He Shanshan continued to slip around and returned to the City Lord's Mansion.

When he walked by the lake of the mansion, he suddenly remembered the little dragon in the lake, he hadn't seen it for a long time, so he stood by the lake and called a few times.

"Little Jiaolong, come out and talk for a while!"

A moment later, the little dragon's huge head surfaced and looked at him with some surprise.

"Well, the bead of light you've been thinking about." Liu Xing took out two light beads from the jade wrench and threw them to it.

Xiao Jiaolong hesitated for a moment, but still caught the light bead, his eyes were full of heat.

"See you next time, I'm very busy now, I don't have time to talk to you." Liu Xing smiled and turned to leave, this little Jiaolong has grown a lot, and it doesn't seem very appropriate to call it a little Jiaolong.

Xiao Jiaolong looked at Liu Xing's back suspiciously, wondering in his heart, why did this miser suddenly be generous today? Sniffed and sank into the water.

……

As soon as Liu Xing stepped on the steps of the mansion gate, Hu Die was already looking forward to it.

She saw that the two of them were like glue, and she couldn't tell what it was like in her heart, but she still said with a smile:

"Hey, why did you come back?"

"Well, I went out to do something serious and set up a super seminary in the city, and let Shanshan be the dean."

Liu Xingzheng stared at Hu Die and said tentatively.

"Sister Shanshan is the dean, congratulations." Hu Die quietly pulled Shanshan over, talking and laughing. A look of sisterly affection.

Liu Xingdu saw it in his eyes, and it seemed that it was right to arrange an errand for them, so as not to be jealous if they had nothing to do all day long.

He carried the shelf and went back to his room to practice alone. I need to practice the sword formation tonight, and some of them are busy.

……

Early the next morning.

Liu Xing is ready to go, Shanshan and Hu Die can also dress up, looking more bright and moving, especially Hu Die, she has always been plain and dressed simply.

Today, I wore a pink skirt, pink gemstone pendants, and pink diamond earrings.

"Hu Die, we're not tourists, are you?" Liu Xing said unexpectedly.

"Hee-hee, just change it on the spaceship, how about it, pretty!" Hu Die spun around lightly.

"Well, good-looking is good-looking, but wait and change into combat uniforms." Liu Xing said with a soothing face.

The three of them were just about to get on the spaceship, when the fire unicorn actually fell from the sky.

"I'm going too!"

Liu Xing said in surprise: "Isn't Mars bad? ”

"Oh no, it's too cold in here, I don't like this." The fire unicorn wants its head like a rattle.

"Alright, let's go together."

Liu Xing didn't stop it, blew a whistle, summoned the black head, and then walked onto the big black spaceship.

"Go, Djinnstar!"

……

The giant spirit star is flying in the direction of the earth, this trajectory is really weird, it stands to reason, it should be caught by the gravitational pull of the sun, but the giant planet is a ball with a rubber band, and after passing shoulders with the earth, before reaching Venus, it was inexplicably flying back with an arc.

So it only takes about nine days to reach the giant planet this time.

Liu Xing's painstaking cultivation of the sword array on the spaceship, from the two flying swords at the beginning to cooperate with each other, and then to the three and four swords later, it became more and more difficult.

Three flying swords can form a three-talent array.

Four flying swords can form a four-elephant array.

Five-shank five-element array.

Six-handled hexagram;

Seven-handled Beidou Array;

Eight-handled Bagua Array;

Nine-shank nine-palace array;

……

Up to ninety-nine eighty-one flying swords, the variations are endless.

The mystery contained in this is very profound, and Liu Xing can only learn the four elephant arrays of the four flying swords first. And it is to draw a scoop according to the gourd, and it has not yet started.

These formations were originally exquisite formations that had been studied by the predecessors for dozens of generations in their lifetimes, how could they be so easy to understand.

But he is not in a hurry, originally the sword formation is the scope of Jindan monk's research, Jindan monk has a lifespan of four or five hundred years, and he can always learn some if he slowly comprehends.

He is also a swallowing date, learning a little at will, but the power of the flying sword has more than doubled. And the cooperation between the flying swords is closer, and it is more weird, which makes people unguardable.

In the past, he controlled a flying sword, and if he was swung away, there would always be free time, but now the four flying swords are perfectly coordinated, and the combat power is naturally greatly improved.

……

The spacecraft flew lonely in space, and seven days later, it flew to the vicinity of Earth.

Liu Xing walked out of the rest cabin and looked at the earth that was no longer blue with Hu Dieshanshan.

At this time, the earth is gray and very ugly.

"Shall we go back and have a look?" Shanshan asked worriedly.

"Let's go check it out, it won't take much time." Liu Xing nodded and ordered the Big Black spaceship to fly in the direction of Yuezhou City.

The spaceship passed through the thick dust and finally landed on the original site of Yuezhou City, but at this time Yuezhou City was already submerged by the sea. You can only vaguely see a few high mountains in the distance.

The earth's global volcanoes have erupted, the temperature has risen rapidly, the polar glaciers have long melted, the sea level has risen by more than 50 meters, and the submarine volcanoes are raging, the sea water is not calm, it can be said to be a violent wind and waves.

The scorching heat vaporizes the seawater, and then it is mixed with volcanic dust and meteorite powder in the middle of the air, and it falls, at this time, the rain pours down.

The sea water is even more filthy, a large number of marine life has died, and the dust is indefatigable.

"There are still tens of millions of people underground, and I don't know what happened." Liu Xing sighed.

"The violent earthquake, coupled with the fact that the outlet was flooded by seawater, is only afraid that the people below will be more than lucky." Hu Die sighed.

In the face of nature, human life is really as small as ants.

"It's still comfortable here, it's hot, and there's a smell of realgar in the air, farewell, I'm going to cultivate." Only the fire unicorn was in a happy mood and took off into the air.

The three of them stared at the sea water under their feet in a daze.

Suddenly, a spaceship burst out of the sea and flew into the sky.

"Hey, wait!"

Liu Xing Yujian flew and hurriedly caught up.

Fortunately, when the spaceship that had just rushed out found the big black spaceship, it stopped curiously and suspended in mid-air.

Liu Xing cautiously flew over, and the spaceship opened the hatch and let him in.

When several people inside saw him, they were very surprised.

"Hey, you're Liu Xing, why are you still on Earth?" An officer asked, surprised.

"Oh, come back and take a look, I didn't expect there to be survivors in Yuezhou City." Liu Xing was happy to see a living person here, not to mention how happy he was, although he didn't know these people in front of him.

"There are a lot of survivors, but many of them have moved to the plateau, which is submerged by the sea and can no longer survive." The officer's face looked pale and his eyes were tired, but his face was still full of smugness.

"What? And a lot of survivors? Liu Xing was surprised, he saw with his own eyes how miserable the situation was that day, and there were still many survivors in this dungeon.

"Well, it took tens of millions of people nearly a year to build the dungeon, and it is still very strong, at this time, there are still tens of millions of survivors in the dungeon who have not left, I see that you have a spaceship, or you can also take a group of people to send them to the plateau." The officer suggested.

"No problem, it's obligatory! How to get in? Liu Xing asked, he had always felt ashamed of the people of Yuezhou City, who had treated Liu Xing as a hero before.

"I'll take you there, can your flying sword carry people?" The officer asked curiously.

"No problem, let's go!"

Liu Xing summoned the flying sword, stepped on the tip of the sword, pulled the officer, let him step on the hilt, and flew back to the Big Black spaceship slowly.

The officer looked at the Big Black spacecraft curiously, looked at it for a few seconds, gave a thumbs up, and said:

"You're not bad! By the way, my name is Zhou Zheng, and I am a captain in the dungeon of Yuezhou. It's a pleasure to meet you guys. ”

"Hello." Shanshan and Hu Die also came over to say hello.

"Zhou Zheng, report a position. Let's go down! Liu Xing smiled casually, his mind had already flown to the dungeon.

Zhou Zheng reported the location, and the big black flew into the water and slowly dived into the target position.

This is a curved entrance, and the spacecraft cannot continue to move forward when it reaches this position, so Liu Xing and the others can only open the hatch and move forward on foot.

Yes, on foot, because there was no sea water here, it was blocked by air pressure, and the officer led them around eight times before they came to a sealed steel gate.

There were a few surveillance robots on duty at the door, the officer said a few commands, the robots put down their guns, and continued to patrol, then he walked to the gate, entered a string of passwords, bent down and swept into the iris, and the steel gate slowly opened.

Inside is another steel passage, but the air is much better, and at the end, there is a large elevator.

"Get on the elevator and go down to a depth of 300 meters, and it will be the underground city of Yuezhou City." Zhou Zheng introduced with a smile.

Liu Xing and the others couldn't help but be amazed, this dungeon was made of steel, no wonder it could withstand a strong earthquake and not collapse.

"And where does the air come from?"

Shanshan asked curiously.

"There are several vents in the dungeon, all in the mountains, so the ventilation is still no problem, and the dungeon has an air purification system." Zhou Zheng said proudly.

Really well thought out!

Take the elevator down to the bottom of three hundred meters, and in front of them is a huge underground city hall, where the lights are bright, the temperature is suitable, the air is quite fresh, the height of the cave is at least more than a hundred meters, and it is not boring to walk inside.

"I used to think that the walls of Yuezhou City were majestic, but compared to this dungeon, it was nothing at all!" Liu Xing exclaimed.

It was a hexagonal square, and no one else was wandering around at this time, except for a few security guards.

"What about people?"

"In the rest pod! The whole dungeon is designed to be a spherical shape, and the cabin space inside is not large, only a dozen square meters, hehe, it is very crowded, but there is nothing to do now. Zhou Zheng said with a wry smile.

Liu Xing nodded, it's good to survive, what kind of living environment can you talk about.

Zhou Zheng asked them to wait here, and he went to negotiate, and it didn't take long for more than a hundred young men to be brought out.

"Why are they all men?" Shanshan said unhappily.

"Now the outside environment is bad, and the elderly, children, and women can't stand it, so they can only choose some young and strong young men to go out to do construction, and then take them out when the outside environment improves in the future."

Zhou Zheng scratched his head embarrassedly and said helplessly.

When Shanshan heard this, her face softened a lot.

Hundreds of people took the elevator to the ground, they were very curious about the outside world, but after they got on the big black spaceship and flew out of the water, many people shouted in shock.

The outside world is not an exaggeration to describe it as hell, the thick flying dust blocks the sun, and there are countless dust particles floating in the air, and the real world is gray, a hundred times more serious than the worst haze weather.

Volcanic eruptions around the world, with temperatures of at least fifty or sixty degrees, and haze in the air, normal people simply cannot survive.

High temperatures, haze, acid rain......

It can be said that the earth's environment at this time is much worse than that of Mars.
