On the day of the incident at Heijian Star, Gu Hang was already informed.
He had also set up a Star Language Tower, albeit with low power, sufficient only for "interstellar phone calls," unlike some more impressive Star Language Towers that could act like interstellar TV towers, capable of broadcasting across multiple star systems—valuable for both political propaganda and cultural products.
Gu Hang wished to build one of those in the future but given their high costs and the fact that basic interstellar communication was now somewhat functional, the priority for constructing a bigger and better Star Language Tower was not high.
That day, he received a communication request from his cousin. She was on a starship, informing him of the changes on Heijian Star and the fourteen merchant fleets from Gu Commercial Firm gathered in the Heijian Star System, facing internal strife and standoffs against each other.
He immediately began to prepare.
