"He alone can't protect him. What if you add me in?"
Just as the Demon Lord was about to make a move, the Yin Celestial Son's voice echoed all around.
The next moment, the Yin Celestial Son appeared before the Demon Lord, standing shoulder to shoulder beside the Heavenly Emperor of Returning Ruins.
The Demon Lord's heart jolted; he was confident about dealing with one Heavenly Emperor of Returning Ruins.
But add the Yin Celestial Son on top of that, and he no longer had that confidence.
Last time, he had fought together with the Yin Celestial Son and the Heavenly Emperor of Returning Ruins, and after an unknown number of rounds, he still hadn't won.
Since he hadn't won last time, then fighting again this time would be just as hard to win.
However, the Yin Celestial Son's appearance was only the beginning.
What really made the Demon Lord feel miserable was still to come.
"And me!"
"And me!"
Right after that, two more shouts came.
