Xiao Yu began intensive pre-construction preparations.

First of all, in order to build a new titanium and zirconium processing and smelting base next to a methane lake that was determined to be free of black worms, Xiao Yu spent two months next to a methane lake that was determined to be free of black worms.

Then, Xiao Yu built thousands of small nuclear fusion engines with a certain intelligence, all loaded into the Hope, and after all the preparations were made, the Hope took off smoothly and rushed to the original Earth orbit, and the construction of the Dawn began.

All kinds of bases, gathering and smelting equipment have been built, and now there is no need to expand the scale again for the time being, just maintain the current production rate, so Xiao Yu has put all the remaining energy at this stage on the construction of the Dawn in addition to dividing a fixed part of the calculation rate to maintain the operation of all bases.

In the main base, hundreds of planes take off and land back and forth every day, sending a steady stream of material resources here. Immediately after the plane landed, there will be robots to classify the raw materials they brought, send them to different processing workshops, purify, or quench again, and then be manufactured into parts, and then there are robots to transport them to the assembly workshop, assemble them into large parts, and then transport them to a large plant to assemble them.

Countless robots are like industrious worker ants, and the huge Dawn is like an ant nest. Under the busyness of these industrious ants, the Dawn gradually showed its clues.

By this time, Hope had already reached its original Earth orbit after a long two-month journey.

After years of development, an asteroid belt around the sun has been formed in the original Earth's orbit, with a total circumference of more than 1 billion kilometers and a width of about 10,000 kilometers, but the thickness is only about 10 kilometers. Xiao Yu knew that this was formed under the action of the sun's gravity. The current earth is the "ring" of the sun, just like the rings of Saturn and Jupiter. In the future, these things can no longer be called the earth, but should be called "solar rings".

After observing the operation of the current earth through the Hope, Xiao Yu sighed secretly.

He knew that under the gravitational disturbance of the outer planets, such as Jupiter and Mars, and the inner planet Venus, there would be no new planets in the Earth's orbit. Earth is a thing of the past.

It is 1.3 billion kilometers away from Xiao Yu. There is a delay of about 80 minutes between here and Titan. Therefore, Xiao Yu handed over most of the operation authority of the Hope to the pre-programmed haode program, and he only monitored the situation of the Hope at any time.

The endless stream of data was transmitted to the high-power communication satellite placed in advance at the Sun-Jupiter Galrange point, which in turn transmitted the signal to the satellite placed at the Sun-Saturn Lagrange point, and then transmitted the signal to the orbiting satellite around Saturn, and then they transmitted the signal to the orbiting satellite of Titan, so that after twists and turns, the signal could reach Xiao Yu's mind. If Xiao Yu wants to send instructions, he must also follow this process, but the order is reversed.

Through this data, Xiao Yu can know the movements of the Hope.

Hope has been surveying the underside of this "ring" in the original Earth's orbit. It is equipped with an extremely sensitive titanium zirconium detection instrument. As long as a meteorite rich in titanium and zirconium is found, and its size is within an acceptable range, Hope will take action against it.

"Huh? Hope has discovered an eligible meteorite? Xiao Yu was overjoyed in his heart, and immediately waited for the next signal to be transmitted.

This meteorite, the shape is close to a cube, the length, width and height are about ten meters, the volume is about 1,000 cubic meters, mainly composed of 30 percent rock and 69 percent ilmenite, the rest is some impurities, its mass is about 5,000 tons, heavier than the entire Hope.

According to estimates, Xiao Yu can smelt nearly 1,000 tons of titanium from this meteorite.

"It's already worth starting." Xiao Yu thought to himself, "According to the preset procedure, the next step should be to drag the Hope underneath the solar ring to get a quiet processing environment. ”

When Xiao Yu received this signal, this signal had been running in space for more than an hour, that is, it had happened more than an hour ago.

Faintly, Xiao Yu was a little nervous in his heart.

Practice is the best way to test the accuracy of a program. Although Xiao Yu had tested the program hundreds of thousands of times before the launch of the Hope, the test was only a test after all, and whether the program was running correctly or not still depended on how well it performed in practice.

The continuous signals continued to come, and Xiao Yu saw that the Hope first cautiously approached the meteorite, until the distance was shortened to thirty meters, and then launched a mechanical claw, and after firmly fixing it, the engine started, dragging the meteorite far away from the solar ring.

Everything was as Xiao Yu expected.

Seeing that his preset program had withstood the test of practice, Xiao Yu breathed a sigh of relief and continued to pay attention to the next move of the Hope.

Hope slowly brought the meteorite closer, and the 3D scanner scanned it, measured the center of gravity, density and other information, and found the best place to install the engine.

That's right, the thousands of small nuclear fusion engines that Xiao Yu built before will play a role.

Xiao Yu's Jihua is that after finding a meteorite that meets the requirements, he will install an engine on it, and let it fly to Titan by itself under the power provided by the nuclear fusion engine. After all, due to the limitation of tonnage, the transportation capacity of the Hope is really limited, and if the Hope is transported back and forth alone, I am afraid that after a hundred years, Xiao Yu will not be able to obtain enough materials.

The power that a small fusion engine can provide is extremely limited, and conversely, the acceleration it can provide to a meteorite is also limited. This means that it takes about a year for a meteorite to reach Titan, thanks to the increase in speed caused by the gravitational acceleration of stars such as Saturn and Jupiter.

But even so, this method is much more cost-effective than having the Hope be transported from one trip to another. After all, at the speed of the Hope, it would take four months to make a round trip, and even if the towed transportation method was adopted, a trip could only transport a maximum of 100,000 tons of meteorites, and there could be no more. This kind of efficiency is really low.

After closing the meteorite close enough distance, Hope opened the hatch, and several robots mounted a small fusion engine on the meteorite, and after fixing it, returned to Hope and began to search for a valuable meteorite for the next moment.

About 30 minutes after Hope left, the small fusion engine installed on the side facing the sun suddenly erupted a pale blue flame, pushing the meteorite forward to accelerate.

During the year-long flight, high-powered communications satellites scattered in space will serve as the navigation mission, ensuring that it can reach Titan safely and accurately.

Seeing that everything was going well, Xiao Yu breathed a sigh of relief in his heart and was full of confidence in this mining jihua.

Three days later, Hope found another eligible meteorite. The mass of this meteorite is much larger than that of the previous meteorite, its volume is about 30,000 cubic meters, and its mass has reached an astonishing 100,000 tons. However, its ilmenite content also reaches a staggering 80 percent.

According to estimates, in this meteorite, Xiao Yu can obtain more than 30,000 tons of titanium ore.

In Xiao Yu's setting, Hope does not have the decision-making power to decide whether to collect such a large meteorite. After sending the information to Xiao Yu, it began to track the meteorite, waiting for Xiao Yu's response.

Xiao Yu thought about it for a while, but decided to collect it. After all, more than 30,000 tons of titanium ore is not a small amount. It's just that the transport jihua still needs to be modified.

Xiao Yu quickly made an improved transport jihua and sent it to Hope.

After receiving the signal, Hope first dragged it away from the ecliptic plane according to the program's instructions, and then installed a full fifteen fusion engines on it before leaving here to continue exploring the next meteorite.

In half a year, Hope collected nearly 300 meteorites, ranging in size and mass, with the largest reaching a mass of 300,000 tons and the smallest weighing 2,000 tons. Xiao Yu has estimated that these nearly 300 meteorites are enough to provide him with about 3 million tons of titanium ore and about 1 million tons of zirconium ore, which is enough to support him to complete the first phase of Starfleet construction.

After completing all this, installing the fusion engines on the three hundred meteorites one by one, and sending them on the road, Xiao Yu gave the order to the Hope to return home.

Hope is several times faster than the meteorites, but even then, it is expected that it will take another two months for Hope to return to Titan, and then, in about four months, the first meteorite will reach Saturn's orbit. At that time, the Hope will need to pick it up, after all, there are too many variables in a year's time, and it is difficult to ensure that the meteorites can accurately hit the target.

Moreover, when entering the atmosphere, Xiao Yu did not want to lose mass due to friction with the atmosphere. That would be too much to lose. However, Xiao Yu had already done everything possible to ensure that these meteorites arrived safely at the processing plant he had prepared for them with minimal loss.

Half a year has passed, the construction of Aurora has entered the final stage, and all post-processing is currently underway, and soon, Aurora can also leave Titan and soar freely in space.

Everything is moving forward according to Xiao Yu's jihua.
