If you actually want to go to Fusang, there's no need to buy a ticket, because with Cheng Xuefei pinpointing the location, the Chess Herald can open a portal to send people there.
(If magicians were this useful, they'd have already been a hit.)
The actions against Fusang... no, specifically against the Huitian Organization, must be handled with utmost caution.
One must not underestimate the opponent; underestimating them might lead to unexpected failure at a critical moment on one hand.
On the other hand, international attention must also be considered.
Some kind-hearted gentlemen cannot stand such scenes, and when they hear about messing with the Fusang people, they act more hurt than if you killed their father.
So preparations need to be thorough, at least not giving those kind-hearted gentlemen any reason for reproach.
Cheng Xuefei has actually always maintained open communication; she has, in fact, already contacted Professor Li over there and is preparing to return.
