One logical issue: How did Leng know the eagles would just throw them off and not kill them? She guessed they had orders, but it was a risky assumption. If the eagles had decided to drop her from high up, she could have been seriously hurt. Then again, the trial rules seem to prevent harm, so maybe it's safe.
I wonder if the Princess knows more than she lets on. The teacher being a 'glitch' in her summoning feels like a secret she might be trying to keep hidden.
Wen Yao's character growth is subtle but noticeable. He starts off as just another faceless hater, but after spending time with Jiang Que, he's starting to question things. His shock at her feeding the White Tiger flatbreads and then buying meat buns shows he's not heartless.
I'm a bit iffy on how quickly Ling Chuan adapts to this body. The memory fusion is convenient, but the physical weakness should be a real problem. He mentions the body is weak, but then he's throwing punches and controlling fights easily. I'd like to see a moment where his body fails him, maybe an injury or exhaustion. That would make the struggle feel more real.
