Failure

When he was lighting the water, Feng Qingying quietly poured some powder into Huang Sanchao's cup.

After drinking the water, Huang Sanchao sat on a chair at the side and read the soldier's book. Suddenly, he started to yawn repeatedly, and very quickly, he was so sleepy that he couldn't even open his eyes.

Seeing that Huang Sanchao had fallen asleep, Feng Qingying quietly stood up. There were guards at the door, and if they did not summon them, they would not barge in for no reason.

She looked around and finally found a letter at the bottom of the table. This was a letter Yang Heng had written to Huang Sanchao.

She took the letter out and put it back in.

Then, he quietly took out the order badge on Huang Sanchao's waist.

To be exact, he wasn't sleeping, but had fainted, so she wasn't afraid of waking him up.
