The villainous young master just wants to live a Buddhist-like life.

　Dark's mind raced, but encountering the "Sword of the Mountain Giant" in this secret chamber was entirely unexpected. His understanding of the "Sword of the Mountain Giant" was extremely limited. He couldn't even discern whether the legend was true or false, so how could he possibly deduce what it wanted?

　So, let's try a different approach.

　What could the "fossilized pterosaur" bring it?

　But what else does the "Fossil Pteranodon" possess besides "Ancient Power"?

　It cannot attract wealth and treasures like "Ebu", nor can it enhance the fruit like "Huhu".

　Even if the "Mountain Giant's Sword" wanted to find a new master, it couldn't be the "Fossil Pterosaur".

　I can't figure it out. I can't figure it out.

　I can't understand it at all!

　Dark looked at the "Fossil Aerial Dragon," then at the "Mountain Giant's Sword." The "Ancient Power" of the "Fossil Aerial Dragon" had increased to 45%. But other than that, there was no increase.

　The rock-type energy absorbed from the "Mountain Giant's Sword" is only temporarily stored in its body. It will naturally dissipate into the air once it returns to the magic card—which is clearly not in the "Mountain Giant's Sword's" interest.

　Unless the "Mountain Giant's Sword" is so ancient that it has no idea what a magical spirit is...

　That is certainly very possible.

　After all, it should spend most of its time sleeping in this secret room.

　This sudden appearance was probably a reaction to something it sensed from the "fossilized pterosaur".

　But what exactly did it sense?

　45%.

　46%. 47%. 48% 49%.

　Just as the "Fossil Ape Dragon's" "Petrification Power" was about to exceed 50%, a change finally occurred!

　On the blade of the "Mountain Giant's Sword," especially near the tip, the number of cracks suddenly increased.

　As if its energy consumption had finally reached a certain limit, countless cracks suddenly appeared on that section of the sword, chunks of rock fell off with a "crash," and the rocky outer shell on that section of the sword became thinner and thinner.

　Dark stood under the wind barrier that Professor Sylph had casually set up, looking up at the section of the sword.

　Right before his eyes, the section of the sword that should have been "encased in rock" suddenly cracked open in large sections, collapsing from the tip downwards and disappearing completely in the blink of an eye!

　Dark's pupils contracted sharply, and he exclaimed in astonishment, "Empty!" Professor Sylph was equally surprised, her brows furrowing deeply.

　But after the rocky outer shell of the sword fell off, there was no sword inside at all!

　“Professor!” Darke suddenly said.

　Professor Sylph waved her hand, and a gentle breeze arose, allowing the two to ride the wind and fly into the air, arriving above the broken and shattered sword.

　Looking down from the broken crack, where the sword blade should have been, there was absolutely nothing there.

　This "Mountain Giant's Sword" was unexpectedly just an outer shell—"No!"

　"Dark suddenly said."

　"This is an invisible sword!"

　“Just as I thought,” Professor Sylph said softly.

　"This holy sword is not just a 'Rock' type." Holy swords with dual attributes do exist.

　Moreover, there exists something that, like that "scabbard," can absorb and fuse the essence of the "Holy Sword."

　There must be other holy swords in this world that possess multiple attributes or are composite.

　After seeing the inner workings of the "Mountain Giant's Sword," Professor Sylph considered a possibility.

　Dark shared almost the same idea as her; they simply glanced at each other and reached a consensus.

　simply put.

　The "Mountain Giant's Sword" is a legendary holy sword made of rock, larger than a mountain peak.

　But the "Mountain Giant's Sword" that now appeared before them was only about ten meters tall.

　Although its size also qualifies it as a "giant sword," it still doesn't match the legend.

　Assuming the legend is true, could the "Mountain Giant's Sword" be a (holy sword) capable of freely changing its size?

　This possibility does exist, but it is actually quite rare.

　Now it seems that the other possibility has more potential. The "Mountain Giant's Sword" is actually not intangible; its blade is entirely made of rock-based elements or piled-up rocks.

　The reason why its size in legends does not match its current size is simply because the amount of rock and elements used to forge the sword is different.

　But if that's the case, what exactly is the other attribute of the "Mountain Giant's Sword"?

　Is it a Psychic-type that can gather rocks together, or a formless Ghost-type?

　Or perhaps the mysterious and unpredictable fairy type.

　Dak opened his senses and felt carefully.

　Without the outer rock covering, the true nature of the "Mountain Giant's Sword" was finally revealed.

　Dark quickly sensed the aura of the "Ghost" type. He immediately knew that this should be a "Holy Sword" somewhat similar to the "Single Sword Sheath".

　However, "Single Sword Sheath" is a Steel/Ghost type.

　This "Mountain Giant's Sword" is a Rock/Ghost type weapon. So, it's channeling its own Rock energy into the "Aerodactyl." Is it perhaps preparing to possess the "Aerodactyl" like a ghost, as if in preparation for doing so?

　More doubts arose in Dak's mind.

　If it's this level of "possession," he's not worried. Once the summoning is dispelled, it can only possess a wisp of magical energy. Even if it follows him into the magic card… wouldn't that be like a lamb entering a tiger's den?

　Not to mention there is no precedent for this, even if it breaks the precedent, it will only be walking into a trap.

　Dark wasn't afraid at all.

　He glanced at Professor Sylph, who nodded slightly, suggesting that the two had quietly reached an agreement once again!

　This "Mountain Giant's Sword" truly knows nothing about the magical elves!

　The changes are intensifying.

　The "Ancient Power" of the "Fossil Pterosaur" has exceeded 50% in the blink of an eye, and it continues to rise.

　The ancient power contained within this "Mountain Giant's Sword" is so immense!

　However, once it exceeded 50%, the disintegration speed of the "Mountain Giant's Sword" also suddenly accelerated.

　Dark and Professor Sylph hovered in the air, watching as the rocky blade of the "Mountain Giant's Sword" collapsed rapidly like a landslide.

　Just two or three minutes later, the blade had collapsed down to the hilt!

　At this moment, the energy absorbed by the "Fossil Pteranodon" suddenly changed, gaining a cold and eerie quality.

　As expected, "Mountain Giant's Sword" also took the opportunity to pour its own Ghost-type body into "Fossil Aerodactyl"!

　Dark held the magic card, carefully observing the changes in "Fossil Aerial Dragon," determined to forcibly cancel its summoning the moment the anomaly appeared.

　However, no abnormality ever occurred.

　When the Ancient Power of the Fossilized Pteranodon finally reached 56%, the rocky blade of the Mountain Giant Sword finally disintegrated completely.

　And it itself was completely integrated into the body of the "fossilized pterosaur". The real change only suddenly appeared at this moment.

　The fossil pterosaur, which had been greedily absorbing the "ancient power," suddenly stopped.

　Just when Dark thought it had been possessed by the "Mountain Giant's Sword," the data on the "Fossil Wyvern" magic card suddenly started jumping around randomly.

　The most noticeable fluctuations were in the values ​​of magic power, attack, and defense! Especially magic power and attack, which at one point jumped to over 10,000!

　Dark was so surprised that he abandoned his plan to immediately recall the "Fossil Aerial Dragon" into the Magic Card.

　Suddenly, the thought of "observing for a while longer" arose in his mind.

　Upon closer inspection, he discovered that layers of rocky shells had suddenly appeared on the "fossilized pterosaur's" body.

　The "Fossil Pterosaur" had actually activated the "Fossil Ghost" ability! It crossed its wings and stood still, transforming into a giant stone statue. However, the rocky shell that appeared on its body did not stop growing.

　When the six-second invincibility period ended, the rocky shell had grown to the point that it completely covered the outline of his body.

　And it remained motionless!

　Dark looked at the "Fossil Pterosaur" that had turned into a stone statue with a complicated expression. When it became completely still, the passive effect of "Silent as an Ancient Tomb" was automatically triggered, and the aura that spread outwards concealed its aura.

　Its body, already encased in a rocky shell, gradually disappeared from view. This reveals that the layers of rocky shell were not part of its body.

　It was at this point that Dark finally understood the specific mechanism of "Silent as an Ancient Tomb".

　He was also surrounded by an aura, which made his body invisible.

　However, this invisibility was not complete in his field of vision; he could still see some nearly transparent outlines.

　This must be a special field of vision influenced by the aura. And it was under these circumstances that the "Fossil Aerial Dragon" was encased within a gradually forming giant rock egg!

　A transformation is about to happen!

　This could not possibly be a transformation brought about by the "power of fossils".

　While 56% of the "Fossil Power" is already a lot, it is impossible to "restore it to its ancient form" as long as it is less than 100% for even a single day.

　In that case, the transformation before our eyes could only be caused by the "Sword of the Mountain Giant"!

　Professor Sylph landed slowly with Dark.

　The two stood on a boulder, both looking solemnly at the giant rock egg.

　Professor Sylph finally spoke, "Is this change good or bad?" Dark wanted to say, "How should I know?", but what came out was, "The egg is the beginning of life. If the 'Mountain Giant's Sword' weren't a sword, I would suspect it was trying to be reborn through a body."

　Professor Sylph said, "Even a sword could be." Dark sighed and said, "It seems so."

　He had not lost control of the "Fossilized Pteranodon." However, the changes brought about by the "Mountain Giant's Sword" had clearly interfered with the essence of the magical spirit.

　The entire magic card underwent a drastic change as a result.

　Dark had to admit that he was somewhat curious about what the outcome of this change would ultimately be.

　Fortunately, the entire transformation process did not last too long.

　They waited for less than five minutes before a long crack appeared on the enormous rock egg.

　Immediately afterwards, the crack opened up from the inside out, and the entire outer shell of the giant rock egg exploded with a "bang".

　Professor Sylph quickly waved her hand, summoning a wind barrier to block the flying eggshell fragments.

　Only after all the fragments had fallen did she remove the barrier. Dark grabbed the magic card and looked towards the location of the giant rock egg.

　Only the bottom ring of the eggshell remained, and the "Fossil Pterosaur" still stood in the same spot like a stone statue, seemingly unchanged.

　But three stone statues suddenly appeared beside it!

　The three stone statues were only 1.8 meters tall, a mere fraction of the size of the five-meter-long "fossilized pterosaur" itself, a difference between a juvenile and an adult.

　However, they are not small in appearance and are basically the same as the "fossil pterosaur".

　"Is it just three more small [Fossil Aerial Dragons]?" Dark frowned slightly, looking down at the magic cards in his hand.

　The three measurements that were fluctuating wildly just now have now completely stabilized.

　Moreover, it did not experience the explosive growth that Dak had expected, which inevitably left him somewhat disappointed.

　But looking at the card again, there are indeed two smaller pterosaurs next to the original pterosaur in the card design.

　"Wait, two!"

　Dark suddenly looked up, his eyes turning golden in that instant.

　Under the "Eye of Truth's" gaze, the three small "fossil pterosaurs" were revealed in their true forms.

　"What's wrong?" Professor Sylph asked quickly.

　Dark said, "Of those three smaller ones, two are progeny forms of the 'Fossil Pterosaur,' and the other... is a real one!"

　Professor Sylph immediately realized: "That's the Mountain Giant's Sword!" Dark nodded and said, "It seems so!"

　At that moment, a sudden flash of inspiration struck him, and he recalled some information: "Wait, I suddenly understand."

　Professor Sylph asked, "Do you understand the principle now?"

　Dark nodded and said, "It seems I've been overlooking something all this time. Besides the potential brought by the 'Ancient Power,' this 'Fossil Pterosaur' has another undiscovered potential."

　After saying that, Dak jumped off the boulder and strolled toward the "fossil pterosaur".

　He finally remembered where two of the four special moves possessed by the "Fossil Pteranodon"—"Fossil Demon" and "Silent as an Ancient Tomb"—came from.
