Long time no see, brothers.

I am very grateful to my brothers for accompanying me silently for almost 4 months. I never gave up when I was in a trough. When Black Powder went crazy, they would come out to support me. We can exchange views with each other in the future.At present, I am "returning" with a brand-new model. I hope that this time I can officially usher in the heyday, take every step down-to-earth and devote myself to it, and I will be outstanding.

Now I feel a little more comfortable, because every time I make a mistake, it's like the end of the world. If I can't find out the reason in time, my ending will be extinction. If you can be right once, you can be right countless times. You can be wrong once, and you can be wrong countless times.
