My whole family traveled across time with an encyclopedia

Lu Cui was even more impressed when he heard that the other party figured it out alone.

He was able to grow to where he is today, relying on the superb technology passed down from his ancestors. It is conceivable that it is difficult to figure out a weapon by himself, let alone an epoch-making weapon.

Lu Cui couldn't help but sigh in his heart, if the other party grew up in his grandfather's era, maybe he could also become a master craftsman and be named a marquis as a woman.

Seeing that Lu Cui became more and more excited, Chang Yuan couldn't help but say, "Master Lu, don't scare Miss Ning. What do you think of this thing?"

Lu Cui restrained his emotions, and couldn't help affirming: "Why do you ask me, General? Haven't you tried its power before?" The thick log bullseye can pass through.

Ning Qingxi thought about whether this thing is good or not, but it is related to their food supply, so he couldn't help but added, "Hand crossbows have extremely strong penetrating power and can pierce armor."

Chang Yuan was surprised, took the hand crossbow from Lu Cui, and looked it over carefully again, "Come here, go and prepare me a scarecrow in armor."

After a while, a soldier with a scarecrow in armor erected it not far away.

Chang Yuan pointed at the armor and pulled the trigger.

The others stared at this scene with bated breath. If this little thing can really penetrate the armor, then this little girl is really amazing.No wonder Lao Lu respected her so much.

"Whoosh!"

The soldier standing next to the armor stepped forward and saw the arrow piercing straight into the armor, and couldn't help shouting loudly, "It's hit!"

"Hit it?!" Wang Hanting rubbed his eyes, as if he couldn't figure it out, how could such a small bow, like a child's toy, have such a big damage? !

The big man in the army couldn't help but look at Ning Qingxi secretly.

Chang Yuan held the hand crossbow, "Let's go, go back to the house immediately! Master Lu, please follow."

Even if Chang Yuan didn't say anything, Lu Cui would follow.

He still has a lot of questions to ask Ning Qingxi for advice.

Chang Yuan sat on the main seat with a big horse and a golden knife, "I can exchange food with you, just use the blueprint of this hand crossbow."

Ning Qingxi and Ning Changrong exchanged glances, and it was done.

The next step is to discuss the specific quantity, which has nothing to do with Ning Qingxi.

Her mission is over.

She just sat next to her, and after a while she was dragged by Lu Cui to keep asking questions.

"Miss Ning, this thing is called a trigger, right? How does it recover? After pressing it, I think it will bounce back by itself."

Now that the deal has been finalized, Ning Qingxi is no longer stingy, "Look here, does it look like it can be opened? In fact, there is something called a spring in the middle, which can make your trigger return after you press it down."

"Spring? What's a spring?"

During the conversation between Lu Cui and Ning Qingxi, he felt that his thoughts had been impacted like never before. He was like a sponge short of water, eagerly absorbing the knowledge that the other party said.

Ning Qingxi asked Fu Linjun for a piece of paper, then went to the kitchen to get a piece of charcoal that was half burnt, wrapped it in paper, and made a simple charcoal pencil.

They started to write and draw on paper. Anyway, they never thought that things would become like this, and the drawings would not be carried with them, so she simply taught and drew at the same time.

After she finished drawing the blueprint, Lu Cui also learned it.

Ning Changrong also walked out of Chang Yuan's study with a satisfied face.

Ning Qingxi, Ning Changrong and Chang Yuan greeted each other and went back to the room.

"It's wonderful, it's wonderful! It's really wonderful." Lu Cui was still muttering to himself while holding the charcoal-drawn straw paper.

After a while, he borrowed another piece of paper from Fu Linjun, and carefully copied the straw paper drawn by Ning Qingxi, then carefully folded the original drawing of Ning Qingxi, put it in his arms, and shook it The one he copied himself.

After it was dry, it was presented to Chang Yuan.

"Only when I saw Miss Ning today did I realize how shallow my skills were in the past. Hearing the truth in the morning, death in the evening is enough."

After Lu Cui sighed, he stepped forward, "General, this is the blueprint for making the hand crossbow. Miss Ning also created a marking method for the blueprint, not only marking the material, but also the size and proportion. This knowledge Lu used to Unheard of. But with these markings, even non-craftsmen can easily understand."

What Ning Qingxi wrote on the blueprints were not Arabic numerals, but all the characters of this era. Chang Yuan could understand the blueprints copied by Lu Cui at a glance.

"Can it be mass-produced in the army?" Chang Yuan was amazed as he looked at the blueprints. He had spent a huge amount of food in vain. You must know that the food he promised Ning Changrong was enough to feed 100 people for three or four years.

But after all, they took advantage of it.But this is already the maximum amount he can squeeze out.After all, in the war in the army, people eat horse chews, and the daily food is consumed in large quantities.

Lu Cui nodded, "It's a little troublesome. We don't have enough ore, and there are still some difficulties in the production process. A lot of blacksmiths are needed to slowly polish these hand crossbows."

Ning Qingxi did not mention that there is another method of pouring molten iron. People in this era use manual polishing, so the speed naturally cannot be improved.

Chang Yuan tapped his finger on the table, pondered for a moment, "Don't worry about the ore matter, we will be able to take Taixi County in a short time, presumably there are still some resources there, which should be barely enough, and I will send people to collect more in the future."

Lu Cui said again: "I discussed with Miss Ning before, if we don't have enough iron, we can use wood and bamboo instead, but the lethality may be reduced and it is easy to damage. If it is urgent, it is fine."

Chang Yuan nodded, "Okay, if it's okay, you can make a batch of bamboo slaves first."

Not everyone can afford armor on the battlefield. Bamboo crossbows may not be able to pierce armor, but it must be no problem to kill someone.And it is more convenient than bow and arrow.

After Ning Qingxi returned to her room, she started to pack her luggage. In fact, there was nothing there, mainly some small jewelry given to her by Mr. Fu Lin. Although she didn't usually need it, it was also his heart.

When Ning Changrong returned to the room, he told Ning Daniu and others about the matter. After Ning Changrong left, Ning Daniu and the others came to ask for a crossbow, and they couldn't fall asleep.The general's mansion didn't dare to wander around, so it could only sit there and wait.

After Ning Changrong left, Ning Daniu probably thought about it. He knew how important the hand crossbow was.

Originally, they wanted to sell glass to buy food, but now they can't buy food privately, so they should exchange it with others with hand crossbows. Sure enough, what Ning Changrong said after he came back confirmed his idea.

"Pack up and pack up, we can go back tomorrow afternoon."

Originally, he wanted to set off tomorrow morning, but it took time for people to prepare food, and the other party also reciprocated, willing to send someone to escort them.

After all, this transaction is Chang Yuan's benefit.
