Transmigrated into a Grandpa, Embracing the Laid-Back Life-Chapter 215: Soul Power Refueling Station

"Source Substance..." Su Ming chewed on the word, his gaze burning as he stared at the formation plate that was still swallowing and spewing gray mist.

What kind of useless formation was this?

This was clearly a "self-service cafeteria" exclusively for his master!

"Continue! Disciple, don't stop! This master feels he can still eat two more bowls!" Lin Yu urged.

"Aye aye!"

Su Ming immediately perked up, no longer stingy with his spiritual energy, and maintained the formation's operation at full power.

That night, the temperature inside the meditation room was frighteningly low, but the hearts of the master and disciple were burning with passion.

Su Ming was like a diligent boiler worker, constantly adjusting his spiritual energy output to maintain the formation's stability; while Lin Yu was like a picky gourmet, manipulating the Xuantian ring to precisely pick out those precious, thread-thin strands of "grayish-brown source substance" from the large masses of gray "waste material."

It wasn't until the first light of dawn appeared at the horizon and the Void Stone Powder was completely exhausted that the formation plate reluctantly ceased operation.

Su Ming collapsed on the floor, exhausted, his fingers frozen stiff.

But in his mind, Lin Yu's condition was unprecedentedly good.

"Disciple, look."

In the Consciousness Sea, Lin Yu extended his hand.

His originally semi-transparent, even somewhat blurry palm, though still illusory, now had sharp, clear edges and lines, and even the patterns of his fingerprints could be seen clearly.

"Though the total amount gained this night is meager, its quality is extremely high. The nourishment to the soul's origin far surpasses ordinary nurturing! If we can obtain it long-term, not only is there hope for repairing soul injuries, perhaps... even reforming a more stable soul body foundation is not an extravagant hope!" Lin Yu exclaimed with emotion, his tone filled with hope.

Su Ming rubbed his numb, frozen hands, grinning as he said, "Since we know this formation is of great use to Master, even if it costs more, it's worth it. It's a pity the 'Source Substance' output seems extremely unstable, and the Void Stone Powder consumption is huge..."

"No matter! Since we've already found the path, what remains is to explore the patterns and accumulate resources." Lin Yu's heroic spirit surged forth, "This formation will be our top priority from now on! Once this master's soul body stabilizes a bit more, perhaps I can uncover more wondrous uses of the Xuantian ring. By then, the foundation for us, master and disciple, will be even stronger!"

......

Although they had discovered the treasure of "grayish-brown source substance," in the following days, the master and disciple duo fell into a new frustration.

The yield was too low.

Adhering to his usual meticulousness, Su Ming took out a blank jade slip and, using his divine sense as a brush, meticulously recorded the various data of each formation deployment.

"Day Wuchen, third quarter of the Zi hour, deployed formation in the meditation room, consumed half a *qian* of Void Stone Powder, lasted half a shichen, obtained three strands of 'grayish-brown source substance,' as fine as floating silk, almost imperceptible."

"Day Wuchen, beginning of the Chou hour, tried again, lasted one shichen, consumed one *qian* of powder, obtained five strands of source substance, slightly thicker than before, yet extraction was difficult, with eight or nine out of ten dispersing into the ambient spiritual energy of the void."

"Day Jisi, exact Wu hour, tried in the courtyard under sunlight, formation operation was sluggish, almost no source substance precipitated, instead it slightly disturbed the surrounding spiritual energy, fearing it might attract attention, quickly dismantled."

Su Ming looked at the record book in his hand, his brow tightly furrowed, "Master, this efficiency is no good!"

"And this Void Stone Powder is almost gone too." Lin Yu also wore a worried expression.

"There must be some pattern we haven't discovered."

"Pattern..." Su Ming lightly tapped the table with his knuckles, his gaze shifting to the gradually darkening sky outside the window, "Master, you once said that a formation's 'spirit attraction' emphasizes the right time, the right place, and the harmony of the formation. For the right time, we've tried different hours; the transition between Zi and Chou seems to have some benefit. For the harmony of the formation, it relies on the gentle guidance of the Like Water Art and the Xuantian ring's special absorption. Only this 'right place'..."

He paused, then continued, "When this disciple usually practices the Like Water Art by the ancient well in the courtyard, I feel the water spiritual energy is particularly active and abundant. That ancient well is very old; perhaps there is a subtle water vein beneath it. Could that be considered a special kind of 'earth energy node'? The void is ethereal; does it attract its power?"

"Not only that," Lin Yu said, "I've observed recently that the location of that ancient well seems to be exactly on a tiny node of the Cloud Hidden Sect's earth veins. Although it's not some major spiritual vein, it excels in being unobstructed. Since this formation is called 'Spirit Attraction,' why don't we try changing locations?"

"Tonight happens to be the full moon night." Su Ming looked up out the window, "The moonlight is at its strongest, the tidal gravitational pull is greatest; perhaps we can lure the 'big fish' out of the void."

They decided to act immediately.

Deep into the night, the moon was high in the sky.

Courtyard D-7 was deathly silent, with only the occasional chirping of insects.

Su Ming quietly approached the ancient well and placed the dark gold formation plate on the well's edge.

The cold, clear moonlight spilled onto the well's water surface, sparkling and shimmering, the reflected light perfectly illuminating the bottom of the formation plate.

"The last bit of Void Stone Powder, all in."

Without hesitation, Su Ming poured the last bit of powder from the bottle's bottom into the formation.

*Hummm—*

This time, the formation plate's reaction was completely different from before.

It didn't emit that low, dull hum, but produced a strange resonance.

The calm water surface in the well rippled without any wind, spreading out circles of fine, uniform ripples. The moonlight shattered within them, dancing and shimmering.

As Su Ming infused his spiritual energy, the ancient dark red patterns on the formation plate now faintly took on a layer of silvery radiance, reflecting with the moon in the sky and the moon's reflection in the well, creating a mysterious and wonderful scene.

Su Ming felt that the water spiritual energy he was outputting circulated more smoothly than in any previous attempt, as if the formation had achieved some kind of harmonious resonance with the surrounding environment and the moon in the sky.

"Now! Maintain it!" Lin Yu commanded in a low voice, his tone filled with anticipation.

In the center of the formation plate, the void node appeared once more.

"Here it comes!" Lin Yu exclaimed softly.

This time, there were no large masses of gray exhaust.

From the void node at the center of the formation plate, a familiar gray thread first seeped out.

Immediately following, was a thread... of silver!

That silver thread was extremely fine, yet dazzlingly bright, writhing like a living creature under the moonlight.

"Silver?!" Su Ming was startled.

"Don't mind the color! Get closer quickly! This thing is potent! The quality of this substance far surpasses the grayish-brown!" Lin Yu's voice even changed pitch.

The Xuantian ring shone with intense light, its suction force more violent than any previous time.

*Ssss...*

The silver thread vanished into the ring.

In that instant, Su Ming felt a refreshing, tingling numbness spread from where the Xuantian ring was worn on his left hand, quickly spreading through half his body. Not only was there no discomfort, it instead cleared his mind, and his divine sense seemed to become a bit sharper.

Inside the ring, the illusory form of Lin Yu's soul body shone with silver light, its degree of solidity visibly increased by a notch, and his facial features became even clearer.

"Good! This substance is highly nourishing!" Lin Yu was both shocked and overjoyed.

But this wasn't the end.

Just after the silver thread was absorbed, it was as if the void node's meridians had been unblocked.

*Gurgle.*

A soft sound, as if something had bubbled up from deep water.

A substance, only the size of a grain of rice yet emitting a faint golden halo, slowly drifted out.

The moment this thing appeared, the surrounding air was no longer just cold, but became exceptionally viscous, as if time itself had slowed down in that moment.
