It mentions he was earning rent from her and the old man.

At this rate, authors going for 2500 to 3000 chapters, which is insane but it just depends on the pace and amount of content the author has.

Read to ch 1100, undoubtably there is nationalism, but only in the early chapters (it's not even that bad. He's just prideful of his country, like a soldier). Some arcs are extremely long (netherworld arc). One of his goals has been stretched out well over 500chapters which has been frustrating. The 100x cultivation isn't used as cross-realm killing is one of the main things the human ancestors promoted (he goes to d rank fast, goes instantly to A/ spirit realm after couple hundreds chapters and has been there to forge the strongest possible spiritual abode), unfortunately one of his strongest abilities has been forgotten for the last 500 chapters. The MC is cunning and the "if you treat me good i treat you good" type person, the romance (isn't harem, which is what i prefer) is barely mentioned and is honestly mostly explained about how she has these unknown feelings (from mc's past life). The side characters often just follow him without saying anything for a few chapters (which i dont mind). The MC is set up for success and reaps the best rewards 99% of the time, this is because he is on a time limit due to the demon invasions. Despite all of this, i've enjoyable watching him get powerful and struggle against the odds. The world building isn't bad, the history between the human and demons unfolds with every arc. Overall, entertaining, translation is good.
