Chet walked towards Fai, who was smoking calmly at the end of the train, and asked for a pistol duel. Before the fight started, both of them were about to draw guns out from their holsters, Chet and all the villagers suddenly passed out and fell to the ground. Fai was confused about how this happened, since their guns are in the holsters. Shortly, a young man, as a representative of the new generation, appeared with a measuring tape and starting to measure the distance of the crime scene.
