At those words, a cold gleam flashed through Dugu Bo's eyes.
The Ice and Fire Yin Yang Well was a deadly poison in this world. He had lived here for so many years, yet had never once considered entering its waters.
Had Yu Tianheng actually gone straight in?
"Let's go!"
Dugu Bo felt his heart clench. If anything happened to Yu Tianheng here, he could never bear the responsibility!
The two came to the edge of the spring, only to find its surface perfectly still, as though nothing had happened.
Dugu Bo immediately released his Soul Power and began probing the lake.
He could only hope Yu Tianheng was still alive.
"Grandpa, how is it? Is Tian Heng all right?"
When her grandfather said nothing for a long while, Dugu Yan grew so anxious that she burst into tears.
She kept shaking Dugu Bo's arm, hoping her grandfather could bring Yu Tianheng back.
In her eyes, her grandfather was capable of anything.
After a long while, Dugu Bo's brows were nearly knotted into the character for "river."
"How strange. There is indeed a presence in the Ice and Fire Yin Yang Well that matches Tian Heng's extremely closely, but he doesn't seem to be coming up. Instead, he's heading deeper into the spring."
Hearing that Yu Tianheng was all right, Dugu Yan relaxed and nearly collapsed to the ground.
She kept murmuring to herself.
"As long as he's all right. Tian Heng must have his own plans."
And so the two waited beside the Ice and Fire Yin Yang Well for Yu Tianheng to come up.
At the bottom of the spring, after tempering his body with three supreme-grade spirit herbs and the Ice and Fire Yin Yang Well,
Yu Tianheng was largely unaffected by the water.
He had no idea how long he had spent channeling his Soul Power and swimming down.
At last, he could make out the bottom of the spring.
Yu Tianheng released his Martial Soul, using lightning to illuminate his surroundings.
In that instant, he felt as though his breathing had stopped.
The space at the bottom of the Ice and Fire Yin Yang Well was enormous, large enough to encompass more than half the Sunset Forest.
Within it lay the corpses of two colossal dragons, arranged head to tail.
One was red and the other blue. They were undoubtedly the Fire Dragon King and the Water Dragon King.
The sight was so breathtaking that it was almost beyond words.
Yu Tianheng landed on his feet and reached out to touch the Fire Dragon King's skeleton.
But as he drew closer, the temperature continued to rise.
It nearly broke through the Soul Power barrier around his body.
"Come, become my second and third Martial Souls!"
Yu Tianheng sat cross-legged and began using the secret method he remembered from later generations for summoning the two Dragon Kings' dragon souls.
Gradually, two streams of Qi emerged from Yu Tianheng's fingertips.
The streams of Qi attached themselves to the remains of the two Dragon Kings and slowly began to change color.
One turned crimson, the other icy blue.
After an unknown length of time, two enormous dragon souls appeared.
In an instant, the plants on the banks of the Ice and Fire Yin Yang Well began growing wildly at a speed visible to the naked eye.
The commotion gave even Dugu Bo, who had reached the Titled Douluo realm, a fright.
He could clearly sense that two terrifying presences had appeared at the bottom of the spring at some unknown point.
Before those presences, he felt as insignificant as an ant.
He was utterly incapable of fighting back.
He hurriedly scooped up the sleeping Dugu Yan and kept retreating.
Yu Tianheng also sensed the two dragon souls eyeing him like tigers stalking their prey.
It seemed they would attack him the next second.
Martial Soul Possession! Thunder God Domain, release!
Two purple Soul Rings appeared beneath Yu Tianheng's feet.
Behind him, the enormous phantom of the Thunder Dragon King faced off against the two dragon souls across the distance.
The two dragon souls froze at the sight of the Thunder Dragon King.
Why did this presence seem to be on the same level as theirs?
There was even a faint sense of suppression.
"The old kings are dead; a new king must rise! Why not lend me your aid?"
As his words fell, two chains seemed to emerge from Yu Tianheng's body.
They bound the dragon souls of the two Dragon Kings tightly.
Then they began dragging the souls toward Yu Tianheng.
The power granted by the system was, after all, something that transcended planes.
Even the dragon souls of the two Dragon Kings could not resist it.
After struggling for a moment, the two dragon souls seemed to come to an understanding.
They actually let the chains control them.
The Thunder Dragon King, the sense of suppression, and the suppressive force of the chains.
Every one of these factors struck at the two Dragon Kings, who had fallen an unknown number of years ago.
As the dragon souls entered his body, Yu Tianheng felt as though he were being torn apart.
One cold and one hot, the two extremes were countless times more intense than when he had taken the Infernal Delicate Apricot and Octagonal Mysterious Ice Grass.
Even his blood, meridians, and bones seemed to be steadily affected by the two extremes.
Yu Tianheng gritted his teeth and fought desperately to stay conscious.
Absorbing dragon souls of his own accord was something no one had done before and no one would do again.
He could not be sure whether, if he fell asleep like this, the two Dragon Kings would use his body to come back to life.
He absolutely could not afford the slightest carelessness in this matter!
"Grandpa, it's already been half a month. Why hasn't Tian Heng come out yet?"
Because of the terrifying presences last time, Dugu Bo absolutely refused to let Dugu Yan wait around the Ice and Fire Yin Yang Well all day.
She could only do so when he accompanied her, and when she was awake and alert.
For that reason, as soon as Dugu Yan woke up each day, she would pester him to take her to the Ice and Fire Yin Yang Well.
Hearing his granddaughter's words, Dugu Bo remained silent for a long time.
During this period, he had released his Soul Power to probe the spring every day.
As time passed, the two unusually tyrannical presences at the bottom of the spring
seemed to be gradually weakening.
Yu Tianheng's presence had even grown stronger.
Just what was this kid capable of, to coexist with beings like that for so long and even grow stronger?
Yu Tianheng, who had been silent for half a month, suddenly opened his eyes.
A red light and a blue light flashed through them.
Yu Tianheng could feel that his bones, meridians, and the surfaces of his internal organs were coated in a crystalline substance of interwoven blue, red, purple, and blue.
His blood was also completely different from before, with three kinds of Qi faintly intertwined within it.
At a thought, a blue light and a red light flew from the center of his brow.
They landed in Yu Tianheng's hands, one in each.
The red light in his right hand gradually condensed into a three-foot sword, blood-red all over, with black patterns running its entire length.
But the sword's edge was damaged.
Two small characters were engraved on the hilt in an obscure script.
"Ember Dust."
The blue light in his left hand spread out like a flower in bloom.
When the light faded, only a rose made entirely of ice remained.
A quarter of the rose's petals and leaves were missing, leaving an irregular gap.
Without a doubt, these were the weapons of the Fire Dragon King and the Water Dragon King.
The Ember Dust Sword and the Ice Seal Rose.
But both divine weapons were damaged.
Yu Tianheng raised his hands and returned the two divine weapons to the center of his brow.
"Even damaged, in this day and age, they would still stand absolutely above all others."
