《Men on the Ironclad》Ep18:Episode 18
In the night, a man jumped onto a warship and was subdued by Li WenZhang and You Baldy. The man committed suicide and Li WenZhang touched a small bamboo bar from his hand. Ding RuChang deduced from the figures recorded on bamboo sticks that this record is about the type and quantity reserves of the Beiyang navy ammunition. This means that Japanese spies have infiltrated the Navy Master Camp. In a serious situation, even Ding RuChang's dwelling windows are blocked by guards to prevent accidents.
