Upon seeing Lynn's peculiar actions, Elok took a step back, startled. However, he quickly realized that no flames or frost had emerged, and he hadn't been attacked.
"What is the professor doing?" Pierce, too, was puzzled. It couldn't be an attempt to scare them, could it?
"This must be some new kind of magic." Jenny guessed, then looked at both of them and said rapidly, "Our only chance is to go on the offensive. I'll take the lead this time, and you two assist."
With no other ideas in mind, the two nodded, and just as they were about to cast their spells again, their bodies suddenly froze. Elok's face twisted in agony, and he collapsed to the ground without warning.
Pierce's reaction mirrored Elok's; he clutched his chest tightly, veins pulsing on his forehead, as if enduring immense pain.
Jenny managed to maintain her composure a bit better, struggling to stay on his feet. However, his heart felt like it was being squeezed, matching the erratic rhythm of Lynn's trembling finger. It pulsed like thunder one moment and slowed like a sluggish river the next, an uncomfortable and bizarre sensation that left Jenny powerless to resist.
Their brains, too, suffered from the disrupted blood supply, and after a couple of seconds, the feeling gradually subsided. But in the next moment, their lungs and livers suffered a similar assault.
"I surrender. I give up." Elok, writhing on the ground, called out loudly, his face a mixture of fear and confusion.
Seeing that the three of them had reached their limits, Lynn stopped casting the new magic to prevent any side effects.
Jenny, Elok, and Pierce took several minutes to recover from the ordeal. They looked at Lynn with a mixture of fear and relief. Just moments ago, they had feared their hearts might explode, but they couldn't figure out where the attack had come from.
"Professor, what kind of magic was that you just used? Some kind of curse?" Elok asked, his voice still trembling. This eerie magic even reminded him of the cursed sorcery that was infamous in the Wizard Land.
"Of course not." Lynn chuckled and shook his head, intentionally keeping the explanation vague.
In reality, this magic was based on the phenomenon of resonance. In scientific terms, it involves a physical system absorbing more energy from its surroundings when vibrating at its natural frequency.
In the conventional terminology of wizards, everything in the world was made up of elements, each with its own inherent frequency. When two objects' frequencies converged, they could influence each other.
For example, the average human body resonated at 7.5 Hertz, with different parts having their own resonant frequencies. Internal organs resonated at 4-6 Hertz, while the head's resonant frequency was 8-12 Hertz.
Lynn's method involved creating a tiny magic wave that made vibrations as close as possible to the heart's frequency, inducing resonance and causing rapid disruptions to the heart's oscillations, ultimately leading to internal damage.
This magic was not only hard to detect, but it attacked at the molecular and atomic levels. Unless one was prepared, it was challenging to defend against.
However, during the experiment, Lynn realized that formal wizards like Jenny were more resilient to resonance magic than apprentices like Elok and Pierce.
Although he intentionally reduced the magic's power to avoid causing harm, he also understood that using resonance principles to directly kill powerful wizards wasn't easy. At best, it could have a slight impact on critical moments.
It was a clever magic but one Lynn chose to keep its principles secret to prevent the development of countermeasures.
Jenny and the others were intensely curious about this strange and curse-like magic, but seeing that the professor had no intention of explaining, they suppressed their growing curiosity and asked, "What about the magic that deflected the flames and frost?"
"That's called a Deflection Force Field." Lynn replied, this time not concealing anything.
"Deflection Force Field? Isn't that a fourth-tier magic? Professor Lynn, have you reached the Grand Wizard level?" Phillip, who had been watching from the sidelines, exclaimed in astonishment and excitement. Being able to use force field magic effortlessly was a hallmark of a Grand Wizard.
Jenny, Elok, and Pierce also looked at Lynn with amazement. The reason for the immense power of the explosion earlier was the Deflection Force Field, akin to a turtle shell that seemed impenetrable.
"No, I haven't," Lynn shook his head, denying Phillip's and the others' assumptions. He then smiled and explained, "I merely took a shortcut. I named it 'Secondary Deflection Force Field.' It should belong to the upper-tier third-tier magic category."
After calculating the gravitational constant, Lynn could effectively reduce the difficulty of casting force field magic. However, the Deflection Force Field was originally a magic only Grand Wizards could use. Due to differences in magical power and computational abilities, the protective effect was naturally not as robust as the original version, hence the "Secondary" designation.
Moreover, force field magic wasn't invincible. Matter and energy themselves could affect spacetime, making it possible for powerful spells to penetrate the barrier.
The other issue was magic consumption. Even with reduced requirements, the magic consumed a terrifying amount of energy. Under the most abundant magical conditions, it could only be maintained for a short fifteen seconds.
The peculiar resonance magic that Lynn had just released was a byproduct of his research into force field magic.
Back when he was fighting Helram in the Screaming Tower, Helram had cast a wide-ranging ripple of magic. Lynn had to dodge this spell to avoid being pierced by the iron thorns that came flying towards him.
This incident had left a deep impression on him, and he had spent these days contemplating how to combine this ripple magic with force field magic.
Through a strong magic wave, he could induce changes in space curvature, causing spacetime to oscillate like water ripples, bypassing the enemy's defenses from a spatial perspective and killing them. Lynn had named this envisioned magic [Spatial Wave]
But judging from the magic's principles, it was at least a fourth-tier or even fifth-tier magic. Lynn's several attempts had ended in failure, and with his current computational power and magical reserves, he wouldn't be able to meet the minimum standards to cast this magic.
Unless he could temporarily surpass his limits as he did in the past, borrowing others' computational power to reach the minimum threshold for casting this magic.
