Qin Qin and Lu Xue Zhen returned home, stayed for one night, and then trained in the space, which also significantly enhanced their Mysterious Spirit. Qin Qin discovered that exhausting the Mysterious Spirit to its limit could actually make the Mysterious Spirit within her body even more plentiful. This discovery made Qin Qin quite happy. Once the Mysterious Spirit inside her was replenished, she planned to first heal Qin An's hand. In fact, with her current abilities, healing Qin An posed no problem at all. However, if she didn't use the Mysterious Spirit to heal, Qin An's arm would always suffer a bit, and the recovery would be slower. If she used the Mysterious Spirit for the treatment, not only would Qin An suffer less, but his arm could also be restored to its former condition without any worries about potential lingering effects.
