Under the illumination of the Shining Crystal, a large area of the ocean is illuminated, and even the scales on the small fish can be seen clearly. Pen & Fun & Pavilion www.biquge.info

"This fish looks delicious, ah, this one is good, oh my! Judging by the way it swims, this fish is even more delicious! ”

In short, along the way down, Lin Wanbai was all about the taste of various fish, and kept discussing the various methods of each fish.

As the depth dropped, the natural light soon disappeared, and some luminous species began to appear in the sea, and Li Yu, who was holding the Shining Crystal, attracted a group of deep-sea fish.

The largest of them is one of the largest fish, with a body length of 170 meters, and according to Lin Wanbai's estimates, this fish, after drying, can be eaten in the laboratory for two years, and there is still a surplus.

"Wanbai, I don't know if that fish is delicious or not, but what I do know is that if that fish is placed on the earth, it can poison the people of a village."

"The arsenic content in its body can make tens of thousands of people happily commit suicide and repay the balance!"

Fang Qianmo saw Lin Wanbai nostalgically watching the one hundred and seventy-meter-long fish go away, and couldn't help but say to her with a headache.

"Arsenic? It should be arsenic! It doesn't matter, I don't care about this poison at all, besides, I believe that it is precisely because of this that it tastes even more delicious! ”

Fang Qianmo's words not only did not make Lin Wanbai give up the little thought in his heart, but on that thought, it was like pouring a large barrel of oil on that thought.

After Lin Wanbai quietly gave an order to a robot, the fish was sent alive to the ecological zone of the Galaxy ten minutes later.

By the time Li Yu and the others descended to the bottom of the sea at a distance of 10,000 meters, Lin Wanbai had already transported thousands of different kinds of fish to his Milky Way.

Fang Qianmo was already numb to Lin Wanbai's behavior and didn't want to comment on it.

Fortunately, after more than 10,000 meters, the creatures in the sea have been greatly reduced, and Lin Wanbai ended her crazy hunting trip.

Continuing to descend for five thousand meters, Li Yu and the others reached their destination, an undersea plain.

The most striking thing about this submarine plain is the thing in its center.

A hundred-meter-long pillar of silver-white metal, protruding from the sand of the submarine plain, pierced the sea water and stood silently in the pitch-black water.

"A metal column? It's clearly artificial, but what's the point of a pillar being placed here? You don't need lightning protection on the bottom of the sea, right? Fang Qianmo stepped forward, came to the pillar, and knocked down the pillar gently, her first reaction when she saw this metal pillar was a lightning rod.

Lin Wanbai also jumped to the pillar, she first stroked the pillar, then rolled her eyes and kicked the pillar hard.

To tell the truth, Lin Wanbai's kick used a lot of force, when she stepped out, Zhou's sea water was discharged, and there were even torrents in the water.

And the metal pillar was also kicked and shook violently, but it did not fall as Lin Wanbai thought.

"Tsk! It's pretty good to fix! ”

I don't know if Lin Wanbai is lamenting the strength of the pillar, or showing off the strength of her strength.

Li Yu looked at the metal pillar thoughtfully, "Xiao Wei, how big is this plain?" ”

"Three hundred square kilometers."

Xiao Wei quickly gave detailed data.

"Three hundred square kilometers? It's not small! ”

Lin Wanbai approached Li Yu: "What's not small?" I heard Xiao Wei say 300 square kilometers. ”

Li Yu smiled and said to Lin Wanbai: "Do you think this undersea plain is big?" ”

"It's not small, what's wrong, this metal pillar has something to do with the plains?"

"Hehe, I won't say, you use mana to detect what's under the plain, remember, follow the metal pillar to probe down."

As soon as Li Yu said this, Fang Qianmo and the others understood that there was definitely a secret hidden under this plain, and Li Yu had already discovered it.

It's really strange, when they came down, everyone didn't use mana detection, how did Li Yu find out that there was a secret under the plain?

Regarding other people's questions, Li Yu smiled and said nothing.

"Damn! There's a city down here! Lin Wanbai quickly shouted in surprise.

As others also used their mana to probe, the secrets under this plain were also exposed to everyone

This plain under the sea, separated by a layer of sand dozens of meters thick, actually has a city buried underneath. And the metal pillars that expose the plains should be lightning rods on the top of the tallest buildings in the city!

A city, a city buried under the sea of 15,000 kilometers, a city with an area of almost 300 square kilometers.

This is something that Lin Wanbai did not expect.

After determining that there is a city below, everyone first thinks it is incredible, and then they start to discuss how to enter the city and uncover the secrets of the city.

To investigate the city buried below, Li Yu's first thing to do is how to dig the city out of the cover of sand, mud, and rocks.

At this time, Xiao Wei went out, she controlled the detection instruments in the laboratory and accurately detected the target.

After detailed mapping, Yui drew an accurate hologram of the city.

In Xiao Wei's projection, a beautiful city blooming like petals, with six petals, arching the beautiful city in the center of the city with a circular center, appeared in front of everyone's eyes.

The main body of the city, the high-rise buildings are all made of metal materials, and almost all metal buildings have metal pillars on them, and the metal pillars that were previously considered lightning protection pillars are more likely to be energy attack weapons after detailed detection.

"It's a metal city, it's hard to imagine, who would have nothing to do and build a city made entirely of metal?"

"Not to mention the amount of resources consumed, at least this design is extremely unreasonable."

Fang Qianmo frowned, looking at the city hologram projected by Xiao Wei, very puzzled. The annual production of steel on the entire planet is not known to be able to support the resources needed to build the city.

Of course, in the interstellar era, this consumption is nothing, but this kind of behavior is really incomprehensible.

"The resources that this city consumes do not come from the planet beneath our feet. I asked Xiao Yui to map the resource distribution of the entire planet, and I didn't find any abnormal, large-scale mining. ”

When Li Yu discovered this city, he thought of Fang Qianmo's question, and asked Xiao Wei to find out if the resources on this planet had been exploited in large quantities.

"That is, the city was built by aliens."

The aliens that Fang Qianmo said refer to are the aliens relative to this planet, and the laboratory is also an alien. Well, that's nonsense.

Even if it was built by aliens, but they built the city, they would adopt the principle of proximity, right? It's impossible to leave the resources that are close in front of you and not exploit them, but go to a planet a few light-years away to mine them, right?

After Maggie asked her question, Fang Qianmo didn't understand, could it be that the aliens were trying to protect the living planet, so they didn't exploit the resources on this planet.

"Hehe, you guys think too much, this city shouldn't have been built on this planet."

Li Yu found the answer.

"You mean, this city was built on another planet and then transferred to this planet?"

"That's right!"

"Hehe, it's really an alien from the Gu family!"

For this kind of alien who goes out and has to bring home with him, it's rare!

"If you probe more closely, there is a more important reason."

The increased mana detection intensity, and let Xiao Wei also increase the scanning intensity, the reason Li Yu said was finally discovered by Fang Qianmo and the others.

"Hehe, this is not only a city, but also a spaceship, Xiao Wei, I can finally find an existence with the same taste as you."

Fang Qianmo didn't expect that this city was actually a spaceship.

"That way, we don't need to clean up the stuff on it, we just go inside the city, start the ship, and let it take off!"

Sun Yixuan felt that by making this spaceship city move, it could solve a lot of problems.

"This requires us to go inside the city and check if this city ship can still operate properly!" Fang Qianmo felt that Sun Yixuan's idea was good.

"Li Yu, can you find the city's energy center?"

Obviously, the city's energy sources have been shut down or have failed, or they would not have sunk to the bottom of the sea, buried in the sediment.

Of course, it is also possible that someone deliberately let the city sink to the bottom of the sea, but because of the time and the excessive energy consumption, the city went into hibernation.

Whatever the reason, what Li Yu and they have to do now is to restore the city's energy supply.

"Here, there is still some weak energy response in this place, and I believe it should be the most important place in the city, and it may be the energy center."

"Then we'll go to this place."

A place of suspected energy center, located in the center of the city, at the bottom of the tallest building. Although the city is covered by mud and sand, it has only flooded the surface, and the interior has not yet been invaded by foreign objects.

Therefore, after Li Yu was positioned, a spatial teleportation took everyone to the building that was suspected to be an energy center.

Of course, there is no light source in the interior of the building, so the Shining Crystal once again serves as a light.

Getting up close and personal with the city sunk under the sea, Fang Qianmo found that although the city as a whole is composed of metal, there are many other materials in its interior space.

"Now is not the time to observe this, let's first put the energy system online and get the city running."

"Then, you can research enough!"

Fang Qianmo pulled Lin Wanbai, who wanted to climb to the wall to study, and followed Li Yu, who was walking in front.

The positioning point chosen by Li Yu is still some distance away from the suspected energy center, which is also for the sake of safety, so you can't enter the center of the reactor with a teleportation, right?

That might have caused even more damage.
