臣笑曰。五符經云。三仙王告皇帝曰。人所以壽考者。不食五穀故也。大有經曰。五穀刳命之鑿。臭五穀命促縮。此糧入腹無希久壽。汝欲不死腸中無屎。五府經云。黃精者三陽之氣。上太清宮。食之甘美。又長生也。未解老子何不嘗此。而嘗五穀腐人之腸乎。又三皇者皆神人也。何以不令子孫王於長生之國。而以五斗穀請子孫王於神州。求刳命腐腸之短壽乎又可笑耳。

Your servant laughs and says: The Wufu jing says that the three immortal kings told the Yellow Emperor, "The reason humans enjoy longevity is that they do not eat the five grains." The Dayou jing says: "The five grains are the chisel that cuts life short; the foul five grains make one's lifespan shorten and shrink. When this food enters the belly, have no hope for long life. If you wish not to die, let there be no feces in your intestines." The Wufu jing says: "Solomon's seal is the qi of the three yangs, reaching up to the Palace of Great Purity. Eating it is sweet and delicious, and grants long life." One cannot understand why Laozi did not taste this, but instead tasted the five grains that rot human intestines! Moreover, the Three Sovereigns were all spiritual beings; why did they not cause their descendants to rule over the realm of longevity, but instead begged with five pecks of grain for their descendants to rule over the Divine Continent, seeking short lives of cut life and rotten intestines? This is also laughable.
