The body of the black ape was sixty feet tall. When the faint golden patterns lit up, it was as if it was plated with a layer of gold.

What was even more terrifying was that on the arm that had just been pierced by Su Yi, the blood was no longer flowing. If one looked carefully, it actually started to recover and become scarred.

"Is it because of the bloodline of the black ape?" Su Yi muttered. He had a hint of judgment about the state of the black ape.

Demon beasts were different from cultivators.

The strong and the weak depended on cultivation techniques and equipment.

Demon beasts, on the other hand, were simple and crude. They only cared about bloodlines. A powerful bloodline could allow demon beasts to fight above their current level.

At this moment, the diamond black ape seemed to activate the incomplete bloodline in its body to fight.

"Since you have activated your bloodline, let me see how strong you are!"

"Tiangang Six Swords!"

Su Yi said as he flicked his fingers.

In the blink of an eye, six Tiangang sword qi shot out from his fingertips, emitting a sharp air-piercing sound.

However, in the next moment...

Ding ding ding!

Six crisp sounds were heard. After Su Yi's Tiangang sword qi touched the golden barrier, it actually directly bounced away and dissipated, without any effect.

Roar!

When the diamond black ape saw that Su Yi was no threat to it, it let out another ferocious roar.

Its huge pale golden body kicked up a cloud of dust as it ran towards Su Yi.

"Interesting, let's see how long you can last!"

"Tiangang Six Swords!"

At this moment, Su Yi flicked his hands repeatedly. Each attack shot out twelve inches of sword Qi that flew towards the diamond black ape.

With his attributes, Su Yi did not believe that he could not break through the defense.

That defense earlier was definitely the effect of the diamond bloodline. However, the diamond black ape must have a limit to the use of this incomplete bloodline.

Therefore, at this moment, he only needed to ensure that he continued to attack.

Boom!

Ding ding ding!

In the area where the two sides were fighting, every attack of the diamond black ape would create a deep pit on the ground. Accompanied by Su Yi's continuous counterattacks, the crisp sounds of small collisions could be heard.

The battle seemed to have reached a stalemate, and neither side could do anything to the other.

However, gradually, the layer of golden shield of the black ape began to dim.

Su Yi's Tiangang Sword Finger was able to pierce through that layer of golden shield.

Not long after, when Su Yi used the Tiangang six swords again.

Bang bang bang!

Six bloody holes appeared on the huge body of the black ape.

"Have you reached your limit? Then let's end this!"

"It's a pity that you haven't awakened the true king kong bloodline," Su Yi said coldly.

The black ape seemed to have sensed something and stopped attacking. Instead, it revealed a trace of fear and turned around, wanting to escape.

Seeing this scene, Su Yi narrowed his eyes and stretched out his hand to grab the air.

At some point in time, a blood-red ancient flag with a primordial aura appeared in his hand.

"Trying to run?"

"Taiyuan ancient flag!"

Suddenly, the ancient Taiyuan flag floated up from Su Yi's hand and waved toward the black diamond ape. An ancient aura that was as deep as the abyss filled the entire area.

In an instant, the diamond black ape's huge body was frozen. It could not take another step forward, and no matter how it struggled, it was useless.

"Fifth move. Tiangang Sword Intent!"

Su Yi's true essence surged. When he lightly slashed at the black ape, a white sword qi emerged from his fingertip, emitting a majestic sword intent. A rainbow light pierced flashed across the sky and fiercely slashed at the black ape.

A white light flashed, and the giant body of the black ape seemed to freeze, no longer struggling.

A clear line of blood appeared on its entire body, and in the next instant, it split open and fell to the ground.

[Hint: You have killed the early-stage foundation establishment realm demon king -- diamond black ape.]

The Taiyuan ancient flag slowly fell from the sky and withdrew its ancient aura. It returned to Su Yi's body and let out a breath of turbid air.

The consumption of true essence was very large, and it was not just the Tiangang Sword Finger. The most important thing was to activate the Taiyuan ancient flag.

To imprison a creature of the foundation establishment realm, it required 8,000 true essence points. If it was not for condensing a wisp of innate superior clear qi, it might have sucked out all of his true essence.

"I must quickly refine the mystic condensing pill. When the time comes, I'll convert all the true essence in my body into innate superior clear qi. Then I won't be so tired when I activate the Taiyuan ancient flag!" Su Yi muttered to himself.

Then, he waved his hand to deactivate the spell and headed toward the diamond black ape's corpse.

[Hint: collection successful. Obtained early foundation establishment -- black ape demon king pill x 1, black ape demon king skin x 1, black ape demon king bone x 4.]

After harvesting, Su Yi surveyed his surroundings.

When the diamond black ape roared, the entire mountain of black apes had disappeared without a trace, leaving behind only the rumbling of the waterfall.

"Do you think you can escape?"

"Wait until I find this diamond black ape's nest, then I'll come looking for you all."

Before coming to the Demon Spirit Mountain Range, Su Yi had already learned that there were usually powerful demon beasts guarding the area where the full moon grass grew.

This diamond black ape's nest definitely had a large area of full moon grass. It could even contain other things. So, as long as he found its nest, he would be able to get what he wanted.

Thinking of this, Su Yi began to move. He began to explore around the place where the diamond black ape came from.

Not long after, when Su Yi circled around the waterfall branch and explored a cliff wall, he discovered something unusual.

Above him, there was a huge pitch-black hole that was covered by the waterfall.

"That should be the den of the diamond black ape!" Su Yi said affirmatively.

Then, he stepped on the ground and jumped into the hole.

When Su Yi looked over, he saw that the cave was long and pitch-black. It was just wide enough to fit the body of the diamond black ape.

At this moment, Su Yi walked into the cave. Not long after, he saw a few pieces of spirit stones that were emitting a weak light appear in front of him.

[Hint: You have obtained low-grade spirit stones x 10.]

"I can't wait to explore! This diamond black ape definitely has something good."

After placing the spirit stones into the immortal destiny seal, Su Yi continued to walk forward.

Not long after, after turning a corner, he saw a piece of grass that was emitting a gentle light and had silver patterns on its branches.

"Full moon grass."

Su Yi's eyes lit up. This was the missing herb from refining the mystic condensing pill.

[Hint: You have collected full moon grass x 2.]

[Hint: You have collected full moon grass x 3.]

...

After collecting all of it, Su Yi obtained more than 50 sets of full moon grass.

Then, he continued to explore ahead. However, not long after, other than finding about 20 low-grade spirit stones, he actually did not find anything else.

'How is this possible! Even the full moon grass is gone?'

'There are only so few things in the foundation establishment demon king's nest? Could it be that someone came to this nest some time ago?' Su Yi frowned and thought to himself.

At this moment, the gains in the nest obviously did not fit the normal situation. There was only one possibility. Not long ago, a cultivator must have come to collect the things in the nest.

In the secret region, there was a group of cultivators who often did this sort of thing. Instead of killing demon kings, they explored all kinds of demon king nests.

That was because killing demon kings did not yield much, other than obtaining demon king materials.

On the contrary, exploring demon king lairs and nests allowed them to obtain resources, which was more cost-effective.

"Oh, no. This full moon grass isn't enough for me to refine the mystic condensation pill."

"Unless I'm looking for other demon king nests... but the Demon Spirit Mountain Range is so big, it's hard to find them."

Su Yi frowned as he pondered, but in the next moment, he seemed to remember something. He took out a scroll with mountains, rivers, sun, moon, and stars from the immortal destiny seal.

[Treasure: Mountain and river painting (Top-grade).]

[Description: Mountains, rivers, sun, moon, and stars, the Great Dao immortal destiny, all in this map.]

[Effect: After using, you can activate your immortal destiny and enter the land.]

[Top grade: Increase the chance of rare immortal destiny by 100%.]
