Solar shares his experience with Lunar, speaking of the seventh thing in the queen's wills, which is to slay a seven-head shark under sea bottom.
Solar: Until we dived in the foggy sea where ghost boat sank, we never realized there's a crucial problem, that werewolf couldn't breathe under water. Until we lost oxygen, we never realized how essential oxygen was. Until we were almost faced with death out of oxygen, we never realized how good being alive was.
Lunar listens to his experience to slay a seven-head shark under sea bottom, and wonders which method did he use to breathe under sea bottom?
Lunar: It's essential to breathe oxygen for most of creatures; it's natural to breathe under water for aquatic beings; it's hard to breathe under water for terrestrial beings. As terrestrial being, you couldn't be able to breathe under water. But as smart being, you could be able to find a way, right?
Solar: Fish had fish gills, crab had fish-liked gills, and turtle had special skins. We didn't have fish gills, as fish did; we didn't have fish-liked gills, as crab did; we didn't have special skins, as turtle did. But we had Potion of Transformation, which allowed us to transform our ears to either fish gills or fish-liked gills or special skins.
Lunar: Tuna can dive down to 600-900 meters; salmon can be found in the upper 200 meters; yellowtail can be found in water above 100 meters. Not all kinds of fishes can dive down to sea bottom. Only demersal fishes can be found in sea bottom, and many the others can't. What kind of fish gills did you use to dive down to sea bottom?
Solar: Fish gills of snailfish. Most of snailfishes can be found at a depth of 6000 meters, and some of them can dive 1000 meters deeper. With fish gills of snailfish, we could be able to follow ghost boat's lead and dive down to sea bottom.
Lunar: Five hundred years ago, there's a seven-head shark, who suddenly attacked the Ship of Princess. His sudden attack got my boats sunk; his sudden attack got my friend and pirate crew drowned; his sudden attack got himself judged life imprisonment in the seal of sea bottom. What did you witness, when you got there?
Solar: Under sea bottom, 20000 feet under the sea, we witnessed the battle between ghost boat and seven-head shark.
Lunar: What kind of battle was it like?
Solar: It was like the battle between King Kong and Godzilla.
Lunar: May you please tell me about the details?
Solar: Seven cannons held by seven captains and sixty-three guns held by pirate crew, aimed at seven-head shark's seven heads, firing from one mile away outside the seal of sea bottom. Seven-head shark was the target with no where to hide.
Lunar: The Ship of Princess was not armed with seven cannons, until seven cannons were reinstalled from seven pirate's boats to the Ship of Princess. The Ship of Princess was not so massive, until it was enchanted to become a ghost boat, which could be able to swallow the other pirate's boats and grow its seize. The Ship of Princess was not so powerful, until it evolved through many times in five hundred years.
Solar: Compared with seize, both sides were the same seize; compared with heads, ghost boat got seventy heads, which was ten times more than seven-head shark; compared with strength, ghost boat's strength was growing stronger and stronger, while seven-head shark's strength was getting weaker and weaker.
Lunar: Seven-head shark had seven heads with the same amount of massive mouths grown with sharp pointed teeth. But unfortunately, he didn't have the same amount of smart brains. His sudden attack set me thinking if he got any brains inside his heads. If he got any brains inside, he would have thought about the consequences.
Solar: Life imprisonment was a harsh punishment, but it was not a proper punishment that he ought to deserve. Death sentence was the only way to revenge for the pirate spirits, and it was the only proper punishment that he ought to deserve.
Lunar: Five hundred years ago, I judged him life imprisonment, because I was too nice to everybody. I should have judged death sentence. Which was why I wanted you to slay a seven-head under sea bottom.
Solar: It turned out that I was not sent there for pirate's treasures, I was sent there to execute seven-head shark's death sentence.
Lunar: Seven-head shark once was a one-head shark, evolved through six times to be a seven-head shark. Each time he evolved through, he grew one more head. Each time he evolved through, his seize became twice as huge as before. Each time he evolved through, his strength became twice as powerful as before. After evolving through six times, seven-head shark had become 64 times greater than a natural shark.
Solar: With this massive body, he could be able to swallow the whole white whale with one mouth; with this massive body, he could be able to get a small island sunk under the sea with his tail; with this massive body, he could be able to bite a massive dragon.
He could probably swallow me with one mouth, even when I was a huge wolf.
Lunar: If you knew how to do reduction magic, you could be able to reduce his seize from a massive shark to a small fish. If you knew how to do transformation magic, you could be able to transform him into a frog. If you knew how to do forbidden magic, you could borrow the power of ocean to destroy him. But unfortunately, it would take years of reading magic books to do that kind of magic. You must have found a way, right?
Solar: Yeah. After getting fired by ghost boat's cannons and guns, seven-head shark would open his mouths and roar at ghost boat. I took this advantage, and threw some potions in his mouths. Which included the Potion of Reduction and different kinds of poisonous potions, which reduced him from a massive shark to a normal shark, which offered him different kinds of negative effects.
Lunar: He was still too powerful for you, even when he was poisoned.
Solar: After getting beaten over one thousand rounds at the colosseum, I finally won once under sea bottom, with the price of getting two ribs broken.
Lunar: How were pirate spirits?
Solar: They returned to where they belonged.
