This news was a little too sudden. Even the Great Mechanic Han could not react to it instantly. He thought about it and realized that Aroshia had been at Grade C+ for quite some time. With her growth speed, it was indeed about time for her to enter Grade B.
In Aroshia's A ranked chain mission [Reboot], the requirement of the first round was to reach Aroshia and help her reach Grade B. The rewards were very rich—5,200,000 experience and one chance of a random reward. Han Xiao just happened to be in need of random reward chances, so this was an unexpected, pleasant surprise.
Aroshia was very special. She said that she had recently dreamed of many familiar images and that those might be the memories she lost. Every time Aroshia died, her memories would reboot, and she would forget everything before that. After so long, it was unknown how many memories she had lost.
"When you step through the doors of Grade B, there might be a special change," Han Xiao said.
