When all the orbits overlap, the closest to Planet 09 is definitely Planet 08 and Planet 10, but the planets orbit the star all the time, and the orbits of all the planets in the star system overlap at the same time, which is almost impossible, at least now the closest to Planet 09 is Planet 13, which has the closest orbit to overlap.

It took nearly half a month for Qin Yan and Hou Qing to arrive at Planet 13, and the drone sent this time was not in distress, and the two entered the planet's surface safely.

This is a planet with a diameter of less than 10,000 kilometers and a circle smaller than the Earth.

Due to the proximity to the stars, the surface temperature of the planet is as high as more than 200 degrees during the day, and there is no atmosphere, which alone almost cuts off the possibility of any life.

Amazingly, Parker metal was found on this planet!

Apparently.

The fleet that was destroyed by Qin Yan and them at the beginning did not come here for a long time, and it is likely that their original target was Planet 09, but they suffered serious setbacks there, and perhaps before they had time to explore other planets, they were attacked by Formation 51 and wiped out.

Qin Yan immediately took out the equipment for mining deposits from the space box and set it up to mine the deposits on Planet 13.

At the same time, send the message back to the flagship, and have them send a few people to come and collect metal with space boxes.

Obviously, the speed of the battleship's flight is inferior to that of space transfer, and the fastest way is to let the early stage master of the Tianwu Fivefold Heaven bring the space box over: the Tianwu Fivefold Heavenly Cultivation is not as good as Qin Yan and Hou Qing, and it does not have the power of the stars to recover its spiritual power faster, so compared to the forward speed of Qin Yan and Hou Qing's partner, it is at least twenty times slower, but it is still much faster than the flight speed of the battleship.

It would take about a month and a half for Qin Yan and Hou Qing to come to Planet 13 from the wormhole, so it would take more than two years to send the members of the Tianwu Five Heavens over.

Since Qin Yan has already set up a one-stop intelligent equipment for mining and refining on Planet 13, and equipped with enough energy, even if he leaves, the equipment will automatically look for ore deposits and continue to work non-stop: it is conceivable that when the team member came over more than two years later, the mineral deposits were almost mined, and he could directly put the refined Parc metal into the space box and leave.

Undoubtedly, this is the most time-saving option.

When the flagship sent a team member to Planet 13, Qin Yan and Hou Qing flew towards another planet.

Planets orbit their stars all the time, and each planet orbits at a different speed and changes its distance from each other over time.

But one thing that won't change is that the planets closest to the star are relatively close to each other.

Planet 15.

Planet 14.

Planet 13.

Qin Yan and Hou Qing's survey has been continuing, because during this time, the survey is a few planets in the inner circle of the star system, the relative distance is not very far, so it took not too long, it only took less than three months to complete the exploration of the six planets in the inner circle.

There are a total of 16 planets in this star system, including three planets 09, 10 and 11, which are the only planets where life is possible.

The six planets in the inner circle are planets 11 to 16, including planet 11, which has been analyzed and may have signs of life.

But it turns out that there is no life on Planet 11.

In addition, not all of these six planets have Parker metal mines: although the existence of this precious metal can be found in almost every one, only two planets, 13 and 15, have formed valuable deposits for development, and most of the Parke metals on the other four planets exist in a free state, and the number is extremely rare.

This time, Qin Yan targeted Planet 10.

It is also the only one of the three planets in this galaxy that is most likely to have life that has not been explored up close.

In addition, it is worth noting that in terms of the orbits of these three planets alone, the orbit of Planet 10 is the most likely to have life: Planet 09 is a little farther away from the star and the temperature will be colder, and Planet 11 is closer to the star, and even with an Earth-like atmosphere, the temperature at the equator will exceed 60 degrees.

Of course, the planet with the most likely life is also more dangerous.

The universe is so big that there are no surprises.

On habitable planets that have not developed high technology, fleets from higher civilizations are often wiped out.

It is said that some planets with abundant aura can even breed monsters with monstrous strength, and they can destroy the world with a single move!

Qin Yan and Hou Qing were suspended in the void hundreds of thousands of kilometers away from Planet 10, and as a drone flew quickly towards the planet, the two of them were extremely nervous.

Drip! Drip! Drip!

As the drone gets closer, more and more data comes in.

The diameter of the planet is 31,820 km......

The revolution period is 539 days......

The rotation cycle is 60 hours......

Of course, these are not the most important things, the news that really surprised Qin Yan came after the drone gradually came into contact with the atmosphere.

The main components of the atmosphere are nitrogen, argon, and oxygen, of which the proportion of oxygen is as high as 40%, which is almost double the oxygen content of the earth!

There are no toxic gases except for the three main gases, which together account for more than 93% of the atmosphere.

On top of that, the atmosphere contains about 5% water vapor!

There's an atmosphere, there's oxygen, there's water......

"The drone was not attacked!" Seeing that the drone entered the atmosphere unharmed, the only worry on Qin Yan's face was swept away.

What follows is not just the data, but also the extremely vivid real picture.

Mountains and rivers.

Tree-savannah.

Flowers go wild.

The drone not only shoots from top to bottom, but also shoots 360 in different directions without dead ends, and you can see the sky bluer than the earth on the upper screen.

It's just that there are no birds in the air, and there are no giant beasts on the ground, and the drone quickly found life outside plants with the help of advanced equipment.

Although Qin Yan had never seen them, it was certain that these creatures were living organisms on habitable planets that had just entered the evolutionary stage for tens of millions of years - tens of millions of years, and for the process of gradual evolution from single-celled organisms, only these extremely inferior organisms could evolve.

This is a planet equivalent to 500 million years ago, in the Cambrian period!

It's just that the plants on this planet are extremely huge, and those lower animals such as trilobites in the Cambrian period of the earth can reach tens of meters in length, which is simply impossible on the earth, even if the earth's aura at that time is very abundant.

"Reiki Index...... More than 20,000! ”

When they saw this data, Qin Yan and Hou Qing almost didn't go completely crazy: no wonder the size of those plants and lower animals on this planet in the lower life stage would reach such a large level, all of which stemmed from the almost perverted purity and concentration of the aura on this planet.

The advantage of high technology is that many ethereal things can be objectively described with data, which also creates a hierarchy for habitable planets.

Habitable planets and having Reiki are two different concepts, a planet with Reiki is definitely habitable, but a habitable planet does not necessarily have Reiki.

In fact, more than 90% of habitable planets are aura-devoid of aura, and such planets are classified as the lowest class 1 planets among habitable planets.

After being extracted by Pangu, the reshaped earth has an aura index of only 10 points at most, and the index below 100 points is classified as a second-class planet. The aura index of 100 to 500 points is a third-class planet, then 500 to 1000 points, 1000 points to 5000 points, 5000 points to 10,000 points, 10,000 points to 50,000 points......

The habitable planets are divided into ten levels in total, and the planet in front of him is in the seventh rank, and the one where the God Domain is located, the planet with rich aura created by Pangu himself, is only comparable to the fifth class.

It can be said that the number of seventh-magnitude planets is absolutely one in ten thousand!

Is the Lyra Empire big?

Of course!

The Lyra Empire has the territory of a galaxy with 70 billion stars and more than 5 billion habitable planets.

However, the number of planets that have reached the seventh rank in the entire Lyra Empire definitely does not exceed three thousand!

Of the more than 5 billion habitable planets, less than 400 million have aura, and the higher the aura index, the lower the proportion of planets.

unimaginable......

What is the extent of the leyline spiritual source contained in a seventh-rank planet with a diameter nearly three times that of the earth: the planet where the divine domain is located has an aura index of more than 1,000 points at most, and the earthly vein spiritual source it contains is enough to make an ordinary person become a master of the late stage of the Tianwu Fifth Heaven.

It is certain that the earth vein source spirit contained in this planet is at least twenty times more than that of the planet where the divine domain is located, and this is only at least the difference in quantity, and there is also a gap in the purity of the earth vein source spirit - just like the Tianwu Sixfold Heavenly Martial Artist to the Tianwu Fourfold Heaven, not only the number of true elements has increased significantly, but the purity of the true yuan of the same unit will also be dozens of times different.

Converted in this way, this planet is enough for hundreds of ordinary people to be directly promoted to the late stage of the Heavenly Martial Five Heavens, how could it not surprise Qin Yan?

"Let's go!"

Qin Yan and Hou Qing's figures flashed one after another, and they soon appeared on this planet.

Hardly there was any pause, Qin Yan took out a device from the space, which was extremely large, and after entering a series of programs into the device, the device suddenly decomposed into hundreds of individuals, except for the main body that remained in place, those individuals that were like metal pillars flew in all directions.

As if you look at it from a distance, you will find that more than 200 individual individuals are soon evenly distributed in different parts of the planet.

As the main equipment issued a command, more than 200 individuals quickly drilled into the ground, automatically adsorbing the metals in the soil, forming a dense pipeline extending towards the main body.

That's right, this is the equipment for extracting leyline source spirits.

According to the size of the planet, a different number of individuals will be dispersed, and these individuals will extract the leyline source spirits in an area and transmit them to the main body for storage through the transportation pipeline that has been built, and the next thing Qin Yan and Hou Qing have to do is wait.

With the size of this planet, it would take at least two months to extract the leyline source spirits.

Of course, after two months, the planet will completely wither, and all life will gradually disappear, and eventually become a lifeless planet.
