The structure の次に is used to express that something comes next after or is second to something else. It can indicate either sequential order (what comes after something in a sequence) or ranking (what ranks just below something).
When describing what comes next in a sequence or order, の次に indicates "after" or "following."
の次に is also common to say something is second to or ranked after something else. In this usage, it often pairs with superlative-like expressions to indicate the second-best, second-most, etc.
つぎ次 means "next" or "following," and the particle の connects it to the preceding noun. The particle に marks the time or position reference. Together, **Noun + の次に** functions adverbially, modifying what follows.Compare with のあと後で (after), which focuses on time ("after doing something"), while の次に emphasizes order or rank in a sequence.
