National Navigation: I have an army of billions of Pokémon!

Wang Xuan drove the submarine and approached the entrance of the ruins carefully.

There were many sea fish swimming around.

There were also long streamers of seaweed overlapping and entangled here, making the diving environment very complicated.

Finally, they drove into the narrow bend, and Wang Xuan immediately became very alert.

It was here that the Mama fish had an accident just now.

Wang Xuan opened the hatch of the submarine and released the Aiya Ball Mushroom.

"Oh, the mushroom!"

"Go try what’s inside!"

""Hum~"

The Oya ball mushroom cried out and bravely jumped into the passage at the entrance of the ruins.

It is a mushroom, a grass-type Pokémon.

It moves in the sea water like a jellyfish.

It jumped into the passage in front, and a faint light immediately lit up inside.

Wang Xuan found the right angle and immediately took out the periscope to check the situation inside.

In the periscope's sight, the internal environment was presented.

The wall at the entrance of the ruins was actually inlaid with long strips of objects.

The source of light was these things

"Is this a light tube?"

Wang Xuan was a little confused. There were modern items in the ruins!

However, he was not sure whether it was a light tube.

There were too many attachments on it, and it was more than 100 meters away, so it was not clear.

The only thing that can be confirmed is that there are circuit devices in the ruins!

Wang Xuan was a little surprised:"The ancient people in this world also used electricity?" He looked inside again.

Oh, the ball mushroom has reached the end of the passage.

It screamed and told Wang Xuan that there was a door in front, it would not open it, and he could not get in.

Wang Xuan adjusted the direction of the periscope and wanted to take a look.

But the curvature of the passage was too large, and he could not see the situation inside clearly.

And...

Oh, the ball mushroom went in.

It was not attacked at all.

"strangeness"

"Only attacks Mama fish, not Oya ball mushroom……？"

""Mama, little fish, go in again!"

Wang Xuan decided to let the little fish go in again.

This time, he wanted to get a closer look with a periscope.

After receiving Wang Xuan's order, the little fish swam in immediately, although they were a little scared. The next moment, all the little fish swam in.

~~~

Chichichichichi~~~~~

Sure enough.

Just like before.

The Mama fish started to discharge electricity uncontrollably again.

One by one, the Mama fish madly hit the surrounding water surface with electric shocks.

The more they hit, the more scared they were, and the more electricity they released.

And Wang Xuan finally saw clearly.

They didn't seem to be attacked.

Instead, there seemed to be power storage devices in the walls on both sides of this passage!

After those power storage devices sensed the Mama fish coming in, they thought the Mama fish were power sources and passively activated the power storage mode.

At this moment, countless thin and dense electric wires spread out from the walls.

The Mama fish were covered by the electric wires, and the electricity in their bodies was being madly absorbed.

They thought those electric wires were attacks from the enemy, and they madly wanted to discharge electricity to kill the enemy.

But they were facing power storage devices, and the more they discharged, the harder they were sucked.

"grass!"

"These idiots!"

Wang Xuan was very upset and immediately shouted,"Stop it!"

"Stop discharging, come out!"

""Are you trying to use yourselves as generators? Fuck!!"

Wang Xuan shouted.

The fish immediately swam out from inside.

In just a moment, two fish were exhausted again. Their power was sucked dry.

The other fish were also very weak.

Wang Xuan almost vomited blood.

You idiots, you are being used as a mobile power source!

"Come up quickly and give you some sea crystals to eat!"

"Next time, don't be so silly and don't give them any attention!"

While scolding them,

Wang Xuan immediately took out a bunch of sea crystals for them to eat, so that they could quickly recover their energy.

This group of fish were very obedient, but a little silly.

While the fish were recovering, Wang Xuan fell into deep thought.

"There is electricity and power storage equipment in this relic. This is too abnormal."

"According to the book, even the most rubbish ruins are at least 1,000 years old."

"After so long, the energy storage device can still be used"

"In other words, the technology of ancient civilizations was more advanced than it is today?"

"Depend on!"

"If this is true, then the current level of social development has regressed, right?"

Wang Xuan was very puzzled. How could this be possible?

"Looks like I need to go in and explore."

"If there are design drawings and ancient books, it would be a great profit!"

Soon, the mother fish recovered.

Wang Xuan personally took them in this time.

After specifically reminding them not to discharge randomly, nothing happened.

"Oh My God!"

"The walls of this passage are actually made of crystals of polymer materials!"

"How far did the technology level of ancient society develop? It's really scary!"

Wang Xuan was amazed as he walked along.

This is just a small passage.

It is hard to imagine what kind of high-tech technology is inside this ruins.

……

In the passage.

Wang Xuan drove the submarine forward all the way.

This passage actually extends diagonally downward for more than 2,000 meters.

Wang Xuan estimated that its vertical depth should be about 700 to 800 meters.

The deeper you go, the greater the pressure of the sea water.

However, the various conditions in the passage also made Wang Xuan marvel.

Before coming here, Wang Xuan thought that the ruins were all ancient tombs, terracotta warriors and horses, etc.

But it turned out not to be.

At least this ruins is not.

More than 40 minutes later.

Wang Xuan swam to the end of the passage.

This is the innermost part of the entrance to the ruins.

There is no road ahead, only a circular hall.

Oh, Qiugu has arrived here first and is waiting not far ahead.

"Hum~"

"Hum~~~"

Seeing Wang Xuan's submarine coming, it jumped and called.

It said that this was the door, which was blocked by seaweed.

It took Wang Xuan to a place where seaweed was lush.

Wang Xuan shone the searchlight there.

He found that the door covered by seaweed was of a very high-tech style.

It was not an old wooden door, nor an aluminum alloy anti-theft door.

It was like the door in science fiction movies, where you need to scan your fingerprint and pupil to enter.

"Yeib, you go down too!"

"Hey, Enchantress, Leafeon, you two, clear the seaweed around this door immediately!"

""Mom, Xiaoyu, go search every corner of this circular hall to see if there are any keys or mechanisms!"

Wang Xuan quickly assigned tasks to the Pokémon.

There was no telling what was behind this door.

Wang Xuan became more and more curious.
