I enjoyed this series as much as I enjoyed season 1. I just don't know why others feel disappointed about this series. Yes, they change the game into robot combat instead of CTF but if you'll follow closely, most of the details and game fights were according to season 1 since Wu Bai and Ai Qing's story happened on the same timeline of Han Shangyan and Tong Nian's story.
In this series you will learn why they name their team as KK and why he called himself DT. In this series you will also know that Wu Bai is the greenest green flag? I am amazed by how he planned on his pursuit for love and his dream.
