Chapter 209: Chapter 106 Equations (4K)

Zheng Fa walked into the room, where Old Man Bai and Tang Lingwu were both busy.

Tang Lingwu was processing data collected from various sensors on the computer, including the magnitude of electric currents, the intensity of voltages, temperature, and the shape and color of lightning captured by high-speed cameras.

Old Man Bai was examining various patterns on paper, trying to find the key among them.

Zheng Fa first walked over and sat down next to Old Man Bai, feeling tired for the first time in a long while.

The Thunder Skill in the Heavenly Stele Realm was somewhat peculiar: the power of Heavenly Tribulation Thunder was far greater than that of ordinary Thunder Skills, but on the other hand, the requirements for cultivation were relatively low.

Like Zheng Fa, who was only at the Foundation Establishment Stage, had just released nearly eight or nine bursts of Heavenly Tribulation Thunder. Had he not wanted to reserve some Spiritual Power for the "Spirit Mountain Technique", he probably could have done it a couple more times.

But he hadn’t felt it before, only now did he feel a sharp pain in his head, most noticeably at his temples—it felt as if someone was drilling a tunnel right through his head.

He sat at the table, pinching his temples, recalling a similar situation recorded in the Jiushan Sect’s scriptures—this was a sign of slight damage after excessive consumption of Divine Soul.

This was rare for him; compared to his early Foundation Establishment cultivation, his Divine Sense was even stronger than that of late Foundation Establishment.

Normally, his Spiritual Power should have been exhausted before his Divine Soul.

This made him speculate: perhaps the excessively strong power of Heavenly Tribulation Thunder stemmed from the excessive consumption of a Cultivator’s Divine Soul.

"Zheng Fa, what’s wrong?"

Old Man Bai’s gaze, originally fixed on the drafts in front of him, shifted to Zheng Fa when he noticed something was amiss and saw his pale face, prompting him to ask.

"It’s nothing, just an over-exertion of Divine Sense; more rest in the coming days will help," Zheng Fa shook his head, "Have you discovered anything?"

Heavenly Tribulation Thunder was considered the most basic Thunder Skill in Heavenly Stele Thunder Skills.

But people like Yan Wushuang still hadn’t mastered it mainly for two reasons:

Firstly, no one knew exactly how Heavenly Tribulation Thunder was generated.

That is, among so many patterns, which one could be the talismanic diagram of Heavenly Tribulation Thunder.

Without understanding this, naturally, the second problem arose: how to control the strength of Heavenly Tribulation Thunder.

At this moment, Old Man Bai was trying to investigate the first point; the approach was actually quite simple: whenever Zheng Fa successfully deployed Heavenly Tribulation Thunder, they would collect those Spiritual Power trajectories and then use Topology to identify common patterns within those trajectories:

This approach was exactly like researching the talismanic Dao.

But for Cultivators in the Xuanwei Realm who had not been trained in Topology, these trajectories might not have any similarities...

"Ah, this is simple," Old Man Bai pointed at the drafts on the table: "These patterns always appear, just the number of occurrences each time differs."

Zheng Fa looked and nodded, "If we add the Five Elements Child Talisman, this might just be the Spirit Talisman of Heavenly Tribulation Thunder."

According to the Three Child Talismans theory he and Old Man Bai had speculated, if a Spell is regarded as another form of expression of a Spirit Talisman, then the Spiritual Power itself could provide the Five Elements Child Talisman, and these operating trajectories should correspond to the second and third type of Sub-talisman.

"That’s right... unfortunately, we have not discovered any common Sub-talismans between this Heavenly Tribulation Thunder pattern and other Thunder Skill Spirit Talismans." Old Man Bai had looked back and forth, because of this: "If Tang Lingwu’s conjecture about interactive Sub-talismans is true, then Thunder Skills... should have exactly the same Sub-talismans."

Zheng Fa also pondered upon hearing this.

Their research on Thunder Skills was actually due to the relatively simple target of these Spells, whether the essence of Thunder Skills was the effect on electrons or electromagnetic fields... it should have the same target, meaning there should be a common Sub-talisman.

Yet...

That wasn’t the case.

This had given them a feeling of groping in the dark like blind men feeling an elephant, and every time they felt a different part.

...

"Done!" Just as they were discussing, Tang Lingwu exclaimed, and both turned their heads to see the computer screen displaying various lightning images, each in different colors and lengths.

Beside it were some fluctuating curves.

Showcasing the current, voltage, and temperature formed on the metal column by each lightning strike.

Zheng Fa and Old Man Bai walked over to look at the various data on the screen.

"Is there any pattern?" Old Man Bai asked.

"Nothing special, except for the correspondence between current and voltage, temperature, and the color of lightning,"

Zheng Fa nodded, these correspondences were already somewhat understood in physics.

"Take a look at this?" Old Man Bai handed over an analyzed pattern, Tang Lingwu looked at it, furrowed her brows as if she remembered something, and started quickly operating on the keyboard, too engrossed to mind Zheng Fa and the others.

Zheng Fa exchanged glances with Old Man Bai, walked forward, and watched the computer screen.

"Is this... fitting?"

After watching for a while, Zheng Fa understood that Tang Lingwu was fitting these identical patterns’ occurrences with various data, trying to find a pattern.

These data were not complex, even simply put.

The computer quickly displayed an equation.

Old Man Bai looked perplexed but concluded directly: "The intensity of the current is roughly proportional to the sixth power of these occurrences?"

Zheng Fa was also surprised, the fitted outcome was really simple, a mere straightforward sixth power equation, excluding those coefficients, the variable X in the equation was the occurrence times of those patterns, and the other side of the equation was the peak of the current.
