After noticing that Yu Tianheng had only one Soul Ring,
Yu Yuanzhen couldn't help reaching out and patting Yu Yuanzhen on the shoulder.
"Of course Grandpa will keep his promise to you, but before that, you need to see the gift I prepared for you."
"A gift?"
With Yu Tianheng wondering what it was, the old man and the boy came to the place where the Blue Lightning Tyrant Dragon Clan kept its captive Soul Beasts.
"Grandpa picked this one out especially for you: a seven-hundred-year-old Extreme Ice Dragon Python."
Yu Yuanzhen had picked it out especially for Yu Tianheng during this time.
It was a good match for Yu Tianheng's Martial Soul in every respect.
But who would have thought that Yu Tianheng would shake his head at the sight of it?
"Grandpa, I want to try a stronger Soul Beast."
When he had absorbed his First Soul Ring, Yu Tianheng had clearly felt it.
Four hundred and twenty-three years might have been the limit for a normal Soul Master.
But his Martial Soul was different to begin with. Even across the entire continent today,
there might not have been another Martial Soul that could compare to it.
That shouldn't have been his limit.
Otherwise, absorbing the Soul Ring would never have been so easy.
For his Second Soul Ring, Yu Tianheng intended to push the age limit higher.
"Oh? Then how old a Soul Ring are you planning to absorb?"
Yu Yuanzhen asked after pondering for a moment.
He had to help Yu Tianheng judge this matter carefully.
The consequences of absorbing a Soul Ring beyond one's limit were unthinkable.
"Nine hundred years, I think. Absorbing a Thousand-Year Soul Ring is probably still impossible for me right now."
Yu Tianheng stated his thoughts plainly.
For a normal Soul Master, the limit for a Second Soul Ring was 764 years.
But the exact limit varied from person to person.
Yu Yuanzhen said nothing for a long time after hearing him.
He seemed to be considering whether it was really possible.
Seeing his grandfather's brows tightly knitted, Yu Tianheng spoke again.
"Don't worry, Grandpa, I know what I'm doing. The fact that I reached level twenty in such a short time is enough to prove that my Martial Soul is different. If I absorb a Soul Ring with a low age, I'm afraid it'll affect my strength in the future."
He wasn't trying to sound alarmist.
Soul Rings were what determined the upper limit of a Soul Master's strength.
After an unknown length of time, Yu Yuanzhen slowly nodded.
"Since you've put it that way, Grandpa will let you make your own decision this once. But you must concentrate fully at the very beginning. If anything goes wrong, tell Grandpa immediately. I'll find a way to help you at once."
All Yu Yuanzhen could do was step in and interrupt Yu Tianheng at the very start of the absorption.
There was no historical record of such a situation.
Whether it would succeed was also unknown.
Without realizing it, Yu Yuanzhen had been drawn into Yu Tianheng's reasoning.
After all, his grandson had given him far too many shocks since his Martial Soul Awakening.
Otherwise, given his usual character, he would never have agreed.
After the two looked over their choices, Yu Tianheng finally set his sights on a nine-hundred-and-ninety-nine-year-old Blue Lightning Tyrant Dragon.
It was a captive Soul Beast unique to the Blue Lightning Tyrant Dragon Clan.
It had originally been kept for a future heaven's chosen to absorb.
Aside from its slightly advanced age, it was a perfect match for Yu Tianheng.
"Grandpa, let's go with this one."
"Are you sure?"
Yu Yuanzhen asked one last time.
"Yes. If you don't enter the tiger's den, how can you catch its cub?"
As soon as he finished speaking, Yu Yuanzhen raised his hand without hesitation and unleashed a terrifying bolt of lightning.
The power of a Titled Douluo left the Blue Lightning Tyrant Dragon, which was on the verge of becoming a thousand-year Soul Beast, barely clinging to life.
Yu Tianheng wasted no time either. He used Martial Soul Possession, and with the enhancement of his first Soul Skill,
his dragon claw slammed squarely into the Blue Lightning Tyrant Dragon's massive head.
One strike killed it, cleanly and without a wasted movement.
A Yellow Soul Ring gradually rose from the corpse.
Yu Tianheng raised his hand and released his Soul Power, drawing the Soul Ring toward him.
"Come on, let me see whether you can become my Second Soul Ring."
Not far away, Yu Yuanzhen watched Yu Tianheng's every move with a grave expression, his eyes fixed on him.
He was even beginning to regret agreeing to Yu Tianheng's decision.
But to his surprise, nothing unusual happened to Yu Tianheng.
He entered the state of absorbing the Soul Ring without the slightest difficulty.
The enormous phantom of the Thunder Dragon King appeared behind him.
If it had been another Soul Ring of this age, Yu Tianheng would probably have had considerable difficulty absorbing it.
But the Thunder Dragon King simply suppressed the Blue Lightning Tyrant Dragon through the superiority of its rank.
There was no backlash of Soul Power or anything of the sort.
Compared with absorbing his First Soul Ring, it merely took a little longer.
Not only that, but even Yu Tianheng himself failed to notice
that his Thunder God Domain had been released without anyone realizing it.
Streaks of purple lightning, each like a giant python, struck the Soul Ring head-on.
Purple lightning covered the Yellow Soul Ring, making it impossible to see clearly.
More than ten minutes later, the Soul Ring gradually merged into Yu Tianheng's body.
The next moment, Yu Tianheng's eyes snapped open.
Arcs of electricity seemed to flicker in his eyes.
"Grandpa, I did it."
Yu Tianheng slowly stood up and spoke in his grandfather's direction.
Seeing this, Yu Yuanzhen's heart, which had been hanging in suspense, finally settled. He wiped the cold sweat from his forehead and asked,
"Heng'er, what is your second Soul Skill?"
Yu Tianheng murmured,
"Second Soul Skill, Blue Lightning Tyrant Transformation!"
Two Soul Rings, one yellow and one purple, slowly appeared.
Yu Tianheng's eight-year-old body gradually began to swell.
He now looked no different from a boy of thirteen or fourteen.
Lightning surged around him, and his eyes changed from black to blue.
His brow and eyes were filled with killing intent.
His presence kept climbing, as though it could sever everything in time itself.
Once activated, Blue Lightning Tyrant Transformation increased all attributes by 150%. While it was active, absorbing lightning could heal injuries and restore his Soul Power.
It was a perfect match for Yu Tianheng's Thunder God Domain.
"Purple? A Thousand-Year Soul Ring?"
Yu Yuanzhen could hardly believe his eyes.
He had clearly checked just now and confirmed that the Blue Lightning Tyrant Dragon was only nine hundred and ninety-nine years old.
Seeing his grandfather's confusion, Yu Tianheng hurried to explain.
"Grandpa, while I was absorbing the Soul Ring, my Martial Soul kept releasing lightning to temper it. Maybe that helped the Soul Ring break through that final barrier."
The truth was more or less what Yu Yuanzhen had said, but he did not tell his grandfather directly about the Thunder God Domain.
A Martial Soul that came with a domain upon awakening was simply too world-shaking.
No normal person would likely believe it.
After a moment of astonishment, Yu Yuanzhen threw back his head and laughed.
"Good! Good! Good! A son of my Blue Lightning Tyrant Dragon Clan has a Thousand-Year Soul Ring as his second Soul Ring! From ancient times to the present, has anyone else ever managed such a thing?"
"Heaven truly favors our Blue Lightning Tyrant Dragon!"
In just two sentences, Yu Yuanzhen had given full vent to the frustration pent up in his heart.
The Blue Lightning Tyrant Dragon would surely become the number one sect on the continent in the future!
