**Chapter 314: Clear Transmission, Life-Bound Treasure**
Zheng Fa stood side by side with the Remnant Sun Sword Immortal, gazing ahead. The members of the Jiu Shan Sect, along with Xiao Yu Ying and Madam Xuan Hua, gathered nearby, their expressions tense and silent.
The atmosphere was thick with anticipation, broken only by the gleam of silver light in Uncle Pang's eyes, his face betraying a single thought—my eyes are my measure!
This was a race between Zheng Fa and the Remnant Sun Sword Immortal. It was the latter who had suggested testing the "Transformation into Rainbow" technique after hearing Zheng Fa's claim of it being the fastest.
To ensure fairness, they chose a location outside the Jiu Shan Realm, deep within the Xuan Wei.
"That mountain will be the finish line. Go!" Uncle Pang commanded, pointing to a distant green peak.
The Remnant Sun Sword Immortal remained still, his life-bound flying sword enveloping him in a flash of light, disappearing in the blink of an eye.
Madam Xuan Hua sighed, "The Tian He Sect's sword evasion technique is renowned as the best in the world; it's truly impressive."
The others nodded in agreement, even Xiao Yu Ying, usually so proud, admitted, "The Tian He Sect is indeed unparalleled in swordsmanship... Not to mention, the Remnant Sun Sword Immortal is no ordinary Yuan Ying."
Her words carried weight, especially coming from someone with such high standards. After all, the Remnant Sun Sword Immortal was a figure who lingered at the threshold of the Transformation stage, refusing to step inside.
In just a breath, the Remnant Sun Sword Immortal's sword light reached the green mountain. He wasn't concerned about winning; he merely wanted to witness the power of Zheng Fa's innate ability. After all, even their own ancestor seemed to possess only one such talent.
How could Zheng Fa have another? It made it seem almost trivial!
To sum up his worries: if this continued, the value of their ancestor's legacy would diminish!
Lost in these chaotic thoughts, he looked up to find someone standing at the mountain's peak, smiling down at him.
It was Zheng Fa, standing there with his clothes perfectly in place, gazing down with an air of leisure, as if he had been waiting for quite some time...
When did Zheng Fa arrive?
"You..."
"Just landed," Zheng Fa replied with a thoughtful smile.
Ah, he can't even lie properly!
The Remnant Sun Sword Immortal blinked at Zheng Fa, feeling a mix of consolation and frustration.
Consolation came from the realization that this innate ability was indeed powerful... Their ancestor was still formidable!
Frustration stemmed from the feeling of inadequacy... Zheng Fa was merely at the Golden Core stage!
...
Back in the Jiu Shan Realm, with only Sister Zhang and their master around, Zheng Fa began to analyze the pros and cons of the Transformation into Rainbow technique.
"After comparing with Old Han, I've concluded that this technique... is all about speed!" Zheng Fa explained.
Everyone's faces lit up with surprise; it sounded like this technique was indeed a great power!
Zheng Fa felt that it was even stronger than he had imagined. The speed of light is the maximum speed for information transfer in the universe—only photons, lacking rest mass, can reach that speed.
But the Xuan Wei Realm was different; the variable of spiritual energy greatly affected electromagnetic waves, even altering the speed of light...
The flaw of the Transformation into Rainbow technique was that it didn't correspond to the constant speed of light but rather to the maximum speed achievable in that specific environment.
In simpler terms, during a competition, no matter where you are or how fast you are, you will never exceed my maximum speed!
"Isn't that like being able to go wherever you want? Attack whoever you want? Steal whatever you want?" Sister Yuan's eyes widened with envy as she looked up at the sky, seemingly wishing for the heavens to grant her an innate ability.
...Sister, is that all you aspire to?
"Not quite," Zheng Fa shook his head. "Like the Five Element Divine Light, this technique is limited by my cultivation level."
"…Time?" Sister Zhang realized.
"Exactly. With the Transformation into Rainbow technique, I can only maintain it for the duration of an incense stick before my spiritual energy runs out," Zheng Fa admitted.
If he were in front of others, he would never have revealed this...
"And if I weren't the master of the Jiu Shan Realm, I wouldn't be able to fly out of it with this technique."
Everyone nodded, understanding Zheng Fa's point—if someone trapped him in an environment like the Jiu Shan Realm or used a similar technique, then... no matter how fast he was, it would be futile.
Uncle Pang's eyes brightened as he asked, "Can you take the Jiu Shan Realm with you?"
"I can," Zheng Fa nodded, "but... only for a moment."
"…A moment?"
"After that moment, I would be completely drained..."
The joy on Uncle Pang's face faded; Zheng Fa's meaning was clear—he could carry external objects, but the cost to his cultivation would be significant.
He could already envision the scene Zheng Fa described:
In that moment, no one could catch up to him. But after that moment, Zheng Fa would be kneeling before them, and they wouldn't be able to catch him even then!
Even Sister Yuan understood now; she nodded seriously and summarized succinctly, "Zheng Shidi, fast but short-lived!"
...That bird's mouth, becoming a streamer, sounds like it's been poisoned!
Old Master Yuan chuckled, "Putting everything aside, Zheng Fa likely has no worries about his life when facing Yuan Ying or even Transformation stage cultivators!"
With that, smiles spread across the faces of the others.
Zheng Fa was the foundation of the Jiu Shan Realm; the safer he was, the more at ease they felt.
"I guess I'm just being greedy," Uncle Pang laughed, looking at Zheng Fa. "Now that you've formed your Golden Core, have you thought about your life-bound treasure?"
"I need to start looking for materials for my life-bound treasure... It took me many years to gather the materials for the Five Dragon Heavenly Palace."
"Now, with fewer spiritual materials in the Xuan Wei Realm, it might be even more troublesome."
"If you have any ideas, we should plan early to avoid delays later."
The others turned their serious gazes toward Zheng Fa, clearly understanding the importance of the matter.
Zheng Fa felt warmth in his heart; indeed—after forming the Golden Core, it was time to prioritize his life-bound treasure.
But...
"I'm still not sure..."
Old Master Yuan stroked his beard, frowning. "In the 'Divine Sky Thunder Control Technique,' there are three types of life-bound treasures to choose from, all of which are quite powerful."
"For instance, my Zhou Tian Bagua Array Disk focuses on controlling thunder, greatly aiding in setting up thunder arrays."
"Then there's the Zixiao Demon-Slaying Sword, which merges myriad thunders into one sword, embodying the utmost Yang and strength—it's the most popular choice."
"Lastly, there's the Zhen Tian Drum, a method I acquired in my youth, rumored to possess some unique abilities..."
As Zheng Fa listened, he nodded in agreement.
The 'Divine Sky Thunder Control Technique' is indeed the highest transmission of the Jiu Shan Sect, and the three treasures within it are certainly impressive.
At the very least, there are no shortages of secret techniques for those who reach the Yuan Ying stage.
As for what Master mentioned—a sword, a drum, and an array disk—each has its own wonders and has stood the test of time.
Choosing the array disk would allow him to rely on Master for guidance, and besides, it packs quite a punch.
The Demon-Slaying Sword is the choice of most practitioners of the 'Divine Sky Thunder Control Technique,' powerful and compatible with swordsmanship.
