Liu Lan came to Langya in person, if it wasn't for Hou Qian, he wouldn't have this opportunity, and now he has the opportunity to come to Langya to inspect in person, before arriving at the city tower, he found that Langya City has really changed dramatically from his previous arrival, of course, the most different point is that the bed crossbow produced by the ordnance factory, even he has not seen it.

In fact, some of today's weapons, Liu Lan, who has rarely arrived on the front line of the battlefield, really doesn't know much, not to mention that this is still the latest bed crossbow, which is directly transported to Langya after being produced, it can be said that there is no second batch of such bed crossbows in Xuzhou, and the new bed crossbow is very different from the bed crossbow produced in the mining period and the Liaodong period.

In the past, the bed crossbow was large and inconvenient to move, although the lethality was huge, but his condition was almost no different from the previous crossbow arrows, so after the crossbow arrows were developed portably, the bed crossbow was almost also innovated under such improvements, and it was still under the same lethality.

For the production of this kind of weapons, Liu Lan has not asked much now, it is completely handled by the cabinet, although what to produce, what kind of ordnance is preferred in Ouyejian, but the distribution after production is decided by the cabinet, and with the convenience of the bed crossbow, the introduction is faster, everything becomes easier, looking at the bed crossbow above the city tower, Liu Lan is quite satisfied, of course, this is completely an attitude in front of everyone, after all, it is from the next generation, knowing that firearms are the real big killers, So the weapons of the cold weapon era are really not what he values very much.

But everything needs to be developed slowly to be manufactured, not to mention firearms now, even gunpowder is in the initial stage, although Liu Lan also knows that one nitrate, two sulfur and three charcoal, but it is still a long stage to really make gunpowder mass-produced, and even to be used, not to mention that even if firearms come out, whether the iron tools produced can be manufactured into firearms is still a question.

Therefore, for firearms, Liu Lan still let them slow down in research and development, although the effect is not too obvious, but he believes that it will not be long before there will be a qualitative leap.

Liu Lan asked east and west above the city tower, and asked all the equipment to defend the city, although now these defenders are all Qingzhou army, almost no Liu Lan has been seen, it may be accompanied by Xu Fang Zangba and even Guan Yu and Zhang Fei, and they are all condescending to the back, respectful, how terrifying is this person's identity, when everyone is questioned, they all answer with sincere fear, afraid of saying the wrong thing and causing trouble.

These people's answers are cautious, and can even be described as watertight, especially for the bed crossbow, although it is the latest bed crossbow, but he is still the same as the previous bed crossbow, although it is convenient to quote, although the killing god is very large, but the range has not changed, and even can not be like a crossbow arrow to draw five arrows at a time, if the bed crossbow can also shoot arrows like a crossbow, although Liu Lan does not dare to guarantee that the city will not be breached, but the deterrent and killing effect on the enemy army must be unprecedented.

And this is actually what Liu Lan is not satisfied with, but he also understands that some things cannot be rushed, technological innovation is based on the accumulation of the original technology and exploration and discovery, and only after forming a set of scientific theories can it be continuously improved and surpassed, just like the crossbow machine shoots one arrow at a time, and now shoots five arrows at a time, which is realized in such a slow process.

And among them, because of taking shortcuts, many ideas were put forward by Liu Lan, but the more this is the case, the more Liu Lan has to rely on them to discover and explore, after all, he knows very limited, there are specializations in the art industry, and there are some things, he knows them but doesn't know why, so he told Ou Yejian, so how to produce them next and continuously improve them is not something that Liu Lan can decide, and these craftsmen are needed to improve and innovate through continuous efforts.

For the current situation, Liu Lan is already very pleased, although it is impossible for Liu Lan, who knows the height of the sky, to satisfy his appetite at all, but you must understand the objective environment and conditions, all you can do is to continue to provide them with better conditions, so that they have a better environment to engage in this kind of work.

The soldiers' answers, although not the same, but all left three points of caution, although Liu Lan this is a surprise investigation, it is impossible for them to arrange it in advance, but if they continue to ask, there will be no gain, Liu Lan also turned around and went down the city tower and went to the county guard mansion with them.

He won't stay too much in Kaecheng, he came here to see the situation of Langya, and it can be regarded as cheering up the generals, after all, the first priority now is the Jizhou army, of course, in addition, there is another important thing, that is, the Liaodong Army will go south to Qingzhou, of course, in order to add firewood to the current Qingzhou, Langya will not sit idly by, of course, the premise of sending troops is naturally under absolute secrecy, and it cannot be in the name of the Xuzhou army.

If Liu Lan just wanted to make some trouble for Gao Ran at the beginning, then with the sudden killing of Hou Qian, everything has changed, what he has to do now is to make Qingzhou really chaotic, so that Yuan Shao can not move in Qingzhou, and this is the first priority of Liu Lan's trip, he wants to make the Liaodong Army and the Xuzhou Army closely linked in Qingzhou this time.

For this matter, Guan Yu wanted to take the order directly, but he didn't expect Zang Ba to take the lead, he has his own reason, after all, compared to the familiarity with Qingzhou, no one among the more than ten people here is more familiar with him, so if his Qingzhou army changes its flag and enters Qingzhou, it can have a more effective effect with half the effort.

"Okay, then this matter will be handed over to Xuangao, but the number of people should not be too many, just five or six thousand people."

Zang Ba stood up and saluted: "The last general understands, and he will start preparing as soon as he goes down." ”

Liu Lan nodded, in the past, Qingzhou was Liu Lan's heart disease, like a chicken rib, he controlled it, but Zang Ba has absolute autonomy, but whether it is Yuan Shao or Cao Cao, he can't ignore it, now it's okay, Qingzhou has become Yuan Shao's biggest headache now.

Moreover, the strategic location of Qingzhou is surrounded by all sides, the east is bordered by the sea, plus a Yellow River, sometimes Yuan Shao himself is powerless, so it is not easy to really control Qingzhou, and it also attracts the attention of so many people, if he does not solve the internal troubles, the external threat will only make him more and more dangerous.

Such an unfavorable geographical environment is a springboard for him to go south, and the strategic significance is extremely important, even if it has many hidden dangers, but Yuan Shao knows that if he wants to deal with Liu Lan, he must first get Qingzhou, just like this time the internal worries, his attitude is relatively optimistic, it is better to break out now than to happen in the future, so that he has no room for reaction, right? Otherwise, he is the real danger then.
