At this moment, I paused in a moment of thought. Removing the oxygen mask from this man would not cause a reaction from the system, but it might cause him to react vigorously, creating attention towards us. From my estimate, according to the hospital data, the nurses could visit him soon. It was good I came in a doctor's cloak. So without further ado, I gently tapped his acupoints and pulled out the mask.
I saw him steadily losing breath, so I quickly pushed a quarter of the broken breath pill (a pill that regrows damaged organs and tissues). The drug immediately melted like gas and slid down his esophagus effortlessly. It was good that the drug had no scent and taste. And before they could suspect him taking anything, the effect would have faded away. However, I did other things. Previously, I've thought a lot about these things stealthily, so I came up with a solution. I tested it, and the result was excellent.
