On the surface, this ability seemed very simple. The entire process was to first consume a large amount of food, then use elementalization to turn both the food and the body into an element, before turning back into a normal body.
After repeating this a certain number of times, the body would store a huge amount of energy. Then, through regular training in the Sea Cloud Gravity Room, the body could completely adapt to the powerful energy within it.
It was actually somewhat similar to the ability of a Senzu Bean.
This adaptation process was also the process through which the body became stronger.
The effects of this training were obvious. By now, Ye Mu's physical strength and power had been increasing rapidly at a steady rate.
With Ye Mu's help, Enel soon developed the same ability.
Now, Ye Mu had just turned eleven. After three years of development, he could lift a massive boulder weighing ten tons. Enel had missed out on those three years, so his strength and physical body were somewhat inferior, with his limit being around four tons.
However, Enel had developed his Devil Fruit ability to an unbelievable degree. At only eleven, he had already awakened Mantra, which was the ability known as Observation Haki. Although its range was nowhere near as frightening as it was in the story, it was already something to be proud of.
One had to know that even Ye Mu still had not touched the threshold of Haki.
It was precisely because of this that although there was a considerable gap between them in terms of strength, Enel could still fight Ye Mu back and forth with the help of Observation Haki.
However, for exactly that reason, the two of them had to eat several times their body weight in food every day for their training.
Ye Mu was decent at preparing simple dishes, but when it came to handling prey several times larger than their bodies, he was still somewhat overwhelmed. As a result, the taste was only average.
This also made Ye Mu realize how important a chef was.
Fortunately, besides meat, there was also fruit. With both meat and vegetables, they could not only obtain abundant nutrition but also ease the greasiness.
Apples, for example, were Enel's favorite.
Unlike meat, which Ye Mu could hunt and prepare anywhere in the Upper Yard, fruit was most conveniently purchased from the various Sky Islands.
Because the two of them consumed so much food, Ye Mu had to visit different islands every week to buy fruit.
For example, right now, after Enel wolfed down the last apple, the box was already completely empty.
"All right, I understand. I'll go tomorrow morning..."
After saying this, Ye Mu went to rest.
Training had already left his body exhausted. Under such circumstances, he absolutely could not overlook the importance of rest.
As soon as dawn broke, five years of regular training had already turned the two of them into creatures of habit.
Without anyone saying a word, Enel began his own training.
Ye Mu transformed into a flame, flew into the sky, and arrived at the edge of Angel Island.
Without even greeting Pagaya, Ye Mu dragged a Waver away from his doorstep, climbed aboard it, and followed the rising sea of clouds toward Angel Island.
Before that, however, he still had to make some preparations.
Although Ye Mu was not afraid of others discovering his identity, he did not want to cause trouble right now. Thus, he took out the fake wings he had prepared long ago and put them on.
Ye Mu had come to Angel Island so many times that he knew the place like the back of his hand. Even the shopkeepers were nearly familiar with him.
After all, there were not many big spenders like Ye Mu.
As for where the money came from, he had to thank Gan Fall. Whenever Ye Mu ran out of money, he would make a trip to the treasury of Gan Fall, the god of this Sky Island.
The first thing he needed to buy was the apples Enel loved most. Ever since Ye Mu had bought Enel apples on Angel Island once, Enel had become obsessed with them and could eat more than half a box in a day. Even now, Ye Mu found it frightening whenever he thought about it.
However, when Ye Mu arrived at Angel Island's market, he discovered that there seemed to be fewer people than usual today.
He asked the owner of the fruit shop, somewhat puzzled.
"Why are there so few people today...?"
The fruit shop owner was not particularly surprised. He casually replied,
"Today is the annual rising of the massive ocean current. Everyone has gone to attend the ceremony."
"I see."
Over these five years of living in the Sky Islands, Ye Mu had discovered that, unlike the people of the Blue Sea, whose understanding of the Knock Up Stream in the story was rather superficial, the people of the Sky Islands seemed to know in great detail when the Knock Up Stream would appear and how powerful it would be. They even had a special calendar recording such information and held a celebration for it every year.
And Ye Mu had descended to the Sky Islands on this very day five years ago.
"Five years already..."
Ye Mu sighed with some emotion. Going by his age, he was probably eleven now.
Just then, Angel Island suddenly began to shake violently, and all its residents instantly panicked.
"It really is a sight seen only once in a century. I can't believe the current is this huge..."
The fruit shop owner beside Ye Mu let out a strange exclamation. Ye Mu followed his gaze and was left somewhat stunned. A colossal torrent of water erupted like a spear piercing the heavens, rising from the horizon. Its height was actually comparable to the enormous, towering green vine in the Upper Yard.
"My goodness..."
Those who had not witnessed it with their own eyes truly could not understand how magnificent the sight was.
Before that gigantic current, every person was as tiny as a speck of dust, while the entire Angel Island was merely a slightly larger ant.
Ye Mu even suspected that not even Aokiji at his peak would be able to freeze this enormous current.
Faced with the power of nature, Ye Mu felt a trace of fear in his heart.
Just as Ye Mu was marveling at the sight, strange words suddenly sounded beside his ear.
"Eh... What's that!?"
Ye Mu turned his head and saw an extremely burly man holding a telescope and staring at the Knock Up Stream. The man seemed to have noticed something strange and cried out in surprise.
Ye Mu looked in the direction the man was watching. He could indeed see a tiny red dot, but it was so small that he could not make out what it was at all.
Curious, Ye Mu asked the burly man,
"Hello, could I borrow that to take a look?"
The burly man courteously handed him the telescope. Ye Mu raised it, aimed it at the red dot, and looked carefully.
At first, Ye Mu had not paid much attention and was merely curious. But the instant he saw clearly what the red dot was, his eyes widened in shock.
That pirate ship, that flag, and that man...
Unable to control himself, Ye Mu murmured a name.
"Gol D. Roger..."
After saying this, he returned the telescope to the burly man, boarded the Waver, and hurried toward Shandora...
