When Jiang Li went to look for Ji Zhi, the latter was uncharacteristically not staying late to revise his official documents, but instead was telling anecdotes to Ji Kongkong.
"When the invasion of the Heavenly Demons from beyond this realm took place, the Nine Provinces were on the brink of demise. Your Uncle Jiang and I jointly combated the Heavenly Demons. At that time, he had just entered the Mahayana Realm and was not as invincible as he is now. Hence, he needed the assistance of a strong ally like me, your father."
"With the nation's luck on his side, your father wielded the Past and Present Sword, utilising the Path of Time to disrupt the temporal order, causing the Heavenly Demons to lose their sense of time and direction. The disoriented demons were detained by your father for a span of twenty breaths' time, which afforded your Uncle Jiang the opportunity to launch his offense."
