After more than 70 years, Su Meng finally came to her third destination.

Here, it is not the same as Su Meng expected.

Originally, Su Meng guessed that this place should be very desolate, after all, although life is common in the universe, not every planet has civilization.

Su Meng looked at the data displayed on the big screen, and next to Su Tian was sleeping, Su Tian's body was placed in a space ball a few centimeters large, suspended by Su Meng's side.

From the outside, it is only a few centimeters in size, but on the inside, it is a spherical space with a diameter of a thousand meters.

Su Meng's understanding of the rules of space has deepened, and now he can make a super space ball with an outer volume of one cubic centimeter and an internal volume of 3.9 billion cubic meters.

The sister next to her was placed in a space ball with a diameter of less than a few centimeters, still in time slowdown.

Su Meng's understanding of the rules of time is also deeper, and the time deceleration state that can be controlled now has reached 1:100,000 after two breakthroughs in understanding, making Su Tian's 10 hours equivalent to 110 years in the outside world.

Su Tian has been sleeping since twenty years ago, and now, the real time of Su Tian's place has only passed less than 2 hours, if Su Meng maintains her current state, Su Tian will have to wait for about 90 years to wake up.

Due to the understanding of the rules of space, Su Meng here, the total amount of material that can be stored in the body space has increased by a thousand times.

Originally, 2,500 trillion tons of matter were stored, but now they can be stored up to 25 billion trillion tons.

So that Su Meng here, even if he decomposes a few gas planets, it is difficult to fill his body in one empty space.

On the large screen in front of you, there is some data and a magnified instant image, which is synthesized by collecting data from optical telescopes by computer.

Although it is an instant image, it is still a close to static existence, and in the instant image, it is a spiral-shaped unnatural creation.

Spectral analysis has shown that the artifact has been around for more than 300 million years, and life detection systems have shown that there is no living life on the planet, but some traces of life.

Obviously, Su Meng came to a planet that once had a civilization, and whether it was a high-level civilization or a low-level civilization needed further observation to determine.

Last time in that low-level civilization, Su Meng went directly to the landing planet, but this time she didn't dare to land directly, after all, the civilization ruins below, whether it is a low-level civilization ruins or high-level civilization ruins is really hard to say, in case it is a high-level civilization, Su Meng may encounter unpredictable dangers, so everything is still cautious.

Su Meng created a new detection device, the original detection device has long been destroyed, after all, decades have passed, Su Meng's technology has also made great progress, not only to develop a more perfect ion engine, but also in the ordinary polymer materials, there have been some progress, Su Meng made the strongest polymer material, currently has 1.2 times the hardness of diamond, but the density is only one-tenth of diamond.

Su Meng quickly finished debugging the new detection device, and then took the detection device to the front of the inner side of the outer wall of the spacecraft, and with a thought, a hole was cracked in the metal outer wall several meters thick of the spacecraft, and the detector was released by Su Meng.

After the probe flew out of Su Meng's spaceship, it fell directly to the ground.

At the time of the fall to half the distance, the ion propulsion engine started, and the probe began to slow down, and when it was more than two thousand meters above the ground, the speed of the probe was reduced to zero, and then it gained the ability to move and began to continue to fly steadily downward.

Here, Su Meng was controlling the detector while looking at the real-time images from the detector on the screen.

Of course, there is more than one ruin on this planet, in fact, in the past few days, Su Meng has counted seven ruins, which seem to be seven different city ruins, and the range of these ruins is very large, and the smallest city ruins also have a range of hundreds of kilometers.

Su Meng first detected the largest ruins here, the ruins are located near the equator, the most conspicuous building in the ruins is a spiral building more than 5,000 meters high, it is like a mountain peak, and there is a natural meaning in it, it is obvious that this civilization can build such a building, at least in terms of architecture, it is much higher than humans.

When I saw this building in space before, it didn't feel too obvious, but when Su Meng controlled the probe to really approach, I found that it looked bigger than Su Meng imagined.

And when Su Meng controlled the detector and finally landed in front of this spiral building, he couldn't see all of it, and what caught his eye was a huge building complex.

Most of these buildings are dilapidated and appear to be part of some kind of weaponry.

Although it is difficult to understand, Su Meng's huge analytical power allows her to see that these buildings should have been part of some kind of weapon, and the materials used to build these buildings, as well as the damaged structures inside, indicate that this is not a residential building, but a structure similar to a computer.

Su Meng controlled the detector and began to analyze these buildings, these buildings are located on the ground below the spiral tower, there are huge connecting loops connecting these buildings to the spiral tower, although these connecting loops are hidden underground, but Su Meng's detector is equipped with X-ray scanning radar and infrasonic radar, and it is natural to see some creations below the ground.

After some analysis, Su Meng found that the technological level of this civilization should be classified as E-class, and this spiral tower was a ground-based gamma-ray weapon.

This ground-based gamma-ray weapon can emit a huge amount of energy when it is in good condition, and can destroy billion-ton spaceships.

Of course, its role is only defense, and it cannot actively attack.

These buildings use a hybrid of silicon and boron, which is very complex, and Su Meng believes that the efficiency of this hybrid circuit is not high, and the only advantage is that it is more stable and can withstand several times the overload.

Su Meng controlled the probe to fly to the spiral tower and entered the spiral tower to collect data.

Some magical gamma-ray emission and distortion devices were captured by Su Meng's detector, and a large amount of data was uploaded to Su Meng's spaceship main computer, all of which were saved, and these data were all priceless, Su Meng herself could not have imagined that these technologies were all recorded at the moment and became her things.

Su Meng then began to explore the entire ruins, and she found that the basic power supply circuit used by these people turned out to be molecular graphite wires, and the spiral tower was made of gold wires.

In the ruins, Su Meng found some corpses, not many, only less than one percent of the capacity of the entire ruins. And the reason for the death of the owners of these corpses is the same, it seems that it was an attack caused by a poisonous gas.

Hundreds of millions of years have passed, and everything here is extremely fragile, most of the exterior of the ruins has been sandified, and the inner area has barely maintained its former shape.

The dead beings looked three points similar in appearance to humans, they had dexterous limbs, two legs and two hands, and two ausles that could be used as feet or hands, and it is worth mentioning that their tails had also degenerated in evolution.

Their eyes have an outer membrane, like a fish, and their dark eyes seem to be some kind of structure that is different from the compound eyes of insects and different from the human eyeballs.

It is worth mentioning that the way this civilization obtains energy seems to be directly drilled into the earth's core, using a certain way to directly convert the thermal energy of the earth's core into electricity.

Su Meng found a power tower that went straight to the core of the earth, the pure black tower body, at the moment it was broken to only half of it, the energy from the ground, I don't know where it was damaged, and at this moment this tower can't output any power at all.

Su Meng's probe descended and released a spider mechanical beast, which was ordered to detect the Black Tower, and then began to make holes in the ground, preparing to enter the underground to investigate.

Su Meng thinks that this technology is very good, and she estimates that if she can get this technology, then she can create a more efficient device for converting heat energy into electricity, thereby increasing the output power of the super giant nuclear battery, so that the spacecraft can accelerate to 30% of the speed of light, at least half.

Su Meng's eyes were very expectant, watching the mechanical spider body burrow under the ground in the surveillance screen.
