In the next few days, Liu Che focused most of his energy on climbing the science and technology tree, except for the previous court.

It has to be said that the gap between the emperor and the crown prince is almost calculated in light years.

When Liu Che was still the prince, he could only carefully dig the foot of the Shaofu and secretly engage in technology research and development.

However, after becoming the emperor, he can play as much as he wants!

All the resources of the entire Shaofu are all open to him!

Shaofu has tens of thousands of registered craftsmen, and although these craftsmen may not be educated, they have been craftsmen since their parents, grandparents and even great-grandparents.

With only experience and hands, they were able to create a variety of devices with complex structures that could only be manufactured with precision instruments in later generations.

In Shaofu, there is even black technology - the gold-plating technology inherited from the Qin Dynasty!

These craftsmen used methods that Liu Che couldn't understand, and forcibly plated a layer of rare metal on the steel and bronze swords.

Weapons plated with this metal will immediately gain a special effect - it will never rust and sharpen iron like mud!

The metal they plated, according to Liu Che's memory, should be the chrome-plated weapons unearthed together with the Terracotta Warriors and Horses of Qin Shi Huang and shocked the world.

Liu Che didn't know much about metals, but he remembered that it seemed to be said on the news in later generations that this kind of chromium is a rare metal on the earth, and the content is very small, and most importantly, it needs a high temperature of 3000 degrees Celsius before it melts!

In later generations, it was not until the thirties of the twentieth century that the West mastered the technology of chromium metal.

But this kind of black technology. The actual meaning is not much......

Because, this chrome sword. The yield is extremely low!

At the end of the year, Shaofu can successfully chrome two or three swords at most.

And these swords. It is generally used as a sword for the Son of Heaven and as a funeral gift when the princes and kings die.

Basically, it will not flow into the army......

But from this point of view, this era is not completely a scientific desert.

At least, this is not the case in Shaofu.

And with Liu Che's ascension to the throne as emperor, Shaofu has completely become his own toy.

The tens of thousands of craftsmen, the huge group of workshops, and the endless wealth and manpower are all owned by Liu Che alone.

In such a situation. As soon as Liu Che gave the order, the entire Shaofu moved quickly according to his wishes.

In just a month, the first steel-making blast furnace on the earth before the Common Era was erected in a remote corner of Shanglinyuan.

The blast furnace is actually not very high, at most only three meters high.

It is made of clay and masonry.

From a distance, it looks like an ugly little tower.

It uses coking coal and coke as fuel, and 'steelmaking' is carried out day and night.

At present, at least 500 catties of pig iron can be turned into corresponding 'carbon steel' in one day.

It's just that the quality is worrying. It is difficult to guarantee the quality of the molten steel that comes out.

Moreover, the energy consumption is extremely high, and the pollution is also very strict.

Besides. There are no drawbacks.

Anyway, when Shaofu Ling Cen Mai saw this ugly thing, he could really make steel.

Happy like a child. He has already decided, in a year. Build 500 such steel-making furnaces, and strive to produce 100,000 catties of steel within the year!

As for environmental pollution or something......

I want to develop industry. How can it not be polluted?

After the British Industrial Revolution, London almost became a hellish city, and the Thames River was said to be dead even shrimp and bugs!

At the same time, Paris, France, was known as the stinky ......

But Liu Che didn't agree to play like this in Guanzhong.

First of all, there is no iron ore in Guanzhong itself, and secondly, if Guanzhong really becomes a place of black smoke and miasma, and the smog covers the sun, Liu's country may not be sitting for long......

Therefore, Liu Che was inclined to put these blast furnaces in the main coal and iron producing areas such as Shu County or Hedong.

In addition, hydraulic forging technology has also begun to make breakthroughs.

The first waterwheel has already been installed in Shanglinyuan and is expected to be put into use before spring ploughing.

The successful research and development of the waterwheel means that the hydraulic forging technology has entered a critical moment, and the emergence of cuirassiers has begun to enter the countdown.

In addition, soil cement has already been successful and put into use.

At present, this kind of cement is mainly used to pave roads for the imperial palace, especially the royal roads where the empress dowager often goes.

If Tufa cement wants large-scale mass production, it still needs to go a long way.

Now, Liu Che began to set his sights on orbital transportation.

Under his orders, a wooden track began to be built in the Sixian Garden of Shanglin Garden.

The technology of the track is readily available.

Back then, Qin Shi Huang used this technique in order to eliminate the state of Chu.

The Qin people built many rail transit networks on the Qin-Chu border.

This kind of track, powered by horses, has a rather special design, so that the horses will always run unconsciously on the track.

As a result, supplies can reach the front line quickly and quickly.

According to the records of the Qin Dynasty preserved in Shiqu Pavilion, this kind of carriage track could deliver materials to the front line hundreds of miles away in one day and night.

It was with the help of this rail transit network that the Qin people quickly destroyed the state of Chu and entered and conquered South Vietnam.

However, with the fall of the vast Qin Empire in a peasant uprising, the nascent Han dynasty, in its early days, was short of horses.

Back then, even Liu Bang himself couldn't find five horses of the same color, and the dignified prime minister Xiao He actually rode an ox cart to the court......

In that case, many of the Qin Dynasty rail transit networks that were preserved in the war lost their role.

It was either demolished or ordered to be landfilled.

Because, this kind of track, only suitable for horsepower transportation.

When the Han dynasty lost the Hetao area and had no source of horses, this kind of track became a burden.

Its existence zài, i.e. obstructing traffic, does not yet have any effect!

It's just that Xiao He, the prime minister who ordered the demolition and burial of these tracks at that time, was extremely far-sighted, and he ordered that an entire track of the Qin Dynasty be completely dismantled and then stored in the arsenal.

In addition, all the technical data and construction drawings of the entire track are sealed in the Shiqu Pavilion for the future.

Today, the wooden rails used in the track laid in Sixian Yuan are completely reproduced in accordance with the materials and drawings preserved by Xiao He, and compared with the wooden rails in the sealed Zài arsenal.

It's just that this kind of wooden track costs a lot of money, and the cost of each mile is as high as fifty or sixty thousand yuan.

If you want to lay a track from Chang'an to Xiaoguan, it will cost at least tens of millions of money.

Moreover, it is extremely easy to destroy - it can be cut off by a fire.

In addition, since it is transported in horsepower.

Therefore, the horse stations along the way, as well as various nursing staff, need to be trained and built.

However, it is the most convenient, fastest, most efficient and most powerful mode of transportation of our time.

Because of the special wooden rail design, it is difficult for the horse to stop when running on such a track, and there is no need for the driver to whip it......

And a standard rail carriage can deliver thousands of catties of materials to the places where they are needed day and night.

For war, this is almost a key condition that determines victory or defeat!

Only the Qin people would have invented and created such a sharp transportation technology.

After all, the Qin State had a small population, and during the War of Unification, almost all of his young men joined the army.

Without such technology, it is difficult for him to have a quick supply.

A month later, when Liu Che saw in Sixian Garden, on the track that had been completed, two horses, pulling several carriages, galloped wildly on the track with the momentum of a steam train.

He decided to start laying the track between Chang'an and Xiaoguan.

If nothing else, just after having this track, once the Huns invade again, Chang'an's troops and supplies can arrive at Xiaoguan in a day and night to participate in the resistance.

This will play an extremely important role in the military!

What's more, this kind of rail transit will also greatly enhance the commercial economy of the Han family.

In comparison, what seems like a huge investment seems to be worth it.

"Go and ask Zuo Xiangguo and the lieutenant to come over......" Liu Che turned back to Wang Dao, who was already frightened by the track, and ordered: "Let them take a look, this kind of track ......"

Liu Che dared to pack the ticket, and Zhou Yafu and Zhi would definitely support his decision. (To be continued......)
