The warrior's eyes change color because when the furnace operates at full capacity, the eyes also intake a large amount of energy released by the furnace, causing a change in pupil color.
This is similar to burning flames, where different flames show different colors. The color change of the furnace is also a sign of the warrior's strength enhancement, and the division of a warrior's level comes from this.
This rule applies to all warriors in the entire Federation, but when it comes to Lin Chen, it doesn't apply anymore.
Who made Lin Chen the first Immortal to turn into a warrior?
"My furnace color does not correspond to any warrior level color, but it does match the attribute color of my Heaven Deity. Dr. Ning, do you think this is the reason?"
Ning Xiuzhu paused for a moment, falling into deep thought, and after a long time, scratched his chin and said, "It seems to match as you said, you are Earth God, and the Earth attribute corresponds to yellow..."
