The Black Tortoise Emperor let out a roar, the void trembled as if shattered.
Lin Yan and the other two's hearts slightly shook.
For some reason, the Furnace Elder, who had invited the Northern Black Tortoise Emperor, was filled with shock at this moment.
"This is bad!"
The Furnace Elder thought to himself, "I mistakenly believed that the Northern Black Tortoise Emperor had long been refined by me, and I had control! Now it seems, His True Spirit is still present, deserving of an Emperor's title... He has followed the Demon Venerable of Nine Heavens for too long, tainted with Demon Suppressing Energy, I underestimated Him."
Normally, this Northern Black Tortoise Emperor was almost controlled by Him.
But today's actions were completely beyond expectation.
He thought that the Northern Black Tortoise Emperor was being manipulated by him to deal with Lin Yan.
But at this moment, inexplicably harbored great hostility towards Lin Yan.
This hostility exceeded His expectations.
