Countless kilometers away, near a wide underground fissure.

Black smoke swirled and gears roared.

Hundreds of thousands of robot puppets are busy working, transporting wood, coal and other materials to the warehouse.

The mechanical core of these puppets also has the shadow of the technology of the Origin Fire Civilization. Naturally, the knowledge that humans originally traded in the past played a major role.

Since Green City started a new journey, the Underground Alliance has grown at an unprecedented speed, and now has basically digested the technology of human trading.

"I announce that the first trial of the Sky City of the Underground Alliance has officially begun!"

Following the order, the entire ground trembled slightly, and the city left the ground with a "bang" and slowly rose like a hot air balloon.

"Report to the Governor! The city's operating status is normal."

"Each generator set is normal!"

"Current altitude, 300 meters... 500 meters... 1,000 meters."

"I announce that the first trial flight performed perfectly. The Sky City will maintain an altitude of 3,000 meters for about a month."

As soon as this order came out, both the residents on the ground and in the city burst into loud cheers.

"We made it!"

The faces of these 12 races are filled with rich smiles.

The bright sun shines on their faces. Over the years, they have gradually become accustomed to life on the surface.

The underground alliance's small cave has moved to the surface city.

The end of this trial voyage means that the "Underground Alliance" has the ability to travel with the entire city.

Now, the only thing missing is a little determination - the determination to leave this fertile land and go to a distant place.

"I wonder if there are any new opportunities for our human friends? It's been a long time since we last contacted each other." The civilization leaders of the Underground Alliance had subtle joy on their faces.

They had never used the branches of the poppy tree left by Lu Yuan back then - it took a lot of energy to communicate with each other, so it was better to save money. Everyone knew this truth.

Ancient insects sprang out of the soil and suppressed these arrogant guys. How far have you achieved so much that you are so proud of it?

"Human civilization naturally rises in adversity. Opportunities and risks are always proportional, and continuous growth in crises is the theme of the times."

"How long do you have to stay near the rift?"

It is secretly thinking, if you knew that human beings might be destroyed if they encountered [ghosts], wouldn't they be so scared that they would huddle here for the rest of their lives?

Inappropriate, inappropriate!

But unexpectedly, as soon as it started to suppress, these high-level civilization officials had already begun to retreat.

The leader of the squinty-eyed clan twisted the body's sense of touch and said guiltily: "What Lord Gu Zhong said is... our current combat effectiveness is still inferior to humans. We will continue to develop our military here for another hundred years."

"As long as we are stronger than humans, we will definitely set off!"

Gu Zhong almost spit out a mouthful of old blood, wishing he could swallow these guys in one bite!

But it seems to make some sense.

It turned its head and sighed slightly in its heart when it saw the scene of everyone being excited.

"Although the Underground Alliance has always stayed here and refused to leave, it only has this shortcoming."

"Sometimes when I think about it, it's not that big of a deal. At least they are still working hard, while more civilizations are still spinning around... It's better to be safe!"

"As long as we can use 'luck', our underground alliance will be a serious third-level civilization."

Thinking about it this way, it gives a sense of joy of harvest.

Of course, the Underground Alliance does not have much luck.

Most of them were used for the expansion of the small cave sky, and some were corrupted by ancient insects and used to treat blight.

Coupled with the 900 points of luck that Lu Yuan traded, it only has a little over 1,000 in hand, which can only be considered a small fortune.

"If it doesn't work out, I'll just give them some luck."

"At least let them have a chance to experiment."

"Ahem... Let me ask you, do you have any ideas about the technology of third-level civilization?"

"Reporting to your lord, we do not have the background of humans, so we are unable to study spiritual speech technology like humans."

"However, large-scale glyph combinations such as harvest blessings can still be developed. There is currently little progress."

"Well done, keep it up."

It touched its ancient insect horns with its strong forelimbs...well, it had probably grown out, but it was just the same thing with no fighting power.

After all, insects also want to save face. Without this sacred horn, they cannot hold their head high in front of the Underground Alliance.

"When my ancient insect horns grow, it's not impossible to give them to you to study the technology of level three civilization..."

Thinking of this, Gu Zhong was vaguely worried about human beings. He wondered what happened to Lu Yuan and whether he was free from the crisis of [ghost]?

"Human beings are really a bunch of troublesome people...if you die in some other dimension, you won't be able to get your inheritance. It's a shame that I even sold the horns."

"I should have known that I would have left the Horns and [Immortal Palace] to the Underground Alliance..."

The mythical ancient insect as huge as a mountain felt a faint regret in his heart.

That was a valuable legacy left by the gear civilization. Could it be that I messed it up?

Although humans have deep luck, how can the underground alliance they have cultivated be pleasing to their eyes?

Look at these lizard men, tauren, and dark steel men, which one is not a good player with a hundred caps?

Why did lard suddenly become so obsessed with it that he gave away the good stuff?!

The more Gu Zhong thought about it, the more annoyed he became.

At this moment, it felt the fairy palace in its body trembled, and its heart suddenly moved: "It seems that humans are still alive. I have to beat that kid to make him be more cautious."

"If it doesn't work, let him return the fairy palace to me before he dies."

The huge figure of the ancient insect slowly appeared in the huge fairy palace.

Although it is still powerful, it is not the main body after all. The size has shrunk from the size of a mountain to the level of a large truck, and it always feels a little less imposing.

Strangely, standing across the table, in addition to Lu Yuan's huge giant, there were actually six strange creatures.

What's going on? Are there any guests already?

"Your Majesty the Ancient Insect, this is our first meeting." Crystal Man said calmly, "We are a group of aliens who stayed at the warp point of Pangu Delta."

Gu Chong was wondering, who are you?

Do I know you?

Lu Yuandao: "Your Majesty the Ancient Insect, these people are the seniors I met in that city with [ghosts]. You may have the same purpose."

Same purpose?!

Gu Chong made a look of sudden realization and became eager to give it a try: "So that's it! Lu Yuan, are you overturning your position and are you going to explain your inheritance?"

"I don't care about the other things. Life and death are destiny, and wealth is in heaven."

"If you die, I don't need any other inheritance."

"But Immortal Palace, you must return it to me. This thing is contraband and must be given to a civilization with potential. You strangers, don't get involved in this kind of thing. There is no civilization behind you."

Lu Yuan was speechless: "How can I return it to you?"

"The Immortal Palace can teleport itself! The premise is that there are no living things in it! Hurry up, you are about to die, and by the way, give me your civilization points."

You can't lie in this place, you are still thinking about it, damn, Lu Yuan is sweating profusely.

Stranger, you look at me, I look at you, and then I look at Lu Yuan. Your old friend seems not very smart.

"Ahem, isn't this still alive? We have found a way to deal with [ghosts], so you don't need to worry about it for the time being."

"Our common purpose is to respond to the epochal disaster!"

Gu Chong immediately slapped his mouth, feeling a little embarrassed.

You guys are so high-minded that you make me completely incompetent.

Suddenly, its fake "horns" were raised higher, as if this posture could restore its strength.

Crystal Man fumbled around in his arms for a long time and took out a bottle the size of eye drops: "Your Majesty the Ancient Insect, I seem to have heard of you... are you a parasite on the Demonic Myth?"

Gu Zhong snorted coldly: "What's wrong? The myth of the demon has passed away, and now only I, Gu Zhong, is alive... so what about the parasites?"

Crystal Human said: "I come from the Jingcon clan. Our ancestors may have met you a long time ago."

"I can't remember for a long time...what do you want from me?"

"This is our meeting gift for you... I hope you like it."

This crystal glass bottle is shining on the table.

Lu Yuan was a little jealous. As ancient beings, these strangers were actually very rich, but they had always searched for them. He didn't expect that they would come up with treasures this time.

The globe-like device automatically identified the treasure and transmitted the information about the treasure to the ancient insect's mind.
