Arknights, I Shall Raise Your Sister, So Worry Not!

BYD is also sufficient for fetal monitoring.

It's a pity. The previous book was quite good, just a bit short. I thought the Exusiai storyline wasn't affected because the halo distributed the charm to the older sister. I was looking forward to seeing the sisterly love story later, but it wasn't mentioned. I read a few Arknights fanfics and they were all just so-so, either about establishing the government or being pretentious. Then I looked for the new book and found that the author hasn't updated it... A profound and empty sorrow.
