When Luo Ziling went to Paris, he didn't inform Chen Xiaoyi about his travel plans.

Zhu Yijun and Shi Yidan did the same.
Because Luo Ziling had encountered too many unexpected events, and many people wanted him dead, Lin Lan, Zhu Yijun, and Shi Yidan were quite anxious.
They were even afraid that someone might do something outrageous and bring down the plane they were on.
