v2 Chapter 4： Send it, ask for a monthly ticket.

  Chapter 4 delivered, ask for a monthly pass.

Do you still have a monthly pass? It's the fourth update, take a break, and try to add another chapter later.

It's been hard work. Now my arms are sore and my waist is stiff. Please support me, let me give you a shout, and give me some more monthly tickets.
