Hope you're satisfied with my explanation (this's just my personal opinion) Spoiler C88: Replicate that card won't be easy, as it's stated in c84. C90: He didn't have enough time. Besides, he wanted to go in silence. And Zuo family and Ning family's relatioship is not friend. C92: The result of his Swordfish Training. And when facing death I don't think he really could care that much. C93: The Ning family didn't find anything valueable to them, so they tried to play the good guy. C94: Some common materials are free (c95). C95: He only took free materials. It's like you walk into a luxury restaurant and only drink water. C95: Three star is NOT more popular than four star. The card MC made is three star (less reuirement for the user), it's popular because its power equal to four star.
They didn't drop it, and I doubt that they retranslated anything (they've shown they're not above piracy before after all). It's just that the later chapters are all locked behind a paywall, and paywalled chapters don't get listed on NU.
