Ye Qing's plan was that the platform of the base was piled up about four meters high.

This height is a common height in the terraces of Luguo villages, and it is enough to defend against possible floods.

In terms of area, Ye Qing's plan seems to be larger than this era.

There are scattered village terraces on the Lu Country Plain, with a general area of ​​three to four hundred square meters, that is, a soil terrace with a length of 20 meters and a width of about 15 meters, and five or six thatched huts can be built on it.

According to the area of ​​the top surface of the platform, Ye Qing’s plan is to be 100 meters long and 50 meters wide, which is 5,000 square meters.

This area is about the same size as the platform where the great witches of Lu Kingdom live.

Ye Qing believes that after the establishment of a stronghold, it will inevitably become the center of this area, with the flow of people and cargo passing through, and the scale of the land will inevitably be quite large. If the place is not large enough, it will not be able to move.

Even with such a large area, he still felt a little small.

This area is not as good as the area of ​​a football field.

However, considering that there is a need in the later stage, it can continue to expand, so Ye Qing will just leave.

A great witch from Lu Kingdom was very surprised when she learned the size of the platform of the stronghold.

This size is about the same size as the platform where he lives.

He asked Ye Qing curiously:

"How many years will this stronghold be built?"

The platform where he lives has a history of more than a hundred years. Although the specific situation is not clear, he still knows the general situation when he was built after accepting the inheritance of the Great Witch.

Back then, in order to build this platform, the entire Lu Kingdom participated.

At that time, there were not as many people in the country as Lu, and not all the young and old were present. However, each household also had a young and strong laborer, with a total of more than 1,000 people.

It took more than a thousand people to build this platform five years.

Now, there are only 200 strongholds with a size of similar size, so how many years will it take?

Ye Qing was speechless about the questions of the Great Witch.

How many years have it been?

How is that possible!

In terms of time concept, Ye Qing is completely out of touch with this era. For modern social animals that measure time in hours and minutes, year is a huge unit of time.

Ye Qing sighed and sighed when he did anything slightly bigger to the people of this era.

Working is based on years and life span is short. So, how many things can a person do in his life?

Weave a piece of cloth a year...

Grind a jade piece in your life...

Generations have built a habitat...

Build a city in hundreds of years...

Such things are common phenomena in this era.

Ye Qing said to the Great Witch seriously:

"You should ask how many days it takes, not how many years it takes! I guess it will take about 20 days to build it."

The construction site of the base has a slope. Because there is a terrain that can be used, it is not completely accumulated on the flat ground. The total amount of earth is actually only about 20,000. 200 people spread it out, with more than 100 earthworks per person, and each person has five earthworks per day, which is almost the same for 20 days.

"Twenty...days?"

The witch was so shocked that she opened her mouth wide and couldn't close her mouth.

In his impression, such a large project never counts time in days.

It was built by 200 people, and he felt that twenty years were about the same.

"Yes, twenty days!"

Ye Qing said affirmatively.

This is the power of advanced tools.

The great witch was silent. He was already in his thirties. He thought that the stronghold was built, and it was the matter after his death. At that time, even if the stronghold infringed on the interests of his descendants, it had nothing to do with him.

After I die, no matter how floods it is, it is enough to enjoy the benefits brought by silk reeling technology when I am alive.

But now he found that Chinese people will only raise silkworms on a large scale next year, and silk reeling technology will benefit a lot next year, and the strongholds will infringe on their interests and will appear this year.

He regretted it a little.

He came to the construction site and watched carefully.

Yesterday, the main task was to build roads.

A circle of flat and wide roads have been built on the outer periphery of the platform foundation with a white line. On this road, carts have been traveling back and forth.

The place where the soil is taken is a small soil slope next to it.

A considerable gap has been dug out of the soil slope.

Dozens of people from Youlu who were swinging bronze pickaxes were digging hard.

The golden pickaxe was swung high and fell heavily. The sharp blade of the pickaxe was deeply immersed in the soil. Then, the handle of the pickaxe was gently lifted, and a large piece of soil was dug down from the slope and scattered all over the ground.

Although the great witch had not dug the soil himself, he had seen a lot of it by building a platform to dig soil to extract soil.

When Chinese people dig soil, they use stone adzes. If they want to dig so much soil, they have to wave the stone adzes for at least dozens of times. The stone adzes are too small and thick. With the same wave, they can only be buried in a shallow layer in the soil.

In other words, digging with a pickaxe is equivalent to digging dozens of times with a stone adze.

This does not include the polishing and loss of the tool.

The bronze pick head is almost impossible to damage, while the stone adze needs to be polished frequently or even replaced.

Stone tools are easy to break.

Behind, the people of Youlu who were holding the shovel gently inserted the shovel into the piled loose loess, then stepped on the shovel, easily shoveled up a shovel of loess and poured it into the carriage parked beside him.

The two people who shoveled the soil soon filled a cart.

If you change it to a bone trowel and shovel the soil, how long will it take to fill this car? The big witch can't estimate it.

The bone horn is made of the scapula of a large beast. Although the scapula is a large bone, it still looks very small when used as a tool. The amount of soil shoveling at one time is not much greater than holding it with both hands.

It takes about a dozen strokes to use a scoop of soil for a bronze shovel.

After the cart was full, the Lu people who pulled the cart after resting for a while, put a rope on their shoulders, held the handlebars with both hands, bowed slightly and dragged the cart.

The cart went all the way, without any pause.

It was easier for him to drag the cart of soil than to carry a load of soil.

The great witch silently estimated.

If you carry a load of soil with a basket, it will cost at least twenty loads.

In other words, with a chariot and transporting soil, a person can do the work of twenty people before, and it is not as tiring as carrying loads.

And tamping is faster.

The two of them carried a device that he couldn't understand, put it on the floating land, and stepped on the foot, and the wooden hammer on the device was lifted high. After rising to the top, they fell down with a bang, and smashed firmly on the ground.

Step on it again, smash it again.

After a few times, the ground became solid.

Then, the two of them carried the device and moved their positions slightly, and continued again.

And these two people were relaxed and sweating.

Ramming is the most tiring task, but under this kind of device, it has become the easiest task.

Looking at the entire process of digging and transporting soil, the Dawu finally concluded that the 200 people working with Fengfang tools were Lu people, and the work was more than ten, twenty times more than 200 people, which was equal to 3,000, 4,000, or even 5,000 people in the past...

Therefore, the base ground platform was built in 20 days, and it seems...it is OK.
Chapter completed!
