Age of Warships: I choose to build stellar ships

Urgent task, I have to go to the train station to pick up my dad later, I can only have a chapter of 5006 words today, I will come back sooner tomorrow!

PS: Usually there are 2 chapters per day, but sometimes I have 10,000 words, sometimes 8,000, basically 4,000 for one chapter, 8,000 for two chapters, and 7,000 words in a few cases (occasionally 1-3 days).
