Life Spring, mutated into Life Goblin King

[Soon, following Tala, you entered elven territory, instantly captivated by its breathtaking beauty.]

[Ancient trees, some centuries or even millennia old, dominated the landscape. Elves inhabited natural hollows within these giants, while luminous fruits illuminated the forest canopy. At the center lay a pristine lake with crystal-clear waters. This dreamlike scenery left you spellbound.]

[Many elves regarded you nervously, though Tala's presence reassured them. Their curiosity stemmed not from unfamiliarity with monsters, but encountering an Emperor-class specimen like yourself. Rather than discomfort, you relished their attention, surrounded by the legendary beauty of elvenkind.]

[Tala explained: "Goburo, our customs require foreign monsters to meet with at least an elder for safety assessment."

"Understood."

"Please follow me."]

[Accompanied by Tala and the rescued elf girl Noran, you approached the elder's dwelling.]

[The elder, Misha, defied conventional imagery - a graceful, porcelain-skinned beauty whose appearance momentarily stunned even your resolute mind.]

["Aunt Misha, we've come to visit," Noran called softly.

Misha's gaze settled on you. Through your Oni King's Eye, you discerned her power - Peak Lord-class, nearing Emperor-class. Similar auras permeated the territory, alongside Sovereign-class presences you'd sensed previously, suggesting elven strength rivaled or surpassed the Oni.]

["Is this our guest?" Misha inquired.

"Yes, Aunt Misha. I ventured outside today and encountered danger. This kind sir saved me."

Misha's concern surfaced immediately: "Are you injured?"

"No, I'm fine."]

[After hearing the full account, Misha expressed profound gratitude: "Thank you, honored guest. Without your aid, we might have lost our precious Noran. Please allow us to host you at our Flower Grove Feast."]

[Unfamiliar with elven customs but accepting graciously, you anticipated a simple banquet. However, the evening revealed an extraordinary event - dancing elves, exotic fruits, and a bowl of pure, spirit-infused water you recognized as the legendary Life Spring.]

[Misha encouraged you to relax and enjoy. The Life Spring's essence permeated your being, purifying and amplifying your magic exponentially. Even the fruits carried extraordinary properties, each bite suffusing you with refreshing energy.]

[The feast lasted through the night, elevating your level remarkably. Following the celebration, the Elven Sovereign summoned you.]

[Her unparalleled beauty tested your composure as you struggled to maintain decorum.]

[Noticing your discomfort, the Sovereign adopted a playful tone: "So, our Emperor-class Goblin guest, what brings you to linger near our borders and rescue our precious Noran?"]

[You responded truthfully: "Your Majesty, I bear no ill will. While hunting, I chanced upon elves and became captivated by their beauty. Since then, I've frequented the area, occasionally interacting with your kind. Last night's events led to my invitation."]

[The Sovereign's emerald eyes studied you intently before she smiled: "Very well, I believe you. You may continue residing nearby, though not within our territory due to your miasma's potential contamination of the Life Spring. However, you're welcome to join our feasts occasionally."

"Understood. My gratitude."

"You're welcome."]

[Departing the Sovereign's abode, you settled in a nearby cave - no tree hollow could accommodate your stature.]

[When Oni envoys inquired about your return, you declined, determined to benefit from proximity to the Life Spring.]

[Year One Hundred Twenty: After decades near elven territory, with frequent visits from Hanamai and daily meetings with Kaina (now residing among elves as a half-elf), your regular consumption of Life Spring water had elevated you to level 77. Your astonishing advancement culminated in mutation into the Life Goblin King, with a level cap fourteen levels beyond standard Emperor-class.]
