It's 500 chapters, and I didn't even think that I would be able to write 500 chapters and more than a million words. I persevered, and I'm still fighting for the promise I made when I first wrote the book. That is no eunuch, because I hate it very much. Although the results of the book are very poor, and my personal time is very tight, I still gritted my teeth and persevered, and from this diǎn point of view, I did not disappoint everyone. The book goes on, and I don't know where I'm going to write because I'm only halfway through my outline. And the science and technology tree planned for the development of the military industry above is only in the second stage, and there are several stages to come. I really wanted to write, but I didn't know if I could stick to it. This mainly depends on everyone's support for me. If everyone supports and gives strength, then I will naturally give back to everyone, and I will grit my teeth and persevere. I talk counts, just like I did when I first started the book. sent a diǎn small sigh, I hope everyone can understand, after all, it's five hundred chapters. I hope you can continue to support me, and your small gesture will be the motivation for me to continue to persevere. Love you, Stop Heaven!(To be continued.) )
