The unit of potential difference is J/C, and this unit has a separate name: volt.
The work required to move 1C of charge through a potential difference of 1V is 1J. In the Gaussian system of units, it is erg/esu and is called a statvolt. 1C equals 3×10^9 esu, and using this relationship, one could prove that 1V was approximately equal to 1/300 statvolt.
Baili Qingfeng flipped through the book.
Although the harm caused by a tiny amount of current was nothing to him—he would not die from it anyway.
But...
Out of responsibility toward his family, he still had to be more careful.
What if he traveled through time again and ended up in an ancient environment with no books to read and no schooling to attend? Life would become utterly dull.
The safe voltage for the human body was thirty-six volts, the safe current ten milliamperes, and the resistance five thousand ohms.
Baili Qingfeng pinched the end of the wire and visualized the Thunder Sovereign Spirit Refinement Visualization Method. He guided his breathing with his spirit, then used his breathing to follow the Thunder Breath diagram as he adjusted his own electric potential ever so slightly.
Watching the needle on the electroscope change, he nodded in satisfaction.
It worked!
The only drawback was...
It was not very sensitive. He needed to practice more.
"Let's take it one step at a time. My progress in Rushing Thunder Thirty-Six Forms and the Thunder Sovereign Visualization Method has been highly significant, but my progress in Thunder Breath, this breathing technique, has been less than satisfactory. I need to put in more effort, but... the key is still to cultivate the sixth level of Thunder Sovereign as soon as possible."
The description of the sixth level of Thunder Sovereign flashed through Baili Qingfeng's mind.
Upon reaching this level, a cultivator's spirit would become powerful enough to influence their own evolution in reverse. Once this influence reached its extreme, it could even penetrate down to the cellular level.
Human cells possessed a complete cell membrane, divided into inner and outer layers.
Under normal circumstances, there were more potassium ions inside the cell, while the solution outside the cell contained more sodium ions. A potential difference formed between the inside and outside of the cell, creating a membrane potential. Once the ion channels in the cell membrane opened, the high-concentration solution outside the cell flowed inward, producing an action potential. The cells lined up in neat rows and were then linked together by nerves, resembling sections of miniature batteries connected together. Although each battery contained an extremely tiny amount of electricity, when the number of these miniature batteries reached hundreds of millions—even billions—the amount of electricity they unleashed would be astonishing.
If the Thunder Sovereign Visualization Method could be said to alter a person's potential difference in broad terms and change the voltage of the human body, then the Evolving realm could operate precisely on every basic cellular unit. It could even produce subtle changes in cellular structure, causing the cells to evolve toward the legendary creature, the Thunder Beast.
"Charge is the foundation, but to release the charge carried on the body, the key lies in voltage and resistance. Resistance in the outside world varies too greatly with environmental conditions. Dryness and humidity can differ by more than a hundredfold. To break down the air, the voltage has to reach thirty thousand volts, but with a superconductor to guide it, things become much easier..."
Baili Qingfeng suddenly thought of the later stages of the Thunder Sovereign Visualization Method.
At those stages, a cultivator's spirit would evolve into a special existence midway between reality and illusion. It could interfere with the outside world like a spiritual field. By then, he might be able to use his spiritual field to carry an electric current, then twist the potential difference to its extreme, forming an astonishing voltage and releasing all the charge carried on his body in one breath, transforming it into a violent electrical surge.
Of course, this was merely the most basic skill of Thunder Sovereign.
Telepathy, electromagnetic induction, electromagnetic resonance, electromagnetic coil cannons, and electromagnetic levitation were the advanced applications of Thunder Sovereign.
Mind reading, detection, Lion's Roar Technique, sword control, walking through the air...
Just thinking about them made him look forward to it.
"For the current me, the most important thing is to cultivate Rushing Thunder Thirty-Six Forms and strengthen my physique. But in the long term, the Thunder Sovereign Visualization Method is the true path."
Baili Qingfeng pondered briefly and nodded slightly.
Perhaps because two souls had merged, he possessed an innate advantage in cultivating the Thunder Sovereign Spirit Refinement Visualization Method. Although saying that one day of cultivation for him was equivalent to a hundred days for others was somewhat exaggerated...
But...
Ninety-some days was still possible.
At the very least, it would not be less than eighty days.
That was also why he had been able to cultivate the Thunder Sovereign Spirit Refinement Visualization Method to the Fifth Stage Manifestation in just over a month.
Since he had talent in this area...
What was he waiting for? Practice.
Once his Spirit Refining Method advanced, it would naturally be able to boost his breathing technique and Body Refining Technique as well.
With that thought, Baili Qingfeng temporarily overturned his previous cultivation plan and formulated a new one centered on Spirit Refining, supplemented by body refinement, with the breathing technique... dependent on his mood.
Sharpening the knife did not delay chopping wood!
He had already resolved to cultivate properly... and read properly, so...
To give himself a better learning environment, a better mood for studying, and a more positive attitude toward learning, spending four hundred thousand to buy the Small Courtyard was not excessive.
After all, it was for the sake of studying.
Besides...
The body was the capital of revolution.
If he wanted to read and study properly, he needed a healthy body. Thus, he spent another several hundred thousand to buy batches of Nourishing Essence Soup ingredients from Ran Tianchi, nourishing his physique.
Under such circumstances, the study expenses compensated to him by the Jiang brothers did not last very long. Before long, he had spent nearly all of it, leaving only a hundred or two hundred thousand.
Time flew by, and two months had passed.
During those two months, Xia'er City had rarely fallen into a period of peace. Although social incidents still occasionally stirred up ripples, their overall impact was minor. At the university, Baili Qingfeng easily enjoyed the life an Outstanding Student ought to have: reading, attending classes, practicing martial arts, listening to music, and occasionally returning home to see his family.
Peaceful and tranquil.
In two months, Baili Qingfeng's academic performance had not only ranked among the best, his martial cultivation had also improved significantly.
He practiced Rushing Thunder Thirty-Six Forms without the slightest pressure now. Going through it five or six times in ten minutes was as easy as playing around.
That day, after class, Baili Qingfeng continued deeper into Xia'er City and arrived at the clubhouse where Ran Tianchi, Wang Zheng, Morpheus, Jack, and the others were staying.
However, when he arrived at the clubhouse, he found it unusually lively. Not only were Ran Tianchi and the others there, but more than a dozen members who rarely came had also shown up. Among them were several middle-aged men who were clearly the elders of Ran Tianchi and the others at a glance.
Baili Qingfeng paid them no attention. After nodding at Ran Tianchi, who followed behind those people like a lackey, he went straight toward his training room.
As the only Master in the clubhouse, his training room was quite spacious, with every kind of training equipment available.
Baili Qingfeng picked up a sword and began practicing just like that.
Recently, he had discovered that Rushing Thunder Thirty-Six Forms was gradually becoming less effective at tempering his body. Although it still worked, the improvement was no longer as obvious as before. During this period, he had constantly browsed the Sword Rain World forums and found three other Body Refining Techniques. He planned to incorporate the three techniques into Rushing Thunder Thirty-Six Forms and create a Body Refining Method with a more pronounced tempering effect.
He had already thought of a name for the Body Refining Method: the Primordial Thunder God 108 Forms Body Refining Method. After all, he had promised Ran Tianchi and the others that he would teach them this unique skill, so he naturally had to keep his word.
Although...
He had yet to create this unique skill.
"Hm?"
After practicing swordsmanship for a while, Baili Qingfeng discovered that five or six people had gathered at the entrance to the training room, quietly watching him practice.
Although they said nothing...
Baili Qingfeng was a young man, after all. He was never comfortable being watched by so many people while practicing martial arts...
Especially since several of the poses in Rushing Thunder Thirty-Six Forms were rather embarrassing.
He stopped at once and turned his gaze toward them.
Ran Tianchi hurried forward and introduced them to Baili Qingfeng: "Master Baili, let me introduce you. This is my father, Ran Tianying. This gentleman is Grandmaster Hong from Daluo Province."
"Master Baili?"
Grandmaster Hong smiled ambiguously. "You're a disciple of Jiang's Martial Hall in Sumen City?"
"Is something the matter?"
Baili Qingfeng did not answer.
"Jiang Clan disciple, you should kneel before me and beg for mercy now."
Grandmaster Hong sneered, his words ringing with certainty.
"Why?"
"Because..."
Grandmaster Hong stepped forward, his figure carrying a hint of pressure as he stared down Baili Qingfeng. "I am Hong Lie of Iron Sword Sect!"
