earth 土 (54a) + dagger 戈 (32a) = wound 
Another “fused” character — “earth” and “dagger” share a stroke. Compare this with “I” (Character 32) all the way back in Chapter 3.

(In a self-defense class) “I want everyone to plunge their daggers into the earth before we start; I don’t want anyone getting wounded like in the last session.” / [No pronunciation needed]
