My Healing Zanpakuto Cultivates Reiatsu

Qian Shoucheng, a medical Shinigami, only wants a quiet life in the safe 4th Squad. But his peaceful future shatters when the terrifying, battle-crazed Kenpachi Zaraki of the brutal 11th Squad corners him, demanding he demonstrate his healing. What Kenpachi doesn't know is that Qian Shoucheng's unique Zanpakuto, 'Sen Luo Wan Xiang,' allows him to plant 'Forest Seeds' that subtly siphon spiritual power from those he heals, turning his patients into unwitting batteries for his own hidden cultivation. Now, with the strongest, most monstrous Shinigami feeding his power, Qian Shoucheng's quiet life is over. But how long can he keep his horrifying secret from the man who could tear him apart, or the entire Soul Society?
