《史记·七十列传·李斯列传》
二世认为赵高的话没错，想法办丞相，但但又担心情况不实，就派人去调查三川郡守与盗贼勾结的具体情况。
二世以为然。欲案丞相，恐其不审，乃使人案验三川守与盗通状。
The Second Emperor believed that Zhao Gao's words were correct, and he thought about how to do the Chancellor, but he was worried that the situation was not true, so he sent someone to investigate the specific situation of the collusion between the prefect of Sanchuan County and the bandits.
