[_-] Master Chief is in the [4] bathroom of the [-ai] high school where he is growing a bunch of 艾 Chinese mugwort, that is currently 艹 flowering. He grows them in a gigantic 㐅 X that stretches from one corner of the tiled bathroom to the other. The high school students wonder why he is growing the 艾 mugwort, and why he won't let anyone step on his 㐅 X of 艹 flowers.
