I am brushing up materials in One Piece

The Gray Pearl rode the current and entered the canal on Upside Down Mountain from the entrance, taking the four people on board towards the Grand Line.

However, the length of this canal is much longer than expected...

In fact, if you think about it carefully, you should know that this canal is not that short.

The journey up and down the Upside Down Mountain can be regarded as two line segments, and these two line segments and the windless zone together form a triangle.

From the knowledge you can learn in middle school, you can understand that the distance up and down is definitely longer than the width of the windless zone.

Although there is no accurate data on the distance of the windless zone, judging from the fact that the windless zone can accommodate an island like Amazon Lily that carries a country, it is definitely more than ten or dozens of kilometers.

In other words, even if it takes the current that leads directly to the Grand Line, it will still take a long time for the Gray Pearl to cross the Upside Down Mountain.

At the beginning, everyone was still fresh and looked at the red continent on both sides of the ship excitedly. However, after driving for nearly an hour and the surrounding scenery had not changed, even Ace felt a little bored. .

More than an hour later, the sea currents below the Gray Pearl gradually stabilized, and the red earth continent that had always been monotonous finally began to appear a little green.

——They are going to the top of the mountain.

After a while, green vegetation appeared around, and dense woods could be seen ahead.

Ace, who was lying on the side of the ship and looking at his surroundings, suddenly stood up. He looked at Deus at the helm and asked, "Did you hear anything?"

"what?"

Deus raised his ears and looked around, but he didn't hear any other sounds except the sound of wind and the chirping of insects and birds from the woods ahead.

"That's a very cute 'gulu' sound."

Ace walked up and down the deck, looking for the place closest to the source of the sound.

When the Gray Pearl was carried by the waves and entered the woods at the top of the Red Continent, Ace finally found the direction from which it came.

"It's over there!"

Ace jumped off the Gray Pearl and landed on the tree-lined shore.

"Ace! What are you doing!"

Deus was so frightened that he immediately dropped the rudder and ran to where Ace jumped off the boat. He saw Ace waving his hands on the shore some distance away from the stern of the boat.

"Don't worry! I'll catch up!"

Ace's assurance did not bring Deus any sense of peace of mind. Just when he was hesitating whether to jump down and catch Ace or find a way to stop the Gray Pearl...

"Boom-"

A muffled sound came from the bow, and the Gray Pearl's hull began to shake violently.

Deus turned around and saw that the Gray Pearl had directly hit the bank of the canal on one side, and the hull was now bumping against the bank.

He had no choice but to run back to the helm and take over the helm again to avoid further damage to the Gray Pearl.

Kos and Michal noticed the abnormality and walked out of the cabin. Kos looked around and found that Ace was not around and immediately guessed the identity of the culprit.

"Where's Ace?"

he asks.

"He's ashore."

Deus, who finally got the Gray Pearl back on track, pointed to the woods on the shore and said with a wry smile,

"I didn't stop it."

Kos looked towards the shore and saw a figure that looked like Ace walking quickly through the gaps in the woods.

"What the hell is that guy doing again?"

"Does this happen often, Captain?"

Michal asked weakly.

"Not often."

Kos shook his head, then looked at Michal with a smile and said,

"Always. Congratulations, you are on the pirate ship. It will not be so easy to get off!"

However, Michal did not show any regret. Instead, he smiled knowingly.

"That captain is really an interesting person."

Kos felt that he, a normal person (who he thought he was), was so out of place in this world where freaks were normal people.

Just when Cos was thinking about whether he should usurp the throne and become the captain if Ace could not return to the ship, Ace jumped out of the woods, so Cos could only put his dream of being a captain on hold for the time being.

Ace, who was running towards the canal, was holding a dark unknown object in his arms. That seemed to be the reason why he jumped ashore.

After getting closer, Kos saw that it seemed to be some kind of animal, but it was curled up into a ball and it was hard to see the type, and it was not clear whether it was dead or alive when it was motionless.

"Wait for me!"

Ace held the ball of creatures and quickly chased after the Gray Pearl. Then when he got close to the Gray Pearl, he jumped up and wanted to jump onto the deck of the Gray Pearl.

Unfortunately, Ace obviously forgot that the Gray Pearl was not slow to climb the mountain with the current, so when he jumped into the air, the Gray Pearl was no longer where he planned to land.

"idiot!"

Kos raised his hand, and a chain flew out from his palm, tying Ace in mid-air, and then pulled him hard and brought him back to the deck.

"Sorry, sorry."

Ace knew that his actions had caused trouble to his companions, so he apologized to them as soon as he got on the boat, and then raised the creature in his arms to show them.

"But there's nothing we can do, this little guy is asking for help."

Only then did the three people on the boat see clearly that the one held by Ace was a feline.

The creature had two sharp fangs, and its head was larger in proportion to its body than that of ordinary cats.

But now that creature has completely lost its feline character as a top hunter. It is all skinny with only a layer of skin wrapped around the bones. The two fangs have lost their luster and the eyes are closed with only a thin slit. , from which we can see those eyes that are cloudy and lifeless but sparkling with the desire for life.

And if you look closely, you can see that the black color of the creature is not the color of its fur, but the color of the air-dried mixture of mud and blood. Its original fur color should be mainly milky gray.

Deus stabilized the Gray Pearl and went forward to check, and found that there was a serious wound on the creature's front paw that was deep enough to show the bone, and there were signs of ulceration.

"This is kind of bad!"

After completing the inspection, Deus returned to the rudder. At this time, the Gray Pearl had officially sailed to the top of Upside Down Mountain, where there was a huge lake.

Perhaps it is because the currents from all over the world converge here and cancel each other out, so the lake surface appears very calm.

So the Gray Pearl was moored on the lake, and Deus began to give first aid to the creature that Ace had picked up.

First, in order to facilitate treatment, Deus first shaved off all the hair on the creature's body, then cut off the necrotic part of the wound and bandaged it.

Finally, in order to replenish energy for the creature that had difficulty even opening its mouth, Deus also gave it glucose.

"I didn't expect that we would use so much glucose so quickly. I thought our bodies wouldn't use it. Fortunately, we brought some on board."

Deus, who had taken care of everything, sighed with laughter and tears,

"But I never imagined that one day I would be a part-time veterinarian. Fortunately, this little guy is in good health and the wound was neither seriously infected nor caused too much damage to the bones."

"That means Kodaz is fine."

Ace looked at the feline lying quietly on the hospital bed and smiled reassuringly.

－－－－－－off topic－－－－－

The performance of the canal in the comics is really outrageous. It rushed up in a moment, and then made a sharp turn and rushed down. It seemed that the total distance was only a few hundred meters.

But the pirate world can ignore the rules of physics, but it is impossible to violate even the basic laws of mathematics, right?

So I made some secondary settings.

The cat Kodaz (Lynx) existed in the original game, but since there was no specific description of where he met it, it was moved to Upside Down Mountain.
