The nine-headed demon snake suddenly lost one head, and the remaining eight heads stared at the Purgatory Demon, their amber eyes full of anger, but in the next second, the severed head grew again, and then the nine large mouths suddenly spat out gray beams of light.

Even if he was attacked by a third-order forbidden technique, his combat power did not decrease in the slightest.

Shi Feng didn't dare to be careless, and hurriedly controlled the Purgatory Demon to dodge away.

Everywhere the gray beam passed, it turned into a gray stone.

However, with a full nine gray beams of light, Shi Feng couldn't control the Purgatory Demon like his own body, and accidentally hit a gray beam.

In an instant, the Purgatory Demon lost more than 500,000 HP, and there was an additional petrification state on his body, losing more than 200,000 HP every 2 seconds, and his movement speed decreased by 60% for 30 seconds.

"This petrification skill is too strong!" Seeing the petrified state, Shi Feng hurriedly used the Life Ring of the Water Ring to bloom on the Purgatory Demon.

In the petrified state, not to mention the loss of health, just being caught up by the Hydra Demon Snake will be finished in less than 30 seconds for the Purgatory Demon.

With the health bloom, the health of the Infernal Demon is restored at a terrifying rate.

Recover 60% of the health per second, with the total amount of 13 million Purgatory Demons, even if the Hydra Demon Snake is powerful, it is impossible to kill the Purgatory Demon in seconds, and the Purgatory Demon is equivalent to having an immortal body within 40 seconds.

Immediately, Shi Feng used the Purgatory Demon Demon to lure the Nine-Headed Demon Snake open the huge stone gate.

When the Hydra Demon Serpent was 40 yards away and his attention was all on the Purgatory Demon's body, Shi Feng immediately turned on the Wind Walking Step and rushed towards the stone gate.

The clock ticked by. The distance from the huge stone gate is getting closer and closer, and Shi Feng is also beating a drum in his heart.

If discovered by the Hydra. That's the end of it, with the Infernal Demons. At most, it is not dead, and it is impossible to stop the nine-headed demon snake.

It took Shi Feng more than 6 seconds to rush all the way to the huge stone gate, and the Purgatory Demon also lured the Hydra 100 yards away and began to entangle desperately.

The Purgatory Demon was simply a toy in front of the Hydra Demon Snake, and he was bombarded to the ground again and again, with hundreds of thousands of injuries on his head one after another, and he had no power to fight back at all.

Shi Feng also immediately put the elemental core into the stone hole of the huge stone gate.

Suddenly, the magic array on the elemental core coincided with the magic array in the stone hole, blooming with a faint golden light. Immediately after that, the entire stone gate lit up with golden divine scripts, and the chains on the stone door began to disintegrate one by one.

"Quick!"

"Hurry up!"

Shi Feng looked at the chains on the stone door that began to break, and his heart was extremely anxious.

There are more than twenty chains on the stone door, and one disintegrates in a second, and it takes at least twenty seconds to fully open the stone door.

As the chains disintegrated one by one, the originally weak divine power became stronger and stronger.

"Not good!"

Shi Feng's face was slightly gloomy, and he turned his head to look at the nine-headed demon snake who was teasing the Purgatory Demon, his divine power was constantly increasing, and even he could feel it. Not to mention the Guardian Beast Nine-Headed Demon Snake.

At this time, the nine-headed demon snake really sensed that Shenwei was getting stronger, and couldn't help but look at the stone gate, and suddenly the snake's tail flicked, and it flew away from the purgatory demon. Turned around and rushed towards Shi Feng.

And there were still ten chains left on the stone gate, and with the speed of the nine-headed demon snake, it didn't take that much time at all, and he could easily rush to Shi Feng and kill Shi Feng.

Shi Feng had no choice. Immediately control the Cursed Demon and attack the Hydra with a third-order skill, the Spirit Blade.

The Psychic Blade is not just a magical attack skill, but also causes the target to fall into a state of confusion. Lasts 15 seconds to buy him enough time.

The nine-headed demon snake was also anxious this time because the stone door was opened. did not resist the attack of the spirit blade, and directly received more than 300,000 points of damage, and the huge body suddenly stopped, let out a miserable scream, and his eyes became a little confused.

"Great." Shi Feng couldn't help but breathe a sigh of relief.

Although the magic resistance of the nine-headed demon snake is not low, it is only a great lord after all, and the effect of the third-order skill on the nine-headed demon snake should be good.

As the chains broke one by one, the eyes of the nine-headed demon snake gradually became clear and translucent.

Seeing that the last three thickest chains were still not broken, the Hydra Demon Serpent was fully awake and let out an earth-shattering roar, its amber cold eyes suddenly turned blood-red, and its big mouth opened up, spitting out a gray beam of light again.

There were nine gray beams, each of which was enough to kill Shi Feng in an instant, and the nine gray beams completely blocked Shi Feng, and there was no way to avoid it.

Shi Feng immediately used the replacement skill.

The replaced clone directly lost its health to zero, turned into a gray fossil, and then shattered into dust and dissipated with the wind, without even the slightest power to resist.

Seeing Shi Feng disappear completely, the Hydra Demon Serpent turned its target to the cursed demon not far away.

Seeing this, Shi Feng immediately let the cursed demon flee for his life.

The speed of the cursed demon was too slow for the nine-headed demon snake, and it was caught up before it ran a few steps, and as soon as the snake's tail twitched, the cursed demon was imprinted in the rock wall, and the health of more than nine million immediately dropped more than 400,000.

In less than 3 seconds, the cursed demon lost more than two million health.

"Good opportunity." Shi Feng found that the chains of the stone gate had been completely untied, and immediately used the spatial movement of the empty ring, and came to the stone gate again, reaching into the stone hole with one hand and twisting the elemental core.

The elemental core clicked, and the huge stone door began to slowly open.

The nine heads of the nine-headed demon snake turned, and they were stunned for a moment, but they didn't expect Shi Feng to appear again, maybe they felt that the last time the skill was not strong enough, this time the nine heads of the nine-headed demon snake opened their big mouths again, but this time they didn't spit out a gray beam.

It was just that a huge triple magic array appeared over the entire stone gate, the whole sky was dark, a black wind blew, and the huge magic array shrouded a radius of 300 yards, and even the Purgatory Demon and the Cursed Demon in the distance were attacking the range.

Shi Feng's originally excited expression suddenly became solemn.

The magic used by the Hydra Demon Serpent has been seen by Shi Feng.

The third-order forbidden spell Dark Torrent is a super-large destruction magic that can last for 10 seconds, and under this magic, he has no skills to resist.

The Ring of Emptiness of the Ring of Seven Dawn is still on cooldown, and it is impossible to exchange the Ring of Earth or the Ring of Illusion, and with the number of times Edgeworth returns to the sky, it can't stop the torrent of darkness at all.

A black wind swept in from the sky.

Shi Feng can only use a dead horse as a live horse doctor, and open the sword to return to the sky.

The wind passed, and there was no grass, and in the blink of an eye, the number of resists of the imperial sword returning to the sky was gone, and it caused nine times of damage in one second, and with the number of resists of the first-order imperial sword returning to the sky, Shi Feng could not survive for two seconds.

And the Purgatory Demon and the Cursed Demon lose four or five hundred thousand health points per second, and the damage is terrifying.

"It's a pity."

The depths of the stone peak were in the black wind, and he was a little depressed in his heart, and he was only a little short of being able to open the stone door and enter, but he didn't expect the nine-headed demon snake to be so ruthless, and he used a third-order forbidden spell when he came up, and it was also a super-large destruction magic, so he didn't give a chance at all.

I saw the black wind strike again.

Suddenly, the triple magic array in the sky began to dissipate, and the black wind stopped abruptly and disappeared into nothingness.

Before Shi Feng could understand what was going on, the nine-headed demon snake in the distance let out a painful scream, turning into stone and shattering to the ground, and three items fell from it, shining in the rubble.

And Shi Feng's ears suddenly sounded a system prompt.

"It's ......"
