I am brushing up materials in One Piece

In the following days, Ace no longer continued to charge into the sea currents, but planted a few branches on the beach and began to practice his ability to burn fruits.

At first, he couldn't even control his body to stop burning. It wasn't until the data Cos saw that the level of the Burning Fruit changed from LV1 to LV2 that he basically got rid of uncontrolled self-burning.

By the way, this process only took Ace half a day. It seems that it is relatively easy to improve his Devil Fruit skills.

It's just that the flames emitted by LV2's Burning Fruit can only simply cover Ace's body, and the distance emitted is only about one meter, which is far from being used to drive the thrusters.

Afterwards, Ace began to try to use flames to shoot branches stuck on the beach. During this period, Kos and Deus were busy making small boats powered by flames.

Unlike making a raft, just making the core driving device requires a lot of energy, and the most important thing is that the only raw materials they can get on the island are basically wood, and the driving device needs heat-resistant materials, at least it will not be burned by flames. Only ignitable materials will do.

So Kos donated all the iron sheets on his body. Because the iron sheets were not very thick, it was relatively easy to process. The parts that were really difficult to process were heated and softened by Ace's ability.

In this way, with the continuous efforts of the three of them, the driving device was gradually completed, and Ace's Devil Fruit skill level reached LV3. The interaction between the two was able to produce quite good advancement.

After making certain adjustments to the driving device, the manufacturing of the hull began. Because Dios had heard that the waterproof and moisture-resistant ability of wood would be greatly improved after carbonizing the surface at high temperature, so during the hull manufacturing process Ace couldn't just exercise his abilities leisurely, but the process of processing wood still exercised his abilities to a certain extent.

By the time the boat was completely completed, half a month had passed, and Ace's Burning Fruit level had successfully reached LV4, which allowed him to release a huge flame that instantly evaporated a small area of ​​seawater.

"Isn't your mastery speed a little too fast?"

Seeing Ace's rocket-like fruit ability increasing speed, Kos couldn't believe it. You must know that Bucky the Clown had already eaten the Shashuo Fruit when he was on Roger's ship. Ace was not even born at that time. As a result, Ace has only eaten the Shashuo Fruit for half a month, and he has already mastered the fruit's ability. Reached the same LV4 as Bucky. For a moment, Kos didn't know whether Bucky was too slow or Ace was too evil.

However, when he saw the fierce flames spraying out from the tail of the boat and generating a strong propulsion force, which almost caused the boat to break away from the wooden frame that supported it, Kos felt that the monster point was actually pretty good.

After Deus recorded the data in his notebook, he nodded and signaled Ace to stop. Ace stopped releasing the flames and jumped out of the boat on the beach.

Kosi leaned over and asked, "How is it?"

Deus closed the notebook, clasped his hands together and showed a relieved smile: "Judging from the recorded data, there is no problem."

"That means we can set sail!"

Ace's eyes shone with excitement. He was no longer satisfied with just "driving" on the beach, let alone the fact that this meant they could finally escape the island and regain their freedom.

"I think we still need to test sail in shallow sea areas for a period of time."

Cos thought it was better to be cautious, so he suggested,

"After all, Ace is now a Devil Fruit user. It would be terrible if he accidentally falls into the sea while crossing the sea current. So it is better to officially set off now that Asami has completely mastered it. At least the two of us can still do it in Asami. Drag Ace ashore."

"Right."

Deus nodded in agreement.

"That means you can still sail on the sea, right?"

Ace heard the caution of Kos and Deus, and understood that he would no longer have to have sex on the beach, so his excitement still did not subside.

He patted the hull of the boat and said, "We haven't given it a name yet! Sure enough, it would be a bit uninspiring without a name. How about calling it STRIKER?"

"I'm still FREEDOM." (Strike in English is strike)

Kos responded casually.

"The Liberty is not bad either."

But Ace really started to compare the pros and cons of the two names.

"I think the Stormtrooper is better. After all, we need it to break through the currents that trap us here."

Deus voted for the Stormtrooper from the sidelines.

So, two to one, the boat was eventually named the Stormtrooper.

In the next few days, the three of them began to drive the Stormtrooper and began practicing in the shallow sea area. It turned out that Kos's worries were not unreasonable. During this period of practice, he and Deus pulled Ace out of the sea. Fetched it back ten times.

When the Charger could take an S-shaped route and sometimes a B-shaped route on the sea without any sign of capsizing, Kos and Deus finally thought it was time to set off.

The Stormtrooper was built with only speed in mind. There wasn't much space for carrying cargo on the streamlined hull. It was already a bit reluctant to just squeeze in three big men, so it could only be placed on the hull. Create a small storage room to store small amounts of fresh water.

"Even if we break through the current, if we are not rescued before the fresh water is exhausted, we will only die at sea."

Before setting off, Kos told the worst case scenario to inoculate the other two.

However, Ace and Deus did not waver in any way. They just boarded the Stormtrooper and asked Kos to get on the ship quickly.

"Yes, I would actually think of saying this to an idiot and someone infected by an idiot. It seems that I am also affected by them."

Kos smiled and shook his head and then boarded the Stormtrooper, but before he could sit firmly, Ace rushed out with a "fire" to prevent him from falling.

After that, the Charger rushed towards the sea without any further delay.

The weak undercurrent that initially teased the three of them had no impact at all on the powerful Charger;

The more rapid reverse current after that was not a huge nuisance;

Finally, there are the violent waves that continue to crush all those who escape.

Even though it was not the first time he faced it, Kos once again felt his insignificance in front of the huge wave that had the tendency to obscure the sky.

Deus was also slightly frightened in his eyes, but he had no intention of backing down and bravely faced the "enemy" who had driven him back twice.

"Hey! Thank you for taking care of me in the past few days."

As if reminiscing with an old friend, Ace greeted the waves that had knocked him into the sea countless times, and at the same time, his right hand and left hand burned with fierce flames.

The flames in his left hand poured into the Charger under his feet, further increasing its speed; the flames in his right hand continued to grow, and then rushed towards the waves with his fist.

"fire punch!"

With a loud shout, the cascading waves were briefly evaporated into a hole. From the hole, a small boat spraying flames flew straight out and returned to the free and boundless sea.
