The reason is indeed a bit exhausting in coding, so this chapter is not finished yet. I truly regret using the leave note at the beginning of the month, so the update will probably be a little late, probably around one o'clock in the morning. By then, just refresh this chapter.
Sometimes I also think, when it's actually exhausting to code like this, should I just take a leave, but really can't bring myself to do it, which leads to the current situation. Every time, I ponder life, why keep writing? Isn't it better to honestly be a Programmer?
