I was delayed a lot the past few days, and I finally got some peace and quiet. I was thinking about coding for a whole day, and got up before six o'clock. But I just finished coding a chapter, and it took only two minutes to upload. There was an earthquake. I was so scared that I hurriedly closed the door. I picked up the computer and went downstairs. I just came back and took a look. The computer has rotated about 70 degrees! Now there are constant aftershocks and the computer is shaking unsteadily, making it difficult to continue coding! But don¡¯t worry, everyone, on average, there will be no shortage of three updates a day. Whatever the difference is, we will make up for it in the second half of the year. We will never default on the debt! (To be continued. If you like this work, you are welcome to subscribe and reward (this site). Your support is my biggest motivation.)
