In the fourth year of the reign of King Qin, the autumn equinox.

The crowds on both sides of Weishui were surging, a large number of Qin troops were stationed on both sides of the river, and more Qiantou were looking at the king of Weishui on the huge altar through the sergeants.

In these years, there is no TV and no mobile phone, and it is not easy to see the king.

Ying Zheng on the altar finished reading the sacrifice with a crown expressionless, and then solemnly threw it into the tumbling water.

Seeing this scene, Li Si under the altar immediately signaled the standard-bearer beside him to wave the flag.

In the fleet above Weishui, on the largest boat, Li Yunze saw the flags waving on the shore and nodded to the water ghosts around him.

After a short time, on the turbulent surface of the Weishui River, a black figure more than ten zhang long appeared from time to time.

The tos, who were arranged in the crowd in advance, immediately shouted when they saw this, "Look, the black dragon has responded to the king's call, look at the black dragon~~~"

At this time, the Weishui River was very wide, because there were no many reservoirs and other water conservancy facilities, and the water consumption was not as terrible as in later generations, so the widest part of the river was even as high as hundreds of zhang.

Many Qiantou leaders on both sides of the strait also saw the black figures churning in the Weishui, and the noise resounded in the sky for a while, and some even saluted in awe.

Especially when the huge faucet rushed out of the water, there was almost an explosion on both sides.

Ying Zheng on the altar, looking at the excited people through the crown hanging down from the crown (beads), but what he thought in his heart was, "What a foolish thing to do, where is there a fairy black dragon, it's just the application of mathematics, physics and chemistry, this is the power of science!" ”

If you don't believe in immortals and don't seek immortality, at least now you don't believe in it, and there is unprecedented pride in your heart.

You don't understand what the few understand, this is the power of knowledge!

The appearance of the black dragon in Weishui directly put King Yingzheng of Qin on the altar.

The people of Qin all believe that their king is a king favored by the heavens, and even the black dragon can be summoned anytime and anywhere.

In modern terms, it's 'King Cow Beep~~~'

A Qin king who is not superstitious, but believes in mathematics, physics and chemistry, is an inexplicable existence in this era.

The sacrifice to Weishui is naturally not for nothing, the reason is that after several years of famine, this year's Daqin finally obtained a rare harvest.

During spring ploughing, thanks to a large number of tamed oxen and the use of quyuan ploughs, the Qin people burned large areas of forests, drained many swamps and lakes, and reclaimed many new fields.

The people use a lot of cocoons, deep ploughing and deep planting, coupled with the combination of chemical fertilizers and water conservancy, the corn growth in the growing season is gratifying.

When it came to the autumn harvest, thanks to the improvement in the production and quality of steel, the people of Qin were able to use sickles on a large scale to harvest, and the efficiency was greatly enhanced, and the final result was that much more grain was harvested than in previous years.

With food, the Qin State, which had eased up, finally began to use troops to the east.

King Yingzheng of Qin worshiped the general Meng Fu as a general, and led his troops to attack the Wei state that killed Xinling Jun.

The Qin State, which sent troops this time, not only brought tens of thousands of new cavalry, but even transported twelve Qin King cannons over!

With the blessing of King Qin's great ritual weapon, Meng Fu's offensive can be called a blow and decay.

Those Wei troops who did not dare to fight with the Qin State and chose to hide in the city to defend the city were considered to be unlucky.

More than 20 cities, such as Sujube City, Yancheng, Xucheng, Taoren City, Yongqiu City, etc., were blasted open in the roar of the Qin King's ritual vessels, and fell into the hands of the Qin army with a sad cry.

Ying Zheng set up this large area of newly acquired land as a new county, which was called Dongjun.

If you are not familiar with the place name, you just need to know that this is the area of Jiaozuo Puyang.

After this war, the already declining Wei State suffered a devastating blow, and its national strength fell to the level of being on a par with South Korea.

Such a collapsed performance really made the Wei soldiers of the year ashamed.

There is no way, the Wei State was rampant during the period of Wei Wushu, and later fell into internal strife and generations of faint kings.

Just like to seize power, King Wei knew that Wei Wuji, the king of Xinling, was the last famous general of Wei, but he must also force him to death.

Without the commander of famous generals and foreign assistance, he couldn't even defend the city, and the decline of Wei was a matter of course.

During this battle, Qin's great ritual weapons attracted the attention of various countries, and countless secret agents were sent to Qin to inquire about relevant information.

It's just that the Qin people did a good job in this regard, and under the even sitting system, most of the spies were taken down before they could reach Xianyang City.

The only one who can really know a little bit about the details is Yan Guo.

When Prince Dan learned what happened to Wei, he was also worried.

He knew very well that once the Qin army took Dagui to the Yan Kingdom, no city would be able to withstand it!

Prince Dan secretly swore to himself, "You have to find a way!" ”

When Xianyang City was secretly turbulent, Li Yunze was giving Yingzheng a lesson.

"You have already learned about the frame structure, today we will focus on the bearing"

"There is a very important way to apply bearings, and that is the steering structure"

"And the most important application of the steering architecture is the new horse-drawn carriage."

Li Yunze took Ying Zheng to the warehouse, stretched out his hand and gestured to the frame chassis in front of him, "This is the core component of the four-wheeled carriage." ”

Horse-drawn carriages have been around for a long time, but they are all two-wheeled.

Compared to a two-wheeled carriage, a four-wheeled carriage is not only smoother, but also carries a greater weight for transportation.

There is no doubt that this is certainly a technological advancement.

Ying Zheng walked around the frame chassis a few times with great interest, asked about the parts one by one, and combined the knowledge he learned to understand the principle.

Next, it was arranged for the entire carriage to be assembled by hand, and then dragged forward by a pack horse.

Seeing the four-wheeled carriage loaded with a large amount of goods moving quickly and moving flexibly in a different direction, Ying Zheng was overjoyed, "In this way, the efficiency of transporting grain and grass to the front line will be greatly increased." ”

"Yes, that's it."

Li Yunze did not mention the role of the four-wheeled carriage in the field of civilian transportation, because Yingzheng was most concerned about the military field.

In fact, even in the First World War, horse-drawn carriages were still the most important transportation force in the army.

"This Wheel"

Ying Zheng carefully looked at the width of the wheels, and said with a little doubt, "It seems to be wider than the wheels of a two-wheeled carriage." ”

"That's right."

Li Yunze on the side explained, "The wider contact area helps to maintain stability, in fact, I also want to wrap a layer of gum on the outside of the wheel, but the yield is too low." ”

Gum is somewhat similar to rubber, except that the yield is much lower than that of rubber.

In addition to gums, there are also some herbaceous plants that can produce gum, but they are all the same problems, with low yield and low quality.

As for going to South America in search of rubber trees. In terms of navigation technology in this era, it is better to wait until after the Qin State destroyed Chuding and Nanyue, and Li Yunze directly transported a batch from the modern world.

Ying Zheng asked again: "Is it the same as Daqin's current track?" ”

Li Yunze immediately shook his head, "It's a lot wider, mainly to be able to load more goods." ”

After the book was written in the same article, Li Yunze began to arrange the matter of the car on the same track.

The so-called same track refers to the fact that the tracks of different widths are summarized and sorted into the same standard.

Trains can only move fast when they have tracks, but tracks don't appear after they have trains.

In fact, during the Warring States period, the use of orbits was very extensive.

Basically, many roads were built to connect cities to transport supplies.

A large number of horse-drawn carriages travel on the gallop road all year round, and after repeated crushing, the original dirt road has been crushed into two hard lanes with the width of the wheels.

Horse-drawn carts carrying supplies are as smooth as they keep their wheels on hard lanes, significantly reducing animal power consumption and axle wear, just like a modern vehicle on an asphalt road.

And these two hard lanes are the tracks of this era.

The spacing between the wheels of horse-drawn carriages is different in different countries, so the width of the tracks rolled out is naturally different.

When Qin went out to fight, he suffered greatly.

Because of the different wheel widths, the wheels of Qin's carriages could not be on the tracks of other countries, which seriously affected the ability to transport materials.

After all, they are all dirt roads, and after the wind and rain, except for the two hardened tracks, the other roads are equivalent to scrapping and cannot be used.

In order to solve this problem, the Qin people built their own tracks, using wood to build transport tracks similar to those on the side of modern train tracks.

In order to maintain stability, sleepers were laid under the wooden tracks!

It can't be said to be exactly the same as modern train tracks, it can only be said that it is eight or nine and ten.

"My lord, how effective is this four-wheeled carriage?"

"Good."

"How is it better than the previous two-wheeled carriage?"

"Better."

Li Yunze finally said his thoughts: "Since this is the case, then take the wheel width of this four-wheeled carriage as a quota, and change the track standard of the whole world to the same, how about the same track from now on?" ”

Ying Zheng nodded, thinking that what Li Yunze said was very reasonable.

Here, Li Yunze's words were not finished: "In the future, wherever the Qin army fights, the standard track will be repaired." Especially in the Western Regions, along the Qilian Mountains all the way to the Tianshan Mountains, you can quickly mobilize materials and personnel, all the way to the west! ”

As for Li Yunze's strategic proposition of going all the way to the west, Ying Zheng also agreed.

He also wants to be the captain that Li Yunze said.

It's just that instead of fighting to the west, Yingzheng wants to destroy the Kwantung countries first.

The car on the same track is beneficial to the Qin State, because now it is basically the Qin State sending troops to fight in other countries, so it was quickly approved and supported.

As for the track standard, it is somewhat controversial.

The reason is very simple, the tracks in the Qin State are now built with the distance between the wheels of two-wheeled carriages, and if they are changed to four-wheeled carriages, it means that all of them will have to be rebuilt.

It's a huge undertaking.

At this time, Ying Zheng showed his courage.

He said, "Now the use of two-wheeled carriages is to save effort, but the benefits of four-wheeled carriages are even greater." For the long-term plan for the future, it must be changed! ”

With the support of Ying Zheng and Zhao Ji's seal, the matter of the car on the same track was finally passed.

Obviously, the conscription of the Qin people is going to increase again.

The so-called forced labor, which means providing one's own dry food to work for the state for free, is undoubtedly a kind of tyranny.

It's just that this era is like this, and there is no way to do it.

Li Yunze also made a contribution, that is, to promote brick burning.

Using bricks to repair the track can save a lot of work and trouble.

Similarly, the large-scale use of bricks has a huge role in promoting the construction of cities and houses.

When Great Qin was busy building brick kilns in various places and reorganizing the tracks, the Kwantung Kingdoms, which paid close attention to Qin, also built their own Dagui one after another.

The problem is that their Dagui ritual vessel is really a ritual vessel, because there is no gunpowder!
