After giving instructions to Little Chan to stop by the room after midnight, Lu Xun retired to his quarters to cultivate.
First, he practiced the Nameless Technique, savoring the wave of pain before undertaking a session of the Sword Cultivating Technique himself.
The tiny sword within his Sword Heart was nourished, yet his body's strength remained the same as before, sticking at a progress bar of [Intermediate Spiritual Sword: 3%].
"According to the gentleman's explanation, each time I temper my body with the Sword Cultivating Technique, my Sword Heart can absorb it, but my body can't."
"But this energy hasn't dissipated; it's accumulated somewhere, and it needs the assistance of the Natural Sword Embryo."
To put it simply, it's like the Natural Sword Embryo is extremely sensitive, like a microscope, capable of detecting and utilizing this energy, something Lu Xun could not do.
