"Even the Wan Yao Fan has lost ninety percent of its power."
The two of them looked up at the Ri Yue Zhong, which obscured the sky and blocked the sun. The sun, moon, and stars spun above it, seemingly repelling everything that did not belong to the Jiu Shan Realm.
The spiritual energy around them transformed once more into the tranquil state of bamboo before it fully grew. Sister Zhang could sense that, aside from the thunder techniques, other spells had lost their effectiveness in the Jiu Shan Realm.
"That Fusang wood..."
Sister Zhang's voice was low, her eyes burning with urgency.
Zheng Fa felt it too. The Fusang wood, which had once been exposed, was now suppressed by the Ri Yue Zhong, retreating into his body, seemingly losing its former power.
Yet at the same time, he felt a surge of strength within him... this power came from the Ri Yue Zhong!
The spiritual energy of the Jiu Shan Realm surged into Zheng Fa and the Tian Zun's bodies like a torrent through two conduits.
This spiritual energy carried a message that made Zheng Fa understand why the Tian Zun had appeared and why the Ri Yue Zhong had suddenly come to life:
Because the Tian Zun was, after all, a deity from the Upper Era, the master of thunder tribulations!
When Zheng Fa's cultivation triggered the heavenly thunder tribulation, it awakened the consciousness of the Tian Zun that lingered within the Ri Yue Zhong and the thunder tribulation.
At this moment, it was less about Zheng Fa facing the Yuanying tribulation and more about the ancient Dao Guo cultivator, the Tian Zun, suddenly reviving from the Ri Yue Zhong, eager to compete with the new master of the Jiu Shan Realm!
The five sects often spoke of ancient immortals reviving, but little did they expect that the first ancient immortal Zheng Fa encountered would be the very familiar Tian Zun.
The Ri Yue Zhong suppressed all treasures and spiritual plants that did not originally belong to the Jiu Shan Realm, yet it fairly distributed the spiritual energy to both Zheng Fa and the Tian Zun...
As if selecting the true master.
Zheng Fa soared into the air, aligning himself with the Tian Zun and the Ri Yue Zhong in a straight line.
The spiritual energy surrounding them was evenly matched.
However, above Zheng Fa's head, his golden elixir shone like the rising sun, illuminating half the sky with dazzling golden light.
In contrast, the stone tablet behind the Tian Zun was shrouded in dark energy, ancient and desolate.
The new and old masters of the Jiu Shan Realm, one bright and one dark, divided the sky in two.
This scene drew the attention of everyone in the Jiu Shan Realm.
On Le Tu Island, Xiao Qing stood in the classroom, staring blankly at the figure of the Tian Zun, murmuring:
"Lord Thunder God..."
The memory etched in her bloodline made the ordinary people of the Jiu Shan Realm instantly recognize the identity of the Tian Zun!
This was the Thunder God they had worshipped and revered for generations.
Xiao Qing looked at Zheng Fa, but her gaze was tinged with confusion.
That confusion quickly turned into worry.
Because the Tian Zun had made the first move!
With his fingers outstretched, a golden lightning bolt shot from his palm, aimed directly at Zheng Fa's face.
"Heavenly Tribulation Thunder!"
Sister Zhang, having studied Zheng Fa's thunder techniques, immediately recognized the origin of this thunder.
But the Heavenly Tribulation Thunder unleashed by the Tian Zun was a thousand times more powerful than anyone else's.
The lightning was blinding, and the heavens roared in fury.
The massive golden lightning caused the Nine Islands of the Heavenly Palace to tremble uncontrollably.
The Blood River Ancestor, being a soul body, was most afraid of the pure Yang thunder techniques. At this moment, his figure flickered, his face contorted in pain, as if he had suffered a great injury.
Sister Zhang glanced at him before turning her attention to Zheng Fa, who was directly in the path of the lightning.
If the Blood River Ancestor was already in such a state from not being struck, what about her junior brother?
But Zheng Fa was not in a panic. His Dong Xu Ling Yan was rapidly operating, capturing the trajectory of the spiritual power in the Tian Zun's palm.
Using the Heavenly Tribulation Thunder equation and a series of modern studies, Zheng Fa could even accurately estimate the potential energy and electromagnetic field fluctuations caused by this Heavenly Tribulation Thunder.
He traced his fingers in the air, and the spiritual power of the Ri Yue Zhong flowed along the path of his fingers.
In his hand, he conjured a robust Heavenly Tribulation Thunder.
He was actually competing with this ancient thunder path supreme!
The two bolts of Heavenly Tribulation Thunder collided violently in the air!
Everyone felt tense; the Tian Zun's Heavenly Tribulation Thunder was already earth-shattering, and with Zheng Fa adding fuel to the fire, how powerful would this thunder technique become?
But to everyone's surprise, the two seemingly opposing bolts of Heavenly Tribulation Thunder collided and formed a dazzling wave line, stable and silent.
"This..."
The Blood River Ancestor, forgetting his own injuries, suddenly looked up, staring blankly at the sky, utterly perplexed.
Not just him; the Tian Zun was equally baffled.
Though he had no face, his body remained still, facing Zheng Fa, appearing... somewhat at a loss.
At that moment, Zheng Fa surprisingly spoke up:
"I’ve taught you all the Heavenly Tribulation Thunder equations. Do you understand how to use them today?"
"When electromagnetic waves with the same frequency and amplitude but opposite directions meet, what happens? Have you figured it out?"
...
Uncle Huang, who was protecting the golden elixir disciples, had been a bit anxious, but now she found herself both amused and exasperated.
Are you still lecturing?
She turned to look at Yuan Xiaoniao and the other golden elixir disciples, noticing that a few of them had clearly attended the thunder technique classes and were now whispering among themselves, seemingly having gained some insights.
This is the Tian Zun!
A Dao Guo cultivator!
An ancient overlord!
Could you at least show him some respect?
But Zheng Fa's demeanor was remarkably relaxed—when the Ri Yue Zhong evenly balanced the spiritual power levels of both sides...
The Thunder Technique Supreme?
He was fighting against the Thunder Technique Supreme!
Under relatively fair conditions, Zheng Fa was confident that with the help of so many modern experts refining the thunder techniques, he would not lose to anyone.
Or rather, electromagnetism was precisely the field where modernity held the greatest advantage!
The Tian Zun seemed to grasp Zheng Fa's confidence as the thunder roared around him, appearing somewhat furious.
An enraged Tian Zun demonstrated to everyone why he could command the heavenly thunder tribulations!
Heavenly Tribulation Thunder.
Seasonal Thunder.
Even Cloud and Rain Thunder.
Various thunder techniques were wielded by him with divine mastery.
The Heavenly Tribulation Thunder, being the purest and most Yang, annihilated all life.
The Seasonal Thunder, in his hands, took on another role, seemingly disrupting the rhythms of the four seasons. Jiao Wuji, possessing the bloodline of a demon beast, felt it most acutely, as chaotic thoughts surged in his heart, making him feel as if he might lose control.
Cloud and Rain Thunder manipulated the weather, with raindrops and hail in the Tian Zun's hands acting like hidden weapons, striking towards Zheng Fa.
Not to mention other esoteric thunder techniques popular in the Xuan Wei Realm, which were executed with such finesse that they dazzled the eyes.
Yet Zheng Fa's responses left everyone in awe.
Whether he returned the techniques with their own or remained as steady as a mountain amidst the storm.
He continued to explain the key points of various thunder techniques.
Uncle Huang watched, feeling a mix of anger and disbelief—was the Tian Zun really being used as a teaching tool? Had he revived just to play along?
But she could see that the Tian Zun only wanted to fight, not cooperate.
Yet Zheng Fa's thunder techniques seemed almost divine, forcing the Tian Zun to cooperate.
She had to admit that Zheng Fa's actions had eased her own tension, but when she turned around, she saw several figures rushing past her towards the Zeng Xian Island, and she was taken aback:
"What are you doing?"
"We... we want to get a closer look."
Uncle Huang looked around and saw that these were the golden elixir disciples who had just been discussing. Clearly, they were quite adept at thunder techniques and now felt too far away to see clearly, wanting to move closer to hear Teacher Zheng's lecture.
Uncle Huang scolded, "What are you thinking? Are you trying to get yourselves killed?"
The disciples looked confused. "But... it doesn't seem that dangerous..."
"…"
Uncle Huang pursed her lips in resignation, having to admit that Zheng Fa had made some of the disciples a bit foolish... or rather, naive.
She scolded them back, then turned her gaze to the Tian Zun, feeling a strange sense of ease:
The Tian Zun, who had seemed so imposing moments ago, now appeared... rather harmless.
...
The Tian Zun could hardly tolerate such disregard, yet he found himself at a loss against Zheng Fa.
After a dozen exchanges, he suddenly halted, facing Zheng Fa.
A strange rumble of thunder echoed in his belly, forming a disjointed sentence: "You... thunder... techniques... are... strong..."
Zheng Fa frowned.
He certainly didn't think the Tian Zun was yielding to him.
"But... this... is... not... enough..."
"Not enough for what?" Zheng Fa couldn't help but ask.
"Not... enough... for... you... to... command... this... realm..."
Zheng Fa felt even more puzzled.
The Tian Zun then struck the Ri Yue Zhong with a palm, saying:
"I... am... this... realm..."
The thunder in his belly suddenly exploded into a fluent sentence:
"I am the Divine Dao Tian Zun!"
With this declaration, the Jiu Shan Realm suddenly underwent a tremendous change:
The classrooms transformed from the temples were turned upside down: the toppled statues rose into the air, their faceless forms unmistakably that of the Tian Zun!
