Teaching and Resonance

Early the next morning, Lin Feng and Ace arrived on the deck bright and early.

"Ace, are you ready?" Lin Feng asked.

"Of course!" Ace said eagerly. "Let's get started!"

"Alright, I'll first demonstrate Sun Breathing for you," Lin Feng said. "Watch closely!"

Lin Feng took a deep breath and activated Sun Breathing: Full Concentration.

"Breathe... in..."

Lin Feng's breathing became long and slow, each breath seeming to harmonize with heaven and earth. The air around him began to distort, and an invisible wave of pressure spread outward from his body.

"So this is Sun Breathing? It really is incredible!" Ace felt the powerful aura emanating from Lin Feng, his eyes full of amazement.

"This is only the most basic Full Concentration Breathing. Next, I'll teach you the forms of Sun Breathing," Lin Feng said.

Sun Breathing: First Form: Dance!

Frost Gale in Lin Feng's hand flashed with a dazzling blade light as it slashed toward Ace.

"Bring it on!" Ace neither dodged nor retreated, throwing a punch. "Flame Fist!"

Boom!

The blade collided with the flaming fist in an ear-splitting crash. The powerful shockwave sent the surrounding pirates staggering in every direction.

So strong! Ace felt the power behind Lin Feng's strike and was secretly shocked.

"Again!" Lin Feng roared, swinging Frost Gale once more.

Sun Breathing: Second Form: Clear Blue Sky!

Sun Breathing: Third Form: Blazing Red Mirror!

Sun Breathing, Fourth Form: Fake Rainbow!

In one breath, Lin Feng demonstrated every form of Sun Breathing, leaving Ace dazzled and unable to take it all in.

"Well, Ace? Did you see it clearly?" Lin Feng asked.

"Mm... more or less," Ace said. "But I'll need to practice it a few more times."

"Alright, then I'll practice with you!" Lin Feng said.

"Nothing could be better!" Ace said excitedly.

Over the next few days, Lin Feng and Ace practiced Sun Breathing on the deck every day. Their sparring also drew crowds of pirates to watch.

"Captain Lin Feng and Captain Ace's fights are incredible!"

"Yeah, those two are both monsters!"

"Who do you think is stronger?"

"That's hard to say, but I think Captain Lin Feng has the edge!"

"I think Captain Ace is stronger. His Flame-Flame Fruit power is just too overwhelming!"

The pirates discussed it animatedly, all acknowledging Lin Feng and Ace's strength.

"Ace, you've more or less mastered Sun Breathing. Next, it depends on whether you can combine it with your Flame-Flame Fruit power," Lin Feng said.

"Mm, I'll work hard!" Ace said.

"I believe in you!" Lin Feng patted Ace on the shoulder. "By the way, Ace, can you let me experience your Flame-Flame Fruit power?"

"Of course!" Ace said, stretching out his right hand. A ball of flame rose from his palm.

Lin Feng reached toward the flame and felt a searing heat.

"Hot!" Lin Feng said.

"Haha, it's Flame-Flame Fruit fire, of course it's hot!" Ace said with a laugh.

"Ace, what do you think would happen if you infused Sun Breathing into your flames?" Lin Feng suddenly asked.

"Infuse it into my flames?" Ace froze. "Would that work?"

"You won't know until you try!" Lin Feng said. "Come on, raise the temperature of your flames to the limit, then try infusing Sun Breathing into them!"

"Alright, I'll try!" Ace said.

Ace closed his eyes and began trying to infuse Sun Breathing into his flames.

"Breathe... in... breathe... in..."

Ace's breathing became long and slow. The flames in his palm also began to change, their color becoming deeper and their temperature even more intense.

"This... this is..." Ace felt the change in the flames, his eyes full of shock.

"It worked! Ace, you did it!" Lin Feng said excitedly.

"I feel like my flames have become stronger!" Ace said.

"That's right. This is the effect of Sun Breathing resonating with the Flame-Flame Fruit power!" Lin Feng said. "Ace, you really are a genius!"

"Haha, it's all thanks to you!" Ace said with a laugh.

"We're brothers. Why are you talking about who deserves credit?" Lin Feng said.

"That's right, we're brothers!" Ace nodded heavily.

"Ace, try again. Infuse Sun Breathing into your techniques!" Lin Feng said.

"Alright!" Ace said as he began trying to fuse Sun Breathing into his own technique.

Flame Fist!

Ace threw a punch. A layer of golden radiance wrapped around his fist, and the flames' power was several times greater than before.

"This... this is..." Ace stared at his fist, his eyes full of disbelief.

"Wonderful! Ace, you succeeded!" Lin Feng said excitedly. "Your Flame Fist can now be called the Sun Flame Fist!"

"Sun Flame Fist..." Ace murmured. "Good name!"

"Ace, you're incredible!" Lin Feng praised. "Your current strength probably isn't inferior to Marco's anymore!"

"Haha, it's all thanks to Big Brother!" Ace said with a laugh.

"Good brother, no need for formalities between us!" Lin Feng said. "By the way, Ace, can your Great Flame Commandment: Flame Emperor be combined with Sun Breathing?"

"I'll try!" Ace said.

Ace took a deep breath and pushed Sun Breathing to its limit. Then he raised both hands high as the flames around his body surged wildly, forming a massive fireball above his head.

Great Flame Commandment: Flame Emperor!

Ace roared and hurled the fireball in his hands toward Lin Feng.

"Bring it on!" Lin Feng roared. "Armament Haki: Hardening!"

Lin Feng pushed his Armament Haki to its limit, covering his entire body before throwing a punch.

Boom!

The fist collided with the fireball in an ear-splitting explosion. The powerful shockwave sent the surrounding pirates staggering in every direction.

"Cough, cough..." Lin Feng was blasted backward by the immense force, a trace of blood spilling from the corner of his mouth.

"Big Brother, are you alright?" Ace hurriedly asked.

"I'm fine!" Lin Feng wiped the blood from his mouth. "Ace, your Flame Emperor's power has increased quite a bit!"

"Hehe, it's all thanks to Sun Breathing!" Ace said with a smile. "Big Brother, you're amazing. You actually created such a powerful breathing style!"

"Hehe!" Lin Feng merely smiled without saying anything.

"Ace, let's keep training!" Lin Feng said.

"Alright!" Ace nodded.

In the days that followed, Lin Feng and Ace trained together every day, and both of their strengths rapidly improved.

"Captain Lin Feng and Captain Ace are getting stronger and stronger!"

"Yeah, those two are practically monsters!"

"Do you think the two of them will surpass Pops someday?"

"Th-that's hard to say, but I believe they'll definitely make a name for themselves on these seas!"

The pirates discussed it animatedly, all filled with anticipation for Lin Feng and Ace's future.
