Bai Zhongqi, in the Star Alliance's initial formation plan, hadn't yet intended to include countries other than Country C, but this point could not be made clear to Country C, to prevent them from using it as a bargaining chip with Iridium Star.
Choosing to talk with Academician Ding rather than Zhong Zhiyan was also a deliberate decision by Bai Zhongqi. Apart from the fact that Academician Ding had a deeper understanding of the situation, approaching Academician Ding in the visiting delegation would not attract the attention of other countries, after all, it was just an old man going to the restroom. After returning to the dining room, Academician Ding kept clutching his pocket, which contained the smart device Bai Zhongqi had given him, and he dared not take it out to avoid drawing attention.
Even with his colleague Zhong Zhiyan, Academician Ding dared not reveal anything before they returned to Earth.
