"Oh, splendid!" Qian Jin nodded happily. Ever since following Teacher Adams, every time he saw his teacher preparing an experiment, he always wanted to step forward and help, but was always stopped.

"Do you want to help, or do you want to cause trouble? Stay on the side and watch."

Qian Jin had heard Teacher Adams say the exact same sentence countless times. To be actively asked to assist today meant he had made considerable progress in potions.

One experiment later, Qian Jin was so busy he wished he had two extra hands, narrowly avoiding several mishaps that would have ruined Adams’s experiment.

"Passable," Adams nodded in satisfaction, looking at the sweat-drenched Qian Jin. "You can finally assist me with the preliminary experiments. Keep working hard! In the future, you might even be able to assist with intermediate experiments..."

Qian Jin nodded listlessly. After all that exhausting labor, which felt harder than a life-and-death battle, he only qualified to assist with preliminary experiments. The road to becoming a Master Craftsman was still incredibly long!

"Kid, come here for a moment." Oulala shook a canned potion in his hand. Qian Jin knew he was next up to be the test subject for a mysterious potion.

The Hundredfold Volcano Potion! Qian Jin endured for an hour, then worked busily for another two hours before finally leaving the mysterious potion room.

"Kid, come here for a moment."

Qian Jin looked at Akenash, unsure whether to laugh or cry. This Rune Master, who looked like a petite loli, was also calling him "kid." Alas! It was all because his rune skills were lackluster.

"Today, I'll teach you a new system," Akenash said with a troubled look, a hint of complaint in his voice. "Stand in that disc in the backyard."

Qian Jin passed through the front desk into the backyard. He saw a large, five-meter-diameter metal disc placed in the yard. It was forged primarily from Iron Essence, integrated with a dozen different rare metallic materials into a specialized object. Intricate and dizzying rune magic arrays were carved upon it, making it impossible for him to understand what it was immediately.

"I’ve reviewed that thing you told me about," Akenash said, placing several different colored magic crystals around the magic array. "The idea is good," but there are other hidden dangers. That device is supposed to activate some kind of power, right?"

Qian Jin nodded, knowing Akenash was referring to the data he had previously handed over concerning the second altar of the Nine-Headed Serpent bloodline.

"Although the data you provided was incomplete, the design of that thing indeed has inherent flaws. The concept is sound, and many aspects were initially approached correctly, such as the idea of forceful transplantation. It should work, but the method used—suppression—is wrong. Suppressing what you forcefully transplanted usually doesn't show problems during normal times, but when engaged in a top-tier fierce battle, the suppressed elements might erupt, causing ability chaos..."

Qian Jin’s eyes suddenly lit up. The strong members of the Qian family had extensive records regarding the Nine-Headed Serpent bloodline. There was indeed a case where the Qian Family Patriarch, during a critical moment in a fierce battle on the Human-Demon Battlefield, suddenly suffered ability chaos and was killed.

"The more powerful one becomes, the more severe this issue gets," Akenash stated seriously. "When the power is activated to its peak state, ability chaos will frequently occur in daily life, and sometimes even periodic, inexplicable pain will strike the body."

Qian Jin stared blankly at Akenash. It was absolutely correct! This was too accurate! The records of the Qian family ancestors mentioned more than once that even the Heavenly Apex Awakened Warriors of the Nine-Headed Serpent bloodline experienced this exact situation in their lives! Could it be that the Head of the Nine-Headed Serpent Bloodline Warriors, Serpent Emperor Lord Pan Hongji, also suffered from this? He remembered once, while eating, the chopsticks had slipped from his hands.

How could the Serpent Emperor, with his immense power, drop his chopsticks? Qian Jin furrowed his brow tightly. That’s right! He hadn't noticed that detail before, but looking back now, the Serpent Emperor's expression had briefly soured at that moment.

"Though it's a flawed product, the concept is still commendable."

Akenash muttered to himself as he placed the final magic crystal. Qian Jin stood in the middle of the disc and noticed that the dim magic runes of the array began to light up... in just one second...

"Holy hell!"

Qian Jin couldn't help but blurt out a curse. His entire body suddenly compressed downward before slowly pushing his spine back up.

Twentyfold! In an instant, a gravity of twenty times his normal weight slammed down! If he hadn't been careful and noticed, he really would have been crushed by the sudden surge of gravity.

Qian Jin looked down at the disc beneath his feet and finally began to understand what this thing was—it was a magical gravity device! Somewhat similar to the Qian Family's Kun Combat Skill.

"Hmm? Not bad."

Akenash crouched in front of the disc and gently tapped it a few times with his slender fingers. The magic runes, which had dimmed momentarily, began to light up sequentially.

Gravity twenty-five times, thirty times... thirty-five times...

Qian Jin’s entire skeletal structure was making crackling sounds. The First Dou Heart within his body had already begun to spin: ten thousand rotations, twenty thousand rotations, thirty thousand rotations, forty thousand rotations... forty-three thousand, forty-five thousand, forty-seven thousand—the limit!

He who could once easily surpass a center rotation speed of one hundred thousand turns was now reaching his limit at forty-seven thousand rotations even while exerting his absolute maximum. He couldn't increase the speed any further.

What was this? Qian Jin’s hair instantly stood on end. This was... the genuine Qian Family Kun Combat Skill! That’s right! The characteristics of the Qian Family's Kun Combat Skill, which he had mentioned to Teacher Akenash, were being perfectly simulated by this Rune Master using the power of runes and magic arrays with one hundred percent accuracy.

The true Kun Combat Skill didn't just alter the gravitational field around an opponent; it could even alter the gravitational field inside the opponent’s body. For example, the rotation speed of Dou Qi would be severely squeezed by intense gravity, heavily affecting its spin rate and completely preventing true explosive power from being unleashed.

Unbelievable! Absolutely unbelievable! Qian Jin stared in disbelief at the frequently flashing magic runes around him. Thirty-seven times gravity made movement genuinely difficult. The rotation speed of his Dou Qi felt as if it were trapped by spider silk, turning with agonizing stiffness.

"Time was short, and materials were lacking," Akenash commented, crouching before the specialized magic device and staring at the shining runes without looking up. "It's a bit small, and its functions are incomplete. A flawed product."

Flawed product? Qian Jin stood in the device, struggling to wave his arm. Such an excellent thing was still considered flawed? If he could practice here, he would gain some immunity against the dreaded Kun Combat Skill used by the Qian Family when he encountered them in the future.

"You're moving quite fast," Akenash noted, continuing to tap on the magic device with his fingers. "Increasing the gravity further is meaningless. Let me add some of the ideas you mentioned earlier."

Rumble!

The gravity field instantly became intensely cold, as if a person had been stripped naked and thrown into an ice cavern filled with ice shards.

Cold! Freezing! Qian Jin instinctively shivered. The Dou Qi rotation speed, which had just been at forty-seven thousand RPM, instantly began to drop: forty-five thousand... forty-three thousand, forty thousand... thirty-seven thousand... thirty thousand... twenty-six thousand...

In just two seconds, the Dou Heart rotation speed, which once reached one hundred thousand RPM per minute, had plummeted to a pathetic twenty-three thousand RPM. His Dou Meridians and Dou Apertures felt completely frozen solid!

This wasn't mere common cold; it was like the Kun Combat Skill, driving the cold deep inside his body for rapid freezing. The rotation speed of twenty-three thousand RPM was still slowly decreasing.

Unbearable! The Third Dou Heart! Qian Jin’s eyes snapped open, shaking the frost from his eyebrows. The third Dou Heart on his forehead began to spin wildly at that moment, recovering to twenty-four thousand RPM, twenty-six thousand, thirty thousand...

The speed began to recover rapidly. Qian Jin felt warmth slowly returning to his body.

"Interesting," Akenash raised an eyebrow, his finger lighting up another rune. The dozen magic crystals emitted a harsh grinding sound as massive amounts of magical power were fed into the magic device. A colder current of frigid air swept in!

Instantly, the recovered rotation speed began to be suppressed again: twenty-seven thousand, twenty-three thousand... twenty thousand... nineteen thousand!

Thirty-five times gravity, combined with the freezing power, managed to push Qian Jin’s Dou Qi rotation speed below twenty thousand for the very first time.

Heart of Earth Fire! Qian Jin clenched his fists. The almost frozen Dou Qi instantly seemed to transform into melting ice, and a sliver of rotation speed began to recover again.

Akenash rested his chin on his hand, smiling faintly as he watched Qian Jin inside the magic device.

In mere seconds, the first burst from the Heart of Earth Fire ended. The slightly recovered speed was instantly frozen over again.

Helplessly, Qian Jin could only unleash the Heart of Earth Fire’s rotation for a second time, a third time, and a fourth time.

In less than a minute, the Heart of Earth Fire had been exploded six times, completely exhausting its reserves. When he tried to summon it again, he found that this Heart of Earth Fire felt like a dormant volcano—possessing surging power, yet completely unresponsive.

The slightly recovered Dou Qi rotation speed began to be sealed by ice once more.

"Don't leave the range of this magic device," Akenash said with a smile, raising his index finger and slowly pressing towards the edge of the device.

For the first time, Qian Jin felt that Akenash’s slender finger held a power far exceeding the fists, feet, or weapons of many strong individuals. A sense of uncertainty washed over his entire body.

Ding! Another rune lit up.

Brilliance! Rows of bizarre magic runes began to appear before Qian Jin’s eyes, including projections of Akenash carving runes.

"This... this is..."

Qian Jin stared blankly at the brilliance and began to understand. This Rune Master intended for him to continue learning rune knowledge within this environment, while simultaneously training his combat strength.

"Take this," Akenash tossed several materials and tools into the device. "Practice inside."

An Inscriber is a profession where one must carve slowly, ensuring absolutely no mistakes can occur.

But Akenash demanded speed—to carve as quickly as possible, not slowly.
