One person: Starting with the Rumble-Rumble Fruit, his grandmaster uncle emerges from seclusion.

Xu Xin.

"Old man."

Zhang Tianyi's tone conveyed a sense of nonchalance and casualness.

"Just now, Master Tang praised your skills to the skies, saying they were unparalleled in the world. It made me really eager to try them."

"Anyway, you've been squatting in this dark cave for decades, doing nothing but thinking about this thing all day. Your skills should be top-notch by now, right?"

Zhang Tianyi raised his chin and beckoned to Xu Xin with his finger.

"Come on, stop hiding it."

"Place it facing me."

"Let me see what this most potent poison in the world, which is said to be incurable even by gods, tastes like."

Everyone in the Tang Clan looked at Zhang Tianyi as if he were a madman.

Xia Liuqing and Tu Junfang from Quanxing were also very surprised.

That's Dan Shi!

It is colorless and formless; once it takes effect, death is certain!

This Celestial Pivot Master actually asked the other party to poison him?!

"Master...Master!"

Zhang Chulan stood behind, his palms sweating.

Although he knew his advisor was ridiculously powerful, this thing had actually taken his grandfather's life back then!

"Please take it easy, old man! This is no joke!"

Zhang Chulan was so anxious that he stomped his feet, wanting to go up and stop him, but he didn't dare to.

On the stone bed.

Xu Xin's somewhat cloudy eyes stared silently at Zhang Tianyi.

He endured over seventy years in that dark, sunless cave, living like a living dead.

For more than seventy years, he had no contact with the outside world and no normal life.

His only solace was Dan Shi!

After decades of honing his skills, he asked himself if his current Dan Shi (a skill) had already surpassed that of all the previous Tang Clan predecessors.

It could even be said that it reached a pinnacle of achievement.

Facing this legendary killing god whose appearance has not aged.

Xu Xin slowly stood up. Although he was thin and bony, he exuded a sense of danger that made people's hearts tremble as he stood on the stone bed.

"Tian Shu Zhenren..."

On Xu Xin's gaunt face, the muscles twitched slightly, and his voice, though hoarse, carried a hint of the fervor of an assassin:

"It has always been a regret of mine that I never had the chance to witness the unparalleled skill of a real person tearing apart the Yin-Yang Bureau back then."

"Since the Master insists on personally instructing you today..."

Xu Xin forced a somewhat stiff, cold laugh and clasped his hands in a fist salute:

"Then this old man will dare to use the highest secret technique of the Tang Clan to experience the supreme divine power of the True Man!"

The voice just fell.

Xu Xin didn't make any unnecessary movements, not even lifting a finger.

But at that moment, the air in the entire cave became strange.

There were no visible fluctuations in the flow of Qi.

But it's a chilling intuition.

A chilling aura of death was silently spreading outwards from Xu Xin's center.

"Retreat! Everyone, retreat!"

Zhang Wang shouted loudly and hurriedly told the Tang Clan disciples to retreat.

The Quanxing gang was even more slippery, having already clung to the stone wall at the very edge of the cave.

"This is the Pill Devouring..."

Zhang Chulan stared intently at the center of the arena, not daring to blink, his heart pounding wildly.

Zhang Tianyi stood less than three meters away from Xu Xin.

He simply opened his arms wide, as if welcoming a gentle breeze.

"Come on," Zhang Tianyi chuckled.

next second.

Zhang Tianyi keenly sensed that there was an extremely hidden energy, like an invisible needle.

It silently penetrated his skin and went straight into his body.

Once this energy enters the body, it's like a maggot clinging to the bone, heading straight for all the major meridians and vital points around him!

Its purpose is clear: to completely destroy the body's Qi circulation system in the shortest possible time, thereby fundamentally undermining vitality!

This is what makes Dan Shi so terrifying!

Zhang Tianyi stood there motionless.

A look of relief and satisfaction finally appeared on Xu Xin's old face.

I've been infected.

Once the pill enters the body, even a great immortal will have to leave their life here!

His more than seventy years of sitting in meditation, his day and night of deduction, have finally paid off!

"Ugh……"

Tang Miaoxing sighed heavily beside him, closed his eyes, seemingly unable to bear seeing this master of the Celestial Master's Mansion die tragically on the spot.

however.

The anticipated scene of Zhang Tianyi bleeding from all seven orifices and collapsing convulsing did not materialize.

Ten seconds or so passed.

Zhang Tianyi remained standing there steadily.

Instead of collapsing, he scratched his chin with a hint of boredom.

"Old man."

Zhang Tianyi lowered his hand, looking at Xu Xin on the stone bed whose expression was gradually stiffening, his tone full of disappointment:

"You've been holed up in that cave for over seventy years, and this is all you've come up with?"

"This is impossible!"

Xu Xin's eyes widened suddenly, and his voice changed.

"The Dan Shi has entered your meridians! It should be disrupting your Qi circulation! How could you be alright?!"

"Damaging the meridians?"

Zhang Tianyi chuckled.

"Old man, your idea for poison is indeed quite ingenious."

Zhang Tianyi put his hands back in his pockets and said slowly and deliberately:

"But your poison is used to damage the body's meridians."

"But……"

Zhang Tianyi's lips curled into a mischievous smile.

He slowly raised his right hand.

Under the horrified gazes of everyone.

Zhang Tianyi's right hand began to turn transparent, starting from the fingertips.

Flesh, bones, and blood—all vanished!

It turned into lightning!

Elementalization!

"I'm sorry."

Zhang Tianyi shook his arm, which was made entirely of lightning, and said in a very irritating tone:

"Master Dao, in my current body..."

"Only Thunder!"

"boom!"

As Zhang Tianyi finished speaking.

The vast and boundless innate lightning energy within his body suddenly circulated once.

Those poisonous Qi that had seeped into his body, supposedly incurable in the world.

When encountering this extremely masculine and powerful innate thunder element.

A soft "sizzle" sound.

It was burned to ashes, turning into nothingness.

Not to mention destroying any life, it didn't even harm a single hair on Zhang Tianyi's head!

"..."

Xu Xin stood blankly on the stone bed, staring at Zhang Tianyi's thunderous arm.

His withered lips trembled, and his mind went blank.
