What does 都 mean when added to 主 here: 主都知道，主都不在乎 This is a quote from “黑暗森林”， I've never quite understood the 都 there. Also, I've opened the book and tried a quick search, it seems like the author switches between 主都 and 主, which is entirely out of my HSK1 undertsanding.
都 (dou1) means &quot;all&quot; here. It is a separate word with 主, and its meaning unrelated to 主.
主都知道：主 knows all.
主都不在乎：主 does not care about anything.
