The powerful sword energy of this sword did not dispel the poisonous fog, but instead quickly squirmed and directly wrapped around the sword body.

In just a few breaths, the metal sword was completely corroded.

"What?!"

The long-haired young man's pupils shook violently, his hand quickly loosened the hilt of the sword, and he quickly stepped back.

His face, which was full of confidence just now, now couldn't help but show a hint of surprise.

"What a strong poison gas."

Seeing this, everyone was secretly surprised.

Even spiritual swords were corroded beyond repair in this poisonous fog. They were not completely sure that the protective spiritual shields on their bodies could withstand it.

Once the defense is broken, with only flesh and blood left, the consequences would be extremely tragic!

Thinking of this, no one had the courage to rush directly into the poisonous fog.

"It's useless. These fire poisons are very corrosive and cannot be dispelled by ordinary attacks."

The Huoyun Sect disciple shook his head and said, "Unless we use the Devouring Martial Arts, we can eliminate them all."

After saying this, most of the eyes were directed towards the people from the Dark Palace in almost tacit understanding.

This is because the Devouring Martial Arts belongs to the dark-type technique, and the training conditions are extremely harsh. It can only be performed when the spiritual power in the body is transformed into dark attributes.

Therefore, under normal circumstances, this kind of skills are more suitable for the Dark Temple's cultivation system.

However, facing everyone's expectant eyes, the long-haired young man from the Dark Palace Sect and others looked at each other in bewilderment. It was obvious that no one knew how to practice this evil technique.

For a while, the situation was at a stalemate.

Boom boom boom!!!

At this time, the heavy sound of running coming from the rear passage gradually approached, making the expressions of these temple disciples suddenly become tense.

Weapons such as swords and knives all appeared in their hands, and as their spiritual power surged, they emitted a powerful aura.

With danger imminent, they no longer have the energy to dispel the poisonous fog and search for treasure!

Faced with the arrival of alien races, the disciples of the Palace Sect, who have always fought openly and secretly, now work together.

As expected, the orc team finally caught up here.

The long and narrow passage was suddenly blocked tightly by this group of strong orc warriors.

Staring at the hundreds of human warriors in front of them, their eyes revealed fanatical excitement.

That expression was like a ferocious hungry beast that had found its prey!

"kill!"

Without any nonsense, the leading werewolf warrior raised his wolf-fang-shaped long sword and roared in a low voice.

At that moment, more than a hundred orc warriors swarmed forward, roaring.

"Fight them!!"

The disciples of the Wufang Palace Sect did not show any fear and went straight to the front to attack.

Although humans are relatively weak in terms of physique, they can make up for this gap through the cultivation of martial arts and spiritual power.

BANG BANG BANG!!!

Suddenly, the sound of metal clashing resounded violently in the passage.

In the back, Lin Hao watched indifferently, glancing at the dark red poisonous fog at the end of the passage. He had no intention of using the devouring martial arts.

This is a good opportunity to explore the space inside the passage alone.

"Jing Ke."

Lin Hao's mind moved slightly, and at the same time as Jing Ke was summoned out, he suddenly used instant movement and disappeared out of thin air with him.

With Jing Ke's current combat power, the distance he can teleport at a time can reach more than ten feet.

When Lin Hao's body flashed out, he only felt a dark red color in front of his eyes. The surrounding fog was thick, completely blocking his vision.

Obviously, he was already in the poisonous fog at this moment.

“Shhhhh…!!”

Suddenly, bursts of violent corrosion sounds rang out wildly.

The spiritual energy shield on his body was gradually dimming at an alarming speed.

From this we can see that the corrosiveness of these fire poisons is indeed extremely terrifying.

Moreover, even though he was protected by the spiritual energy shield, Lin Hao could still feel the air was extremely hot and his skin felt tingling.

Immediately, Lin Hao's spiritual power was running to the extreme, trying his best to support the spiritual shield, while Jing Ke took him to teleport continuously.

Finally, when he was about to collapse, there was no poisonous fog around the place where he teleported this time.

The air temperature also returns to normal.

Lin Hao looked around and saw that this was a cave in the mountain.

The space inside the cave is extremely vast, like a palace.

The sound of fierce fighting outside continued.

Lin Hao didn't care and looked around warily.

The surrounding stone shelves were almost filled with various bottles and jars, each labeled with the name of a pill.

Obviously, in ancient times, this should have been the place where the Yanfeng Palace stored elixirs.

These bottles and jars are made of metal castings. Despite thousands of years of erosion, they have been preserved to this day with excellent quality.

However, the pills inside are not the same.

Lin Hao picked up a bottle and the moment he opened it, a pungent smell filled the air.

The pills inside had turned into powder. They were all out of their shelf life and had degenerated into medicinal residue.

After some investigation, the same was found for the pills in the other bottles and jars.

Soon he wandered around, shuttling between each row of stone shelves, trying to find something valuable among them.

After working so hard for a long time, you can't get nothing in return.

However, the reality dealt him a heavy blow.

"This time, it looks like this trip is in vain."

Lin Hao shook his head, feeling secretly emotional.

When he reached the last row of stone shelves, Lin Hao suddenly noticed an iron door on the left side of the corner.

The iron gate was solid and thick, and was covered with intricate fire runes, undoubtedly some kind of protective formation.

Lin Hao had an indifferent expression, holding Jing Ke in his palm, and with the use of instant movement, he passed straight through.

After a brief blur of vision, a flash of fire suddenly appeared in front of Lin Hao's eyes.

Here, there is actually a pool of magma.

In the pool which was several feet wide in diameter, the red magma rolled violently, emitting an extremely terrifying high temperature.

However, what attracted Lin Hao's attention was not the magma pool in front of him, but a round stone floating above it.

If it was an ordinary stone, Lin Hao would be able to tell it at a glance.

On the other hand, the surface of this round stone has a texture similar to that of animal eggs.

At this time, the stone egg was suspended in the void, and the scorching breath rising from the magma was slowly absorbed.

Faintly, one can see that there seems to be some kind of animal spirit inside.

It looks a bit creepy.

"Could this be a petrified beast egg?"

Lin Hao felt quite strange and asked suspiciously, "Long Ling, can you sense it?"

Soon, Long Ling's deep voice sounded in his mind: "Dear Master, this beast pattern should be the egg of the Fire Phoenix."

"However, it is already a dead egg. The function of this magma pool seems to be to hatch it again."

Fire Phoenix Egg? !

Hearing this, Lin Hao's pupils constricted and he stared at the stone egg with shock in his eyes.
