Is “He was trapped in Zhuge Liang's Eight Trigrams Formation and rescued by Huang Chengyan.” true?

The official history in 「《三国志·吴书·陆逊传》」 contains no record of Lu Xun being trapped in the Eight Formation Diagram; in the novel, Huang Chengyan leading Lu Xun out of the Eight Trigrams Formation is an embellishment added for supernatural effect.
