This is a failed seal that sacrifices his own kind!

Just then, something unexpected happened!

The cracks on the black crystal container in the center suddenly widened, and a powerful and chaotic spiritual force of Tar erupted out, stronger than any it had ever encountered before!

The black liquid swept through the entire hall like a tsunami, crashing against the broken ice blocks of the ice shield fish around it, producing a piercing cracking sound!

"Oh no! The seal is about to completely collapse!" Gu Xi's expression changed, and he immediately manipulated the ice puck to retreat while activating his mental barrier to its maximum.

"Pfft!" Ais suddenly took a step forward, and an icy blue light burst from his body, trying to use his power to reinforce the ice blocks of his kin and delay the collapse of the seal.

But the power of Tar's mental energy is too terrifying, especially in this core area.

Although Ais's power was great, it was only a drop in the ocean under such a violent energy impact.

The black liquid continued to erode the ice, and even began to counteract the freezing power released by Ais.

"Ais! Come back! It's too dangerous!" Gu Xi shouted urgently.

At this critical moment, a green figure suddenly shot down from the shadows at the top of the hall, as fast as lightning!

"Buzz—!"

Countless emerald green vines appeared out of thin air, quickly wrapping around the black crystal container that was about to completely collapse, as well as the shaky ice shield fish blocks around it, just like living creatures.

The vines emitted a gentle yet resilient life energy, which temporarily stabilized the raging mental energy of Tar to a certain extent!

It's cowgrass!

Has it always been like this?!

"Pfft! Cowgrass? What are you doing here?!" Flamescale exclaimed in surprise and anger. "You deliberately lured us here?!"

Niu Niu Cao didn't turn around. At the tip of its vine, the tender bud that looked like an eye stared intently at the black crystal container, its tone carrying an indescribable complex emotion.

"If I don't lure you here, am I supposed to wait for the Tar spiritual energy here to fully erupt and pollute an even larger area of ​​the sea?"

Its vines tightened, the green life energy and the black spiritual power of Tar fiercely clashing, producing a "sizzling" sound.

"You knew about this place all along?" Gu Xi asked in a deep voice, his sharp gaze fixed on Niu Niu Cao.

The vines of the cowgrass trembled slightly, as if they were under tremendous pressure.

“...Yes.” It admitted with difficulty, “I know this is an abandoned virus research institute, I know they have conducted crazy experiments, and I know... they used the power of the Ice Shield Fish to try to seal the out-of-control Tal psychic power.”

Ais's icy gaze shot towards Niu Niu Cao like a sharp sword, "Why didn't you say so earlier?"

The cowgrass paused for a moment, and the green light on its vines dimmed slightly.

“Because… I need your power. Especially you, Ice Shield Fish.” Its “gaze” turned to Ais. “Only power of the same origin can completely purify or… take away the core here.”

"Take away the core? What do you want to do?" Gu Xi asked warily.
