On the vast plains outside the city, a sharp weapon breaks through the soil that has been precipitated for thousands of years.

The manpower quyuan plough drove straight into this unexplored Chu Nu land, and the deep soil rolled up the struggling and jumping earthworms.

A few children followed the plough and picked up the earthworms from the ground and put them in clay pots, which are the fish's favorite bait.

Before sowing, a deep ploughing was needed to loosen the soil, and the use of bronze farming tools was too slow, so Gu Guo and his clansmen simply made three quyuan ploughs that only appeared in the Tang Dynasty.

And the ox that acts as the power in front has not yet been fully domesticated in this world, so the tribesmen themselves went into battle, pulling one for every five people. Since the curved plough wheel changes the direction of traction, the clansmen pulling in front of them are at ease.

The three advancing cultivated land "cars" bypassed the landmark that Gu Guo had planted on the ground in advance, which was a farmland plot specially marked by Gu Guo, a square with a side of 50 meters, with an area of 2,500 square meters, about the size of 3.7 acres of land in the previous life.

After rough calculations, the harvest of the second generation of wild wheat planted on such a square area is about 300 kilograms at a time, which is just enough to feed one person for a year.

As a result, a new unit for measuring land and grain was created by Gu Guo - "Fen" and "Dou".

One person and one field are one struggle, and three meals a day are one bucket.

In another world, the word struggle has a whole new interpretation.

Almost all of the wheat sown in the field this time was the second-generation wheat that Gu Guo exchanged from the system, and a small part of the remaining was the first-generation wheat collected by Gu Guo again last year.

The harvest of the first generation of wheat is definitely not as good as the second generation after the second screening, and it is already very good to be able to plant 100 catties of seeds in a hard land (2500 square meters).

When the land cultivated by one person can produce food to support more than one person, it can be counted as a full-scale agricultural era.

The plough is very fast, a group of six people can plough about three fen of land a day, and the limit of a single plough is two fen of land, of course, intensive tillage and loose soil are not the same.

When the soil is loosened, all that is left is a clod the size of half a football ball, which needs to be broken up with a hoe, and the most important role of the curved plow is to quickly clear the land, not to cultivate it intensively.

Seventeen pieces of land of standard size have been reclaimed, and dozens of clansmen are knocking out the soil with bronze hoes.

After three days of hard work, the fields the size of six football fields were clearly furrowed, and the ridges were as straight as air canals, and the water in the canals was more than enough to irrigate the 64 acres of land.

As for why Gu Guo didn't reclaim more land?

There were only so many second-generation wheat seeds that he exchanged for all his contribution points, and they were gone after scattering.

Gu Guo was also very distressed why 1 point of contribution could only be exchanged for 1 kilogram of second-generation wheat seeds, obviously at the beginning of the system to explain that creating 1 ton of grain can get 1 point of contribution, but now it has shrunk a thousand times!

This damn profiteer system!

A year later, under the wash of rain and snow, the soil will harden into lumps again, and it will have to be reclaimed again the next year, but the gains outweigh the losses and waste labor.

At the beginning of the year, he traveled 2,000 miles south by boat, and Gu Guo had already seen the limit of the world's productivity. At least during his lifetime, most of the creations of the era of the First Industrial Revolution would not have been possible.

There are tens of thousands of people in the Tao River basin at most, and in the previous life, no country with only a few tens of thousands of people could develop a complete industrial production line, they all engaged in tourism, and even needed to import grain.

And the Bronze Age, where the congenital infrastructure was insufficient, let alone those roaring machines.

Want to make a steam engine? Okay, first allocate 1,000 people to build the steel mill, and then thousands of people to mine, manganese steel, chromium steel, high-carbon steel, low-carbon steel, all of them, and hundreds of people are needed to study the properties of metals, and then thousands of workers to build high-pressure boilers, cylinder blocks, crankshaft connecting rods, pistons, bearings......

In this way, the population of the Tao River valley was all allocated to the construction of a steam engine, and if this thing was to be put to work and put it on steamships and locomotives, it would take tens of thousands of steamers and railroad workers to serve it.

Industry is a complete system, the more complex the development of the direction, on this basis the investment of manpower is a geometric multiple.

In Gu Guo's previous life, the countries that were able to independently build and launch carrier rockets could be counted with both hands and feet, and all of them were large countries with a population of more than 10 million.

A complete industrial system is not a hammer in the east to build a lithography machine, and a hammer to fly a space station in the west, such a beautiful vision only exists in novels.

It took Gu Guo more than half a year to build a waterwheel, a sailboat and a canal, and these three things could not be mass-produced, and the goal of industrialization was to mass-produce those most advanced products.

Want a second sailboat? Then it will take another half a year to build one, instead of spending a few days welding the steel up and down the assembly line.

What are tens of thousands of people enough to do in the Stone Age? At most, the prototype of the country was developed, and the Iron Age of the castle sword and shield was entered.

Gu Guo felt that he was already standing at the top of the world at this moment, overlooking the limits of the lives of all living beings, the limits of human productivity in this world.

"In a few years, when the yield per mu of all wheat reaches two hundred catties, it will be the time when I am invincible in this world!"

Gu Guo said this sentence arrogantly.

And at this moment, along the rivers of the world, those who were thrown into this world by Gaia, some of them became gods worshiped by thousands of people, and frantically plundered the surrounding population as labor; Some people are still hungry and full, indulging in many-to-many warm nephrite......

Only a few traversers like Gu Guo released similar lofty ambitions after exploring the surrounding thousands of square kilometers of land.

"天は人の上に人を造らず,人の下に人を造らず." (Heaven does not create a man, nor does it create a man)

“Formez vos bataillons! Marchons， marchons!” (Get the team organized!) Rise! Endeavor! ）

“Служитьвеликимцелямвремени-вотчтобессмертно。” (Serving the great goals of the times is immortal.) ）

The world of the earth is so vast, and countless bifurcated timelines have developed on top of it, and in the countless long rivers of history, there will always be no shortage of those advancing ethnic individuals.

Now that he saw the limits of what he could develop before he died, Gu Guo naturally had an urge to surpass him.

At least you can't stay in the Bronze Age in these decades, and no matter how hard you don't fight, you have to touch the threshold of wrought iron.

The industrious cause of the tribe has been planted, and they are waiting for the autumn to harvest the sweet fruits of wheat.
