After a few days of sailing.

The Nine Heavens Xuannu approached Mars' low-Earth orbit.

Nuwa steered the spacecraft, slowing down, descending altitude, and entering the thin Martian atmosphere.

I opened all kinds of scanning machines and scanned the landforms on the surface of Mars.

And a red dot marked on a sketch page of the alien diary is roughly around 43 degrees north latitude and 120 degrees east longitude on Mars.

The Nine Heavens Lady quickly found the location, located on a large red hill.

This hilly area is vast, covering an area of hundreds of square kilometers, and is surrounded by a heave and a slight depression in the middle, like a basin, which should be formed by the impact of meteorites outside the sky.

The agent ship that the mysterious alien is on should be in this hill or in the central crater.

Nuwa, who controlled the Nine Heavens Xuannu, carried out a detailed scan of the vicinity.

Including optical scanning, ground radar scanning, magnetic anomaly sensing scanning, and so on...... From the surface environment to structures tens of meters underground, it can be scanned clearly.

Of course, the focus is on the magnetic anomaly sensing equipment, the scanned scene, generally most of the spacecraft are made of metal structure, there are many metal equipment inside, affected by the geomagnetic field, it will be magnetic after a long time, so metal objects are easy to be scanned by magnetic anomaly sensing equipment.

With the sensitivity of the magnetic anomaly sensing equipment equipped with the "Nine Heavens Xuannu", the fist-sized metal within 100 kilometers can be clearly displayed.

However, it was repeatedly scanned three times around the coordinates.

Nuwa reported: "No trace, master, no trace of the alien mysterious spaceship." ”

"Mark the place, nothing?" Chen Jin asked.

"No, but after putting down the rover, according to the distribution of soil layers in the central area of the basin, it was inferred that there were traces of large objects sitting in the pit in the center of the basin."

Nuwa sent a computer simulation.

Based on the soil traces at the bottom of the pit, the outline of a large object was simulated.

Circular structure.

The diameter is about fifty meters.

"Flying saucers?" A word popped up in Chen Jin's head.

"It should be a saucer-shaped vehicle, this kind of space flight device has many advantages and is relatively common."

"Now that it's gone, does that mean another alien spy drove it away from Mars?" Chen Jindao.

"There's a good chance that's the case, master, but it's not 100% sure yet, unless you scan the whole of Mars."

"How long will it take to scan them all?"

"Do I need to scan them all in about three days?"

"Yes, of course! It's a little safer that way. ”

Chen Jin nodded, the mysterious flying machine at that coordinate point is gone, it doesn't mean that the aliens must have left, and they have to be completely eliminated.

"Good master."

Nuwa manipulated the Nine Heavens Xuannu to rise to an altitude of about 100km and began to scan.

Mars is only 53% the diameter of Helfa Planet, has a surface area of about 145 million square kilometers, and has only 11% of the mass of Hellfa Planet...... It is small in size and light in density, inactive in geological activity, has a thin atmosphere (only 1% of the density of the planet Helfa), and contains a small amount of water resources in the polar regions.

As for the many widely circulated rumors that "life has ever existed on Mars", they are basically all fake, all in order to deceive clicks and traffic.

If you think about it, how can life be born in an environment where there is no active volcanic activity, the density of the atmosphere is only 1%, and most of the area is devoid of water.

The so-called Martian is just an entertainment concept.

Of course, it is still good to be a colonized planet, and in the history of Helfa Planet, there has been a wave of Mars reclamation fever, and the number of Martian immigrants once exceeded one million.

But after the heat has passed, immigrating to Mars is no longer a cool thing, and many Martian immigrants have given up their lives on Mars and returned to the planet Haifa due to the harsh and boring living environment, scarce water resources, monotonous entertainment activities and high cost of living.

In addition, due to the lack of income, countries have cut spending on Mars development.

Dozens of Martian settlement bases, all of which have been abandoned.

Mars, which has been lively for a while, has returned to its former coldness.

In the process of scanning the surface of Mars, Nuwa saw many capsule houses, as well as many abandoned vehicles and equipment.

Chen Jin shook his head and said, "Nuwa, there seems to be a lot of iron ore on Mars, wouldn't it be profitable to mine a large amount of iron and transport it back to Haierfa, or some resources with higher value will be on the planet Haierfa...... Why can't Martian colonization continue? ”

"The cost is too high."

"There are statistics: the cost of mining 1 kilogram of iron ore on Mars is 1,730 times that of Haierfa mining; Even the cost of mining high-value rare earths is 260 times that of Haierfa and more than 20 times higher than that of mining on the moon...... The low cost-effectiveness ratio is the main reason why Mars is abandoned. ”

"Unless technology is further developed, when interstellar mining becomes profitable, we will enter the era of true interstellar colonization."

"But for us, we can exploit the mineral resources of the Moon, Mars, meteorite belts and other planets...... We don't have to think about cost-effectiveness, we need more resources. ”

Nuwa said.

Chen Jin nodded, indeed, for him, mining near minerals and distant minerals is the difference between consuming 1 kilowatt-hour of electricity and 10 kilowatt-hours of electricity, and mining efficiency of 1 and 10...... In fact, what is the difference, it is enough that he has mines.

Nuwa proceeds with the scan.

About two days later.

Scan to the South Pole of Mars.

As soon as she passed through a large immigration base, Nuwa immediately slowed down and suddenly turned around!

Aim all the scanning equipment at the central clearing of the immigration base, and aim at a giant butterfly-shaped device standing in the center of the clearing.

Send a message now:

"Master, Nuwa has made a major discovery!"

"Suspected discovery of an alien vehicle device."

"Suspected discovery of alien aircraft!"

Ten minutes later.

Chen Jin hurriedly returned to the Dakeng base and replied in the communicator: "Nuwa, what you said is really false?" ”

"It's a real master!"

Nuwa sent a large number of pictures and videos back and presented them in front of Chen Jin.

The butterfly-shaped device in the picture and video is also about 50 meters in diameter and about 30 meters in height, with a silver-gray appearance, quite like a hat.

"Are there any aliens in there?"

Chen Jin asked subconsciously, looking highly vigilant!

"Not sure, judging by the dust on the surface of the device, it seems that it has not moved for a long time, and for safety reasons, we can take two measures: first, destroy it immediately with weapons; Second, place weapons around it first, then check it, gather some intelligence, and detonate the weapon as soon as there is a threat! ”

The Nine Heavens Xuannu is carrying 10 nuclear weapons, with a yield of 100,000 tons, and the tens of millions of degrees of high temperature generated at the center of the explosion after the explosion can destroy all matter.

The option now in front of Chen Jin is that he does not have to check and destroy it immediately; After placing the nuclear bomb around the butterfly-shaped vehicle to ensure that it can be destroyed at any time, send a robot to approach the aircraft and collect any information.

"Second, check it out!"

Although she felt a little strange, Nuwa said that the aircraft had not moved for a long time, and many huge footprints had been found on the ground around it, and there were no lights flashing on the surface of the butterfly aircraft, and no electromagnetic signals were emitted, indicating that it might be in a state of power failure.

Destroying it directly cuts off the possibility of gathering more information.

"It's the master."

As a result, all the nuclear bombs were arranged around the butterfly-shaped aircraft and detonated remotely at any time.

Another team of robots was sent over.

About thirty minutes later.

Some of the messages sent by Nuwa made a sentence pop up in Chen Jin's mind:

Pick up an alien spaceship.
