When Yuan Yun led the triumphant gunpowder army back to Luoyang, he had already learned on the road that there were as many as 300 people sent by Enchanting Rao to attack Yuan's mansion.

It's just that after exterminating most of the people, there are still a group of people who rushed into the Yuan Mansion, and they all brought fierce fire oil with them, although this primitive fire oil is not as powerful as gasoline, but when a large number of fire people rushed into the Yuan Mansion, it still caused a lot of panic, and many maids were frightened and ran around, and finally Cai Wenji and Zhen Mi slashed a few people with swords, and the situation stabilized.

Seeing the mess in Yuan's mansion, Yuan Yun was constantly frowning, although there was no danger, but seeing such a scene, it was still a little thrilling, especially when he saw that the hospitality lobby in the front yard had turned into charred black ashes, it was very unpleasant.

The eldest sister Feng Xuan was very calm this time, and began to appease everyone after the matter was over, and assigned their respective tasks, otherwise the chaos would inevitably last longer, and the wives of Yuan Yun's family did not have any discomfort, they seemed to have been prepared for this kind of thing for a long time, which made Yuan Yun feel a little guilty.

This time he was able to quickly eliminate the assassins, and the biggest hero was naturally Tong Yuan, who temporarily lived in Yuan's mansion, when he saw a living person rushing into the front yard, he immediately held a long sword in his hand, and cut down when he saw the enemy, and there were definitely no less than twenty people who died in his hands.

It was also because of Tong Yuan's appearance that the first batch of assassins who rushed in panicked, and there was no chance to attack in formation, so that all of them immediately became scattered, and then gradually killed by the guards of the Yuan Mansion one by one.

After the head of the family, Yuan Yun, returned to the Yuan Mansion, he undoubtedly gave everyone a reassurance, and the whole house finally settled down, as for those who were killed or burned to death by the assassins, Feng Xuan also did the aftermath as soon as possible, and the houses of the neighbors who were burned down were also compensated, and everything was placed very properly.

When Cao Ang returned to the mansion with Yuan Yun, his face was a little ashamed, after all, when this kind of thing happened when Yuan Yun went on the expedition, as the Luoyang Commander, he was somewhat responsible, so it was natural for him to feel guilty.

Yuan Yun glanced at his courtyard, then glanced at Cao Ang, and then smiled: "The prince is just guilty, Luoyang is originally a commercial city, and the number of strangers who come and go is not very large, if you want to really do foolproof prevention, it is absolutely impossible." ”

Cao Ang nodded, because what Yuan Yun said was indeed right, the number of people entering and leaving Luoyang every day is 100,000, if this is all checked, I am afraid it will be really difficult to do.

Moreover, it is impossible for Luoyang to implement the access control system, if the caravans are closed by the access control, it is estimated that the four main roads in Luoyang will be blocked immediately.

The only effective way is to establish customs clearance documents, and those businessmen who come and go must be in Luoyang Mansion to look at this kind of document one step in advance, which also makes the loopholes that can be exploited become unusually many.

Yuan Yun saw that Cao Ang didn't speak, so he changed the topic and quipped: "I killed Zhang Lu's concubine in Hanzhong, and she single-handedly made the Hanzhong Civil Rebellion this time, so I have to talk to this Langzhong Marquis anyway." ”

Cao Ang finally smiled at this time and asked, "Are you planning to blackmail him?" ”

Yuan Yun stretched out a thumbs up, and then replied: "I have sent someone to send the bewitching head to Xudu, I don't know what Zhang Lu will do when he sees it, my letter is very clear, the key role of enchanting in this civil uprising, and Zhang Lu can't escape the responsibility, he can only hand over all the remaining sins, so that it is convenient for us to clean up." ”

Cao Ang pursed his lips and said, "Don't talk about these far, you haven't said what you're going to blackmail him yet?" ”

Yuan Yun saw that Cao Ang was not fooled by himself, so he could only sigh secretly, and then replied: "When Zhang Lu left Hanzhong, he searched the three layers inside and outside the three layers there, and now these people's fat and people's ointment have become his private property, do you know that he is really rich and rival the country, I sent a spy to his house, saying that when he went to Yecheng to surrender, he had already sent someone to buy land in Xudu, and also built a huge manor, it is rumored that the main house in his manor is made of gold, such a rich family, my little blackmail, it shouldn't be nothing, right?" ”

Cao Ang coughed again, and then followed the question just now: "Come on, how much have you blackmailed?" ”

Yuan Yun saw that he couldn't hide, so he could only smile and say, "I asked him to hand over ten thousand gold in exchange for the bewitching head, and hand over all the treasures hidden in Hanzhong, so that I, the marquis, can keep my mouth shut." ”

Cao Ang smacked his tongue and said: "With so much money, can Zhang Lu hand it over?" ”

Yuan Yun shrugged indifferently and said: "This is not something we should worry about, this time to suppress the Hanzhong Civil Rebellion, our Luoyang has suffered heavy losses, this cost he Zhang Lu can't afford to pay out, if this goods really dare not pay, I will let him know what is powerful." ”

Cao Ang shook his head helplessly, and said with a smile: "Did you put a lot of eyeliner next to Zhang Lu, otherwise how could he think of such a bad thing as you said, after all, he was also a hegemon back then." ”

Yuan Yun shook his hand and said: "Zhang Lu is a magic stick at most, the really powerful thing next to him is his chief staff Yan Pu, this person is scheming, in addition to me, there are many other secret agents placed in their mansion, you Lao Tzu will naturally not let go, so many secret agents are crowded together, and there are ghosts if they are not exposed, but Yan Pu ignores them, and lets Zhang Lu continue to reuse these people, it seems that he hopes that others can see what he is doing, so it is a good strategy to save his life." ”

Cao Ang touched his chin and said, "Then if you threaten you so nakedly, then Yan Pu will listen to you?" ”

Yuan Yun shrugged his shoulders and said: "Yes, how could it not, even if Zhang Lu is reluctant to give up those money, this Yan Pu will definitely persuade him to let go, otherwise once the matter in Hanzhong is stabbed to the court, Zhang Lu, an old man, is estimated to be unable to sleep in Xudu, who wants his background to be a god stick, many nobles and old officials in the court have long looked at him unpleasantly." ”

When Yuan Yun spoke, he actually looked at the robe on his body, and finally smiled, pointed to his nose and said: "Those old officials can't get used to me, so they always deliberately make things difficult for me. ”

Cao Ang heard Yuan Yun say this, he could only smile bitterly and shake his head, and said: "Who wants you to be negligent and actually make a big banquet on the way back, if the triumphant division does not return to its original place of residence, it is absolutely impossible to get drunk, this is a dead rule, you are good, it is not a matter at all, those old officials in the DPRK and China do not impeach you who impeach, this time you know the lesson, your military exploits have all been canceled, and you will be fined for one year." ”

Speaking of this, Cao Ang suddenly smiled bitterly again, and continued: "Brother Yun doesn't care at all, a one-year fine is nothing to you, as for military merits, it seems that you have always resisted, and today you have made great achievements, but you can't give you a suitable title of general at all, this matter was only recently discovered by me, I believe my father also encountered the same problem, that is, Brother Yun, you are in your current position, only when you started to kill Zhang Xiu, you have had military exploits, After that, all your exploits will always be wiped out by various things. ”

Yuan Yun's whole body trembled, and he hurriedly hugged his fists and said: "The prince of the world should not know anything, I just eat with a mouthful, I said a long time ago, the ghost wants to go to the battlefield, so after returning from this expedition, I plan to stay in Luoyang and not go out." ”

Cao Ang except for the helpless wry smile, there is really no way, now Yuan Yun still has only one position of marquis, the military position is really impossible to divide, can only be so embarrassing, if there is not such a position of marquis, it is estimated that he will not even be able to lead soldiers.

The two of them had already entered Yuan Yun's study, but fortunately they were not attacked by those assassins, which made Yuan Yun a lot of luck, otherwise if the fire burned, some of the drawings he had drawn before would have to be repeated.

After Cao Ang entered the house, he casually pulled out a scroll of drawings from the bookshelf, glanced at it and said in surprise: "This thing has wings like those gliding eagles, and the gas engine on this back is also installed, can it fly?" ”

Yuan Yun looked at Cao Ang's point, shook his head, and then put away the scroll of drawings, and then replied: "If this thing is to be realized, I'm afraid it's not a matter of a year or two, it's just that I was bored to draw before, and many basic things are not solved, this will always be a drawing." ”

Cao Ang had already passed the period of surprise for the things designed by Yuan Yun, and when he heard Yuan Yun say this, he just smiled and laughed, and finally added: "If it is really made one day, I will definitely go up and experience it." ”

Yuan Yun didn't pay attention to the design drawings of the plane, but spread out another volume of drawings, and then said: "The design of the assembly line has come out, in addition to the design drawings, a complete set of rules must be established, which is more complicated than the assembly line itself, so I just wrote the outline, and I still have to hand it over to Mr. Jia Xu later." ”

Cao Ang glanced at the drawings, and then roughly looked at the so-called outline, and suddenly wondered: "Why does the same object have to be divided into so many people to do it, wouldn't it be better to complete it alone?" ”

Yuan Yun said with a smile: "This is the essence of the assembly line, people have to complete a set of things, then there are definitely a lot of technologies to master, and these technologies are all taught to a person, that is a matter of many years, but as long as they are separated, it is different, the workers on the assembly line, as long as they learn their own technology, the rest will be handed over to others to complete, which can not only reduce the time for learning, but also make it more proficient, the most worry-free thing is that we no longer have to worry about the outflow of technology, because in addition to the old craftsmen we rest assured in the future, It's hard for anyone to grasp everything. ”

Cao Ang was a little unconvinced, but seeing that Yuan Yun was so sure, he didn't ask any more questions, looked at the outlines for a while, and finally pointed to the one at the end and said, "Can you really increase the current productivity by twenty times?" ”

Yuan Yun nodded and said: "Absolutely, twenty times is just my estimate, you must know that the endurance of these workers of ours is not ...... Well, it's not like anyone else, they're too hard-working, and they're definitely going to be very serious about doing this kind of work, and they can't be admired at all. ”

Cao Ang was a little puzzled when he heard this, taking his work seriously, it was originally his duty, what was there to admire, but now that he had a definite answer, he didn't care about those side details, just patted the surface of the drawings lightly, and then said with a smile: "Since it is so powerful, then we will start to implement it tomorrow." ”

Yuan Yun looked at Cao Ang's decisive appearance, and sighed in his heart, although the system of one person deciding everything in this era is destined to have many drawbacks, but the advantages are also extremely obvious, that is, efficient and fast.

Now that Cao Ang has made a decision, the first batch of assembly lines in Luoyang will officially be inferior to the process, so that in the future, Luoyang, a super factory, will really become an industrial city.
