The tested assembly line operation has indeed greatly improved the work efficiency, Lao Yang still didn't believe it at first, and after seeing the convenient method, he didn't dare to look down on the little official in front of him, and his expression was more respectful. What Qin Yu has to do next is naturally simpler.

"Lao Yang, if you make gunpowder according to my method, you can definitely increase the power by more than fifty percent! Of course, this requires you to try and test, as long as you find the right way, you will be a great hero! ”

Qin Yu is still skeptical of the new gunpowder Lao Yang is very patient, after all, gunpowder has been like this since the Tang Dynasty, but Lao Yang still said slowly: "In this case, then we will try, if it is done, everything is easy to say, if it doesn't work, then there is no way!" ”

Qin Yu smiled and nodded: "That's right, quickly bring a pen and paper, I'll write you a rough recipe, but the specifics still have to be explored by yourself!" ”

After saying that, Qin Yu picked up the pen and wrote, Lao Yang stood aside and frowned, it's okay to adjust the proportion of the formula, what's the matter with placing egg whites? And grinding into granules? That's it, anyway, I did it according to Shangguan's requirements, and I can't be blamed if something happens!

After arranging the matter, Qin Yu left the gunpowder workshop and went straight to the general supervisor, who was responsible for the manufacture and research and development of military weapons. Qin Yu carefully observed the use of the eight-ox crossbow in the army, but it was unsatisfactory.

Qin Yu, who is dressed in tiger skin, is regarded as a Shangguan wherever he goes, and he will be a prisoner is naturally no exception, Shaofu Zhu Ping'an heard of Qin Yu's arrival, and hurriedly ran out to greet him, and said respectfully: "Shangguan is coming, I will be a prisoner, I don't know what is going on?" ”

Qin Yu looked at the general of the seventh rank official position, who was the eunuch and the young man, dressed plainly, and his face was not vegetable. It seems that he is a clean official, Qin Yu secretly gave an evaluation to himself, then nodded slightly, and said with a pleasant face: "It's nothing important, just pass by and take a look!" ”

Zhu Ping'an nodded and said, "Even so, why don't I personally lead Shangguan to visit?" ”

Qin Yu nodded, and followed Zhu Ping'an directly towards the general prisoner. Of course, Qin Yu's purpose this time was to improve the production method of the Eight Bull Crossbow and its various strong crossbows, and he naturally paid special attention to the crossbow production area.

Zhu Ping'an, who was bright-eyed and bright-hearted, naturally noticed the change in Qin Yu's eyes, and stopped directly in the crossbow area, and said suspiciously: "I don't know if Shangguan has any questions about the production of crossbows?" ”

Qin Yu pondered for a while and asked, "How many people do you need to operate an eight-bull crossbow?" ”

Zhu Ping'an said with a smile: "Shangguan said that it was funny, the eight-bull crossbow generally needs three to five people to operate!" ”

Qin Yu nodded thoughtfully and said, "Then what if it can increase its power, and only one person needs to operate it?" ”

Zhu Ping'an said with a smile: "Things are good, but they are difficult to achieve!" ”

Qin Yu also smiled and said, "If you don't try, how do you know?" ”

Zhu Ping'an arched his hand, but there was a trace of disdain in his eyes, he has used something for hundreds of years, you can change it if you say it?

Qin Yucai didn't notice Zhu Ping'an's eyes, and still said with a smile: "In that case, how about we make a bet!?" ”

Zhu Ping'an smiled disdainfully, his body was not afraid of the shadow, so he naturally straightened his waist and spoke, and said lightly: "How to bet?" ”

Qin Yu smiled faintly, such a person has seen a lot of himself, and he will not be convinced if he doesn't take out the real thing, and after thinking for a while, he said: "In this way, if I get something out, if it can improve the power and range of crossbows such as the Eight Bull Crossbow, if I have any new objects in the future, I ask you to build them, and you have to give priority to making them for me!" ”

Zhu Ping'an sneered and said, "No problem, although they will not serve as prisoners for private purposes, they can also meet your requirements, but what if you lose!?" ”

Qin Yu arched his hand and said, "If I lose, I will never be one step above the gate of the prison in the future!" ”

Zhu Ping'an nodded and said with a smile: "If that's the case, then it's up to you!" ”

Qin Yu didn't say much, he directly took out a few design drawings from his arms, handed them to Zhu Ping'an and said, "Just do it according to this, I have already marked the size and everything!" ”

Zhu Ping'an is also an expert, the pulleys of different shapes and sizes are clear at a glance when he gets them, he looked at the drawings in his hand, and he was very skeptical, is this thing really useful?

Although this type of pulley has not been done, the objects used on the bed crossbow are similar, and it can be modified to be done, but after a while, a few old workers came over with the modified pulley.

As a result, Qin Yu of the pulley looked at it and said with a smile: "Although such a thing is not qualified, it is barely enough!" ”

After saying that, Qin Yu went straight to an eight-bull crossbow that was to be assembled, and ordered the pulleys to be put in place one by one, but after a while, a new eight-bull crossbow appeared in front of everyone.

Looking at the exquisite shape, as if it was about to swallow the eight bull crossbow, everyone swallowed their saliva, Zhu Ping'an had a little determination, and hurriedly said: "Why don't we go to the school field and give it a try?" ”

Qin Yu nodded with a smile, and went straight to the backyard where the experimental weapons would be supervised.

"Whoosh!"

Five hundred paces away, a long arrow with red wings was firmly nailed to the wall, and the tail was still trembling and humming.

"Wow!"

Except for Qin Yu, no one present was in an uproar, a small pulley had such power! And it only takes one person to operate!

Zhu Ping'an Rao is accustomed to seeing the huge power brought by the weapon, and he can't help but be shocked at this moment, he knows very well what such a sharp weapon means to the enemy army when it appears on the battlefield!

Enjoying the awe-inspiring gaze of the craftsmen, Qin Yu was about to speak, and Zhu Ping'an said viciously to everyone: "Today's matter, the method of the new crossbow is strictly forbidden to be spread!" If there is a violator, the three tribes will be destroyed! ”

Zhu Ping'an naturally did not have the right to exterminate his clan, but now Qin Yuyou, who was holding Daoyan's private seal, saw Qin Yu nodding, and everyone shuddered and nodded again and again.

Qin Yu looked at Zhu Ping'an with a deep expression, Zhu Ping'an was stunned for a moment, then he reacted, smiled bitterly and said: "It's the lower official who lost, and he will definitely keep his promise in the future!" ”

Qin Yu nodded, and didn't know anything about it, so he said directly: "Now that the battle ahead is tight, and all the soldiers are fighting bloodily, we still need to continue to work hard to create more powerful weapons, and after the war, everyone will be rewarded!" Now, please return to your respective posts and step up the production of new crossbows! ”

Zhu Ping'an was like being beaten with chicken blood, and he didn't care about giving Qin Yu luggage and returned to the workshop with a group of craftsmen, and he had to be busy again these days, not only to remake the Eight Bull Crossbow, but also to remake other crossbows!

It can be said that the long-range attack power of the Yan Army today is increasing in geometric ability! The most important thing is that it not only strengthens the power, but also strengthens the range! The unsuspecting Southern Army will definitely be caught off guard!

……

"You mean, Qin Boy has been walking between the major workshops for the past few days? Not only did he make a new type of gunpowder, but he also improved all the crossbows, and his power was greatly increased? ”

Dao Yan was listening to Jin Yiwei's answer at this time, and was surprised in his heart, this kid didn't frame me, and he really made a lot of good things!

The brocade guard nodded, and said with a straight face: "Yes, sir, and according to various workshops, the power of gunpowder has increased several times!" I'll send you a detailed report in a minute! ”

Dao Yan nodded and said, "By the way, I heard that this kid also made an assembly line job?" I heard that the effect is not bad? ”

Jin Yiwei nodded and said, "Yes sir, according to the manager of the gunpowder workshop, assembly line operations can increase work efficiency by more than two times!" ”

Dao Yan nodded with a smile and said: "In this case, inform all the workshops that they are currently using this method, in addition, such a method and the method of making gunpowder must be kept strictly secret, and how long can it be hidden from the Southern Army!" ”
