Scáthach looked at the lake of fire before her, smelling the acrid odor in the air, and frowned, saying, "Todd, it's time for you to go back. Leviathan and I still have a lot of work to do..."

Todd was taken aback, then suddenly remembered what he had wanted to ask earlier.

"Wait a minute, let's get back to the original question. You should know something about why the mermaids migrated, right?"

Hearing Todd's question, Leviathan moved its enormous eyes and looked down at the ground, saying, "Someone polluted the sea while using the Tyrant."

Todd was puzzled: "The Tyrant polluted the sea. Could you explain in detail? Who exactly polluted the sea? How did those creatures become undead?"

Leviathan and Scáthach remained silent for a long time.

Finally, Scáthach spoke up: "To tell you the truth... this all involves the Chosen Ones' War of the Crystals, and we cannot give you any more details."

Todd asked, somewhat incredulously, "Does it involve the War of the Chosen Ones?"

Leviathan replied, "We wish to resolve the conflict between races through the methods of Heaven. Crystal Constellation agreed to our approach, but on one condition: we must not interfere with the War of the Chosen in any way..."

Todd asked with a wry smile, "So you mean you won't give me any answers about this Tyrant Contamination incident?"

Leviathan said, "It is precisely because I cannot interfere in the War of the Chosen Ones and face the merfolk's predicament that I have no choice but to entrust them to you."

Todd was still somewhat unwilling to give up: "Can you give me some hints? Is it because of the resurrection ritual of the Sutherland sages?"

Scáthach shook her head vigorously and said, "We can't tell you."

Leviathan's voice was deep: "I'm sorry."

Todd closed his eyes in resignation.
