"Impossible!!!" Yamamoto Isoroku roared madly, his figure swaying as he lunged at Lin Feng again.

However, after taking only two steps, he felt a powerful aura lock onto him, leaving him nowhere to hide and forcing him to stop.

"Yamamoto-kun, your swordsmanship is indeed impressive, but unfortunately, it's not authentic martial arts, so its power is limited. If you are willing to submit to me, I can take you as my disciple and teach you some martial arts to greatly increase your strength," Lin Feng said calmly.

Yamamoto Isoroku was greatly alarmed.

"You...you actually managed to see through my swordsmanship?!"

"When I was practicing martial arts, I met a master who taught me a sword technique called 'Flying Immortal from Beyond the Heavens.' This sword technique uses the sword as its main element, and the sword intent it unleashes is like a flying immortal from beyond the heavens, making it unpredictable and difficult to comprehend no matter how much I practice.

Later I learned that the ultimate essence of swordsmanship is not any particular martial skill, but rather the very nature of the sword.

"The reason I was able to see through the essence of the sword is because my fist technique and sword intent merged to create a new martial art called 'Tai Chi Seal.' I think you should be familiar with this fist technique, because that senior was a member of the Tai Chi Alliance."

"This Tai Chi Seal technique of mine is a closely guarded secret of the Tai Chi school. Now, I will pass this secret on to you."

"I hope you cherish this opportunity and don't let my efforts go to waste."

After saying this, Lin Feng closed his eyes and began to circulate his internal energy to regulate his body.

He had been holding back his power, not using his full strength, but only sealing his aura. Now he has completely broken the seal and restored his power.

Lin Feng's internal energy surged and roared, his momentum like a rainbow.

Yamamoto Isoroku stood frozen in place, his expression becoming incredibly complex.

"Tai Chi School..." he murmured to himself.

At that moment, a tremendous wave surged through his heart.

"I never imagined that he would create and pass down the martial arts of the Tai Chi School. How is that possible?!"

"No!! This is absolutely impossible. I must find out the truth, otherwise, this Tai Chi martial arts will definitely fall into someone else's hands, or even be stolen. I absolutely cannot stand by and watch all of this happen!!!"

Thinking of this, Yamamoto Isoroku's eyes darted around, a fierce greed flashing within them. He gritted his teeth: "Fine, I'll see just how strong this Lin Feng really is!!!"

With that, Yamamoto Isoroku stomped his feet on the ground and charged towards Lin Feng like a cannonball.

A sharp glint flashed in Lin Feng's eyes, and a cold smile curled at the corner of his lips: "Your speed, in my eyes, is still as slow as a snail."

"Yata no Kagami!!!"

Lin Feng flipped his wrist, and a silver-white mirror appeared in his palm.

With a "whoosh," the silver-white mirror flew out of her hand, hovering in mid-air, its surface shimmering with a faint golden light.

With a soft "hum", the light on the silver-white mirror surface rapidly spread, enveloping Lin Feng, and Lin Feng's figure disappeared.

However, the light from the silvery-white mirror still enveloped the surrounding area within a hundred feet, plunging the entire manor into darkness.

The next moment, Lin Feng appeared out of thin air behind Yamamoto Isoroku and threw a punch, using the same move as the punch he had thrown earlier.

Yamamoto Isoroku felt a strong gust of wind coming from behind him and quickly turned around, brandishing his long sword.

With a "whoosh," his slash missed its mark.

But he felt a tremendous force strike him, causing him to stagger backward and turn pale.

"What is this thing??" Yamamoto Isoroku was taken aback.

He had just turned around when another punch came flying at him.

With a "whoosh," the long sword in his hand was knocked away by Lin Feng's fist.

He was thrown several meters away by the force of the impact, crashing heavily to the ground. A large pool of blood gushed from his mouth, and his face instantly turned ashen.

"How terrifying! This guy is so powerful. I'm no match for him. I have to escape." Yamamoto Isoroku's expression was uncertain.

He thought for a moment, then darted into the nearby bushes and disappeared into the darkness.

Lin Feng stood still, squinting at the pitch-black night.

After a long silence, he sighed and slowly shook his head: "Never mind, he's already escaped. Whoever tried to kill my friend must pay the price. I have too many enemies now, and if I don't deal with them quickly, the trouble will only continue. The fact that Yamamoto Isoroku became Takeda Nobutaka's subordinate proves he's quite sensible."

Thinking it over, Lin Feng looked up at the mountaintop and stepped onto the summit.

At the top of the mountain, a young woman sat cross-legged on the ground. Her face was covered with a black cloth, so her features could not be seen, only her bright eyes were visible.

Hearing footsteps, she didn't turn around, but simply said indifferently, "You've come."

Lin Feng nodded: "Our agreement is over."

The woman in black veil slowly raised her head, looked at Lin Feng, and asked calmly, "Is it over?"

"Yes, it's over. Your strength is too weak. Even I didn't need to go all out to defeat you, let alone that Yamamoto Isoroku."

"You don't need to provoke me, I will not give up." The woman in black veil said, and with a clap of her hand, the void above the mountaintop distorted, and a mountain peak crashed down.

This mountain peak is tens of thousands of feet high, piercing the clouds, like a divine miracle.

Meanwhile, in the grass below the mountain peak, Yamamoto Isoroku was desperately trying to escape.

"Phew~~"

Yamamoto Isoroku's clothes billowed, his aura surged, and his speed increased considerably.

"This woman's martial arts skills are quite impressive."

"However, a martial artist like that couldn't possibly fight me."

His mind raced, and his figure moved like a ghost through the night, disappearing in no time.
