I think people who have read enough cultivation/isekai to be hungry for a twist will find this to be a pretty interesting experience. It infuses a lot of science fiction content into the genre, and the setting itself brings different advancement concepts into play.
The setting is a future where advances in science have led to cultivation being deeply ingrained into society. During the ensuing forty thousand years of cultivation there have been major ups and down for Humanity, including a long "dark ages" period of collapse and a slow recovery. At the time of the story, Humanity has entered a new golden age, but the ever-present danger of demon attack means that becoming lax could lead to another downfall. The rise of the demons comes plausibly out of the science fiction style setting, as well, which is also a nice touch.
The beginning of the story focuses a bit on the MC's background of poverty and scavenging, but soon shifts to his efforts to move beyond that. To reach his goal to become a master refiner (an artifact maintainer and creator) he must enter one of the top cultivation-focused universities. To do that, he will have to show great potential for cultivation, in addition to the normal scholastic requirements. The MC's disadvantaged background that was focused on survival meant that he didn't have resources available to foster his cultivation potential, but it has shaped his attitude in ways that will benefit him greatly as he faces challenges on his road to cultivation.
While the MC experiences rapid progress and success during the course of the story, he does not become stupidly OP, and his ability to work with others on common goals becomes as important to his success as his significant personal strength.
Some of the more tedious parts of the cultivation genre are thankfully reduced here. For example, as of chapter 115 there has only been one family that does that thing where they focus on revenge and jealousy and harming the MC, even though it leads to their own downfall (big brain move there). While they will probably be followed by another at some point, the bulk of people (including opponents) the MC encounters are more mentally-balanced, and manage to grasp that they are part of a society that must function if it is to survive.
As one puts it, "It is because we are cultivators that we have to put others before ourselves. It is a cultivator's job to protect the common people!"
It is not a romance/harem-focused story. The MC does have close relationships with other people and is loyal to others, but his focus in these years is always on his goals. Perhaps he will include some romance as he progresses on his career goals.
Caveat 1: Look at the list of early chapters in the table of contents before you dive in. Some sites have two sets of chapters 1-5, with the first set being very poorly translated. If you are reading on a site like that, just skip the first set... the difference between them and the second set is like night and day.
Caveat 2: Proceed with caution if you are afraid of some occasional walls of text (especially earlier in the story). There are points where new lore or detail is introduced, and they don't waste a lot of pages on presenting that, so that means there will be one or more paragraphs to read at such times.
