Twenty minutes later.
Qian returned to the surface.
Then, according to plan, he recalled the five shadow clones outside who had been practicing the two Dust Release ninjutsu in the sea.
Without any surprises, his "Dust Release: Detachment of the Primitive World Jutsu" rose by one level, going from lv1 (150/200) to lv2 (1/500)!
At that moment, a flash of insight suddenly surfaced in Qian's mind. After he fully digested it, he immediately felt that his understanding of this technique had risen to a new level.
Though it had not reached the point of a qualitative change, it was indeed much smoother to use.
Not only that, with the experience brought by its level-up as a reference, Qian felt that if he practiced "Dust Release: Atomic Dismantling Jutsu" again, he would not need to wait another twenty minutes and could level it up ahead of time.
Thinking of this, Qian simply stopped splitting off shadow clones to practice and personally went to the seaside, beginning to use "Dust Release: Atomic Dismantling Jutsu."
Just like that, in less than ten minutes, he grinded this technique up to lv2.
At this point, the two Dust Release ninjutsu he had just learned had both advanced to lv2.
And going from lv2 to lv3 required five hundred Proficiency points.
That was not something he could accumulate in a mere few dozen minutes.
Therefore, Qian was not worried that the process of his training midway would be interrupted.
So he once again used the "Multiple Shadow Clone Technique," split off five shadow clones, and had them go practice "Dust Release: Atomic Dismantling Jutsu" and "Dust Release: Detachment of the Primitive World Jutsu" respectively.
As for himself.
Naturally, he returned inside the volcano and began a new round of training.
Just like that, the days passed
