Transmigrated into a Grandpa, Embracing the Laid-Back Life

”The main structure of the formation, I completed long ago.” Luo Feng’s tone carried confidence, but also a hint of defeat. ”I used the ’Nine Revolutions Solar Yang Formation’ as the foundation, supplemented by the ’Seven Stars Stabilizing Element Chapter,’ which is sufficient to guide and refine over ninety percent of the violent fire spirit. In terms of the intricacy and power of the formation itself, I am confident it does not lose to any formation of the same tier.”

”The problem lies in... the carrier for the ’formation core.’” Luo Feng pointed to the node in the jade slip where the energy flow was most violent. ”The spiritual energy here is too explosive. I tried seven different third-tier spiritual materials, and even used a small piece of ’Millennium Fire Marrow Jade’ as the core. But they either shattered prematurely due to conflicting spiritual energy attributes, or because the natural spiritual patterns within them created imperceptibly minute ’spiritual pattern interference’ with my formation. Under sustained operation, this would form extremely subtle ’spiritual vibrations,’ causing the foundation of the formation to become unstable. At most, within half a month, cracks would inevitably appear in the formation core.”

Luo Feng looked at Su Ming, his expression complex. ”I consulted the ancient texts. The conclusion was, either find a fourth-tier or higher spiritual material with perfectly compatible attributes and absolutely uniform internal structure, but the cost is too high; or, I would need a grandmaster artifact forger who could completely disperse and reshape the internal spiritual patterns of the material, turning it into a pure ’blank carrier.’”

He paused, his tone carrying a tentative curiosity. ”I observed Junior Brother Su handling those low-tier formation plates, especially in material purification and basic rune inscription. You seem to have some... unconventional methods. I wonder, for this requirement of making a material ’absolutely obedient,’ or even ’absolutely blank,’ do you have any ideas?”

Su Ming instantly understood the crux of the problem.

”Spiritual pattern interference,” ”spiritual vibrations,” ”blank carrier”... These issues, which seemed mysterious and profound to traditional cultivators, were, from his and Lin Yu’s ”scientific perspective,” actually problems of uneven internal stress within the material, energy resonance, and microstructural defects.

”Senior Brother Luo’s problem, I might have some ideas about.” Su Ming didn’t speak in absolutes. ”I dare not claim to solve it, but I can try to make a ’carrier’ sample for Senior Brother to verify.”

”Oh?” A gleam flashed in Luo Feng’s eyes. ”What kind of spiritual material do you need? I’ll go prepare it immediately.”

”No need.” Su Ming shook his head and walked towards his workbench. ”Just use the most ordinary ’Mystic Iron Essence.’”

”Mystic Iron Essence?” Luo Feng was stunned. That was a basic material rarely used even for first-tier magical tools. ”Junior Brother Su, the spiritual energy impact at the core formation eye of the Earth Fire Cavern is comparable to a strike from a Golden Core cultivator. Mystic Iron Essence would probably vaporize instantly...””No harm in trying.” Su Ming smiled, offering no further explanation.

He took out a piece of Mystic Iron Essence. He didn’t use any fancy tools, just that same engraving knife marked with a standard ruler and his pure water spiritual energy.

Under Luo Feng’s skeptical and scrutinizing gaze, Su Ming began.

He didn’t inscribe any complex formations, nor did he channel much spiritual energy.

His water spiritual energy acted like the finest probe and scalpel, penetrating deep into the interior of the Mystic Iron Essence.

His goal wasn’t enchantment, nor inscription. It was—”combing” and ”reconstruction.”

Using water spiritual energy, gentle yet tenacious, he forcibly combed the chaotic, disordered microstructure within the Mystic Iron Essence into order. He washed away and squeezed out all the impurities, air bubbles, and internal stress nodes.

Simultaneously, utilizing the penetrating and accommodating properties of water spirit, he performed ”annealing” and ”quenching” at the molecular level, making its structure denser and more uniform.

This process resembled ”material refinement” and ”structural optimization” in modern industry more than traditional artifact forging.

One hour later, a piece of Mystic Iron, its surface smooth as a mirror, its color deep and dark, without a trace of impurity, lay on the workbench.

It still didn’t emit any spiritual light, but the material itself had become incredibly pure and uniform.

”Senior Brother Luo, you can try inscribing your formation core’s key runes onto this object.” Su Ming handed over this ”super Mystic Iron.”

Luo Feng took it with a mixture of doubt and belief. It felt slightly heavy and cool to the touch.

He took a deep breath, mobilized his divine sense and spiritual energy, and began carefully inscribing the complex and powerful core fire-control rune he had designed into the interior of this Mystic Iron.

The next moment, his eyes widened in shock!

Smooth!

Unbelievably smooth!

This seemingly ordinary Mystic Iron had an incredibly high degree of receptivity to his spiritual energy and divine sense! Its interior was like an absolutely calm, absolutely uniform ”sea of nothingness,” perfectly ”reflecting” and ”solidifying” every single stroke of the rune he outlined without the slightest distortion!

No spiritual pattern interference, no attribute conflict, because it was itself almost ”attribute-less”! It was merely a carrier, perfect to the extreme!

When the final rune was set, the entire piece of Mystic Iron glowed faintly before returning to its plain appearance. But

Luo Feng could clearly sense that a stable miniature spell formation had perfectly taken shape within it, merging with the Mystic Iron itself into a seamless whole!

”This... how is this possible?!” Luo Feng stared at the still unremarkable ”lump of iron” in his hand, feeling the powerful, stably operating formation within. The shock in his heart was beyond words.

Su Ming hadn’t defeated him in formation mastery. Instead, using a method he completely couldn’t comprehend, Su Ming had forged an unprecedented, long-dreamed-of perfect ”foundation” for his exquisite formation!

”Junior Brother Su... this isn’t the path of formations. This is practically... the creative work of ’turning stone into gold’!” Luo Feng looked at Su Ming, his gaze completely changed. It held respect for an unknown field and intense curiosity.

He had originally come just to try his luck, never expecting the other party to give him an answer that overturned his understanding.

”Senior Brother praises me too highly. It’s just some clever material processing tricks, hardly worthy of the elegant hall.” Su Ming smiled modestly.

Luo Feng took a deep breath, solemnly stored away this ”formation core,” and cupped his hands respectfully. ”Junior Brother Su, great kindness needs no verbal thanks. After I report the completion of the task, I will surely repay you generously! This... ’material processing’ knowledge of yours, I am very interested. I will definitely come again in the future to seek your guidance!”

Watching Luo Feng’s hurriedly departing back, filled with a desire for exploration, Su Ming knew he had planted a seed named ”science” in the heart of this formation genius.

”Master, it seems our ’basic science’ is still somewhat useful.”

”Nonsense!” Lin Yu said smugly inside the ring. ”He’s responsible for designing the CPU, we’re responsible for making the motherboard and heat sink! Clear division of labor, a powerful alliance! Now, let’s see who dares to call us amateurs!”

After seeing Luo Feng off, Su Ming stood in the courtyard, looking at the towering Cloud Concealment Main Peak in the distance.

”Master, it seems our ’Way of Survival’ business is about to expand into new territory.”

”Hehe, mechanisms?” Lin Yu laughed in the ring like an old fox. ”Disciple, think about it. If we carve formations onto a Gatling... oh no, a repeating crossbow... that image... tsk tsk tsk.”
