Maya wielded her knife from carriage 15 to 8, then back from 8 to 15. Whenever she confronted Frenzy, Lin Wu would spend his spare time shooting to support her. In less than an hour, the number of zombies from carriage 8 to the tunnel entrance had drastically decreased; their spawn rate couldn't keep up with Maya's killing speed. As for Frenzy, it didn't stand a chance; Lin Wu killed it repeatedly, and it hadn't reappeared since.
Stone was very perceptive; he once said that Maya and Lin Wu were kindred spirits in some ways.
Once the zombies had thinned out, Maya even suggested provoking the number 7 Blood Plague. If it had been anyone else, they would have thought twice, but Lin Wu was no ordinary person.
