it was very crude, it was just a schematic diagram, and it was impossible to start manufacturing based on it, but the so-called design drawings in these years were probably at this level, and I didn't see Pei Zhijun's shortcomings - there were a lot of problems when I picked them. But he didn't ask—because he knew that if he asked, he might not be able to get an answer, and maybe the Shangguan would be ashamed—he felt that his level was enough to refine and improve, so he nodded and answered.

——————————

The ten-day period has not arrived, and the siege equipment is still being intensified, and the Jin army from all walks of life has gathered under the Yanshi city - since Liu Cang has escaped, and Liu Fu is trapped to defend Yanshi, and Liu Ya is trapped to defend Ping County, there is no longer a mobile force of the Hu army in the Luoyang Basin that can threaten the Jin army, and there is no need to arrange too many men and horses to defend in Chenggao, Wushi and other places. On the Xuzhou side, Xie Feng and Wang Gong led the East Route Army to arrive smoothly, and the "Pengshan Left Battalion" that conquered Chen Chuan and Pei Wei with the soldiers and horses left behind in Chenggao also returned to Pei Gai's side.

Pei Gaijia Wang Gong said that he had surrendered to Cao Wei, and formally sent a letter to Chang'an, not Jiankang, asking for a pardon for his previous sins of rebellion, and to be accepted under his command as a record.

followed Xie Feng and Wang Gong over, and naturally there was also Su Jun and Su Zigao, who claimed to be the county commander. To Pei Gai's surprise, this future "traitor" is very handsome, not like a general with troops, but like a scribe, and his export is full of chapters, and his writing is elegant - although he is not very beautiful, and his physique is healthy, he actually has the demeanor of Wei Wei Shubao.

Su Jun's posture was very low, and he called "Ming Gong" very affectionately, which really made it difficult for Pei Cai to have a bad feeling for him. Thinking about it carefully, it seems that it is indeed recorded in the history books that Su Zigao is "less of a scholar and talented to learn...... So in that case, don't let them be generals, but take them with you as a clerk.

When it came to his plan, although Su Jun was not very happy, he didn't show it on his face, but just bowed his head and pleaded: "If it is a peaceful world, Jun will voluntarily belong to the Ming Dynasty and be a small official." However, now Hu Lu is raging, the society is replaced, Jun is determined to recover, and Ya is unwilling to work for a long time. Although Jun is a cold man, he has no talent, and it is difficult to work on Dingyuan, but he also has the ambition to write - he also hopes that Ming Gong will be fair, Jun Ming will feel five inside, and he should serve his life wholeheartedly. ”

Pei Cai tapped his finger on the bookcase, and said in his heart that there are actually a lot of generals under me, and what is lacking is administrative talent......

"In today's scene, there is a lack of pen like a rafter, if you apply, the main book and the history of Gong Cao are not rare; And if you join the army, it is only a hundred people - and think about it. ”

Pei Cai deliberately accentuated the word "hire". You must know that the Jin system basically continued the Han and Wei systems, and the state and county adjutants, or the generals and shogunate officials, except for important positions such as the state commander and the military commander Shi and Sima, which required the approval of the imperial court, were generally recruited by the chief officials themselves, which was a bit like the master of later generations. In this regard, the relationship between the subordinate officials and the chief official belongs to a temporary employment relationship similar to that of Xixi and Dongweng, and if they are together, they will stay, and if they do not, they will go, which is quite free, and it also retains the dignity of the scholar completely. And the general is different from the generals under his command, especially in the ranks of warlords in troubled times, which are only one step away from the master and servant, and there is almost no dignity at all.

- Of course, if you completely treat your soldiers as slaves, then mutinies and even rebellions will definitely be common.

Moreover, if Pei should hire Su Jun as the chief secretary of the shogunate or the history of Gong Cao, the rank is 600 stones, which is about the same level as the Ye County Order he originally profeessed; And if he is only used as a general of 100 people, that is, the captain - Su Jun's grade is too low, and Hedong is too shou Guo Mo to be the battalion governor, it is impossible for him to lead a battalion by himself - it is obviously a demotion.

That's why Pei Caicai said, you think about it carefully.

Su Jun arched his hand and said: "Jun Chu returned to the Ming Dynasty, he has not made an inch, and he should be used as a junior and secondary school in the battalion, how dare he have extravagant hopes?" Hundreds of people will also have the opportunity to make meritorious contributions, and they are willing to do it. ”

Pei Caixin said that this kid really knows each other! Or does it also show that he is cunning enough? Well, if you wish, you will put Su Jun under Xie Feng's command to obey his orders - whether it is a donkey or a horse, pull it out for a walk first, and as for whether it will be difficult to control in the future, let's talk about it then.

At this time, the battalion governors of the Xuzhou Army were left with only one battalion of regular soldiers and two thousand auxiliary soldiers led by Lu Yan to be stationed on the south side of Pingxian County to monitor Liu Ya; Lu He led the "Wulin Left Battalion" and a new battalion to block the Mengjin Ferry, and the rest had already converged.

The Xuzhou army was no less than 20,000, and the Yuzhou army was around 40,000, besieging Yanshi City like an iron bucket.

On this day, Lu He suddenly sent a message, saying that he had just received news from Guo Mo - "General Guo heard the movements of the Hu army in Hanoi and wanted to return from the south, and he came to see the envoy in person." ”

Pei Caixin said what is the big deal, you have to come and tell me in person, and you don't want to send someone to send a letter first? Could it be ...... Liu Cong really hung up, or died of serious illness and was bedridden, and was about to hang up? waited patiently for a whole day, and it was not until late in the evening that Guo Sidao began to enter the camp quickly, and also brought back a general named Beigong Chun.
