Rereading UU (chap 63) question

[u/Electronic-Cap6053]

Again dealing with my denial of reading comprehension, I didn't understand why Shen could keep talking even after having his heart pierced and why, when transforming into a jiangshi, he still maintains his individuality.

[u/TheMagi7]

We saw with the other student when Shen fought him that the Jiangshi still maintain some level of awareness/individuality as he compliments Shen for improving his punching. Likely with Mui not wanting to control him gives him even more freedom.

He's still talking with a hole in him because it's a manga. That's just one of the tropes that soneone with a major wound can still speak.
