Therefore, the incorrect preposition 〈In〉 is replaced with the correct preposition 『At』, as shown in the standard expression 『At 6:00』. This correction aligns with the fixed collocation rule 'at + specific time point' in English grammar, ensuring the accuracy of the time expression.

error_description: ① Punctuation Error: According to English writing conventions, the complete sentence 『At 6:30, I eat breakfast.』 and the following time adverbial 〈After〉 are two independent clauses and should be separated by a period. Therefore, the connecting comma is changed to a period 『.』 to ensure sentence structure integrity; ② Space Error: According to English punctuation rules, a comma should immediately follow the preceding word; there is an extra space in 〈After ，〉. It is corrected to 『After,』 to comply with standard formatting requirements; ③ Pronoun Error: Based on the context, the time adverbial 〈After〉 needs a clear referent; the pronoun 『that』, referring to the preceding action, is added to form the complete time adverbial structure 『After that』, maintaining sentence cohesion and grammatical correctness. The final correction is 『. After that』 to properly separate the sentences and maintain logical coherence.
