So the ml asking the mc what other part of his body that can give to him wether if it's eyes, nose, mouth, ears whatever then he thought that foot is better so that the mc can't run away...
In the past the mc got caught by the guards because he wanted to escape then the emperor order the guards to break his foot then they broke it and the emperor said i won't hurt you anymore as long as you don't run away.
I just used google trans so sorry if it's not that accurate
