----------
The martial skill that condensed the terrifying sword power transformed into a black and red mammoth sword energy under Alex's display. It blasted towards the ancient robot with the momentum of pulling mountains and filling seas!
BOOM!
The huge trembling sound resounded through the entire cave, making the surrounding environment shake violently.
At this moment, Loki didn't care about the secret place that kings had always guarded. He was shocked by Alex's unique display of their giants' technique and worried that this level of attack would collapse the cave.
Little did he know that Alex had actually held back. After all, he wasn't sure whether the ancient robot could withstand his full power, so he had restrained both his dominance and armed techniques.
But now it seemed he had worried too much.
Even though it was directly hit by Hakoku, the ancient robot seemed to have been injected with some kind of energy. The empty eyes that had been silent for many years were re-lit.
However, it appeared to be damaged, or perhaps the injected energy was insufficient. The eyes of the "resurrected" ancient robot only flickered briefly before losing all consciousness and falling dark again.
Seeing this, Alex's expectations rose.
This technology was indeed the product of advanced civilization from the past!
Alex had experienced the effect of robots converting attacks into energy in the Sky Kingdom before, because Pluton, one of his trump cards, also possessed this ability.
ZIZI!
Black and red conqueror's Haki swirled like flowing water, crazily entwining with Akazakura and Ame no Habakiri under the king's will.
Once again, Alex held the two swords together, combining Haki and blade. The powerful and unstoppable attack slammed down on the ancient robot again.
BOOM!
Under the interweaving of attacks, an inexplicable roar of thunder could be vaguely heard.
The sharp, ear-piercing blast swept through with tremendous force!
The whole cave shook again.
Yet the seemingly precarious signs of collapse were just an illusion. Not even a piece of gravel fell from above.
This allowed Loki to calm himself somewhat, and after moving closer to Alex, he joined him in examining the strange ancient monster.
With the addition of several layers of power, the resulting energy effect was much greater than before.
Under the attack of even more terrifying power, the ancient robot's body made of mysterious metal began to show signs of cracking.
The massive energy absorption made the robot's power levels much higher than previously measured.
The next moment, some mechanism seemed to activate.
An inexplicable "click" sound of turning gears echoed in the cave.
While the ancient robot remained motionless on the ground, a phantom-like light appeared in the deeper part of the cave that could only accommodate two giants. It looked like a portal to a different space.
Without hesitation, Alex walked forward, his body passing directly through the phantom light.
As before, after Alex stepped through, a few fire lights appeared in the darkness and spread rapidly, though this time they soon stopped expanding.
Alex looked around. It was still an underground cave.
Compared to the slightly narrow place before, this space was indeed a cave of somewhat exaggerated proportions.
Even the huge giants would appear small here.
In this space, there were many deserted and rusty relics, carved totems, and numerous stone tablets covered by dust.
Seeing this, Alex contacted Robin via Den Den Mushi. At the same time, he stretched out his index finger. Under the action of his Devil Fruit power, ten small tornadoes soon formed at his fingertip.
Alex swept his hand, and the huge cave immediately filled with strong winds, purposefully clearing away all the dust.
Alex could avoid these dust clouds himself, but Loki, who had followed him inside, couldn't help covering his face and mouth, waiting for the wind to quickly subside.
After the cleaning, the contents of many stone tablets were visible once again.
Alex first examined a huge stone tablet standing in the center of the space. There were no words engraved on it, but many pictures were drawn.
Since he had summoned his archaeologist to come, Alex didn't intend to decipher it himself. This required professional expertise.
Not long after, using her Flower-Flower Fruit powers, Robin quickly arrived in the cave following Alex's directions. Under his instruction, she began to examine the huge central stone tablet.
"This appears to be an ancient pictographic text... It seems to record the history handed down by the giant family."
After this brief explanation and Alex's nod, Robin quickly translated the content of the pictographs.
"A long time ago, there was a country called the Great Kingdom, and various races lived within it, with the giant race being one of them. Then a war broke out that swept the entire world. The final result was the defeat of the Great Kingdom, with the elite forces of various races suffering devastating blows. The giants eventually migrated here."
"With the establishment and growth of the victorious World Government, Elbaf no longer maintained any connection with the outside world."
Alex raised an eyebrow.
Even though the giants had become their allies, he knew Robin hadn't revealed everything.
Because on the paintings of the stone tablet, there was also a figure waving a fist the size of an island, with that distinctive hairstyle and a big laughing smile. It was obviously Nika, or "Joy Boy."
Loki, unaware that Robin was hiding something, stared blankly at the stone tablet, completely shocked to learn that the World Government had been the enemy of their clan long ago.
But more than this history, Loki cared about the huge secret he had mentioned earlier—one that could match or even surpass the reputation of Elbaf's Spear.
"So, is that all there is to it?" Loki asked.
Robin withdrew her gaze from the huge central stone tablet and said, "Essentially, yes. The content primarily concerns the past history of the giants and their kingdom. Of course, this is just the central stone tablet. There are many others related to historical records here. There may be additional information and secrets waiting to be discovered."
Looking at the vast amount of information contained in this space, especially the history related to the Great Kingdom, Robin's interest as an archaeologist was rarely so piqued.
"I don't know what secrets remain hidden here, but Loki, the huge secrets you mentioned do exist," Alex said.
As the giant stepped forward, Alex brought out a stone tablet from a relatively remote corner. Under the light of the flames, it was completely different from the red stone tablets elsewhere. He placed it firmly in the center.
