'Hey, you treated me yesterday, and I have to show my gratitude,' Old Master suddenly said.
'You... you, did Sister Ping tell you?' Wang Xiaoqiang asked in disbelief.
'Of course not. I know you all are hiding something from me,' the old man shook his head, 'Do you think I am a fool? To tell you the truth, I was very aware. Yesterday in the hospital, when you sat beside me, I felt a stream of energy enter my body, and then I fell asleep comfortably. You dare say that stream wasn't your doing?'
Upon hearing this, Wang Xiaoqiang nearly lost his soul.
Oh my God, Old Master Zhong has noticed. This is not good at all. If word gets out, wouldn't they drag me to a biological research lab to dissect me?!
'Old Master, actually that was me using Qigong to treat your illness...' Wang Xiaoqiang said evasively, uncertain whether Old Master would believe him, feeling a sense of trepidation.
