Lu Yu absorbed the sun star into his body (right eye), put on new clothes, closed his eyes, and communicated with the sun star in his mind.
The sun star rapidly enlarged in his eye, and then he saw a sea of fire, which was a very small part of the sea of fire that he had already refined. By continuously refining the void fire sea, the sun star would also grow stronger.
Urging the fire sea to expand in all directions, Lu Yu felt a resistance on the outskirts, needing to "exert effort" to expand outward. The expanded part would become a portion of the fire sea he refined.
After cultivating for a while, Lu Yu stopped and opened his eyes. The fire sea indeed expanded slightly, indicating that communicating with the sun star truly enabled him to refine the fire sea.
He just wasn't sure if being too far away would slow down the refining speed of the void fire sea.
Even if it might slow down, Lu Yu didn't want to stay here anymore.
