Last night, as usual, coded until the early hours of the morning. But at about 2:30 in the morning, the system suddenly popped up a dialog box, saying that the system was upgraded to Win10.

Well, I'll admit, I had a cheap hand, and I clicked OK. As a result, 30 chapters were lost. At that time, after the system became Win10, everyone was stupid when they saw that the manuscript was gone, and suddenly there was an urge to smash the computer.

It's really going crazy, and now it's a chapter that is gone. ay
