The reason Qu Jianlei ran to Zuo Jing was that he didn't want anyone to discover the whereabouts of Xiao Moshan and Flower Scorpion.
Whether or not he could get them off the Garbage Star, he didn't want anyone to find out their surface identities.
If you're going to hide, you hide from start to finish; just in case something happens again in the future… ptui ptui, that's a crappy assumption.
Anyway, every alias is cultivated with great difficulty; if possible, it's better to cherish them a bit.
So he came to Zuo Jing. If he kept tangling in Qianjing, the traces of Xiao Moshan and Flower Scorpion would be dug out sooner or later.
It wasn't that he distrusted his comrades, but that he was painfully aware of how powerful the Divine Text Association was.
Besides, on a place like the Garbage Star, there were no human rights to speak of. Whatever the Divine Text Association wanted to do, nobody would stop them.
