Just as the wired telegraph experiment succeeded, by the central lake of the academy.
The golden sunlight illuminated the lake surface, making it sparkle. The figures of two youths were reflected in the water.
"Seriously, Little Xiao, can you stop looking at it?"
By the lake, Wang Lin looked helplessly at Xiao Hongchen, who was walking slowly, completely absorbed in the thesis about the wireless telegraph in his hand.
Wang Lin regretted taking out this thesis. Xiao Hongchen was supposed to lead him here to the central lake to find Ji Juechen, but the moment Xiao Hongchen saw the thesis, he became utterly engrossed.
"Don't bother me. The Sword Lunatic isn't going to run away."
Xiao Hongchen waved his hand, concentrating entirely on the thesis. Actually, it was no wonder Xiao Hongchen was so captivated.
Compared to the wired telegraph, the wireless telegraph was truly a cross-era product. The principles of electromagnetic signal conversion within it led directly to the supreme path of communication, guiding the development of an entire era.
In Wang Lin's past life, the world could not function without electromagnetic wave communication technology. Whether it was long and medium waves used for communication over sea and underground.
Or short waves used for long-distance communication, they were all indispensable human technologies.
Not to mention, as short waves developed to the millimeter wave level, they could be used in high-precision measurement and positioning, such as radar and GPS positioning systems.
Without mentioning anything else, in terms of strategic significance, a GPS positioning system could allow the Sun Moon Empire's Rank 9 fixed Soul Missiles to accurately lock onto Shrek Academy from Mingdu.
This was equivalent to giving the Soul Tool a seeing eye that saw the world. So, Wang Lin only urged him and didn't snatch the thesis back.
If Xiao Hongchen somehow understood it and later became an expert in this field, the time wasted would be well worth it.
However, to Wang Lin's relief, not much time was wasted. In the distance, he saw an handsome man in white standing on the opposite bank of the lake.
The man had long black hair tied up with a thin cord and draped behind him. His face was pale and stern, looking somewhat thin, in his early twenties. He was clutching a long black sword that resembled a fire poker.
"Little Xiao, quick look, is that Ji Juechen?"
Wang Lin reached out and patted Xiao Hongchen, who was looking down at the thesis. Xiao Hongchen looked up, clearly saw the man's appearance, and nodded.
"Yes, we found the person. You go over yourself, don't disturb me."
Wang Lin looked at Xiao Hongchen helplessly, punched him on the shoulder, and turned to walk towards Ji Juechen.
As he got closer, Wang Lin realized that Ji Juechen was looking down at the lake, seemingly lost in thought, as if gaining some insight.
However, just as he was about thirty meters away from Ji Juechen, a woman with an ordinary appearance suddenly emerged from the shadows.
The woman was tall, and at first glance, she looked almost thirty years old. She blocked Wang Lin's path, looking at him with extreme vigilance.
"What do you want to do?"
"Uh, and you are?"
Wang Lin noticed the Rank 6 Soul Engineer badge on the woman's chest, realizing she was a Rank 6 Soul Engineer from the Mingde Hall.
"Jing Ziyan. I should be your Senior Sister, young one. This is not a place you should be. Hurry and leave."
Jing Ziyan's vigilance lessened considerably, seemingly noticing Wang Lin's young age.
Wang Lin's mouth twitched at the words "young one." He darkened his face, ignoring Jing Ziyan, and instead shouted to Ji Juechen, who was standing by the lake.
"The sword is the extension of the body. Train the mind, then the heart, then the body in swordsmanship!"
Upon hearing these simple words, Ji Juechen, standing by the lake, suddenly shook, his entire body's sword momentum condensing. He turned abruptly, his eyes bursting with sharp sword intent, instantly spotting Wang Lin, who had just spoken.
His figure flashed quickly, his white clothes fluttering.
Buzz!
The sound of a sword humming rang out. In a brief moment, Ji Juechen arrived directly in front of Wang Lin, the sword intent in his black eyes pressuring.
Wang Lin, however, seemed to see nothing, his gray eyes meeting Ji Juechen's gaze directly, completely unaffected by the sword intent in Ji Juechen's eyes.
This peculiar scene stunned Jing Ziyan. In her impression, few people could meet the gaze of a solidified sword intent from Ji Juechen and not fall into a disadvantaged position.
"What did you just say?"
Wang Lin could see the excitement and desire in Ji Juechen's eyes. He immediately repeated earnestly: "The sword is the extension of the body. Train the mind, then the heart, then the body in swordsmanship!"
As these words left his mouth again, Ji Juechen instantly froze in place, and the sword intent permeating his body vanished at that moment.
Wang Lin, who was standing face-to-face with Ji Juechen, suddenly noticed that all the extraordinary aura on Ji Juechen's body completely disappeared.
At this moment, Ji Juechen seemed like an ordinary person holding a black fire poker.
"Hmm!?"
Jing Ziyan suddenly tensed up, grabbing Wang Lin and pulling him to the side.
"Hurry up! Juechen is having a moment of enlightenment about the sword!"
As she spoke, Wang Lin was pulled to the side by Jing Ziyan. It was at this moment that a concentrated sword intent suddenly erupted from Ji Juechen's body.
His aura instantly solidified. The long sword in his arms, which looked like a fire poker, entered his hand. Ji Juechen gripped the long sword, turned, and simply swung it forcefully at the lake surface.
Buzz!
The long sword hummed. A soaring sword energy struck the sparkling lake surface, instantly creating a huge splash over five meters high.
Bang!
After doing all this, Ji Juechen sheathed his sword, turned to look at Wang Lin in one fluid motion. Holding his long sword again, he bowed to Wang Lin, who had retreated ten meters away.
"Please, teach me swordsmanship!"
"Uh, you broke through!?"
Wang Lin felt the change in Ji Juechen's aura, and his heart was astonished. He had only spoken a line he had read in a novel in his past life.
This Ji Juechen actually gained an insight and broke through. Wang Lin could only say that he truly lived up to the name of a natural born Sword Dao Saint Body.
Thinking this, Wang Lin still decided not to lie. He didn't understand the sword. If he were to teach a natural Sword Dao Saint Body swordsmanship, he would be exposed sooner or later. It was better to tell the truth.
"I don't know swordsmanship. That sentence just now was something I read from an ancient book. By the way, my name is Wang Lin."
"Ji Juechen." Ji Juechen stood up straight, his eyes filled with desire. "Can you tell me which ancient book it was?"
"The ancient book is lost," Wang Lin casually made up. He didn't have any ancient book. "However, there is a set of basic sword techniques in the ancient book. I don't know if it's real, but if you want to learn, I can teach you."
The basic sword technique Wang Lin referred to was what an old Master taught him during a trip to Wudang Mountain in his past life. If it weren't for his Martial Soul being the Brain, he might not even remember it.
However, this basic sword technique was truly a basic sword technique. Even in Douluo, it had no extraordinary effects, unlike the Eight Sections of Diamond Power.
"Sword technique?" Ji Juechen immediately became animated when he heard this. "Please teach me, Wang Lin!"
"Uh." Wang Lin paused, suddenly realizing he didn't have a sword on him. Fortunately, Jing Ziyan extended a helping hand at this moment. She took out a female-style long sword and handed it to Wang Lin.
"This is what I occasionally use when practicing swordsmanship with Juechen. You teach him, and I can help you with making Soul Tools," Jing Ziyan said earnestly.
