The Fire God scrutinized Lu Ren's physique, and suddenly the flickering flames surged, an intense heat that could easily incinerate mountains and boil seas rushed forward, a suffocating heat that almost made Lu Ren feel like his body was being ignited.

His eyes flickered, raising his arm to examine it, noticing that his skin seemed to have dried slightly under this heat; such heat, if placed in the real world, could turn a planet into dust.

This heat came quickly and receded equally swiftly, lasting only two or three seconds before it abruptly contracted and returned to the stone furnace.

The Fire God looked at Lu Ren with surprise, exclaiming with some astonishment: "Kid's physique is indeed tough, to remain unmoved under the Primordial Fire, not even the body showed any change."

Lu Ren admired, "The Fire God's heat is formidable, I thought my physique was strong enough, but didn't expect that just two or three seconds of exposure to the heat caused the skin to begin to rapidly dry and crack; if exposed to such a condition for a long time, the moisture in the body would likely be burned dry."

"Eh, getting old, not as useful as before, even allowing the heat to spread for too long would be impossible, but I wouldn't burn you into a mummified corpse."

Beside them, Huang Yaying saw the exchange of compliments between man and flame, and couldn't help but step forward: "If you keep flattering each other like this, time will run out."

Only then did the Fire God cease, and Lu Ren quietly sighed, realizing that while exchanging compliments can be pleasant for both parties, it can become a bit too false if overdone.

Then Huang Yaying cast several True Techniques, activating the engraved markings above the stone furnace, causing the engraved Array Marks above to begin glowing faintly, as vast amounts of Primordial Qi converged from all directions.

Under the nourishment of the Primordial Qi, the flames of the Fire God which were originally a pale gold began to transform into a pure golden hue, resembling flowing mercury within the stone furnace.

"Get over and work the bellows!"

Huang Yaying stared at the gradually heating flames within the stone furnace, giving orders without turning her head.

Lu Ren didn't hesitate, moving to the other side of the stone furnace where he saw a hand-operated bellows device, and immediately reached out and grabbed it, while Huang Yaying pointed her finger in a rubbing motion, a Spiritual Light shooting to his side.

"This is the Fire Control Spell; if you show exceptional talent, I'll truly take you on as an apprentice and teach you to Cast Soldier, giving you at least a stable livelihood in this Border City without the need to join the military and take unnecessary risks."

Grasping the Spiritual Light floating before him, Lu Ren then felt paragraphs of tens of thousands of words of the Artifact Refining True Skill turning into a flowing stream and entering his mind once he confirmed it was safe, letting it rush into his brain.

It took only a few breaths for Lu Ren to finish reading the tens of thousands of words of the Low-Tier Refining Technique, finding it incredible.

This initial-tier refining technique casually handed over by Huang Yaying, if placed in the real world, would certainly be something Celestial Immortals would fight for at any cost to acquire.

But here, Huang Yaying's casual demeanor clearly showed it as commonplace, not concerned about whether it was transmitted outside.

Sure enough, comparing oneself to others could lead to despair.

"Ding, you seem to vaguely have an understanding of the Low-Tier Refining Technique."

Seeing the system notification quietly appearing in his mind, Lu Ren didn't hesitate; with the learning ability of a Celestial Immortal, browsing through tens of thousands of words in merely two or three breaths was just ordinary.

He awkwardly maneuvered his True Power, casting several Spells imprinted on the bellows handle, activating them, seemingly made of white jade. When he pulled, he discovered it wouldn't budge.

Beside him, Huang Yaying, who had been watching him, chuckled: "How's that? I don't just recruit anyone; certain tasks cannot be performed by ordinary people."

Lu Ren, pondering the force on the bellows' handle, casually asked: "This job that includes room and board, plus a daily Spirit Crystal, only someone new like me would take it."

Converted to real world Huaxia's exchange rate, the purchasing power of that Spirit Crystal in Border City would be akin to one yuan, thirty yuan a month. Despite room and board, even black factories aren't this exploitative.

Huang Yaying didn't blush at all, confidently retorted: "Fellow Taoist Lu, that's wrong. I'm not taking advantage of you, the refining technique you received, though initial tier, would cost at least tens of thousands of Spirit Crystals to learn outside; having some living expenses is already quite good. Plus, room and board are included, work when there's work, play when there's none, which is quite free and easy."

Lu Ren shook his head, choosing not to comment, knowing that freshly arrived, this place along the Military Path indeed served as a relatively decent landing spot.

Immediately, he stabilized and stood firm, majestic True Power coursed through his muscles and skin membrane, his muscles bulged, shouting out loud.

Boom, boom, boom!

As if rusted gears were being moved, Lu Ren pulled the bellows handle, extracting it to hear the low, obstructed sound of wind whistling from within the white jade box.

"You can exert more force! If not, try to maintain it."

Huang Yaying's stern voice echoed, her hand rapidly casting countless spells while continuously taking out various strange materials to toss into the stone furnace for refining.

Seeing this, Lu Ren's competitive spirit flared; he expanded his Witch God Body, swelling to six zhang, while the Earth Path Principle lay dormant within his form. Under maximum release, an extensive, grand, and remote, yet primitively powerful aura seemingly emerged from the depths of chaos, continually circulating around Lu Ren.

With every move, Qi and Blood surged, more dazzling than the Great Sun. 𝐟𝗿𝐞𝚎𝚠𝐞𝚋𝕟𝐨𝚟𝐞𝕝.𝕔𝕠𝚖

With a somewhat perplexed Huang Yaying staring at him, Lu Ren said in deep, booming voice: "This bellows handle feels a bit too small."

"Haha, Lu the Kid truly surprises me!"

The Fire God laughed twice, then the stone furnace grew large as the furnace winds rose, soon towering over Lu Ren, simultaneously enlarging the bellows.

Lu Ren grabbed the bellows, feeling it fit quite well, then applied force to pull and push.

Boom! Boom!

With each push and pull, it seemed to absorb all tangible and intangible molecules within the surrounding space, releasing an intense roar as if a grand, earth-shattering battle was occurring.

"Maintain that!"

Huang Yaying's delighted voice sounded; her body emitted a sparkling spiritual light as she too enlarged, though clad only in a bra and shorts, her hands raised high, muscles bulging, countless tiny runes manifested on her skin, highlighting her profound mastery of body refinement.

Lu Ren, observing this, his heart slightly trembled, realizing he hadn't expected such a method within the body refinement path, using countless runes etched onto the body to constantly elevate one's physique.

Indeed, a technique worth learning.
