The strange owl-like sound was getting closer and closer to where they were.

An invisible sound wave entered their minds. It was all-pervasive and impossible to guard against, causing their distracting thoughts to run rampant. A desire to kill arose in their hearts.

"Oh no, it's a Magic Bat!" Ling Yun's mental strength was so strong that he woke up in an instant. His expression changed greatly as he shouted loudly.

But it was too late, Lin Xie and the rest were just warriors, their spirit energies had not fully formed yet, they were just like clouds floating in their spirit space, they were just too weak.

He did not have much ability to defend against the formless sound wave that contained the will to kill, and was quickly eroded by the killing intent. His eyes turned blood-red, and he wanted to use his weapon to attack his companions.

There was only one exception, and that was Luo Feng. He wasn't affected in the slightest, his eyes were clear, Lingyun thought a bit and understood the reason.

After all, Luo Feng was still a descendant of the Tyrant body faction. With the "Celestial Tyrant Manual" as a technique that defied the heavens, there was still the remnant will of the Tyrant Lord to protect him. It could be said that all evil was invulnerable.

Other than him, there was only Ling'er who was in combat and Qin Feng who was silently recovering from his injuries by using a spear to stand by the side without being affected too much.

Ling'er relied entirely on her strong Spiritual Energy. The all-pervasive sound waves were unable to pose too much of a threat to her. In her Spiritual Domain, she was completely annihilated by the waves of Spiritual Energy.

As for Qin Feng, although he was weak, he had the spirit artifact given to him by the Duke of Qin to protect his spiritual space. His entire body was enveloped in a layer of white, holy light, and was not affected in the slightest.

Ding!

A gentle breeze blew past, calming down everyone's state of mind. Ling Yun and the others who were still conscious, all of a sudden, raised their heads to look. It was the picture of the Nine Palace that was sluggish for a moment, and then slowly trembled, as an indescribable dao aura began to circulate.

"AHH!"

At this moment, a series of soft cries entered the ears of the people present. As they raised their heads to look, they could see that it was the young boys and girls who were eroded by the sound waves.

The sound of their vibrations within the Nine Palaces woke up, extinguishing the killing intent that was rising in their hearts.

"The Nine Palace Battle Array is indeed not simple!" Lingyun saw this scene and thought to himself, but now is not the time to pay attention to this.

They were in big trouble and needed to be dealt with now. Otherwise, they would be wiped out here.

When they realized that they had wanted to attack their companions, the youths all had apologetic looks on their faces. They broke out in a cold sweat, and soon after, a hint of anger and dissatisfaction emerged in their eyes.

Their cultivation levels were low, so they were easily invaded into the spiritual space. Even though they had firm wills, it was still very difficult to defend against them.

If such a thing were to happen again, and the Nine Palace Battle Formation was unable to help them, wouldn't it be a lifetime of regret if they were awakened?! I can't forgive myself.

"Phew!"

Lingyun let out a light breath, he was satisfied with the current outcome, he did not need to expend much effort to awaken Lin Xie and the rest, he could use all his strength to resist the incoming wave of Devil Bats.

"It's a magic bat. What do we do?" Ling'er waved her sword and destroyed all the black vines that were attacking her. She appeared beside Ling Yun in a flash, her brows tightly knitted as she spoke with a worried expression.

"I'm fine!" Lingyun's face was solemn, but he waved his hand, "The magic bats aren't very strong, they are only Class 1 Magical Beasts.

The sound wave attacks that you are good at are useless and are equivalent to toothless tigers, so they should not pose much of a threat. Also, don't forget, fire is the nemesis of the Magic Bats. "
