Energy! Power! Yian felt excited when he thought that he seemed to have cracked the key to this device.

However, when he thought about it, he suddenly frowned again.

Since the group of people before him also found this instrument, there is no reason not to guess the function of this instrument, but judging from the appearance of this instrument, there seems to be no trace of activation before!

In other words, those people before either did not guess the function of this instrument or guessed it, but they could not replenish the corresponding energy for the instrument!

Yian estimated that the latter was probably most likely, so he frowned and thought, what exactly does this instrument use as energy?

The wind power and steam seem to be different. This round hollow ball looks like a container. Maybe it is used for water, but can such a little water be used as power?

Yian looked at the golden lines on the ground again. He felt that these golden lines covered the entire hall, which was definitely not accidental. If they were really regarded as integrated circuits, then the energy used by this instrument might be electricity!

After thinking about this, Yian suddenly realized that even if the people who climbed here before them knew that this instrument was powered by electricity, they might not be able to do anything about it!

But...Yian is different...

He took out a fist-sized thunder stone from his pocket!

Ever since he took control of Travilla's Thunder Stone transaction, Yian's Thunder Stone resources have increased. Arion and others are also using Thunder Stone to build an electric power city, but Yian uses Thunder Stone as a substitute for his own mind!

Now he basically carries a thunder stone with him, which can be used to use the skills of the Cannon Sister Card at any time.

And now, this thunder stone brought by accident can be used!

In 5's curious eyes, Yian held the thunder stone and slowly approached the instrument.

As mentioned earlier, when a stone like Thunder Stone approaches a metal conductor, it will cause discharge, but this is actually just the transfer of electrical energy in the ore. The discharge phenomenon itself is not dangerous. Otherwise, Valudo's Thunder Stone cannon uses Thunder Stone as attack energy, and the people inside will probably be overturned before the attack.

Yian could not explain this strange physical phenomenon, but he only needed to know how to use it. When the Thunder Stone slowly approached the instrument, a strange scene occurred, and slight light of electric light began to flash from the Thunder Stone and rushed towards the instrument.

The moment the electric light touched the instrument, the instrument indicator light on the base finally began to flash!

There was a constant sound of sizzling sounds. In Yian's palm holding the thunder stone, he kept whipping on the instrument as if an electric whip appeared! Then he was absorbed by the instrument!

5 Looking at this scene in surprise, she actually didn't expect that the thunder stone brought by Yian would come in handy here. After being surprised, she pointed to the hollow ball and said to Yian: "Look!"

Yian raised his head, but found that in the hollow ball, the electric energy of the thunder stone was constantly released. In the middle of the inside of the hollow ball, a bright spot flashing with electric light appeared!

That was the gathered electricity, and Ian immediately understood that the hollow ball was probably the same principle as Valudo's Thunderbolt Cannon. It can collect electricity and then condense a plasmon!

With the appearance of this plasmon ball, Yian saw the golden lines on the ground of the entire hall and began to emit light faintly.

"It's true! This instrument is powered by electricity!" Yian couldn't help but feel excited. He was 100% sure that the group of people who boarded the empty island before them probably hadn't activated the instrument because they didn't have the energy of thunder stone like Yian to charge the instrument! In other words, the secret of this city still exists and has not been discovered by others.

So now, Yian feels like picking up bargains. The treasures and secrets that his predecessors have not discovered have been found by himself. This feeling is quite comfortable.

"After this instrument is charged, some special secret room will appear, and it is very likely to be below this hall!" Yian thought so.

However, what surprised him was that after the discharge for a period of time, the thunder stone in Yian's hand suddenly turned into ashes!

After the discharge was over, the electrical energy contained in the thunder stone was consumed in such a short time!?

Yian looked at the dust in his hand in a little surprised, then looked at the instrument and found that the plasmon ball inside the hollow ball was about the size of a ping-pong ball, and the golden lines on the ground were still dim.

"This... this should be the reason for insufficient charging, right?" 5 asked.

"Yeah!" Yian nodded, and he thought of it, so he said to 5: "Retreat!"

After 5 retreated, Yian began to burst out with electric lights all over his body, put his right hand on his forehead, and then pulled it suddenly, and a ball of electric light was immediately condensed in Yian's hand!

"Lightning Gun!"

Yian threw the light in his hand at the instrument, and saw a dazzling blue light suddenly appear, and the lightning gun instantly hit the instrument.

A sizzling sound rang, and the electric light thrown by Yian was quickly absorbed by the instrument, and the plasmon sphere in the hollow ball suddenly increased a little.

"The electricity required is so high?" Yian said in surprise.

If it were someone else, I would be really impossible. Not to mention whether there is a thunder stone, even if there is one, the electrical energy required for this instrument will be quite large. According to Yian's estimate, it would take dozens or hundreds of kilograms of thunder stone to fill the hollow ball.

With so many thunder and rocks, it is still a problem to bring them up...

Fortunately, Yian is also a person with lightning ability now. The conversion of mind power into electricity is his strength. Since this instrument can absorb all lightning, Yian only needs to use the skills of the Cannon Sister Card to continuously attack it!

"Lightning gun, second shot!"

"Thunderstorm gun, third shot!"

Yian kept throwing electric lights at the instrument. Once the mind power value was gone, he would rest for a while and wait for the mind power value to return. As he continued to use the lightning gun to charge the instrument, the plasma ball in the hollow ball was also growing at a speed visible to the naked eye.

When Yian threw the 34th lightning gun, the plasmon ball condensed inside was finally about to fill the entire hollow ball! It was also at this moment that a huge vibration came from the ground again, and the ground around the hall actually began to shrink to the center in a whole piece!

When Yian and 5 saw this scene, they quickly stood together, tried to get close to the location of the instrument, and then watched the earth-shaking changes.

The underground of the hall was full of flat giant stones as thick as one or two meters, but these giant stones were stacked and sunken like some mechanism, and then collapsed continuously, and finally all gathered at the location where Yian and his feet were, turning into a huge stone pillar. Then, the stone pillar began to slowly sink again, carrying Yian and 5, and descending towards the exposed dark hole entrance like an elevator.

"No!" Yian thought in surprise: "This is on the empty island. The foundation will not be too deep, and it will not cause us to fall down, right?"

With this doubt, the two were gradually descended to the ground by the huge stone elevator, together with the instrument. Fortunately, Yian was worried about, and it only dropped for about twenty or thirty meters. Yian and the others reached the bottom.

What appeared in front of them was a basement with a larger area than the hall above. However, when I saw the scene inside the basement, Yian and 5 were both shocked!

The members of the Dragon Hunter Pirates who were watching the video through the phone bugs on Travilla Island below were anxious at this time, because just as Yian and his friends descended, the picture from the video bugs disappeared, as if they were blocked by something, so that they could not see what Yian and the others saw at this time.

Fresco! The basement is full of murals! And the murals are all depicted in figures that Yian and the others have never seen before!

In addition to the murals, the entire hall was filled with dense dwarfs, with a spear in their hands and a beard on their mouths, but these dwarfs were not living creatures. They stood in a daze, standing in a row in motion.

"What is this!? Are they residents of this empty island?" 5 looked at the dwarves in surprise and said.

"No, these are the real Sky Islanders!" Yian pointed to the patterns drawn on the mural and said. Many of the characters depicted in these patterns are characters with a pair of small wings behind them, so Yian understood that these are the real Sky Islanders!

As for these little dwarves who were like soldiers, Ian finally recalled what they were...

Rubbing the murals on the wall, Yian looked carefully at the pattern and guessed the content described above. The facts were as he thought, as these murals depicted the people of the Sky Island... No, to be precise, it was the past of the lunar people coming to this blue planet!

Ian remembered Eniro, and he knew that he might have seen something exactly the same as what Eniro saw after landing on the moon.

In a mural, Yian saw such a scene. In the picture, three winged people were crying, holding something like a balloon in their hands, saying goodbye to the people on a boat, and the people on this boat were the guys who looked like dwarfs in front of them!

With wings, they must be the people of the Sky Island, and these dwarves are the robots they made. As for the balloons held by the three Sky Island people, for some reason, Ian remembered the colorful balloons under the clouds of this Sky Island!

So Ian immediately understood that the so-called Baron Ruins Terminal was the first stop when the Moon Man landed on this planet!
