Energy! Impetus! Ian felt a thrill at the thought that he seemed to have cracked the key to the device.

However, after thinking 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 it being activated before!

In other words, the previous group of people either did not guess the function of the instrument, or they guessed the function, but they could not replenish the corresponding energy to the instrument!

Ian estimated that he was afraid that the latter was more likely, so he frowned and thought, what is this instrument used as an energy source?

Wind power? Steam? It doesn't seem like it, this round hollow ball looks like a container, maybe it is used for water, but can such a little water be used as power?

Ian looked at the golden lines on the ground again, he felt that these golden lines were all over the hall, it was definitely not accidental, if they were really regarded as integrated circuits, then the real energy used by this instrument was electricity!

Thinking about it this way, Ian suddenly realized that the people who landed here before them were afraid that even if they knew that this instrument used electric energy, they would be powerless if they didn't do it!

But...... Ian is different......

He took out a fist-sized thunderbolt from his coat pocket!

Since taking control of Travila's thunderbolt trade, Ian has more thunderbolt resources in his hands, and Arians is also using thunderbolts to build an electric city, but Ian is using thunderbolts as a replacement for his telekinesis!

Now he basically carries a thunderbolt with him, which can be used to use the skills of Sister Cannon's card at any time.

And now, this thunderbolt brought up by accident can be used!

Under BABY-5's curious gaze, Ian held the thunderbolt and slowly approached the instrument.

As mentioned earlier, the thunderbolt is a stone, and when it is close to the metal conductor, it will produce an electric discharge, but this is actually just the transfer of electrical energy in the ore, and the discharge itself is not dangerous.

This strange physical phenomenon, Ian can't explain, but he just needs to know how to use it, when the thunderbolt slowly approached the instrument, a strange scene happened, the slightest lightning began to flash from the thunderbolt, and rushed towards the instrument.

At the moment when the electric light touches the instrument, the meter indicator on the base finally starts to flash!

The sound of Zizi was endless, and Ian's palm holding the thundering stone was like an electric whip appearing, constantly whipping on the instrument! And then it was absorbed by the instrument as well!

BABY-5 looked at this scene in surprise, she actually didn't expect that the thunder stone that Ian was carrying would come in handy here, after being surprised, she pointed to the hollow ball and said to Ian: "Look! ”

Ian raised his head, but found that in the hollow ball, the electric energy of the thunder stone was constantly released, and in the middle of the hollow ball, there was a bright spot with flashing electric light!

It was the gathered electrical energy, and Ian immediately understood that this hollow ball was probably the same principle as Varudo's Thunder Roar Cannon, which could collect the electric energy and then condense the existence of a plasma ball!

And with the appearance of this plasma ball, Ian saw that the golden lines on the floor of the entire hall began to glow faintly.

"Sure enough! The instrument is powered by electricity! Ian couldn't stop the excitement in his heart, he was now 100% sure that the group of people who landed on this empty island before the two of them probably didn't activate this instrument, because they didn't have the energy of a thunderbolt like Ian to charge the instrument! In other words, the secrets of this city continue to exist and have not been discovered by others.

So now, Ian has a feeling of picking up leaks, treasures and secrets that no one has discovered before, but now they have been found out by themselves, this feeling is quite comfortable.

"After this instrument is charged, it is estimated that there will be some special secret room, and it is very likely to be under this hall!" Ian thought.

However, to his surprise, after discharging for a period of time, the thunder stone in Ian's hand suddenly turned into flying ashes!

At the end of the discharge, the electrical energy contained in the thunderbolt stone was consumed in such a short period of time!?

Ian looked at the dust in his hand with some astonishment, and then looked at the instrument again, and found that the plasma ball inside the hollow ball was only about the size of a ping-pong ball, and the golden lines on the ground were still dim.

"This ...... This must be the reason for the lack of charge, right? BABY-5 ASKED.

"Hmm!" Ian nodded, he thought about it too, so he said to BABY-5, "You go away!" ”

After BABY-5 retreated, Ian's whole body began to burst out of the Dao lightning, put his right hand on his forehead, and then pulled it suddenly, and a ball of electric light was immediately condensed in Ian's hand!

"Lightning Strike Gun!"

Ian threw the lightning in his hand towards the instrument, only to see a dazzling blue lightning flash, and the lightning spear hit the instrument instantly.

The sound sounded, and the electric rays thrown by Ian were quickly absorbed by the instrument, and the volume of the plasma ball in the hollow ball suddenly increased a little.

"How much power is needed?" Ian said with some surprise.

If it were someone else, I'm afraid there was really no way, not to mention whether there was a thunderbolt, even if there was, the amount of electricity to be collected by this instrument was quite a lot, according to Ian's estimate, I am afraid that it would take tens of hundreds of kilograms of thunderbolt to fill this hollow ball.

With so many thunderbolts, it's still a question how to bring them up......

Fortunately, Ian is now also a person with thunder and lightning ability, and converting his telekinesis into electricity is his strength, since this instrument can absorb all thunder and lightning, then Ian only needs to use the skills of the Cannon Sister card to continuously attack to recharge it!

"Lightning Shot, Second Shot!"

"Thunderbolt gun, third shot!"

Ian kept throwing lightning attacks at the device, and once the telekinesis was gone, he rested for a while, waiting for the telekinesis to recover, and as he continued to charge the instrument with the Lightning Strike Gun, the plasma balls in the hollow ball were also growing at a rate visible to the naked eye.

When Ian threw the thirty-fourth Lightning Strike Gun, the plasma ball condensed inside was finally about to fill the entire hollow ball! It was also at this time that there was a huge vibration on the ground again, and the ground around the hall began to shrink to the center in one piece!

When Ian and BABY-5 saw this, they quickly stood together, as close to the position of the instrument as possible, and then watched the world change dramatically.

THE BOTTOM OF THE HALL WAS FULL OF FLAT BOULDERS UP TO ONE OR TWO METERS THICK, BUT THESE BOULDERS WERE LIKE SOME KIND OF MECHANISM, CONSTANTLY STACKING AND SINKING, AND THEN CONSTANTLY SHRINKING, AND FINALLY ALL CONVERGED AT THE PLACE WHERE IAN WAS AT THEIR FEET, TURNING INTO A HUGE STONE PILLAR, AND THEN, THE STONE PILLAR BEGAN TO SLOWLY SINK AGAIN, CARRYING IAN AND BABY-5, LIKE AN ELEVATOR TO THE MOUTH OF THE EXPOSED DARK HOLE.

"That's not right!" Ian thought in surprise, "This is on the top of the Sky Island, the foundation won't be too deep, and it won't make us fall, right?" ”

With this doubt, the two of them were gradually lowered to the ground by the boulder elevator, along with the instrument, but fortunately, the situation that Ian was worried about did not appear, and it only fell twenty or thirty meters so that Ian and they reached the bottom.

What appeared in front of them was a basement that was larger than the hall above, but when they saw the scene inside the basement, Ian and BABY-5 were all stunned!

Far below on Travera Island, the members of the Dragon Hunter Pirates who watched the picture through the video phone bug were anxious at this time, because just when Ian and the others descended, the picture from the video phone bug disappeared, as if they were blocked by something, so that they couldn't see the scene that Ian and the others saw at this time.

Mural! This basement is full of murals! And the mural depicts all the characters that Ian has never seen before!

In addition to the frescoes, the entire hall was filled with a dense network of identical dwarfs, who had a spear in their hands and the same beard on the sides of their mouths, but these dwarfs were not living creatures, they stood in place and stood motionless in arrays.

"What is this!? Are they inhabitants of the empty island? BABY-5 looked at the dwarfs in surprise.

"No, these are the real Sky Islanders!" Ian pointed to the patterns painted on the mural, and many of the characters depicted in these patterns were figures with a pair of small wings on their backs, so Ian understood that these were the real Sky Island people!

As for the soldiers-like dwarfs, Ian finally remembered what they were......

Rubbing the murals on the wall, Ian carefully looked at the patterns and guessed what was depicted, and the fact was that they were just as he thought, the murals depicted the people of the Sky Island...... No, to be exact, the Moonmen's past to the Blue Planet!

Ian remembered Anilu, and he knew he was probably seeing exactly the same thing as Anilu had seen when he landed on the moon.

In a mural, Ian saw a scene of three winged men, tearful and holding a balloon-like object in their hands, saying goodbye to the people on a boat, and the people on the boat were the dwarf-like guys in front of them!

With wings, it must be the Sky Island people, and these dwarfs are robots they made, as for the balloons held by the three Sky Island people, I don't know why, it reminds Ian of the colorful balloons under the clouds of this Sky Island!

So Ian immediately understood, maybe this so-called Baron Ruins Terminal was the first stop when the moonmen landed on this planet!

The so-called terminal probably refers to the destination of the lunar people's uprooted trips......
