I was thinking about Xie Lian being able to snap the Xin Mo sword in half with his bare hands again, and then I thought to myself... "Wait, Xie Lian and Luo Binghe interaction could be really cute, though?"
Like, let's say that Xie Lian, during his time as a wandering trash god, accidentally falls into an interdimensional rift and ends up in the SVSSS world. His luck is bad like that. But while this is weird, sure, it's not that bad! The worlds are pretty similar and he can still make his living! So, Xie Lian wanders along as usual, curiously learning about this new world, picking through trash, occasionally punching demonic beasts to death to rescue awed civilians.
And at some point, Xie Lian runs into a young Luo Binghe while he's living on the streets. Let's say that Xie Lian rolls into town shortly before the death of Binghe's adoptive mother, has a few sweet encounters with this cute and kind child who doesn't have much to spare for a trash collector, and is there to comfort his new young friend when Binghe's adoptive mother passes away. Xie Lian is still there when Binghe gets thrown out onto the streets and he agrees to help the boy travel to Cang Qiong Mountain Sect.
So, Binghe gets to spend a month or two as a trash-collecting god's apprentice! He doesn't know that Xie Lian is a god. He suspects that Xie Lian is just a very powerful rogue cultivator who is living very humbly for some reason. The time isn't entirely pleasant, because life is hard and Binghe is grieving, but Xie Lian understands pain very well and is an excellent companion. He sees Binghe safely to Cang Qiong.
At which point, clingy Binghe does not want to separate from this extremely nice person, but Xie Lian insists on it. He wants Binghe to have a better life. He's worried that his bad luck will somehow spread to this poor boy who reminds him of so many other people he's loved and lost. Xie Lian supervises the confusing entrance exam, while the adult Cang Qiong cultivators desperately try to figure out who this strange person is (Airplane Bro is going "???!!!"), and then leaves wistfully. Binghe will later look back on this particular period of his life very fondly.
