Noah began to improve his abilities and techniques according to the schedule that he had just established.
He didn't hide nor create a cave to go through those processes, the rocky wasteland with the lava lake was silent and devoid of any living being, it was perfect for his needs.
The surface of the wasteland was too hot for most rank 4 cultivators, and the rank 5 elders wouldn't spy on him out of respect for his status.
Also, he wanted to stay in the open to let his lungs freely absorb the light around him.
The power of his body backed his flames, they had instantly become one of his most powerful attacks after the breakthrough.
So, he wanted to nourish them by being in one of the most illuminated areas under the control of the Hive.
Modifying his martial arts was quite easy, he was their maker after all.
He just needed to perform a few tests to find the best balance between his physical strength and a somewhat sustainable expenditure of "Breath".
