Vacation.

Hao Ren and Han Lingshi entertained the group of people, and also introduced Hao Mei to them. The young man said, "Miss Gram, me and Lingshi will be going in seclusion and we don't know when we will come out. In the meantime, my sister will conduct trade with you. I hope you don't mind that." 

Allyna was surprised by the sudden announcement, but she nodded, when she interacted with Hao Mei, she found Hao Mei to be easy to deal with than Hao Ren. The latter was just too tricky. However, Hao Mei was not to be underestimated either, if given a chance, the rapier would puncture the lungs and the enemy won't even detect anything. 

The reason Hao Ren and Han Lingshi put up this facade was to do something they have been planning for a long time. They wanted to go back to Blue Star and see how things were proceeding there, like a vacation.
