Under the dark red blood moon, the vast snowfield was in shambles, and large swaths of snow were turned up, leaking out the thousands of years of ice buried deep under the snow layer, and the upturned snow was piled up on the snow field in the east and west, turning the surrounding area into a hilly and undulating mountain.

In the midst of the heavy snowdrifts, two figures stood opposite each other. One of the tall red-robed men was panting, sweating profusely, and the clothes on his body had been cut several times by something, and they became leaky, and even there was an extra wound on his right face that was more than two inches long, and blood dripped down the wound, which made the big man even more hideous.

"Ling Tiannan, looking at your old and decrepit appearance, how can this Blood Demon Knife feel even faster than back then!" the Blood River Ancestor scolded and shouted, waving his hands to drive the blood water above to form a shield around him. Right now, most of his blood was cut and dispersed by the Blood Demon Knife that came and went without a trace, and the entire sea of blood was less than a quarter of the size of the original, and he only had the ability to defend, and he had no offensive power.

Ling Nanzi stood in the snow opposite, still looking indifferent, and with a wave of one hand, he commanded the Blood Demon Knife to fly in the air, and said lightly: "Let go of the obsession in your heart, no worries, and the knife will naturally be faster." River of Blood, your defeat has been presented, why bother to resist. ”

The red-robed man snorted and shouted: "Back then, Lao Tzu's life hung by a thread in the vast demon tide, and he never moved the idea of admitting defeat, so I didn't have the door to admit defeat!"

Ling Nanzi sighed lightly, his wrist flicked, and the red demon knife in mid-air trembled slightly as if he had suddenly received an order, and turned around like lightning and headed straight towards the Blood River Ancestor!

Although there was still a shield composed of blood and water around the Blood River Ancestor, it was already less than a foot thick under repeated weakening, and in the blink of an eye, it was blown all over by the wind around the Blood Demon Knife, and it was completely unable to stop the momentum of the Demon Knife, only to see a red line flashing, and the Blood Demon Knife had reached the front of the Blood River Ancestor!

Seeing that the blood knife had come to him like a ghost, the Blood River Ancestor's face sank, a trace of fierceness flashed in his eyes, he shouted, pulled out a sword from his waist, and slashed it at the Blood Demon Knife!

Thunder roared, like spring thunder, rolling and spreading out on this snowfield! A blood-red sword light that was three or four zhang wide erupted from where the Blood River Ancestor was standing, shooting straight into the distance along the snowfield like lightning!

The earth could not withstand the tremendous force that destroyed the world, and shook violently, and after a while, the shocking sword light dispersed, leaving a deep ravine three zhang wide on the snow field, stretching straight into the distance, and there was no end in sight!

Ling Nanzi stood less than a foot on the side of the ravine, looking at the Blood River Ancestor, his brows furrowed slightly. Beside him, the strange blood knife had quietly returned, quietly suspended in mid-air, motionless, meekly guarding his master's side.

"Seven Killing Sword...... Where did you get this fierce sword?" Ling Nanzi asked with a frown, originally this trip to capture the Blood River was a sure thing, but I didn't expect that this Blood River had such a divine weapon in his hand, and it suddenly added a lot of variables!

At this moment, the Blood River Ancestor was standing on top of the snowfield, holding a blood-colored long sword in his hand, and the sword body was surrounded by a light red mist, and it was impossible to see the true face of the sword, and the mist around the sword body was regularly retracted and contracted, as if a human heart was beating!

Blood River Ancestor's face was a little pale at the moment, it seemed that the earth-shattering sword before was not a light move, he laughed a few times, and said: "You don't care where I got it! Is it only allowed for you to have a demon sword, not for Lao Tzu to have a divine sword, now that I have the Seven Killing Sword in my hand, you may not be able to help me!"

Ling Nanzi shook his head slightly, and said, "Break the army and protect your life, and kill the master seven times." With such a fierce sword, I'm afraid that your future will be worrying!"

The Blood River Ancestor snorted and shouted: "Lao Tzu's life is harder than the iceberg in this extreme north, what can a mere sword do to me! Don't talk nonsense, the Seven Killing Sword has come out, and I won't die today!"

Ling Nanzi sighed, still standing in place, the blood knife on his side trembled, and flew towards the Blood River Ancestor in the air like lightning......

Beneath the vast snowfield is tens of thousands of years of ice, which is harder than rock, and crisscrosses each other underneath, stretching out layer by layer.

Beneath the thick layers of ice, there is a world of crystal clear ice. Dozens of thick icicles rise from the ground, supporting the entire ice vault, forming a natural ice palace, this hall is dozens of zhang wide, the ground is smooth as a mirror of the huge ice surface, in the cracks of these ice surfaces, there is a cold river gurgling flowing.

The surrounding icicles are embedded with large and small night pearls, emitting a faint brilliance, illuminating the entire ice palace as bright as day. The surrounding scenery is unobstructed, in this underground palace, there is only endless ice as far as the eye can see, and there is no trace of air flowing, as if it has been frozen by the cold of this underground ice palace.

In the cold world of ice, in the center of the mirror-like hall floor, past a few thick icicles, you can see a long-haired girl, sitting quietly on the ice, holding a book in her hand, reading intently there.

This girl looks like she is only seven or eight years old, wearing only a set of coarse cloth clothes, and her hands and feet are **** outside. Her face was as white as snow on the snowfield, there was no trace of blood, and her hands and feet were as white as paper, and she looked particularly strange against the backdrop of her long black hair.

The severe cold in this underground palace is unbearable even for monks who have a good way. But this girl, dressed in a single dress, sat on the ice wall and read as if nothing happened, which is really weird.

The girl held the scroll in her hand, and looked very attentively, her body did not move for a long time, and her complexion was pale, like an ice sculpture in this ice palace.

Suddenly, a dull loud bang came from above, and the vault above the head shook, and some fine ice chips fell one after another, drawing a crystal light in the air.

The girl frowned slightly, and looked up, she had lived in this ice palace for a long time, and she had long been accustomed to the quiet environment that was silent all day long. But today, I don't know what's going on, the loud noises above are one after another, and it's impossible to calm down and read a book.

The girl sighed, gently closed the scroll in her hand, put it aside, stood up and said to herself: "I have also read this "Tao Theory" several times, and the way of formation change in it has been memorized. I'll have to read these books all over again in the future. ”

Not far from the girl's side, there are piles of various books on the ground, piled up like a hill, the girl lives in this underground ice palace all the year round, there is nothing around, only to pass guò to read books to kill time, over the years, the number of books read is already amazing.
