For trebuchets Liu Lan desperately hoped that the Ordnance Factory could develop a thunderbolt similar to Cao Jun, but he also knew that it was very difficult, but no matter how difficult it was, it could not be an excuse for not being able to develop it.

To be honest, the scale of the ordnance factory has continued to expand in recent years, although because some of the equipment produced and sold can provide them with all the sources of funds, and Ou Yejian does not need to pay any taxes to him at all, and even Liu Lan will take out a part of the treasury to reward innovative craftsmen, which has caused many people to be dissatisfied in the cabinet.

Especially in the current situation of tight treasury, not to mention the tea sets, wine utensils and pottery sold by the ordnance factory, the agricultural tools alone are an astronomical amount, and such a large piece of fat is almost comparable to salt and iron, not to mention that the cabinet is eager to be directly assigned to the general's mansion, and even the states and counties want to get a piece of the pie.

What is the problem with the ordnance factory, but they want them to contribute and contribute, this person has a little bit of a careful mind that hates people and laughs at people, whether it is openly or secretly, although Liu Lan has been pressing, after all, Ou Yejian, an old friend, he still trusts him very much.

But after the emergence of the thunderbolt, Liu Lan felt that he could not let the ordnance factory dominate in such a way, no matter what a good system was, it was adapted to the special period at that time at the beginning, but with the development of time, it must have become out of place, just like Liu Lan entered Xianyang in the early Han Dynasty, and the three chapters of the law could govern Guanxi, but after seizing the world, Xiao He had to make Han laws in accordance with the Qin legal system to meet the social needs of the time.

And now the ordnance factory is too bloated and complex, some factories should also be separated, just like the factory that makes tea sets and wine sets, this kind of ceramic supplies are made of clay to make utensils, so it can be completely stripped from the ordnance factory, as for whether this kind of workshop is directly transferred to the civil or official after the stripping is also set up without thinking too much, it can be parallel, this matter Liu Lan and the plan to be stripped by the states and counties are directly responsible, and the Ministry of Industry is responsible for it.

As for the agricultural tools, they should also be stripped off, and the future ordnance factory will only be responsible for military equipment, so that Ou Yejian can also deal with the affairs of the ordnance factory wholeheartedly, without being distracted by other trivial matters.

As for the civilian agricultural implements, in fact, some private workshops can make them, and if they are separated, the workers who have mastered these skills can either set up their own workshops or continue to work in the workshops set up by the Ministry of Works. Although Liu Lan also knew that this matter would take some time, and the people in the Ministry of Industry did not necessarily have experience in business, and these people were all officials before the Han Dynasty, and most of them were in charge of salt and iron.

It is not known whether the workshop in charge of such officials will be like the situation of selling salt, Liu Lan is too aware of the situation of salt and iron, because the state is responsible, and the people cannot buy goods of too high quality with money, and this kind of government-run workshop may be the same.

And Liu Lan has this kind of consideration, so he allows the government and private offices to appear together, so that he can completely force the equipment produced by the Ministry of Industry to continuously improve the quality.

Of course, Liu Lan doesn't know if there is a mistake in such a decision, but at least now this is the best way for him to deal with it, as for what problems will occur, as long as they can solve it quickly afterwards, after all, they are all crossing the river by feeling the stones, and there is no experience of any predecessors to learn from, there may be many detours, but as long as they do not stand still, they will be able to succeed one day.

However, Liu Lan will not be too worried about the affairs of the Ministry of Industry, because he already has a more suitable candidate, that is, Shi Yi, although he has shown great talent in the military, but when he proposed to strip the armory factory building, Shi Yi showed great interest, Liu Lan knew that he was a county official in Beihai in his early years, and the county officials would be involved in this kind of thing to some extent, so he was no stranger, and even had great interest in these ideas proposed by Liu Lan.

The affairs of the Ministry of Industry, in the early days, were under the auspices of Chen Jiao, and with Chen Jiao to Guangling, after dealing with the matter of Guangling, it is bound to go to Xuzhou for a long history, so the Ministry of Industry is just a window in this period, although the Ministry of Industry temporarily handles official business, but don't forget that Liu Lan has already complained about this kind of official, or the previous work attitude, salt and iron let them make the people complain, and then the farm tools will appear what kind of fake and shoddy products, it is not surprising.

Of course, Liu Lan set up the Ministry of Industry in the county to supervise at the same time as his general's office, so this set of procedures for supervising the ordnance factory can still be used.

This matter Liu Lan asked Shi Yi to take his own handwritten documents to Zhang Zhao and let him be responsible for supervising it, but Yi was personally responsible for it after taking office, and he flew a pigeon to pass on the book to Ou Yejian, so that he could cooperate, and the future ordnance factory was only responsible for the production of weapons and research and development, and several major production plants whether it was bows, crossbows, swords, guns, spears, armor, helmets, or even trebuchets and bed crossbows could really be refined, arrows are arrows, bows and arrows are bows and arrows, and this efficiency is naturally greatly increased.

At the same time, the R&D department can gather those experienced masters and let them conduct experiments, he believes that in this way, not to mention trebuchets, even gunpowder and firearms will be developed in the near future.

In fact, although Ou Yejian is a famous craftsman in the world, there is one thing that must be said, that is, his vision is also stuck in this era, even if he sees farther than ordinary people, but it is impossible for him to truly innovate, at least he will never think of turning cold weapons into hot weapons.

At first, his innovation was like a head-on confrontation between the heavy cavalry and the trapped camp, and he was at a disadvantage, and his so-called innovation was actually constantly improving the armor, making the heavy armor of the guards thicker and more defensive, and you let him think of other ways, at most, what to say to make the weapon sharper and break through the thick armor of the trapped camp, but are these the answers that Liu Lan wants?

No, because this is not the direction of development he wants to see, what he hopes to see is that Ou Yejian can jump out of this fixed thinking and look at the problem from the perspective of God, but he finally found that in fact, even he can't avoid this problem, that is, let alone gunpowder now, even better steel can't be made.

This is Liu Lan's biggest headache now, and raising the temperature of the steelmaking furnace is actually the most urgent task now, only the quality of steel continues to improve, then when Liu Lan puts forward some wonderful ideas, it can be possible to be developed.

And any of his ideas now are just empty talk.

In addition to these, Liu Lan's urgent hope now is the catapult, which will bring great convenience to the siege and defense of the city in the future, if it has not been successfully developed, it will make them very passive, once the technology of the thunderbolt is mastered by Yuan Shao, the consequences will be even more unimaginable.

Even if Cao Cao didn't leak it, Liu Lan didn't want to see a situation like Pei County again, the troops were trapped in Pei County, and the soldiers defending the city were always under the attack of the enemy's boulders, in this case, the best way was to abandon the city and flee, but it didn't matter if he abandoned a Pei County, but when Cao Cao arrived at Xuzhou City, Peng City, did he also want to abandon the city and flee, wouldn't that be equivalent to giving up the entire Xuzhou?

And now the ordnance factory is too bloated and complex, some factories should also be separated, just like the factory that makes tea sets and wine sets, this kind of ceramic supplies are made of clay to make utensils, so it can be completely stripped from the ordnance factory, as for whether this kind of workshop is directly transferred to the civil or official after the stripping is also set up without thinking too much, it can be parallel, this matter Liu Lan and the plan to be stripped by the states and counties are directly responsible, and the Ministry of Industry is responsible for it.
