815 Blood Sphere

"We're underestimating the Demon Emperor? You sound like you have encountered one before." They looked at Yuan with raised eyebrows.

"I guess you can say that." A smile appeared behind his mask.

"Well, I believe in them. They will definitely defeat the demon!" Lian Er said.

However, just as she said those words, the Demon Emperor suddenly released a deafening roar that shook the entire coliseum.

Yuan and the triplets immediately turned to look at the scene, and the Demon Emperor had suddenly grown a pair of bloody wings. Furthermore, the Demon Emperor grew in size, becoming twice as large compared to just mere moments ago.

Of course, its size was not the only thing that grew, as its killing intent and bloodthirsty aura also increased exponentially.

This shocked not only the spectators but the fighters as well.

None of them had expected the Demon Emperor to hide this much strength for so long.
