Of course, this sword formation consumes a lot of mana, and it even needs a strong soul power cultivation as a support, otherwise it will not be able to smoothly adjust the complex changes in the formation, and it is very likely that it will collapse on its own.

"Boy, don't be complacent!" the demon man said hatefully, and as soon as his words fell, he suddenly took out a black charcoal-like stone from the storage ring, which was the size of a baby's fist, and he stuffed it into his mouth and swallowed it raw.

As the stone entered his stomach, after only a short while, black light began to appear from all over his body, and the two sharp corners on his forehead began to lengthen, and lightning flashed.

Han Feng was slightly startled, he didn't think much about it, he held the broken sword tightly in his hand, but he held the sword trick in the other hand, the crystal light at the center of his eyebrows flickered, and the rolling soul power was released, and the two-pronged sword qi became more prosperous and shining brightly, forming a more terrifying sword light, surging with power, and constantly slashing the opponent.

It's a pity that this demon clan has been replenished at this time, and his strength has greatly improved, and a large black light flashes between his gestures, like a stormy wave, blocking the repeated attacks of the Sword Yuan Array.

What's even more peculiar is that patches of dazzling black scale armor began to appear on the surface of his body, and sometimes the sword qi hit his body, and these scale armor successfully resisted, only emitting brilliant firelight, but failed to break through his defenses.

"Sneer......"

Countless spatial cracks appeared, and dozens of sword lights as thick as buckets crossed and slashed towards this demon person, but they were all blocked by him.

But he tried to break out of the formation several times, but he was also suppressed back by Han Feng with the Five Elements Seal Ring, and after a long time of tea, he was still trapped in the sword formation.

"Let's see how long you can last!" Han Feng thought secretly in his heart, flipped his left hand, took out a top-grade spirit stone, and silently absorbed spiritual power to replenish the consumption in his body.

"You forced me!" After a fierce battle, the demon's breath shrank again, and after he said this coldly, while resisting attacks from all directions, he took out another black charcoal-like stone from the storage ring and swallowed it again.

After eating a piece, he ate another piece, and his strength rose again, far better than just now, that aura spread out, and even the sword qi in the sword array was shattered by it.

Seeing this, Han Feng didn't dare to delay any longer, and before he could completely refine the two black stones, his body moved, merged into the Sword Yuan Array, and used his body as a guide to mobilize the sword qi within a radius of dozens of miles, converging into a giant sword that reached the sky, and slashed at the other party.

The sword light burned like flames, burning in all directions, and a series of collapses occurred in the void, and the light of various colors scattered everywhere, setting off a long roar.

Feeling a life-and-death crisis, the demon man slapped his chest violently, opening his mouth and spitting out a cloud of dark blood.

The blood was like black charcoal, suspended in the air, dripping and swirling, and it emitted a scorching black light, thinking that it was his essence blood.

He urged the power of his whole body, so that this mouthful of essence blood quickly condensed into a magic seal, radiant and reflective of the entire heaven and earth!

The next moment, as he held the trick with both hands, the long knife in front of him shot up, touching this magic seal, blooming with dazzling brilliance, and a large sword phantom appeared in the air, colliding violently with Han Feng's Heavenly Giant Sword!

"Boom ......"

It was a loud sound that shook the sky, the space was like rippling water, and the colorful lines spread out to the surrounding areas, shaking the four fields.

The light was shining, the wind was howling, the sky was cracking, the sea was sinking, and huge whirlpools appeared below, humming and suctioning.

Those rays of light came fiercely and quickly, but when they dissipated, they also receded like a tide, and disappeared without a trace in a single breath, revealing the figures of Han Feng and the people of the demon race.

Both of their faces were as calm as water, and they didn't seem to be able to distinguish the winner from the loser, but Han Feng was still holding the broken sword, while the long knife of the demon clan was broken in two.

"Your sword......"

The people of the demon clan looked at Han Feng's broken sword and muttered, but before he finished speaking, his body suddenly cracked, and pieces of skin fell down like black charcoal, followed by flesh and blood, and then bones, completely falling apart, and then spontaneously combusting without fire and turning into a pile of ashes.

Han Feng looked a little strange, he was spreading his soul power to observe from beginning to end, but he didn't notice where the other party's True Pill was, which made him feel incredible.

"Could it be that the people of the demon clan don't follow the Qi Cultivation School, don't get the True Pill, and only cultivate the physical body?" Han Feng secretly guessed.

While thinking, he raised his hand to ingest the other party's storage ring, injected soul power and tried to refine it, but found that there was an inexplicable force blocking him, and he couldn't penetrate into it at all.

"This is a thing with a master!" Han Feng suddenly came to his senses, "It seems that this demon clan just now is just one of the clones!"

A doppelganger, it has such strength, much more powerful than the great monk who has completed the knot, almost comparable to a half-step psychic person, and the cultivation of its deity can be imagined, at least it is also the existence of a psychic person.

Speaking of which, this time he was able to kill the other party smoothly, on the one hand, he practiced the Sword Yuan Codex, which was able to make the power of the broken sword more pure, and on the other hand, the other party was a person from the demon race, in this secret world, there was a lot of discomfort, if it was in a place where the demon qi was abundant, it might not be so easy.

Han Feng couldn't help but feel a little more jealous of the so-called Alcatraz Island, that mysterious organization gave him too little information, and no one knew what kind of characters existed on that island.

He put away the storage ring, thought about it silently, and decided to rush to Alcatraz Island first, thinking that the Feather Immortal Sect would set up such a big game, and it would not just let his gang come to die.

After a short rest, he continued to fly southwest, and in a few flickeres, he disappeared into the sky.

......

After an hour or so, Han Feng went through the obstruction of many sea beasts, killed an unknown number of demon beast-level existences, and finally arrived at his destination, Alcatraz Island.

However, what made him feel strange was that in this short period of time, he hadn't met any of the demon people, and he didn't know if they had all gathered on this island.

Hundreds of miles away, he saw an island three or four hundred miles in diameter above the sea, the whole body was dark, and even the surrounding sea water seemed to be dyed black by something, like ink.

What's more, the sky above the island is also dark and dreary, and there are bursts of thunder and thunder, rumbling, shaking, and occasionally you can see a series of spatial cracks emerge, fleeting, and energy pouring out, sweeping in all directions.

Han Feng did not continue to fly forward, but hovered in mid-air.
