• heap the vessel with stones until it sinks to the identical draft
• deduce the pachyderm’s mass by summing the weights of the stones

这些表达**兼顾动词精准性与名词多样性**，瞬间提升语言档次。

实战演练：150词范文

Prompt: Narrate how Cao Chong solved the problem of weighing an elephant.

When the envoy from Wu presented a colossal elephant to Cao Cao, the warlord challenged his advisers to determine its weight. Scales large enough did not exist, and killing the beast was unthinkable. Six-year-old Cao Chong stepped forward and asked for a sturdy barge. He first ferried the elephant onto the boat and marked the waterline. After removing the animal, he ordered soldiers to load stones until the vessel sank to the same mark. By weighing the stones piecemeal and summing the results, the court obtained the elephant’s exact mass. Astonished, Cao Cao praised his son’s ingenuity, proving that wisdom is not bound by age.
