Lin Xiaofei swaggered through the mountains, quickly approaching.

Roar! Roar! Roar!

The fourth-tier Netherworld Beast was taken aback. Seeing a human cultivator walking freely in its territory, it roared in anger.

In its furious outburst, it leaped forward like a black shadow, swiftly pouncing towards Lin Xiaofei.

At the same time, it opened its huge mouth and spat out a dark light, which transformed into a huge black hailstone that crashed down on Lin Xiaofei.

boom!

As black hailstones were about to fall, Lin Xiaofei casually unleashed a sword aura, instantly shattering the dark light.

"Not bad, the power of this sword energy can finally withstand the attack of a fourth-tier early-stage Netherworld Beast."

Lin Xiaofei smiled.

The dual domains opened instantly, and the spiritual power within his body surged forth, causing his aura to rise rapidly, as if soaring into the sky.

The fourth-tier Netherworld Beast trembled continuously, its fur flying rapidly into the sky.

The dark hairs transformed into countless sharp arrows, each over three zhang long, piercing the void and shooting towards Lin Xiaofei in a massive, overwhelming barrage.

Lin Xiaofei took a step forward, his figure like a phantom, leaping at lightning speed, dodging left and right, quickly avoiding the arrow-like attacks.

As he dodged, he quickly approached the Netherworld Beast, and with a wave of his hand, a dark red longsword transformed into a beam of laser sword energy, shooting out.

Great divine power, the Demon Blood Great Divine Sword.

The Netherworld Beast showed no fear; it opened its massive maw and unleashed a beam of dark light.

At the same time, its body leaped forward like a black shadow, quickly rushing up and directly colliding with that sword energy.

puff!

The sword energy sliced ​​a two-zhang-deep gash into its body, causing blood to splatter.

boom!

The Netherworld Beast was hit by a huge impact and was sent flying more than two hundred feet away in an instant, crashing heavily to the ground with a loud bang and letting out a miserable scream.

Although its physical body is comparable to a top-grade Nascent Soul treasure, this sword energy has barely reached the level of a strike from a Nascent Soul cultivator in the early stage.

After all, Lin Xiaofei's spiritual energy purity had been greatly improved, which caused the power of the sword energy to increase rapidly.

"The successful cultivation of the Spiritual Image True Technique has increased the purity of my spiritual power, which has also greatly enhanced the power of my great supernatural abilities."

With the improvement in my realm, my strength has also been enhanced.

That attack just now was able to pierce the body of a fourth-tier Netherworld Beast, which means my attack power has reached the level of the Nascent Soul stage.

Lin Xiaofei thought to himself, and then he made an assessment of his own strength.

roar!

The Netherworld Beast flipped over and leaped, staring intently at Lin Xiaofei with a fierce glint in its eyes. It roared and its entire body emanated a terrifying demonic aura.

Immediately, he leaped forward and pounced on Lin Xiaofei.

With a thought, Lin Xiaofei unleashed the Black God Sword, transforming it into a streak of black light that sped away.

The Nether Beast suddenly froze, as if sensing a great danger. It immediately opened its mouth, preparing to condense a terrifying dark light.

puff!

The Black God Sword pierced straight through its mouth.

boom!

Immediately, it fell heavily to the ground, letting out a miserable scream.

At this moment, it couldn't stand up and was thrashing and rolling on the ground.

Lin Xiaofei moved swiftly, arriving beside the Netherworld Beast, and condensed a laser sword aura in his hand.

"Awoo..."

When the Netherworld Beast saw Lin Xiaofei approaching, it let out a mournful howl, sensing the approaching aura of death.

It was terrified and panicked.

It desperately wanted to stand up and escape, but its internal organs were shattered by the Black God Sword, causing its strength to rapidly dissipate, making it impossible for it to stand up.

Is he scared?

Unfortunately, I won't let you go.

Lin Xiaofei said it casually.

The sword energy in his hand descended rapidly, like a rainbow.

puff!

The sword energy was like a sharp blade, directly severing the head of this fourth-tier Netherworld Beast.

"With my current strength, I no longer need to be afraid when I encounter fourth-tier Netherworld Beasts again, and I can even fight them in a big battle."

However, Netherworld Beasts at the mid-stage of the fourth tier or higher may not be a match for them at present.

Lin Xiaofei felt secretly pleased after killing the Netherworld Beast, which was at the early stage of the fourth tier.

This is the power, and the pleasure it brings him.

Lin Xiaofei glanced at the corpse on the ground, then casually waved his hand and put it into his storage bag.

He tested his abilities, which greatly boosted his confidence.

With a flash, he headed towards the outer edge of Netherworld Mountain.

He had searched almost every second-grade spiritual herb deep within the Netherworld Mountain, and now he decided to leave.

An hour later, Lin Xiaofei arrived at the central edge of the Netherworld Mountain.

This time, he plans to explore the outer area as well to see if he can find any more Grade 2 Netherworld Grass.

After quickly circling the mountains, he felt that this time, he had almost completely searched out all the second-grade Netherworld Grass in the entire Netherworld Mountain.

"Unfortunately, there aren't many Grade 2 Netherworld Grasses in the outer area; only a little over 50,000 were found in total."

Lin Xiaofei sighed, looked at the second-grade Netherworld Grass that had just been planted in the spatial bead, and then smiled slightly, muttering to himself:

In any case, the spatial bead is finally filled with one million second-grade spiritual herbs. In another two or three days, it will be able to be used for cultivation again.

He knew in his heart that he had gained tremendous benefits from this trip to the Netherworld Mountain.

However, once he leaves Netherworld Mountain, he expects to be hunted down by the Bitter Sea Ancestor.

Although he can now exert the strength of an early-stage Nascent Soul cultivator, it is still uncertain whether he can contend with the Bitter Sea Ancestor.

After thinking about it, he estimated that he was only about 50% confident that he could contend with his opponent.

"I'm 50% sure. Although there are some shortcomings, the other side can't do anything to me."

Lin Xiaofei thought to himself.

In his view, his own strength was already not much weaker than that of the Bitter Sea Ancestor.

Moreover, since the Old Ancestor of the Bitter Sea lost an arm, he certainly cannot recover it in a short time, so the opponent's strength will be somewhat diminished.

Therefore, he doesn't need to be afraid of the other party.

Furthermore, if he were to encounter a life-threatening situation, he could simply retreat into the Netherworld Mountain to hide, or enter the spatial bead.

After figuring it out, he swayed and gradually emerged from the depths of the outer perimeter of Netherworld Mountain.

...

“Ancestor of the Bitter Sea, we have been waiting at the entrance of the Netherworld Mountain for three days, but we still haven’t seen the Black God True Monarch come out.”

I wonder, what if the Black God True Lord keeps hiding inside and doesn't come out?

Are we supposed to stay here and guard him forever?

After glancing at Netherworld Mountain, True Lord Dahai respectfully addressed Old Ancestor Kuhai beside him.

Previously, he had followed the Old Ancestor of the Bitter Sea in hunting down the Black God True Monarch, but without any success, which made him somewhat anxious.

"Don't worry.

There is almost no spiritual energy in the Netherworld Mountain. If he stays there for a long time, he will surely die once his spiritual energy is exhausted.

I think he won't wait until his spiritual energy is completely depleted before coming out.

I estimate that he can only stay inside for another half a month at most before he comes out.

Now, we've set up a trapping formation near the entrance to Netherworld Mountain. As soon as he comes out, he'll inevitably enter the formation.

"Old Ancestor of the Bitter Sea," he said calmly.
