During this period, Levi's other breathing techniques also improved.
Especially the newly acquired Giant Rhinoceros Breathing Technique and Raging Bull Breathing Technique, both of which were at the third level.
Of the two breathing techniques, the Raging Bull Breathing Technique and the Giant Bear Breathing Technique were about the same. According to Levi's judgment, based on the diagram, he could only cultivate it to the 4th level.
As for the Giant Rhinoceros Breathing Technique, which was a Non-Bloodline Breathing Technique, it had 24 tiny figures on it. According to Levi's speculation, it should be able to be cultivated to the fifth level, which was about the same level as the Siren Breathing Technique.
The Vortex Beast Breathing Technique was the slowest progress, which had only broken through to the second level.
