After everyone went their seperate ways, Hongjuan was going to visit a friend of his living in this planet. This friend was also a noble elemetavor but he had not taken any official noble position in any of the nations. Instead he was working as a technician in this border planet.
As for the reason why he was visiting this friend of his, that was because Hongjuan had a request for him. When he had pledged his loyalty to the Li family, they had added some functions in his terminal through which they were able to monitor the state of his planet which was suppose to be his private and very sensetive information. But to show their loyalty to the Li family, all the low ranking nobles joining them needed to do this.
But now that he had betrayed them and was working with someone who wanted to be enemies with the Li family, having this function in his terminal was extremely dangerous. That was why he wanted to remove it.
