After the group funeral, Ji Xinghe did not choose to leave the number six base immediately.
During the intermittent restoration of communication, he took advantage of his connections with the commander of the number six base to safely relay information to the number five base. A few hours later, during another bout of intermittent communication restoration, he received a response from the number five base.
"Grandpa, I'm behaving well, so don't worry about me. You need to look after your health and don't tire yourself out."
The response from Rong Xinyue was well-behaved. Because Su He and Shen Mu didn't say anything, Ji Xinghe had no idea that Rong Xinyue had secretly driven Star Moon to leave the base.
