Those central thieves who went all the way to the end of the road were really rat traps and didn't dare to catch up.

The remaining small half of the roasted crane has long since cooled down.

Zhao Yanqing was a picky eater and hated the cold taste. I'd rather starve to death than eat any more. Wu Song was determined not to have another fire to roast it. So this Yu Lori was so hungry that she was dizzy, and she didn't have the strength to scold the two untouchables around her. Groggily, he leaned on Liang Hongyu and fell asleep.

In fact, the weather is dry in summer, and the yellow mud ground is dry and fluffy, so you can sleep underground.

But this little princess is very hypocritical, and will never sleep in the yellow mud. In fact, she can also take a nap on Wu Erlang's lap, but she is extremely hostile to this evil bandit. is only willing to sleep on Liang Hongyu's body.

After all, it was Li Qingzhao's family, and the sanitary situation was reassuring.

After all, it's a slave. Slaves and maids were supposed to do that. You must know that many landlords can't tolerate the cold quilt in winter, and they usually use small maids to warm their beds. It's a tradition that has been around for thousands of years.

This is in line with the laws of heaven.

Zhao Yanqing herself is a girl. She knows a little bit about physiology. Sister paper is a creature that is warm in winter and cool in summer. The effect of the servant girl warming the bed is much better than that of the servant. Sister paper secretly thought about something embarrassing in her heart, and suddenly her whole body was hot. This proves that when Pangu opened the world and Nuwa created human beings, she had already delineated the talent attribute that sister paper was most suitable for warming the bed.

Since sister paper is a natural commodity used to warm beds...... Zhao Yanqing has always believed that he is a golden branch and jade leaf, and temporarily used this little maid in Li Qingzhao's family as a mattress, which actually promoted her and gave face to the Prime Minister's Mansion.

So Zhao Yanqing fell asleep groggy, half of him was hungry and faint, and half of him was really tired. Along the way, Wu Song used a wicker to drive the two little Loli all the way, and he was already tired.

This made Liang Hongyu unable to sleep.

She leaned her back against the tree, half leaning under its roots. But she held the little princess in her arms, as if Zhao Yanqing was her daughter.

Wu Song couldn't stand it a little, and persuaded this red jade girl to be ruthless, take advantage of this Yu Lori to be confused, move aside, and forgive her for not waking up. In this way, Liang Hongyu herself can also seize the time to sleep for a while.

But Liang Hongyu shook her head and rejected the suggestion kindly put forward by Second Brother Wu.

Wu Song did not continue to force.

I went to the other end and fell asleep with my head in my arms.

Wu Song has been in the rivers and lakes for a long time, and he does not sleep deeply, so he is very vigilant. If there is any disturbance, you can wake up immediately and respond in a timely manner.

Unexpectedly, there was nothing unusual about this night, and it was spent peacefully.

I slept peacefully until three o'clock.

The time has not yet come, and the sky is not clear. The male cranes in the reeds made one after another the chirping of Qingyue cranes.

The crane is actually not much different from chickens, ducks and geese.

Just like a rooster crows and sings, the wild geese and cranes are usually the alarm clocks of the wild geese and cranes.

Of course, there is not even a clock in these years, let alone an alarm clock.

However, Wu Song had heard the comrades of the committee mention those things about the alarm clock. The alarm clock is said to be the easiest key golden finger to achieve by a traverser.

As an indigenous, Wu Song actually knows how to use the golden finger, which is a strange thing. This is actually due to the power of group wearing. Ten time-traveling criminals gathered together all day long to fiercely debate the development of the Liangshan Group and the way out, this kind of fierce debate, the ears heard a lot, and they vaguely knew many new concepts from different time and space.

Now Wu Song knows a few things:

In order to start the Age of Discovery in advance, the committee paid great attention to the operation of the golden finger of the clock. The soap finger, which was commonly used by the travelers, was rejected, and the gunpowder gold finger was placed in a relatively secondary position. Steelmaking gold fingers are greatly valued in advance.

The Commission considered that there was no point in developing arquebuses, that the charge was not large enough, and that in the context of the unreliable gunpowder process, the lethality was a mess.

Black powder gold finger can be had, although the blasting power is not very high, but it can be used as a cannon, although it is not up to the level of Napoleon, but it is enough to fight the local indigenous infantry. It is nothing more than a coarser one, a larger charge and a shorter range. Ditch grenades and solid bullets and focus on shotguns. The damage to the dense infantry array is considerable enough. It's okay to call it an artifact. It's just that the rate of fire and firing range of this low-level cannon are greatly limited, and I am afraid that it will not be able to resist the surprise attack from the elite cavalry.

That is to say, the large-caliber short-barreled bronze shotgun that Liangshan is secretly making at the moment is suitable for defending the city or guarding the dangerous stronghold of the cottage. On the plains, it will not be able to resist the onslaught of massive cavalry. After all, the firing range is too short, and the reload is too slow. In the face of a cavalry charge, there was only one chance to fire. The cavalry only needed to withstand the first wave of artillery fire, and the second group could easily break the formation. Once the artillery is close to the cavalry, it is a dish to be chopped.

Therefore, after several months of long debate, the 24-member committee of Yangshan decided to go to sea to seek development.

Industrialization is a long process. The sporadic gold fingers are of no use. In order to develop a self-consistent industrial system, it is necessary to have a solid and reliable independent base.

Such a base can undoubtedly only be at sea. The Navy's warships themselves were characterized by maneuverability and sluggishness, which solved the problem of slow loading of early shotguns. Warship to warship, there is no cavalry charge. The power of the shotgun can be fully exerted, and the slow reloading of the cannon for fear of being charged is also offset by the maneuverability and sluggishness of the battleship.

Going to sea is the established Yangsan program.

But the Yangsan Committee was in no hurry to go to sea. Because once you go to sea, it will be difficult to collect talents and skilled craftsmen. Therefore, the Liangshan forces in the early stage should have held out until the eve of the Fangla uprising. Use this time to grasp the resources and technology that can be used in the current environment as much as possible, and tailor a full set of industrial development plans for the Northern Song Dynasty.

The soap was rejected by the committee.

Because there is no soda ash and baking soda. As for the preparation of soda ash, that requires electrolysis.

As for power generation, this has to be talked about at two ends. In fact, if two electrodes are randomly inserted into the potato, you can get a biological weak electricity. But this weak electricity is so weak that even the electron tube can't be lit, and it can only activate the light-emitting diode. To electrolyze soda ash, silicon steel sheets and enameled wires are required.

Silicon steel sheet is nonsense.

This requires steelmaking.

Steelmaking...... This is white technology around 1800. Considering that black technology can be launched in advance of some low-quality inferior steel, in fact, this can be available now. It's just that the committee doesn't intend to toss this behemoth in Yangsan. After separating Penghu, Zhoushan and Taiwan's Ryukyus, he plans to build a large number of buildings on the island.

Steelmaking by soil method requires three props with little technical content: refractory bricks, thermoreverberatory furnaces, and thermal blowers.

Of course, acetylene can be prepared with calcium carbide, which is even more powerful. However, in these years, there are calcium carbide and acetylene, but there is no way to get acetylene into high-pressure cylinders.

The Great Leap Forward type earth kiln is the simplest. Although the steel produced was a bit of slag, not much better than wrought iron, the committee did not intend to build trains and dreadnoughts, and it did not matter if the carbon content was a little higher, as long as a large pot of molten iron could be smelted, and a large homogeneous iron pipe without bubbles and cracks could be poured by the casting method.

The maximum temperature that can be achieved by human brick kilns is 1000-1100 degrees Celsius, and the temperature required for steelmaking is 1350-1500 degrees. This bottleneck has stuck the necks of the world's people for nearly 2,000 years, and human civilization has gone through more than 1,2000 years of the Iron Age, and finally the British found a solution to steelmaking in the early stage of the industrial revolution.

First of all, you need refractory bricks that can withstand high temperatures of 1500 degrees. This Great Song China happens to be available. The lack of iron, copper, coal, sulfur and nitrate (lack of iron and coal refers to the lack of high-quality ores), but the least shortage is high-quality clay mines.

The reverberatory furnace is simple. It is nothing more than designing the hearth into all sorts of strange shapes, allowing the heat lines to focus back and forth on the inside. If you have seen the earth blast furnace of later generations, you can draw it according to your memory and imitate it. Although it is not accurate, if you try a few more and dozens of different details, you can naturally find the optimal solution.

The heat blower is a brainstorming technology. It's not very high-tech. The Industrial Revolution was the first to open this brain hole in the British, so they led the way to the world.

Brain hole technology is the most suitable for people to apply in advance.

Steelmaking requires high temperatures, and to create high temperatures, of course, it is necessary to vigorously blast air to deliver more oxygen to support combustion. The blower blows in the cold air, but it has the opposite effect of cooling down. At the same time, the air circulation also destroys the thermal cohesion in the high-temperature reverberatory furnace. The brains of the British were to build an adjacent auxiliary furnace and get the preheated hot air in. Originally, the high temperature required for steelmaking was not obtained, and it was only 300 degrees Celsius higher than that of ordinary small coal kilns. It's just right to put all of these means to use. Therefore, the members of the People's Commune in the era of the Great Leap Forward could also make steel.

This is a key project of the Yangsan Committee. However, there are no plans to start construction at this time. At present, it is only focusing on accumulating skilled craftsmen who can be used in related fields. and some small-scale lab-level trials.

The so-called skilled craftsmen are mainly in mold making and grinding and polishing.

This kind of talent requires a large number of reserves. There will be great uses in the future. During the Ming Dynasty, a cannon factory could produce several cannons a month, at most a dozen. It's stuck in the bottleneck of insufficient number of craftsmen.

The committee is going to sea anyway. The blast furnace is not in a hurry to build now.

However, pouring molds requires a lot of manpower and a large number of experienced masters.

The most important thing in the twelfth century was talent! It's about the reserve of this talent, so you have to plan early.
