Most galaxies share the same rule, that is, the outer planets, the farther apart the two adjacent planets are.

This star system, which has no name or number, is in an unexplored universe region, and is completely unfamiliar to Qin Yan, is much larger than the solar system, so the theoretical distance between the outermost planet and the second sequence of planets in adjacent orbits is about 4 billion kilometers.

You must know that Pluto, the farthest star in the solar system, is only more than 5 billion kilometers away from the sun, which shows how big this star system is.

But!

This is the closest distance between two planets in the same orbit, and if one is at one end of the star and the other is on the other, the distance will increase tenfold or more!

Will Qin Yan have such good luck that he happened to encounter the overlapping orbits of the two planets?

This is very unlikely, so his goal is not to be on the second planet, which is too far away from the star, and if nothing else, it is also a frozen planet with no rocky layers, and it is almost impossible for such a planet to have dense mineral deposits.

His goal is to be one of the three planets that are most likely to have life in the central region of 16 planets, which has been analyzed by high-tech equipment.

According to the current orbit, these three planets are in the 9th, 10th, and 11th positions respectively, and the closest to the wormhole is the one in the 9th sequence, with a straight-line distance of about 13 billion kilometers, which is more than double the distance from the sun to Pluto.

The long-term continuous spatial transfer is, in a way, as boring as wormhole jumping.

After more than a month, Qin Yan and Hou Qing were almost numb.

Finally, the planet of the 9th sequence is close at hand, and the two of them finally end their boring and crazy journey, and the next step is to send drones into the planet to survey first.

This is a planet with a diameter of about 15,000 kilometers, which is slightly larger than the Earth.

Qin Yan and Hou Qing were suspended in space, hundreds of thousands of kilometers away from the planet, and there was nothing to see from here.

Sou!

After taking out a drone from the space box, and after a simple adjustment by Qin Yan, the drone about 100 meters long flew towards a planet more than 100,000 kilometers away at more than 1,000 times the speed of sound.

At the same time, Qin Yan opened the watch-like instrument on his wrist, this instrument has been connected to the drone, Qin Yan can use it to give orders to the drone, and the drone will continue to send all the survey data to the instrument.

As soon as the drone flew out, some of the basic data that could be surveyed from more than 100,000 kilometers away had been sent to the instrument.

Of course, these are more general data, such as the diameter of the planet, the gravitational coefficient, etc.

With the astonishing speed of the drone, the distance of more than 100,000 kilometers can be crossed in just ten minutes. The planet has an atmosphere, and the thickness of the atmosphere is greater than that of the Earth, and the main part of the Earth's atmosphere is less than 200 kilometers thick, while this planet reaches more than 300 kilometers.

The so-called main atmosphere refers to the area with the highest proportion of the planet's atmosphere, and in fact the atmosphere can extend even further.

Of course, the atmosphere that is too far away will become incredibly thin, almost as thin as it is in space.

"No oxygen?"

The speed of the drone is extremely fast, and when it is less than a thousand kilometers away from the planet, it sends data about the atmosphere, and this data makes Qin Yan breathe a sigh of relief: "Without oxygen, the atmosphere is almost composed of sulfides......

"What is sulfide?" Hou Qing asked.

"This ......"

Qin Yan felt that this was a difficult question to answer, and hesitated for a moment and said, "Anyway, it's poisonous, but it's not a threat to us, if it's an ordinary person...... Not good! ”

Rumble!

Just before he finished speaking, on the instrument connected to the drone, a holographic projection screen projected saw a pillar of fire rising into the sky. The pillar of fire cut off the drone's field of vision, and Qin Yan didn't know what was happening, and the speed of the pillar of fire was incredibly fast, and with the amazing speed of the drone, he couldn't dodge it......

No, to be precise, after the drone's intelligent dodge function is turned on, it stands to reason that it can be dodged, but the pillar of fire will change direction.

With a loud bang, the holographic projection went blank and the drone turned to ashes.

What's the situation?

Don't......

Qin Yan's mind immediately came to mind the most likely situation: that sixth-level civilization came here, and discovered that this star system contained extremely precious Parc metal, so he mobilized more people to come over, and these centaurs were divided into two groups, one group stayed next to the wormhole to prevent other competitors, and warned when necessary, and the other group was mining resources inside the planet.

This explanation is undoubtedly the most reasonable, but there is a small problem, that is, the pillar of fire - as far as Qin Yan knows, almost all high-tech weapons of advanced civilizations use energy systems, and the attacks they send out are beams, and the energy attacks of martial artists are rarely fire, most of them are sword light and sword light.

Fire can emit light, but fire and light are two different forms as an attack, and he is not so stupid that he can't tell the difference.

"Get a few more drones to try." Hou Qing proposed.

"Okay."

Anyway, drones are not as valuable as battleships, and it is nothing to lose some, and drones are to some extent intended to be used as a pathfinder.

This time it was no longer one drone, but a whole seven of them arranged in a scattered synchronized formation.

Suddenly!

Just as the drone flew to a distance of about 700 kilometers from the planet's surface, pillars of maroon fire reappeared. Whether it is the intelligent dodging of the drone itself, or Qin Yan's manual dodging through remote control, in the face of the incredibly fast and tracking ability of the pillar of fire, it has become vulnerable.

All seven drones were reimbursed, but they did not even enter the atmosphere, and through the thick atmosphere, they did not get any valuable information at all.

"It seems that it is useless to send no number of drones over." Qin Yan smiled bitterly.

"I'll try." Hou Qing frowned.

"You?"

"Living corpses."

Hearing Hou Qing say this, Qin Yan remembered that in the bloody battle more than a month ago, many enemy masters he killed were turned into living corpses by Hou Qing.

The reason for the fact that the living corpses are able to move, but since they are corpses, it means that they are no longer alive. In fact, even Hou Qing is the same, he doesn't have any active cells in his body, and according to the characteristics of the space box, he can't store living things......

That's right!

Living corpses can be placed in space chests!

Hou Qing did not immediately release the living corpse, but worked with Qin Yan to perform spatial transfer, shortening the distance of more than 100,000 kilometers to 10,000 kilometers.

It is the spiritual power that controls the living corpse, and Hou Qing's current spiritual power can only extend to 20,000 kilometers, beyond which he will not be able to control the living corpse.

Soon.

A living corpse with the initial strength of the Tianwu Quadruple Heaven was released from the space box by Hou Qing.

Under the control of Hou Qing's mental power, the living corpse also performed spatial transfer, quickly approaching the planet.

For Hou Qing, the living corpse can be used as his eyes, and everything the living corpse sees is the same as what he sees with his own eyes.

Then, to the shock of the two, it happened again!

Just when the living corpse was about 700 kilometers away from the surface of the planet, a pillar of fire rose into the sky!

This time, with the spiritual power to connect with the living corpse, Hou Qing could feel the energy of the pillar of fire with the help of the living corpse, and his face instantly condensed: "Not good!" It's not a warrior or a battleship, it's something I've never seen before...... The fire is poisonous, very terrifying poison, and the key is the power of space! ”

While talking to Qin Yan, he used his spiritual power to control the living corpse against the pillar of fire.

The attack power of the pillar of fire is not very strong, and it is equivalent to the martial artist in the early stage of the Heavenly Martial Quadruple Heaven, and he can't help the living corpse. But after the blow didn't work, the overwhelming pillar of fire appeared, densely illuminating the starry sky with a brown red, and the poor living corpse that only had the strength of the early stage of the Tianwu Quadruple Heaven didn't even have the ability to resist for a moment, and was directly burned by the pillar of fire into nothingness.

"It's not the people we met more than a month ago." Hou Qing's face was extremely solemn.

"It stands to reason that those people should be divided into two groups, one group should stay next to the wormhole to prevent other countries' fleets from coming, and the other group should develop resources on the planet...... But now it seems likely that all of their people are concentrated near the wormhole - why? ”

"Because ......"

Hearing Qin Yan's question, Hou Qing said: "They can't land, they can't even get close to this planet, they are waiting for more reinforcements, and they unfortunately ran into us." ”

"So, what is it that makes it difficult for them to get close? The only explanation is that there are other creatures living on this planet! ”

"But didn't you say there was no life on this planet?"

"Sulphur ......"

Recalling the atmospheric analysis data sent by the first drone at the beginning, Qin Yan's face turned pale: "We are all carbon-based creatures, earth humans are, Alpha Star is, and Tianqin people are also ...... All the life we have seen is carbon-based, but the universe is so big. I've seen science fiction movies before, and some people have imagined that there are silicon-based creatures, so why can't there be sulfur-based creatures? ”

"I don't understand what you're talking about."

"To put it simply, if my guess is correct, there are sulfur-based creatures on this planet, then this creature is a real alien race to us."

"What now?"

"Drones don't seem to work, and now there are three ways to go."

Qin Yan's brows furrowed, and he muttered, "First, get out of here, but in this case, you won't be able to complete the task; second, to use space transfer directly into the interior of the planet, so that it is easy to be surrounded by unknown enemy situations; Thirdly, a little closer and use the divine mind to detect, although it is not as real as the eyes, at least you can understand the situation a little more and then make further plans. ”

"Didn't you already have the answer?"

"Then the third one."

"Let's go."

The two of them no longer used spatial teleportation, but remained vigilant and slowly flew towards the planet, and their divine thoughts immediately penetrated into the thick atmosphere.
