The MC's system is actually an inheritance artifact that's disguising itself as a system so as to more easily interact with its host, who comes from a modern world and was initially a fish out of water in the cultivation based world.
... the fact that MC is not the only transmigrator around. The current emperor and his grandfather are also both transmigrators, and they've already butterflied a lot of big changes into the annals of history. This is a Ming Dynasty which has built a great navy and preempted Europe in the Age of Sail. MC is the only one who got a golden finger with her transmigration though.
the young prince they rescue from the sea in the beginning chapters. Of course, he then disappears for 200+ chapters before returning to Chinese shores. Afterwards, it takes some more time before he realizes that he's fallen for the MC. And then even longer for MC and her family to accept his suit (since she's so young and the difference between their status so vast).
Also, even though he's not a transmigrator, the ML has a cheat of his own. He is able to read other people's emotions, and later, thoughts. People like transmigrators are immune to this ability, though. The way ML awakened to this power in his childhood was traumatic, and it was uncontrollable earlier on, causing him to have berzerker fits. Of course, MC is the ray of light who is able to bring him out of his berserk state.
Apparently, the founding emperor of the previous dynasty was a visitor from the real world too. In his fake imperial tomb, he left a note that has the location of the real tomb written down in English, which only the MC could read. Then in the real tomb, they find books and drafts of modern weaponry, as well as early experiments into explosives and guns. Though, the story is realistic in that the empire isn't advanced enough to immediately start mass producing guns yet, so only one gun show up near the end of the story.
MC's scummy white lotus sister is the cause of half her PR problems in the story, but all MC does is counter the attacks and come out on top of the PR fights, and then never even investigates who was the source of this stuff. Her dad's long lost half-brother teamed up with her sister to mastermind the accident that put her little brother in the ICU, and all they did was put the middleman in jail, and nothing ever gets done about the masterminds because "there's no proof". Every time you see the ML's eyes go cold because something bad happened to the MC, you expect him to take revenge on her behalf, but nothing really comes of it.
as a system-based quick transmigrator himself
From the chapter mid-thousands, early two-thousands, more an more of the narrative will be spent on the MC's adventures in the world of the system and system-users, as she tries to advance herself, build her own world, and endures various setbacks. These parts are a bit YMMV. I found them interesting at first because the MC starts interacting with other system-users and sometimes go on group missions to various worlds. But later on, I feel like the MC seems to get dumber every time she's outside of the mission worlds, like she's just asking to get herself killed, and often times acting just like the idiots that she looks down on and acts against during her missions.
That said, there's still a lot of interesting world building, and some very cool mission world arcs that I really liked. And it did hold my attention all the way to ch2971 (which is the current chapter as the story is a WIP). So I'm giving this novel an overall 4.
My favorite arcs are:
The second one as the emperor's sister, which was able to capture my attention for the rest of the novel, and also introduced the interesting emperor guy who actually pops up again later, more than once.
"That Phoenix Guy" arc, where the unfaithful/murderous husband the MC puts into jail later commits suicide and then becomes a fellow system-user, much to MC's (later justified) paranoia.
"The Merchant's Daughter" arc, where due to an incident in the previous mission, MC is directly dropped into a mission without any system help, which includes getting background info on who she is and what her goal is supposed to be. She has to figure it all out and deal with the unknown danger with only what skills she's retained so far.
"Demon Sect Lady" arc, where MC kills off the original ML of the world right after she arrives, and spends the rest of the arc trolling the entire rest of the setting.
That time the MC transmigrates in as the male emperor (not even the first time she's cast into a male body) and has to deal with a harem full of transmigrators, wild system-users, rebirths, etc.
The war arc that takes place in the system-level place between-worlds, where MC and a bunch of other high level mission takers get basically drafted to defend their corner of the multiverse against... bugs?rats? It's the first time we get to see a lot of the other major departments of the overreaching organization that manages the system-users.
such as the barbarian prince who swore revenge against our MC & ML, and whom the ML certainly had every intention of eliminating. He had every sign of being a villain boss, but that plot thread just vanishes afterwards, and the border war fades out to become a footnote. It wouldn't even have been an issue if there wasn't all that buildup and suspense to begin with. I even checked the other stories in the setting to see if it got continued there, but nada.
