[Being struck by lightning was far from pleasant.]
[Surprisingly, however, Yu Xiaogang tolerated it rather well.]
[As the blue lightning entered his body, he clearly sensed that, besides possessing the basic properties of lightning, its primary target was his mind.]
[Fortunately, Yu Xiaogang's mental strength was exceptionally strong, and since his father had deliberately weakened the attack, the blue lightning caused little disturbance within his body.]
[At most, he merely experienced the numbness and shock of ordinary lightning.]
[After experiencing the effects of the blue lightning, Yu Xiaogang turned his attention to the golden lightning.]
[He reached out and guided it into his body.]
[This time, his entire body convulsed far more violently than before.]
[Unlike the blue lightning, which targeted the mind, the golden lightning focused almost entirely on the physical body.]
[Feeling the lightning surge wildly through every part of him, Yu Xiaogang quickly circulated his spirit power to neutralize its effects.]
[Once the lightning had been completely dispersed, he opened his eyes, smoothed down his hair that had been standing on end, and looked toward Yu Yuanzhen.]
«"The blue lightning attacks the mind, while the golden lightning attacks the body."»
[Yu Yuanzhen nodded with satisfaction.]
«"Exactly."»
«"That's precisely what the God of Destruction told me."»
[Hearing Yu Xiaogang's conclusion after only a single experience filled Yu Yuanzhen with pride.]
As expected of my son. He understood everything almost instantly.
«"The God of Destruction said that after consuming the Heavenly Treasure, the quality of my thunder attribute evolved."»
«"At the same time, it split into two perfectly balanced Yin and Yang aspects."»
«"One aspect combines with mental power to form Mental Thunder, which specializes in attacking the mind."»
«"The other combines with blood, vitality, and physical force to form Material Thunder, which specializes in attacking the physical body."»
«"When the two merge, they become the Thunder of Destruction."»
«"He also said that the path I'm walking resembles his own, which is why he offered me the chance to inherit the God of Destruction's Divine Position."»
[Yu Xiaogang nodded thoughtfully after hearing the explanation.]
Everything matched his earlier speculation.
The two types of lightning indeed targeted the mind and the body separately.
However, what truly surprised him was what happened after they fused together.
According to ordinary logic, combining a mental attack with a physical attack should simply create an attack capable of damaging both.
In Yu Xiaogang's understanding...
It should have been simple addition.
Three plus three equals six.
Yet reality proved otherwise.
After fusion, the two types of lightning transformed into a terrifying black lightning that seemed capable of destroying heaven and earth itself.
It wasn't addition.
It was multiplication.
If his expectation had been 3 + 3 = 6, then reality was closer to 3 × 3 = 9...
Or perhaps even greater.
This realization gave Yu Xiaogang an entirely new perspective.
Under the laws of the Douluo Continent, ordinary physical attacks and mental attacks might seem unremarkable on their own.
But once perfectly fused...
They underwent a qualitative transformation.
«"This is definitely worth researching."»
He suddenly recalled another concept.
«"Wouldn't this already fall under the category of a Self-Created Spirit Ability?"»
Yu Xiaogang had always known about Self-Created Spirit Abilities.
However, he had never devoted much time to researching them.
His schedule was already packed.
He needed to meditate to increase his spirit power.
He studied countless books every day.
He constantly trained to improve his combat experience.
It could be said that every moment of his day was fully occupied.
Besides...
There had never really been a need.
His First Spirit Ability possessed astonishing versatility.
In Yu Xiaogang's hands, it could already be used in countless different ways.
Combined with Little Dragon...
His Second and Third Spirit Abilities...
His combat methods were already abundant.
Because of this, he had never seriously considered researching Self-Created Spirit Abilities.
But today...
After witnessing his father's Thunder of Destruction...
His curiosity had been completely awakened.
If Mental Thunder and Material Thunder could combine to create the Thunder of Destruction...
Then what would happen if his own Light of Spirit and Light of Matter merged together?
The thought immediately ignited his research instincts.
Unable to suppress his excitement any longer, Yu Xiaogang briefly informed Yu Yuanzhen before immersing himself completely in experimentation.
Yu Yuanzhen could only shrug helplessly.
«"This brat..."»
«"The moment he gets an idea, he immediately starts researching."»
«"We've still got plenty of things to deal with here."»
Although he complained inwardly, he had no intention of disturbing his son.
Instead, he gestured toward Lin Lang and Dugu Bo.
The three quietly walked some distance away and began discussing other matters.
Meanwhile...
Yu Xiaogang was already completely absorbed in thought.
If he wanted to combine the Light of Spirit with the Light of Matter...
Where should he begin?
«"First..."»
«"I need to thoroughly understand both abilities individually."»
He took a small table from his storage soul tool, spread out paper and a pen, and began writing down his ideas.
«"According to the God of Destruction's explanation..."»
«"Father's Mental Thunder is formed by combining lightning with mental power."»
«"Its specialty is attacking the mind."»
«"In other words, it's thunder carrying mental force."»
He continued writing.
«"Following the same principle..."»
«"My Light of Spirit should become light carrying mental power."»
Thinking this through, Yu Xiaogang immediately identified the only spirit ability he possessed that directly affected the mind.
His Second Spirit Ability.
Without hesitation, he summoned his second soul ring.
Carefully circulating only a tiny amount of spirit power, he activated the ability at its weakest possible output.
Immediately...
A familiar energy gathered inside his throat.
Yu Xiaogang knew this feeling well.
His Second Spirit Ability always condensed there before being released as a powerful roar.
Previously, he had never questioned this process.
He simply activated it whenever necessary.
But this time...
He wasn't interested in using the skill normally.
Instead...
He wanted to isolate the mental-energy component contained within it.
Rather than releasing the technique, he attempted to guide that condensed energy away from his throat.
Unfortunately...
No matter how hard he tried...
The energy refused to move.
It remained firmly fixed in place.
Not even the slightest shift occurred.
Yu Xiaogang frowned.
«"So this..."»
«"Is the first challenge of creating a Self-Created Spirit Ability."»
«"I need to dismantle a spirit ability whose structure has already been completely fixed."»
«"Then separate the specific component I need from the complete technique."»
He pondered the problem carefully.
It was like a kitchen staff.
One chef washed the vegetables.
Another chopped them.
A third handled the cooking.
Together, they formed one complete team.
But now...
He only needed the chef responsible for chopping vegetables.
To achieve that...
He first had to separate that individual from the team...
And make him work independently under his own command.
