Duan Mingyuan learned further details about the attack.
The main ship that was attacked belonged to the Adventurers' Association, a group of legitimate interstellar travelers certified by corporations and the Chamber of Commerce, distinct from the United Front's Rebels and Cosmic Pirates. The sudden attack not only wiped out the entire crew of the Assault Ship but also severely damaged the main ship of the Adventurers' Association, leading to the death of 174 adventurers.
This was a serious diplomatic incident, and representatives of the Adventurers' Association had already started negotiations with the Iron Guard Consortium.
This answered some of the doubts in Mingyuan's mind.
For example, why there were two Long Branch Guards escorting Billy Kaman.
It turned out that these two Long Branch Guards were not there to protect him but to prevent him from escaping or engaging in any other dangerous acts before taking control.
