Under the gaze of the two Demon Empresses.
Jiang Fan, who had long mastered the cultivation technique, immediately began channeling enough Thunder Power.
He repeatedly attempted strikes towards the sky.
At first, he could only produce a thunder saber one zhang in length.
Then came two zhang, three zhang…
Finally.
After half a day, Jiang Fan swung vigorously at the clouds above him.
“Heavenly Thunder Six Parts: Undying Blade!”
Shhzz—
A war blade forged of thunder, spanning two hundred zhang, slashed across the heavens, splitting the clouds above into two halves!
The residual thunder arcs lingered in the sky, refusing to dissipate.
They emanated a searing aura.
In terms of power, it was several times stronger than the Five Thunder True Heaven Palm.
Within the two split fragments of cloud.
Each Demon Empress claimed one half of the cloud.
The South Sea Demon Empress had her eyes widened as she muttered in shock, “He… he mastered it just like that?”
“Isn’t it known that Earth-level High Techniques take at least years and at most decades to achieve mastery?”
“But he took just half a day?”
The East Sea Demon Empress was equally stunned.
“Half a day to master a technique that even old monsters might not grasp in years?”
“He… this son-in-law of mine, what is going on here?”
Under their astonished gaze.
Jiang Fan withdrew his Thunder Dao Divine Power and revealed a joyful expression.
“Undying Blade, First Layer, Great Success!”
“Unfortunately, I’m only allowed to train here for one day.”
“The time has already run out.”
Jiang Fan expressed some regret.
But he wasn’t too disappointed.
Smiling, he bent down and picked up the Heavenly Thunder Stone that had been soaking within the lightning pool beneath him.
This stone, forged by strikes of Heavenly Thunder, possessed the ability to converge lightning.
Having soaked for a full day now.
It had fully absorbed Thunder Power.
With enough time, he could use the stored thunder energy within it to cultivate the Second Layer!
His cultivation and techniques had progressed significantly.
Now there was only one thing left.
Seeing that the steward guarding the valley hadn’t urged him to leave yet.
He quickly took out two Infinite Rings.
One was intact, pure white as snow.
The other was shattered, exuding vibrant green hues.
“Since these rings are said to be the Yin Yang Double Rings, they should combine to exhibit a greater power.”
“In theory, their energy should be able to flow seamlessly.”
Jiang Fan pondered silently as he brought the two rings in contact.
To his surprise.
The fragmented green gemstone in the broken ring faded rapidly.
Conversely, specks of green visibly emerged on the intact ring.
Before long.
Both rings turned a light green hue.
Unable to pass energy any longer.
“The energy between the rings is like water between two rivers.”
“The higher water level flows to the lower level.”
