I am brushing up materials in One Piece

On the deck of the Gray Pearl, Kos breathed a long sigh of relief as he looked at the magnificent sea in front of him. He was surprised to find that he actually felt more at ease because he had left the land. Sure enough, monsters in the sea like Garp were more scary than the sea.

And as he let out his breath, the trial period of LV7's fruit ability finally came to an end.

"puff--"

A large mouthful of bright red blood spurted out from Kos's mouth, and at the same time, blood began to slowly flow out from his nostrils, corners of his eyes and ear holes.

Suddenly, Kos felt like the world was spinning. Every cell in his body felt like it had been exposed to the sun for 40 days with a weather forecast of degrees, and could no longer burst out with any vitality.

Then Kos swayed and fell backward.

"Kesi, what's wrong with you?"

Fortunately, Ace supported Kos in time to prevent the back of his head from coming into close contact with the deck of the Gray Pearl.

"That stinky old man is so cruel!"

Ace thought that Cos' current situation was caused by Garp, and looked towards the stern of the ship with an annoyed look on his face.

"No, this is my own fault."

Kos explained weakly.

He knew very well that the bleeding from the seven orifices was probably a side effect of the Devil Fruit's ability increasing to LV7. No matter how good it was, the side effects would be sour.

He only regretted that there were no side effects warnings in the instructions for use of "Yonko's Noise", so that he was caught off guard and was hit hard by the side effects.

"what happens!"

Deus also hurriedly put down the rudder and ran over. After seeing the terrifying appearance of Kos bleeding from all his orifices, he and Ace hurriedly sent Kos to the infirmary on the ship. In the end, only Michal was left on the deck to observe the situation on the sea surface. .

In the infirmary, Deus first checked the bleeding orifices, then listened to the heart sound, and finally judged that Cos was overloaded and overdrawn. It was serious, but it was not difficult to treat.

After giving Cos a bag of glucose and letting him have a good rest, Deus returned to the deck and continued to steer.

Ace stayed to look after Cos.

"Are you doing this because you want to catch that smoking bastard?"

Ace was not stupid, and he gradually understood that Kos's current injuries were mostly related to his sudden appearance of the Devil Fruit ability.

"I can only say that it will happen sooner or later. It's just brought forward because of Smoker."

Kos reluctantly shook his head with the little strength he had recovered.

Regardless of the appearance of Smoker or not, it is impossible for him to keep the "Proof of the Four Emperors", a prop that is guaranteed to unlock a skill for himself, and it will be a matter of time before it is counterattacked.

But Ace didn't think much of it.

"If only I were more powerful and could take out that smoking bastard, then you wouldn't be like this."

Ace stood up and paced back and forth in the infirmary a little anxiously.

"But that guy is so shameless that he is actually immune to attacks."

"You agree with this, right?"

Kos complained accurately.

In his opinion, Ace was actually the one who took advantage of elementalization. After all, Smoker's statistics were much higher than his. The two sides could go back and forth for so long and still be indifferent. Rely on one-hand elementalization.

"It seems like this..."

Ace awkwardly but politely touched the back of his head, and then remembered something like a flash of inspiration.

"But speaking of which, it would be great if I could master that armed haki you mentioned. Then I can deal with that smoking bastard and you don't have to take risks."

"You, cough, cough."

Kos coughed up a mouthful of stagnant blood and continued,

"You have actually mastered it, but you are not at a high enough level to be able to attack elementalized ability users."

From the battle between Smoker and Ace, Cos deduced that the LV3 Armed Haki should not be able to attack the elemental body, otherwise Smoker would not be able to attack Ace with only ten hands.

"is it?"

Ace looked at his hand, shook it briefly and then looked at Kos.

"Why can't I feel it?"

"You can recall the feeling when you were beaten by your grandfather. He used Armament Haki at that time."

Under the guidance of Kos, Ace closed his eyes and began to recall the bad experience just now.

After a while, Ace suddenly opened his eyes,

"I can feel it!"

After hearing what Ace said, Cos also raised his upper body slightly and looked at him, waiting for his next words.

But Ace's answer was——

"It hurts! It really hurts!"

"puff--"

A large mouthful of blood spurted out of Kos's mouth, whether it was blood that had accumulated before or was angered by Ace.

Wiping the blood from the corner of his mouth, Kos looked at Ace with a murderous look on his face.

"Who told you to think about this!"

Kos roared with all the strength he had finally recovered, and then withered like a raisin that had been exposed to the sun.

"Yes, sorry."

Ace panicked and apologized to Cos, who turned his head and ignored him, and then said helplessly,

"But grandpa's fists really hurt!"

Kos ignored Ace and just stared at the infusion bag silently.

Realizing his mistake, Ace scratched the back of his head, closed his eyes and felt it again.

Thinking back to how I felt every time I was hit by a punch, I thought about the mystery...

Gradually, he actually realized that something had penetrated into his body when Garp punched, making his body that could change at will solidify and unable to undergo elementalization.

Then he remembered what Kos said that he had mastered the armed color Haki, so he began to search for it in his body...

When Kos asked Ace to call Deus down and change the medicine three times, Ace still found no trace of the existence of armed haki. If Kos hadn't said that he had mastered it, he would have given up.

And since Kos doesn't know how to use Armament Haki at all, he can't teach Ace anything and can only let him slowly explore on his own.

After injecting three bags of glucose, Deus pulled out the needle for Cos, and called Ace away to let Cos lie down and have a good rest in the hospital bed.

Just when Kos was about to fall asleep in a daze, Ace's loud cheers suddenly came from the deck:

"We've arrived at the Red Continent!"

Kos, who was almost asleep, opened his eyes angrily, then jumped up from the hospital bed regardless of his injury, and then walked onto the deck in a menacing step.

However, Kos, who was originally full of resentment for his sleep being disturbed, finally understood that Ace would be so excited when he saw the scenery in front of the Gray Pearl.

Although the night was getting darker at this time, the crimson red earth continent in front of us was still so conspicuous.

No matter how expressive it is in comics and animations, it's still not as shocking as looking up in person. Cos raised his head and looked up, feeling only shock and the realization of how small he was and his inferiority complex.

Towering into the clouds can no longer be used to describe the height of the Red Earth Continent. It is as if it is connected to the sky, and the top cannot be seen at all.

The nearly straight cliff does not appear to be a natural formation, but who else but the uncanny workmanship of nature can create such a spectacular scene?

Even Michal, who never talked much, looked at the Red Earth Continent and nodded in admiration.

And Deus couldn't help but record the excitement of what he saw before him, so he took out his notebook and started writing.

Ace, on the other hand, clasped his hands into his fists and looked at the entrance of Upside Down Mountain not far ahead with great momentum.

"The great route, here I come!"
