Eastern Sea territory.

On a small island approximately a hundred miles away from land, the rising sun flag of Japan now stands unfurled in the wind, with a bustling crowd of martial artists covering the island.

Everything is organized, proceeding with formations and drills...

There are also martial artists dressed in peculiar outfits, each seeking the mountain peaks to refine the Heaven and Earth Primordial Energy.

Although due to Martial Emperor City's influence, the overseas Japanese powers haven't landed yet, surrounding sea territories have essentially been occupied.

Named and surnamed islands have also been seized.

This... is just one of them.

By the seashore, two figures stand against the wind, facing the sea, steadfast and upright. One of them is dressed in a Black Robe, with a youthful appearance and a clean face.

He is none other than the Japanese Immortal Chen Yuan encountered on Divine Dragon Island after Crossing Tribulation, Yagyu Toshi, the ancestor of the Yagyu Family.

He is now also the leader of the three major families in Japan, and the campaign to attack the Central Plains with almost full force was orchestrated and strategized by him.

As for the person beside him, clad in a purple robe with mysterious patterns, his cheeks sunken and extremely emaciated, resembling the Hall Master of Seven Killings Hall.

His entire body is stiff, with only his faintly lingering gaze marked by Spirit.

He is named Muto Shenjing, the foremost powerhouse of Japan three hundred years ago, whose prestige once overshadowed the three families, aspiring to establish a family of equal stature.

However, unexpectedly, Muto Shenjing vanished completely after claiming the title of Japan's strongest, with some saying he failed to break through the Six Realms and fell.

Others say he broke through the Six Realms long ago and roamed the seas.

Yet others claim he had some interest in the Central Plains Immortal Sect, challenged it but was killed by an Immortal from there, leaving many legends about him.

And he also left behind a title.

Blood Sea Sword God!

Yes, in Japan, where the way of the blade flourishes, he wielded a sword... with the sword, he garnered the name of Japan's foremost genius, truly a prodigious talent.

"I thought you wouldn't come."

The youthful-looking Yagyu Toshi, though his voice was rather aged, making it quite eerie.

Long ago, Yagyu Toshi suspected another Immortal existed in Japan, though they had remained hidden and tracing them yielded no sign.

But he knew Muto Shenjing was likely still alive, personally visiting the Wuteng Family, yet returning without any worthwhile result, thwarted in his hope and left to battle the Central Plains on his own.

Unexpectedly today... he did come.

Truly surprising.

Muto Shenjing gazed into the boundless sea and said faintly:

"I came to repay the guidance given by a predecessor in the past."

Three hundred years ago, Yagyu Toshi had long broken through the Six Realms with extraordinary strength. When Muto Shenjing sought instruction, he was not discouraged but rather received key pointers on breakthrough.

This kindness must be repaid.

"The second reason is for the preservation of Japan. As a Japan Martial Artist, in times of crisis, action is needed."

The main reason compelling Muto Shenjing to take the risk to come to the Central Plains is the impending great calamity for Japan, now spreading among the various powers in Japan.

Thus, Yagyu Toshi gathered so many martial artists to unite.

Only, what still puzzled him was the nature of this great calamity.

He had asked some who could glimpse heavenly secrets, but the foretold calamities varied. Some said a land of fire would erupt, burning Japan to ashes.

Some foresaw the sea would churn, engulfing the land and burying Japan.

Others predicted increasingly scarce Heaven and Earth Primordial Energy, leaving no martial artists thereafter.

Though he sought answers, he found nothing.

"I wasn't wrong about you."

Yagyu Toshi nodded in satisfaction.

"Now, do you know what the great calamity is, so Shenjing can prepare?" Muto Shenjing shifted his tone to inquire about this long-standing curiosity.

"The great calamity..."

Yagyu Toshi's gaze grew profound, his brows furrowed, after a long silence, he confessed:

"In truth... I am not entirely certain, but one thing is sure, the great calamity is real, and this region's calamity will sweep across Japan's four islands.

If we don't prepare early, our land will completely dissolve...."

"So, establishing a foothold in the Central Plains is essential?"

"That's correct, throughout history, the Central Divine Continent has been the center of it all. Rich in resources, drawing powers from all sides to compete for it, such a blessed land should have Japan a place in it.

I do not seek to occupy all of the Central Plains, but only hope for a refuge for my people of Japan, sadly... people of the Central Plains are narrow-minded, viewing us as enemies."

"There's an ancient saying in the Central Plains: 'Those not of our kind, their hearts must be different,' which means without resorting to force, it's difficult to establish a foothold in the Central Plains."

Muto Shenjing spoke solemnly.

"Indeed, be it Martial Emperor City or King Yan Chen Yuan, even the soon-to-be-extinct Sima Family of Great Jin, they view Japan as barbarians, never giving us a proper regard.

There's a grievance in my heart, if the day comes when we break through the Central Plains, we must enslave the Central Plains Martial Artists, so they may never rise again."

Yagyu Toshi's eyes grew dark, filled with murder.

"What of the Buddhist sect? Northern Barbarians? Southern Border demons? As I know, the Central Plains is surrounded by enemies, if all forces move together, the Central Plains will be divided."

Muto Shenjing was not oblivious to worldly affairs during his slumber; he once ventured alone to the Central Plains and visited Western Regions, Grassland... aware they too have long coveted the Central Plains.
