I am brushing up materials in One Piece

Seeing Ace take the initiative to dive into the lava, Kos was relieved, because if he was really hurt by the lava, he would never react like this.

At the same time, he began to sigh. He didn't expect that Akainu, who looked honest and honest with a Chinese character face, would not say a few truths. It was obvious that one of the two people was not elementalized in order to protect Luffy, and the other relied on strength and armed domineering. The defense was broken, but in the end, he had to pull the upper and lower fruits to show that his victory was natural.

When Kos was finally relieved, Ace had already swam around in the magma. He stuck his burning upper body out of the magma and waved to Kos.

"Cos, do you want to come down and try? Swimming here won't make you weak like in the water."

"Ha ha……"

Cos was already used to Ace's lack of strength, and he didn't even bother to explain that not everyone could swim in magma with thousands of temperatures as warm water like him.

Seeing that Kos did not respond to his invitation, Ace did not wait any longer and continued to enjoy the long-lost swimming experience.

After he had enough fun, Ace finally recalled his true purpose of coming here.

So he swam up and down in the magma in order to feel the changes in temperature, because in terms of physical sensation, the temperature of the surface magma did not make him feel "hot". Only the deeper magma could bring "warmth" and the like. Feel.

However, the temperature change of only two to three hundred degrees is not very obvious to Ace, whose body is a flame. It is not even as obvious as the change in water temperature after turning the switch that adjusts the water temperature by one degree when taking a bath.

etc! What would happen if the flames on the magma were absorbed?

A bold idea emerged in Ace's mind.

So he first surfaced on the surface of the magma, then opened his hands and called the "fire" around him to come to him.

Hot and dazzling light points slowly rose from the slowly flowing and boiling magma and flew towards Ace. At the same time, the magma quickly began to cool down and solidify...

Not long after, the magma that was boiling and bubbling just now turned into a rock-like material as dark as ink.

"So that's what happened!"

Ace was very surprised by this result. The changes in the magma allowed him to finally understand vividly how much influence temperature has on objects.

"Whoosh-"

A weird sound like a pressure cooker blowing air came from beneath Ace.

"what is this?"

Ace looked around, but all he could see was the pitted black surface after the magma solidified.

But Kos, who was watching all this from above, immediately realized what was going on.

"Come out quickly! Danger!"

Kos shouted loudly.

Originally, this volcano was about to erupt, and the pressure inside was definitely not small. However, Ace allowed the surface magma to solidify and added a layer of cover to it.

As a result, the pressure that could have been released slowly was accumulated. The weird sound just now was a manifestation of excessive internal pressure.

"Um???"

Ace felt that there was no danger, but he still pulled out the elemental form of his body from the solidified magma.

But when he stood on the black magma solidification before he could take the first step...

"Boom--"

As if he was finally able to sneeze after having a stuffy nose for a long time, the crater where Ace was located erupted happily.

The pressure accumulated because of Ace's attempt to die was released in one breath, not only ejecting a far larger amount of magma than usual, but also sending the layer of solidified magma high into the sky.

Kos quickly turned around and ran down the mountain, but it was more like jumping down instead of running.

Kos, who landed at the foot of the crater, looked up. The first thing he saw was the magma slowly dripping down the bare volcano surface. Looking further up, he could see the hot magma and half of it being thrown into the air. Large rocks in a molten state...

And, a huge black rock-like object, and you can see slowly dripping magma at the bottom of the huge rock.

On top of that rock that was still flying into the sky, there was probably Ace who had not been able to escape, enjoying the same flying service as Lord Kaz.

Fortunately, the volcano in the small garden didn't have much vitality. Even the "sneeze" that had been held in for a long time was not very powerful. The rock carrying Ace flying into the sky soon stopped rising.

The rock flipped several times as it fell, allowing Kos to see Ace burning brightly on it.

"Yo ho!"

Ace's excited shouts came from the air. It seemed that being thrown high and then dropped from the air was just a thrilling and interesting experience for him.

Of course, for Ace who can elementalize, pure physical damage such as falling from a high altitude does not pose a threat.

However, Kos felt that even if Ace didn't eat the Shao Shao Fruit, he would still be able to shout excitedly when experiencing this situation.

Ace's free-fall experience didn't last long. He and the rock solidified by magma soon hit the jungle near the crater heavily.

After Kos rushed over, he found that Ace was heating the black rock and turning it back into magma little by little. However, from the time he landed until Kos arrived, he had only turned a rock the size of the Table of Eight Immortals into magma.

After seeing Cos coming, Ace immediately stopped what he was doing, picked up a ball of magma and showed it to Cos.

"I know how to exercise in the future."

As he spoke, the magma in his hand cooled rapidly and turned into a black rock, then gradually turned red and began to melt.

"Although I don't know how the temperature has increased, as long as I keep melting this stone and wait until one day I can melt it faster, then it means that the temperature of my flame has increased."

Seeing that Ace was safe and sound and had found a way to exercise his abilities, Cos was relieved and relieved that some of his children could finally complete their homework on their own initiative.

But instead of praising Ace, he put on a bad face.

"First explain to me why you suddenly jumped into the lava? Don't do whatever you want just because you are the captain! Bastard."

Ace's behavior of jumping into the potentially dangerous magma without saying a word made Cos very angry. Today he dared to jump into the magma by himself, but tomorrow he might not dare to lead everyone into the deep sea whirlpool.

This captain's overly authoritarian and dangerous attitude of disregarding others must not be tolerated, so now Cos must make Ace understand that what he just did was wrong.

"I just want to prove to you that I will never be killed by mere magma."

Ace smiled and slapped the lava in his hand to his chest, but it did not cause any harm to him. After that, Ace's smile became even brighter.

"I am your captain, and I will not die easily before I take you to the other side of your dreams."
