Urban Divine Doctor Descends the Mountain

Chapter 3109: Chapter 3109: Nine Tribulation Thunder Stone

Afterward, Lin Dong followed closely behind Fengtian, continuing forward in this Black Abyss.

The surroundings were filled with an oppressive and eerie atmosphere, as if even the air had solidified into substance, with each step feeling like he was treading on the edge of another world.

Along the way, some weak "unknown creatures" occasionally emerged from the darkness, each with different forms and eyes flickering with a ghostly green light.

Upon seeing the outsiders, they indiscriminately began to attack Lin Dong and Fengtian.

Faced with their provocation, Fengtian did not hesitate at all and slaughtered them.

Leaving behind only one by one, the faintly glowing red "Blood Soul Crystal Stones."

Lin Dong was responsible for collecting these Blood Soul Crystal Stones.

Fengtian didn’t want them, but he really needed them.

As they delved deeper, the number of Blood Soul Crystal Stones in Lin Dong’s hand gradually increased, accumulating to dozens in the blink of an eye, heavily packed in a special storage bag.

In this Black Abyss, where the sun was almost unseen, time seemed to lose its meaning.

Lin Dong could no longer remember how long they had been walking, only knowing that the environment around them kept changing, from rugged rocky ground to swampy areas filled with strange plants, and now, surprisingly, in front of them was a tranquil and mysterious lake.

The lake’s surface was calm as a mirror, but its color was distinctively different from the usual, being a pure black that made one’s heart palpitate, seemingly capable of devouring all light and causing a chill in the heart.

Staring at this scene, Lin Dong couldn’t help but blurt out, "Lord Fengtian, there’s actually a lake in this Black Abyss?"

"And the lake water, it’s actually black."

His tone was mixed with surprise and awe for the unknown.

Fengtian slightly turned her head, her gaze deep as if she could discern the secrets behind this lake.

"The Black Abyss is a place where miracles and dangers coexist. It holds many unique characteristics, like those dark rifts that can tear space, and now this Dark Abyss Lake... These places, even for me, are not easy to tread lightly upon because they hide risks beyond estimation."

"However, as the saying goes, danger often accompanies opportunity, and under this lake, there might be some supreme treasures hidden."

"Treasures that even our Secondary Ancestors covet..."

As she spoke, her eyes glimmered with light, pondering whether to dive into the lake and explore a bit.

Hearing this, Lin Dong focused more intently on that mysterious lake.

At this moment, his gaze was drawn to a peculiar stone in the lake.

The stone floated solitary on the lake’s surface, its exterior enveloped by a thick layer of black substance.

But beneath that black layer, faint flashes reminiscent of lightning appeared intermittently, like the most distant stars in the night sky, mysterious and enticing.

Lin Dong’s heartbeat involuntarily accelerated, as memories from ancient books he had once read flashed quickly through his mind. It was a... Nine Tribulation Thunder Stone!

Legendary Nine Tribulation Thunder Stone, the main herb for refining the Nine Tribulations Thunder Soul Pill, which significantly enhances mental power.

Moreover, it’s also something that can aid in overcoming a bottleneck!

Lin Dong’s next small mental power bottleneck would occur at the forty-fourth-stage peak of mental power. To ascend from the forty-fourth-stage peak to the forty-fifth stage, he must endure a small mental power bottleneck.

The next major bottleneck would be at the forty-ninth-stage peak of mental power. To breakthrough from the forty-ninth-stage peak to the fiftieth stage, he must overcome a major mental power bottleneck.

However, to cross such a major bottleneck, relying solely on time for cultivation is like a never-ending journey.

But with the ’Nine Tribulations Thunder Soul Pill,’ it would be different. Having it could help Lin Dong smoothly overcome that ’major mental power bottleneck.’

As for the main herb of the ’Nine Tribulations Thunder Soul Pill,’ it is the Nine Tribulation Thunder Stone.

The Nine Tribulation Thunder Stone is inherently a gemstone of excellent quality, having endured nine baptisms of heavenly thunder, eventually forming the ’Nine Tribulation Thunder Stone.’

The formation of each Nine Tribulation Thunder Stone takes at least several hundreds of thousands of years. Or even longer!

"Lord Fengtian, what’s... what’s that stone? It’s astounding, actually floating on the water, emitting the power of thunder and lightning." Lin Dong’s voice carried a touch of disbelief, unable to conceal his excitement.

He pretended not to recognize the stone while inquiring Fengtian, aware that she was also intently observing the stone.

Thus only as ’acting.’

Fengtian’s gaze was serious, clearly noticing the unusual stone as well.

"That’s a Nine Tribulation Thunder Stone! It’s my first time seeing one too!"

"It’s said to be the main ingredient for refining the sixth-grade pill, the Nine Tribulations Thunder Soul Pill, a kind of pill used to boost mental power."

"It’s rumored that only under extreme conditions where thunder and darkness intertwine can it possibly emerge, needing to be baptized by the Nine Heavens Tribulation."

"Yet, even so, the Nine Tribulation Thunder Stone naturally floating on the water surface is exceedingly rare. Beneath this lake, there might be secrets far more complex than we imagined."

Hearing this, Lin Dong’s eyes flickered.

Fengtian’s words made sense; since this place could nurture a ’Nine Tribulation Thunder Stone,’ then it’s surely extraordinary.

Lin Dong must not fixate only on the allure of the ’Nine Tribulation Thunder Stone’ and overlook the danger here.

He comprehended that once it involves such treasures as the Nine Tribulation Thunder Stone, it surely accompanies unimaginable risks.

However, this Nine Tribulation Thunder Stone is extremely crucial to him. Obtaining it, and refining the ’Nine Tribulations Thunder Soul Pill,’ would allow Lin Dong to smoothly breakthrough to mental power stage fifty.

Otherwise, contemplating the leap from the forty-ninth-stage peak of mental power to stage fifty would be as hard as reaching the sky.

Since the mental power stage fifty major bottleneck, it is like an insurmountable chasm!

"Lord Fengtian, should we give it a try? To obtain that Nine Tribulation Thunder Stone? Moreover, explore this Dark Lake, there might be some treasures inside." Lin Dong seemingly casually suggested.

Fengtian contemplated briefly, seemingly weighing the pros and cons.

Since this Dark Lake could birth ’Nine Tribulation Thunder Stone,’ might it also birth other treasures?

Could there possibly be more precious treasures underwater?

Fengtian felt a bit tempted.

In some special places within the Black Abyss, it is very possible for items so coveted by their Secondary Ancestors to emerge.

Since they’ve reached this point, she really wants to explore this Dark Lake and see what lies beneath.

Finally, she slowly nodded, saying to Lin Dong, "It’s worth a try, but we must be cautious."

"Peach, stay behind me. Remember, in the Black Abyss, danger might lurk beneath any seemingly calm surface. We need to seek opportunities but also protect ourselves."

Lin Dong nodded heavily, feeling more assured with Fengtian ’leading the way.’

"It seems that following Fengtian into this Black Abyss isn’t all bad. At least, she can serve as a ’fighter’ and a ’guinea pig.’" Lin Dong thought to himself this way.

Currently, he regards Fengtian as an invisible ’guinea pig,’ letting her scout ahead.

Moreover, she does so willingly.

"Let’s go, follow me. Stay close, don’t stray beyond three steps from me, or I can’t protect you." Fengtian instructed.

Lin Dong leaned closer, sticking to her, and said, "Alright, Lord Fengtian. I’ll definitely keep close to you."

With Lin Dong’s response, Fengtian began moving forward with Lin Dong.

The two of them cautiously approached that Dark Abyss Lake.

The lake water rippled slightly in the gentle breeze, as the Nine Tribulation Thunder Stone floating above the lake surface quietly emitted weak yet alluring light, as though waiting for something.

Beneath the dark lake water, some sort of unknown, also seemed to be waiting for something.

As they stepped into the Dark Lake, its currents began to surge...
