Although unimposing in appearance, Gold Ingot was the sixth-ranked prodigy on the List of Monsters and the number one assassin of the Demon Slayer Sect. His strength was not to be underestimated.

His first move was enough to show Su Han his true power.

"Taiyi Golden Thunder!"

As Gold Ingot waved his hand, a golden thunderbolt roared out, tearing through the sky like a sharp sword or a pointed spear. It carried an aura of destruction as it shot straight for Su Han.

This was not a Martial Technique but a genuine bolt of lightning—a golden thunderbolt infused with Taiyi Qi. Its power was so formidable that it could easily demolish a ten-thousand-foot mountain, leaving destruction in its wake.

Although Gold Ingot lacked a Special Physique, he possessed a congenital treasure. This Taiyi Golden Thunder had been with him since birth, growing stronger alongside him and making it extremely precious. Far surpassing ordinary lightning, it contained the piercing sharpness of the Gold Attribute, capable of penetrating anything and slicing through solid steel. It was terrifyingly powerful.

Gold Ingot had not used his full strength; this Taiyi Golden Thunder was merely a probe. He wanted to force out Su Han’s secrets and claim them for himself.

"Samadhi True Fire!"

As the Taiyi Golden Thunder rapidly approached, Su Han’s mouth and nose glowed red. He then opened his mouth and exhaled a tri-colored flame, which howled forth and formed into a head-sized fireball to meet the attack.

The Samadhi True Fire was a Divine Method originating from one’s internal organs. It could not be extinguished by water, could incinerate all things, and was incredibly powerful.

BOOM!

The Samadhi True Fire and the Taiyi Golden Thunder were both extremely destructive forms of energy. Their mid-air collision resulted in a thunderous explosion, sending sparks flying and arcs of lightning shooting in all directions. The terrifying energy fluctuations rippled through the space.

However, this space was created by the Reincarnation Holy Mirror and was incredibly sturdy. Unless Saints were battling, not even an expert in the Supreme Realm could break it.

"What a formidable flame! This is not ordinary fire, but it’s not one I recognize. How interesting!"

Gold Ingot was not surprised that his Taiyi Golden Thunder was blocked. If Su Han could not even withstand a single bolt, there would be no need to go to such great lengths to kill him.

But that had just been an appetizer, and Gold Ingot was in no hurry. While Swordsaint and Lan Yi the Female Saint might not be able to defeat Saint You Heng and Master Gong Ming, they could certainly hold them off.

Furthermore, the flow of time within the Reincarnation Holy Mirror was slower than in the outside world—a day here was merely an hour outside. Therefore, Gold Ingot had plenty of time to battle Su Han.

"Earth Rank High Level Martial Technique: Thunder Dragon Heaven’s Roar!"

Gold Ingot attacked again, this time using a Martial Technique powered by his Taiyi Golden Thunder.

The golden lightning reappeared, weaving through the air with a sharp, destructive aura. It quickly coalesced into a hundred-meter-long thunder dragon, so vivid it seemed alive. The dragon even emitted a hint of a Heavenly Tribulation’s aura, like a Leviathan from the tribulation itself, intent on annihilating any existence that dared to challenge the might of the heavens.

"Go!"

With a wave of his hand, Gold Ingot sent the golden thunder dragon roaring toward Su Han. Its whiskers flew, its scales glittered, and its eyes held a murderous glint as it attacked with lethal intent.

"Ice-Fire Sixth Layer Heavens!"

Su Han did not hesitate, swiftly executing the Divine Method. The Samadhi True Fire and Triple Chilling Nether Qi were unleashed, intertwining to form a six-petaled Ice-Fire Lotus that shot toward the golden thunder dragon.

Neither the Samadhi True Fire nor the Triple Chilling Nether Qi were ordinary energies, so the Ice-Fire Lotus they formed was exceedingly powerful. As it clashed with the golden thunder dragon, an even greater roar echoed. The horrifying fluctuations turned into a storm that swept through the area, striking the space until it trembled as if about to shatter.

"Earth Rank High Level Martial Technique: Thunder Tiger Roar!"

Gold Ingot attacked again. The Taiyi Golden Thunder swiftly condensed, taking the shape of a hundred-meter-long golden thunder tiger. This creature radiated a terrifying, murderous aura, looking so fierce and maniacal it could make one’s blood run cold.

With the dragon and tiger now attacking together, the formidable power of the thunderbolts overwhelmed the Ice-Fire Lotus. It burst apart instantly, its flames and frost dissipating inch by inch until they vanished completely.

Su Han’s gaze hardened. Realizing his Ice-Fire Sixth Layer Heavens could not block the attack, he circulated his Demonic Qi and deployed another Divine Method.

"Rumbling Thunder Bagua!"

The Purple Lightning Yin Thunder was drawn forth, taking the form of the Bagua and condensing into a Thunder Tribulation Bagua Furnace that flew toward the thunder dragon and tiger.

With the addition of the Purple Lightning Yin Thunder, Su Han finally managed to stop the attack. Terrifying explosive shockwaves swept out, but both combatants remained unharmed; Su Han had his ultimate defense, and Gold Ingot was protected by his Taiyi Golden Thunder.

However, these two exchanges gave each a rough understanding of the other’s strength.

"Fire, chilling qi, and yin thunder... You really are full of secrets. Each of these energies is extraordinary. If any one of them were cultivated to the state of Great Accomplishment, it would not be weaker than my Taiyi Golden Thunder."

Gold Ingot’s eyes burned with excitement as he stared at Su Han. The more secrets Su Han possessed, the happier he was, because he believed they would all eventually be his.

Su Han remained silent, seeing no point in wasting words with Gold Ingot, but his opponent’s strength gave him a grave expression.

Although Gold Ingot had not used his other abilities, his Taiyi Golden Thunder alone was enough to reveal his power. His control over it had reached the realm of Great Accomplishment, allowing him to wield it as effortlessly as his own arm. He could even condense it into forms like the thunder dragon and thunder tiger, demonstrating astonishing skill.

Although Su Han possessed many Divine Methods, he was not a master of any single one. Of course, these ranged attacks were not his forte anyway; he excelled in fierce, close-quarters combat where he could unleash his full arsenal.

However, he chose not to engage Gold Ingot with his full strength just yet. He was biding his time, as the Great Majestic Demon King had not finished absorbing the Demon God’s hand bone. This meant Su Han was temporarily unable to use the Black Blade, putting him at a great disadvantage.

Gold Ingot wanted to probe his secrets, while he needed to wait for the Great Majestic Demon King to complete the refinement. Thus, both sides were intentionally dragging out the fight, but the battle had to go on.

From their previous two clashes, Gold Ingot knew that ordinary methods would not defeat Su Han. To force out his secrets, a stronger approach was needed. He decided to increase his power slightly to first suppress Su Han, then slowly apply pressure.

"Thunder God Physique, arise!"

Thunder Light surged violently around Gold Ingot, rapidly gathering above his head until it finally coalesced into a Heaven and Earth Physique.

This Heaven and Earth Physique was wreathed in golden lightning, appearing tall and magnificent. Although it had Gold Ingot’s face, it was completely different in form. It had the beak of a thunder god, a pair of wind-and-thunder wings on its back, and wielded a Golden Rod. It was majestic and boundlessly powerful.

This was the mythological Thunder God, which Gold Ingot had emulated to create his own Heaven and Earth Physique. The moment the physique appeared, it was as if the Thunder God himself had descended upon the mortal world, wielding all the thunder and lightning between heaven and earth, possessing the terrifying might to destroy the world.

"Physique Fusion! Su Han, show me what you’ve really got. Let’s see what you’re truly capable of."

Gold Ingot immediately executed Physique Fusion and looked down upon Su Han, like a deity gazing upon a mortal—supremely aloof.
