People are terrible, when Jia Yi listened to Li Jing's story, he could only think so, after all, Jia Yi was just to go out and relax at the first time he received the emperor's holy decree, although this place is not a good place to relax, but Jia Yi, who knows the characteristics of smallpox deeply, believes that as long as he is particularly careful, he should not be infected.

But who would have thought that it was just a temporary and decisive trip, which would bring such a big trouble to Li Jing, and the matter had come to this point, it was useless to say more, it happened that a crossbow had just been developed, and the old and the young should try new weapons here.

"Your crossbow isn't very powerful." Li Jing played with the hand crossbow made by Jia Yi, and after test-firing an arrow, he directly gave such an evaluation.

"It's easy to say, you can change the crossbow, even if you change it to a five-dan bow, it won't take too much effort."

The pulley set made by Jia Yi himself was enough to support the strength of the five-dan bow, so he said this sentence with confidence.

After Li Jing listened to Jia Yi's words, his eyes lit up again, if he could really support the five bows, wouldn't it mean that there were countless more marksmen in the army?

After listening to Li Jing's words, Jia Yi's face was full of wry smiles, Li Jing's idea was too naïve, the material of the five-dan bow was too difficult to get, and it was already thankful that ordinary steel could be made into a three-dan bow, and the steel that could make the five-dan bow was not something that the current Datang could make, and it was already good to make the existing five-dan bow into a crossbow, and it was a fool's dream to mass-produce it.

"General, it doesn't seem that it is so easy to make a five-dan bow." You can't talk to Li Jing too straight, otherwise you can't tell what kind of damage you will suffer.

Li Jing was stunned for a moment, knowing that he was in love, he smiled bitterly and said, "Have you thought about how to apply this kind of hand crossbow?" ”

"The crossbow of the hand crossbow can be made foldable, I am trying to save trouble, so I did not make that kind of production, and after the folding hand crossbow is made, the boy is ready to prepare a large number of equipment to explore the horse camp, so that their ability to protect themselves will also increase a lot again, and if there is any decapitation action, they can also use the hand crossbow in their hands to make a try, instead of using their own lives to die with the enemy as before."

"Good boy, always remember the safety of the soldiers, and don't lose my generosity." Li Jing laughed with great relief, and gave high praise to Jia Yi's attitude and performance.

After talking for a long time, Li Jing's freshness about this crossbow had passed, and then he cared about the plague.

"How well is Doctor Sun treating the plague?"

At the mention of this, the smile on Jia's face will quickly reced, and then a depressed expression will crawl all over his face.

Seeing the change in the expression on Jia's face, Li Jing couldn't help but wonder in his heart, didn't Doctor Sun just go to treat smallpox, how could this Jia Yi be the same as what happened to him, thinking of this, Li Jing was suddenly shocked, this Doctor Sun shouldn't really have something happening, if something happened to Doctor Sun, then this tricky village would really be destroyed, because if Doctor Sun failed, then the entire Datang Dynasty would no longer be able to find anyone who could treat this disease.

"Doctor Sun has an accident?"

"No, he's alive and well."

While Li Jing's heart was at ease, his doubts arose again, Doctor Sun is fine, who is your expression for?

"Alas, don't mention it, my sister-in-law, go and help Sun Shenxian find a cure for smallpox."

"Huh?!"

After Li Jing listened to Jia Yi's words, his face was full of surprise, he had also seen Lin Meiyu, a very shrewd and capable little girl, but he didn't see that Lin Meiyu still had superb means of curing diseases.

"General, you think badly." Looking at the strange expression on Li Jing's face, Jia Yi knew that this Li Jing must have thought of Lin Meiyu as a holy hand of medicine, so he shook his head helplessly and told the whole story little by little.

After listening to Jia Yi's story, Li Jing couldn't help but sigh for a while, he couldn't imagine that Lin Meiyu, a little girl, would have such a vigorous and resolute side, and at the same time, he was full of admiration for her in his heart, reached out and patted Jia Yi lightly on Jia Yi's shoulder twice, comforted Jia Yi, and told Jia Yi to be sure to treat others well, and never let them down.

Jia Yi nodded thoughtfully, if this matter is successfully passed, although Lin Meiyu will definitely be rewarded by the emperor after helping Sun Simiao experiment with smallpox prevention methods, and Jia Yi is also very clear that Lin Meiyu's request must be to marry him, but if the emperor hesitates at that time, Jia Yi will definitely stand up as soon as possible, no matter what the price is, Jia Yi must also let Lin Meiyu become his wife.

No matter where it is, Jia Yi will not be treated badly but it must be his mouth, Thorny Village is located at the foot of the Qinling Mountains, and there will be no shortage of various biological resources, although there is a smallpox virus in the village, but Jia Yi believes that Qinling will not be affected in any way, otherwise it will not be just the Thorny Village that will have smallpox.

Hare pheasants and other wild meat, in Jia Yi's spare time, will become a dish on his table, the bitterness in his heart is impossible to eliminate before Lin Meiyu walks out of the tricky village safely, since this is the case, then turn the bitterness into appetite, eat and drink.

The hand crossbow was made, but Jia Yi only played it once, and it became a toy in Li Jing's hands, and he also asked Jia Yi for the drawings for making the hand crossbow, so that the soldiers behind him found a lot of blacksmiths, and camped not far outside Jia Yi's tent.

After watching the blacksmiths see the high fence around Thorny Village and the people gathered in it, their bodies can't help but start to tremble, and they are afraid that they will also become one of those people, so that there are always a lot of mistakes when it comes to crafting the parts needed for the crossbow.

Li Jing, who was furious, directly yelled at all the blacksmiths: "If you don't do it well, I will throw it all into it for you in a while." ”

All of a sudden, all the blacksmiths knelt on the ground, swearing that they would definitely make those parts in strict accordance with Li Jing's requirements, which eliminated the anger on Li Jing's face, and the blacksmiths finally took up the job.

The bored Jia Yi lost the toy he had just made, although he could go to Li Jing to chat when he was fine, but more often, Li Jing still liked to debug the hand crossbow he had just made, and he didn't have time to deal with Jia Yi at all.

In order to find a new toy, Jia Yi finally remembered that the telescope he had always wanted to make had not yet started to be made, and after ordering someone to go home and get a few pieces of glass for himself, he selected the remaining iron plates, and Jia Yiyou began to beat and get busy.

There is nothing too difficult to make a telescope, it is nothing more than two convex lenses, plus a long tube, and the length of the tube can be adjusted to adjust the magnification distance of the telescope, and the most difficult thing may be to polish the lens.

"Ziziga"

Metal and glass rubbing violently will make this kind of sound, I really don't know if it continues, Jia Yi will be driven crazy by himself, you must know this kind of piercing sound, even those villagers who are a hundred meters away are a little unbearable, knowing that it is impossible to go out, they have scolded in the direction where the sound came from, expressing their dissatisfaction, if it weren't for the soldiers who were waiting outside, maybe they would have rushed out to beat Jia Yi violently.

Li Jing also came over to take a look, and asked Jia Yi what he was doing, but he didn't say anything, kicked Jia Yi's ass fiercely and told him to be quiet, and then returned to his own camp and continued to check whether the hand crossbow he had just made was qualified.

In two days, Jia Yi finally got the telescope out, put the telescope in front of his eyes and took a look, and found that the effect was still very good, although the polishing was not very fine, resulting in a slightly blurred scene in the distance, but this is already good, when the time comes, take these two lenses back, make a mold, and then start mass production, I believe that the telescope made by then will be much better than this.

Just when Jia Yi was looking around with a telescope, he suddenly found that there were several wisps of smoke and dust coming from the direction of Chang'an, and after a closer look, he found that the leader was Qin Qiong, who was followed by Cheng Yanjin and other generals of the older generation, as for Jia Yi's friends, they didn't see any of them, and they had always been put at home by these old guys, after all, no one knew if there was really no danger here, in order to keep their family behind, they didn't dare to take their heirs with them.

Seeing this group of veterans, Jia Yi was not excited to greet him for the first time, but put the telescope he had just made into his arms and hid it, these old guys are all bandits, and when they see good things, they don't have the consciousness to return them after they take them and play with them, Li Jing is the best example.

After pinning the telescope to his waist and making sure that he would not be discovered, Qin Qiong and the others also came to the front, so they slowly stepped forward and said hello to a kind of veteran one by one.

"Stinky boy, after I heard that you came here, I still scolded Li Jing for coming, don't thank me, it's my old lieutenant who is angry with you late." Wei Chigong's loud voice, one mouth, that broken voice drilled into Jia Yi's ears, I really don't know if he was really stupid, he actually said such things outside Li Jing's tent.

Jia Yi, that Khan, I thank you sister, Li Jingke is not very far from here, and sure enough, he turned his head slightly and found that Li Jing had walked out of the tent with a black face.
