Lin Taichu understood. Arui and David had likely both been mentally controlled by this mysterious demonic energy.
At that moment, the soldier slowly spoke, but his voice had become exceedingly hoarse and strange. "You think reinforcing the seal means you can rest easy? How naive!"
Immediately afterward, the soldier's body began to swell and distort. Before long, he transformed into a gigantic Dark Demon Seahorse.
The Dark Demon Seahorse was pitch-black from head to toe, its scales gleaming with an eerie demonic light. Every scale resembled a sharp blade, and its eyes glowed blood-red.
Lin Taichu shouted, "Everyone, be careful! This is the Dark Demon Seahorse that controlled Arui and David! It can attach itself to people and control their minds!"
Hearing this, everyone's faces showed a mixture of fury and shock.
The King glared at the Dark Demon Seahorse, his eyes blazing with rage. "Today, we will destroy this monster completely and eliminate this future threat to Atlantis!"
As soon as he finished speaking, the mages launched the first attack.
Streams of light shot from their hands toward the Dark Demon Seahorse.
Yet the Dark Demon Seahorse remained unhurried. With a light flick of its tail, it stirred up a black Demonic Wind that blocked every one of the mages' attacks. Wherever the Demonic Wind passed, the seawater was dyed black and gave off a pungent stench.
Seeing this, Lin Taichu circulated his inner power and charged at the Dark Demon Seahorse.
The Short Blade in his hand flashed coldly as he thrust it toward the Dark Demon Seahorse's head.
The Dark Demon Seahorse nimbly dodged and swung its thick forelimb viciously at Lin Taichu.
Lin Taichu twisted aside, but the Demonic Wind still grazed him, slicing open his arm. Blood immediately poured out.
