Boom! The fiery explosion illuminated the dim fourth level of the Earth Fire Demon Cave as Lu Yu punched the Four-armed Scarlet Fire Ape, breaking three of its arms, and nonchalantly extinguished the flames on his clothes.

The Four-armed Scarlet Fire Ape was engulfed in a purple-black flame. The Purple Flame Demon Fire caused it immense pain, driving it to insanity. Despite having three arms broken, it continued to fight Lu Yu head-on, resulting in all four arms bursting and breaking.

"Roar!" The Four-armed Scarlet Fire Ape let out a furious roar, creating ripples in the surrounding air. The place was already enveloped by Lu Yu's spiritual power, ensuring the sound of the battle would not attract more monsters.

Lu Yu learned this delicate skill of vibrating spiritual power at a specific frequency to neutralize sound waves during Li Qiuyang's lectures.

Training in subtle control of spiritual power is also a way to enhance the mastery of one's own strength—the finer the control, the greater the mastery over one's power.

Whew~ The Four-armed Scarlet Fire Ape ignited a crimson flame, struggling to expel the Purple Flame Demon Fire from its body. The snapping sound emanated from it, as the four broken arms transformed into four crimson flaming whips.

The Four-armed Scarlet Fire Ape was naturally immensely powerful with muscle and steel-like bones, usually relying on robust defense and unparalleled strength to crush its opponents.

As a demon beast at the pinnacle of demon force, about to break through to the demon spirit level, the Four-armed Scarlet Fire Ape had killed countless Martial Cultivators in the Form Accumulation Realm, including three at the realm's peak.

It never expected to be crushed by a human Martial Cultivator in its most proud domains—strength and defense—and this intensified the rage of the already insane ape, pained by the Purple Flame Demon Fire.

Crack! The flaming whip tore through the air, rapidly striking towards Lu Yu.

Lu Yu, with the dynamic vision of the Ice Jade Eyes, fully grasped the trajectory of the flaming whip. As it came down, Lu Yu's palm was already positioned at its target point, making it seem as if the ape struck at Lu Yu's palm instead.

Bang! The flaming whip was caught by Lu Yu and exploded.

The Four-armed Scarlet Fire Ape had promptly detonated the front half of the whip when it saw Lu Yu catch it.

Seeing the broken flaming whip restore its length, Lu Yu decided against further entanglement. With the Demon-Breaking Saber in hand, intent to kill arose within him, as spiritual power surged madly into the Demon-Breaking Saber.

One Strike Must Kill - Asura Slash!

Lu Yu's figure passed through the Four-armed Scarlet Fire Ape, appearing behind it, the ape's form stiffening before a blood streak slashed diagonally from its shoulder to its waist emerged, quickly turning into a fountain, spewing a wealth of blood.

The body of the Four-armed Scarlet Fire Ape split in two, falling to the ground lifeless.

After integrating the Thunder Saber technique, the power of Asura Slash increased, raising the damage from 2.5 times to 3 times, with the extreme power of One Strike Must Kill - Asura Slash enhanced to 5 times damage.

Lu Yu could blow apart one arm of the Four-armed Scarlet Fire Ape with a single strike, and 5 times the damage led to the instant destruction of the demon at the peak of demon force.

Walking to the Four-armed Scarlet Fire Ape's side, Lu Yu placed its corpse into the Storage Ring and called out to Zhou Tong hiding in the distance, "Lead the way."

Zhou Tong emerged from cover, heading to a specific area on the fourth level of the Earth Fire Demon Cave. He felt even more astounded.

He had personally witnessed Lu Yu going head-to-head with the strength-renowned Four-armed Scarlet Fire Ape, yet the ape's four arms were shattered, a shock difficult to express in words.

At this time, in Zhou Tong's eyes, Lu Yu had transformed from a formidable Sea of Qi Martial being into an exceptionally powerful Sea of Qi Martial being.

Lu Yu followed Zhou Tong towards their destination; the Four-armed Scarlet Fire Ape was not the first monster Lu Yu encountered—he had faced many demon beasts of peak demon force before.

On the fourth level of the Earth Fire Demon Cave, it could really be said that demon beasts of demon force are everywhere, demon spirit monsters are abundant, and only demon core monsters stand out.

Several times, the pair almost ran into demon spirit beasts, fortunately avoiding them as Lu Yu expanded his perception range beyond that of many newly-entered demon spirit beasts, sensing their presence in advance and taking detours.

After walking for an hour on the fourth level, they finally arrived at their destination.

If they went even deeper, Lu Yu would have considered leaving Zhou Tong behind and returning to the third level.

Venturing deeper into the fourth level of the Earth Fire Demon Cave, Lu Yu could not guarantee that he would always perceive demon spirit beasts first. Though monsters do not actively release perception, when Lu Yu's perception touches them, they instinctively counter-perceive.

When a monster's perception range exceeds Lu Yu's, Lu Yu's whereabouts will be exposed, leading to pursuit by demon spirit beasts.

In other places, Lu Yu might be interested in battling a newly arrived demon spirit beast to test if he had the strength to contend against the Sea of Qi level.

But here, any battle that can be avoided must be avoided by Lu Yu, even if he is confident in defeating the opponent.

Avoid unnecessary complications before the goal is achieved—this was Lu Yu's mindset.

Once he acquires enough Purple Flame Demon Fire, he can stir movements in the Earth Fire Demon Cave as much as he wants.

"The birthplace of the Purple Flame Demon Fire lies within the Forest of White Bones ahead; the Purple Flame Demon Fire in the third level is just the tip of the fire from the fourth level's Forest of White Bones. The true birthplace is within the Forest of White Bones," Zhou Tong said, looking at the Forest of White Bones before him.
