Exemption from taxes and land gifts are the best ways to attract displaced people. After all, the reason why displaced people become displaced people is because they are forced to leave their hometowns due to life or other factors.

"In addition, if it is passed on, as long as you are willing to come and settle in Bingzhou, in addition to the benefits just mentioned, no matter what evil things you have done, you can not blame me for the past!" Li Yi said in a deep voice.

"Understood." Guo Jia nodded. He understood why Li Yi was so anxious about the population, because there was too much vacant land in the state.

To put it simply, the population of Yanmen County is about 400,000, and the population of Shuofang, Shangjun, and Xihe, including those Xiongnu who surrendered, is only comparable to Yanmen County, but the smallest Shuofang County is also three or four layers more than the area of Yanmen County.

Throw away the mountains, forests, deserts and other areas that cannot live, and then remove the grasslands where the Huns livestock, there are still large areas of uninhabited places that are idle there. Although there is also a great price to be paid for land reclamation, as long as it is successful, the benefits are obvious!

"Hehe, it's easy to talk to smart people~" Li Yi looked at Guo Jia and smiled.

In the past, when Cao Xing was instructed, Li Yi had to tell Cao Xuan what to do, but now that it has been replaced by Guo Jia, Li Yi only needs to say a rough idea, and Guo Jia can refine it and convey it. Make a mistake? At least now, Guo Jia has never made any mistakes.

"By the way, how is the rhubarb crossbow making progressing now?" After discussing with Guo Jia for a while, Li Yi asked.

The big yellow crossbow, the crossbow arrow researched by the Han Dynasty, also known as the yellow shoulder crossbow, was an essential weapon in the Han Dynasty's war against Hu. This kind of crossbow ranges from the smallest one-stone crossbow to the largest ten-stone crossbow, and the strength required is very large, and the power required for a single stone crossbow is nearly thirty kilograms.

In fact, the legendary ten-stone crossbow is only available on the former Ruoyang and the current Chang'an City wall, and it is no longer a crossbow arrow, but should be called a ballista, because it is not only powerful, but also has a terrifying range of four or five hundred steps!

However, this kind of legendary-level crossbow arrows Li Yi has only heard of it, and has never seen it at all, but there are many one- and two-stone level crossbow arrows in the warehouse of Wushuang City.

These were all rations that Li Yi asked the imperial court to ration when the trapping camp was set up, but later after finding that it was difficult to imitate, he gave up using crossbow arrows. After all, it is very troublesome to maintain, and it is also very troublesome to shoot continuously, plus everyone in the trap camp is good at bows and arrows, so why abandon the bow and use a crossbow?

It's just that when he raided Hedong County before, Li Yi obtained two craftsmen who made crossbow arrows, which suddenly rekindled his interest in crossbow arrows.

After all, crossbow arrows are like arquebuses in later generations, and although they have various shortcomings, there are two advantages that cannot be achieved by bows and arrows in any way. One is to get started quickly, and a beginner can learn how to operate a crossbow arrow in a few days as long as his brain is not stupid and he is willing to work hard. The second point is that it is powerful, no matter who it is, a slight pull of the trigger can fully exert the power of the crossbow arrow.

Who wouldn't be tempted by such a weapon? A good archer requires more than just a long period of training, but also talent! And the ballistamen, they don't need this!

"Nothing has progressed." Guo Jia shook his head helplessly when he heard this, and said, "The manufacturing process of crossbow arrows is very complicated, and those craftsmen can't learn it in a short period of time. ”

"That's it......" Li Yi thought about it when he heard this, and suddenly, an idea popped up in his mind, and then he looked at Guo Jia strangely and asked, "Is it possible to make crossbow arrows alone?" ”

"Uh......" Guo Jia looked at Li Yi with a puzzled expression when he heard this, as if he didn't quite understand the meaning of his words.

"Let's take a look." Li Yi said, got up and walked out. Seeing this, Guo Jia didn't ask much, and hurriedly followed.

After a short time, the two came to a courtyard, and at this time, there were more than a dozen craftsmen recruited from all over the world, looking intently at the two old men in front of them to explain the production techniques of crossbow arrows.

"Meet the Prince! I've seen Guo Beijia. The appearance of Li Yi and the others immediately made everyone dare to come over and give a salute.

"Gong An, Gong Zhao, Ben Hou thinks that your method of teaching like this is not quite right." Li Yi said directly.

"Please also ask the prince to give advice." The two old men, known as An Gong and Zhao Gong, did not have any dissatisfaction with Li Yi's words, but only asked respectfully. With their age, they have long passed the age of impulsiveness, otherwise they would not have been directly brought to the Wushuang Kingdom by Li Yi.

"Although it is true that you are teaching the art of making a large yellow crossbow, it will probably take a long time for all of these people to learn it." Li Yi said in a deep voice.

"Junhou, the manufacturing skills of the rhubarb crossbow have always been very difficult, and there is no way to do it for a long time." An Gong shook his head and sighed helplessly when he heard this.

If he could, he also wanted to teach these people as soon as possible, so that they would complete the task assigned by Li Yi and could get a large amount of money to return to their hometown.

"Ben Hou naturally knows this, but there is one thing you are mistaken...... Li Yi shook his head and said, and then, looking at everyone's puzzled eyes, he said lightly, "What Ben Hou needs is a large number of rhubarb crossbows!" Although the talent that can make the Great Yellow Crossbow is equally important, for the time being, Ben Hou needs a lot of Great Yellow Crossbow even more! ”

Just listening to Li Yi's words, Duke An and Duke Zhao blinked, and then looked at Li Yi with a wry smile and said, "Junhou said that it was funny, if you don't teach them, just the two of us, even if we work day and night, we won't be able to make a few in a month." ”

"Hehe, so, there is a problem with your teaching method~" After Li Yi finished speaking, he didn't bother to continue to play dumb riddles, and directly explained, "Although the manufacturing technology of the big yellow crossbow is not clear to Ben Hou, Ben Hou believes that the entire manufacturing process can definitely be divided into several or even more than ten parts!" If everyone learns only one of them, how long do you think? ”

Hearing this, the two old men's eyes lit up, and they suddenly asked with a little shortness of breath, "What do you mean by the prince, making it separately?!" After speaking, but without waiting for Li Yi to speak, the two of them muttered to themselves, "Not bad! Not bad! You can! You only need to divide the rhubarb crossbow into more than a dozen parts, and the difficulty of learning will be much reduced, and even the assembly can be learned by a special person! ”

"That's the case, in this way, not only the speed of learning has become faster, but also the requirements for those who learn have also been reduced a lot~" Li Yi said with a chuckle.
