If someone inquires about the reason for the delay, there are two primary factors contributing to it. Firstly, there's a family matter that requires my immediate attention. We've been dealing with a situation that both I and my family need to resolve, and it has been quite time-consuming.
Secondly, over the past three to four days, I've been working tirelessly to complete each chapter, and this has resulted in a significant lack of sleep. To stay awake and maintain my energy levels, I resorted to consuming energy drinks. However, I've reached a point where my body can no longer sustain this level of energy consumption. These combined factors have unfortunately led to the delay in finishing the sixth chapter. I sincerely appreciate your understanding in this matter.
