An Uninvited Guest

When the demon baron who had been following the three teams of human knights drew close to the island in the magma sea, those human knights had already landed on the island for a long time. It was not because that the demon baron didn't want to come here; instead, it was because of the utter difference between the environment above the magma sea and that in the mountain cave.

As it was very spacious and highly visible above the magma sea, which was radiating glow everywhere, if a knight flew above the magma sea alone, it would be very eye-catching. As there was almost no object that could cover the demon baron above the magma sea, the demon baron would be discovered from dozens of miles away. If someone among the human knights was watching through a telescope, the demon baron might have been discovered from 70 miles away.
