Yu Qi stayed awake watching Old Man Wong. She did not have anything to do other than wait for the blood test. She asked someone to bring her laptop here.
Someone must come here and inject the substance into Old Man Wong's body. The substance could not go in by itself. Yu Qi looked around. This was the VVIP room. There should be CCTV cameras somewhere around.
Yu Qi decided to look at the security system of the hospital. The system was very easy, and could not stop her from entering the system in a minute. If the technical team knew about this, they would be devastated.
There were about five cameras around the room. Three cameras were outside and two of them were inside. Yu Qi chose one of the inside cameras and watched the footage. She chose the time after she treated Old Man Wong this morning.
