New Arc notice

So, as you can see our journey is near to Infinity war which is more extravagant than the movie. That means I have to write one or two arcs before. I saw a lot of readers saying I need to write a technology arc. So, I am going to do that. Unfortunately, I don't know about Warhammer 40, but I do know about red alert and I really don't want our Boi destroy the world with his op power. Hence, I will seal like always to make sure he will progress with his mind. BTW I think scp would be nice too. Of course anomalies are kind of science fiction, but I can make it. What do you guys think about it?

1. Should I write just one arc?

2. Should I write 2 arcs with these two?

I really don't mind about it, but I can write mecha anime like Gundam. However, I thought it would be really boring. There are plenty of other mecha kind of movies and animes too, but most of their stories are just kinda meh. Meanwhile Ra and Scp kinda have a lot of directions and varieties.

So please write comment about this. I would be totally cool with your opinions if it is reasonable.
