As the lord of the Netherworld, Zu An should theoretically be able to command these underworld messengers like Ox-Head and Horse-Face and the Shackled General, but for some reason, he found that he couldn't contact them at all.

Is the problem with the authority of the Netherworld, or with these guys?

The Mermaid Queen said in a deep voice, "Please wait here for a moment. I'm going to lend them a hand."

They were not members of the sea tribe, and what happened here had nothing to do with them.

But as a fellow sea creature, seeing those guards who had faced death without flinching, and now that the army above was showing signs of faltering, how could she stand idly by?

As for the rule that one cannot approach the forbidden area on ordinary days, given the current situation, it's unlikely that anyone will care about that anymore.

As soon as she finished speaking, a stream of blue water swirled around her and drew her closer to the battlefield.

Then the Deep Sea Harp appeared in her arms, and this time she decided to pluck the strings herself.

Melodious music spread across the battlefield, and various notes shimmering with pale blue light landed on the sea creature soldiers. They immediately felt their fatigue disappear, and their condition was almost fully restored. At the same time, their strength and speed were much greater than usual.

"It's the Mermaid Queen!"

"Fight for the Queen!"

The army, which was on the verge of chaos and collapse, was instantly invigorated when they saw the beautiful figure in the sky. They roared and charged forward to kill the enemy, and their nearly broken formation was stabilized again.

The mermaid queens of the four dragon dynasties nodded in acknowledgment, and then led their experts to engage in battle with the bull-headed and horse-faced demons once again.

Seeing the situation on the field begin to reverse due to the appearance of the Mermaid Queen, Zaun couldn't help but sigh, "I think I know why your Holy Maiden has been able to lead you to so many victories."

Princess Peacock smiled and said, "They're still quite different. The Mermaid Queen is popular because of her beauty and her kind nature, while our Holy Maiden is more..."

Halfway through her speech, she suddenly realized: "That's right, in the end, they're all the same."

As long as it can unite the troops and get everyone on the same page, the methods will all lead to the same goal.

"Those monsters are incredibly powerful!" Princess Peacock suddenly exclaimed.

She discovered that whether it was Ox-Head and Horse-Face or those shackled generals, they were all incredibly strong and had an astonishing ability to recover.

More importantly, while various spells could cause some damage when they hit them, the effect was far less than expected.

It was as if they possessed extremely high resistance to magic.

These people seem to be born warriors.

However, with the Mermaid Queen's assistance, the morale of the sea tribe soldiers soared, and with more and more powerful sea tribe warriors coming to their aid, they gradually began to gain the upper hand.

The four Dragon Kings noticed that the monsters seemed to have high resistance to magic, so they transformed into giant dragons hundreds of feet long and rushed into the monster horde, causing chaos and knocking the monsters off balance.

Dragons are also known for their physical strength!

Although the monsters were muscular and burly, they were still too small in front of the hundred-zhang-long dragons. Soon, many of the monsters were torn to pieces by the dragons.

No matter how strong their regenerative abilities are, once they are divided into several equal parts, they will eventually be unable to recover.

"The Dragon King is mighty!"

"Welcome back, Dragon King!"

...

Seeing their ferocity, the sea creature soldiers on the battlefield erupted in thunderous cheers.

Princess Peacock breathed a sigh of relief: "It seems the sea tribes are on the verge of victory today."

Zuan, however, gazed solemnly into the depths of the canyon: "That's not necessarily true!"

No sooner had he finished speaking than a series of deep roars echoed from the depths of the canyon: "Who dares to harm my people!"

Suddenly, a giant hand rose from the canyon and grabbed the nearest North Sea Dragon King.

The dragon's body, hundreds of feet long, was so enormous that it was suddenly grasped by that huge hand, just like a python being caught by someone.

The Dragon King of the North Sea let out a mournful cry and twisted his body incessantly, but unfortunately he could not break free.

The other three Dragon Kings, united in purpose, attacked together upon seeing this, unleashing their most powerful skills, and finally managed to rescue the North Sea Dragon King.

However, the North Sea Dragon King had a distinct grayish-white handprint on his body, which looked exactly the same color as the deathly aura.

The North Sea Dragon King soon could no longer support his enormous body, and he transformed back into human form. He became extremely weak and unable to speak, and hurriedly used his internal energy to resist the invasion of the deathly aura.

The other three Dragon Kings were shocked and hurriedly used their spells to strike him. Even the Mermaid Queen promptly used healing spells.

If the Dragon King of the North Sea were to be corrupted by the deathly aura and transformed into a monster, the blow to the morale of the sea tribes would be devastating.

Fortunately, the North Sea Dragon King was powerful, and with the help of others, he finally managed to control the spread of death energy. However, he was unable to completely expel the death energy in a short time, and he probably wouldn't be able to fight anymore.

At this moment, a series of exclamations came from the field. Everyone turned to look and finally understood why the voices of the many sea creature soldiers were so frightened.

A bull-headed monster, as tall as a mountain, crawled out of the canyon.

He looked similar to the previous minotaur monsters, but his size was many times larger.

The minotaurs that were previously so large and imposing now seemed like ants compared to him.

His gaze swept across the entire area like lightning, and he saw many of his tribesmen's corpses. Visible white vapor spewed from his huge nostrils, and his eyes turned red. He swung the giant axe in his hand and cleaved it directly into the sea tribe's army.

He could see it clearly: the key figure on the field was probably the mermaid. With her assistance, the combat power of the entire sea tribe army had increased by at least 30%.

Kill the healer first when facing the enemy!

An immense pressure instantly enveloped the entire sea area. Those with lower cultivation levels were so frightened that they went limp, while others struggled to breathe, a chill running from their feet to their heads.

The opponent's axe came down simply and plainly, but the white line that surged up was as if the heavens and earth were splitting apart. No one would doubt that if this axe had struck, this underwater mountain range would probably have been cut in two, let alone the flesh and blood of the mermaid queen.

Many powerful members of the sea tribe were on tenterhooks upon seeing this, and they unleashed their ultimate techniques to bombard the giant axe in an attempt to save their dream goddess.

But those attacks were like ants trying to shake a tree in the face of that earth-shattering axe blow.

The Mermaid Queen tried to hide, but she found that her entire aura was locked, making it impossible for her to escape.

Left with no other choice, his ten fingers traced afterimages on the Deep Sea Harp, and strands of musical notes transformed into visible ribbons of melody that wrapped around the giant axe, attempting to overcome its strength with gentleness.

However, there are limits to the use of softness to overcome hardness. If the difference in strength between the two sides is too great, how can softness overcome hardness?

The giant axe was only delayed for a moment before it shattered the musical ribbons and struck the mermaid queen directly.
