Looking at the semi-transparent system panel that appeared before him, Mo Yuan gained a clearer understanding of his status. His cultivation was stable at Qi Refining Layer 5, and his physical body, thanks to the Divine Dragon Body Refining Art and the Progenitor Dragon Will, far surpassed that of peers in the same stage. His skills had also become more diverse, but he still needed to be cautious when facing the mysterious Black Fiend Sect.

"Black Fiend Sect Headquarters, Southwest Ancient Tomb Cluster..." Mo Yuan mused, his gaze falling upon the Gengjin Sword Qi Secret Arts and Divine Dragon Body Refining Art on the panel.

"My offensive capabilities currently rely mainly on Geng Metal Sword Qi, but it consumes a lot of energy. Although my physical body is strong, I lack effective close-combat techniques.

The Soul Cleansing Banner excels at dealing with soul entities but is weak against physical attacks. The Lightning Struck Wood Sword Embryo still needs tempering."

He realized that before venturing into the tiger's den, he had to further enhance his immediate combat power. With a thought, the system's sign-in opportunity refreshed.

"System, sign in at the current location (Outside Blackwater Town)!"

[Ding! Sign-in successful! Congratulations to the host for obtaining at "Outside Blackwater Town (Aftermath of Tribulation)": Low-Grade Spirit Stone x20, Gold Essence Fragment x1, Dragon Snake Eight Styles · Incomplete x1, Remnant Aura of the Primordial World: Weaponry Evil Qi (a wisp)!]

[Gold Essence Fragment]: A crystallization of sharp Metal Qi, usable to enhance the sharpness and toughness of Metal-attributed magic items.

[Dragon Snake Eight Styles · Incomplete]: A basic close-combat technique containing dragon-like and snake-like movements, with vicious strikes and tricky power. It complements the dragon physique perfectly.

[Weaponry Evil Qi (a wisp)]: A malevolent aura lingering from ancient battlefields, primarily for killing. It can be integrated into sword Qi or body-refining evil qi.

"Just what I needed!" Mo Yuan's eyes flashed. The Dragon Snake Eight Styles perfectly compensated for his close-combat shortcomings, while the Gold Essence Fragment and Weaponry Evil Qi could further enhance the power of his Geng Metal Sword Qi or magic items.

He immediately found a hidden cave and decided to enter a brief seclusion to digest his recent gains.

First was the Dragon Snake Eight Styles. With the boost from Primordial Comprehension, Mo Yuan quickly mastered these eight vicious and tricky combat techniques.

The first style, "Dragon Emerges from Shallow Abyss," was for charging and bursting. The second, "Serpent Coils on Perilous Peak," was for defense and counter-attack. The third, "Dragon Soars in Sea of Clouds," involved agile movement changes... As he practiced all eight styles, they integrated perfectly with his robust dragon physique. With every movement, gusts of wind roared, and faint sounds of dragon roars and snake hisses could be heard. His close-combat ability increased dramatically.

Next, he attempted to fuse the Gold Essence Fragment into the Lightning Struck Wood Sword Embryo. Using Innate Spiritual Energy to ignite a spiritual fire, he carefully liquefied the Gold Essence Fragment into a flowing golden light, which he then slowly permeated into the sword embryo.

This process was extremely demanding on his fire control skills and spiritual sense strength; any slight error could damage the sword embryo's structure. Mo Yuan focused his entire being, spending a day and a night, and finally succeeded!

The originally dark brown Lightning Struck Wood Sword Embryo now had fine golden patterns on its surface, resembling dragon scales. The sword body became longer and more slender, its weight increased, and it felt more stable in his hand.

With a gentle swing, a sharp aura spontaneously cut through the air, emitting a faint "hissing" sound. Although no formations had been inscribed yet, and it wasn't a true magic item, in terms of material and sharpness alone, it far surpassed ordinary mortal iron weapons. It could be called the "Gold-Veined Thunderwood Sword."

As for the wisp of Weaponry Evil Qi, Mo Yuan pondered for a long time before deciding not to integrate it directly into his Geng Metal Sword Qi. Instead, he attempted to guide it to temper his physical body.

The Divine Dragon Body Refining Art already contained methods for absorbing evil Qi to refine the body. Although the Weaponry Evil Qi was fierce, under the suppression of the Progenitor Dragon Will and the harmonization of the Innate Spiritual Energy, it was slowly absorbed. This made his muscles, bones, skin, and membranes even tougher, and his Blood Essence subtly gained a sharp aura of battlefield conquest.

Three days later, Mo Yuan emerged from seclusion. His aura was even more restrained, but when his eyes opened and closed, sharp light shot out. The entire person was like a sheathed sword – still as a towering mountain, but capable of earth-shattering power when in motion.

He wasted no more time, employing the Ghost Shadow Footwork and heading rapidly towards the ancient tomb cluster in the southwest.

Several days later, Mo Yuan arrived at a desolate hilly area. Strange rocks jutted out, vegetation was sparse, and the air was filled with a faint smell of corpse qi and decay. Unsettling energy fluctuations could be vaguely felt from underground. According to the confessions of the Black Fiend Sect members and the map, the entrance to the headquarters should be in this region.

He concealed his aura and moved like a ghost through the hills, searching. Finally, behind a pile of rocks in an extremely hidden location, he discovered a cave entrance concealed by an illusion formation. The cave was deep, with chilling winds blowing out, and the dense evil Qi was almost tangible.

"System, sign in at the Black Fiend Sect Headquarters entrance!" Mo Yuan silently commanded, acutely aware of the danger here and hoping the sign-in reward might provide crucial assistance.

[Ding! Sign-in successful! Congratulations to the host for obtaining at "Black Fiend Sect Headquarters Entrance (Convergence Point of Yin Evil)": Medium-Grade Spirit Stone x30, Realm Breaking Talisman (One-time use) x1, Aura Concealment Technique (Advanced) x1, Remnant Aura of the Primordial World: Earth Vein Dragon Qi (a faint wisp)!]

[Realm Breaking Talisman (One-time use)]: Can temporarily break or weaken low-level formations and restrictions.

[Aura Concealment Technique (Advanced)]: A more sophisticated method for hiding one's aura, which works even better in conjunction with Ghost Shadow Footwork.

[Earth Vein Dragon Qi (a faint wisp)]: The essence dragon qi contained within the earth's veins, which can nourish the physical body and aid in the cultivation of the Divine Dragon Body Refining Art. It provides a faint sense for dragon-related matters.

"Earth Vein Dragon Qi!" Mo Yuan rejoiced inwardly. This would be of great benefit to his cultivation of the Divine Dragon Body Refining Art. He immediately absorbed and refined it, feeling a subtle strengthening of the connection between his physical body and the earth.

At the same time, the Realm Breaking Talisman and the Advanced Aura Concealment Technique were precisely the tools he needed for infiltration.

He immediately practiced the Advanced Aura Concealment Technique, and his aura almost completely vanished, blending seamlessly with his surroundings. Then, using the effect of the Realm Breaking Talisman, he silently passed through the illusion formation and restrictions at the cave entrance.

Inside the cave was a narrow, downward-sloping passage. The walls were inlaid with minerals that emitted a sickly green glow, adding to the eerie atmosphere.

Mo Yuan held his breath and proceeded cautiously, step by step. Along the way, he encountered several patrols of Black Fiend Sect disciples, all of whom he easily evaded using his Ghost Shadow Footwork and Advanced Aura Concealment Technique.

The deeper he went, the heavier the evil Qi became. He could even hear low growls and the sound of dragging chains from the depths. Finally, the path opened up into a vast underground space.

In the center of the space was a massive blood pool, filled with countless white bones and struggling vengeful souls. Suspended above the blood pool was the nascent form of a dark red pill, exuding a dense evil Qi and the stench of blood—this was likely the "Evil Corpse Pill."

Around the blood pool, a massive evil formation was inscribed. Hundreds of black-robed disciples were chanting around the formation, injecting their own evil power and collected resentments into it.

And on a high platform directly above the blood pool sat a figure clad in a dark red robe, their face obscured by the shadow of their hood. Their aura was deep and unfathomable, far surpassing any opponent he had encountered before. They were likely at the peak of Qi Refining, or even half a step into Foundation Establishment!

Beside them stood a graceful woman wearing a black veil. Although her face was hidden, her cold and enchanting aura suggested she was the so-called "Holy Maiden."

Mo Yuan lurked in the shadows, observing everything, his heart filled with solemnity. This setup was far beyond the petty skirmishes in Blackwater Town. A frontal assault would be unwise.

His gaze swept across the entire space, finally settling on several stone pillars carved with runes at the edge of the blood pool. These pillars seemed to be energy nodes of the formation.

"Perhaps... I can secretly disrupt the nodes, create chaos, and then seize an opportunity," Mo Yuan decided, quietly moving towards the nearest stone pillar.
