Chapter 410: Great Battle

"My subjects, heed my command: annihilate these invaders." The Mermaid King blew the War Conch, and all the Sea Demons present had their eyes turn blood-red; their blood boiled, and they charged at Meng Yifan and the others without a shred of fear.

They had lost their reason, becoming tools that knew only how to kill; even if they were to die, they would tear a piece of flesh from Meng Yifan and the others.

Lang Batian and the other three all wore solemn expressions; although they were Fifth Grade powerhouses, fighting in the deep sea required them to constantly expend energy to counteract the omnipresent water pressure, which suppressed their strength.

These Sea Demons, however, were fighting on their home turf; they had lived in the sea since childhood, and the seawater was like a mother to them, not only causing them no harm but providing them with assistance.

With one side waning and the other waxing, Lang Batian and the others found it extremely difficult to cope.

At the same time, the Mermaid King brandished his Trident, and the water currents where Meng Yifan and the others were located surged, creating whirlpools that pulled at their bodies repeatedly from multiple directions, making it impossible for them to even stand steady, let alone focus on the enemy.

Meng Yifan waved his right hand, and the Earth System World Power spread out, forming an earth-yellow platform in the surroundings that, like a Stabilizing Sea Needle, anchored the high-speed rotating whirlpools, allowing everyone to stand firm.

Then, Meng Yifan channeled the Wood-Type World Power, and as streaks of cyan light flickered, the omnipresent water plants on the seabed seemed to awaken upon being touched by this light; they grew crazily one by one, swaying constantly around Meng Yifan as if thanking him for granting them new life.

Meng Yifan pointed forward, and these dozens-of-meters-long water plants shot out, binding all the Sea Demons near him; sharp thorns grew from the edges of the water plants, piercing into the bodies of the Sea Demons and beginning to greedily absorb their flesh, blood, and energy.

Some Sea Demons were devoured until they were dried corpses, while others with powerful strength snapped the bonds of the water plants; both sides suffered casualties and fought fiercely.

"To capture the bandits, first capture their king!" Meng Yifan did not want to waste too much Wood Element and Earth Element Source Power; he gripped his Ghost Head Blade, executed Lingbo Microsteps, and with a flicker of his body, appeared before the Mermaid King.

"Woo! Woo! Wailing!" The Ghost Head Blade emitted the sound of Ghost Crying Wolf Howling, shaking the Mermaid King's mind.

During this time, Meng Yifan had slain many powerful enemies within the Secret Realm World, and the camp of ghost soldiers and ghost generals led by Zhang Butou had all devoured a large number of Yin Souls, causing their strength to soar rapidly.

The two main and deputy ghost generals, Zhang Butou and Jiang Tian, had already reached Fourth Grade Peak, and that group of ghost soldiers had all broken through to Third Grade Peak; the sound of Ghost Crying Wolf Howling they emitted at this moment had increased in power, capable of affecting the minds of Fifth Grade High Tier powerhouses.

The Mermaid King was stunned for a split second before regaining his senses, but in a battle between experts, victory or defeat is decided in an instant; while the Mermaid King was stunned, Meng Yifan's Ghost Head Blade had already slashed toward his neck.

At the critical moment, the Mermaid King's mind stirred, and he activated the Water-Type World Power; the seawater around him underwent a miraculous change, becoming viscous like glue, setting up layers of defense to block the advance of the Ghost Head Blade.

Meng Yifan felt it was very strenuous; the Ghost Head Blade felt like an ordinary person walking through a quagmire, and every inch of progress required overcoming immense resistance.

Taking this opportunity, the Mermaid King retreated at high speed, dodging the slash of the Ghost Head Blade.

"Yin-Yang Millstone! Annihilate!" Meng Yifan's mind stirred, and he unleashed his Yin-Yang Divine Ability; the Yang was below and rose, the Yin was above and descended, and the Yin-Yang Millstone rotated at high speed, squeezing the Mermaid King in the middle, intending to grind him into meat paste.

After Meng Yifan's realm had risen to Sixth Grade High, he had not yet begun to refine the world, so he could only be considered a Pseudo-Six-Rank; however, with the rise in his realm, his energy had also surged, and the Yin-Yang Millstone Divine Ability he unleashed at this moment was astonishing in power.

The two millstones were hundreds of meters in diameter, larger than a football field, and like two Yin and Yang worlds, they squeezed the Mermaid King.

The Mermaid King used his Trident to mobilize the power of the ocean, forming a massive whirlpool with the seawater to prop up the Yin-Yang Millstone; both sides fell into a stalemate, both consuming energy in large quantities.

"Yin and Yang generate and restrain each other!" Meng Yifan shouted loudly; based on his insights during this period, a strange change occurred within the Yin-Yang Millstone.

The Yin-Yang Millstone no longer separated; instead, they blended together—there was Yang within the Yin, and Yin within the Yang—and in some areas, they even merged, forming a black-and-white mixed gray energy.

This gray energy possessed strong corrosiveness and was extremely overbearing; it seemed that when this gray energy reached perfection, there would be nothing in the world that could not be corroded and nothing that could not be destroyed.

Although the Mermaid King was surrounded by Water-Type World Power, the gray energy emitted by Meng Yifan's Yin-Yang Millstone was so overbearing that it could even corrode the Water-Type World Power.

The Mermaid King's arm touched a bit of the gray energy and was instantly corroded, creating a large hole.

Not only that, but this gray energy was like a maggot on a tarsal bone, spreading rapidly along the wound on the Mermaid King's arm toward his body; terrified, he gritted his teeth and, like a brave warrior cutting off his wrist to survive, severed half of his own left arm.

That severed arm was corroded to nothing by the gray energy in the blink of an eye.

The Yin-Yang Millstone continued to rotate and squeeze, and streaks of gray energy were born in the middle of the millstone, powerfully corroding the Mermaid King's Water-Type World Power, which made him feel a huge crisis.

The Mermaid King possessed the Water Element World Origin and could mobilize Water-Type World Power; coupled with fighting on his home turf, his combat power was comparable to a Sixth Grade High powerhouse. At the critical moment, he shouted: "Surging Waves, Tsunami Filling the Sky!"

In an instant, the entire ocean was boiling, waves were rolling, and endless seawater gathered around the Mermaid King; he pointed forward, and the seawater condensed and took shape, turning into a several-hundred-zhang-long Five-Claw Divine Dragon that charged at the Yin-Yang Millstone.

"Boom—!" With the violent sound of the collision, Meng Yifan's Yin-Yang Millstone, lacking the support of World Power, was directly knocked flying; the Yin-Yang Millstone was broken, and the gray energy dissipated along with it. The Mermaid King escaped, cast a wary glance at Meng Yifan, and then turned and fled.

The Mermaid King fled in front, and Meng Yifan chased from behind; moving rapidly through the water, the Mermaid King was too fast, and with water waves swirling around his body to push him to accelerate constantly, Meng Yifan could not catch up to him even by continuously executing Lingbo Microsteps.

Although he had the Wood Element Origin for tracking and could sense the Mermaid King's position, if the Mermaid King was determined to flee, Meng Yifan simply could not catch up to him in the water. If he kept chasing like this, when would it ever end? Meng Yifan felt a strong sense of crisis, fearing that the National Teacher of the Great Wu Heavenly Dynasty would discover the secret of the Five Elements World, so how could he dare to waste a large amount of time here?
