Hearing this, Han Zheng smiled slightly, held his black beard, turned his head to meet Lin Feng's gaze, and explained seriously: "The ten-shaped square seal array is one of the strongest soul techniques in the soul world, it contains many mysteries, and it is full of savage atmosphere, according to historical records, among the ten-shaped square seal array, the one-shaped square seal array is the most difficult to crack, and it is also the most dangerous!"

After listening to Han Zheng's general explanation, Lin Feng didn't seem to understand, he didn't know much about the concept of the ten-shaped square seal array, and he was confused, and turned his head to look at the one-shaped square seal array among them.

At the same time, the masked man standing in the magma cave, the cold ice ball in his palm had been completely formed, spreading a savage aura, enthusiastically rolling in his hands, exuding a thick and fierce energy, with the speed of an arrow, towards the hot magma on the wall, smashing hard.

A majestic breath energy, at lightning speed, rolled out from within it, like a wave-like cold air, wave after wave, fan-shaped ripples, abruptly spread to the surrounding walls, in an instant, the entire magma cave shook and shook, spider web-like cracks, from the midpoint to the surrounding areas, hot magma dripping on the ground from time to time.

"How is this possible, the power of the ice ball is extremely great, how to use it in the magma cave, the strength is actually offset by more than half!"

The masked man's face changed slightly, his dark eyes flashed with horror, and he muttered to himself, turning his head to look at the surrounding magma walls, only to see that the ice cubes frozen on the walls were instantly melted away by the hot magma, and the cracks that spread out, as if some kind of gravitational force coincided, slowly inlaid together.

"Haha...... With your strength alone, you are far from being able to crack the one-shaped square seal array, I advise you to save some effort!"

Just when the masked man was frightened, a low voice quietly resounded in the magma cave, hearing this, the masked man snorted coldly, a sharp look flashed in his eyes, and shouted hideously: "Hmph! Hydra, I advise you not to be happy too early, as long as I break a square seal array, the rest will not be a problem, and it will be up to you what you say." ”

The voice landed, slowly closed his eyes, faintly moved his strong spiritual power, a black light swept out between his eyebrows, flashing a black dot like a soul pill, a loud shout, a crazy streamer, burst out, the breath of antiquity spread out, oozing out of the magma cave, and the voice shouted: "Red Dragon, you hurry up and work with me to break a square seal array!"

It lasted for a moment, a sky-breaking dragon roared, like a chain of powerful sound waves, burst out from the mouth, showing a ripple-like huge wave, suddenly to the surrounding frozen holes, fiercely pounced on the past, a low explosion sounded, instantly sounded, the ice embedded in a piece, burst, the strong broken ice fan-shaped, with a sharp sound of breaking wind, shattering the surrounding void, swept out to the surroundings.

"Click!"

A low cracking sound quietly sounded in the ice cave, like a huge spider web-like crack, showing ripple-like traces, spreading from the midpoint to all sides, a huge red dragon, with a bloody mouth, its body shrouded in ice embedded in a piece, it appeared crystal clear, with the speed of an arrow, instantly swept away, faintly only saw a vague dragon shadow, the strength of which was amazing.

"Whew!"

In the huge magma cave, the hot magma, like a huge fireball, rolled up wildly all around, rushing towards the masked man, facing the blazing fireball, the entire void fell into a high temperature, if it were not for the soul with super strength, it would definitely be melted by this high temperature, this must be undoubted.

"Hey...... The red dragon is coming, Hydra, I think you have to obey me!"

An evil laugh suddenly resounded in the magma cave, seeping out of the thick magma wall, bursting out of the void, the whole sky also resounded with a familiar sound, the masked man settled down, looked around at the fireballs rushing around, stomped on the soles of his feet, the whole body was like a phantom, rushed to the top of the magma cave, turned around suddenly, stunned for a moment, I didn't expect the speed of the fireball to be so fast, the sleeve robe shook suddenly, and the strong vitality in it rushed out, turning into a sharp inch blade, in a fan-shaped direction, suddenly to the surrounding fireballs, penetrating away。

"Boom!"

The sharp blade will be a fireball, from the middle of the crazy cut, a deafening explosion, burst out, burst out of the magma, in the direction of the arc, poured out to the surroundings, a cloud of magma like blood mist, at the same time, violently exploded, the entire magma cave is filled with dense magma, the magma on its wall, as if by some kind of stimulation, instantly boiled, from time to time burst out of violent fireworks, the space is located, the temperature rises violently, the air ripples like waves, it is extremely difficult to breathe。

A phantom shadow slowly fell on the ground, surging on the magma, wisps of black mist appeared in an instant, sneered, turned his head to look around the wall, the hot magma stuck to the wall, from time to time there were small bubbles, buzzing and non-stop, but the small bubbles that came out, like an atomic bomb, showed an arc shape, and the magma surging around it, turned into the essence of the gas, melted in it, making the small bubbles, instantly reach a saturated state, burst out from the wall, and burst towards the masked man.

"This ...... The magma cave is so weird, it seems that I underestimated a square seal array!"

His expression didn't change much, his brows furrowed slightly, a touch of horror flashed in his eyes, and he muttered to himself, the blisters that burst out from the wall were extremely fast, and his body exuded a fierce aura, as if he was going to explode the entire magma cave.

"Hmph, it seems that the old man has to use the strongest soul technique!"

The soles of his feet stomped hard, the magma bubbling on the ground, rippled out of the rippled gas, the light body flashed, standing steadily in the middle of its magma cave, sharp like an eagle's eye, looking around at the blisters, a loud shout, both hands raised, a giant tiger like a phantom, broke out, a tearing tiger moan, whistling out from the mouth, faintly powerful sound waves, like a blood-red phantom, towards the direction of the fan, burst out.

"Bang!"

The water bubbles that spread in its magma cave, as if encountering natural enemies, exploded in an instant, like blood-red magma, overflowing and bursting, pouring out in all directions, in its mid-air, quietly exploding magma like mushroom clouds, by the violent force of the burst, the overflowing magma stuck to the wall, and then slowly seeped out, forming a stronger blister than before, which was permeated with hot magma.

"It's never finished, it turns out that the blisters are born in cycles, which ...... It's terrifying!"

Standing steadily in mid-air, he turned his head to look at the blisters on the wall, and in his dark eyes, there was a touch of horror, and he couldn't help but be surprised, he originally thought that the one-shaped square seal array could be cracked as long as he cast a little soul technique, but he really didn't expect it to be so difficult, and he had underestimated the ten-shaped square seal array before.

"Haha...... I said a long time ago that with your strength, you are far from being able to break the one-shaped square seal array, not to mention that there are nine formations behind, but after going through seven hundred and forty-nine tribulations, you can only crack it!"
