By the time the Devil Race baron following behind the human knights' party approached the island in the Sea of Magma, a long time had already passed since everyone had landed. It was not because the Devil Race baron did not want to follow them, but because the environment of the Sea of Magma was completely different from that of the passages and caves.
The space here was vast and visibility was extremely high. One glance downward revealed a stretch of scorching magma radiating red light. A knight flying above the Sea of Magma was exceptionally conspicuous, with virtually nothing to conceal his figure. He could be spotted from dozens of kilometers away. If anyone in the human knights' party had binoculars or something similar, the Devil Race baron might be discovered from a hundred kilometers away.
Of course, the Devil Race baron could also enter the magma. With the abilities of an Earth Knight, he could remain within it for several hours. But the consumption in magma was enormous, and his speed of advance was slow, so he could only fly above the Sea of Magma.
At first, the Devil Race baron had followed the human knights purely out of a desire for revenge—to kill human knights.
But later, when he discovered that the human knights had actually gathered three parties at once, with more than twenty Black Iron Knights in addition to three Earth Knights, his curiosity immediately gained the upper hand. Such a force would be considered extremely formidable even in the First Abyss.
Without sufficient cause and benefit, neither humans nor the Devil Race would casually assemble such a powerful force.
A few days ago, the Devil Race baron had seized an opportunity and cleanly killed a human Black Iron Knight.
It had been a probe.
