Why do things that cannot be done or cannot be scaled in the short term?

Of course it is to solve problems and make reserves.

The warriors of the old Lu family have completed the tribute. They are recruited again this year and are to be "public".

The group of warriors who were not recruited were ordered to be recruited.

The physically strong people are selected and they will become a new group to train in heavy infantry.

The premise is that Lu Wu personally trains them to teach them how to correctly be a "Jingluo".

In fact, the training of heavy infantry is not complicated. It is just a strong body that can sustain it and increase strength and endurance.

As for how to use weapons, it is the last thing.

Lu Wu had long discovered a situation.

People today generally have more endurance than those in later generations, and are more focused when training.

In terms of endurance of the ancients, they simply did not have the transportation tools they could choose; warriors were given physical work and self-discipline training.

Modern people have too many choices of transportation tools. Moreover, with the advancement of technology, the physical work needs to be done has decreased. More people sit almost all day long and do not do any physical work.

In general, unless modern people are special in their profession, most people really don’t have to spend their energy for a long time.

In this way, it is understandable that modern people have deteriorated in terms of strength and endurance?

The seriousness of warriors during training is mainly because they know what their profession is. Not taking training seriously is like joking about their lives.

Nowadays, soldiers go to the battlefield every year!

Due to the different times and the fact that the warriors have been fighting on their own, they soon entered training in the use of weapons and armor.

When Lu Wu asked to set up a formation, they were not unfamiliar with the dense formation and could quickly complete the formation composition.

Holding a sword in one hand and carrying a shield in the other hand is not a complicated behavior no matter how you look at it. It can be done with normal intelligence, but what tests strength and endurance.

The people of Jin have their own pursuit of discipline. If they don’t just become warriors, they can quickly understand every instruction and complete something according to the instructions.

The early training progress was too fast, which made Lu Wu feel that he could quickly form combat effectiveness.

Later, he found that he was still a little too optimistic.

The Jin people are familiar with the fighting style of dense formations, and they encounter difficulties when they wait to form the "tortoise shell formation" to advance layer by layer.

Things that require teamwork, once an individual makes a mistake [www.biqugex.biz], it affects the local area and spreads to the whole world.

They just put the shields together and formed shields on all sides. One person fell down and tripped the rest of the people, and the formation was disintegrated.

Training is like this. Once you enter the actual combat, the situations you encounter will be more complicated.

Why do the army need training?

Isn’t it just to correct mistakes that will be made again and again to avoid these mistakes?

Lu Wu did not act too impatient.

He asked Song Bin to take over the training, and he went to work on other things himself.

The cableway of the Lao Lu family has been built and the speed of transporting bricks is much faster than before.

The 20,000 labor force used to dig sewers has been in place. They go to their respective locations according to the allocation, shook their arms and sweated.

Lu Wu would patrol every day to check the project progress and check whether the specifications meet the requirements.

Pure physical work, don’t need to have too smart brains.

As a group of people who sweat, they can take care of what they should do and don’t have any ideas.

It can even be said that rigidity is the rigid requirement.

To be honest, even though there are "standards", it is the most undesirable to be smart.

What is the soil quality here?

The shallow part is mud, and the sand layer is not dug down.

However, some sense of age can be seen from some levels.

In fact, there will be a coverage level in every place.

For example, a certain place used to be a riverbed. Once it is covered and dug again, the soil in the deep is different from the shallow ones.

If you dig a certain mountain, you can see the layering of the soil more clearly.

Just like digging a water well, the most troublesome thing about digging a sewer is that it will cause water to come out once it is digging deep.

Although it is troublesome to have a water supply, it is considered good luck if you don’t dig the underground river.

After half a month of homework, Lu Wu found that his prediction seemed to be wrong?

It's not that it's slower, but that the progress is much faster than expected.

This is because Lu Wu "invented" too many tools, and these tools are pig iron products.

Are there any standards for human progress?

There must be some.

What kind of tools are used is a proof of progress.

To increase productivity, the role of tools is particularly critical!

Lu Wu will also take time to study coal.

He needs to experiment with some fragments in his memory.

A group of people were arranged to pick out the size of a fist.

Pure people have slow work efficiency and consume too much manpower. Lu Wu later provided creativity and was completed by craftsmen.

It is either a very high-precision thing, or a sieve that meets the requirements for selection of coal.

Today, Lu Wu needs to carry out the next step of evidence collection.

Fist-sized coal stones, they are placed into running water and are constantly flushed, and it is difficult to see any changes on the surface.

Because of this assignment, new problems arise!

Coal washing will produce a large amount of sewage. Once it is discharged at will, the first industrial pollution in the history of the earth will occur.

Lu Wu urgently stopped his homework.

He knew at least part of the environmental protection and ordered people to use bricks to build a pool for storing sewage, and used gradual filtration to filter impurities layer by layer.

Then, he found that layer by layer filtration was useless for coal washing wastewater at all. Heavier particles inside might precipitate, but there was also a kind of suspended substance in the coal slime that kept floating on the surface of the water.

Those things floating on the surface of the water are a kind of colloid. He tried to conduct static precipitation tests and found that they did not have much effect at all.

However, Lu Wu didn't know what to remove the coal after coal preparation. It was used as smelting and processing fuel, and the quality of the processed metal was surprisingly good!

Coal washing wastewater cannot be treated.

The quality of smelting metal is good?

This will be very uncomfortable!

Lu Wu is not a professional, he can only roughly understand the principles.

To put it bluntly, the raw coal is mixed with many impurities during the mining process, and the quality of coal is also different. The coal with small internal ash content and large internal ash content are mixed together.

Coal washing means removing impurities in raw coal.

He was troubled by industrial wastewater, but he could not control the temptation. He chose to use coal to make steel through the coal washing process.

Of course, because the coal washing wastewater cannot be treated, it is definitely not possible to do it on a large scale.

Lu Wu was thinking about where to find a place to build a large-scale coal washing base.

By this step, he had actually solved the problem of the inability to use coal from the old Lu family, and even opened a new "door", but the cost was a bit high.

Because of the lack of professionalism, he knew it had played a role, but he did not know that the coal selected and processed after deliberate selection and coal washing was called "fine coal".

Next, Lu Wu will continue to study the recycling of coal washing wastewater, but that is another course.

The old Lu family's own coal cannot be used on a large scale, but the smelting of metals requires a huge amount.

There have been teams transporting coal back from Lao Liang's house one after another.

Lu Wu personally conducted a verification, that is, compared the coals of Lao Liang's family with those of Lao Lu's family, and was surprised to find that there were still different open flames burning!

"Sulphur score exceeds the standard!" He was not professional, but he could see this, and showed a sudden look on his face and said, "Is this the difference?"

Maybe it was because the old Lu family went to get coal again?

Liang Qi came to the "yin" land with anxiety.

He knew that there was a big gap between him and Lu Wu in terms of identity, so he did not ask to see Lu Wu after coming, but was looking for Liang Xing.

Liang Xing, who regards eating, drinking and having fun as his profession, has his main task to socialize.

Liang Xing naturally could not contact the middle and big nobles, and the target of eating, drinking and having fun was their retainers.

As for the little noble, because of Lu Wu's repeated "value-added", Liang Xing, as a retainer of Lu Wu, formed a "equal" of identity with the little noble.
