An unexpected discovery made Luo Zheng internally vigilant, but the other party did not behave out of line, so naturally, he couldn't be interrogated. Luo Zheng exchanged a few words with the captain, instructing the flight attendants to keep an eye on the person before returning to his seat to avoid suspicion from being away for too long. After sitting down, Luo Zheng whispered to Shi Qian: "Be cautious, this person might be a problem. It seems this flight won't be peaceful."
Generally speaking, such matters fall under the jurisdiction of the police or the National Security Department, and Luo Zheng doesn't need to worry. Yet, he felt uneasy and sensed that this matter was unusual, so he started paying attention, whispering a few words with Shi Qian, agreeing to take turns monitoring, ensuring one person rests while the other stays highly focused.
