Especially Xiao Shilang, who is nicknamed "Desperate Shilang", fucks, he has already made nine small achievements.

That kid relied on his youth, he only slept for more than two hours a day, and his martial arts were not necessarily higher than his own, but he was a bold thief, and he dared to break into the robbers' den in a neighboring county, and now he firmly occupied the first position on the merit board, how could this kind of person fight with him?

Since you can't fight, then you have to get by, it's not that you don't work hard, but your life is not good, if it was himself who passed by Master Dong's shoe stall, he believed that it would definitely be him Wang Quan who was sitting in the county lieutenant's office now.

Zhan Yuan was just lucky.

After standing behind Jin Muxing and thinking for a while, Wang Quan finally saw the figures of Lord Lu and Lord Hou.

Lu Yuan stepped forward and said: "Zhanyuan, Yuanwu, the sky is cold, why do you want to move the people so much." ”

"Lord Lu and Hou County Wei Ken came to the Changwei Dart Bureau, we should wait here." Jin Muxing smiled.

Jin Yuanwu waved his hand and introduced: "Lord Lu, County Lieutenant Hou, this is Jia Yan." ”

"Golden Dart Head." Hou Kaishan nodded.

"Lieutenant Hou is polite." Jin Muxing returned the salute.

"Changwei Dart Bureau can produce so many talents, it is enough to see that Mr. Jin has taught well." Lu Yuan praised.

Jin Muxing smiled on his face, and arched his hand: "Lord Lu is too awarded, and the Changwei Dart Bureau can have today, all thanks to Lord Lu's support." ”

"Yuan Wu, what about the two of them? Take me there. Lu Yuan said lightly.

Jin Yuanwu responded and took Lu Yuan in.

Waiting for Lu Yuan to walk away, Jin Muxing frowned and said, "Laneige, Yuan'er, did I say something wrong just now?" ”

Wang Quan is also a little strange, what the master said just now is no problem, why does Lord Lu look a little cold?

Zhan Yuan was considering the wording, but Jin Lanzhi had no scruples, and said coquettishly: "Daddy, Lord Lu doesn't like others to talk about carrying or something, he has always been rewarded for meritorious service, and punished for mistakes." ”

Wang Quan nodded, and said in his heart: "So that's the case." ”

Jin Muxing patted his head and said, "It's because my father is confused, I haven't experienced this kind of occasion, and I really don't know how to speak." ”

"Daddy, didn't you say before that there was still a history of thorns coming to our house to support darts? Could it be that Lord Lu is more terrible than the history of thorns? Jin Lanzhi laughed.

"At that time, my father was still young, can it be the same?" Jin Muxing didn't have a good airway, so he followed in, ready to entertain and make up for the gaffe just now, and Wang Quan followed.

Jin Muxing thought that Lord Lu would ask Jin Yuanwu to bring Lu Yun'er and the others to the lobby to meet him, but when he arrived in the lobby, he found that he was not here, but went directly to the woman's guest room named Lu Yun'er.

Walking to the courtyard where the guest room was located, I saw Jin Yuanwu and Hou Kaishan guarding the door, Jin Muxing stepped forward and asked, "Yuanwu, who is that woman?" ”

"Dad, this is a secret of the Yamen."

Wang Quan couldn't help but sigh, only the senior brother dared to talk to the master like this.

"Okay, okay, I don't ask." Jin Muxing said with a smile, only then did he realize that Lord Lu was really here for these two people, so he waited at the door with Jin Yuanwu, and the others followed him and stood outside the door.

"Dad, go to the lobby and wait." Jin Yuanwu frowned.

Jin Muxing was afraid that he would do something wrong again, so he hurriedly said, "Okay, then I'll go to the lobby and wait." ”

Wang Quan naturally followed the master away, and finally turned his head to take a look, just in time to see Miss Xia and Peter Pan in the other two rooms walking out and talking to the senior brother.

In the guest room, Lu Yuan was playing with Lu Yun'er's small crossbow, and after carefully observing the complex mechanism on it, he praised: "It's really exquisite!" ”

"If the adult likes it, the folk girl can give it to the adult." Lu Yun'er said softly.

"That's not necessary, Miss Lu, do you know what kind of energy this crossbow uses?" Lu Yuan pondered for a long time and asked.

"Energy?"

"Let's put it another way, does Miss Lu know why a hand crossbow can shoot such a powerful crossbow?"

Lu Yun'er thought to herself: "Could it be that this Lord Lu is also a master of organs?" He replied, "Naturally, the strings in the crossbow are used." ”

"Where does the power on the strings come from?" Lu Yuan asked again.

Lu Yun'er was stunned, not knowing the meaning of his words, and shook her head.

"It comes from the force exerted by our hands when we wind up, and the power exerted by our hands accumulates on the crossbow strings, and then bursts out in an instant, which is the transfer of energy."

Wang Gui suddenly asked, "My lord, I don't know what kind of energy you are talking about?" ”

"As long as an object can do work externally, then it has energy."

"Do your work?" Wang Gui looked even more confused.

Lu Yuan scratched his head, the reason why he said this to them was to guide them to break the limitations of their thinking and develop towards hot weapons earlier, in ancient times, if the agricultural civilization wanted to completely defeat the nomadic civilization, hot weapons were extremely crucial.

But this matter is not so easy, Lu Yuan was not particularly good at physics in his previous life, let alone teaching others, after thinking about it, he decided to use a simpler statement.

"Have you ever noticed that when fireworks explode, they can produce a strong impact and shake stones away?"

Wang Gui nodded, but he still didn't understand the purpose of this lord suddenly asking them to say this.

Lu Yun'er looked thoughtful and asked, "Lord Lu, do you mean that energy is always being transmitted, and the explosion of fireworks is a phenomenon of energy transfer?" ”

As a descendant of Lu Gong, she also thought about the principle of fireworks explosion.

"Yes, yes, but it's not just about transmission, it's about transformation, when fireworks explode, heat energy is transferred into kinetic energy!" Seeing that Lu Yun'er was able to understand a little, Lu Yuan was overjoyed.

"Lord Lu, what you want to talk about is the use of gunpowder." Lu Yun'er said softly, she finally understood that this adult had gone around in a big circle, and in fact, she still wanted to let herself be a weapon for him.

"The application method is only the result, I hope you can figure out the principle so that you can better study." Lu Yuan smiled and said, "Okay, you can think about these things slowly in the future, can I take a look at the drawings of your cloud crossbows, cloud cars and boats!" ”

The two of them had already prepared, and took out the sketchy drawings they had drawn last night, and Wang Gui said, "My lord, the more detailed drawings will take a few days to be completed." ”

"The ship's business is not in a hurry, you can take your time." Lu Yuan smiled.

Lu Yun'er pointed to the two weapons on the drawings and said, "My lord, the cloud crossbow is a large repeating crossbow, six feet eight inches long (one foot is about thirty centimeters) and three feet one inch wide. The cloud cart is a catapult that is simpler to make. ”

Lu Yuan said happily: "Okay, your two weapons are very helpful to me now, Uncle Wang, Miss Lu, I want to set up an engineering workshop, with the two of you as the person in charge, are you willing?" ”

Lu Yun'er and Wang Gui glanced at each other and said in unison: "Yes." ”

Lu Yuan nodded with satisfaction, and said: "But at the moment, this sapper workshop is just an empty shell, I will arrange a place for you to live, and when the workshop is built in the future, I will allocate people to you, at the moment you are all in the county government to serve as a soldier, you don't need to go to the county office every day, just do research at home!" ”

"Thank you, sir." Lu Yun'er said happily, as long as the other party can take her in, she will be very satisfied, not to mention that the conditions are not harsh, she knows that the person followed by Brother Wu must not be a bad person.

"My lord, if the two of us stay here with the adults, we may cause trouble to the adults." Wang Gui hesitated for a long time and spoke.

"If there is really trouble, we will face it together after the expiration and find a way together, and the old man can live with peace of mind." Lu Yuan smiled.

Wang Gui nodded vigorously and said no more.

Out of the room, Lu Yuan resigned from Jin Muxing's invitation to leave for dinner, and left the Changwei Dart Bureau, leaving Jin Muxing with a worried face, thinking that Lord Lu was still blaming himself.

Out of the dart game, the sun has come out outside the house, the ice and snow are quietly melting, this time is the coldest, Lu Yuan wrapped his hands in his sleeves, and while walking on the street, he enjoyed the snow scene on the side of the road.

"My lord, shall we go back to the county government next?" Hou Kaishan asked.

"No, let's go to Zhang's Mansion next and visit Ma Zhutou." He still remembers the matter of Master Lu Yutong, so he must ask about it today.

……

Changxi County, Quanzhou, Jiangkou Daying.

Liu Zihao was feasting with his subordinates in the camp, and suddenly, a person walked into the camp tent and bowed down: "My lord, Commander Yu returned victorious." ”

"Really? Let him in. Liu Zihao said lightly.

A general sitting on the left hand smiled: "It's just to deal with some barbarians, and it's embarrassing to say that you will return victorious?" ”

The rest of the generals burst out laughing.

Yu Xun outside the camp naturally listened to it, his face became extremely cold, he closed his eyes for a moment, and when he opened them again, the expression on his face had returned to normal.

Walked into the camp tent, landed on one knee, bowed down and said, "The last general Yu Xun meets the general." ”

He was extremely tall, nearly seven feet tall, and after kneeling on the ground, he stood up on his own without waiting for Liu Zihao to speak.

Seeing that he was still so rude, Liu Zihao was secretly angry, and said coldly: "Sit down." ”

He has always looked at Yu Xun unpleasantly, and if he hadn't been instructed to follow the example, he would have been demoted long ago.

Yu Xun was about to sit in the backmost position of his left hand, but Liu Zihao pointed to the last position on his right hand, which was the last position, and said with a smile: "Commander Yu sits there!" ”
