Chapter 539 is brought to you by Dnton and alyschu.
This chapter was sponsored by Niles N, Amanda Z, Trevor L, Arnaud C, Ryan K, and John N.
Also, regarding Chapter 538 earlier today, the 'Bai Jie' thing was explained in the TL note a few hours later after it's posted by OverTheRanbow.
Here it is, for those who missed it:
"OverTheRanbow Note: Regarding the ‘Bai Jie’ thing at the end, there is a mature adult novel named “少妇白洁“, or “淫荡少妇之白洁”, aka “Lustful young milf Bai Jie”. Mars Gravity basically made a reference as a joke, don’t worry about it being significant to the plot or anything haha."
