I Am Very Sorry for Breaking My Promise
I thought I could update more on the long-distance train, but I didn't expect to suffer from the most severe acute gastroenteritis in recent years. Since I got on the train at noon, I have spent most of the time in the toilet of the green carriage.
The crew was very kind, but there was nothing they could do. Neither I nor the train had any gastrointestinal medicine, so I could only survive until I got home tomorrow morning by not eating or drinking.
So I'm sorry, I really don't have any energy to type on the keyboard now. I deeply apologize to the book friends who are chasing the update, and I will take a day off.
