The place of this impact was arranged in the Mariner Grand Canyon on Mars.

The width of Mariner's Canyon is also quite amazing, reaching more than 600 kilometers at its widest point, and the depth of the canyon has also reached an astonishing depth of 8 kilometers.

Mariner's Canyon is the "King of the Canyons of the Solar System" in terms of length, width, and depth.

It's a good place to hit it, but the only downside is that it's near the Martian equator, and if it hits, it will definitely cause violent shaking in the Northern Hemisphere.

Other cities are okay, they are all composed of spaceships, but Xianmeng City is not, and the scale of the city has almost been planned and built.

"Kim, do you have a better place to impact?" Liu Xing asked a little unwillingly.

"Yes, there is a crater on Mars called Ismenia Pate that is 80 kilometers in diameter and 1,750 meters below the surrounding plains at its deepest point."

"The diameter is just right, but the depth is not enough! Or let's go dig first! ”

Liu Xing thought to himself, there are still ten days left, and there is nothing to lose by digging.

"Then go ahead, but as far as your puppet metal rat is concerned, you won't dig deep in ten days." Jin scoffed.

"Do your best, listen to the destiny of heaven!"

Walking out of the Mars Alliance Center, Liu Xing and the other two captains waved goodbye, piloted the spaceship, and flew the Pate Pot.

In fact, there are many craters on Mars, most of which are formed by meteorite impacts, and a small part are caused by volcanic eruptions.

Half an hour later, Liu Xing arrived at the Pate Pit, which was extremely desolate, and a huge pit appeared in front of him.

He leaned down and saw that the bottom of the pit was more than 1,000 meters deep, and some people's feet were weak.

Liu Xing finally understood the meaning of Xiao Jin's words, relying on his hundreds of puppet metal rats, ten days, it didn't work at all.

"Hey, forget it, so as not to waste your strength and waste spirit stones."

Liu Xing shook his head and smiled bitterly, the 80-kilometer-long pothole, really standing there alone, looked very small, and he didn't have heavy weapons, it was impossible to dig such a big hole.

"You don't die if you don't have the heart of the Yellow River, and I have already told you that it is impossible. However, this Pat pit has a strong energy radiation, and there should be a lot of energy stones underground, so you can go down and dig it. ”

"Really?"

Liu Xing was overjoyed, energy stones are good things, and they are rarer than spirit stones. If you want to travel the galaxy, you must have energy stones.

Now he has only five or six hundred energy stones, and he has consumed nearly a hundred energy stones, after all, he has flown to Mars several times, and he has also flown to the Giant Spirit Star, all of which are long-distance voyages, if all of them are consumed by spirit stones, it is estimated that thousands of spirit stones will be consumed.

He flew down the pit, unleashed hundreds of puppet metal rats, activated them, took out an energy stone and showed it to them, and ordered them to mine it. He stood with his hands in his hands, quietly watching and waiting for the result.

The bottom of the pit is also vast, at least forty kilometers in diameter, and the place where he mines is the place with the strongest energy signal, and now, he can only watch the metal rats mine.

As the day passed, the metal rats worked tirelessly and dug a deep pit with a depth of 200 meters and a diameter of more than 30 meters at the designated location, but still found nothing.

Liu Xing couldn't help but be impatient and asked:

"Xiaojin, you are unreliable, you have been digging all day."

"What are you in a hurry, you have nothing to do to cultivate, I'll just keep an eye on it."

"Well, you can stare at it, it's sleepy to watch."

Liu Xingfei got on the spaceship, he planned to refine all the remaining flying swords, and now his soul is powerful, and he can completely control more than a dozen flying swords at the same time, without any pressure.

Then learn a simpler sword formation, and the combat power will definitely skyrocket.

He chose a lounge at random, put out a bunch of spirit stones, and then cautiously took out the remaining ten flying swords, these flying swords were still given to him by the blue-robed Taoist priest of Shangqing Sect, he didn't even know the name of that person now, and he was ashamed to say it.

Some of these ten were made by the black princess, and they were extremely strong, but they lacked spirituality, and they were just the right time to be sacrificed.

Ten flying swords were placed around, and he divided the ten divine senses, leaving his own spiritual imprint in the flying swords, so that the flying swords and him had spiritual resonance, reaching the realm of human and sword unity.

It took a whole night to finish refining the ten flying swords, and now the flying swords are happily revolving around Liu Xing, and they have established a preliminary relationship with him.

Originally, I wanted to continue to practice a sword formation, after all, just using the divine sense to control the attack of the flying sword, the power is still greatly reduced, the sword formation pays attention to coordination, and the formation can make the flying sword combined, and the power is greatly increased.

However, Xiao Jin ran to his door with a shout:

"Liu Xing, energy stones, a lot of energy stones!"

Liu Xing has always felt that Xiao Jin is very cold, and his feelings fluctuate very little, even he is so excited, presumably there must be a large number of energy stones.

This wave is definitely not a loss!

He hurriedly opened the hatch and walked out of the spaceship with Xiao Jin.

On the ground was a hill of energy stones, estimated to be thousands, and they were not small, cut into a square shape by a puppet metal rat.

"Tsk, there are thousands of energy stones in just one night, I can't even dream of it!"

Liu Xing excitedly put the energy stone into the jade wrench, which was a big fortune.

At present, energy stone has not been widely developed and utilized, and other forces do not understand the importance of energy stone. They are also using radioactive ores such as uranium as an energy source.

I heard Xiaojin say that radioactive ore is good, but it is also very harmful, or energy stone is stable, clean and high-energy after all.

"It's not one night, it's two hours and twenty-eight minutes!" Xiao Jin said precisely.

"What!"

Liu Xing leaned down and saw that the puppet metal rat was busy cutting a huge energy stone, which was not good-looking, dark brown, similar to other stones, except that it was heavier.

But when you cut it inside, it's a different scene.

The inside of the energy stone is red, and from time to time it flashes with orange dots of light, like a red-hot stone. But the temperature is not high, only twenty or thirty degrees Celsius.

"This meteorite seems to be mainly composed of energy stones, and the total mass is probably more than 1,000 tons." After Xiao Jin scanned it, he estimated and said.

"Thousand tons!"

Liu Xing has no concept anymore, and a piece of energy stone is generally about ten kilograms. That's 100,000 energy stones!

"Xiao Jin, how long will these 100,000 energy stones be enough for the Big Black to fly?"

Liu Xing said stunned.

"It's enough to fly to other planetary systems, and the closest planetary system to the solar system is currently three stars in the constellation Centauri, with Proxima Centauri being only 4.22 light-years away. ”

", isn't that the three-body civilization? Xiaojin, where is there really a three-body person? ”

Liu Xing had seen aliens, but he wasn't sure if there were aliens at such a close distance.

"Yes! Technology is much more advanced than yours! ”

"Sure enough! Do they have a three-body problem? ”

Due to the chaotic three-star movement, the planet where the three-body civilization is located is sometimes captured by this star, and sometimes it is far away from the star and captured by another, which is comparable to Pluto when it is cold, and hotter than Venus when it is hot, so they must escape from this hellish world!

"Well, it's true that the Centauri three stars are chaotic after all, but their technology is tens of thousands of years ahead of yours, and they can already travel between planets. And this kind of chaos is once in a thousand years, and it is not frequent. Jin explained.

"That's not a great place to be! Not to mention that, it's too far away. Or collect energy stones after all reality. ”

Liu Xing shook off his worries and watched the puppet metal rat dig energy stones.

……

After looking at it for more than an hour, he got on the spaceship bored, and let Xiao Jin continue to stare here, looking at the speed of this excavation, I am afraid that it will not be collected in seven or eight days.

He just used this time to practice sword formation and gravity training. The former can enhance combat effectiveness, and the latter can enhance vitality.

Both offense and defense are important.

There is no hurry to learn the sword formation, the flying sword still needs to be conceived with spiritual energy, he put the flying sword in a pile of spirit stones, sat down by himself, called out the aura of the dantian, and sacrificed the flying sword.

The flying sword, a spiritual weapon, is spiritual, although the material has solidified its growth, but there is still room for operation.

The spirit weapon with the machine spirit is more than a star and a half more powerful than the spirit weapon without the machine spirit.

Of course, the machine spirit can't be cultivated in a short time, but to make the flying sword more spiritual, it can be done in a few days.

What's more, his conditions are so unique.

The aura in the dantian can allow him to release it for several days and nights without being silent, and there are a large number of top-grade spirit stones around.

As long as there is enough time, it is estimated that it will not take ten years for these flying swords to produce machine spirits, but Liu Xing is not so stupid to keep refining flying swords.

He still likes soul attacks. It's quick and easy, without a hint of pyrotechnics.

I planned the time, exercising in the gravity cabin during the day and raising flying swords at night.

Time passed, and there were more and more energy stones.

He is also adapted to 300 times gravity, and can easily punch, jump, and run in 300 times gravity. If this were placed on Mars, he would be able to leap thousands of meters at this time.

"Hehe, there's no need for Edgeworth to fly in the future!" Liu Xing smiled proudly.

At this time, he was surrounded by ten flying swords, which were full of aura and extremely spiritual, and could act autonomously according to his mind.

But there is still some distance from the automatic guardian.

In just eight days, the harvest is huge.

The energy stones alone collected 100,000 pieces, adapted to 300 times the gravity, and refined the flying sword.

Wealth, combat power, and defense are three harvests.

Grand slam!

……

"Let's go, Kim, go see how Gudelev and their side are doing!"

Liu Xing put away the puppet beast, looking at the pit called Pate with a trace of regret, eight days have passed, only a few hundred meters deep, the depth is less than 2,000 meters, far from the requirements of ten kilometers.

But it can also be used as a preparatory location, after all, this location is better than Mariner's Canyon.

There are only a few days left in the mission, and the time is pressing! Let's hope the other two captains go well.

PS: I recommend a novel by my friend "The Legend of Evil", which is very good, and I am chasing and reading it.
