Immunity to all poisons was just an added benefit.
The main benefit was immunity to both ice and fire.
With his Elemental Martial Soul, no poison could affect him anyway.
Qin Yun's Soul Power had also risen three levels, reaching level forty-seven.
More than ten days had passed since he left the Seven Treasure Glazed Tile Sect for Heaven Dou Academy, then followed Dugu Bo to the Ice and Fire Yin Yang Well.
He had been away training for quite some time.
If he stayed in the hidden realm any longer, Ning Fengzhi would surely grow worried and send people to search for him.
So he decided to return to the Seven Treasure Glazed Tile Sect first.
After some time had passed, he could check whether his experiment had succeeded.
Alone, he made his way down the steep cliffs surrounding the Ice and Fire Yin Yang Well.
On the way in, Dugu Bo had led him the whole way, his Titled Douluo pressure blanketing the forest.
Every Soul Beast deep in the woods had hidden away, too frightened to make a move. The mountain path had been perfectly safe.
But things were different now.
On his own, Qin Yun was exposed to this wild forest teeming with Ferocious Beasts.
The forest was deep and silent, its ancient trees towering overhead.
A cold wind rustled through the trees. Deadly threats lurked among the swaying plants.
Low growls and roars rose from the depths of the forest, full of savage menace.
Sure enough, when he reached a narrow pass halfway down the mountain, a fierce black shape burst from the trees beside him and blocked his path.
It was an enormous Blackflame Thunderstripe Tiger, powerfully built and covered in hard, ink-black scales and fur. Fine, pale-purple lightning patterns ran across its coat, and its four claws were sharp as blades.
It was unmistakably a Ten-Thousand-Year Soul Beast with formidable strength.
Its eyes were bloodred, its fangs bared and saliva dripping from its jaws. Its gaze locked on Qin Yun's slender figure.
Without hesitation, it drove its limbs against the ground and lunged straight at him.
Faced with the Ten-Thousand-Year Soul Beast's deadly charge, Qin Yun remained calm.
There was no panic in his expression. Instead, his eyes lit up.
He made his decision at once.
The Natural Uranium Crystal he had collected earlier had yet to see any use.
This was the perfect chance to test the power of its first-stage fission.
His mind made up, Qin Yun turned his wrist and quietly pinched a tiny fragment of Natural Uranium Crystal between his fingers.
The crystal was dull and looked utterly ordinary.
It seemed no different from a common pebble. It gave off no spiritual fluctuations or Soul Power.
In the next instant, Qin Yun activated his Periodic Table of Elements Martial Soul.
Pure Elemental Power quietly spread across his palm.
He precisely drew on the vast amount of hydrogen in the air.
He compressed, combined and catalyzed it at incredible speed, concentrating the hydrogen into a dense store of chemical energy ready to erupt.
He intended to use the instant force of a chain of hydrogen explosions to disrupt the crystal's unstable atomic structure and trigger the first stage of artificial Nuclear Fission.
Everything was ready.
With a flick of his wrist, Qin Yun tossed the tiny crystal fragment directly into the Blackflame Thunderstripe Tiger's path.
At the same time, he retreated as fast as he could.
The airborne tiger kept its eyes fixed on the human ahead.
It paid no attention to the inconspicuous fragment of crystal in midair.
As far as it knew, only Soul Power, soul skills or brute strength could hurt it. An ordinary pebble posed no threat.
It continued its savage lunge.
Then, in an instant, everything changed.
A faint, piercing hiss rang through the forest.
The highly compressed hydrogen detonated in a rapid chain, each chemical blast driving its force into the crystal.
The violent impact tore apart the crystal's stable structure.
The Uranium-238 was forced apart and broke down.
Fission began within a fraction of a second.
A blinding white light, brighter than the sun, burst forth and lit up the entire dark forest.
The temperature at the center of the blast shot up to thousands of degrees Celsius.
The surrounding air burned, while plants, stones and earth charred and vaporized.
Terror flashed across the once-ferocious tiger's face.
The searing heat curled and charred its tough fur. Agonizing heat and the pressure of imminent death engulfed it.
At last, it sensed the horror hidden in that unassuming crystal.
It twisted its massive body, desperately trying to pull away from the blast, but the fission reaction was far faster than its reflexes.
BOOM!
The entire forest shook. The ground cracked in layers, fissures racing outward in every direction.
A violent shockwave swept across the area, carrying scorching flames and a blast of high-pressure air.
Towering ancient trees snapped in half and shattered. Stones and earth flew everywhere.
Everything within a hundred meters became scorched wasteland in an instant.
Plants turned to ash. Soil and stone melted. Devastation filled the clearing.
At the center of the explosion, a churning, red-hot fireball swelled and rose. Its light shifted from brilliant white to crimson, then to a dark orange-black as billowing clouds piled upon one another.
At last, a small but ominous black mushroom cloud formed high in the sky.
It slowly rose and spread over the forest.
Eventually, the aftershocks faded and the dust settled. Silence returned to the woods.
Qin Yun walked forward and looked toward the center of the blast, shaken despite himself.
The fierce Ten-Thousand-Year Blackflame Thunderstripe Tiger had vanished completely.
Its massive body had been helpless against the full force of the fission reaction.
The heat had vaporized its flesh and bones, while the shockwave tore apart what remained. Not even an intact corpse was left.
Qin Yun now understood the power of the Uranium Crystal's first-stage fission.
It could kill a Ten-Thousand-Year Soul Beast instantly.
Such destructive power was enough to pose a mortal threat even to a Titled Douluo.
As he reflected on that, a blurred figure cut through the mist and sped toward him from the distance. Dugu Bo had returned.
Dugu Bo stared at the hundred-meter stretch of scorched earth, the shattered ancient trees and the cracked ground.
The air still carried an intense heat and a strange, unfamiliar aura of destruction.
This looked nothing like damage caused by a soul skill.
Dugu Bo swept a stunned gaze over the devastated scene, then turned to Qin Yun.
"Did... did you do this?" he blurted.
Qin Yun raised a hand and took out a small, dull fragment of Uranium Crystal.
His tone was casual.
"This did."
Dugu Bo's mind went blank. He had no idea what to say.
Qin Yun ignored his stunned silence and continued.
"I picked some medicinal herbs."
"When we get back, I'll start treating your granddaughter Dugu Yan's poisoning."
"You're not fooling me, are you? That tiny thing caused all this destruction?"
"Would you like to try it yourself, Senior?"
Dugu Bo stiffened and hastily waved his hands.
"No, no! We'd better get back and treat Yan'er!"
