April 2130.

Cao Chuan walked out of the spaceship, followed by 3 loli.

Planet 6, which is no more than 25 astronomical units apart, is unknown.

Such a big contrast, even if he is a perfect life, what if their spaceship is the most advanced spaceship of human civilization?

Cao Chuan looked excited, not worried about the future at all, 3 Loli wandered around, the new earth is really very comfortable, pleasant temperature, humid air, soothing color, it seems to be a fairyland on earth.

"It's worthy of being the star of life..."Cao Chuan sighed after half a day, "Shouldn't we do something... At least build a base, otherwise, I don't know when I'll come over..."

"Of course, master, you're right, hurry up and get to work." Nana replied, and they began to cooperate, first launching the satellite, opening the map of the planet, and then the four joint production workshops were moved out and reassembled.

Directly in the open air, the joint production workshop looks a little primitive and rough, but who said that the environment of the new earth is better, and there is no need to hide underground?

Then they drove mining vehicles, engineering vehicles ran around, resources, energy replenished one after another, a week passed, a 10,000 square meters of base construction was completed, there are already 1,000 unmanned units in the activity.

The basic and preliminary construction has been completed, and it is not a problem to say that daily life is not a problem at all, because the population of the base is only 4, and the consumption of food, clean water, air, and energy is very small.

"But the materials we have in reserve are really pitiful compared to a war, and after the exploration of the Star of Life. The distribution of resources around the planet is unusually ordinary, and even the relatively large mineral deposits are relatively small, making it difficult to quickly and efficiently exploit a large amount of resources. ”

Because there is an unknown threat, Cao Chuan actually understands what he should do at the moment, so. Except for the mining vehicles and engineering vehicles needed by the necessary explosives, all the remaining resources were used by him to make unmanned units.

In terms of the base, more protective force fields have been installed, even if the unknown falls from the sky, their protective force field is enough to keep their base from completely turning into ruins under one blow, so they themselves in it have a chance of survival.

Unmanned units are all unmanned attack aircraft, just because the enemy they are facing is more likely to emerge from overhead, and it will no longer be a pure ground war.

Theoretically, 1 month later. The number of unmanned units here will grow to 5,000, and after 1 year, it will grow to 50,000, and Cao Chuan is not idle and leads the 3 Loli to do something else, that is, to find a way out for their resource acquisition.

"First of all, we must solve the energy problem..."Cao Chuan knows that the subsequent demand for fusion power stations is the largest, and if there is not enough electricity, how to maintain the operation of unmanned units. Not even communication, and enough energy. No matter how balanced and scarce the distribution of resources is, if you spend a little more time, the price can always be mined.

However, there is not even a planet rich in helium-3 and deuterium-tritium in the star system, let alone a gaseous planet, with a total of 6 planets. All terrestrial planets, pure lumps of rock.

He had no choice but to bring the modified Moon-Leaping spacecraft closer to the stars and use energy extraction equipment to harvest energy. In the end, it's a star, and it's Bibarnard, the giant star of the Sun. Even if it is still quite dangerous to maintain a distance of 1.5 million kilometers, but the energy on the star is so dense and high-quality, it is definitely enough to use it for a long time by filling such a ship with a moon-class spacecraft.

Taking the risk of mining a few ships of energy, so that their base can develop with peace of mind, Cao Chuan then took 3 loli to build more joint production workshops.

The joint production workshop can only manufacture the second generation of unmanned units, but cannot make itself, which is an imperfect self-replication, resulting in the joint production workshop must be manufactured by humans.

The more joint production workshops, the more unmanned units, the faster the expansion, the more capable of fighting, at least tens of millions of unmanned units, they can have a good fight with the unknown on Planet 6, under the guidance of such a theoretical thought, they have to make this choice.

"You know what... Although the parts and equipment on the Galaxy Echo are quite abundant, there is still no comparison between the Moon City and the Paradise City that produced the joint production workshop, and trying to create a joint production workshop is like using transistors to spell out an I7-level computer chip, and writing a Windows operating system by hand. ”

The manufacturing workshop is a difficult and long job, relying only on their superior physical fitness, sharp thinking speed, and much more knowledge than when they were alone on the moon 100 years ago, and countless unmanned units to assist them in simple and repetitive tasks.

In addition, the work of building more ships, expanding the size of the base, improving the industrial system, building a defensive circle, and so on cannot be stopped!

However, miracles often happen by accident.

It took Nana half a year to build 4 moon-class ships.

Cao Chuan spent half a year building three new joint production workshops by hand.

Bailian dug out 1 billion tons of earthwork, and built layers of corridors, warehouses, unmanned unit maintenance rooms, and underground factories hundreds of meters below the base.

Joan of Arc has built a large-scale protective force field tower factory, a fusion energy power station, and deployed protective force field towers for 100 unmanned guard towers around the base, so that they are not afraid of being attacked.

"This speed of development is really illogical!" Cao Chuan looked at the results of everyone's work that was evenly divided, so fruitful, if you travel back to ancient times, it is equivalent to building a modern empire by one person and beating the productivity of a huge old empire.

Here, the final reflection is on the unmanned unit, and the figure is 50,000, which is half a year ahead of his expectations.

Now, the area of the New Earth Base has expanded to 5 square kilometers, and through the digital city, he can know the movement of any part of the city anytime and anywhere, and grasp the health status of unmanned units and the tactical orders it is currently executing.

There may be war at any time, the base is purely militarized, there is a dangerous atmosphere everywhere, almost none of them are civilian facilities, and even the rooms where they live, the greenhouses where food are produced, are densely packed with beam cannons, you can imagine how tense the situation is.

"Is this the rhythm of playing Total War?" Cao Chuan laughed at himself, thinking that he might have been overly worried, the unknown expansion speed was very fast, not fast enough to spread to the hinterland of the star system in a few years.

"When it's time to be tempted, it's really hard to sleep if you don't find out the true strength of these unknowns." (To be continued.) )
