With the rapid expansion of the population, the number of main roads leading from Chihkan to the western industrial area has also increased to three.

Except for the first one, which is a cement pavement, the other two are paved with asphalt. There is no shortage of bitumen these days: the petrochemical sector's poor oil processing capacity is responsible for the large production of bitumen.

Including the stalks of various "No. 50" gasoline, there have been a lot of jokes on Miao Su's side in a short period of time, and titles such as "Venezuela in the 17th century" have long been no longer news in the forum.

However, there is no way to do it on the petrification side. With the current industrial capacity of the country, if you want to turn black crude oil into various refined oils, you can only distill under atmospheric pressure, so it is normal to have more waste products.

To further process and refine petroleum, hydrocracking is required. However, these processes require a variety of pressure vessels and piping...... At the mention of the word "pressure", the Industrial Party fell to its knees.

Any kind of pressure vessel is essentially a bomb. Whether it is a pressure cooker or a gas tank, these things cannot be produced without a mature industrial system. If you force yourself on the horse, just wait for the serial bombs.

Crossing the public now neither light up the welding process, nor produce qualified steel, even the atmospheric valve is so-so, to produce a huge volume, higher level of petrochemical equipment, this is tantamount to the Arabian Nights.

Petrochemical equipment is an industrial pearl, even if it is a small chemical plant, all kinds of corrosion-resistant towers, kettles, tanks, valves, and pipelines are not within the reach of a poor and white dick silk force.

In later generations, those local tyrant oil-producing countries seemed to produce millions of barrels of crude oil per day, but their own refined oil was still imported. The petrochemical industry can only be played by hooligans, such as ethylene complete sets of equipment, such high-precision, even rabbits, until the beginning of the 21st century to break the patent monopoly.

Therefore, there is a reason why Venezuela has become that kind of ghost, without the support of manufacturing, the country will always be duckweed in the wind.

And the crossing country is now similar: Syrian child laborers light firewood to distill crude oil under an open-air tin cabinet, and the same is true for the oil workers of Miao Su, the difference is that Miao Su is full of forests and there is enough firewood.

This primitive distillation method is standard in the initial stages...... Don't worry about being embarrassed, Rockefeller did the same thing in the beginning.

Poor refining capacity is the culprit of high asphalt yields. Miao Su now produces gasoline and diesel, lubricating oil, and lamp oil every day, and these products add up to only 1 ton, which is really sad for those who hear it, and tears for those who listen to it.

Most of the crude oil turned into asphalt and was paved on the road. This kind of building material, which makes the road surface smooth as a mirror, can only be said to be a consolation compared to the more useful gasoline and diesel......

......

In the middle of December 1628, after someone ascended the throne, in the afternoon, Erma Road.

Usually the morning and evening are when the road is at its most utilised: tens of thousands of commuting workers take over the road like a tidal wave, and the scene is spectacular.

Today is no exception. On the smooth road, there was a sudden sound, and the faint black smoke of commuter cars was slowly passing by.

At four o'clock in the afternoon, it is the most lazy time: the workers returning home from shift sit lazily in the car, and the road is empty and not crowded; They bask in the warm sun, blow the gentle sea breeze, enjoy the continuous lagoon by the sea, and arrive home before they know it.

This gas commuter with a string of open-top wooden cars hanging from the back is already a second-generation model. Thanks to the increasing metalworking technology in the kiln area, the early wood-wheeled cars have been replaced with steel-wheeled vehicles, and the early shock-absorbing leaf springs have been replaced with pinky-thick springs, combined with the smooth asphalt road, so that the passengers' driving experience has been greatly improved - at least not hemorrhoids.

Just as the No. 0137 commuter car was slowly moving from north to south, a horse-drawn carriage with clattering hooves came across the road.

With the urine nature of "everything must be standardized", this carriage is naturally no exception.

The carriages are numbered, and the standard horse-drawn carriages belonging to the bus company are Western-style four-wheeled models. In this case, two horses stand side by side, with leather cords on their bodies, while the driver at the front of the carriage is carrying the horse with ease, who can control the horse with a shaking of the rope and a soft shout.

Traditional Chinese-style vehicles are hard-wheeled. The cart had only two wheels, and the wheels were mounted on the shoulders of the horses with hardwood, and the horses were not only responsible for the force of the vehicle dragging forward, but also a part of the downward gravity of the vehicle and the groom sitting on the wheels.

This resulted in the slow speed of the carriage, the easy fatigue of the horse, and the low efficiency of transportation.

Western-style carriages, which use soft ropes to transmit the pulling force, do not have this problem: the horses are only responsible for the drag forward, and the gravity of the body and passengers is all carried by the four wheels.

Anyone who has watched Western movies knows that whether it is a horse-drawn carriage pulling a box on the streets of London or a caravan during the pioneer of the American West, it is this four-wheeled structure suitable for long-distance transportation.

At present, Dayuan is no exception: the horses bought from Daming by crossing the country are all equipped with standard four-wheeled freight carriages.

After the driver pulling a cart of white radishes saw the driver of the commuter car, Lao Yuan began to wave his hand, and when the two sides were about to stagger together, the groom threw over a fist-sized white radish: "Lao Wang, taste the radish, the water is big, and the ground will only harvest it!" ”

The driver, Lao Wang, stretched out his hand, not wanting to catch the radish, but was picked up by the workers in the carriage behind him. A few workers laughed and took a bite and killed the radish with a click. The driver laughed and shouted to the groom: "Go to your house for a drink at night!" ”

"Don't come at night, go to the cafeteria and meet!" As the groom drove away, a crucial message floated over: "The swine fever of the Seven Bridges!" ”

"Ahh Pigs have another plague!? After receiving this information, everyone, including the driver and passengers, was immediately overjoyed. The next moment, Lao Wang, who was wearing indigo canvas overalls, turned on the power of the gas generator to the maximum, so the speed of the front of the car quickly increased, and dragged the whole string of carriages happily towards the terminal "Seven Bridges".

"Seven Bridges" is a place name. As one of the countless small bridges built by the crossing public on the Tainan Plain, the "Seven Bridges" are very inconspicuous. The only thing that people can remember is probably the pig farm near the Seven Bridges.

......

At the same time as the commuter car was rushing to the terminal, a motorcycle was speeding past the "Seven Bridges" made of prefabricated concrete slabs.

It's a Harley-Davidson motorcycle. The classic elevated body, the flowing tassels, and the rider wearing a leather jacket and leather boots, the strong hippie smell can be smelled from afar.

The only thing that is a little jarring is this: sitting behind the rider in sunglasses is not a chick with her ass cocked, but an iron cage...... It contained two black-skinned piglets screaming.

After driving over the Seven Bridges, the motorcycle continued to roar, leaving a smell of gasoline on the 17th-century coastal plain, and it didn't take long for the motorcycle to plunge headlong into the humble Seven Bridges Pig Farm.

With a squeak, the solid tire of the motorcycle left a black scratch on the ground, and Huo Xiong rolled over and got out of the car.

Huo Xiong has dark skin and thick eyebrows, a face full of flesh, a tall and strong body, a motorcycle jacket is tightly worn by him, with a pistol on the back waist and a dagger behind the boots, the villain is full of momentum.

However, no one could have imagined that the real identity of such a living biker party was a 985 biology graduate student of Shandong University.

Looking at the three men, one woman and four pig farm workers standing trembling in front of him, Huo Xiong angrily threw the iron cage containing the piglets over: "What about the corpses? ”

"In the backyard!" The one who hurriedly took over the iron cage was a man in his thirties with a bitter face. This man's name was Yamane, and he was the head of the pig farm - he was in charge of his wife and two other employees.

When Huo Xiong heard this, he pushed aside the roots of the mountain, strode around the backyard to take a look, and suddenly became angry: there was a second senior brother with four black hairs lying neatly on the ground.

"Didn't you say three-headed!?" Huo Xiong turned his head, with an unkind expression.

"Fang... Fang just fell down again, just before you entered the door. ”

"Am I a plague god?" Huo Xiong couldn't speak when he heard this, so he immediately became angry and kicked over.

After seeing that Shan Gen, who had been prepared, deftly dodged, Huo Xiong snorted coldly: "Bring a knife." ”

Yamane's wife, a short, dark-skinned woman, lowered her head and handed Huo Xiong a pig-killing knife. After holding the knife and snorting coldly, Huo Xiong turned around and squatted down and began to dissect the four black pigs.

In fact, there is no need for a large dissection. The skin of the four dead pigs appeared purple spots, there were bleeding spots at the root of the ears, abdomen, inner thighs, and eyelids, the pig's intestines were rotten, and the pig feces were also bloody...... It didn't take long for Huo Xiong to determine the cause of the second senior brother's death: classic swine fever.

Standing up and patting his forehead, someone knew that some were busy now.

"How many are still alive?"

"Three-and-a-half-headed ones are raised in separate columns."

"It's also a column, a fart column!"

Huo Xiong said as he went to the pig pen and carefully examined the three sub-adult pigs that were still alive.

"Hurry up and move these heads to the backup point."

"Yes! Master. ”

......

Swine fever, also known as "swine cholera", is an acute, highly contagious virus that usually spreads between pigs and has no direct harm to humans.

In later generations, the vaccine against classical swine fever can be immunized for more than one year, and it is recognized as a attenuated vaccine with good safety, superior immunogenicity and stable hereditary.

But the traversal doesn't have that stuff.

Not only are there no vaccines, but there are no antibiotics and drugs commonly used in veterinary medicine - a force that is trying to climb the sulfonamide technology tree, and there is still a long way to go before antibiotics and vaccines are available.

There is no way, it has been less than two years since the forces crossed to this plane, and there is no time to build these branch technologies.

Therefore, Huo Xiong, who is the leader of animal husbandry, must find the source of infection today, otherwise, it will be a bad thing if it causes a large-scale swine fever.

So he took up his knife and began to dissect the dead pig on the ground a second time. Take a hundred plating on the latest chapter of "Luming Claw Book House" to read it for free for the first time.
