Lord Xue Ying Spoiler It was after Xue Ying was crippled(poisoned) and he was living like a mortal, while he trains people students.. Swallowed Star Spoiler the last I read is when MC bought(?) the ownership of Earth from some (palace? Office?) in the galaxy. He bought it cause some kind of invasion from those 'aliens'..
Chapter 272 for Lord Xueying and Chapter 305 for Swallowed Star I don't know exactly where you left off but it's definitely around those chapters.
