In the sky filled with red mist, Lin Hao flew forward without stopping.

He couldn't help but feel amazed at the vast space in the secret realm.

With such an area, even the main island areas of the nine major sects are probably far smaller than it.

Lin Hao really couldn't imagine that such a huge secret space was contained within an altar.

From this we can see how powerful the martial arts masters of ancient times were!

After a long flight, Lin Hao's physical energy was consumed very quickly.

Fortunately, I had enough dry food in my storage ring.

He took out a piece of smoked animal meat and was about to fill his stomach when he suddenly heard some faint noises coming from not far away.

Because the red fog was too thick, it was impossible to see clearly.

Lin Hao listened attentively, it seemed to be the sound of gurgling water.

“Is there a river here?”

Lin Hao was slightly surprised, and immediately put away the piece of meat and flew towards the sound of water.

About a hundred feet away, Lin Hao quickly found the source of the sound.

There is indeed a river here.

Not too big, not too small, crossing the area ahead.

But the water in the river is not the same as that in ordinary rivers. It is like mercury and seems a little sticky.

Lin Hao bent down, covered his palm with spiritual energy, and tried to scoop up a handful of water.

Suddenly I felt the water was extremely heavy, and its temperature was as hot as magma.

With a "hissing" sound, the spiritual energy protection layer covering Lin Hao's palm was mostly melted away in just a few breaths.

Seeing this, Lin Hao's face changed slightly and he hurriedly shook off the river water in his palm.

"What a strange river!"

There was a hint of surprise in Lin Hao's eyes. This secret realm of Heavenly Fire was really difficult to understand with common sense.

"There are creatures out there!"

Immediately, Lin Hao discovered from the corner of his eye that there were living creatures deep in the river.

A giant red crocodile, covered with scales, with a huge head, and a ferocious and ugly look.

The two rows of dense teeth that looked like fangs extended out of the mouth and were extremely creepy.

At this time, the giant crocodile was lurking at the bottom of the river, staring at Lin Hao on the shore with its pair of scarlet eyes.

In that situation, it was obvious that Lin Hao had been treated as prey.

“Gurgle~!”

Its mouth opened and closed, making strange noises.

Soon, dozens of giant red crocodiles gathered in the river.

Seeing this, Lin Hao hurriedly flew into the air, increasing the distance between him and the river.

"Look, there's a river."

At this time, many inner hall disciples who followed closely also discovered this strange river.

They all stopped and looked at it with curiosity, trying to find resources.

The newly-initiated inner hall disciples behaved in the same way as Lin Hao had just done. They walked to the river curiously and scooped up some river water.

"Don't get too close. The water beasts in the river are very aggressive..."

Seeing the actions of the newcomers, Zhu Yun quickly reminded them.

Crash——!

However, before he could finish his words, there was a sudden splash on the surface of the river.

Dozens of giant crocodiles, which had been ready to attack, suddenly jumped out of the water and pounced on the crowd on the river bank.

At this time, the inner hall disciple was amazed that the river water in his palms could dissolve the spiritual energy.

I was caught off guard by the sudden change.

Even though they reacted extremely quickly, several of them were unable to dodge in time.

The ferocious crocodiles bit his head directly with their ferocious giant mouths, and his body was torn apart on the spot!

Seeing this, everyone's pupils suddenly contracted.

At that moment, figures retreated in panic, away from the river.

"This beast is a red-scaled crocodile from ancient times. It is ferocious by nature, and its strength is between the Spirit Infant Realm and the Star Realm for us human warriors."

Zhu Yun said solemnly: "Although eating their flesh and blood is very nourishing to us, we also have to consider whether we can handle it."

Hearing this, the inner hall disciples around him swallowed their saliva secretly with their throats rolling.

After seeing the dangerous scene just now, how could they have the courage to capture him, especially in the extremely corrosive river water.

I'm afraid that before I can catch it, the protective spiritual energy shield on my body will be dissolved by the strange water.

"Let's go."

At present, almost no one is attached to the resources here and they all choose to move on.

In the field, Lin Hao was the only one who remained still in the same place.

"Such good evolutionary feed cannot be wasted."

When everyone completely disappeared in the red mist, an intriguing smile appeared on Lin Hao's lips.

He had no appetite for this ugly crocodile meat, but it was undoubtedly a great tonic for the system pets!

Moreover, the red-scaled crocodile is not that strong, and the combat power of Jing Ke and other beasts is more than enough to deal with it.

"Foodies, come out and eat."

Immediately, Lin Hao called out.

Jing Ke, Mantis King, Tiger Tyrant, and Ant King.

This pet group makes a grand debut!

Fierce beasts have a natural sensitivity to the strength of their own species.

Feeling the powerful aura of Jing Ke and other beasts, the red-scaled crocodiles were not stupid. They all hid at the bottom of the river and gathered together.

In their opinion, as long as they hide in the water, they are in the safest area.

Hu Ba walked to the shore with mighty steps, staring at the red-scaled crocodile at the bottom of the river with his scarlet eyes, revealing a hint of bloodthirsty ferocity.

Immediately, brilliant lightning flashed all over its body, and thick red arcs surrounded it wantonly.

"roar!"

Then, Hu Ba roared, and the lightning arcs surging around his body immediately set off a huge red storm, carrying terrifying energy fluctuations, and directly slammed into the river.

As the saying goes, water conducts electricity.

What’s more, it is this extremely terrifying power of thunder.

In an instant, lightning spread out, and a huge whirlpool formed in the entire river.

Under the impact of thunder, the red-scaled crocodiles hiding in the water rushed out of the water howling and quickly crawled to the shore.

However, without the obstruction of strange water, their appearance undoubtedly became a hunting feast for Jing Ke and other beasts.

All of a sudden, all the red-scaled crocodiles were killed instantly.

Especially Hu Ba, whose combat power is 100,000, which is comparable to the fourth level of the holy realm of human martial artists.

Hunting these red-scaled crocodiles is like swatting a fly.

With a fierce slap from the tiger's paw, the entire crocodile head was instantly smashed to pieces and then swallowed directly.

Lin Hao was suspended in the air, watching the whole process indifferently.

And its spiritual awareness also covers the visibility area in a certain radius to prevent outsiders from breaking in and discovering the existence of Jing Ke and others.

Just like that, after about a moment.

All the red-scaled crocodiles that came ashore were hunted to death.

There was blood all over the ground, but no animal corpses were seen.

On the other hand, Jing Ke and the others were glowing with light. It was obvious that their evolutionary value had been fully accumulated and they were beginning to transform.

"Ding, congratulations to pet codename 001 Jing Ke, who has completed his evolution and transformation, and his combat power has been comprehensively improved!"

"Ding, congratulations to the pet mantis king codenamed 002, the transformation is complete, and the forelimbs have been strengthened with metal!"

"Ding, congratulations to codename 003 pet Tiger Tyrant, who has successfully evolved. The blood of the Beast King has increased to 60%."

"Ding, congratulations to codename 004 Pet Ant King for advancing to Violent Beast Mad Ant."

Suddenly, a series of system prompts sounded in Lin Hao's mind.

The bodies of the four pets have also undergone a complete transformation.
