Drakon of The Seven Armies – Chapter 2828

"The Demon Emperor's sleeping quarters are located above the Metal Hall. Once night falls, we'll enter through the Fire Hall. At that time, someone will guide you into the Metal Hall."

The seven-tailed blue wolf's expression turned serious as he said, "Once we're inside the Metal Hall, the prince and I won't be able to assist you anymore."

Isaac nodded and looked toward Zeux. He saw someone there with hands clasped behind their back, peering through the gaps in the dense foliage at the distant Demon Palace, seemingly deep in thought

As night fell, Isaac saw the five enormous buildings on the demon mountain light up with five different colors.
