A water-type trainer who specializes in dragon-type water.

The wait for the duckbill fire beast to cut the required steel was indeed long.

Mr. Mo seemed happy to communicate with this quick-thinking young man and did not hesitate to share what he knew.

"This is actually a well-known research finding in the UK, and it's an open secret within the field."

Old Mo sighed, "The problem is that, through energy resonance screening, we have found that there is more than one type of metallic element or natural alloy that can react significantly with aluminum steel dragon. Roughly speaking, there are at least six types."

"In Britain, they conducted individual induced evolution experiments on almost every metal that could react, investing a lot of resources, but unfortunately... none of them were successful. The Aluminum Steel Dragon did not show any signs of evolution."

Zhang Heng nodded thoughtfully. He had grasped the key information: multiple metals reacted, but none reacted individually.

This further confirms his conjecture—the tools needed for evolution are composite metals, and the key is the word "composite," not "single."

He tried to propose a hypothesis in a slightly leading tone: "So, Mr. Mo, is it possible that... the key to the evolution of the Aluminum Steel Dragon is not a single metal, but a completely new 'alloy' composed of multiple specific metals combined in a unique ratio and structure?"

Upon hearing this, Elder Mo was taken aback at first, then burst into laughter and patted Zhang Heng on the shoulder.

He said, "Haha, kid, you're quick-witted! Your idea certainly has great research potential. But..."

He changed the subject, his tone tinged with a hint of helplessness, and said, "The possibility of this kind of 'alloy' that you're imagining has already been systematically explored by the team in Britain several years ago."

"They tried almost every possible combination: melting all six metals into a single homogeneous alloy; pairing them in pairs; or grouping them in groups of three..."

"We tried countless combinations and crafted all sorts of alloy ingots, giving them to different aluminum steel dragons. And the result? They all disappeared without a trace, and not a single aluminum steel dragon reacted as a result."

Finally, Mr. Mo revealed the core reason why this ambitious plan was ultimately shelved.

He said, "Moreover, you should know that the smelting and alloying of high-purity special metals is extremely complex and costly. Every new alloy formula means a huge depletion of metal inventory and an astronomical amount of capital investment."

"After countless failures and seeing no clear direction, even the financially powerful British Alliance could not withstand this bottomless drain and officially suspended this large-scale screening experiment as early as last year."

After listening, Zhang Heng nodded calmly on the surface to show his understanding, but his heart was in turmoil.

It seems that researchers around the world have considered the path of "composite" technology, but they seem to have entered a labyrinth of thinking, believing that composite is merely a physical fusion.

They lacked a crucial "key," a catalyst that could truly "activate" this composite, causing a qualitative change that aligns with the evolutionary essence of aluminum-steel dragons.

He pondered for a moment, then turned his gaze back to the ancient beast's remains in the center of the arena, radiating an aura of antiquity. As if casually, he spoke softly, in a tone tinged with hypothesis and inquiry:

"Elder Mo... I was thinking, since simple compounding of multiple metals is ineffective, is it because those alloys... lack a catalyst that can truly 'integrate' them and cause a fundamental transformation of the metals?"

He paused, his gaze fixed on Regischiru, as if he could see through the indestructible shell to the essence within, an essence beyond ordinary metal.

"A special metal... that may possess extremely strong inclusiveness, assimilative properties, or even some kind of 'life' or 'rule' characteristics?"

Mo Tieshan didn't pay attention at first, but when his gaze followed Zhang Heng's and finally landed on the body of Registeel that was emitting a faint divine power fluctuation, the casual look on his face instantly disappeared.

His pupils contracted slightly, his gaze suddenly sharpened, and a glint of light flashed behind his glasses!

He was frozen in place as if struck by lightning.

"Medicinal catalyst...integration...encompassion...divine metal..."

He unconsciously repeated these keywords, his withered fingers trembling slightly with excitement.

Zhang Heng's words were like a key, suddenly breaking through a layer of paper that he had been thinking about for a long time but had never been able to break through!

At this moment, all the clues seemed to point to a crazy yet perfectly reasonable possibility that he had never dared to imagine before!

In that silent moment when sparks of thought collided intensely—

“Bang!!!”

A deafening roar, far louder than the previous cutting noise, suddenly came from the direction of the research platform!

The two of them turned their heads sharply at the same time.

On Regischiru's massive metal body, a relatively slender but thicker than an adult's thigh had broken off at the root and crashed heavily onto the specially made alloy platform with a heart-stopping roar!

It turned out that the two experienced molluscs did not choose to attack Registeel's thickest limbs.

Instead, they precisely located and concentrated on cutting the relatively weak and stress-complex joints in the limb connection structure.

It was this strategy, coupled with their persistent high-temperature melting, that allowed them to successfully remove the arm containing the pure steel-type divine beast's primordial energy in a relatively "short" time!

At the fractured section, a strange, dark silver luster, resembling the core of a star, emanated from which wisps of indescribable energy fluctuations.

Mo Tieshan stared intently at the severed divine beast arm, then suddenly turned to look at Zhang Heng, his breathing becoming somewhat rapid.

His eyes were filled with unprecedented fervor and inquiry, as if he were looking at a huge treasure waiting to be opened, or as if he were looking at a genius, or rather, a “revelation”, who had put forward a groundbreaking hypothesis.

Zhang Heng's suggestion, along with the "materials" they had just acquired from the very origin of a Steel-type Divine Beast, seemed to be pointing towards a new research direction.

The air inside the research institute seemed to become heavy and full of infinite possibilities once again because of the severed arm and Old Mo's burning gaze.
