"Kidding you, silly boy, hahaha. However, now that Qingming has passed, virtuous son-in-law? Tell me, what should the old man do? Uncle Lee's face suddenly turned from kind to hideous, and with the dim light, it was like a fierce spirit haunting the midnight.

"Father-in-law, this, you listen to your son-in-law explain to you first, don't get excited." I carefully moved my ass backwards and tried to keep a safe distance from Uncle Li, but the old guy's expression became more and more fierce: "Old man Cheng has been showing this in front of the old man all day long, don't you make the old man excited?!" "The moment I saw Uncle Li's green light, I already knew what was going on...... Rubbing my ass and escaping from the hall in embarrassment, I turned around in grief and indignation, and gestured a middle finger in the direction where Uncle Li was, Fuck, old thing, Cheng Lao hooligan is showing me my shit in front of you, can you get me to talk about this matter? It's clearly anger at me. Forget it, in line with the principle of respecting the old and loving the young, for the sake of you being my mother-in-law's father, I will spare you this time, this black foot, we should be bitten by a dog, anyway, we embezzled a lot of public property, and it was used as a reward for traumatic medical expenses, so when I thought about it, I felt a lot more balanced in my heart, there was no way, to deal with His Majesty the Emperor of the Tang Dynasty, we can only use the spiritual victory method.

Chang'an to the eastern capital of Luoyang cement avenue has been repaired, officially opened to traffic, from Chang'an to Luoyang travel speed than in the past more than twice as fast, and the volume of transport has increased greatly, in addition, the establishment of a new traffic norms: whether it is a pedestrian or a vehicle, all drive on the right, in fact, this is not a new thing, Qin Shi made a provision, "Ancient Rites" said: the road man from the right, women from the left, the car from the center, and Ma Zhou, that is, another prime minister of the Tang Dynasty, has been in the local implementation of pedestrians into the city gate to the right, The rule that people going out of the city to the left makes the flow of people at the city gate convenient, so this new road code has not caused much opposition, and the cement road is mostly for cars and horses, and the speed is fast, so it is natural to form a certain standard, otherwise, isn't it a mess?

Four-wheeled carriage, not to mention four wheels, six wheels can be made for you, saying that ancient China did not make a four-wheeled carriage is purely a joke, well, a big joke, the ancient tomb of the Jin Kingdom has also unearthed six-wheeled vehicles, but whether it is a four-wheeled car or a six-wheeled carriage is dedicated to the monarch's hearse, others have no chance to sit. In fact, this also has a considerable relationship with China's topography and road metallurgy. In fact, a bronze four-wheeled model has been excavated from the Qin cemetery in the early Spring and Autumn Period, why has it not been handed down? "If you can't do it, you can't do it." I think there are a few factors that make a horse-drawn carriage unpractical in China. Including geographical and climatic factors. Europe is the flattest continent on Earth, with an average altitude of less than 300 meters, at least 60% of which is plains, with the exception of the Alps being low mountains and hills. It is suitable for a four-wheeled carriage. The earliest known diagram of a four-wheeled carriage appeared in southern Northern Europe, also dominated by plains. On the other hand, China's topography is extremely complex, with plains accounting for only a small part of the country, and being surrounded and divided by mountains, plateaus, deserts, and lakes. While precipitation in China is concentrated in summer, ancient dirt roads are easily washed out, and two-wheeled vehicles are easier to pass than four-wheeled vehicles.

---------------------------------------------------- but the newly built cement road is extremely suitable for this type of car, first, large load capacity, second, two-horse drive, fast action, third, can drive on this road for a long time.

Of course, Uncle Li did not object, nor did he agree, but only allowed me to try it temporarily, after all, it is illegal for ordinary people to take a two-horse car, but Uncle Li also fully considered the problem of transportation volume, such as transporting grain, if you use a four-wheeled carriage, then it can greatly reduce the transportation cost. In addition, the more than 100,000 prisoners of war have begun to build a cement road from Luoyang, the eastern capital, to Jinyang, the northern capital. This avenue was made in preparation for the transportation of troops from Chang'an to Goguryeo in eastern Liaodong in the future.

And at this time, the envoys of the True Pearl Khan of the Xue Yantuo Department had already arrived in Chang'an. It was his uncle Sha Bo Luo Ni Shu Qi Jin as the main envoy, and his nephew Tuli as the deputy envoy, offering 3,000 horses and 3,000 mink skins to the Tang Dynasty to pay tribute, and made a confession for the last attack on the Tang border, and asked Uncle Li to return the nearly 200,000 servants and bones of the tribe and 100,000 Xue Yantuo prisoners of war, and promised Uncle Li that as long as these prisoners of war and population were returned, Xue Yantuo was willing to guard the border for the Tang Dynasty forever and never rebel, and would sacrifice 5,000 horses, 10,000 cattle and 100,000 sheep to the Tang Dynasty every year.

Uncle Li and I walked in the imperial garden, "Son-in-law, what do you think?" Uncle Li walked very leisurely, plucking the flowers and plants on the side from time to time, "According to the son-in-law, anyone can say this, and everyone can say it, do it or not?" I'm afraid that only the Pearl Khan himself knows. ”

Uncle Li glanced back at me: "You kid, you are always so cautious when looking at people. "Uncle Li is embarrassed to say that I live the belly of a gentleman with the heart of a villain, and I said it more tactfully, but I still insist on my point of view." Father-in-law, even if Xue Yantuo True Pearl Khan can really keep his promise, but what about him? How can we guarantee that each of their khans will be trustworthy? Besides, if our Tang Dynasty failed to defeat Xue Yantuo this time, I am afraid that the request of the envoys they sent would not be like this. ”

"Yes, just like you said well, there is no eternal peace between countries, and there is no diplomacy between weak countries...... If my Tang Dynasty wins weakly, don't say it's Xue Yantuo, I'm afraid that even the surrounding subject countries will rush up to get a piece of the pie, hmph, Zhenzhu is a good abacus, but he didn't expect that the old man's subordinates, and the virtuous son-in-law, you are such a person, hahahaha......" Uncle Li laughed silver. We have to laugh together, what kind of person, what kind of thing is not good to do, what are you laughing at.

The imperial garden is really big, I walked around with Uncle Li for more than half an hour before I walked less than half, at this time, well, it seems that Uncle Li drank too much tea, a little anxious, but there is no thatched house nearby, fortunately, the old guy reacted quickly, and pointed to the flowers indiscriminately: "The old man went to take a look over there, and the virtuous son-in-law stayed here for a while." ”

Uncle Li was agile and cut through the thorns, and after a while, I heard that familiar voice, damn, can't you water the roots of the tree to reduce the noise? Not a little bit of public morality, defecating everywhere, despising this old rascal, boring!

After a short time, Uncle Li went home, walked over, and pretended to be nothing, and it seemed that this old rascal often did this.

"Well, what are you doing squatting there, let's continue the topic just now, according to what you said, those people and prisoners of war will not let go? Hey? What is this doing? Uncle Li glanced back at me and motioned to move on, but found me squatting in place in a daze, staring at the flowers and plants on the side in a daze.

"Son-in-law, what are you doing?"

"Isn't this a cotton leaf?" I pointed to the green thing that pulled out the half-tall branches. I know cotton, but it's only April now, and the cotton peach hasn't been seen yet, and if it weren't for Uncle Li running to defecate everywhere, I really wouldn't have the time to study what it is.

Uncle Li glanced at me and said with a smile: "What is this, there is nothing in our imperial garden, this thing is the tribute of Gaochang back then, also known as white boil, picking flowers can be woven into cloth, some people call it white boil cloth, some people call it cotton cloth." However, the price of this thing is too high, and the money has always been unable to buy even a horse. ”

"I know this, the last time I cleaned those hot air balloons, my son-in-law saw cotton cloth in the shop of the big food merchant, but my father-in-law, this thing is a good thing......" I don't know how to explain to Uncle Li, and I waved my hand for a long time before I held back a sentence: "Even if it can't be made into cotton cloth, you can use it to fill the interlayer of clothes, and it can also take the warmth effect, which is of great help to my Tang Dynasty soldiers in winter combat, not only that, this thing likes drought, the Western Regions, the whole territory of Longyou, and the northern part of Guanzhong Road, It can grow in these places that are not suitable for growing food. It's a treasure all over its body, and its cotton seeds can be used to extract oil, and although the oil is inedible, it can be used to make soap......"

----------------------------------------------------I'm very eager. What is cotton, a world-famous cash crop, its role is not just to take the stuff in the sandwich of the clothes to keep warm. Soap, that is, the biochemical weapon I made in the early days, has been painfully learned from me, and I consulted several experts who specialize in making pancreas in the palace, and came to the conclusion that there was a great mistake in the materials used by this son, but because of the difficulty of extracting animal fat, there was no ambition to continue the development.

This is a fact, the current living standards of everyone are not up to the meat, take so much oil to produce soap, first, will reduce the living standards of the working people, this is called competing with the people for fertilizer, second, will affect the price of fat meat in the market, now is not comparable to the future, fat meat belongs to the people's high-end food, so, I can only regretfully give up the plan to build a large soap workshop, but after seeing cotton, my heart that is obsessed with making a fortune instantly became hot again.

First of all, cottonseed is big, high oil content, large oil yield, but its oil can not be eaten, remember that we called cottonseed oil infertility oil, what is the specific statement I forgot, in short, eating this thing seems to deprive men of reproductive rights. Since it can't be eaten, its fat has another use, and that is to make soap.

Uncle Li glared at me, and said for a long time, "What is soap?" ”

I quickly explained: "It's the pancreas, let's use it to wash our clothes and wash our bodies." ”

Uncle Li suddenly pulled out and left: "Zhao Kun! ”

"The subordinates are here!" Zhao Kun didn't know which hole he suddenly came out of, startling Lao Tzu, he obviously didn't see someone next to him just now? Whether this guy knows the Five Elements Escape Technique, I have to ask for advice another day.

Uncle Li wrenched his fingers: "You immediately go and summon the Ministry of Works." By the way, I ordered someone to go to the shop in the East Market immediately and buy me some white cloth. ”

Hearing Uncle Li say this, I hurried to Uncle Li's ear and muttered a few words, Uncle Li nodded, stopped Zhao Kun, who was about to leave, and said: "When you buy white boiled cloth, by the way, buy another three or five catties of white boiled flowers, remember, it's that kind of white and fluffy thing, don't look away." ”

"Subordinates obey."
